11 East Niles Community Services District Urban Water Management Plan SECTION 1 INTRODUCTION AND OVERVIEW 1.1 Background and Purpose This report comprises the 2015 Urban Water Management Plan (UWMP or Plan) update for the East Niles Community Services District (ENCSD or District). ENCSD is located on the northeast side of Bakersfield California, located in Kern County. The District serves portions of the Bakersfield community and unincorporated areas of Kern County. ENCSD is an independent Special District formed and operated pursuant to Government Code et seq. ENCSD provides water, wastewater, and drainage services to its customers pursuant to Government Code 61100(a) and (b). ENCSD does not have land planning authority, which is retained by the County of Kern. The purpose of the UWMP is to provide a valuable planning document that may be used for multiple purposes including the following: Meet a statutory requirement of the California Water Code Provide a key source of information for Water Supply Assessments (WSAs) and Written Verifications of Water Supply required by SB 610 and SB 221 Support regional long-range planning documents including City and County General Plans Provide a standardized methodology for water utilities to assess their water resource needs and availability Evaluate compliance with the 2015 daily per-capita water use identified in the 2010 UWMP in accordance with the Water Conservation Act of Urban Water Management Planning and the California Water Code The California Urban Water Planning Act (Act) requires urban water suppliers that have 3,000 or more service connections or supply 3,000 or more acre-feet per year (AFY) of water to develop an UWMP which is submitted to the California Department of Water Resources (DWR) every five years in years ending in 5 and 0. The Plan is required to describe and evaluate water deliveries and uses, sources of supply, reasonable and practical efficient water uses, demand management activities, and water shortage contingency planning. ENCSD prepared its 2015 UWMP based on the guidance presented in the Final DWR 2015 Urban Water Management Plans Guidebook for Urban Water Suppliers (Guidebook) dated March The format of the Plan follows the suggested organization in Part 1, Section 1 of the Guidebook and incorporates all suggested tables, including DWR s standard numbering, to facilitate review of the Plan by DWR. Some of the standardized tables are not applicable to the District s Plan and are noted as such. Furthermore, subsections presented in the guidebook that are not applicable to the District s plan have also been omitted Applicable Changes to the Water Code since 2010 UWMP s Table 1-1 provides an overview of changes to the Water Code since the 2010 UWMPS: Page 1-1

13 East Niles Community Services District Urban Water Management Plan SECTION 2 PLAN PREPARATION 2.1 Basis for Preparing a Plan Law CWC Urban water supplier means a supplier, either publicly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. An urban water supplier includes a supplier or contractor for water, regardless of the basis of right, which distributes or sells for ultimate resale to customers. This part applies only to water supplied from public water systems CWC (b) Every person that becomes an urban water supplier shall adopt an urban water management plan within one year after it has become an urban water supplier. CWC (a) Each urban water supplier shall update its plan at least once every five years on or before December 31, in years ending in five and zero, except as provided in subdivision (d). (d) Each urban water supplier shall update and submit its 2015 plan to the department by July 1, CWC (a)(2) The plan, or amendments to the plan, submitted to the department shall include any standardized forms, tables, or displays specified by the department. CWC (a) The department, in consultation with the board, the California Bay-Delta Authority or its successor agency, the State Department of Public Health, and the Public Utilities Commission, shall develop a single standardized water use reporting form to meet the water use information needs of each agency, including the needs of urban water suppliers that elect to determine and report progress toward achieving targets on a regional basis as provided in subdivision (a) of Section (b) At a minimum, the form shall be developed to accommodate information sufficient to assess an urban water supplier s compliance with conservation targets pursuant to Section The form shall accommodate reporting by urban water suppliers on an individual or regional basis as provided in subdivision (a) of Section California Health and Safety Code (h) Public Water System means a system for the provision of water for human consumption through pipes or other constructed conveyances that has 15 or more service connections or regularly serves at least 25 individuals daily at least 60 days out of the year. ENCSD is a public urban water supplier that both serves more than 3,000 customers and provides more than 3,000 AFY of potable water to its customers.

14 East Niles Community Services District Urban Water Management Plan 2.2 Regional Planning ENCSD has prepared an individual UWMP update for 2015 as identified in Table Individual or Regional Planning and Compliance ENCSD has developed an UWMP that reports solely on its service area. The individual UWMP addresses all requirements of the California Water Code (CWC). ENCSD has notified and coordinated with appropriate regional agencies and constituents during the development of this UWMP update. The agencies contacted are identified in Table 2-5. Table 2-2: Plan Identification Individual UWMP Regional UWMP (RUWMP) Select One: RUWMP includes a Regional Alliance RUWMP does not include a Regional Alliance 2.4 Fiscal or Calendar Year and Units of Measure Law CWC (a)(1) Urban retail water suppliers may determine the targets on a fiscal year or calendar year basis. ENCSD is an urban water retailer. The tables present in the UWMP contain information based on calendar years as presented in Table 2-3. Table 2-3: Agency Identification Type of Agency Agency is a wholesaler Agency is a retailer Fiscal or Calendar Year UWMP Tables Are in Calendar Years UWMP Tables Are in Fiscal Years Units of Measure Used in UWMP Unit AF 2.5 Coordination and Outreach Law CWC (j) An urban water supplier that relies upon a wholesale agency for a source of water shall provide the wholesale agency with water use projections from that agency for that source of water in five-year increments to 20 years or as far as data is available. The wholesale agency shall provide information to the urban water supplier for inclusion in the urban water supplier s plan that identifies and quantifies, to the extent practicable, the existing and planned sources of water as required by subdivision (b), available from the wholesale agency to the urban water supplier over the same five-year increments, and during various wateryear types in accordance with subdivision (c). An urban water supplier may rely upon water supply information provided by the wholesale agency in fulfilling the plan informational requirements of subdivisions (b) and (c). Page 2-2

15 East Niles Community Services District Urban Water Management Plan Wholesale and Retail Coordination The ENCSD has provided to the Kern County Water Agency (KCWA) projections on water use for their wholesale supply in five-year increments for the next 20 years. The wholesale agreement between KCWA and ENCSD is further discussed in Section 6. Table 2-4 Retail: Water Supplier Information Exchange The retail supplier has informed the following wholesale supplier(s) of projected water use in accordance with CWC Wholesale Water Supplier Name Kern County Water Agency Coordination with Other Agencies and Community Law CWC (d)(2) Each urban water supplier shall coordinate the preparation of its plan with other appropriate agencies in the area, including other water suppliers that share a common source, water management agencies, and relevant public agencies, to the extent practicable. CWC Each urban water supplier shall encourage the active involvement of diverse social, cultural, and economic elements of the population within the service area prior to and during the preparation of the plan. ENCSD coordinated with multiple neighboring agencies during the preparation of this UWMP update. A summary of the coordination activities conducted by the District is presented in Table 2-5.

