Anacostia Improvements

Proposed Improvements to the Water System Infrastructure in the Anacostia Area ofWashington, D.C.: 

Proposed Improvements to the Water System Infrastructure in the Anacostia Area of Washington, D.C. November 20, 2002 Prepared by Prepared for Our Customers, Council Members, Advisory Neighborhood Commissioners, and Concerned Stakeholders

Benefits from Proposed $40 Million Improvements: 

Benefits from Proposed $40 Million Improvements Maintains water quality More reliable fire protection Improved water pressure Enhanced reliability for the community Addresses water, fire, and maintenance challenges at the St. Elizabeths campus Supports future development St. Elizabeths Hospital overlooks the Potomac and Anacostia Rivers.

Anacostia Service Area Challenges: 

Anacostia Service Area Challenges Low pressure in southern Anacostia (south of W Street, SE) Low pressure at St. Elizabeths campus Under utilization of water storage at Ft. Stanton Reservoirs Old water transmission system Aging equipment and building at Anacostia Pumping Station, constructed in 1913 Fire protection

Improvements in Anacostia: 

Improvements in Anacostia North Anacostia South Anacostia

Low Water Pressure vs. High Water Pressure: 

Low Water Pressure vs. High Water Pressure Ft. Stanton Reservoirs Low pressure acceptability threshold: 35 psi Optimal water pressure: 50–80 psi

Before Conditions vs. After Conditions: 

Before Conditions vs. After Conditions 35 psi – low pressure acceptability threshold 50–80 psi – optimum water pressure Pomeroy Road

Before Conditions vs. After Conditions, continued:

Planned Improvements : 

Planned Improvements 2005 2006 Pipes 2004–2005

Proposed ImprovementsAnacostia Service Areas: 

Proposed Improvements Anacostia Service Areas Plan of Action: Construct new Ft. Stanton Pumping Station Benefits: This pumping station and the tank will boost pressure in the southern portion of Anacostia Maximize use of the storage capacity at the Ft. Stanton Reservoirs

Proposed ImprovementsAnacostia Service Areas, continued: 

Proposed Improvements Anacostia Service Areas, continued Plan of Action: Construct 2 million gallon (MG) elevated storage tank in southern portion of Anacostia Benefits: Maintains optimal pressure Provides continuous water supply during peak demand periods Provides ample fire protection storage Provides emergency reserve in the event of mechanical failure to the pumping station Proposed tank

Proposed ImprovementsAnacostia Service Areas, continued: 

Proposed Improvements Anacostia Service Areas, continued Plan of Action: Replace 6,000 feet of 20" pipe along Minnesota Avenue, from Pennsylvania Avenue to W Street Benefit: Replace low pressure-rated pipe with higher rated pipe to meet higher pressure requirements

Proposed ImprovementsAnacostia Service Areas, continued: 

Proposed Improvements Anacostia Service Areas, continued Plan of Action: Replace 4,800 feet of 20" pipe along Martin Luther King Jr. Avenue, from Milwaukee Place to Upsal Street, SE Benefit: Replaces low pressure-rated pipe with higher rated pipe to meet higher pressure requirements

Proposed ImprovementsAnacostia Service Areas, continued: 

Proposed Improvements Anacostia Service Areas, continued Plan of Action: New 5,300 feet of 24" pipe along V or W Street, from Ft. Stanton Reservoirs to Martin Luther King Jr. Avenue Benefit: Will provide a secondary feed to the Ft. Stanton Reservoirs, and a looped transmission network for better circulation

Proposed ImprovementsAnacostia Service Areas, continued: 

Proposed Improvements Anacostia Service Areas, continued Plan of Action: Replace existing Anacostia Pumping Station with new station on existing site Benefits: Replaces 1913 station, with new state-of-the-art facility Existing station will remain operational during construction with no loss of service

Completed Improvements Anacostia Service Areas: 

Completed Improvements Anacostia Service Areas Plan of Action: Rehabilitate two Anacostia elevated storage tanks: Good Hope (completed) and Boulevard Tanks (in progress) Benefits: Complete repainting improves overall appearance Improves water quality Provides improved safety features for WASA operators

Slide16: 

Proposed Improvements … At a glance Replace 6,000' of 20" pipe along Minnesota Ave., from Pennsylvania Ave. to W St. PS Rehabilitate Good Hope Road Tank (completed) Rehabilitate Boulevard Tank at Massachusetts and Alabama Avenue (not shown, currently underway) Replace existing Anacostia Pumping Station New 5,300' of 24" pipe along W St., from Ft. Stanton Reservoirs to MLK Ave. Anacostia (North) Anacostia (South) Anacostia North/South Boundary (at W Street) Construct new Ft. Stanton Pumping Station Construct new 2 MG elevated storage tank at St. Elizabeths Replace 4,800' of 20" pipe along MLK Ave. from Milwaukee Pl. to Upsal St. Pennsylvania Ave.

Slide17: 

Increased water pressure To provide additional supply during peak usage periods For fire fighting purposes Emergency reserve in the event of mechanical failures in the system Additional capacity to support economic development Why Is Additional Water Storage Needed?

Slide18: 

Relies on gravity to maintain pressures Minimal mechanical working parts involved and is less vulnerable to mechanical breakdowns Less vulnerable to power failure Emergency reserve for system outages Does not make noise or emit fumes More reliable fire protection Less costly to operate and maintain Lifespan is 50+ years Why an Elevated Storage Tank?

Are There Other Options?: 

Yes, a pumping system. There are major disadvantages It’s mechanical and less reliable Increased potential for failure Requires complex multiple pump operations – more wear and tear Requires a more comprehensive back-up source of power (generator) Potential for “water-hammer” that can cause pipe breaks Additional noise Are There Other Options?

Are There Other Options?, continued: 

Yes, “Do Nothing” option Continued low pressures in the service area Added risks from a fire protection perspective Limits future development Are There Other Options?, continued

Why at St. Elizabeths?: 

High ground elevation Centrally located in relation to problem areas Close proximity to existing transmission pipes Location will support future development in Anacostia Why at St. Elizabeths?

Other Anacostia Projects: 

Other Anacostia Projects Plan of Action: Continue ongoing programs Eliminate cross connections Eliminate dead end water pipes Replace old valves Rehabilitate water pipes

Project Costs for Improvements in Anacostia: 

Project Costs for Improvements in Anacostia $ (in millions) Rehabilitate Good Hope and Boulevard Lane Tanks 0.9 Replace Anacostia Pumping Station 14.6 New Ft. Stanton Pumping Station 4.7 Replacement of pipes 9.1 24" reinforcing pipes 4.1 2 MG Anacostia elevated storage tank 5.9 Total 39.3
