1 Arlington County, Virginia WATER AND SEWER INFRASTRUCTURE PROGRAMS Program Description This program provides and maintains water delivery, sanitary sewer collection, and wastewater treatment systems that provide high quality water and sewer services and products. This program has been established to ensure that water and sewer services are available to all residents in Arlington's service area and that the Water Pollution Control Plant (WPCP) meets model discharge standards. Program Summary The Capital Improvement programs for the water distribution and sanitary sewer collection systems provide funding for both expansion of capacity for the future growth of Arlington County and the preservation of assets through rehabilitation and replacement (maintenance). Expansion projects typically increase capacity while assets are preserved through the nonexpansion category. The programs are categorized into three areas: water expansion, sewer expansion, and water/sewer maintenance capital. The water and sewer expansion programs focus on projects required to provide for the future projected land use in Arlington County by the year Estimation of the maximum expected land use development in the county, termed "build out," based on the land use types and densities in the County land use plans is used to determine water and sewer demand. The expansion projects are identified and prioritized in the Water Distribution System Master Plan and the Sanitary Sewer Collection System Master Plan. The Water System Master Plan is currently being updated with a targeted completion of fall The Sanitary Sewer System Master Plan was last updated in 2002 with an update planned to start in Some of the water projects identified in the Water Distribution System Master Plan have already been programmed into the CIP, including the Gravity Transmission Mains, Minor Hill Yard Piping, North Edison Street and a number of smaller projects. Projects identified in the Sewer Collection System Master Plan and included in this CIP include the Potomac Interceptor Phase II, Spout Run and a number of smaller projects. Both the water and sewer expansion projects are typically in the CIP for a number of years to build up funding for construction. When projects are initially funded, an alignment study is done. Funding in later years provides for preliminary engineering, final design and construction. With each step of the process the scope of the projects and funding needs become more defined. The Maintenance Capital program focuses on projects that rehabilitate and replace existing water distribution and sanitary sewer collection infrastructure. The programs for maintenance capital are outlined in the Water Distribution System and the Sanitary Sewer Collection System Master Plans. This is done for the water distribution system by programs that clean and line water mains, rehabilitate and replace valves, and rehabilitate water storage tanks. The Water Distribution Master plan recommends replacement and rehabilitation of water mains based on asset management best practices. The requested funding will be modified as more data is collected and analyzed on the condition of water mains over future CIP s. The sanitary sewer collection system is addressed by programs that rehabilitate and replace sewer mains under the infiltration and inflow program, rehabilitate large diameter sewer mains, and replace gravity sewers and sewer force mains. Other categories in this program pay Arlington County s share of the capital expenses at the Washington Aqueduct, enhance our water meter reading capabilities, and fund the acquisition of a new and upgraded technology such as asset management, work order, utility billing and project tracking for the water distribution and sewer collection systems. The Water Pollution Control Bureau (WPCB) Capital Improvement Program directly supports Arlington's vision for a world class sustainable community as well as the Bureau s mission of safely and cost-effectively protecting the public health and environment. The 10-year program provides for planning to secure a world class wastewater treatment facility that enhances attractive residential neighborhoods, and promotes an environmentally friendly, sustainable community. This program encompasses both expansion and non-expansion projects. The expansion and non-expansion Capital Improvement programs for the Water Pollution Control Plant (WPCP) and wastewater lift/metering stations systems provide funding for both expansion of capacity for the future growth of Arlington County and the preservation of assets through upgrades and timely rehabilitation or replacement, respectively. Expansion projects typically increase capacity, while assets are preserved and/or upgraded through the non-expansion category. F-1