The District notified both the City of Bakersfield (City or COB) and the County of Kern (County) that the plan was being updated and reviewed for possible amendments and changes. This notification was completed 60 days prior to the UWMP public hearing conducted on April 21, A summary of these notifications can be viewed in Section 10 of the UWMP. Page 2-4

17 East Niles Community Services District Urban Water Management Plan SECTION 3 SYSTEM DESCRIPTION 3.1 General Description Law CWC Section Describe the service area of the supplier. ENCSD was formed by an election held December 21, 1954, in accordance with Community Services District Law of the State of California. On November 8, 1955, the voters approved a resolution providing for the issuance of $1,500,000 of revenue bonds. The proceeds of these bonds were used to acquire the properties and rights of the East Bakersfield Water Company and the Pacific Water Company. During the month of April 1956, the District commenced operations for the purpose of furnishing water distribution services to the residents within its boundaries. In 1960, the voters of the District petitioned to have the powers of the District expanded to include sanitary sewer. Some years later, the voters approved a combination general obligation and revenue bond issue to fund the construction of the sewer collection system. The District entered into a joint exercise of powers agreement with the City of Bakersfield for sewage treatment and agreements with both the City of Bakersfield and County of Kern for joint use of sewer trunk lines. The District is controlled by an elected Board of Directors (Board) which consists of a President, Vice President and three Directors. The General Manager is responsible for the day to day operations of the District. Figure 3-1 shows the location of the District within Kern County. According to a 1959 report, the District when originally formed covered 2,440 acres, served approximately 3,100 water connections, and provided service to a population of approximately 10,500 people. There have been a total of 42 annexations during the history of the District and the District now covers approximately 6,202 acres, serves approximately 7,822 connections, and provides services to a population of approximately 35,364 people. At present, there are multiple areas within the District s service area boundary that are not served by the District. Figure 3-2 displays the Districts boundary and the areas inside the boundary that are not served by the District. Areas within ENCSD that overlap with the City of Bakersfield are also shown on Figure 3-2. ENCSD s Sphere of Influence identifies areas outside the existing service area boundary for which ENCSD can provide services. The Sphere of Influence includes approximately 14,570 acres. Most of the District s Sphere of Influence is also included in the City of Bakersfield s Sphere Influence. Approximately 85% of the land inside the District s service boundary has been developed into urban areas. Of the approximately 8,400 acres that exist inside the District s sphere of influence and outside the Districts current service area, approximately 90% is undeveloped or agricultural land. The District s water system is divided into five pressure zones that generally drop from the highest elevations in the north the lower elevations in the south. Surface water generally enters the system from the north and the District s groundwater resources are generally located in the southern portion of the service area. ENCSD is located in eastern Bakersfield, California. Bakersfield is situated near the southern horseshoe end of the San Joaquin Valley, with the Sierra Nevada Mountains to the east, the Tehachapi Mountains to the south, and the Temblor Range to the west. Elevations in the District range from almost 900 feet to less than 400 feet above sea level. The highest elevations are on the north, with somewhat lower elevations on the east, and the lowest elevations to the south and southwest. In general, the land slopes downhill to the southwest.

22 East Niles Community Services District Urban Water Management Plan 3.2 Service Area Climate Law CWC Section Describe the service area of the supplier, including climate. The local climate is characterized by hot, dry summers and cooler, more humid winters. The Bakersfield area enjoys clear sunny days for more than half of the year. Minimum temperatures often drop below 40 degrees Fahrenheit during the winter. Summers are hot with over 100 days per year exceeding 90 degrees Fahrenheit. Annual precipitation in the area averages approximately 6.5 inches and rain ( 0.01 inches per day) occurs about 40 days per year. Fog is common in the winter and may last for several weeks at a time. The 2015 average reference evapotranspiration, temperature, and precipitation are presented in Table 3-0. Table 3-0: Climate Conditions for Calendar Year 2015 Month Standard Monthly Average ETo* Monthly Precipitation** Average Monthly Temperature** Inches Inches Fahrenheit Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Annual *Data from CIMIS Station #005 Shafter, January 1, 2015 to December 31, 2015 ** Data from NOAA Station Bakersfield 5, January to December 31, Service Area Population and Demographics Law CWC Section Describe the service area of the supplier, including current and projected population The projected population estimates shall be based upon data from the state, regional, or local service agency population projections within the service area of the urban water supplier and shall be in five-year increments to 20 years or as far as data is available. The DWR population tool was used to determine the population size inside the District s service since the District boundary does not substantially overlie a city boundary or a census designated place (CDP). In order to use the DWR population tool, service area maps for the census years 1990, 2000, and 2010 were developed and uploaded into the online tool. Page 3-6

23 East Niles Community Services District Urban Water Management Plan Table 3-1 summarizes the current and projected population within ENCSD s service area over the next 25 years. By the year 2040 the population within ENCSD is expected to reach approximately 55,204. Output from the DWR Population tool for the historical and current District populations is included in Appendix B. Table 3-1 Retail: Population - Current and Projected Population (opt) Served 35,364 39,133 43,043 47,008 51,077 55,204 Population projections for the Districts service area from 2015 through 2040 were based on 2015 DWR-projected population and then adjusted using information obtained from the California Department of Finance (DOF). The current 2015 population estimate was provided by the DWR population tool. The 5-year increment projections through 2040 were then calculated using the DOF Total Population Projections for California Counties: July 1, 2015 to 2060 in 5-year Increments spreadsheet projections for the County of Kern. Table 3-2 presents the 5-year growth rates used to project future populations inside the District s service area. Given that District s service area has not been fully built out and that large undeveloped areas exist within the District s sphere of Influence, it is reasonable to assume that growth can be accommodated in the District. County projected growth rates are higher than the historical growth rates within the District. Table 3-2: Population Growth Rate for ENCSD Year Annual Growth Rate, for each 5-year increment % % % % % Note: Growth rates based on DOF projections which are based on 2010 Census Other Demographic Factors Law CWC Describe the service area of the supplier, including... other demographic factors affecting the supplier s water management planning. The District s service area is largely residential as previously noted with areas of commercial, industrial, and agricultural uses intermixed. There are significant differences in residential lot types such as the larger lots in the Bakersfield County Club location and the agricultural areas in the southern part of the service area and smaller lots in the central part of the District service area. Although there may be changes in the individuals residing at any given address through the year (potentially tied to agricultural seasonal work) the number of connections and usage per connection appears to remain consistent.

24 East Niles Community Services District Urban Water Management Plan SECTION 4 SYSTEM WATER USE 4.1 Recycled versus Potable and Raw Water Demand At present, no recycled water is used within the District to offset potable and raw water demands. ENCSD contracts with the City to treat the District s wastewater at the City s Wastewater treatment plant No. 2 where it is understood that the wastewater is treated to a secondary level and used to irrigate crops for restricted uses. The recycled water program and opportunities are discussed in further detail in Section 6.5 of the UWMP. 4.2 Water Uses by Sector Law CWC (e)(1) Quantify, to the extent records are available, past and current water use, over the same five-year increments described in subdivision (a), and projected water use, identifying the uses among water use sectors, including, but not necessarily limited to, all of the following uses: (A) Single-family residential. (B) Multifamily. (C) Commercial. (D) Industrial. (E) Institutional and governmental. (F) Landscape. (G) Sales to other agencies. (H) Saline water intrusion barriers, groundwater recharge, or conjunctive use, or any combination thereof. (I) Agricultural (2) The water use projections shall be in the same five-year increments described in subdivision (a). ENCSD is fully metered for all customers, including separate meters for single-family residential, commercial, large landscapes, and all institutional/governmental facilities. A summary of the 2015 metered water use by use type is presented in Table 4-1.

For all subsequent updates, the distribution system water loss shall be quantified for each of the five years preceding the plan update. (B) The distribution system water loss quantification shall be reported in accordance with a worksheet approved or developed by the department through a public process. The water loss quantification worksheet shall be based on the water system balance methodology developed by the American Water Works Association. Distribution system water losses (also known as real losses ) are the physical water losses from the water distribution system and the supplier s storage facilities, up to the point of customer consumption. The American Water Works Association (AWWA) developed a method for quantifying distribution system losses. This AWWA method was used to quantify losses within the District s system. A copy of the AWWA Water Audit Tool is available for reference in Appendix D and was submitted electronically to the DWR using the DWR online submittal tool. Table 4-4 presents the 2015 volume of water loss as calculated using the AWWA method. Page 4-2

(B) To the extent that an urban water supplier reports the information described in subparagraph (A), an urban water supplier shall do both of the following: (i) Provide citations of the various codes, standards, ordinances, or transportation and land use plans utilized in making the projections. (ii) Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or transportation and land use plans. Water use projections that do not account for these water savings shall be noted of that fact. Future water savings are not included in the future demand projections previously presented. Lower income residential demands are included in the projections. Table 4-5 Retail Only: Inclusion in Water Use Projections Are Future Water Savings Included in Projections? If "Yes" to above, state the section or page number, in the cell to the right, where citations of the codes, ordinances, etc utilized in demand projections are found. Are Lower Income Residential Demands Included In Projections? No - Yes 4.5 Water Use for Lower Income Households Law CWC (a) The water use projections required by Section shall include projected water use for single-family and multifamily residential housing needed for lower income households, as defined in Section of the Health and Safety Code, as identified in the housing element of any city, county, or city and county in the service area of the supplier. California Health and Safety Code (a) Lower income households means persons and families whose income does not exceed the qualifying limits for lower income families In the event the federal standards are discontinued, the department shall, by regulation, establish income limits for lower income households for all geographic areas of the state at 80 percent of area median income, adjusted for family size and revised annually. The projections for the residential category of user have been developed to account for the use by single-family and multi-family low-income residential housing needs. ENCSD consulted the Kern County Council of Governments (Kern COG) Regional Housing Needs Assessment to determine the percentage of low-income housing within the Bakersfield (and thus the ENCSD) area. Based on the projected needs contained therein, it was determined that approximately 42.7% of the future housing need would be very low and low income. The ratio of single-family to multi-family housing in the future was projected to be equivalent to the current ratio of 4.87 within ENCSD. Table 4-6a contains projections of demand for single-family and multi-family low-income housing through Low-income housing water demand projections were included in the water demand projections presented in Table 4-2.

