The U.S. Army Corps of Engineers, Baltimore District (NAB), has been tasked to solicit for and award construction services for Backwash Water Tanks Improvements at the Washington Aqueduct in Washington, DC. The proposed project will be a competitive, firm-fixed-price, contract procured in accordance with FAR 14, Sealed Bidding, via an Invitation for Bid (IFB). Total Small Business set-aside and NAICS 237110, size standard of $39.5 million. The Washington Aqueduct provides potable water to approximately one million people in the District of Columbia and Northern Virginia.� As part of the water treatment and supply system, the Washington Aqueduct maintains and operates the Dalecarlia and McMillan Water Treatment Plants (WTPs). As part of the water treatment and supply system, the Dalecarlia Water Treatment Plant (WTP) operates dual media filters for water filtration and purification purposes. When the filters are in use, the pressure loss across the media gradually increases and eventually the filter must be cleaned (backwashed) in order to continue functioning within the specified water quality limits. During the filter backwash process, high volumes of water are used to fluidize the filter media and release the trapped solids. At the Dalecarlia WTP, there are two wash water storage tanks known as the Underground Tank and the Elevated Tank, respectively. Wash water is supplied to the wash water storage reservoirs through an altitude valve, located in the Dalecarlia Pumping Station, which simultaneously supplies water to each of the tanks through 24� and 30� cast iron water mains. Wastewater from the backwash process is recycled to the Dalecarlia Forebay via a subsurface Backwash Recovery Pumping Station (BWPRS). The BWPRS operates two centrifugal pumps, which are critical to the Dalecarlia WTP environmental permitting compliance. The project consists of modifying both the supply and waste backwash facilities to restore their infrastructure, improve reliability and address sanitary deficiencies to include: construction of a drain outlet structure, the installation of a subsurface waterproofing membrane, the replacement of tank corrosion protection system, the installation of new electrical switchgears, variable speed drives, transfer switches, etc., the rehabilitation of altitude valves and the replacement of valves, actuators and actuator control systems.
