5 ORANGE COUNTY WATER SUPPLY FACILITIES WORK PLAN Fiscal Year 2007/2008 to 2017/ INTRODUCTION 1.1 Background In 1997, the State Legislature amended the Florida Water Resources Act (Chapter 373, Florida Statutes [F.S.]) to require the five water management districts to initiate regional water supply planning. Regional plans were required in all areas of the state where reasonably anticipated sources of water were deemed inadequate to meet 20-year demands. The St. Johns River Water Management District (SJRWMD) approved its most recent District Water Supply Plan in February 2006, with updates (addenda) approved in October 2006, December 2007, and May The South Florida Water Management District (SFWMD) adopted the update to its Kissimmee Basin Water Supply Plan in December In east-central Florida, the SJRWMD and the SFWMD both have determined that traditional water supply sources currently used in their districts will not be sufficient to meet the demands of the growing population and the needs of the environment, agriculture, and industry over the next 20 years. Historically, water supply and land use planning in Florida were handled mostly as separate issues. As potential limitations on the continued use of traditional water supplies became increasingly apparent in recent years, the Legislature enacted bills in 2002, 2004, and 2005 to more effectively address the state s water supply needs by improving the coordination between local land use planning and water supply planning. Significant changes were made to Chapters 163 and 373, F.S., to strengthen the statutory linkage between the regional water supply plans prepared by the water management districts and the comprehensive plans prepared by the local governments. A major component of these statutory revisions was the requirement for local governments subject to a regional water supply plan to prepare a 10-year water supply facilities work plan and to incorporate the work plan into the local comprehensive plan. Orange County falls within both the SJRWMD and the SFWMD and therefore must adopt its water supply facilities work plan within 18 months after the latter of the two water management districts approves its regional water supply plan. The work plan must address the planning and construction of public, private, and regional water supply facilities identified as necessary to serve existing and projected development, for at least a 10-year planning period, within Orange County s jurisdiction (i.e., unincorporated Orange County). Amendment of the County s comprehensive plan must also: Identify and incorporate the alternative water supply project(s) selected by the local government from projects identified in the updated regional water supply plan(s), or the alternative project(s) proposed by the local government [s (6)(c), F.S.] Identify the traditional and alternative water supply projects, bulk sales agreements, and the conservation and reuse programs necessary to meet current and future water use demands within the local government s jurisdiction [s (6)(c), F.S.] 1

6 1.2 Purpose This document represents the water supply facilities work plan (Work Plan) for Orange County (the County), as required by Chapter 163, F.S. This Work Plan includes data and analysis and a subsequent capital improvement plan to ensure that adequate water supplies and public facilities are available to serve the water supply demands of the County s growing population. An amendment to the County s Comprehensive Policy Plan (CPP) will incorporate this Work Plan as part of the Potable Water element, and additional revisions to other related CPP elements (e.g., Capital Improvement, Wastewater, Conservation, Aquifer Recharge, and Intergovernmental Coordination) will be recommended for consistency with the Work Plan. The Work Plan is intended to be a dynamic document, updated by the County at least every 5 years, within 18 months after the water management district governing boards approve updated regional water supply plans [s (6)(c), F.S.]. The data and analysis section of the Work Plan includes: An inventory of potable and reclaimed water service providers within the jurisdiction of Orange County The potable and reclaimed water service areas associated with the above providers A summary of existing facilities, design capacities, and permit allocations A summary of existing demands and a 10-year projection of anticipated total water demands for the major potable water providers A summary of existing flows and a 10-year projection of anticipated reclaimed water supply from each major reclaimed water provider An assessment of future needs within the planning horizon, via a facility capacity analysis noting capacity surpluses and deficits Development of a future water supply strategy to reconcile needs with available resources, including identification of planned traditional and alternative sources of water Identification of current and planned conservation and reuse practices and regulations Based on the capacity analysis, assessment of future needs, and selected water supply strategy, a capital improvement work plan is subsequently presented to implement the timely construction of public, private, and regional water supply facilities necessary to overcome any projected deficits within the planning horizon. These key capital improvement projects are updated by Orange County on an annual basis as part of the 5-year schedule of capital improvements included in the Capital Improvement Element of the County s CPP. 2

7 2 DATA AND ANALYSIS 2.1 Orange County Political Jurisdictions Orange County covers an area of approximately 1,000 square miles in east-central Florida. It is comprised of the unincorporated portion of the County, which is under the jurisdiction of Orange County government, and the following 13 municipalities (Figure 1): City of Apopka Town of Oakland City of Bay Lake City of Ocoee City of Belle Isle City of Orlando Town of Eatonville Town of Windermere City of Edgewood City of Winter Garden City of Lake Buena Vista City of Winter Park City of Maitland In addition to the above-listed municipalities, a special taxing district within Orange County, the Reedy Creek Improvement District (RCID), also has independent governmental jurisdiction. Established in 1967, RCID is the regulating authority for the Walt Disney World Resort and surrounding areas. RCID s jurisdictional boundary (Figure 1) covers approximately 18,800 acres in southwest Orange County, including the cities of Lake Buena Vista and Bay Lake and some additional areas of Orange County, plus 6,200 acres in Osceola County. The enabling legislation for the RCID provided it with many of the responsibilities of a city or county, including providing utilities, drainage, flood control, waste collection, roads and bridges, fire protection, land use planning, and enforcement of building codes. 2.2 Potable Water Service Providers in Unincorporated Orange County Potable water service in unincorporated Orange County is currently provided by the following significant public and private water supply utilities: Orange County Utilities Orange County Research and Orlando Utilities Commission Development Authority Apopka (City of) (Central Florida Research Park) Aqua Utilities Florida Taft Water Association East Central Florida Services Tohopekaliga Water Authority Mount Dora (City of) University of Central Florida Oakland (Town of) Wedgefield Utilities Ocoee (City of) Winter Garden (City of) Southlake Utilities Winter Park (City of) Zellwood Water Users The potable water service areas within the County associated with the above-listed utility providers are depicted in attached Figure 2. Orange County Utilities (OCU), a department of the Orange County government, is the largest potable water service provider within unincorporated Orange County. Another major supplier of potable water within the County is the Orlando Utilities Commission (OUC). Together, OCU and OUC account for the majority of the potable water provided to customers in unincorporated Orange County. 3

8 Four other significant utilities not on the above list Reedy Creek Energy Services (the utility provider for RCID), the City of Casselberry, the City of Maitland, and the Town of Eatonville provide potable water service within Orange County; however, their water service areas remain within their jurisdictional boundaries and do not contribute to the supply within unincorporated Orange County. For this reason, it is not necessary to address these providers as part of Orange County s Work Plan. In addition to the above providers, several very small utilities (e.g., Lake Ola Homeowners, Clarcona Resorts Condominium Association, Valley Mobile Home Park, etc.) provide limited potable water service within unincorporated Orange County. These small providers, however, have no potential for growth within their service areas and are therefore not addressed explicitly in this Work Plan. The 17 potable water service providers for unincorporated Orange County, as listed above, operate numerous water supply facilities, which are described in detail in attached Appendix A. All of these potable water providers currently use Floridan aquifer groundwater as their primary source of water supply. As summarized in Appendix A, Orange County maintains territorial/ joint planning area agreements with the other public and private water providers within the County to define service area boundaries and avoid duplication of service. When a proposed development in unincorporated Orange County requests potable water service, the Orange County Planning Division coordinates extensively with the appropriate provider(s) to ensure that sources and facilities will be available concurrent with the development. Attached Table 1 summarizes the existing capacities of the water supply facilities both source facilities (e.g., wells) and finished water facilities (i.e., treatment plants) operated by the two main potable water suppliers in unincorporated Orange County. Source and treatment facility capacity information for the other (minor) water suppliers was not readily available and therefore not included explicitly in Table 1. In addition, Table 2 presents a summary of existing consumptive or water use permit allocations associated with each of the 17 potable water providers in Orange County. 2.3 Reclaimed Water Service Providers in Unincorporated Orange County Wastewater treatment and reclaimed water (reuse distribution) services in unincorporated Orange County are currently provided by the following significant public and private wastewater utilities: Orange County Utilities Southlake Utilities Orlando (City of) Tohopekaliga Water Authority Apopka (City of) University of Central Florida Mount Dora (City of) Wedgefield Utilities Ocoee (City of) Winter Garden (City of) Orange County Research and Winter Park (City of) Development Authority (Central Florida Research Park) 4

9 The wastewater/reclaimed water service areas within the County associated with the above-listed utility providers are depicted in attached Figure 3. OCU is the largest provider of reclaimed water service within unincorporated Orange County. The City of Orlando also provides a significant amount of reclaimed water service within the unincorporated area. OCU and the City of Orlando jointly represent the majority of wastewater/reclaimed water service in unincorporated Orange County. One other large utility, Reedy Creek Energy Services (RCES), provides reclaimed water service within Orange County; however, the RCES reclaimed water service area remains within the RCID jurisdictional boundary and does not contribute to the reuse supply within unincorporated Orange County. For this reason, this reuse provider is not addressed as part of Orange County s Work Plan. The 12 significant wastewater or reclaimed water service providers in unincorporated Orange County listed above operate numerous water reclamation facilities, which are described in detail in attached Appendix B. As summarized in the appendix, Orange County maintains territorial agreements with the other public and private wastewater/reclaimed water providers within the County to define service area boundaries and avoid duplication of service. When a proposed unincorporated Orange County development requests wastewater or reclaimed water service, the Orange County Planning Division coordinates with the appropriate provider(s) to ensure that sources and facilities will be available concurrent with the development. Attached Table 3 summarizes the existing capacities both treatment capacity and reuse system capacity and projected flows of the water reclamation facilities operated by OCU and the City of Orlando, the two main reclaimed water service providers in unincorporated Orange County. 2.4 Demand Projections The population of Orange County is anticipated to increase by roughly 65 percent between 2005 and Due to the amount of developable land, the largest portion of this increase is expected to occur within the unincorporated portion of the County. Information on the County s population projections both for the entire County and for only the unincorporated areas is included in the data and analysis provided in the Future Land Use Element. The existing and projected future population within unincorporated Orange County (as presented in the Future Land Use Element) has an associated total water demand; however, this demand is met by a complex combination of supply from numerous public suppliers, along with a significant volume of self-supply (e.g., domestic wells, pond withdrawals, etc.). Each utility provider has its own territorial service area, which most often includes areas within both unincorporated Orange County and within municipal jurisdictional areas. The providers in Orange County each develop demand forecasts for their individual service areas and obtain consumptive use permits from the water management districts to address those demands. Although each provider is required to use a demand projection methodology acceptable to the water management districts, these methods often vary from utility to utility. For these reasons, estimation of total water demand projections directly associated with the population of 5

10 unincorporated Orange County is difficult, particularly if compatibility is required with the individual forecasts made by utilities as part of their permitting efforts. For this work plan, Orange County coordinated with the two major potable water providers (OCU and OUC) to compile data summarizing historic actual and future estimated total water demand within unincorporated Orange County. Demand met with water from these two providers represents the large majority of the total water demand in the unincorporated areas of the County. Although Orange County attempted to obtain additional demand data from the other (minor) suppliers providing water in unincorporated Orange County, this information was not readily available. Development of viable water supply plans and identification of required capital improvement work plan projects for these two main providers will effectively address the water supply source and facility concurrency issues associated with nearly all the projected future growth within unincorporated Orange County. Total water demand represents both potable and non-potable needs within utility service areas. For the two main suppliers (OCU and OUC), their total water demand within unincorporated Orange County represents only a portion of the total utility service area demand for which they are responsible. That is, these providers have additional demands in their service areas that occur within municipality boundaries or other areas not in unincorporated Orange County. Table 4 presents the water demands in unincorporated Orange County for each of these two potable water providers. The water demand projections shown assume average year rainfall conditions. Demands are typically higher during drought conditions and lower during extreme wet years. As noted in the table, the combined total water demand within unincorporated Orange County met by the two major suppliers is predicted to increase from 96.1 mgd in 2005 to mgd in 2020, an estimated increase of 65 percent. Appendix C includes supplemental information on the complete service area demand projections for OCU and OUC, the two largest potable water service providers in unincorporated Orange County. 2.5 Existing Capacity Analysis Through comparison of existing potable water supply facility capacities with projected total water demands, an assessment of future needs within the 10-year planning horizon can be completed for the two primary utility providers serving unincorporated Orange County. For these two potable water service providers (OCU and OUC), for which unincorporated Orange County only represents a portion of their responsible service area (e.g., OUC facilities provide water in the County and within the City of Orlando), it is not practical or feasible to determine exactly a subdivided portion of the capacity of their existing water supply facilities or permits that are specifically applicable to unincorporated Orange County. For this reason, the existing capacity analysis for these utilities is addressed for their entire service areas. Table 5 summarizes and compares, for the two primary potable water service providers serving unincorporated Orange County, projected total water demands with potable water supply capacities (both source and treatment facilities) and permit allocations. The table indicates that the combined current permitted groundwater allocation for OCU and OUC will be insufficient to meet all projected total water demands in 2010 through 2020; therefore, alternative sources of water (such as reclaimed water and future surface water) are required. 6