28 East Niles Community Services District Urban Water Management Plan SECTION 5 SB X7-7 BASELINES AND TARGETS 5.1 Updating Calculations from 2010 UWMP Law CWC (g) An urban retail water supplier may update its 2020 urban water use target in its 2015 urban water management plan required pursuant to Part 2.6 (commencing with Section 10610). Methodologies DWR 2011, Methodology 2 Service Area Population Page 27 - Water suppliers may revise population estimates for baseline years between 2000 and 2010 when 2010 census information becomes available. DWR will examine discrepancy between the actual population estimate and DOF s projections for 2010; if significant discrepancies are discovered, DWR may require some or all suppliers to update their baseline population estimates Update Target Method The District used Target Method 1 to update their 2020 water use target. This method is described in further detail in Section Required use of 2010 U.S. Census Data DWR determined that discrepancies exist between the DOF s projected populations for 2010 (based on the 2000 census) and actual 2010 populations. The average difference in populations was approximately 3%, but in some areas as high as 9%. Based on this discrepancy, ENCSD has elected to recalculate their service area population for the 2015 UWMP update using the DWR population tool. This population update has changed the baseline and target Gallons per Capita per Day (GPCD) values that as compared to the 2010 UWMP SB X7-7 Verification Form The District has completed the SB X7-7 verification form in order to demonstrate compliance with the Water Conservation Plan Act. These tables are available for reference in Appendix C. The tables have also been submitted online using the DWR online submittal tool. 5.2 Baseline Periods Law CWC (e) An urban retail water supplier shall include in its urban water management plan due in the baseline daily per capita water use along with the bases for determining those estimates, including references to supporting data. (g) An urban retail water supplier may update its 2020 urban water use target in its 2015 urban water management plan required pursuant to Part 2.6 (commencing with Section 10610) Determination of the Year Baseline Period (Baseline GPCD) Law CWC (b) Base daily per capita water use means any of the following: (1) The urban retail water supplier s estimate of its average gross water use, reported in gallons per capita per day and calculated over a continuous 10-year period ending no earlier than December 31, 2004, and no later than December 31, Page 5-1

29 East Niles Community Services District Urban Water Management Plan (2) For an urban retail water supplier that meets at least 10 percent of its 2008 measured retail water demand through recycled water that is delivered within the service area of an urban retail water supplier or its urban wholesale water supplier, the urban retail water supplier may extend the calculation described in paragraph (1) up to an additional five years to a maximum of a continuous 15-year period ending no earlier than December 31, 2004, and no later than December 31, Recycled water comprised less than 10% of the District s water deliveries during 2008 and therefore a 10 year baseline period was used to calculate the District s baseline target GPCD. The 10 year baseline period, the same as used in the 2010 UWMP, begins on January 1 st, 1995 and continues through December 31 st, Determination of the 5-year Baseline Period (Target Confirmation) Law CWC (b) (3) For the purposes of Section , the urban retail water supplier s estimate of its average gross water use, reported in gallons per capita per day and calculated over a continuous five-year period ending no earlier than December 31, 2007, and no later than December 31, In addition to the 10-year baseline GPCD period, the water use, in GPCD, was calculated over a 5-year baseline confirmation period. The 5-year baseline confirmation period, the same as used in the 2010 UWMP, begins on January 1 st, 2003 and continues through December 31 st, Service Area Population Law CWC (e) An urban retail water supplier shall include in its urban water management plan due in 2010 the baseline per capita water use, along with the bases for determining those estimates, including references to supporting data. (f) When calculating per capita values for the purposes of this chapter, an urban retail water supplier shall determine population using federal, state, and local population reports and projections. CWC (a)(2) The plan shall include any standardized forms, tables or displays specified by the department DWR Population Tool As stated Section 3.4, the District utilized the DWR population tool to calculate the 2015 population within the District s service area. Electronic maps of ENCSD s service boundaries for 1990, 2000 and 2010 (census Years) were uploaded into the population tool along with number of single-family residence and multi-family residence connections for each of the baseline confirmation years. The PWR Population tool calculated the District s population for the 10-year baseline period and 5-year baseline confirmation period.. The tool projected higher 2010 and 2015 populations than those presented in the 2010 UWMP estimates. 5.4 Gross Water Use Law CWC (g) Gross Water Use means the total volume of water, whether treated or untreated, entering the distribution system of an urban retail water supplier, excluding all of the following: (1) Recycled water that is delivered within the service area of an urban retail water supplier or its urban wholesale water supplier Page 5-2

30 East Niles Community Services District Urban Water Management Plan (2) The net volume of water that the urban retail water supplier places into long term storage (3) The volume of water the urban retail water supplier conveys for use by another urban water supplier (4) The volume of water delivered for agricultural use, except as otherwise provided in subdivision (f) of Section California Code of Regulations Title 23 Division 2 Chapter 5.1 Article Section 596 (a) An urban retail water supplier that has a substantial percentage of industrial water use in its service area is eligible to exclude the process water use of existing industrial water customers from the calculation of its gross water use to avoid a disproportionate burden on another customer sector. Gross water use or the measure of water that enters the distribution system over a 12-month period has been reported for each year in the baseline periods and for 2015, the compliance year. The gross water use data was taken from the Yearly Public Water System Statistic reports submitted to the DWR. 5.5 Baseline Daily Per Capita Water Use (GPCD) The 10-year and 5-year baseline daily per capita water use (GPCD) was generated using the standardized SBX7-7 verification tables. The Baseline GPCD values are calculated by dividing service area population by the annual gross water use. The SB X7-7 verification tables are available for reference in Appendix C. The baseline average GPCD for the 10-year baseline and 5-year baseline confirmation years are presented in Table and 2020 Targets Select and Apply a Target Method ENCSD selected Target Method #1 from CWC (b) to determine its target water use for This method constitutes a 20% reduction in the District s baseline GPCD water use. The 2015 (interim) water use reduction is 5% of the baseline GPCD Year Baseline 2020 Target Confirmation Law CWC Notwithstanding the method adopted by an urban retail water supplier pursuant to Section , an urban retail water supplier s per capita daily water use reduction shall be no less than 5 percent of base daily per capita water use as defined in paragraph (3) of subdivision (b) of Section This section does not apply to an urban retail water supplier with a base daily per capita water use at or below 100 gallons per capita per day. The District s 2020 target water use reduction is greater than 5% of the 5-year baseline. Table 5-1 shows that the 5- year base line water use is 333 GPCD. The 2020 confirmed target is 311 GPCD which is a 6.6% reduction from the 5-year baseline water use Calculate the 2015 Interim Urban Water Use Target The 2015 interim target water use is defined as the halfway point between the 10-year baseline GPCD (from SB X7-7 Table 5) and the confirmed 2020 target water use (from SB X7-7 Table 7). The halfway point between the 10-year baseline water use of 389 GPCD and the 2020 confirmed water use target give a 2015 interim target water use of 311 GPCD Baselines and Target Summary 10-year baseline, 5-year baseline, 2015 interim target, and 2020 confirmed target water uses are summarized in Table 5-1.

