GROUNDWATER RELIABILITY IMPROVEMENT PROJECT


What is GRIP?

The WRD Board of Directors established the Water Independence Now (WIN) initiative to end the District’s reliance on imported water for groundwater replenishment. WIN is comprised of a suite of projects including expansions to existing water treatment facilities, spreading operations, and stormwater capture facilities. The largest component of the WIN program is the Groundwater Reliability Improvement Project (GRIP). The purpose of GRIP is to fully eliminate the current demand for imported water by producing 21,000 acre feet annually from local alternative sources to replenish the Central Basin.

 

GRIP will purify approximately 10,000 acre feet (3.25 billion gallons) of tertiary treated (recycled) water annually to near-distilled levels through an advanced water treatment facility. Together, with another 11,000 acre feet (3.6 billion gallons) of recycled water, WRD will deliver 21,000 acre feet of water to the San Gabriel Coastal Spreading Grounds where it will percolate into the Central Basin.

The GRIP facility is being built in the City of Pico Rivera, adjacent to the San Gabriel River, allowing for direct delivery of purified recycled water to an existing pipeline leading into the spreading grounds.
