About This Project

West Valley Water District retained ERSC to design a water pumping station to pump from Zone 3 (North Colton/Bloomington) to Zone 4 (Northern Rialto) from Lord Ranch.


The proposed project is to provide additional pumping capacity to connect 1.0 MG Aeration Reservoir (also designed by ERSC) in Zone 3 to Zone 4 for future demand and growth.


ERSC proposed the Zone 4-3 Pumping Station to meet the District’s additional demands. The pumping station is equipped with 8 – 300 horsepower pumps capable of providing 20,860 additional gallons per minute with one pump on stand-by. At this time the design will include only 4 pumps and the remaining 4 pumps will be installed as needed.


ERSC also provided bid support services during the bidding phase and construction management services during the project construction phase.