CWC (d)(1) When determining compliance daily per capita water use, an urban retail water supplier may consider the following factors: (A) Differences in evapotranspiration and rainfall in the baseline period compared to the compliance reporting period. (B) Substantial changes to commercial or industrial water use resulting from increased business output and economic development that have occurred during the reporting period. (C) Substantial changes to institutional water use resulting from fire suppression services or other extraordinary events, or from new or expanded operations, that have occurred during the reporting period. (2) If the urban retail water supplier elects to adjust its estimate of compliance daily per capita water use due to one or more of the factors described in paragraph (1), it shall provide the basis for, and data supporting, the adjustment in the report required by Section Methodologies for Calculating Baseline and Compliance Urban Per Capita Water Use, Methodology 4 This section discusses adjustments to compliance-year GPCD because of changes in distribution area caused by mergers, annexation, and other scenarios that occur between the baseline and compliance years.

32 East Niles Community Services District Urban Water Management Plan SECTION 6 SYSTEM SUPPLIES 6.1 Purchased or Imported Water With the development of the water treatment facilities in connection with the KCWA Improvement District No. 4 (ID4), ENCSD was able to execute a contract for 5,000 acre feet of treated surface water annually. The Henry C Garnett Water Purification Plant (HCGWPP) is rated to treat 45 million gallons per day (MGD). The HCGWPP completed a treatment facilities expansion that increased the peaking capacity of the plant and associated distribution facilities. As part of the planning process for the expansion project, ENCSD and the KCWA signed a water supply contract that provides ENCSD with an additional 6,000 AF of water per year on top of the existing 5,000 AF (or 11,000 AF in total). Per the September 2005 Agreement Between Kern County Water Agency and East Niles Community Services District for a Water Supply (see copy in Appendix E), the water supply is to be for the benefit of the lands and inhabitants served by ENCSD within the confines of KCWA s ID4. If and when the District acquires a water supply that could be treated at the HCGWPP, then water (with agreement from KCWA) could be moved to serve other areas within the District which may be outside of KCWA s ID4. Tables 6-8 and 6-9 summarize the current and projected Kern County Water Agency surface water supply. 6.2 Groundwater At the time the District was formed, groundwater was the single water supply source available to the District service area. Over the years, surface water sources have become available to the District and currently represent approximately half of the total water supply. The District operates their system to prioritize the use of the surface supply (within ID4) and supplements with the groundwater supply. It is expected that the District will continue to use the combination of surface and groundwater supply sources to meet existing and future customer demands within the District s service area. ENCSD presently has seven active groundwater wells spaced throughout the lower elevation, southern portion, of the District. The pumping capacities for the seven wells are as follows (the annual capacities listed assume wells operate 75% of day): Well gpm (665 AFY) Well gpm (1,028 AFY) Well gpm (1,028 AFY) Well 19 2,000 gpm (2,420 AFY) Well 20 1,600 gpm (1,936 AFY) Well 21 1,400 gpm (1,694 AFY) Well gpm (544 AFY) All of the wells, with the exception of Well 21, are configured such that they do not pump directly into the distribution system, but rather all pump to a common distribution location, which is called the Kern Citrus Tank Facility. The District relies on the booster pump station at the Kern Citrus Tank Facility to pump the well water into the higher elevation storage reservoirs in the northern portion of the District. Although the combined capacity of all wells is slightly more than 9,300 AF per year (assuming wells run 18 hours per day), the amount of water that is available to the District, except that area served by Well 21, is limited by the capacity of the Kern Citrus booster pump facility, which is currently approximately 5,300 gpm (8,550 AF/YR). In order to realize the full benefit of the District s existing and planned wells the booster pump facility will need to be upgraded to exceed the well capacity (approximately 7,700 gpm). It should be noted that the design of the Kern Citrus Pump Station is such that the capacity can be expanded to 7,840 gpm if a fourth pump is installed and the main transmission line to the ENCSD Pump Station is replaced. Page 6-1

33 East Niles Community Services District Urban Water Management Plan In order to project pumped water volumes for the years 2020 to 2040 it was necessary to assume a volume of surface supply that would be used within ID4 boundaries. It has been assumed that with limited infill areas remaining within the District boundary, demand within ID4 will increase from 5,500 AFY to 6,000 AFY over the next 20 years Basin Description Law CWC (b) If groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan: (2) A description of any groundwater basin or basins from which the urban water supplier pumps groundwater. ENCSD pumps groundwater from the Kern County Subbasin (No ) of the San Joaquin Valley Basin which comprises approximately 3,040 square miles. The basin is surrounded on the west by the Coast Ranges, on the south by San Emigdio and Tehachapi Mountains, on the east by the Sierra Nevada, and on the north by the Sacramento-San Joaquin Delta and Sacramento Valley. The southern portion of the basin drains internally to the Tulare drainage basin (comprised of the former Tulare, Buena Vista, and Kern Lakes). The basin is currently non-adjudicated. DWR Bulletin 118 indicates that the groundwater level in the basin (particularly in the Bakersfield area) showed decreases of 25 to 50 feet between 1970 and The prolonged drought over the last four years has likely led to greater decreases in groundwater levels. Page 6-2

34 East Niles Community Services District Urban Water Management Plan Groundwater Management Law CWC (b)...if groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan: (1) A copy of any groundwater management plan adopted by the urban water supplier or any other specific authorization for groundwater management. (2) For basins that a court or the board has adjudicated the rights to pump groundwater, a copy of the order or decree adopted by the court or the board and a description of the amount of groundwater the urban water supplier has the legal right to pump under the order or decree. The Kern County subbasin is a subbasin to the San Joaquin Valley Groundwater Basin and is a non-adjudicated basin and there is currently no groundwater management plan associated with the subbasin. However, under the provisions of the newly enacted Sustainable Groundwater Management Act (SGMA) (California code 10720, et seq), local agencies have the have the ability to develop and adopt groundwater management plans, which are tailored to the resources and needs of their communities. The intent of the SGMA is to: Provide for the sustainable management of groundwater basins. Enhance local management of groundwater consistent with rights to use or store groundwater and Section 2 of Article X of the California Constitution. It is the intent of the Legislature to preserve the security of water rights in the state to the greatest extent possible consistent with the sustainable management of groundwater Establish minimum standards for sustainable groundwater management Provide local groundwater agencies with the authority and the technical and financial assistance necessary to sustainably manage groundwater. Avoid or minimize subsidence. Improve data collection and understanding about groundwater. Increase groundwater storage and remove impediments to recharge Manage groundwater basins through the actions of local governmental agencies to the greatest extent feasible, while minimizing state intervention to only when necessary to ensure that local agencies manage groundwater in a sustainable manner. The District is currently in the process of forming a Groundwater Sustainability Agency (GSA) with surrounding water providers and retailers for the purpose of developing and adopting a Groundwater Sustainability Plan (GSP) pursuant to the regulations enacted by the SGMA Overdraft Conditions Law CWC (b)(2) For basins that have not been adjudicated, (provide) information as to whether the department has identified the basin or basins as overdrafted or has projected that the basin will become overdrafted if present management conditions continue, in the most current official departmental bulletin that characterizes the condition of the groundwater basin, and a detailed description of the efforts being undertaken by the urban water supplier to eliminate the long-term overdraft condition. DWR Bulletin 118 for the Tulare Lake Hydrologic Region, lists the estimated total subbasin inflow as 1,534,000 AF and the total subbasin outflow as 1,400,300. Page 6-3

35 East Niles Community Services District Urban Water Management Plan Historical Groundwater Pumping Law CWC (b)...if groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan: (3) A detailed description and analysis of the location, amount, and sufficiency of groundwater pumped by the urban water supplier for the past five years. The description and analysis shall be based on information that is reasonably available, including, but not limited to, historic use records. ENCSD pumping within the ENCSD boundary. As shown in Table 6-1, the District s present well capacity (9,300 AFY) exceeds existing demand. Table 6-1 Retail: Groundwater Volume Pumped Supplier does not pump groundwater.