2 The WPCP expansion program focuses on projects required to provide for the future projected land use in Arlington County such that sufficient capacity will be available past the year This demand was met in CY 2010 by a number of projects incorporated into the Master Plan 2001 project (MP01) that expanded the plant to the ultimate build out capacity of 40 MGD (million gallons per day). Barring regulatory changes, no further expansion projects to increase capacity are anticipated at this time, and therefore no expansion projects are anticipated in the upcoming 10-year CIP cycle. The non-expansion program focuses on projects that rehabilitate, replace, and/or upgrade existing WPCP infrastructure, including process control/automation, to ensure that the facility can safely protect the public health and the environment by reliably maintaining continuity of service and simultaneously meeting the permit requirements. For this 10-year cycle of the CIP, funding for the upgrade of three secondary clarifiers is included in the WPCP non-expansion capital program to ensure reliable treatment, minimize the probability of permit violations and bypasses, and meet the Class 1 Reliability permit requirement. Additionally, the solids handling portion of the Plant was not upgraded during MP01 and a number of pieces of equipment are well beyond their useful life and in need of timely replacement with more efficient and reliable technologies. DES staff is working on an update to the Water Pollution Control Plant Master Plan, which will include an evaluation of the age and condition of the existing solids infrastructure, a look ahead to future anticipated regulatory changes both on the solids side and for disinfection, and the development of replacement cycles for the Process Control System s hardware and software. A highlevel estimate of the upgrades that are needed immediately are incorporated into the FY 2015 FY 2024 CIP, while the longer-range upgrades will be included in future CIPs as appropriate. Also included in the non-expansion program are annual repairs and replacement of current equipment and infrastructure at the plant and 15 pumping and metering stations. Plant nonexpansion capital also funds Arlington's pro-rata share of improvements to the Blue Plains wastewater treatment plant and the conveyance infrastructure. F-2

6 WATER AND SEWER INFRASTRUCTURE Sanitary Sewer System Improvements WATER AND SEWER INFRASTRUCTURE CIP Program Description The Sanitary Sewer System Improvements Program addresses the capacity of the sanitary sewer system. There are 465 miles of sewer mains in the County s system. These projects ensure the sewer system maintains adequate capacity to support residential and commercial growth. Infrastructure availability fees paid by developers and utility user fees fund these projects. Master Plan Impact These projects are consistent with the plans, policies, and objectives of the Sanitary Sewer Collection System Master Plan, adopted in December of Projects Columbia Pike - George Mason to Oakland: This project involves construction of a new 12-inch sanitary sewer in Columbia Pike to reduce the risk of sanitary sewer backups. The existing 8-inch sewer is undersized and needs to be upsized for future development and constructed in a location that won't be in conflict with the future street car alignment. This project affects the Alcova Heights and Douglas Park neighborhoods. A portion of this project was included as "Columbia Pike - S Oakland St to S Quincy St" in the prior CIP, with a total estimate of $0.8 million. Timing of construction has been pushed out two years since the last CIP and the scope of the project has expanded, leading to a new estimate of $1.2 million. Columbia Pike/Rosslyn/Crystal City Sewers: Funding to upsize sewers for redevelopment. Projects are to be identified as development occurs on Columbia Pike and in Rosslyn and Crystal City. In the prior CIP, $530,000 was projected for FY 2015 spending, but the current estimate has increased to $868,000 based on increased development and to coordinate with other projects in the CIP. Improvements for Development: This project provides funding for small segments of sewer main installation and other work directly associated with development work. This funding covers mains necessary for completion of a block where the developer is only responsible for work immediately on the frontage of the site. This may also cover work to abandon existing mains in prior developments. When modeling indicates a need for larger sewer mains, but the development requiring the extra flow is by-right, this funding may be used to do entire projects. This project affects various neighborhoods throughout the County, but no work is projected for FY North Abingdon Street, Wilson Boulevard to North Carlin Springs: Homes in the project area had sanitary sewer backups during the June 2006 rainstorm due to higher than expected infiltration and inflow from upstream areas. The project area has two 18-inch sewers, one built in 1935 and the other in This project will replace a portion of the existing 18-inch sanitary sewer built in 1935 with a new 27-inch sanitary sewer. The project will increase sanitary sewer capacity to help prevent sewer backups during major storm events and replace an aging sanitary sewer main with a larger pipe. This project, which affects the Bluemont neighborhood, was included in the prior CIP, but timing of construction has been pushed out a year. North Sycamore Street: This project involves the upsizing of an existing sanitary sewer in North Sycamore Street from Route 66 to Lee Highway. The existing main is undersized and was identified in 2002 Sanitary Sewer Collection System Master Plan. Flow monitoring is in progress to determine the limits of capacity improvements needed. This project, which affects the Arlington-East Falls Church neighborhood, was included in the prior CIP, but construction has been pushed out two years. F-6

7 South Troy Street at South Glebe Road: This project reduces the risk of sanitary sewer backups at the low lying area of South Troy Street at South Glebe Road. The project affects the Long Branch Creek neighborhood. It was included in the prior CIP, but construction has been pushed out a year in the current schedule. Spout Run: The Spout Run sewer that runs between Spout Run and Rosslyn under the North Highlands neighborhood is over 100 feet deep in some areas. This sewer needs to be evaluated for the construction of a back-up sewer for redundancy and maintenance purposes. This project was included in the prior CIP; the timing of expenditures has been pushed out one year in the current schedule. F-7