11 Table 5 also indicates that OCU s existing water supply source facilities (i.e., wells) will have insufficient annual average capacity to meet the projected total water demand in 2015 through 2020, and OCU s current average day treatment capacity may prove insufficient even sooner (by 2010). Without alternative facilities, the table also indicates that OUC may encounter a treatment capacity deficit by These deficits must be overcome through the planning, development, and permitting of additional traditional and alternative water supply sources and facilities. The planned water resource management and capital improvement strategy for Orange County water supply is presented in the following section, and specific OCU and OUC projects are listed in the capital improvement work plan section below. 2.6 Future Water Supply Strategy The potable water suppliers in unincorporated Orange County historically have used groundwater from the Floridan aquifer as the primary source for public supply. The water management districts have preliminarily determined that the acceptable level of cumulative groundwater withdrawals in this region will be reached by 2013 and, as a result, have implemented new Central Florida Coordination Area (CFCA) rules requiring public water utilities to augment groundwater supplies via the implementation of alternative water supply (AWS) sources. Consistent with the new rules, the water management districts have recently updated their regional water supply plans to present recommended strategies for integration of traditional and alternative water supply sources. Because Orange County spans two districts, water supply for the County is addressed in the current versions of the SJRWMD s District Water Supply Plan 2005 and the SFWMD s Kissimmee Basin Water Supply Plan Potential options for sources of potable and non-potable water are described in the regional water supply plans. In its regional water supply plan, the SFWMD identifies that water reuse, surface water, and stormwater recharge are currently the main options available for the Orange/Osceola County area of the Kissimmee Basin. The updated District Water Supply Plan 2005 of the SJRWMD identifies two categories of water supply source options (1) naturally occurring sources and (2) management techniques: Naturally occurring sources Fresh groundwater Brackish groundwater Surface water Seawater Management techniques Water resource development o Artificial recharge o Aquifer storage and recovery o Avoidance of the impacts of groundwater withdrawal through hydration o Water supply system optimization and interconnections Demand management (water conservation) Use of reclaimed water 7

12 In addition, dozens of specific, named AWS projects at various stages of development have been identified in the two regional water supply planning documents for potential implementation by water supply providers. Appropriate water resource development strategies, management techniques, and AWS projects delineated in the District Water Supply Plan 2005 and Kissimmee Basin Water Supply Plan have been incorporated into the development of Orange County s Water Supply Facilities Work Plan. Orange County has identified that its most effective course of action within the planning horizon is to: Optimize the use of groundwater from the Floridan aquifer Maximize the use of reclaimed water Continue aquifer recharge projects in areas of greatest benefit Expand reuse distribution facilities for irrigation and other beneficial use Continue to implement effective water conservation measures Develop additional AWS sources such as surface water for potable supply and nonpotable system augmentation Investigate additional options such as aquifer storage and recovery, reservoir storage, and stormwater reuse for future implementation as feasible OCU s operations within the planning horizon will be based on this water supply strategy. In addition, Orange County government will coordinate with, support, and encourage the other water supply providers within its jurisdiction to follow a similar plan. The development of AWS sources in Orange County will occur in coordination with both water management districts and other utilities in the region so that they will be available when additional groundwater is not available. The individual components of Orange County s water supply plan are described below in greater detail Efficient Use of Groundwater For the 10-year planning horizon considered in this Work Plan, fresh groundwater will remain the primary source of water to meet potable water demands in unincorporated Orange County. Orange County has invested in the development and application of extensive groundwater flow models, which serve as tools to better understand the natural system and optimize wellfield and beneficial recharge operations. The groundwater withdrawals of the numerous Orange County providers are widely distributed to minimize localized environmental effects. In addition, a significant percentage of the potable water distribution system pipelines in Orange County are interconnected. For example, the OUC potable water distribution system is fully interconnected. OCU s West, Southwest, and South Service Area water distribution systems also are interconnected, and, within the next few years, OCU plans to interconnect the East Service Area to its South Service Area, effectively linking the entire OCU system. These two largest potable water distribution systems in Orange County also have emergency interconnections between their two systems at several locations. The interconnected nature of the OCU and OUC distribution networks, along with many of the other water providers, creates an efficient, reliable, and flexible system. In the event that one or more water supply facilities are out of service, other facilities can provide water to the areas 8

13 affected by the service outage. In addition, groundwater withdrawals throughout Orange County can be optimized by redistributing pumpage to areas least likely to affect sensitive environmental features Expansion of Reclaimed Water Reuse East-central Florida has long been a leader in the application of highly treated reclaimed water as a source to meet many non-potable needs, including irrigation, industrial uses, and as a means of recharging the local aquifer system. In unincorporated Orange County, nearly 100 percent of wastewater is reused. Reclaimed water is a major alternative water source to be used as part of the County s strategy to supplement groundwater use into the future. Currently, all reclaimed water from OCU s four water reclamation facilities is beneficially reused for irrigation, industrial use, aquifer recharge, and wetland enhancement. Irrigation uses include residential, commercial, and agricultural public access reuse (PAR). The City of Orlando also reuses a significant percentage of reclaimed water produced at its three water reclamation facilities. The Water Conserv II reclaimed water distribution system in west Orange County uses reclaimed water from the County s South WRF and the City of Orlando s Water Conserv II WRF extensively for agricultural, residential, commercial, and golf course irrigation, and aquifer recharge via RIBs. Currently, the primary industrial use for reclaimed water in unincorporated Orange County is for cooling at the Curtis H. Stanton energy facility. Orange County will continue to invest in the development of reclaimed water reuse facilities in all of the OCU service areas. Future planned OCU projects include significant expansion of PAR irrigation systems. In addition, Orange County will coordinate with, encourage, and develop inter-utility agreements (wherever feasible) with other reclaimed water service providers in unincorporated Orange County, Orange County municipalities, and the surrounding region to maximize the beneficial use of reclaimed water to help offset the demand for potable water. Current consumptive or water use permit (CUP/WUP) conditions for many of the Orange County suppliers, including OCU and OUC, mandate the use of minimum annual volumes of reclaimed water for non-potable uses including land application and PAR irrigation according to given timelines (see Appendix A). The reclaimed water reuse plan for unincorporated Orange County includes meeting all permit-required reclaimed water use targets. In particular, OCU is fully committed to investigating and developing all feasible reuse opportunities in order to meet the requirements for minimum reclaimed water utilization volumes specified by Condition 27 of its SJRWMD CUP #3317 and by Condition 29 of its SFWMD WUP # W (as detailed in Appendix A). The County is actively expanding its reuse irrigation systems through the identification and planned development of supplemental supplies, where feasible and permittable. Sources of potential backup supply for the PAR systems include groundwater, surface water and stormwater. Many reclaimed water providers in unincorporated Orange County are investigating, permitting, and developing reuse system augmentation projects to facilitate the increased use of reclaimed water to reliably meet non-potable demands. 9

14 Additional activities being performed by Orange County and the various utilities that will expand the use of reclaimed water in the County and facilitate meeting CUP/WUP requirements for reclaimed water utilization include: Interim septic tank systems approved following Wastewater Policy WW2.1.7 will be required to connect to central wastewater where such facilities are available (Orange County Wastewater Policy WW2.1.8) The County s utility capital improvement program (CIP) includes funded projects to implement the retrofit of existing septic tank systems with central wastewater service where feasible (CIP number 1505) Where economically practical and feasible, the County will maintain existing and develop new wholesale potable water and reclaimed water service agreements Continue to encourage the selling of reclaimed water to other users, such as golf courses, for their use in meeting landscape irrigation needs that will offset their use of groundwater (Wastewater Policy WW2.3.2, Aquifer Recharge Policies AR and , Potable Water Policies PW2.2.8 and PW2.2.9) Continue to require by ordinance connection of all new developments to the reuse system, provided that service is available (Wastewater Policy WW2.3.3, Orange County Code Section ) In creating County land development regulations to facilitate aquifer recharge and reduction of potable water demands (Conservation Policy C1.11.5), the County will investigate the feasibility of retrofitting existing residential and commercial development to use reclaimed water for landscape irrigation Continue to expand the existing system of reclaimed water metering, and continue to require individual metering of reclaimed water connections to single-family residential customers on public streets (Wastewater Policy WW1.3.5) The County will implement feasible options to use all available reclaimed water supplies for beneficial applications (Wastewater Policy WW2.3.1) Investigate the feasibility of using a water-conserving rate structure for reclaimed water customers (Wastewater Policy WW2.3.4) Enhancement of Aquifer Recharge Orange County has long been a leader in the development of aquifer recharge enhancement projects using reclaimed water. Orange County and the City of Orlando currently send a combined total of about 16 mgd of reclaimed water to rapid infiltration basins (RIBs) of the Water Conserv II system in western Orange County and eastern Lake County. Due to the hydrogeology of that region, these RIBs have been shown to be highly effective at recharging the Floridan aquifer. Reclaimed water from OCU s Northwest WRF is currently used for 5 mgd of beneficial RIB and lake augmentation recharge to the Floridan aquifer. Several other reclaimed water providers in Orange County, including Apopka, Ocoee, and Winter Garden, also utilize RIBs to recharge the potable water aquifer in the high-recharge zones of western Orange County. 10

15 In conjunction with the SJRWMD, Orange County recently completed the Central Florida Aquifer Recharge Enhancement Phase 2 study, which: Developed a methodology to evaluate the effectiveness of artificial recharge projects in Orange County Identified potential recharge projects in Orange County Compared and ranked artificial recharge projects in Orange County The County s Work Plan includes capital improvement projects to continue to expand aquifer recharge in the most beneficial areas of the County. Additional RIB and lake augmentation projects are planned in the OCU West Service Area to help offset proposed groundwater withdrawals Continuation of Water Conservation Efforts Orange County currently administers a significant water conservation program, staffed by a fulltime Water Conservation Program Manager and three additional full-time staff, as well as additional contract staff. Additionally, the County maintains a comprehensive Water Conservation Plan document, submitted to the water management districts during recent permit modifications, which is consistent with the County s CPP and which includes Orange County s adoption of ordinances that: Limit lawn and ornamental irrigation hours (Potable Water Policy PW2.2.10) Encourage Florida Friendly landscape (Potable Water Policy PW and Conservation Policies C and C1.11.4) Require ultra-low volume fixtures (Potable Water Policy PW2.2.13) Require rain sensor devices, mandatory for new construction and for extensive retrofits of existing sprinkler systems (Potable Water Policy PW2.2.11) Provide for a water conservation-based rate structure (Potable Water Policies PW1.7.1 and PW1.7.2) Additionally, the County s water conservation practices include the following: Florida Friendly Landscape Workshops for the public and home improvement store nursery managers and assistant manager Water Watch water restriction program patrols handing out educational notices and enforcing codes Water Use Audits for customers with high water uses, as well as handout of the survey method to school children and home owners associations (Potable Water Policy PW ) Toilet Retrofit Program offers vouchers up to $100 per toilet to replace existing highflow toilets with ultra-low-flow toilet models; installed 513 fixtures in Distribution System Leak Detection using sounding techniques while technicians perform maintenance on hydrants and valves Low-Flow Shower Head and Garden Hose Kits given out free at community events and meetings Presentations and Events at the mall, home owners association meetings and community events: giving out of conservation materials, educating how to detect and repair leaks 11

16 School Events: Blue Thumb Junior Detective Program, Touring the Water Facts, Tap into a Career in the Water Industry, Girl Scout Water Festival, and the Billy Drop Program Attendance at conferences about water management and conservation, including AWWA, University of Central Florida, Florida Water Resource Conference, and the Florida Statewide Conservation Commission SJRWMD Water Conservation Public Awareness Campaign to which Orange County contributes annually In May 2008 Orange County adopted an updated, more stringent water conservation ordinance (Ordinance ; Orange County Code Sections through ). Although the previous water conservation ordinance restricted landscape irrigation in Orange County to only two days per week with no irrigation allowed between 10 AM and 4 PM, the revised ordinance defines the precise days of the week based on house address, providing for easier enforcement. The new ordinance applies to all water users, even if they irrigate from a well or a pond. Agricultural, golf course, and reclaimed water uses are currently exempt from the rule. As the water management districts continue to reassess and update their watering restriction regulations in the future, Orange County likewise will review its water conservation ordinance and revise it when necessary to maintain consistency. To reduce future demand for water, Orange County will continue to implement the extensive water conservation program components described above. New proposed Conservation Element Policy C provides enabling language in the County s CPP for implementation of these measures, and for periodic assessment of the water conservation program. All Orange County water conservation-related policies and ordinances apply to all areas of Orange County, including municipalities, unless those municipalities have their own water conservation ordinance(s), which will overrule. In general, all areas of Orange County follow water conservation rules that are generally consistent with the conservation requirements set forth by the water management districts, including constraints on day-of-week and time-of-day allowed for irrigation. Orange County will continue to use a water conservation rate structure for OCU s customers (Potable Water Policies PW1.7.1 and PW1.7.2) and implement water conservation and shortage regulations including the specific restrictions of the SJRWMD and SFWMD during declared water shortages (Potable Water Policy PW2.2.12). The County maintains a five-tier inclined block rate structure that promotes water conservation. As of Fiscal Year 2008/2009, rates start out at $0.98 per thousand gallons for the 0-3,000 gallon block and climb to $7.43 per thousand gallons for any residential use above 30,000 gallons per month. Orange County supports the use of innovative water conservation techniques and strategies as they become available. The County will strive to maximize the conservation of water resources through coordination with SJRWMD and SFWMD and through implementation of County and other agency programs Investigation of Aquifer Storage and Recovery Aquifer storage and recovery (ASR) can facilitate the use of water supply sources, such as surface water or reclaimed water, which have significant seasonal variations in availability. In a 12