Groundwater Type Location or Basin Name Alluvial Basin 6.3 Surface Water San Joaquin Valley Groundwater Basin - Kern County Subbasin TOTAL 4,252 4,771 4,414 3,760 2,929 ENCSD has evaluated options for obtaining a self-supplied surface water source. At present, the District does not use nor plan to use a self-supplied surface water as part of its water supply. Surface water used by the District is supplied by the KCWA and has been reported in Section 6.1 under Purchased or Imported Water. 6.4 Stormwater The District recognizes the benefits storm water reuse but does not currently participate in a storm water reuse program. The District will continue to examine available water reuse options including beneficial use of storm water in order to alleviate possible strains on its water supply needs. 6.5 Wastewater and Recycled Water Recycled Water Coordination Law CWC The plan shall provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier. The preparation of the plan shall be coordinated with local water, wastewater, groundwater, and planning agencies that operate within the supplier s service area. East Niles Community Services District manages wastewater collection for its customers, but treatment is provided by the City of Bakersfield at Wastewater Treatment Plant No. 2. ENCSD understands that wastewater recycling is an important tool to use in reducing demands upon the groundwater basin as well as surface water supplies. The District is a member of a wastewater Technical Advisory Committee, along with the City of Bakersfield and Kern Sanitation Authority, which discusses options for increases in the use of recycled water. At present, the District is not in a position to implement recycled water use on its own as no sources are available. Page 6-4

36 East Niles Community Services District Urban Water Management Plan Wastewater Collection, Treatment and Disposal Law CWC a) (Describe) the wastewater collection and treatment systems in the supplier s service area, including a quantification of the amount of wastewater collected and treated and the methods of wastewater disposal. CWC (b) (Describe) the quantity of treated wastewater that meets recycled water standards, is being discharged, and is otherwise available for use in a recycled water project. ENCSD provides sewer collection customers within its service area boundary. Collected sewage is sent to the City of Bakersfield s Wastewater Treatment Plant No. 2 where it is treated to a secondary level and then used as an irrigation supply for restricted farming uses. It is expected that this practice will continue in the future and aid the groundwater basin through in lieu recharge. Exact wastewater production records for ENCSD are not possible to calculate due to the fact that the City of Bakersfield, Kern Sanitation Authority, and the District all share common trunk lines. However, in order to estimate the wastewater production in the District, the per capita wastewater generation was estimated to be 100 GPD. Based on this estimate, the District should have produced approximately acre-feet per day (AFD) or 3.54 million gallons per day (MGD) of wastewater in Table 6-2 provides the estimated volume of waste water collected by the District s collection system during Table 6-2 Retail: Wastewater Collected Within Service Area in 2015 There is no wastewater collection system.

Page 6-5

37 East Niles Community Services District Urban Water Management Plan CWC (g) (Provide a) plan for optimizing the use of recycled water in the supplier s service area, including actions to facilitate the installation of dual distribution systems, to promote recirculating uses, to facilitate the increased use of treated wastewater that meets recycled water standards, and to overcome any obstacles to achieving that increased use. The District is relying upon its continued participation in the City of Bakersfield Regional Wastewater Treatment facility (WWTP No. 2) for disposal of treated effluent. However, the District is also participating in ongoing discussions with the City of Bakersfield regarding expansion of the WWTP. Recycled water facilities will be a topic of discussion with the City in any proposed expansion. Until discussions with the City progress, it is not possible to project which types of incentives may be employed (see Table 6-6). Table 6-6 Retail: Methods to Expand Future Recycled Water Use Supplier does not plan to expand recycled water use in the future. Supplier will not complete the table below but will provide narrative explanation. 6-7 Provide page location of narrative in UWMP Expected Increase in Recycled Name of Action Description Planned Implementation Year Water Use 6.6 Desalination Water Opportunities Law Total 0 CWC (h) Describe the opportunities for development of desalinated water, including, but not limited to, ocean water, brackish water, and groundwater, as a long-term supply ENCSD is not located near the ocean or any significant brackish groundwater supplies. However, ENCSD has in the past preliminary evaluated the feasibility of treating impaired groundwater supplies on the west side of the San Joaquin Valley for potential treatment and delivery to a water storage district on the west side of the valley. If this type of project were developed, it is presumed that an equivalent amount of State Water Project water from a west side district could then be delivered to ENCSD. At present the implementation of such a program is not believed to be financially feasible. 6.7 Exchange or Transfers Law CWC (d) Describe the opportunities for exchanges or transfers of water on a short-term or long-term basis. ENCSD is not currently engaged in any water transfers or exchanges. However, the District does benefit from KCWA s involvement in multiple transfer and exchange opportunities that contribute to the reliability of the District s KCWA surface water supply. 6.8 Future Water Projects Law CWC (g) The urban water supplier shall include a detailed description of expected future projects and programs that the urban water supplier may implement to increase the amount of the water supply available to the urban water supplier in average, single-dry, and multiple-dry water years. The description shall identify specific projects and include a description of the increase Page 6-6

38 East Niles Community Services District Urban Water Management Plan in water supply that is expected to be available from each project. The description shall include an estimate with regard to the implementation timeline for each project or program. The District currently relies on both surface water and groundwater for its water supply. The District s 2008 Water Master Plan identified the need for multiple new wells to meet projected demands through 2030 as well as distribution pipelines, booster pumping facilities, and storage to meet operational and fire storage requirements. However, with the KCWA Treatment Plant Expansion completed, the amount of surface water available to ENCSD has increased for areas within ID4. Two things that are not accounted for in the Water Master Plan are the reduction in water use that has occurred the last two years and the reductions that are required by the Water Conservation Bill of In light of the slowdown in development activity that has occurred, the build out of facilities identified in the Water Master Plan is anticipated to be stretched over a longer period of time. Therefore, as of the date of adoption of this Plan, the District has not identified or scheduled any water supply projects. However, the District will continue to pursue options for exchange of water in order to provide more options and further redundancy for the existing supplies (see Table 6-7).

40 East Niles Community Services District Urban Water Management Plan SECTION 7 WATER SUPPLY RELIABILITY ASSESSMENT 7.1 Constraints on Water Sources Law CWC (c)(2) For any water source that may not be available at a consistent level of use, given specific legal, environmental, water quality, or climatic factors, describe plans to supplement or replace that source with alternative sources or water demand management measures, to the extent practicable. CWC The plan shall include information, to the extent practicable, relating to the quality of existing sources of water available to the supplier over the same five-year increments as described in subdivision (a) of Section 10631, and the manner in which water quality affects water management strategies and supply reliability. ENCSD depends upon two main sources of water, which are surface water from KCWA ID4 and groundwater. ENCSD benefits from having multiple water sources from which to draw from during shortages. The District works diligently to build redundancy into their supplies. As previously noted, the capacity of the District s wells is in excess of their current demands even if surface water is excluded. Furthermore, the surface water supply from KCWA is in excess of the current demands excluding groundwater sources. Due to this redundancy, the District has had consistent supplies even in years when supplies would be anticipated to be inconsistent due to climactic conditions Groundwater Reliability Groundwater within the District is pumped as required to supplement demands within KCWA ID4 and to supply all areas outside of ID4. As the basin is non-adjudicated, the District has been able to pump as needed during single and multiple dry-year periods to meet all demands. Subbasin water levels have shown the ability to recover from drought conditions. It is anticipated that this capability will remain through Therefore, the District considers that their groundwater supply to be 100% in all single-dry and multiple-dry year scenarios. At present, the only factors that could be projected to impact the consistency of the District s groundwater supply would be changes in groundwater quality (due to water table decline) and limitations on pumping resulting from the GSP process under SGMA (see Table 7-0). If necessary, the District will provide wellhead treatment should water quality change. ENCSD s participation in the GSA and GSP processes is anticipated to improve the sustainability of the District s groundwater supply Surface Water Reliability KCWA has prepared a reliability analysis for the water that they wholesale to ENCSD as part of the KCWA ID4 UWMP. Their reliability analysis states the following: In single dry years, ID4 s surface water supply is constrained, but the available supply of banked water means total supplies are still well above total demands, and no delivery restrictions are necessary. Supply in multiple dry years.id4 has sufficient banked groundwater account balances to allow for more than four years of maximum-rate withdrawal. All considered, ID4 s water resources are sufficient to provide a high degree of certainty that demands can be met in single dry and multiple dry years of the most severe nature of record. Furthermore, ID4 s supply and demand comparison through the year 2040 shows supplies well in excess of demand in all multiple dry year scenarios even including an optional fourth dry year. Therefore, for the purposes of this UWMP, ENCSD has determined that their surface water supply is 100% in all single and multiple dry-year scenarios. In the event Page 7-1

