PERC Water is working with the Design-Build-Entity (DBE) to operate, maintain and manage the Albert Robles Center (ARC) Water Recycling and Environmental Learning facility. Throughout the design and construction phase, we reviewed equipment placement and process design to ensure reliable and efficient operation. The facility includes a 48,000 square foot process building located adjacent to the three-story Administration and Learning Center. The Administration and Learning Center includes community spaces designed to educate the public about water and the groundwater replenishment project.

The Water Replenishment District of Southern California (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 storm water capture facilities. The largest component of the WIN program is ARC [formerly known as the Groundwater Reliability Improvement Project (GRIP)]. The purpose of ARC 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.

ARC 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 (ultrafiltration, reverse osmosis, and ultraviolet light “UV” disinfection). Purified water from the plant will be conveyed to the San Gabriel Coastal Spreading Grounds for groundwater replenishment via surface spreading and injection into the local groundwater aquifer. 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 ARC facility is being built on a 5.2-acre property 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.
