Update for MWRA Alewife Brook Pump Station
Rehabilitation Project
(MWRA Contract 6797)
 MWRA's Alewife Brook Pump Station in Somerville was constructed in 1951  About this Project: The Alewife Brook Pump Station Rehabilitation Project (MWRA Contract 6797) will improve the operating capacity and reliability of a sewer station that pumps wastewater flows from Arlington, Belmont, Cambridge, Medford and Somerville through the North Metropolitan and North Metropolitan Relief Sewers toward the Deer Island Treatment Plant. A First in Climate Change Resilience: The rehabilitation of the Alewife Brook Pump Station is the first MWRA project to incorporate new measures to protect equipment and facilities from the affects of potential climate change. This project is important step in MWRA's long-term efforts to protect the sewer system's overall ability to operate during wet weather events and to recover from them.  The Alewife Brook Sewer Rehabilitation Project will provide flood Work in Somerville: Under MWRA Contract 6797, MWRA's contractor, Barletta Engineering Corporation, will make major operational and structural improvements to the Alewife Brook Pump Station. Existing sewer pumps, original to the 1951 station, no longer operate with as-designed efficiency. They will be replaced by two, higher-capacity wet-weather pumps and a dry-weather pump, with a third wet-weather pump available for standby use. Other operational improvements include the replacement of motors, gear drives, controls, screens, sluice gates and generators. The Alewife Brook Pump station's HVAC systems, paint, roofing and insulation will also be updated and new flow meter will be installed on the Alewife Brook Conduit.