41 East Niles Community Services District Urban Water Management Plan that an unanticipated surface water supply deficiency does occur the District could rely on groundwater pumping to make up the difference. Table 7-0 Factors Resulting in Inconsistency of Supply (AFY) Water supply sources Groundwater Specific source name Kern County Subbasin No Surface Water KCWA ID-4 None 7.2 Reliability by Type of Year Law Limitation quantification Legal Environmental None GSP Limitations Water quality Change due to GW Drop Climatic GW Level Drop CWC (c)(1) Describe the reliability of the water supply and vulnerability to seasonal or climatic shortage, to the extent practicable, and provide data for each of the following: (A) an average water year, (B) a single dry water year, (C) multiple dry water years. As noted in Sections and 7.1.2, District supplies have been reliable in historical average, single dry, and multiple dry year period. Thus, it is difficult to identify average, single dry, and multiple dry year periods because typical parameters like rainfall within the District do not directly determine the source reliability. For the purpose of the UWMP, the recent three-year statewide drought has been selected to represent a multiple dry year period. The two preceding years have been identified as the average and single dry years respectively (refer to Table 7-1). The reliability of water service is subject to proper operation and maintenance of the District s water distribution system and its ability to deliver the water. ENCSD s water distribution system historically has provided a very reliable level of service. A looped distribution system with isolation valves limits and minimizes service disruption. The frequency of system outages is very small due to an ambitious maintenance and replacement program. As the system is expanded the Water Master Plan is consulted. As a result, system reliability does not diminish as service is expanded into new areas. Funds to maintain and expand the system to meet the continued growth in water demand are collected through water rates and development fees which are regularly evaluated.

42 East Niles Community Services District Urban Water Management Plan 7.3 Supply and Demand Assessment Law CWC (a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and multiple dry water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional or local agency population projections within the service area of the urban water supplier. As discussed in Section 7.2, the Districts water sources are reliable. The District expects supplies to remain constant through 2040 regardless of whether those years represent average, single-dry, or multiple-dry years. The demand totals for 2020 through 2040 were calculated in Section 4.2 and include the required 20 percent reduction by Table 7-2, 7-3, and 7-4 summarize the Districts supply and demand totals in 5-year increments form 2020 to 2040 for average, single-dry and multiple-dry years. The tables demonstrate that the District has sufficient supplies to meet demands through Table 7-2 Retail: Normal Year Supply and Demand Comparison Supply totals 19,550 19,550 19,550 19,550 Demand totals 14,381 15,744 17,126 18,542 Difference 5,169 3,806 2,424 1,008 Table 7-3 Retail: Single Dry Year Supply and Demand Comparison Supply totals 19,550 19,550 19,550 19,550 Demand totals 14,381 15,744 17,126 18,542 Difference 5,169 3,806 2,424 1,008 Table 7-4 Retail: Multiple Dry Years Supply and Demand Comparison Supply totals 19,550 19,550 19,550 19,550 First year Demand totals 14,381 15,744 17,126 18,542 Difference 5,169 3,806 2,424 1,008 Supply totals 19,550 19,550 19,550 19,550 Second year Demand totals 14,381 15,744 17,126 18,542 Difference 5,169 3,806 2,424 1,008 Supply totals 19,550 19,550 19,550 19,550 Third year Demand totals 14,381 15,744 17,126 18,542 Difference 5,169 3,806 2,424 1,008 Page 7-3

43 East Niles Community Services District Urban Water Management Plan 7.4 Regional Supply Reliability Law CWC (f) An urban water supplier shall describe in the plan water management tools and options used by that entity that will maximize resources and minimize the need to import water from other regions. The District has developed and implemented many Demand Management Measures (DMM) in order to maximize its water supply. These DMM s are discussed in Section 9 and include water audit, public educational and awareness programs, incentives, and rebate programs. The District is also in the process of forming a GSA with neighboring water suppliers, retailers, and wholesalers. The intent of the GSA will be to form a GSP pursuant to the newly enacted SGMA. Regional groundwater reliability is anticipated to improve based on this collaborative effort at groundwater management. Page 7-4

44 East Niles Community Services District Urban Water Management Plan SECTION 8 WATER SHORTAGE CONTINGENCY PLANNING Law CWC (a) The plan shall provide an urban water shortage contingency analysis that includes each of the following elements that are within the authority of the urban water supplier. In 1992, in accordance with the requirements of Assembly Bill 11X, ENCSD developed a comprehensive Water Shortage Contingency Plan (WSCP). ENCSD updated the WSCP in 2015 and also issued Ordinance No setting forth mandatory water conservation requirements. A copy of the WSCP and Ordinance are included in Appendix F. 8.1 Stages of Action Law CWC (a)(1) Stages of action to be undertaken by the urban water supplier in response to water supply shortages, including up to a 50 percent reduction in water supply, and an outline of specific water supply conditions which are applicable to each stage. The WSCP identifies water conservation measures and progressive restrictions on water use to provide certainty to water users and to enable the District to control water use, provide water supplies, and plan and implement water management measures in a fair and orderly manner for the benefit of the public. The WSCP establishes three stages of drought response actions to be implemented in times of shortage, with increasing restrictions on water use in response to decreasing supplies. The WSCP includes both voluntary and mandatory rationing depending on the causes, severity, and anticipated duration of the water supply shortage. Rationing stages may be triggered by a shortage or contamination in one water source or a combination of sources or during times that a shortage is declared by the District, State, or Federal government. ENCSD potable water sources are groundwater and surface water. Because shortages overlap Stages, triggers automatically implement the more restrictive Stage. Specific criteria for triggering ENCSD s rationing Stages are shown in Table 8-1. Table 8-1 Retail Stages of Water Shortage Contingency Plan Stage Complete Both Percent Supply Reduction 1 Water Supply Condition I (Voluntary) Up to 15% Supply is 85% of normal or greater II (Mandatory) Up to 30% Supply is 70-84% of normal III (Mandatory) Up to 50% Supply is 50-69% of normal 1 One stage in the Water Shortage Contingency Plan must address a water shortage of 50%. ENCSD must provide the minimum health and safety water needs of the community at all times. The water shortage response is designed to provide a minimum of 50% of normal supply during a severe or extended water shortage or a declared emergency. 8.2 Prohibitions on End Uses Law CWC (a)(4) Additional, mandatory prohibitions against specific water use practices during water shortages, including, but not limited to, prohibiting the use of potable water for street cleaning. Page 8-1

45 East Niles Community Services District Urban Water Management Plan (5) Consumption reduction methods in the most restrictive stages. Each urban water supplier may use any type of consumption reduction methods in its water shortage contingency analysis that would reduce water use, are appropriate for its area, and have the ability to achieve a water use reduction consistent with up to a 50 percent reduction in water supply. ENCSD has included a draft No-Waste Resolution in Appendix G which includes prohibitions on various wasteful water uses such as washing sidewalks and driveways with potable water, maintaining or cleaning decorative water features, and allowing plumbing leaks to go uncorrected more than 24 hours after customer notification. Table 8-2 summarizes the restrictions and prohibitions on end uses during each stage of water shortage response implemented by ENCSD. Table 8-2 Retail Only: Restrictions and Prohibitions on End Uses Stage Restrictions and Prohibitions on End Users Additional Explanation or Reference Penalty, Charge, or Other Enforcement? I Other Public outreach for voluntary reduction in water use by 15%. No I Other Education for water conservation methods.

