After 12 months of construction, the Forest Knolls pump station and tank upgrade projects are near completion. Construction of the new pump station is anticipated to finish in the Fall 2009. The pump station is close to Clarendon Avenue on Christopher Drive in San Francisco’s District 7. Both the pump station and water storage tank help deliver water to residences in higher elevations in this district. The existing old building was demolished for a new reinforced concrete one. Other works include installation of two new pumps (40 hp each), sprinkler system, new electrical system, new standby generator and encasement, replacement of two hydropneumatic tanks, security fencing and monitoring systems, water quality monitoring and disinfection systems, and landscaping. The tank upgrade included the retrofit and seismic rehabilitation of the existing 100,000 gallon steel tank. A new foundation; new isolation valves and vaults, new inlet and outlet piping to maximize circulation, retaining wall, security fencing and monitoring system, and access ladders and safety platforms on the tank will be added. An access road and site improvements including erosion control and drainage, water quality improvements (sampling, disinfection); and cathodic protection and monitoring system are also a part of this project. The temporary pump station will be removed and the site will be restored. Note: Schedule and cost information shown may vary from the 2009 Approved WSIP Schedule and Budget.
