AGSA Eligibility Determination

  1. The Antioch water system serves about 32, 000 connections within Contra Costa County. The existing service area covers 28.8 square miles serving elevations from near sea level up to about elevation 400 feet, and includes the area within the City limits and some adjacent land to the northeast and the west. The principal sources of raw water supply are the San Joaquin River and the Contra Costa Canal (Canal). Canal water, purchased from CCWD, is pumped from Rock Slough and Old River in the western Delta and from the Victoria Canal in the central Delta. The City can pump water from the Canal either into the Municipal Reservoir or directly to the water treatment plant (WTP). The WTP has a maximum capacity of about 37 million gallons per day. Treated water flows into two 1.0 million gallon clearwells before entering the distribution system. The City also has a contract to purchase treated water from CCWD that is drawn from the CCWD Multipurpose Pipeline, and adds such water directly to the City?s distribution system at the Hillcrest Booster Pumping Station.