Only use a hand-held hose equipped with a positive shut-off nozzle or bucket to water landscaped areas, including trees and shrubs located on residential and commercial properties that are not irrigated by a landscape irrigation system. Irrigate nursery and commercial grower s products before 9 a.m. and after 6 p.m. only. Watering is permitted at any time with a hand-held hose equipped with a positive shut-off nozzle, a bucket, or when a drip/micro-irrigation system/equipment is used. Irrigation of nursery propagation beds Use only re-circulated water to operate ornamental fountains or decorative water features. Only wash vehicles using a bucket and a hand-held hose with positive shut-off nozzle, mobile high pressure/low volume wash system, or at a commercial site that re-circulates (reclaims) water on- site. Avoid washing during hot conditions (over 95 degrees) when additional water is required due to evaporation. Serve and refill water in restaurants, hotels, cafes, cafeterias, bars, or other public places where food or drink are served and/or purchased only upon request. Operators of hotels and motels shall provide guests with the option of choosing not to have towels and linens laundered daily. The hotel or motel must prominently display notice of the option in each guestroom using clear and easily understood language. No No No No No No No No No Page 8-2

No application of water to outdoor landscapes during and within 48 hours after measurable rainfall. Watering of outdoor residential and commercial landscapes will be limited to certain days of the week as follows: Residences and commercial properties with even-numbered addresses will be able to water on Sunday, Wednesday, and Friday. Residences and commercial properties with oddnumbered addresses will be able to water on Tuesday, Thursday, and Saturday. Watering of outdoor landscapes will not be allowed on Monday. Watering of outdoor landscapes will be permitted to only between the hours of 6:00 pm and 9:00 am. Commercial, industrial, and institutional properties, such as campuses, golf courses, and cemeteries, shall implement water efficiency measures to reduce potable water usage as may be required by the State of California, the State Water Resources Control Board, or other appropriate state agency. The District shall provide prompt notice to a customer whenever the District obtains information that indicates that a leak may exist within the end-user s exclusive control. The customer must repair all leaks within forty-eight (48) hours of notification by the District unless other arrangements are made with the General Manager. Penalty, Charge, or Other Enforcement? No No No No No No No No 8.3 Penalties, Charges, Other Enforcement of Prohibitions Law CWC (a)(6) Penalties or charges for excessive use, where applicable. Any customer violating the regulations and restrictions on water use set forth in the No Waste" Resolution shall receive a written warning for the first such violation. Upon a second violation, the customer shall receive a written warning and the district may cause a flow-restrictor to be installed in the service. If a flow-restrictor is placed, the violator shall pay the cost of the installation and removal. If water service is disconnected, it shall be restored only upon payment of the turn-on charge fixed by the Board of Directors. The ENCSD Board of Directors may establish a schedule of penalties for violations of the WSCP. Page 8-3

47 East Niles Community Services District Urban Water Management Plan 8.4 Consumption Reduction Methods Law CWC (a)(5) Consumption reduction methods in the most restrictive stages. Each urban water supplier may use any type of consumption reduction methods in its water shortage contingency analysis that would reduce water use, are appropriate for its area, and have the ability to achieve a water use reduction consistent with up to a 50 percent reduction in water supply. Table 8-3 summarizes the consumption reduction methods implemented by ENCSD during the varying water shortage stages. Table 8-3: Stages of Water Shortage Contingency Plan - Consumption Reduction Methods Stage Consumption Reduction Methods by Additional Explanation or Reference Water Supplier (optional) All Stages Expand Public Information Campaign Education Programs All Stages Other Demand Reduction Program All Stages Other Use Prohibitions I and II Other Voluntary Rationing III Other Flow Restriction III Other Restrict only for Priority Users III Other Mandatory Rationing 8.5 Determining Water Shortage Reductions Law CWC (a)(9) A mechanism for determining actual reductions in water use pursuant to the urban water shortage contingency analysis. ENCSD is fully metered for all customers, including separate meters for single family residences, multi-family residences, commercial, industrial, large landscapes, and all institutional/governmental facilities. The District uses the water meters to determine the consumption of water throughout the service area. Under normal water supply conditions, potable water production figures are recorded daily. Totals are reported weekly to the Senior Water Operator and monthly to ENCSD General Manager. The General Manager incorporates the information into a water supply report. During a Stage I or Stage II water shortage, monthly production figures are reported to the Senior Water Operator. The Senior Water Operator compares the monthly production to the target monthly production to verify that the reduction goal is being met. Monthly reports are forwarded to the General Manager and presented by the General Manager to the Board of Directors. If reduction goals are not met, the General Manager will notify the ENCSD Board of Directors so that corrective action can be taken. During a Stage III water shortage, the procedure listed above are followed, with the addition of a weekly production report to the General Manager. During emergency shortages, production figures are reported to both the Senior Water Operator and the General Manager regularly. During extraordinary circumstances, reports will also be provided regularly to the Board of Directors. Page 8-4

48 East Niles Community Services District Urban Water Management Plan 8.6 Revenue and Expenditure Impacts Law CWC (a)(7) An analysis of the impacts of each of the actions and conditions described in paragraphs (1) to (6), inclusive, on the revenues and expenditures of the urban water supplier, and proposed measures to overcome those impacts, such as the development of reserves and rate adjustments. ENCSD s rate structure has been set up such that all customers pay a readiness-to-serve charge and a volume of use charge. The rates are set with the intent that fixed water expenses are covered by the ready-to-serve charge and variable charges (i.e., pumping, treatment, etc.) are covered by the volume of use charge. Therefore, reductions in revenue due to conservation should also be accompanied by reductions in variable expenses incurred by the District. Any minor shortfalls if they did occur could be covered by the District s general fund and/or reserves. 8.7 Resolution or Ordinance Law CWC (a)(8) A draft water shortage contingency resolution or ordinance. The adopted water shortage contingency plan and the draft resolution to adopt the water shortage contingency plan are included in Appendices F and G respectively. 8.8 Catastrophic Supply Interruption Law CWC (a)(3) Actions to be undertaken by the urban water supplier to prepare for, and implement during, a catastrophic interruption of water supplies including, but not limited to, a regional power outage, an earthquake, or other disaster. A catastrophic event may result in a complete loss of District water supplies for a temporary period lasting from a day to a week or more. Examples of catastrophic events include earthquake, widespread power outage, contamination, long-term drought, or loss of imported supplies. Through information included in billing inserts, the District encourages its customers to be prepared for emergencies and potential interruption of District water supplies by storage of in-home water supplies. In the event of a catastrophic emergency affecting the District s water supply system, the District will cooperate with the Kern County Emergency Operations Center in recovery operations to restore water supplies to pre-emergency conditions as quickly as possible. District employees will be contacted and activated as per the District s emergency response policy. In the event of an earthquake the District will take the following actions: The system will be assessed for damage The damage will be repaired by District personnel and/or contractors In the event of a regional power failure the following actions will occur: Standby engines and power generators will be relied upon to maintain minimum pressure in the system The available District water storage will also be relied upon Page 8-5

49 East Niles Community Services District Urban Water Management Plan 8.9 Minimum Supply Next Three Years Law CWC (a)(2) An estimate of the minimum water supply available during each of the next three water years based on the driest three-year historic sequence for the agency s water supply. Table 8-4 summarizes the anticipated minimum supply for the next three years based on available supply resources. Table 8-4 Retail: Minimum Supply Next Three Years Available Water Supply 19,550 19,550 19,550 Page 8-6