8 WATER AND SEWER INFRASTRUCTURE Sanitary Sewer System Improvements WATER AND SEWER INFRASTRUCTURE CIP Potomac Interceptor Phase 1 - Junction Structure Project Description This project entails construction of junction structure 18 south of Memorial Drive to connect the existing 36-inch sewer to the new 48-inch, and abandonment of the existing 36-inch sewer between Memorial Drive and Columbia Pike. This work will complete the Potomac Interceptor Phase 1 project. Project Justification Construction of a larger diameter sewer will provide more capacity for development in the Rosslyn area and reduce the risk of sanitary sewer backups and overflows. Changes from Prior CIP This work was included in the prior CIP within the "Potomac Interceptor Phase 1" project. More recently a separate project was established for this portion of work. We anticipate the junction structure work being completed in FY15. F-8

10 WATER AND SEWER INFRASTRUCTURE Sanitary Sewer System Improvements WATER AND SEWER INFRASTRUCTURE CIP Potomac Interceptor Phase II Project Description This project will construct a parallel sanitary sewer to the 54-inch Potomac Interceptor located in S. Joyce Street and Army Navy Drive. This project will add redundancy to the current interceptor, which carries 40 percent of the County s sewage and has no parallel line. This project impacts the Aurora Highlands and Foxcroft Heights neighborhoods. Project Justification Phase II will provide additional capacity, and system reliability and redundancy. The newly constructed line will operate in parallel with the existing line. Changes from Prior CIP Timing of construction has been pushed out two years from the prior CIP. F-10

14 WATER AND SEWER INFRASTRUCTURE Water Distribution WATER AND SEWER INFRASTRUCTURE CIP Program Description The major focus of the Water Distribution System 10-year capital program is implementation of the Water Master Plan. The Water Master Plan update is expected to be completed in fall 2014, at which time it will be publicly reviewed and presented to the County Board. Many of the County s water mains were built in the 1930s, 1940s, and 1950s, and are approaching or at the end of their life expectancy. A number of water projects have already been programmed into the CIP to address future growth and increase the rate of water main rehabilitation/replacement to keep up with aging infrastructure. Many of the projects listed here appeared in prior CIPs, because projects are typically in the CIP for a number of years to build up funding for construction. The proposed CIP includes $8.861 million for gravity transmission mains; $5.825 million for construction of 10,800 linear feet of water main on North Harrison Street to provide redundancy and improve water pressure in the Ballston area; $5.0 million for Improvements for Development; and other projects as detailed below. Master Plan Impact These projects are consistent with the plans, policies, and objectives of the Water Master Plan, originally adopted in 1992, and with an update expected to be completed in fall Projects 18th Street South - Fern Street to Midblock: Construction of an 8-inch water main to complete a loop, which improves reliability and flow to an area that is currently served by a dead end water main. This is a new project for the FY FY 2024 CIP. Army Navy Country Club Access Road to 23rd Street South: Construction of 3,500 feet of 20-inch water main to provide redundancy to the Crystal City area. This project affects the Arlington Ridge neighborhood. This project appeared in the prior CIP with the same cost estimate, but the FY 2015 funding request has been reduced from $800,000 to zero (existing balances will be used instead). The project is funded by infrastructure availability fees (developer contributions) and Utilities Capital. Army Navy Drive at South Joyce Street: Construction of a 16-inch water main and pressure regulator valve upsizing. This project provides additional water main transmission capacity to the Crystal City area. The affected neighborhoods are Arlington Ridge and Aurora Highlands. The timing of expenditures has been pushed out two years from the prior CIP, and the funding schedule has changed from Utilities Capital to General Obligation Bonds. Columbia Pike - Orme St to Army Navy Drive: This project is to upgrade an existing 12-inch water main to a 16-inch in Columbia Pike from Washington Boulevard to the Air Force Memorial, then across I-395 to Army Navy Drive. This is a new project for the FY15 - FY24 CIP. Columbia Pike - Taylor to Oakland: This project will replace an existing 12-inch water main built in 1927 which services various neighborhoods. In the prior CIP, this project was titled "Columbia Pike - Wakefield to Oakland." The portion of water main from Wakefield to Taylor has been completed. Crystal Drive to 6th St South along RF&P Railroad: This project will install approximately 900 linear feet of new 12-inch water main from the end of South Clark Street at the RF&P railroad to the intersection of 12th Street South and Crystal Drive. The project provides looping of water system in order to improve reliability and flow to a developing area that is F-14