17 cooperative project with the SJRWMD, Orange County is studying ASR feasibility and has assisted in the installation of an ASR pilot well in the eastern part of the County (under capital improvement schedule [CIS] Project Number 1550) (Potable Water Policy PW3.1.8). If the results of the pilot study indicate that ASR in eastern Orange County is technically, economically, and environmentally feasible, the County intends to include a full-scale ASR project in its future capital work plan Development of Surface Water As incorporated in the conditions of recently issued CUPs and WUPs, the water management districts are enforcing a water resource strategy for Orange County that caps groundwater use for public supply at projected 2013 demand levels. This constraint is being placed on all significant potable water providers in Orange County. To accommodate growth beyond 2013 and to supplement groundwater and reclaimed water supplies, utility providers are investigating and advancing plans to develop and construct small and regional-scale surface water AWS projects. Due to economies of scale and the need to develop such sources at minimum capacities that often exceed the projected needs of a single utility, most of the proposed surface water AWS projects require extensive coordination and cooperation amongst regional utility providers. Orange County is participating in the advancement of additional surface water sources as necessary to meet future demands. The County will focus on efficient, cost-effective, and technically feasible alternative sources that do not cause adverse impacts to water quality, wetlands, aquatic systems, springs, or other environmental systems. Per its current permit conditions, OCU is required to develop a minimum 10-mgd AWS facility by 2013 to supplement its SJRWMD groundwater allocation and another 10-mgd AWS facility by 2014 to supplement its SFWMD groundwater allocation. OUC also has a requirement in its SJRWMD CUP to develop at least a 5-mgd AWS project by Currently, OCU and OUC are partnering with the City of Cocoa, City of Titusville, Tohopekaliga Water Authority (TWA), East Central Florida Services, Inc., SJRWMD, and SFWMD to plan, design, and construct the new St. Johns River/Taylor Creek Reservoir Water Supply Project. This source will provide up to an estimated 50 mgd of surface water for the populations served by the project partners, a majority of which will reside within Orange County. Funding for development of this surface water supply will be split among the project partners, with the potential for co-funding from the state or federal government. OCU has committed to receive at least 10 mgd, and OUC has committed to receive at least 5 mgd, of new alternative water supply from this project. Due to multiple political, permitting, and environmental issues beyond the control of OCU or OUC, however, it will not be possible for this AWS project to be constructed and producing water by Issues such as delays in obtaining necessary information from the water management districts, federal requirements for an Environmental Impact Statement (EIS), consumptive use permitting uncertainties, and anticipated public objections and legal actions are expected to push this project back until at least In an effort to develop an additional AWS source that would be available by 2013, OCU was pursuing the Southeast Reuse Augmentation/Water Supply Project (as listed in the SFWMD Kissimmee Basin Water Supply Plan). However, the permit application submitted by OCU for this project was not granted by the SFWMD. 13

18 OCU also is participating in regional discussions with other utility providers to develop additional surface water projects as feasible from locations further downstream on the St. Johns River and from potential locations within the Upper Kissimmee River Basin. Unfortunately, it likewise will not be possible for these other potential surface water AWS projects to provide water by For example, the potential St. Johns River at State Road 46 Project is already behind the St. Johns River/Taylor Creek Reservoir Project in schedule, and it faces all the same issues as that project. Based on recent experience, new surface water supply projects are likely to face significant legal and permitting challenges that will delay start-up of any regional-scale facility. Additionally, the SFWMD has delayed the possible permitting or development of any surface water supply projects within the Upper Kissimmee River Basin until they complete a current study and plan for restoration of the Kissimmee River and modification of the operational schedule for the chain of lakes. Orange County is committed to implementing due diligence and performing everything within its control to advance these and other surface water AWS projects; however, development of surface water supply projects will require more time than originally estimated by the water management districts. The specific surface water AWS projects included as potential components of Orange County s Work Plan are discussed further as part of the capital improvement work plan below Regional Cooperation and Interlocal Agreements Orange County faces a certainty that future expansion of its water supplies will be increasingly challenging and expensive. A major challenge for Orange County has been the natural tendency of utilities to compete for the limited available supplies of groundwater and surface water. This type of win/lose competition for limited resources leads to protracted litigation and may prevent utilities from developing cost-efficient and synergistic solutions. Real progress has been made by east-central Florida utilities by entering into formal agreements to cooperate and seek equitable regional water supply solutions that include interconnections between their systems, development of AWS sources, and sharing of costs between all parties. As part of OCU s most recent SFWMD WUP, and as part of the County s participation in surface water AWS projects, it has become apparent that this type of regional cooperation can be critical to the success of a project. OCU s recent SFWMD WUP renewal process resulted in the formation of the STOPR (St. Cloud-TWA-OCU-Polk County Utilities-RCID) Group, which collaborated to complete their WUP applications to the SFWMD. The utilities found that the voice of the unified Group was more effective than the sum of the voices of the individual utilities. The STOPR Group has gone on to track legislative issues and perform compliance requirements together. Members of the STOPR Group and earlier CROT (City of Cocoa-RCID- OCU-TWA) Group, along with OUC, are currently in the process of forming a Central Florida Water Planning Group as the next collaborative regional group focused on addressing future water supply needs of the region. Orange County has helped facilitate these cooperative efforts and will continue to be a leader in the facilitation of regional utility cooperation regarding water supply. 14

19 Furthermore, Orange County coordinates extensively and effectively with other local governments, regulatory agencies, and utility providers to achieve local and regional objectives regarding the cost-effective and reliable provision of utility service while protecting the natural environment. A detailed description of the County s coordination approach and a list of policies are provided in the Intergovernmental Coordination Element of the Orange County CPP. The Intergovernmental Coordination Element has been significantly expanded as part of the recent CPP amendment process resulting from the County s 2007 Evaluation and Appraisal Report. With regard to potable water, wastewater, and reclaimed water service, Orange County maintains the following main types of agreements, and continually reviews/seeks opportunities to update or create new agreements: Territorial agreements, defining utility service areas (Potable Water Policy PW1.6.1; Intergovernmental Coordination Policies ICE1.3.7 and ICE1.5.4) Wholesale service agreements, providing for wholesale or emergency water supply, wastewater, or reclaimed water service (in one or both directions) between OCU and other utility providers (Intergovernmental Coordination Policies ICE1.5.4 and ICE1.5.10) Regional cooperative agreements, for a variety of mutually beneficial endeavors, such as investigating alternatives, combining resources, or developing new or expanded regional sources and facilities (Potable Water Policies PW and PW3.2.3; Intergovernmental Coordination Policies ICE1.5.1 and ICE1.5.10) Lists of the existing territorial and wholesale agreements between OCU and other utility service providers are provided in attached Appendix A and Appendix B. In addition, regional agreements are critical for the future cost-effective and environmentally responsible implementation of water resource management methods and development of traditional and alternative supplies in the fast-growing east-central Florida region. Orange County currently maintains the following key regional cooperative agreements: Water Conserv II Regional Reuse System Agreement, a cooperative agreement between Orange County and the City of Orlando, joint owners of this largest reuse project of its kind (agricultural irrigation) in the world. This agreement was executed in 1983, with no specified end date. (Supported by Potable Water Policy PW3.2.4 and Intergovernmental Coordination Policy ICE1.5.11) Curtis H. Stanton Energy Center Reclaimed Water Service Agreement, an agreement for OCU to provide a significant volume of reclaimed water to OUC for cooling at OUC s power generation facility in east Orange County, offsetting the need to use potable water for this purpose. This agreement was originally signed in 1984, and most recently in OCU and OUC continue to negotiate updates to this agreement (which is expected to remain in force for long duration). Eastern Regional Reclaimed Water Distribution System Agreement (SJRWMD DWSP Project Number 25), an agreement for interconnected reclaimed water reuse distribution facilities at a large regional scale in east Orange County and Seminole County. Led by the City of Orlando, partners to the agreement include Orange County, Seminole County, the City of Oviedo, the University of Central Florida, and OUC. Orange County signed this agreement with the City of Orlando in 2008; it has a duration of 50 years, with automatic 10-year renewals unless either party chooses to end the agreement. 15

20 CROT Interlocal Agreement for a Study to Evaluate Potential Regional Water Resources Projects, between the City of Cocoa, Reedy Creek Improvement District, Orange County, and Tohopekaliga Water Authority. The agreement was signed in 2004 and does not have a specified end date. This agreement has more recently evolved into the regional STOPR group collaboration. STOPR Cost Sharing and Compliance Coordination Memorandum of Agreement, between the City of St. Cloud, Tohopekaliga Water Authority, Orange County, Polk County, and Reedy Creek Improvement District for collaboration in implementing water resource monitoring and compliance requirements of their jointly issued water use permits from the SFWMD. The agreement was signed in 2007 and has a duration of 20 years. STOPR/SFWMD Memorandum of Agreement Regarding Water Supply Reservoir Planning and Development, an agreement between the five STOPR members and the SFWMD to explore opportunities to jointly develop a water supply source and reservoir within the Kissimmee Basin. The term of this agreement is 2007 through SJR/TCR Preliminary Design Study Agreement, a cost sharing agreement executed in 2005 by the City of Cocoa, Orange County, City of Titusville, Tohopekaliga Water Authority, East Central Florida Services, and OUC to prepare a Preliminary Design Report and Environmental Information Document/Statement for the regional St. Johns River/Taylor Creek Reservoir Surface Water AWS Project (DWSP Project Number 12). The term of this agreement is from 2005 through To ensure water supply source and facility concurrency, continue improvement of water resource management techniques, and facilitate development of cost-effective and environmentally responsible water sources and facilities, Orange County will continue to implement the following policies regarding interlocal coordination and regional cooperation: Consult with all applicable water suppliers, including internal coordination among Orange County Departments, to determine if adequate water supplies will be available to serve development in unincorporated Orange County (Future Land Use Policy FLU8.6.1; Potable Water Policy PW3.3.3) Coordinate with and seek to maintain, enhance or establish interlocal agreements with other municipalities that are provided potable water, wastewater, or reclaimed water service by OCU, and with other utilities that provide service to Orange County, in order to understand and address existing and future needs and confirm service provision commitments (Intergovernmental Coordination Policies ICE1.2.4, ICE1.3.7 and ICE1.5.4) Work closely with the water management districts to support their regional water supply planning and environmental stewardship goals (Potable Water Policies PW1.2.12, PW3.2.3, PW3.3.1, PW3.3.2, and multiple policies under Objective PW2.2; Wastewater Policies WW3.2.1, WW3.2.3 and WW3.3.1; numerous policies throughout the Intergovernmental Coordination Element) Coordinate with and continue to seek partnership/interlocal agreement opportunities with state agencies, local governments, and utilities to cooperatively study and develop feasible AWS projects (Potable Water Policies PW3.2.1 and PW3.2.3) 16

21 Maximize the beneficial use of reclaimed water to help offset the demand for potable water (Potable Water Policies PW3.2.2 and PW3.2.4; Wastewater Policies WW1.3.1, WW3.2.1 and WW3.2.2) Summary of Projected Future Water Needs and Sources Orange County plans to optimize and integrate the use of feasible water resource options to satisfy its projected water demands during the planning horizon. The County will coordinate with the water supply providers to maximize the efficient use of existing potable water and reclaimed water facilities via management techniques that can enhance the source of supply, sustain water resources and related natural systems, and optimize water supply yield. Available techniques include system interconnections, reclaimed water reuse, aquifer recharge, water conservation, and ASR. Through 2020, the County s planned sources primarily consist of increased use of reclaimed water for irrigation, additional efficient use of Floridan aquifer groundwater, and diligent pursuit of the development of new surface water AWS supplies. The planned sources of water and projected future supplies that will be available are summarized in attached Table 6 for the two major suppliers serving unincorporated Orange County. Supplemental information for OCU (the largest provider) is attached as Table 6A, with an annual breakdown and surplus/deficit computations. 17

22 3 CAPITAL IMPROVEMENT WORK PLAN 3.1 Overview Capital improvements to public, private and regional potable water and reclaimed water facilities operated by many of the providers serving unincorporated Orange County will be necessary during the planning period to accommodate future demands and to support and implement the water supply source strategy described above. Capital improvements to OCU-operated facilities, both those solely under the control of OCU and those regional cooperative AWS projects in which OCU is working collaboratively with other agencies, will play the most significant role in overcoming projected deficits within the growth areas of Orange County. In addition, several of the other providers within the County, most significantly OUC and the City of Orlando, will have to expand their independent or cooperative facilities. OCU maintains a detailed, financially feasible capital improvement program for water, wastewater, reclaimed water, and solid waste facilities, which is updated on a continual basis. All key projects from OCU s program are included in Orange County s 5-year schedule of capital improvements, adopted as part of the Capital Improvement Element of the County s CPP. Detailed information on funding sources, financial feasibility, and annual budget allocations is provided in the Capital Improvement Element, and a summary list of OCU s relevant projects is included as Appendix D to this Work Plan. As required by recent legislation, Orange County s Capital Improvement Element and 5-year schedule of capital improvements will be amended on an annual basis and will maintain consistency with this Work Plan. The results of Orange County s most recent revenue sufficiency analysis indicate that the funding of capital improvement projects over the planning period can be accomplished through rate revenue, connection fees, and debt funding, which will require implementation of the system s 3-percent automatic rate provision from time to time to meet debt service coverage requirements. In addition, some of the AWS projects included in this Work Plan will be partially funded through cooperative grants from the water management districts, other state agencies, or other utilities participating in regional efforts. Listed by provider, the key planned capital improvement projects needed to provide adequate future water supply capacity within unincorporated Orange County are described below. The listed projects focus on development of new and expanded water sources (groundwater, reclaimed water, surface water) and their treatment facilities. Projects to increase the capacity of water distribution and wastewater collection systems are not discussed in this section as they are too numerous to list; however, Orange County does include these capacity projects in its annual capital improvement program update to keep the systems in compliance with OCU hydraulic level of service standards. 3.2 Orange County Utilities To meet projected demands within the 10-year planning horizon, OCU will: Expand and optimize its traditional groundwater supply facilities Continue to implement, and increase as feasible, its conservation initiatives listed above 18