50 East Niles Community Services District Urban Water Management Plan SECTION 9 DEMAND MANAGEMENT MEASURES 9.1 Demand Management Measures for Retail Agencies Law CWC (f)(a) The narrative shall describe the water demand management measure that the supplier plans to implement to achieve its water use targets pursuant to Section (B) The narrative pursuant to this paragraph shall include descriptions of the following water demand management measures: (i) Water waste prevention ordinances. (ii) Metering. (iii) Conservation pricing. (iv) Public education and outreach. (v) Programs to assess and manage distribution system real loss. (vi) Water conservation program coordination and staffing support. (vii) Other demand management measures that have a significant impact on water use as measured in gallons per capita per day, including innovative measures, if implemented CWC 526 (a) Notwithstanding any other provisions of law, an urban water supplier that, on or after January 1, 2004, receives water from the federal Central Valley Project under a water service contract or subcontract... shall do both of the following: (1) On or before January 1, 2013, install water meters on all service connections to residential and nonagricultural commercial buildings... located within its service area. CWC 527 (a) An urban water supplier that is not subject to Section 526 shall do both the following: (1) Install water meters on all municipal and industrial service connections located within its service area on or before January 1, The UWMP Act requires a discussion of Demand Management Measures (DMMs), including a description of each of the DMMs currently being implemented/scheduled for implementation, the schedule of implementation for all DMMs, and the methods, if any, ENCSD will use to evaluate the effectiveness of DMMs. ENCSD is committed to implementing water conservation programs that are economic and reasonable. The section of the California Water Code addressing DMMs was significantly modified in 2014, based on recommendations from the Independent Technical Panel (ITP) to the legislature. As a results the requirements for retail agencies were streamlined from 14 specific measures to six more general requirements plus an other category. ENCSD has addressed all Demand Management Measures (DMM) categories listed in CWC Water Waste Prevention Ordinances The District established a No-Waste Resolution in 1992, which is actively enforced. An updated draft No-Waste Resolution has been prepared by the District, see Appendix G. The District began enforcing this DMM in 1992 and plans to do so indefinitely. Since the passing of the resolution in 1992, no violations have been reported to the ENCSD Board of Directors (Board) Metering ENCSD is fully metered for all customer sectors, including separate meters for single-family residential, commercial, large landscapes, and all institutional/governmental facilities. Until the summer of 2003, ENCSD had a block rate structure, with a lifeline allotment of 12 billing units (100 cubic feet or 748 gallons) per connection per month for ¾ metered customers (larger baseline allotments were associated with larger meters). However, after the District revised their water rate structure there is no longer a baseline allotment. Instead, each customer pays a ready-to-serve charge and a unit charge for use by volume. Page 9-1

51 East Niles Community Services District Urban Water Management Plan Commercial/industrial/institutional customers are required to have fire sprinkler systems. Separate meters are required on some fire sprinkler systems, with associated monthly service charges. ENCSD will continue to install and read meters on all new services, and will continue to conduct its meter calibration and replacement program for all existing meters. ENCSD plans to continue to bill by volume of use. The District believes that having all customers metered is an effective conservation method Conservation Pricing Until the summer of 2003, ENCSD had a block rate structure. However, after the District revised their water rate structure, there is no longer a baseline allotment. Instead, each customer pays a readiness-to-serve charge and a volume of use charge. The District believes that having all customers metered is an effective conservation method because if customers must pay for all of the water they use on a volume basis they tend to watch their usage carefully. Furthermore, with volume based billing, the customers have information available to them regarding their monthly use and can more effectively plan to conserve. ENCSD will continue to install and read meters on all new services, and will continue to conduct its meter calibration and replacement program. The District will continue to bill by volume of use Public Education Outreach Public Information Programs ENCSD promotes water conservation and other resource efficiencies in coordination with the Kern County Water Agency and the Water Association of Kern County. ENCSD distributes public information through public service announcements (radio and television), bill inserts, brochures, and special events in conjunction with KCWA and WAKC. ENCSD water bills were redesigned in 2000 to show monthly use for the last billing period compared to the prior eleven months. ENCSD will continue to provide public information services and materials to remind their customers as well as the general public about water resource issues on an ongoing basis. It should be noted, that the District looks for opportunities to replace existing landscape with drought tolerant plants during routine maintenance and demonstrates drought tolerant planting options at the District headquarters. Information on drought tolerant plants is available at the District office. School Education Programs ENCSD works with the Kern County Water Agency, the Water Association of Kern County, and school districts to promote water conservation and other resource efficiencies at school facilities and to educate students about these issues. A range of grade levels are provided with educational materials, which include the following: State and County water system maps, posters, workbooks, interactive computer software, and videos. The District through KCWA has hosted tours of water facilities (e.g., the Henry C Garnett Water Purification Plant), sponsored teachers Project Water Education for Teachers (WET) training, sponsor science fairs, and sponsor water conservation contests. ENCSD will continue to implement this DMM indefinitely Programs to Assess and Manage Distribution System Real Loss Water Survey Programs for Single-Family and Multi-Family Residential Customers ENCSD offers free residential water use surveys to single-family and multi-family customers when requested by the customer. ENCSD has specifically focused on any customer who has experienced elevated water usage. It is ENCSD s goal to complete surveys for all customers who make such requests. Single-family surveys take about one hour to complete and are conducted by ENCSD staff. During the landscape portion of the survey, District personnel show the customer the location of the water meter and how to read it, measure the landscaped areas, test the sprinkler system for irrigation efficiency and distribution Page 9-2

52 East Niles Community Services District Urban Water Management Plan uniformity, teach the customer how to set the irrigation controller, develop a three-season irrigation schedule (based on soil type, evapotranspiration, and irrigation system), recommend sprinkler system repairs or improvements, and provide brochures on water efficient landscaping, design, and plants. This DMM was first implemented in 2000 and is expected to continue indefinitely. Records of savings are not kept by the District as it is extremely difficult to determine if the recommendations of the survey are being implemented by the customer. System Water Audits, Leak Detection, and Repair ENCSD has conducted water audits and leak detection and repair for many years. Since ENCSD is located in an earthquake zone, it has permanently incorporated the system water audit, leak detection, and meter calibration programs (for both production and customer meters) into its utility operations. ENCSD recognizes that as meters age they may under-register. As a result, the District developed and implemented a meter replacement program that replaces approximately 400 meters each year. ENCSD has permanently incorporated this DMM into its operations and maintenance procedures. ENCSD personnel will continue to survey mains and service lines on an on-going basis. The meter replacement program will also continue at a rate of approximately 400 meters per year. Staff uses production and consumption data records to monitor unaccounted for water losses Water Conservation Program Coordination and Staffing Support Water Conservation Coordinator The General Manager, in conjunction with the Board of Directors and committees of the Board dealing with conservation and education, acts in the role of Water Conservation Coordinator for the District. The General Manager s job description includes scheduling of the District s surface water supplies and determination of appropriate groundwater pumping and therefore the General Manager is best suited to help lead conservation efforts. The District intends to implement this DMM indefinitely. The Water Conservation Coordinator monitors wasted water within the District and notifies customers of apparent wasteful activities Other Demand Management Measures Residential Plumbing Retrofit Subject to available funding, ENCSD participates in the distribution of toilet tank leak detection tablets. Conservation savings have not been calculated by ENCSD as it is extremely difficult for the District to identify if the use of the tablets has resulted in plumbing retrofits. ENCSD will continue to implement this DMM indefinitely. High-Efficiency Washing Machine Rebate Program The District monitors available rebate programs for high-efficiency washing machines and informs their customers of the availability of rebates through public outreach (i.e., mailing, public speaking, etc.). ENCSD will continue to monitor available rebate programs with both local and national vendors. The District also includes information throughout the year in the form of Smart Tips on customer billing statements reminding customers to look for high-efficiency products when shopping for appliances such as washing machines. The District will also continue to incorporate available information into the water conservation section of the website. It is very difficult for the District to determine which customers have purchased high-efficiency appliances. Residential Ultra-low-flush Toilet Replacement Program ENCSD monitors available rebate programs associated with Ultra-low-flush toilets. The District plans includes information throughout the year in the form of Smart Tips on customer billing statements reminding customers to look for high-efficiency products when shopping for appliances such as toilets. The District will also continue to incorporate available information into the water conservation section of the website. Page 9-3
