Butier Engineering, Inc. Partners with the Orange County Water District
for Final Expansion of Groundwater Replenishment System

 FOUNTAIN VALLEY, Calif. (April 14, 2023) – Butier Engineering, Inc. (Butier) was proud to partner with Orange County Water District (OCWD) and the Orange County Sanitation District (OC San), serving as the construction manager for the final expansion of the Groundwater Replenishment System (GWRS). The facility is the world’s largest advanced water purification system of its kind and a global model for potable reuse.

“This is an amazing project that will greatly benefit the residents of Orange County,” said OCWD President Cathy Green. “The $284 million GWRS Final Expansion project has increased the existing treatment capacity from 100 to 130 million gallons per day (MGD), providing enough water for 1 million people in north and central Orange County.”

This GWRS advanced water treatment system is essential to the Orange County groundwater basin because it purifies wastewater to produce high-quality water suitable for groundwater recharge. It also aids in water conservation, works to make Orange County more drought resilient, protects our environment by reducing treated wastewater discharged into the ocean, and is a strong economic benefit by lessoning the reliance on expensive imported water.

“The synergy among the project delivery team of OCWD, OC San, Shimmick Construction (Contractor), Black & Veatch (Designer), and Butier/Carollo Engineers (Construction Manager) was one of the best in our 47-year history,” said Mark Butier, President/CFO of Butier Engineering. “This highly integrated team produced excellent results, and Orange County residents will be provided a permanent, dependable water production facility as a consequence.”
