California water purification facility marks major milestone

Facility to produce 15,000 acre-feet per year of purified water for injection into Southern California’s largest groundwater storage basin

The Chino Basin Program (CBP), a program led by the Inland Empire Utilities Agency (IEUA) and partners, has reached a significant milestone as environmental engineering firm Brown and Caldwell completes the preliminary design of a new 13.4 million gallons per day Advanced Water Purification Facility (AWPF), a vital component of the innovative water program.

The preliminary design, developed in partnership with Water Systems Consulting, Inc., provides the technical feasibility, planning-level design, and preliminary costs for the AWPF that can produce 15,000 acre-feet per year of purified water (water for approx. 100,000 people) for groundwater replenishment that meets Chino Basin water quality objectives and integrates the flexibility to meet potential future regulations.
