Anacostia Service Area ChallengesAnacostia 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

Proposed ImprovementsAnacostia Service AreasProposed ImprovementsAnacostia 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 Ft.

Proposed ImprovementsAnacostia Service Areas, continued
Proposed ImprovementsAnacostia 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 ImprovementsAnacostia 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
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 AreasCompleted 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

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?Why Is Additional Water Storage Needed?
18
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?Why an Elevated Storage Tank?
19
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?
20
Yes, “Do Nothing” optionContinued low pressures in the service area
Added risks from a fire protection perspective
Limits future development
Are There Other Options?, continuedAre There Other Options?, continued
21
High ground elevation
Centrally located in relation to problem areas
Close proximity to existing transmission pipes
Location will support future development in Anacostia