23 Expand its reclaimed water facilities to reduce demand for potable water Diligently pursue development of new AWS sources, alone and in conjunction with other providers Continue to investigate additional alternatives Promote regional cooperation and joint solutions OCU will implement the traditional, reclaimed and alternative capital improvement projects described below during the planning period of this Work Plan. Attached Table 7 summarizes the system capacity increases anticipated as a result of these capital projects. These projects will overcome projected supply deficits for demands within the entire OCU service area, most of which falls within unincorporated Orange County. Unit ( org ) project numbers are listed as appropriate for direct cross-reference with information in the OCU capital improvement program and in the County s 5-year Capital Improvement Schedule (CIS) (see Appendix D and Orange County s Capital Improvement Element). In addition, cross-references are provided between these capital projects and those identified in the current SJRWMD and SFWMD regional water supply plans. The current 5-year CIS includes detailed project funding data for the Fiscal Year (FY) 2008 through FY 2013 period. Beyond the 5-year planning horizon, OCU will need to develop additional AWS projects to accommodate future demands. Early implementation phases (e.g., preliminary design and permitting) and capital improvement funding for these projects have already begun so that actual construction and availability of water supply can occur as soon as feasible. For the AWS projects currently in the OCU Work Plan and Capital Improvement Program (CIP) budget, Appendix D includes an estimated breakdown of committed or planned funding by fiscal year and project phase. Although not yet committed, funding for the second 5 years of the Work Plan planning period (FY 2014 through FY 2018) is included where it has been estimated as requested future dollars in the OCU CIP budget. As an additional point of note in the County s capital improvement work plan, the sources of water for the AWS projects may be located in areas of the County (e.g., eastern Orange County, intake along the St. Johns River) that may be remote from the location of the demands to be met by these new supplies. To facilitate distribution of future supply throughout the OCU service areas, three additional projects (SSA-ESA Water Main projects: CIS , , and ) are currently included in the OCU CIP budget for FY 2008 through FY 2013 (see Appendix D) to interconnect the OCU South and East Service Areas. As previously mentioned, because the OCU South, Southwest, and West Service Areas are already interconnected, construction of the SSA-ESA water main will effectively provide complete interconnection of the OCU water distribution facilities, as needed to incorporate the new AWS supplies Traditional Water Supply Projects OCU will implement the following groundwater supply capital improvement projects, which will increase WSF treatment capacity by approximately 37.8 mgd, AADF and wellfield capacity by approximately 31.6 mgd, AADF during the planning horizon. Western Regional WSF/Wellfield Phase III Expansion, planned for construction by 2010, will increase treatment capacity by another 7.0 mgd, AADF. This expansion will also 19

(CIS 1450 and 1508) Reclaimed Water Supply Projects As feasible, OCU will implement the following reclaimed water capital improvement projects, which will increase the reclaimed water supply available to meet non-potable demands during the planning horizon. Northwest WRF Phase III Expansion, planned by 2012, will provide treatment capacity increase from 7.5 to mgd, AADF. (West Service Area, CIS 1435) Northwest WRF RIB System Expansion, with additional capacity of 0.4-mgd, AADF, planned to be completed by July (West Service Area, CIS 1496, CUP #3317 Condition 29) Northwest Reclaimed Water Project (SJRWMD DWSP Project Number 38), includes reclaimed water storage, pumping, and distribution system construction for public access reuse, with an anticipated capacity of approximately 3 mgd, AADF, to be constructed by (West Service Area, CIS 1496, CUP #3317 Condition 27) Southwest WRF Phases I & II, planned to be constructed simultaneously by 2015, for a total treatment capacity of 10.0 mgd, AADF. Phase II provides additional capacity to receive flow diversion from the South Service Area. (Southwest Service Area, CIS 1507) 20

25 Southwest Service Area Reclaimed Water System Expansion (a KBWSP Project), an estimated 5.0 mgd, AADF reuse distribution system, planned to be constructed between 2008 and 2015 (CIS 1542, CUP #3317 Condition 27). The reuse system expansion includes the following two related projects listed in the KBWSP, among others: CR 535 Reclaimed Water Main from Reams to Grand Cypress Golf Course. (CIS 1542) Horizon West Primary Reuse Transmission Mains to Villages H and I. (CIS 1542) South WRF Phase V Expansion, planned by 2012, will increase treatment capacity from 43.0 to 56.0 mgd, AADF. (South Service Area, CIS 1555, a KBWSP Project) South Service Area Reuse System Expansion, expected to add roughly 5.0 mgd, AADF to the existing capacity of the system in the South Service Area, constructed during the planning horizon (CIS 1411, CUP #3317 Condition 27, a KBWSP Project). The reuse system expansion is related to the following specific projects listed in the KBWSP, among others: 20-Inch Reclaimed Water Main: CR535 to John Young Parkway (JYP) Vistana to JYP. (CIS 1411) Universal South Reuse Transmission Main. (CIS 1411) JYP Improvements Phase II: Town Center Blvd to Sand Lake Road. (CIS 1411) Orangewood Blvd Reclaimed Water Main. (CIS 1411) Hidden Springs Reclaimed Water Storage and Repump Facility. (CIS 1411) Holden Heights Phase 4 Wastewater Collection System (Lake June), includes the connection of new customers currently using septic tanks to make an estimated 1 mgd, AADF of additional reclaimed water available. (CIS 1505) Eastern WRF Phase IVC Expansion, planned to be constructed by 2010, will increase treatment capacity from 19.0 to 21.0 mgd, AADF. (East Service Area, CIS 1538) Eastern WRF Phase V Expansion, planned to be constructed by 2012, will increase treatment capacity from 21.0 to 24.0 mgd, AADF. (East Service Area, CIS 1538) Eastern WRF Re-Rating, planned to be constructed by 2014, will increase treatment capacity from 24.0 to 27.8 mgd, AADF. (East Service Area, CIS 1538) Eastern Regional Reclaimed Water Distribution System (a.k.a., Eastern Orange and Seminole Counties Regional Reuse System). OCU is participating in this project, led by the City of Orlando, to develop a 20-mgd interconnected, regional reclaimed water distribution system. Construction should be completed by (East Service Area, DWSP Project Number 25, also a KBWSP Project) Southeast Reclaimed Water System Expansion Project, will be constructed throughout the planning horizon to distribute reclaimed water to meet reuse irrigation demands in the East Service Area, estimated to be as much as 9 mgd, AADF by (CIS 1483, CUP #3317 Condition 27, DWSP Project Number 39) Eastern WRF Public Access Reuse Storage and Pumping Facility, related to the above project, will be completed in (CIS 1483, CUP #3317 Condition 27, a KBWSP Project) 21

26 East Service Area Reclaimed Water Storage and Repump Facility (Moss Park RW Storage and Repump). (CIS 1483, a KBWSP Project) In addition, Orange County will continue to coordinate with the City of Orlando to evaluate and implement necessary improvements and expansion of the Water Conserv II reclaimed water system, which is jointly owned by the County and the City Alternative Water Supply Projects As feasible and permittable, OCU will implement the following surface water AWS capital improvement projects, which will increase potable water supply capacity by approximately 30 mgd, AADF or greater. St. Johns River/Taylor Creek Reservoir Water Supply Project, an estimated 50 mgd, AADF surface water potable supply project (CIS 1550; CUP #3317 Condition 24; WUP # W Condition 25; DWSP Project Number 12; also a KBWSP Project). OCU is participating collaboratively in this regional water supply development project with five other central Florida potable water suppliers: OUC, East Central Florida Services, and Tohopekaliga Water Authority (who all provide some water in unincorporated Orange County); and the City of Cocoa and City of Titusville. The exact supply volume distribution among suppliers is yet to be finalized, but it is anticipated that OCU s share will be at least 10 mgd, AADF. The project is currently in the preliminary design phase. Based upon current progress, it is estimated that under a best-case scenario this project will begin producing water by 2015 or Estimated total capital cost is approximately $220 million (based on the SJRWMD DWSP), funding for which will be split among the six suppliers, with additional cooperative funding from the State. Funding is currently committed in the OCU capital improvement budget (CIS 1550) for various phases of the project (refer to the 5-Year CIS in the Capital Improvement Element). Kissimmee River Basin (Lake Tohopekaliga) Potable Water Supply Project, an estimated 25 mgd, AADF surface water potable supply project (WUP # W Condition 25; a KBWSP Project). OCU is participating collaboratively in this regional water supply development project, currently at the conceptual stage, with several other central Florida potable water suppliers. The final number of utility partners, exact supply available, and distribution among suppliers is yet to be determined, but it is anticipated that OCU s share will be 10 mgd, AADF. Currently, it is estimated that this project will begin producing water circa Funding for the project will be split among the suppliers, with additional cooperative funding from the State. St. Johns River at State Road 46 Water Supply Project (DWSP Project Number 64), an estimated 63 mgd, AADF surface water potable supply project, is currently in the conceptual development phase. This project may be constructed outside of the planning horizon addressed by this Work Plan (post-2020). OCU is participating collaboratively to develop this regional water supply development project with several other central Florida potable water suppliers. The SJRWMD has facilitated several regional coordination meetings for this project. OCU s potential share of the yield from this project is not yet known. Aquifer Storage and Recovery (ASR) Pilot Project. An ASR test well is being installed in east Orange County at the EWRF property, as part of a collaborative study with the 22

27 SJRWMD (CIS 1550). Initial cycle testing will use OCU potable-quality water for storage in the Floridan aquifer and subsequent recovery. Based on the results of the cycle testing, a future full-scale ASR well system may be a feasible component of the County s alternative water supply strategy. Southeast Reuse System Augmentation Project would have provided up to 8 mgd, AADF of surface water augmentation to the OCU East and South Reclaimed Water Service Area reuse systems (CIS 1550, a KBWSP Project). However, this project has been removed from Orange County s Work Plan because the permit application was denied by the SFWMD. Southwest Reuse System Augmentation Project, a potential future surface water project to provide backup supply to the OCU Southwest Service Area reuse distribution system, estimated at 2.0 mgd (a KBWSP Project). 3.3 Orlando Utilities Commission To meet projected demands within the 10-year planning horizon throughout its entire potable water service area, OUC will: Continue to utilize its traditional groundwater supply facilities Continue to implement the conservation plan included in its SJRWMD CUP Utilize City of Orlando reclaimed water to meet a portion of the non-potable demands in OUC s service area Develop a new regional AWS surface water source, in conjunction with other providers A portion of OUC s total potable water supply sources will be applied within unincorporated Orange County. OUC will implement the following alternative water supply (including surface water development and reclaimed water system expansion) capital improvement projects to increase potable and non-potable water source and facility capacity during the planning horizon. St. Johns River/Taylor Creek Reservoir Water Supply Project, cooperative project among OUC, Orange County, Tohopekaliga Water Authority, City of Cocoa, City of Titusville, East Central Florida Services, SJRWMD and SFWMD, adds up to 40 mgd average daily flow alternative water supply project, estimated cost of $220 million. Eastern Regional Reclaimed Water Distribution System (ERRWDS), cooperative project among City of Orlando, Orlando Utilities Commission, Orange County, Seminole County, City of Oviedo and University of Central Florida, adds 20 mgd of reclaimed water capacity, estimated cost of $51 million to be constructed between 2004 and Project RENEW, cooperative project among the City of Orlando, Orlando Utilities Commission, and Project RENEW reclaimed water customers in west Orange County, to deliver 9.2 mgd reclaimed water from Iron Bridge WRF to west Orange County where there is a deficit of reclaimed water capacity, estimated cost $56.8 million to be constructed Other OUC potable water system capital improvement projects include: 23

28 Production Plant Modifications and Equipment, estimated cost $1.5 million to be constructed Well and High Service Pump Rehabilitation estimated cost $1.75 million to be constructed Pipeline Renewal and Replacement estimated cost $7.5 million, constructed System Reliability Upgrades, estimated cost $2.35 million to be constructed Ozone Generator Replacement, estimated cost $4.05 million to be constructed Renewal and Replacement, estimated cost $12 million to be constructed Developer Initiated Projects, estimated cost $1.9 million to be constructed Future Projects, estimated cost $2.1 million to be constructed Constructed Water Plant, estimated cost $6.8 million to be constructed Southeast Plant Expansion, estimated cost $500 thousand to be constructed 2011 Loop Closures/Tools and Equipment, estimated cost $2.13 million, constructed Back Flow Devices, estimated cost $2.5 million to be constructed Donated Water Plant, estimated cost $17.6 million to be constructed Interagency Projects, estimated cost $8.6 million to be constructed Other Providers in Unincorporated Orange County Capital improvement work plan data for other utility providers serving unincorporated Orange County were not readily available. Such data however do not represent a critical component of Orange County s CPP as these providers serve only a very small percentage of the total water demand in the unincorporated areas. Orange County municipalities, within which many of these providers deliver most of their water, incorporate relevant data on water supply capital improvement projects in their water supply facility work plan amendments. 24

