Improvements to the existing Effluent Flushing Water (EFW) pumping and piping system are necessary to deliver adequate flow and pressure for the process and flushing water uses as part of the Wet Weather Expansion Project at the ALCO SAN Wastewater Treatment Plant. The existing EFW pump station is congested in terms of pumps and piping and is configured in such a fashion that flows conveyed to and from the pumps may present operational challenges and flow distribution issues.

This contract will include the further development of the EFW system including new effluent water pumps, motor control centers and system wide layouts of the high service and low service piping networks.
