Santa Margarita Water District Pico Zone A Recycled Water Pump Station and Talega Lift Station Modifications

San Clemente, CA


PACE designed two pump stations to provide pumping at the Pico site and Talega Site to finalize the new permanent shared San Clemente connections for recycled water and wastewater respectively. PACE is reconfiguring the existing Pico Sewer Lift Station into a new multizone recycled water pump station with suction and discharge lines, flow metering, and cross-connection PRV valve.  Each Zone A pump shall have a capacity of approximately 1,500 gpm each at about 200 feet of discharge boost assuming redundancy is desired.  Two 12” discharge mains will discharge and tie into the 16” transmission main on Ave Pico, on existing and one proposed.  The Bella Colina Golf Course pump shall have a capacity of approximately 600 gpm at approximately 100 feet of discharge boost, and shall discharge through an existing 12” discharge main to an 8” transmission main in Ave Pico.  The project includes change out of existing electrical including soft starters.  A small residential grinder pumping system will also be installed and a new 1” diameter forcemain out to a street manhole shall be designed to discharge the onsite restroom flows. PACE is also re-designing the existing system with new smaller sewer pumps at the existing Talega Sewer Lift Station including new discharge lines and flow metering.  The anticipated average sewer flow into the Talega Station under the new configuration is about 0.2 MGD average and 0.6 MGD (420 gpm) peak at about +/-150’ of TDH.  The project includes change out of existing electrical including soft starters.