43 APPENDICES Orange County Water Supply Facilities Work Plan

44 APPENDIX A Potable Water Supply Facilities Serving Unincorporated Orange County In support of this Work Plan, an inventory of potable water facilities was completed for those public and private utilities providing potable water service within unincorporated Orange County. This appendix presents additional information on the existing facilities and related consumptive and water use permits for these potable water service providers, which include the following significant utilities: Orange County Utilities Orange County Research and Orlando Utilities Commission Development Authority Apopka (City of) (Central Florida Research Park) Aqua Utilities Florida Taft Water Association East Central Florida Services Tohopekaliga Water Authority Mount Dora (City of) University of Central Florida Oakland (Town of) Wedgefield Utilities Ocoee (City of) Winter Garden (City of) Southlake Utilities Winter Park (City of) Zellwood Water Users Summaries of the existing potable water supply permit allocations associated with the abovelisted utilities are presented in the data and analysis section of the Orange County Work Plan (Table 2). In addition, detailed existing facility capacities are summarized in Work Plan Table 1 for Orange County Utilities and the Orlando Utilities Commission, which are the two largest providers and represent nearly all of the public supply in unincorporated Orange County). Four other utilities not listed above Reedy Creek Energy Services (the utility provider for Reedy Creek Improvement District), the City of Casselberry, the City of Maitland, and the Town of Eatonville provide potable water service within Orange County. These utilities have potable water service areas, however, which remain within their jurisdictional boundaries and do not contribute to the supply within unincorporated Orange County. For this reason, it is not necessary to address these providers as part of Orange County s Work Plan. In addition to the above providers, several very small utilities (e.g., Lake Ola Homeowners, Clarcona Resorts Condominium Association, Valley Mobile Home Park, etc.) provide limited potable water service within unincorporated Orange County. These small providers, however, have no potential for growth within their service areas and are therefore not addressed explicitly in the Work Plan. The potable water suppliers operate numerous water supply facilities, which are described in more detail below. All of these potable water providers currently use the Floridan aquifer as their primary source of water supply. A-1

45 ORANGE COUNTY UTILITIES (OCU) Facilities The Orange County Utilities (OCU) Department is the largest potable water provider in unincorporated Orange County. The Water Division provides the drinking water supply for much of unincorporated Orange County, as well as for the Town of Windermere and portions of several other municipalities in Orange County, through the operation and maintenance of water treatment systems, transmission systems, and distribution systems. OCU currently owns and operates 11 water treatment facilities, five of which are located in the SJRWMD and six in the SFWMD. Potable water is currently supplied to these treatment facilities by 42 active wells completed in both the upper and lower production zones of the Floridan aquifer. OCU s responsibility is divided across four potable water service areas (Figure A.1). The total average potable water produced by OCU in 2005 was approximately 60 million gallons per day (mgd), serving the needs of a residential population of roughly 310,000, plus a significant number of commercial businesses such as hotels. Figure A.1. Orange County Utilities Potable Water Service Areas (Source: Orange County Utilities) A-2

46 OCU currently obtains its potable water supply from groundwater of the Floridan aquifer through wellfields associated with the following existing water supply facilities (WSFs): SJRWMD Facilities SFWMD Facilities Eastern Regional WSF Hidden Springs WSF Econ WSF Cypress Walk WSF Western Regional WSF Hunters Creek WSF Oak Meadows WSF Meadow Woods WSF Lake John Shores WSF Orangewood WSF Vistana WSF OCU s active production wells tap the Lower production zone of the Floridan aquifer at the Western Regional, Oak Meadows, and Hidden Springs WSF wellfields, while the remainder of the County s supply wells tap the Upper production zone of the Floridan aquifer. Wells and well pumps are used to withdraw water from the Floridan aquifer, as permitted by the SJRWMD and SFWMD. A summary by service area of the number and capacity of existing OCU water supply wells is provided in Table A.1. Table A.1. Existing Orange County Utilities Water Supply Wells East Service Area (1) West Service Area South Service Area Southwest Service Area (2) Active Wells Inactive Wells Abandoned Wells Active Well Peak Capacity (mgd) (1) Includes Eastern Regional WSF wellfield Phase 2B expansion (additional wells ER7-ER12), recently constructed. (2) Future wellfields, including CR535 and Malcolm Road, are planned for this growth area of Orange County. Currently, the Southwest Service Area is served through interconnects to other OCU service areas or by wholesale agreement with the Tohopekaliga Water Authority. The Southwest Service Area does not have operational wells or facilities; however, the County Road 535 (CR535) (a.k.a., Horizon West) WSF (permitted by the SFWMD) is currently under design and associated wells have been constructed. In addition, the Malcolm Road wellfield and WSF (permitted by the SJRWMD) is planned to serve this area. Permits OCU currently holds one primary SJRWMD consumptive use permit (CUP) and two SFWMD water use permits (WUPs) for potable water supply: SJRWMD CUP#3317: Covers the East and West Service Areas and a portion of the Southwest Service Area (Malcolm Road WSF), 55.7 mgd annual average allocation, expires December 13, 2026 A-3

In addition, the OCU permits include, as specific conditions, several requirements regarding the use of reclaimed water and development of alternative water supplies, as described below. Under SJRWMD CUP #3317, OCU is required to: Provide a minimum of 28.4 mgd, AADF by 2011; 34.6 mgd, AADF by 2016; and 41.8 mgd, AADF by 2026 of reclaimed water across the OCU service areas to meet irrigation water demands, in accordance with the following reuse implementation schedule by source facility (Condition 27): 4.3 mgd, AADF by 2016 and 5.7 mgd, AADF by 2026 from OCU s Eastern Water Reclamation Facility (WRF) 0.8 mgd, AADF by 2016 from OCU s Northwest WRF 29.5 mgd, AADF by 2016 and 35.3 mgd, AADF by 2026 from OCU s Southwest, Cypress Walk, and South WRFs combined Provide 0.3 mgd, AADF of aquifer recharge from the Old Winter Garden Road RIB Project and 0.4 mgd, AADF of aquifer recharge from the Northwest WRF RIB Expansion Project (Condition 29) Develop the St. Johns River/Taylor Creek Reservoir Project, or one or more other alternative water supply (AWS) projects, to supply no less than 10 mgd, AADF of water to meet that portion of OCU s public supply demands not met by groundwater or reclaimed water allocations authorized by the permit. The facility must be constructed and able to provide at least 10 mgd of water by December 31, 2013 (Condition 24) Under SFWMD WUP # W, OCU is required to: Produce a quantity of non-potable water for land application generally consistent with the following projections (Condition 29): 28.5 mgd, AADF by mgd, AADF by mgd, AADF by 2013 A-5

49 Develop a Kissimmee River Basin surface water project, or one of more other AWS projects (in addition to the 10-mgd AWS project required by the SJRWMD CUP), to meet a minimum of another 10 mgd of OCU s public water supply demands not met by the groundwater allocations under the SFWMD permit. This facility must be constructed and able to provide at least 10 mgd of water by July 2014 (Condition 25) Agreements OCU maintains the following three primary types of potable water-related agreements: Territorial agreements, defining utility service areas Wholesale service agreements, providing for wholesale or emergency water service (in one or both directions) between OCU and other utility providers Regional cooperative agreements, for mutually beneficial initiatives, such as investigating alternatives, combining resources, or developing new or expanded regional sources and facilities Orange County s policies and initiatives regarding territorial and joint planning area agreements are described in significant detail in the Intergovernmental Coordination Element of the County s Comprehensive Policy Plan. OCU maintains territorial agreements with all the other major potable water providers within Orange County, and some of those in neighboring counties that may have facilities or customers in Orange County, including the following: Orlando Utilities Commission (OUC) City of Apopka City of Cocoa Econ Utilities (Wedgefield Utilities / Utilities, Inc.) City of Maitland City of Mount Dora City of Ocoee Reedy Creek Improvement District Southlake Utilities Tohopekaliga Water Authority (City of Kissimmee) University of Central Florida City of Winter Garden City of Winter Park OCU has a number of potable water service interconnects with other utility systems. While most of these interconnects are for emergency situations, a few potable water agreements are in place between Orange County and other entities allowing Orange County to purchase water if needed. Table A.4 presents a summary of current wholesale and interim agreements. Historically, OCU has purchased minor volumes of wholesale water from these utilities in areas where OCU water distribution infrastructure was not yet in place. A-6

50 Table A.4. Orange County Potable Water Service Agreements Entity Tohopekaliga Water Authority City of Winter Garden Orlando Utilities Commission (OUC) City of Winter Park Capacity / Conditions Tohopekaliga Water Authority can provide interim or wholesale water service to OCU in portions of the Southwest Service Area Winter Garden can provide wholesale water service to the Magnolia Woods and Partlow Acres subdivisions in the West Service Area OUC can provide wholesale or interim water service to the Corrine Terrace, Daetwyler Shores, Lake Conway, and Kilgore areas of the OCU East and South Service Areas Winter Park can provide wholesale or interim water service to Bradford Cove, Hunters Ridge Apartments, Sutton Ridge, and University Forest in the OCU East Service Area In addition to territorial and wholesale service agreements, regional cooperative agreements are critical for the future cost-effective and environmentally responsible implementation of water resource management methods and development of traditional and alternative potable water supplies in the fast-growing east-central Florida region. As described in Section of the Work Plan, Orange County currently maintains the following key regional cooperative agreements related to potable water: CROT Interlocal Agreement for a Study to Evaluate Potential Regional Water Resources Projects, between the City of Cocoa, Reedy Creek Improvement District, Orange County, and Tohopekaliga Water Authority STOPR Cost Sharing and Compliance Coordination Memorandum of Agreement, executed in 2007 between the City of St. Cloud, Tohopekaliga Water Authority, Orange County, Polk County, and Reedy Creek Improvement District for collaboration in implementing water resource monitoring and compliance requirements of their jointly issued water use permits from the SFWMD STOPR/SFWMD Agreement Regarding Water Supply Reservoir Planning and Development, an agreement between the five STOPR members and the SFWMD to explore opportunities to jointly develop Kissimmee Basin water supply facilities SJR/TCR Preliminary Design Study Agreement, a cost sharing agreement executed in 2005 by the City of Cocoa, Orange County, City of Titusville, Tohopekaliga Water Authority, East Central Florida Services, and OUC to prepare a Preliminary Design Report and Environmental Information Document/Statement for the regional St. Johns River/Taylor Creek Reservoir Surface Water AWS Project ORLANDO UTILITIES COMMISSION (OUC) Facilities Orlando Utilities Commission (OUC) is the municipal utility of the City of Orlando that provides water, electric and chilled water services. OUC s water service area (Figure A.2) measures approximately 200 square miles which includes the Cities of Orlando, Edgewood and Belle Isle plus large portions of unincorporated Orange County. A-7

51 Figure A.2. Orlando Utilities Commission Potable Water Service Area A-8

52 There are eight water supply/treatment facilities within the OUC water service area. Each facility includes wells, ozone generating equipment, ozone contact tanks, chemical feed equipment, ground storage reservoirs, high service pumps, control equipment, and emergency power facilities to run the plant in the event of an extended power outage. The only constituent in the raw water that requires treatment is hydrogen sulfide, a gas with an offensive odor that is easily removed by the ozone treatment equipment. OUC s water supply/treatment facilities are relatively new as a result of a major construction program that took place during the period. The program converted the hydrogen sulfide treatment process from aeration to ozone which produces a higher quality finished water. In addition to installing new ozone treatment equipment at five existing plants (Pine Hills, Kirkman, Navy, Conway and Sky Lake), the plants were refurbished, upgraded and modernized. In addition, the capacity at some was increased. Three new water supply/treatment facilities utilizing ozone treatment were constructed (Southwest, Lake Highland and Southeast). Five older aeration plants were abandoned and demolished to reduce the number of facilities. OUC has three emergency interconnects with Orange County Utilities which provide emergency sources of water in the event one utility unexpectedly experiences extensive loss of supply sources or treatment facilities. The water can flow either way through an emergency interconnect, depending on which utility needs the water. They are intended to be used only in an emergency and require the cooperation of both utilities to activate them during an emergency. There are approximately 1,705 miles of transmission/distribution pipes ranging in size from 2 inches to 48 inches. One of the functions of this network is to interconnect all the water supply/treatment facilities with each other. There are three water storage tanks connected to the transmission/distribution system. These tanks help maintain minimum acceptable pressure in the pipe network and supply water into the pipe network during peak demand periods. Permits OUC entered into an interagency agreement with SJRWMD and SFWMD in May 2004 as part of its CUP renewal process. Under this agreement, SFWMD delegated to SJRWMD all of its authority to issue a single, consolidated CUP to OUC. SJRWMD issued CUP # 3159 in May It is a 20 year duration permit, scheduled to expire in October In addition to authorizing a consolidated CUP, the interagency agreement allows SJRWMD to issue well construction and ERP permits to OUC, and to enforce OUC s CUP throughout the 20 year duration of the permit. OUC s permit allocates mgd of groundwater from the Floridan Aquifer in The allocation increases annually each year with 95 mgd in 2004 to mgd in From 2016 to 2023, the maximum annual system-wide allocation is limited to mgd. In addition to the mgd system-wide limitation on groundwater withdrawals, the CUP limits withdrawals at each individual water supply/treatment facility. This allocation is less than the potable water demands that OUC estimates it will need by In addition, OUC s permit includes reclaimed water use and conservation requirements as specific conditions: A-9

