PASADENA, CA (May 17, 2011) – Parsons is pleased to announce that it has been selected by the Orange County Water District (OCWD) to provide construction management services for the $128 million Initial Expansion of the Groundwater Replenishment System (GWRS) in Fountain Valley, CA.
Under this contract, Parsons will provide the full spectrum of construction management services, including document control, field engineering, inspection, and startup/commissioning oversight.
“Parsons is looking forward to working with the Orange County Water District on this key project,” said Tony Leketa, Parsons Group President. “We have a long history of working with Southern California customers, including those in Orange County, providing innovative technologies and creative solutions for their projects.”
Scheduled for completion in 2014, this project will increase the treatment capacity of the GWRS by 31,000 acre-feet per year (AFY) of new water supplies, bringing the total capacity of the system to 103,000 AFY. GWRS, the largest advanced water treatment facility of its kind in the world, takes highly treated wastewater and purifies it through membrane filtration, reverse osmosis, and advanced oxidation using ultraviolet light and hydrogen peroxide. This highly purified water will be percolated into OCWD’s groundwater basin to supplement its drinking water supplies as well as to augment the seawater intrusion barrier, which prevents seawater from contaminating the groundwater. The GWRS has a secondary benefit of reducing the amount of treated wastewater discharged to the Pacific Ocean off the coast of Huntington Beach.
Leketa added, “This project is important for Parsons as it strengthens our capabilities in supporting the development of advanced water treatment projects in California and around the world.”
