Document Description
The proposed project includes pumping of water from Coso Hay Ranch in Rose Valley to provide water to the geothermal field in the China Lake Naval Air Weapons Center. Water will be withdrawn from two existing wells at the Coso Hay Ranch property at an average rate of 3,000 gallons per minute (gpm), or approximately 4,800 acre-feet per year. The water will be transferred via a new 9 mile long pipeline. Other new infrastructure will include two water storage tanks and a lift station. Power for the proposed project is proposed to be supplied by a new 3 megawatt (MW) substation to be constructed by Southern California Edison (SCE) adjacent to the pumping equipment on the Hay Ranch property.