15 currently served by a dead end water main. In the prior CIP, this project was listed as "300 Block of 10th Street South & Crystal Drive." Timing of construction has been pushed out two years from the prior CIP. Edison Street / Carlin Springs Road: Funding for 8,900 feet of 16-inch water main from North Edison and 10th Street to Arlington Boulevard to provide redundancy and improve fire flow. This project impacts various neighborhoods throughout the County. Fort Barnard Supply Main: Construction of 4,500 feet of 12-inch water main, running between the intersection of Columbia Pike and South Quincy Street to the Fort Barnard storage facility. This project will provide a larger water main that will improve fire flow to the Douglas Park neighborhood and improve flow capacity to and from Fort Barnard pumping station. The neighborhoods impacted are Douglas Park and Nauck. The current plan is to fund this project primarily with General Obligation Bonds from the 2008 Referenda. Fort Myer Heights Improvement: This project constructs a 12- inch water main crossing Route 50 in order to improve fire flow and system reliability in the Fort Myer Heights neighborhood. This project was not included in the prior CIP. Improvements for Development: This funding covers mains necessary for looping or completion of a block where the developer is only responsible for work immediately on the frontage of the site. This may also cover work to abandon existing mains and the completion of loops in prior developments. When modeling indicates a need for larger water mains, but the development requiring the extra flow is by-right, this funding may be used to do entire projects. The Water System Master Plan indicates the need for this type of funding to ensure a looped water system for redundancy and adequate transmission capacity to developments. This funding was in the prior CIP; the FY15 funding request has been reduced to zero because existing balances will be used for this work. Minor Hill Pump Station Improvement: This project upgrades the motor control center to replace outdated controllers and electrical equipment. It includes replacement of pumps and motors to provide for increased capacity and more energy efficiency. This is a new project for the FY FY 2024 CIP and will be funded by Utilities Capital Fund. Minor Hill Yard Piping: This project entails construction of a water main through the Minor Hill Reservoir site. It connects to the 36-inch water main that was built with the Williamsburg Boulevard Water Main that ended at the intersection of 35th Street North and Powhatan Street. The new main continues through the site to Williamsburg Boulevard and North Sycamore Street. The main connects to the valve vaults for the water storage tanks on site. This project was in the prior CIP, but funding schedule has changed from developer contributions to primarily GO Bonds. The cost estimates went up because a portion of the reservoir supply main has been added and because the revised plan allows for remote opening and closing of valves. New River Crossing: Funding for a study of the best route to provide a backup water supply to Arlington County. The study will explore the feasibility of construction of an additional water main crossing the Potomac River. This potential water main will provide additional capacity to help ensure an adequate water supply if the existing 48-inch main is out of service. This project is new for the FY15 - FY24 CIP. North Vietch Street at Lee Highway: Construction of a new pressure regulator to replace the existing one that is located in the travel lanes of Lee Highway. This will allow for safer access during regular maintenance and emergency situations. This is a new project for the FY FY 2014 CIP. Old Dominion Drive - North Thomas Street to Lorcom: Construction of a new 12-inch water main in Old Dominion Drive from North Thomas Street to Lorcom Lane. The neighborhoods impacted are Donaldson Run and Waverly Hills. The timing of construction has been pushed out two years to FY15 from the prior CIP, which showed construction beginning in FY13. Also, the funding schedule has shifted from Utilities Capital to primarily GO Bonds. South Monroe - 12th to Columbia Pike: Construction of an 8-inch water main to complete a loop, which improves reliability and flow to an area that is currently served by a dead end water main. This is a new project for the FY FY 2024 CIP. Wilson Blvd - 10th to Clarendon Circle: Replacement of an old 8-inch water main in conjunction with a street improvement project. F-15

