The Huntington Beach Pump Station Urban Runoff Diversion Project was one of four channel sites chosen for the Urban Runoff Diversion Project within the Talbert Valley and Lower Santa Ana River watersheds; the other three Urban Runoff Diversion Projects were: the Santa Ana River, Huntington Beach Pump Station, and Greenville - Banning Channel.
The purpose of the Urban Runoff Diversion Projects is to prevent untreated urban runoff from reaching the ocean waters. Urban runoff has been suspected as one of several possible sources that may contribute to high coliform bacteria counts along Huntington State Beach. The projects include the installation of pumps to divert over 95% of the non-storm runoff from the Talbert and Lower Santa Ana River watershed to the nearby OCSD wastewater treatment plant. The proposed projects divert seasonal urban runoff (containing animal waste, fertilizers, waste oils, and other chemicals that are nutrients for bacteria) into the sanitary sewer system at four different locations to reduce water pollution.
The project consisted of constructing low flow pumps to divert non-storm water urban runoff to an OCSD trunk sewer line, an inflatable rubber dam, and a pump station. This project is located within the City of Huntington Beach Huntington upstream of Yorktown Ave and downstream of the confluence with Fountain Valley Channel.