53 OUC is required to use 11.1 mgd of reclaimed water to supply landscape irrigation needs within its service area. OUC does not own water reclamation facilities that produce reclaimed water, but has an agreement with the City of Orlando to utilize this reclaimed water. OUC is also required to implement a regional reclaimed water project, which has been named Project RENEW. Project RENEW will redirect 9.2 mgd of reclaimed water from the area served by the City of Orlando s Iron Bridge Water Reclamation Facility, where there is excess supply, to northwest and west Orange County, where it is in short supply. As part of the CUP application process, OUC submitted a conservation plan in accordance with SJRWMD rules. The plan identifies a number of measures that OUC will employ to conserve water in the future. OUC will rely largely on water rates and education to encourage customers to avoid wasteful uses of water in the future, and to use less water on a per capita basis than they have in the past. OUC adopted a waterconserving rate structure in Monthly water usage in excess of 30,000 gallons is billed at $2.93 per 1,000 gallons, whereas a customer who uses 3,000 gallons or less is billed at $0.80 per 1,000 gallons. OUC is prepared to continue to use conservation rates in the future, as necessary, to curtail wasteful water usage practices, and to achieve the conservation goals dictated by the CUP. Another tool that OUC has used in the past, and will continue to rely on in the future, is water conservation education. OUC has produced television, radio, written and website material to urge customers to reduce the quantity of water used for irrigation by providing them with actions they can take to effectively reduce water usage without risking damage to lawns and landscape plants. In addition to the permit conditions, OUC has legal obligations under two settlement agreements. These agreements concluded several months of litigation brought on by permit challenges filed by Orange County and Lake County in October One agreement was signed by OUC, Orange County, SJRWMD and SFWMD. It requires that OUC develop at least 5 MGD of water by 2013 from an alternative supply source, such as Taylor Creek Reservoir, the St. Johns River, or other sources acceptable to the SJRWMD. The agreement anticipates that OUC will pursue alternative water supply development jointly with Orange County, which has a similar obligation under the agreement. OUC also agreed that it would not challenge permits that Orange County has pending with both SJRWMD and SFWMD. The second agreement was signed by OUC and Lake County. Under this agreement, OUC agrees to give Lake County an option to participate in any alternative water supply development project it pursues. This will assure Lake County a place at the table as alternative water supply development is discussed in Central Florida in the future. Agreements The service area boundary was established by OUC and Orange County in May 1994 in the Amended and Restated Orlando Utilities Commission/Orange County Water Service Territorial Agreement. This 25 year agreement is intended to avoid duplication of facilities that would cause needless and wasteful expenditures, and avoid unpredictability and continual changes in utility service areas which hinder the ability to make prudent capital investment or plan for efficient system expansion. The agreement allows for changes to the territorial boundary and the A-10

54 provision of wholesale water by one party to the other. As shown in Figure A.2, OUC is surrounded on all side by the Orange County Utilities water system service area, except for a portion of the northern boundary where OUC interfaces with the City of Winter Park water utility. CITY OF APOPKA Facilities The City of Apopka s service area for its water system has historically coincided with the City s urban service area. The boundary for the service area contains approximately 68 square miles and was expanded with the acquisition of facilities from Orange County. The service area includes most of the area within the City limits, plus a large area within unincorporated Orange County. This area of unincorporated Orange County, however, is not densely populated and has only a minor amount of growth projected within the planning horizon. The City owns five Water Treatment Plants (WTPs) including two WTPs that were recently purchased from Orange County. An additional water treatment plant (Southwest) is planned for the future. The wells associated with these treatment plants are located in northwest Orange County. The drinking water source taps the Lower Floridan Aquifer. The current water distribution system, not including on-site piping at the treatment plants, consists of pipes range in diameter from 3-inch to 36-inches, fire hydrants and isolation valves. There are currently no elevated storage facilities serving the distribution system. There are a total of six ground storage tanks within the City serving the distribution system.

These developments have historically been served by the Town s water system, and all are anticipated to be built out by There are currently no centralized wastewater treatment facilities in the Town, and individual lots use onsite septic systems for wastewater disposal. Discussions are currently taking place with the City of Winter Garden to explore the feasibility of Oakland being served by the Winter Garden sewer and reclaimed water systems. In 1986, when the service area was originally permitted, the existing population served was 670. This Consumptive Use Permit was renewed twice prior to submittal of the current permit application, with an increasing population each renewal, since this is a rapidly growing area. According to the District s 2003 Water Supply Assessment, the current population of the service area is estimated at 2,414, with a projected increase in population to 5,178 within 10 years. The Town s Planning Department estimates that the future population growth will take place sooner than the estimate by the District. For the purposes of determining an allocation for the current permit, the District s population estimates were used. The Town of Oakland s water supply system consists of two Upper Floridan aquifer wells, wells B and C. Well B is completed in the upper layer of the Upper Floridan aquifer, and is a 10-inch diameter well with a depth of 494 ft. Well C is completed in the lower layer of the Upper Floridan aquifer at a depth of 800 ft, and is a 12-inch diameter well. Wells B and C are ganged A-14

58 and monitored together with a single totalizing flowmeter. In addition, the town formerly used well A, an 8-inch diameter Floridan aquifer well, which is now abandoned. All potable connections in the service area are metered, as well as several irrigation connections. There are no plans at this time to expand the well field or construct additional wells. At this time there are no available sources of reclaimed water for irrigation; however, the Town is continuing to negotiate with the City of Winter Garden to the east for reclaimed service along the Highway 50 corridor in the future. Current water use in the Town s service area is primarily indoor and outdoor household use. Approximately 2 acres of common area around the Town Hall are irrigated by the Town s water system. No other common area irrigation for parks or other areas takes place within the Town.

62 TOHOPEKALIGA WATER AUTHORITY (TWA) Facilities Established in October 2003 by a special act of the Florida legislature, the Tohopekaliga Water Authority (TWA) is the largest provider of water, wastewater and reclaimed water services in Osceola County. TWA currently serves 73,000 water, 71,000 wastewater and 10,000 reclaimed water customers in Kissimmee, Poinciana and unincorporated areas of Osceola County. In April 2007, TWA acquired Poinciana Utilities expanding the customer base by 30 percent. TWA owns and operates 20 water plants and 10 wastewater plants while maintaining 1,174 miles of water mains, 980 miles of wastewater mains, 242 miles of reclaimed water mains and 357 wastewater pump stations. TWA treats and distributes approximately 35 million gallons of potable water and reclaims 21 million gallons of wastewater each day. Under the special act, the service area of the TWA includes the City of Kissimmee and unincorporated areas of Osceola County, with the exception of Reedy Creek Improvement District and the City of St. Cloud. TWA water facilities include 20 water treatment plants consisting of wells, ground storage tanks, high service pumps and the water distribution system. TWA water facilities currently rely exclusively on groundwater from the Upper Floridan Aquifer. Water is distributed through 1,174 miles of water mains. Raw water supply wells currently pump an average of 35 million gallons per day to the 20 water treatment plants located throughout the service area. The utility is projected to serve approximately 201,605 persons in the year TWA had previously received a Water Use Permit on January 2006 with a duration of five years. Within the 2006 Water Use Permit, TWA was authorized to withdraw a maximum monthly allocation of million gallons (MG) and had an annual allocation of 9,736 MG (26.67 MG per day annual average). TWA permit included 23 existing and 10 proposed Upper Floridan Aquifer wells. With the 2007 renewal and modification of its SFWMD permit, TWA will continue potable water withdrawals from the Upper Floridan Aquifer via 37 existing withdrawal facilities and six additional withdrawal facilities. Recognizing the need to develop alternative water supplies, TWA initiated the development of a brackish water supply near Lake Cypress. Additionally, TWA is participating in discussions to develop a water supply from the Upper Kissimmee River. In conjunction, TWA continues to participate in the Preliminary Design Phase of the St. Johns River/Taylor Creek water supply project. Permits In 2007, TWA obtained renewal of its Water Use Permit. The permit renewal was processed and negotiated concurrently with permit renewals with four other utilities: St. Cloud, Orange County, Polk County and Reedy Creek Improvement District (known as STOPR Utilities). A 20 year permit was issued which restrict groundwater withdrawals after 2013 to the projected demands for that year. Water for additional demand after 2013 must by provided by alternative water A-19

63 supplies. The permit conditions established the requirement for the development of an extensive monitoring network and program that covers the service area of the STOPR Utilities. The STOPR group negotiated an interlocal agreement to establish this relationship. TWA modified and renewed Water Use Permit W for public water supply for their service area. In addition, this permit canceled and superseded previous Water Use Permit W for the Buenaventura Lakes service area. These Water Use Permits are combined under new Water Use Permit W issued by SFWMD in June 2007, which allocates 35.6 mgd (annual average) of groundwater to TWA. The permit expires in June As a condition of the current WUP, TWA is required to: Develop an alternative water supply (AWS) project that provides at least 15 mgd of water by December 31, This commitment must be met by developing alterative supplies from the Cypress Lake Brackish Groundwater Wellfield and/or the Kissimmee River Chain of Lakes Surface Water Project and/or other AWS projects. In addition, as a condition of its permit, TWA must develop an additional AWS project(s) to meet projected demands within its service area through 2027 not met by the groundwater allocation and the 15 mgd AWS project requirement. Agreements The STOPR Utilities [the City of St. Cloud, TWA, Orange County Utilities, Polk County Utilities (PCU), and Reedy Creek lmprovement District (RCID)] with permit applications pending before SFWMD proposing groundwater withdrawals from the Upper Floridan Aquifer were notified by letter dated November 3, 2006 that a preliminary determination that their applications were considered competing. Recognizing their shared interests, in December 2006, the STOPR Utilities executed an Interlocal Agreement Relating to Participation in Regional Cooperation to Pursue Water Use Permits in the SFWMD. In the STOPR Utilities' Agreement, the five utilities recognized the benefits of regional cooperation, defined a framework for such cooperation, including intent to jointly pursue their respective, competing consumptive use permit applications to meet 2013 water supply demands. One of the critical provisions of the STOPR Utilities' Agreement was the commitment to provide the SFWMD, in satisfaction of requests for additional information, with a regional transient groundwater model for cumulative impact assessment of the proposed STOPR Utilities' withdrawals. Moreover, the STOPR Utilities' Agreement indicates their intent to "...work towards and receive equitable water use permits... and to avoid administrative or judicial challenges by any Party to any other Party's water use permit..."

CITY OF WINTER GARDEN Facilities The City of Winter Garden is located in western Orange County, approximately 12 miles west of the City of Orlando on State Road 50. The City of Winter Garden occupies approximately ten (10) square miles with direct access to Lake Apopka. The Florida Turnpike and State Road 50 both run through the City s limits. The existing water and wastewater service areas encompass the entire incorporated limits of the City and several properties outside the City limits approximately 18 square miles. Winter Garden s water system was purchased by the City in The system has been improved and/or extended on several occasions since its purchase in the mid-1940s. There are three water treatment plants that provide potable water to the distribution system. Historically, the land in the City and surrounding areas was utilized mostly for citrus and farming. However, land use trends in the past ten to twenty years have shifted toward residential and commercial development. In 2005, the City provided approximately 22,174 people with potable water service. In July 1996, the City submitted an application to renew its existing Consumptive Use Permit (CUP) with a request to increase their allocations from million gallons per year (mgy) in 1996 to 1, mgy in 2006 to serve a growing population. In February 2001, the City revised their application requesting 3, mgy to serve a population of 36,269 people in In 2004, the City revised their application requesting 3, mgy to serve a population of 41,849 people in The City currently operates three potable water treatment plants (WTP) - the Palmetto Street WTP constructed in 1972, the Fuller s Cross Road WTP constructed in 1992, and the Stoneybrook WTP constructed in The water system did include an additional WTP on Boyd Street, but this plant was decommissioned and water pumped from the Boyd Street well is now piped to the Palmetto Street WTP. The Palmetto Street and Fuller s Cross Road WTPs obtain water from wells (Well No. 1 through 4) completed in the Upper Floridan aquifer. The Stoneybrooke WTP obtains water from a well (Well No. 5) completed in the Lower Floridan aquifer. Well No. 5 was constructed during the application process and water use from this well has been authorized under a Temporary Consumptive Use Permit. The treatment plants provide treatment through aeration and disinfection with chlorine and have a combined permitted capacity of mgd. The finished water is pumped into storage facilities located at each of the treatment plants and then into the distribution system. A-22

The agreement also addresses system interconnections and transfer of customers and distribution service facilities. CITY OF WINTER PARK Facilities The City of Winter Park s service area is substantially developed, and the surrounding areas are in other utilities service areas. Consequently, the projected growth for the service area is primarily due to infill and redevelopment. Potable water for the City of Winter Park s service area is currently provided by four water treatment plants: Swoope, Wymore, Magnolia and University. The four existing water plants combined withdraw groundwater from eight production wells. Currently a fifth plant, the Aloma Plant is under construction and scheduled to come on-line by December 2006 with two recently installed lower Floridan wells, K and L. At that time the University Plant will be shut down and A-23

67 wells H and I at the plant will be abandoned. The University WTP site is being decommissioned due to the fact that it cannot be physically expanded to accommodate planned ozone disinfection facilities. Soon afterward (early 2007) the two Wymore Plant wells, D and E will be converted for use as back-up only. Water supply for this final system will be provided by a total of six wells with two as back-up. All of the current and future active wells will obtain water from the Lower Floridan Aquifer. All active wells are equipped with totalizing flow meters, and all individual service connections are metered. All future wells will be equipped with totalizing flow meters by condition of this permit. The 2003 population of the service area was estimated at 67,940, and the projected 2023 population of the service area estimated at 73,766. The service area is predominately residential and approximately 70 percent of the current potable water use is under the residential use classification (single-family and multifamily). Approximately 22 percent of the water use is by commercial use classification consisting primarily of potable water supply for small businesses, professional offices, churches, and restaurants, 2 percent of the water use is classified as urban landscape use, which includes City parks, schools, City Hall and median irrigation and 6 percent is utility uses and unaccounted for losses. Permits CUP # 7624: Permit issued on October 11, 2005, Average 12.7 million gallons per day (mgd), Maximum annual million gallons for an estimated population of 73,949 in 2025, Permit expires on October 12, Agreements The City of Winter Park has two agreements with Orange County. The Water and Wastewater Territorial Agreement establishes the service territory for the City which includes the incorporated area as well as certain unincorporated areas of Orange County. In addition, Orange County entered into an agreement with the City for Emergency Potable Water Supply Interconnection which includes a letter agreement for the Wymore Road interconnection. The City of Winter Park is in the final stage of a 6 year water system improvement program that includes extensive modifications to the Wymore Road Water Treatment Facility. To accomplish the planned improvements, this facility wili need to be taken out of service during construction. The requested interconnection will provide an emergency source of water in the event that an unforeseen problem with our other water treatment facilities affects the City s ability to provide adequate service to customers on the western fringe of its service area. ZELLWOOD WATER USERS Facilities This small utility provides potable water to the unincorporated town of Zellwood, in northwestern Orange County. The unincorporated community of Zellwood is in northwest A-24