16 WATER AND SEWER INFRASTRUCTURE Water Distribution WATER AND SEWER INFRASTRUCTURE CIP Gravity Transmission Mains - B1 Project Description This project provides water mains to back up existing transmission capacity through the County s Gravity One pressure zone. B1 will provide an additional connection for the Lee Station water storage and pumping station. Exact locations for B2 and B3 are unknown at this time, but will parallel the 36 inch mains traveling North-South. Project Justification The current Water Distribution Master Plan identifies a project to provide a second feed to the Lee Station Water Pumping and Storage Facility. This will be a part of this proposed project that will also provide backup and additional transmission capacity through our primary pressure zone, serving Rosslyn, Clarendon, Virginia Square and parts of Ballston. Changes from Prior CIP Timing of expenditures has been pushed out one year from the prior CIP. This project was titled "Gravity Transmission Mains" in the previous CIP. The work has since been broken out into two projects: "Gravity Transmission Mains - B1" and "Gravity Transmission Mains - B2 & B3 because the project spans a number of years. The project will be implemented gradually as the County is built out. Phasing the project will allow each piece of main to continue to function on its own due to where it ties into the existing system. Also, phasing the project allows funding needs to be spread. F-16

23 WATER AND SEWER INFRASTRUCTURE WPCP Non-Expansion WATER AND SEWER INFRASTRUCTURE CIP Biosolids Projects Project Description This is a new project for the FY15 - FY24 CIP. The 2001 Master Plan included recommended upgrades to the solids handling processes, which were not implemented at the time due to higher priorities taking precedent. Several processes are now beyond their useful life and in need of replacement. Some potential projects include primary clarifiers internal mechanisms, scum concentrator replacement, gravity thickener upgrades, dissolved air flotation thickener replacement, bar screens upgrades, and lime transfer equipment replacement. The current estimate of $15M for these six projects is a conservative value based on the high level of unknowns at this early stage in the process. The 2014 Master Plan will include a condition assessment step, which will further refine the funding needs for these projects. This project impacts the Arlington Ridge and Aurora Highlands neighborhoods. Project Justification Solids handling processes were constructed anywhere from the 1950s to the 1990s, and many are now out of tolerance. In many cases, more effective technology is available that would reduce the need for maintenance and be more energy efficient. F-23

28 WATER AND SEWER INFRASTRUCTURE WPCP Non-Expansion WATER AND SEWER INFRASTRUCTURE CIP Improvements to Eads St Property Project Description This funding is for improvements to a property near the Water Pollution Control Plant that the County purchased in March These improvements include replacement of the membrane roof, anticipated to take place in FY15. This facility serves as the plant's off site warehouse, and is used for storage of larger and less frequently used items. Additionally, Arlington Transit (ART) has some offices within the facility. Per a memorandum of understanding dated November 23, 2011, the Transit Bureau contributes toward the cost of the site. Funds are required to properly maintain this facility. Occasional capital improvements will need to be made, such as replacement of the roof.

The additional $300,000 in FY15 is for replacement of the roof. The additional $400,000 in FY16 is for anticipated work on the retaining wall. Notes on Funding Schedule The Transit Bureau will contribute 16.8 percent of applicable capital costs at the Eads Street facility, consistent with its share of the space used there. The Inter-Jurisdictional (IJ) Partners also share in a portion of the capital costs at the facility. Both Transit Bureau and IJ Partner contributions are included in 'Other Funding'. F-28

29 WATER AND SEWER INFRASTRUCTURE WPCP Non-Expansion WATER AND SEWER INFRASTRUCTURE CIP Secondary Clarifiers Project Description This is a new project for the FY15 - FY24 CIP. This project entails the rehabilitation and / or replacement of secondary clarifiers 1, 2, and 3, which is necessary to restore the tanks to full working condition. This may involve replacement of the internal mechanisms or full structural replacement, depending on the results of a preliminary engineering study expected to be completed in the next year. The CIP investment shown represents full structural replacement. Project Justification The tanks were originally built in the 1960s and are no longer functioning as designed. The Plant's permit requires a certain level of redundancy, which is currently not being met. F-29

31 WATER AND SEWER INFRASTRUCTURE WPCP Non-Expansion WATER AND SEWER INFRASTRUCTURE CIP WPCP Maintenance Capital Project Description The Water Pollution Control Plant (WPCP) Non-expansion Capital Program provides annually for the repair and replacement of current equipment and infrastructure at the plant and 15 stations (including 11 pumping stations, two ejector stations, and two meter stations). Major components of this program include refurbishing or replacing equipment to prevent premature failure, as well as infrastructure improvements and automating treatment processes to increase efficiency. Project Justification Maintaining existing plant assets ensures that process equipment will perform and meet or exceed its estimated useful life, and that plant performance will meet regulatory operating limits. Changes from Prior CIP FY15 through FY17 were reduced from $4 million per year to $2 million per year (the additional $2 million per year had been a placeholder for larger projects yet to be defined). In the prior CIP, this line item was titled "WPCP Non-expansion Capital". F-31