68 Orange County, Florida, on U.S. Highway 441 between the Cities of Apopka and Mount Dora. This community is approximately 3.6 miles north of Lake Apopka. The water supply system consists of Wells 1 (Jones Well) and 2 (King well), raw water mains, water treatment facilities, storage facilities, and pumps and piping for distributing treated potable water. In the past, per capita usage in this service area was higher than normally allocated for similar communities. Through improved water conservation practices, such as repair and placement of leaking water mains, institution of conservation encouraging water rate structure, and performance of individual water audits, as well as better record keeping, the per capita water use has been much lower in recent years. Reclaimed water is not available at this time and is not projected to become available in the Zellwood Water Users service area since all houses and businesses in the area use septic systems for wastewater treatment and disposal. Permits CUP# 3301: Permit issued on March 2, 2004, Average mgd, Maximum annual 88.8 million gallons for an estimated population of 1,826 in 2024, Permit expires on March 2, Agreements This private utility is regulated by the St. Johns River Water Management District, which establishes its territorial boundary. There are no agreements between this utility and Orange County. A-25

69 APPENDIX B Wastewater/Reclaimed Water Facilities Serving Unincorporated Orange County An inventory of available water reclamation and reuse facilities was completed for those public and private utilities providing wastewater treatment and reclaimed water reuse service within unincorporated Orange County. This appendix presents additional information on the existing facilities and related capacities for these wastewater and reclaimed water service providers, which include the following significant utilities: Orange County Utilities Southlake Utilities Orlando (City of) Tohopekaliga Water Authority Apopka (City of) University of Central Florida Mount Dora (City of) Wedgefield Utilities Ocoee (City of) Winter Garden (City of) Orange County Research and Winter Park (City of) Development Authority (Central Florida Research Park) Summaries of the existing water reclamation facility and reuse capacities associated with the above-listed utilities are presented in the data and analysis section of the Orange County Work Plan (see previous Table 3). Orange County Utilities is the largest reclaimed water service provider within unincorporated Orange County. One other large utility, Reedy Creek Energy Services (RCES), provides reclaimed water service within Orange County; however, the RCES reclaimed water service area remains within the jurisdictional boundary of the Reedy Creek Improvement District and does not contribute to the reuse supply within unincorporated Orange County. For this reason, this reuse provider is not addressed as part of Orange County s Work Plan. The suppliers operate numerous water reclamation facilities, which are described in more detail below. This appendix was prepared in May 2008 and reflects status as of this date in time. ORANGE COUNTY UTILITIES (OCU) Treatment Facilities Orange County Utilities (OCU) is the largest wastewater utility and reclaimed water provider in unincorporated Orange County. The Water Reclamation Division of OCU provides wastewater collection and treatment service to over 130,000 connections in unincorporated Orange County and portions of several municipalities through the operation and maintenance of wastewater collection systems, water reclamation facilities, and reuse distribution systems. B-1

70 OCU owns and operates three regional water reclamation facilities (WRFs): the Northwest WRF, the South WRF, and the Eastern WRF. An older sub-regional facility, the Cypress Walk WRF, has been off-line since 2006 and will be demolished by The OCU service area surrounding these facilities includes approximately 1,600 miles of sewer mains, 300 miles of reclaimed water lines, 680 OCU-maintained pump stations, and 2 reclaimed water pump stations. The total annual average wastewater volume treated at OCU facilities in 2005 was 51 mgd. Following treatment, all 51 mgd of the reclaimed water produced in 2005 was used for beneficial reuse. The existing County wastewater/reclaimed water service areas are depicted in Figure B.1. In addition, OCU plans to construct a new Southwest WRF to accommodate future growth in its Southwest Service Area. Figure B.1 Orange County Utilities Wastewater/Reclaimed Water Service Area Reuse Facilities OCU beneficially reuses 100 percent of its reclaimed water from the Eastern, South, and Northwest WRFs. OCU reuses reclaimed water for aquifer recharge through RIBs, public access irrigation, and lake augmentation; for industrial uses such as cooling water; and for wetlands enhancement. These and other reclaimed water reuse systems are permitted as part of the wastewater operational facility permits issued by the Florida Department of Environmental Protection (FDEP). For each water reclamation facility, the County documents the planned end B-2

71 use of the reclaimed water produced. Each issued permit lists both treatment capacity and reclaimed water management system (reuse) capacity, as summarized in Table B.1 below. Using reclaimed water, Orange County provides irrigation to 10 golf courses, over 1,000 singlefamily residences, 3 schools, numerous citrus groves, and several commercial businesses. Additionally, the County recharges approximately 23 mgd into the aquifer through wetlands, RIBs, and augmentation of lakes; and provides approximately 10 mgd of cooling water to the Curtis H. Stanton energy facility. The distribution of Orange County reclaimed water reuse flows in 2005, summarized by type of use, is depicted in Figure B.2 below. Table B.1.

72 Wastewater and Reclaimed Water Agreements OCU maintains the following three primary types of wastewater/reclaimed water agreements: Territorial agreements, defining utility service areas Wholesale service agreements, providing for wholesale or emergency wastewater or reclaimed water service between OCU and other utility providers Regional cooperative agreements, for mutually beneficial reuse initiatives, such as regional interconnection of facilities Orange County s policies and initiatives regarding wastewater and reclaimed water territorial agreements are described in detail in the Intergovernmental Coordination Element. OCU maintains territorial agreements with all the other major wastewater/reclaimed water providers within Orange County, and some of those in neighboring counties, including the following: City of Orlando City of Apopka Econ Utilities (Wedgefield Utilities / Utilities, Inc.) City of Mount Dora City of Ocoee Reedy Creek Improvement District Southlake Utilities Tohopekaliga Water Authority (City of Kissimmee) University of Central Florida City of Winter Garden City of Winter Park As with the potable water supply system, OCU also has a number of service interconnects with other utility wastewater and reclaimed water systems. A number of wholesale wastewater and reclaimed water agreements are in place between the County and other entities (Table B.2). Furthermore, the County is continually seeking opportunities for collaboration and is currently negotiating with multiple utilities regarding potential future reclaimed water service agreements. Table B.2. Orange County Wholesale Wastewater and Reclaimed Water Service Agreements Entity Tohopekaliga Water Authority Reedy Creek Energy Services City of Ocoee Capacity / Conditions OCU has a wholesale agreement that allows for up to 1 mgd, AADF to be treated at Tohopekaliga Water Authority facilities OCU has a wholesale agreement that allows for up to 0.75 mgd, AADF from the Southwest Service Area to be treated at the Reedy Creek Improvement District (RCID) facility OCU (through the Water Conserv II project) has a wholesale agreement to provide reclaimed water from the South Service Area to the City of Ocoee B-4

73 In addition to the territorial and wholesale service agreements discussed above, Orange County currently maintains the following key regional cooperative agreements related to reclaimed water: Water Conserv II Regional Reuse System Agreement, a cooperative agreement between Orange County and the City of Orlando, joint owners of this largest reuse project of its kind (agricultural irrigation) in the world, in place since the mid 1980s Curtis H. Stanton Energy Center Reclaimed Water Service Agreement, for OCU to provide reclaimed water to OUC for cooling at OUC s power generation facility in east Orange County, offsetting the need to use potable water for this purpose Eastern Regional Reclaimed Water Distribution System Agreement (SJRWMD DWSP Project Number 25), an agreement for interconnected reclaimed water reuse distribution facilities at a large regional scale in east Orange County and Seminole County. Led by the City of Orlando, partners to the agreement include Orange County, Seminole County, the City of Oviedo, the University of Central Florida, and OUC. Orange County signed this agreement with the City of Orlando in CITY OF ORLANDO Treatment Facilities The City of Orlando currently operates three water reclamation facilities (Iron Bridge, Water Conserv I, and Water Conserv II WRFs) that treat wastewater to meet public access reclaimed water standards. The water from all three facilities is suitable for residential and commercial landscape irrigation and for other uses to offset groundwater withdrawals. Reuse Facilities The City of Orlando is working in partnership with Orlando Utilities Commission (OUC) to implement a regional reuse program required by OUC s Condition #37 of the CUP issued by SJRWMD. Project RENEW represents a commitment by OUC to provide at least 9.2 mgd of reclaimed water to west Orange County. The primary source of this reclaimed water will be from the City s Iron Bridge Regional Water Reclamation Facility (WRF). In addition, raw wastewater may be diverted from the Iron Bridge WRF service area for treatment at the Water Conserv II facility in western Orange County. Phase I of Project RENEW must provide at least 3 mgd of reclaimed water and must be completed no later than Phase II of the Project RENEW must provide the entire 9l2 mgd of reuse and must be completed by The Eastern Regional Reclaimed Water Distribution System will provide 33 mgd of reclaimed water to golf courses, residential areas and cooling for a power facility. The system is required to be constructed by 2007 which will create facilities to transport reclaimed water from the Iron Bridge Water Reclamation Facility to the southeastern area around Lake Nona. The City estimates that an additional two years are needed to finish construction of this distribution system. OUC has requested to extend this deadline until B-5

74 CITY OF APOPKA Treatment Facilities The Apopka Water Reclamation Facility is the City s primary regional plant, which provides advanced secondary treatment along with high level disinfection to produce reclaimed water that is suitable for use on public access areas like golf courses and home lawns. The Apopka WRF is permitted for a capacity of 4.5 mgd and the City has applied for a permit modification to expand the capacity to 8 mgd. The WRF has two wells that the City uses to supplement the supply of reclaimed water. The WRF has 4 million gallons of covered storage tank capacity and 25 million gallons of storage pond capacity. In addition, the City of Apopka recently purchased one small subregional facility from Orange County, the Plymouth Hills WRF. The Plymouth Hills WRF is a small plant that discharges to one adjacent percolation pond that has a rated capacity of 24,000 gpd, AADF (0.024 MGD). Current average daily flows at this plant are around 0.01 MGD. The City has other storage facilities including the Rock Springs Ridge Golf Course with 20 million gallons of storage pond capacity and is constructing a storage pond with 120 million gallons of capacity at its Northwest Recreation Center. This new storage pond will receive a combination of reclaimed water and storm water runoff. Reuse Facilities The City of Apopka furnishes reclaimed water to users through its Project ARROW (Apopka Regional Reuse Of Water). The Apopka WRF is currently the only source of reclaimed water for the City s system. The City has a reclaimed water pump station at the Apopka WRF and a repump station in the northern part of its service area. The Lake Apopka Reclaimed Water Pump Station is located in the southwestern part of the City s service area. Originally conceived as a pump station, the City is now engaged in a project to assess the feasibility of using Lake Apopka as a supplemental water source for reclaimed water. The City is planning to withdraw up to 5 MGD from the lake. It is envisioned that the surface water treatment plant and the reclaimed water pump station will be constructed on the same site. The pump station could also be the receiving point for reclaimed water that is made available through OUC s Project RENEW. Project RENEW APRICOT is a cooperative project between the Cities of Altamonte Springs and Apopka to enhance their reclaimed water systems. One key aspect of this system consists of a reclaimed line linking the Altamonte Springs APRICOT reclaimed water system and the reclaimed water system of Apopka (ARROW). CITY OF MOUNT DORA Treatment Facilities There are two wastewater treatment plants (WTP), identified as WTP #1 and #2. The newest wastewater treatment plant, plant #2, is also known as the James P. Snell plant, is currently online and is receiving and treating wastewater from approximately 200 homes. The plant has been B-6

75 designed as a 100% reuse facility with a capacity of 1.25 million gallons per day and is intended to treat wastewater flows from the east and southeast portions of the service area, including the planned developments in the Orange County portion of the service area. Reuse Facilities The City currently operates a reclaimed system delivering an estimated 0.89 million gallons per day to 29 locations, that include businesses, schools, orange groves, and a golf course. The City also provides million gallons per day of reuse to individual residents. The City currently sends approximately 0.46 million gallons per day of wastewater to rapid infiltration basins (RIB s) and a sprayfield. The projected capacity for future use of reclaimed water exceeds the projected future wastewater flow and the RIB s and sprayfield are intended to be utilized only as a back up once the additional reuse customers come on-line. A connection schedule for most future reuse sites is difficult because the development schedule is currently too broad however, in the near term the City anticipates that the Villages of Loch Leven, Frank Brown Field and Baucom Nursery should be connected and on reuse in These customers, however, will require an additional 1.15 million gallons per day of reclaimed exceeding the anticipated capacity. In addition, planned reuse connections for common areas within the City will require an additional 0.15 million gallon per day of reuse over the next four years. Long term the City has provided a list of potential customers that will be requiring an additional 2.1 million gallons per day of reuse. At the maximum permit term the City only anticipates wastewater volumes (potential reuse) of approximately 2.75 million gallons per day with an anticipated need of 3.25 million gallons of reclaimed water. Despite the potential deficit of reclaimed capacity, the City requires via ordinance that all new developments install dual distribution systems and the water conservation ordinance requires that reclaimed or non-potable water shall be used for irrigation if available. The City has not requested a back-up source for reclaimed water. The wastewater flow produced by the City is greater than is demanded by its current reuse customers. The City distributes its surplus wastewater to a lined effluent storage facility, rapid infiltration basins and a limited access sprayfield. Currently, the average daily flow to meet reuse demand within the service area is about one half the capacity. CITY OF OCOEE Treatment Facilities The City of Ocoee operates one wastewater treatment plant. The plant is designed to treat 3.0 mgd and has a current effluent capacity of 1.8 mgd. Reuse Facilities In an effort to off-set potable water needs and aquifer withdrawals, the City of Ocoee utilizes reclaimed water for irrigation purposes. Reclaimed water is currently available to the City from three different sources: 1) City of Ocoee s Wastewater Treatment Facility (WWTF); 2) Conserv II and 3) the City of Winter Garden. B-7

76 The City of Ocoee is permitted reuse from their WWTF for irrigation of Forest Lakes Golf Course. The City of Winter Garden also diverts reclaimed water to the Forest Lakes Golf Course. In addition the City has an agreement with Orange County s Conserv II to provide wholesale reclaimed supply for irrigation to all incorporated areas of the City. The agreement sates that after 2007, and average of mgd of reclaimed water will be available to the City. The combined reclaimed water available from all three sources is approximately 3.87 mgd. The City has one development project the Ocoee Reuse System Expansion Project that will provide an additional 0.35 mgd of reuse from the City WWTP. The project was anticipated to be complete in ORANGE COUNTY RESEARCH AND DEVELOPMENT AUTHORITY (CENTRAL FLORIDA RESEARCH PARK) Treatment Facilities Wastewater is discharged off site to the Iron Bridge Regional Wastewater Treatment Facility. Reuse Facilities The City of Orlando will be installing a 42-inch diameter reclaimed water transmission line that will transect the Central Florida Research Park (CFRP) in a north south alignment. The transmission line is part of the City of Orlando regional reclaimed water supply system and is expected to begin installation in the second half of The applicant has proposed to offset future irrigation requirements with reclaimed water from the transmission line if possible, or with on-site surface water. SOUTHLAKE UTILITIES Treatment Facilities Southlake Utilities Waste Water Treatment Facility (WWTF) is an activated sludge treatment facility. Treated effluent is directed to a rapid infiltration basin that consists of two percolation ponds with a total wetted area of acres. Current flows are averaging 0.60 mgd. The Utility recently completed an expansion to the facility to increase the treatment capacity to 1.5 mgd. Reuse Facilities Future modifications will include upgrades to the treatment process in order to meet FDEP Public Access Reuse standards for water quality and construction of reclaimed water distribution system. At present, treated effluent, averaging 0.60 mgd, from Southlake Utilities WWTP is directed to Rapid Infiltration Basins (RIBs) for disposal. The Utility requires all new and proposed subdivisions to install dual-lines as a requirement on Developer s Agreements. At the time of application submittal in 2003, the Utility committed to a timeframe of bringing reuse online by However, the rate of growth in southern Lake County has increased dramatically in the past few years. As such, the Utility will be required, as a condition of permit issuance, to re- B-8

77 examine the feasibility of implementing reuse earlier than Design of the reuse system is anticipated to be complete by January 2007 and the Utility has indicated that the system could be on-line by According to the SJRWMD permit, Southlake Utilities is required to implement the following schedule of reuse system design and construction unless otherwise agreed to by the District: Draft Reuse System Design November 30, 2006 Completion of Reuse System Design January 31, 2007 Begin Construction of Reuse System (WWTP Upgrade and Distribution Lines) January 31, 2008 TOHOPEKALIGA WATER AUTHORITY (TWA) Established in October 2003 by a special act of the Florida legislature, the Tohopekaliga Water Authority (TWA) is the largest provider of water, wastewater and reclaimed water services in Osceola County. TWA currently serves 73,000 water, 71,000 wastewater and 10,000 reclaimed water customers in Kissimmee, Poinciana and unincorporated areas of Osceola County. TWA owns and operates 20 water plants and 10 wastewater plants while maintaining 1,174 miles of water mains, 980 miles of wastewater mains, 242 miles of reclaimed water mains and 357 wastewater pump stations. TWA treats and distributes approximately 35 million gallons of potable water and reclaims 21 million gallons of wastewater each day. TWA wastewater facilities include 10 water reclamation plants, sewage collection facilities and wastewater effluent disposal facilities. TWA Water Reclamation Facilities (WRF) each operate independently for set geographic areas throughout the service area. Wastewater is delivered to the WRF through a network of 980 miles of collection and transmission pipes with 357 wastewater pump stations and 242 miles of reclaimed water distribution mains. The treated reclaimed water produced by the WRF is used for irrigation and the remainder routed to the system rapid infiltration basins to recharge the groundwater. The waste solids (bio-solids) are processed to kill pathogens and then spread over agricultural lands as fertilizers. TWA has committed to development of alternative water supply (AWS) projects, in addition to continued use of reclaimed water, to supplement current and future groundwater withdrawals authorized in this permit. These alternative water supply projects are important because of the identified limitation on future groundwater availability beyond 2013 and the fact at the TWA reclaimed water supplies are not adequate to meet all of their projected water demands. TWA permit has been conditioned to provide one or more alternative water supply project(s) that shall be capable of providing at least 15 million gallons per day to meet the demands within the water utility service areas of the TWA, the City of St. Cloud, Orange County Polk County and Reedy Creek Improvement District not met by the groundwater allocations authorized by the SFWMD through December 31, This commitment will be met by developing alternative supplies from the Cypress Lake Brackish Groundwater Wellfield and/or the Kissimmee River Chain of Lakes Project and/or other AWS projects. B-9

78 Additional conditions of TWA permit require further development of AWS beyond what is necessary to meet its immediate needs beyond Under these conditions, one or more additional AWS projects must be identified by December 31, 2011 that when combined with the projects above in time to meet all of TWA public supply water demands through 2027 that are not met by allocations of groundwater authorized by the SFWMD and by the 15 million gallons per day of AWS from the Cypress Lake Brackish Groundwater Wellfield and/or Kissimmee River Basin projects required to be developed for use by The conditions require timely submittal of detailed information and a schedule for required actions to assure the alternative water supply is developed. UNIVERSITY OF CENTRAL FLORIDA (UCF) Treatment Facilities The UCF does not operate any wastewater facilities. Transfer of wastewater treatment services from the University Treatment Plant to the Iron Bridge Wastewater Treatment Facility was completed in June At that time, UCF decommissioned their wastewater treatment facility. Reuse Facilities UCF has an agreement with the Iron Bridge Wastewater Treatment Facility to receive reclaimed water for irrigation. Reclaimed water from the Iron Bridge Wastewater Treatment Facility was scheduled to be online and supply all irrigation demand in the University by March WEDGEFIELD UTILITIES Wedgefield Utilities owns and operates a wastewater treatment plant that is currently generating a daily average million gallons per day of reclaimed water. Approximately million gallons per day average, or 73.4% of the reclaimed water is currently irrigating approximately 120 acres of golf course turf. The remainder of the wastewater, million gallons per day average, or 26.6% is used to recharge the aquifer via an onsite spray field. As a condition of SJRWMD permit, the utility is required to submit a yearly reuse report, which describes the activities that have occurred during the previous year to further implement the reuse of reclaimed water as the wastewater flow increases. CITY OF WINTER GARDEN Treatment Facilities The City of Winter Garden owns and operates one wastewater treatment facility Crest Avenue WWTP, which has a current permitted capacity of 2.0 mgd. The plant is undergoing an expansion to increase the plant capacity to 4.0 mgd, but the permitted capacity is limited to 2.0 mgd because the permitted disposal capacity is only 2.0 mgd. The WWTP has existing tertiary filters and the ability to provide high-level disinfection. The effluent consistently meets or exceeds Public Access reuse water quality. In 2004, the average daily flow from the WWTP was 1.90 mgd. The facility employs a method of effluent disposal which discharges treated wastewater to eight (8) percolation ponds equipped with an underdrain system. The effluent B-10

79 collected in the underdrain flows by gravity through approximately one mile of wetlands before final discharge into Lake Apopka. Reuse Facilities At the time of permit renewal, in July 1996, the City did not provide reclaimed water for irrigation purposes either within or outside of its service area. The WWTP was an advancedsecondary, activated sludge facility with ultimate discharge to Lake Apopka. With funding from the District, the City completed a Reuse Feasibility Study in July One of the alternatives proposed in this study was a joint-venture, reclaimed water system with the City of Ocoee, which Winter Garden decided to pursue. An inter-local agreement was finalized between these two cities on May 4, In this agreement, the City of Ocoee agreed to accept up to 0.75 mgd of reclaimed water from the City of Winter Garden for use at the Forest Lake Golf Course concurrent with the City of Winter Garden accepting up to 0.25 mgd of wet weather discharge from the City of Ocoee. However, the Florida Department of Environmental Protection (FDEP) Operating Permits for both Winter Garden and Ocoee currently limits this transfer of reclaimed water from Winter Garden to the Forest Lakes Golf Course to only 0.25 mgd. To date, the rate of expansion of Ocoee s reclaimed water system has not been sufficient to meet increased effluent flows from Winter Garden, so the City has considered additional reuse alternatives, which include the following: Inter-local Agreement with City of Apopka, April 2002, for the development of a regional reuse facility to allow distribution, via a reclaimed water transmission main between Winter Garden and Apopka, of reuse through systems in both cities. Design phase is complete. Implementation has not been determined. Negotiations regarding reuse distribution and supply options with Louis Dreyfus Citrus, Inc., Orange County and Orlando Utilities Commission. Direct reuse of the City of Orlando s effluent flows to residential and commercial properties within the City s service area boundary. The City of Winter Garden is currently working with Orange County, the Orlando Utilities Commission and the City of Orlando to use reclaimed water in new developments that are being constructed in the southern part of their service area. As mentioned earlier, this is the area where most of Winter Garden s growth potential exists and the newly implemented Reuse Ordinance requires all new developments to install reuse lines. The City is working on a draft Agreement for the delivery and use of reclaimed water from the City of Orlando and Orange County. In addition, the City has committed to a Capital Improvement Program involving the construction of the infrastructure necessary to serve the northeast area of Winter Garden from the Crest WWTP over the next five years. B-11

80 CITY OF WINTER PARK Treatment Facilities The wastewater flow produced by the City is substantially more than is demanded by its reuse customers. The City distributes its surplus wastewater to other reclaimed systems via agreements with Iron Bridge, Water Conserv II, and the City of Altamonte Springs. As a result of these agreements the City uses only a small portion of its wastewater effluent via the operation of the Winter Park Estates Wastewater Treatment Facility (WWTF), which has a permitted capacity of 0.75 mgd. Currently, the average daily flow to meet reuse demand within the service area is about one half the capacity. In addition, the City currently has an 8% (0.027 mgd) buffer between average daily total demand and available the reclaimed product. Reuse Facilities All of the City s wastewater is currently being sent to one of four reclaimed systems: Iron Bridge, APRICOT (Altamonte Springs), Water Conserv II or the City of Winter Park System. The City of Winter Park participates with The City of Orlando in the Iron Bridge Water Reclamation Facility (WRF) and the Water Conserv II WRF to treat the majority of its wastewater. Winter Park reserves mgd and 1.0 mgd respectively for the Iron Bridge and Conserv II WRF s. It also has an agreement with the City of Altamonte Springs to supply up to mgd of raw wastewater to be utilized in the Altamonte APRICOT reclaimed system. As a result of these agreements the City controls only a small portion of its wastewater effluent via the operation of the Winter Park Estates Wastewater Treatment Facility (WWTF), which has a permitted capacity of 0.75 mgd average daily flow. Currently, of the average daily flow of million gallons, million gallons or approximately 92% is used daily by the following reuse customers: Winter Park Golf Course Glen Haven Memorial Park Showalter Field/Cady Way Park Interlachen Country Club On-site irrigation at the treatment facility B-12

81 APPENDIX C Demand Projections for Major Potable Water Suppliers Serving Unincorporated Orange County In support of this Work Plan, this appendix presents additional detailed information regarding the demand projections developed by the two largest potable water supply utilities serving unincorporated Orange County: Orange County Utilities (OCU) and the Orlando Utilities Commission (OUC). The following pages present a series of tables containing demand projections for these two suppliers. Detailed background data on the development of demand projections for other water suppliers were not readily available; however, the other suppliers represent only a small percentage of supply in unincorporated Orange County. Information is presented on both the total projected water demand within each utility s entire service area, and that portion of the supplier s service area within unincorporated Orange County. For consistency, all demand projection data are reported as total water demand, which includes all potable and non-potable needs within the utility service areas. These total demands can be satisfied by a combination of water supply sources, including groundwater, reclaimed water, surface water, etc., along with management techniques such as water conservation. In addition, total water demand can vary significantly with time, such as variations observed on an hourly, daily, monthly, or annual basis. Again, to maintain consistency, all baseline water demand projections used to develop this Work Plan were compiled on an annual average basis, assuming long-term average climatic conditions. For consumptive use permitting, the water management districts normally allow a utility to plan for and receive an allocation for demands anticipated to occur under a 1-in-10-year drought rainfall condition. As a rule of thumb, the water management districts typically assume 1-in-10 drought demands will be approximately 6 percent greater than demands during an average rainfall year. The total water demand projections for the OCU potable water service area were developed using population projections originally developed by the SJRWMD, which were validated against future projections from the MetroPlan Orlando (MPO) population database distributed within Traffic Analysis Zone (TAZ) and Orange County Property Appraiser parcel boundaries. These population projections were multiplied by average historic OCU gross per capita water demand unit rates to estimate future water demand within the OCU service areas. As footnoted in attached Table C.1, the OCU demand projections presented are consistent with the information presented to the SJRWMD in negotiation of the recent CUP #3317 (for the OCU East and West Service Areas) and to the SFWMD as part of the recent issuance of WUP # W (for the OCU South and Southwest Service Areas). In addition, the OCU demand projections presented are similar to the current draft demand projections estimated for the OCU service area by GIS Associates, Inc. (contractor to SJRWMD) in development of the upcoming 2008 Water Supply Assessment. C-1
