CONSTRUCTION BEGINS TO EXPAND PROTECTION OF ORANGE COUNTY'S GROUNDWATER BASIN FROM SEAWATER INTRUSION

Pipeline is part of visionary project that will provide new
source of high quality water

FOUNTAIN VALLEY, Calif. – The Orange County Water District (OCWD) announced today that construction is under way on a pipeline that will help provide additional protection to Orange County’s vast groundwater basin from saltwater intrusion. The announcement coincides with National Groundwater Awareness Week March 16-22, which is designed to raise awareness about groundwater as a valuable natural resource.

The pipeline, running from Ellis Avenue and Ward Street in Fountain Valley to Adams Avenue near the Santa Ana River, is being built as part of the Groundwater Replenishment (GWR) System, an innovative project designed to deliver a new supplemental source of high quality water. The System will take highly treated sewer water from the Orange County Sanitation District, which is currently sent to the ocean, and purify it to drinking water standards or better using reverse osmosis, which is used by many bottled water companies.

The additional water will be used to expand the seawater intrusion barrier as well as provide a new source of highly quality water to improve the overall quality of the water in the groundwater basin – the primary source of water for north and central Orange County residents. The 9,000 feet of new pipeline will deliver the additional water to the barrier, once the project is completed in 2007.

“The groundwater basin is one of Orange County’s most precious resources,” said Denis Bilodeau, president of the Orange County Water District Board of Directors. “Expanding the seawater barrier is needed to help maintain this natural resource for future generations.”

OCWD has protected the underground basin from ocean intrusion for the past 25 years by purifying sewer water to drinking water standards and injecting it into the groundwater basin to keep the seawater out. The seawater barrier expansion is designed to meet future needs, and will include eight new injection wells and increase the water that is injected underground each day from 15 million gallons to 40 million gallons.

Future work on the GWR System includes demolishing the existing, smaller Water Factory 21 water purification plant in Fountain Valley; constructing a new, larger more advanced technology water purification plant; and constructing new injection wells, a pump station and a large diameter 13-mile pipeline from Fountain Valley to one of OCWD’s groundwater basin recharge lakes in Anaheim. The project will produce 72,000 acre-feet (or 22.8 billion gallons) of purified water.

The GWR System’s purification process takes highly treated sewer water through a redundant high-tech water treatment system that includes microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide. The water produced by the advanced purification system will be of near-distilled water quality.

Almost one-fourth of the cost of the $450 million water purification project has been obtained through State and Federal grants. The impact of this project on the average water bill will be less than the cost of two postage stamps per month.

Orange County Water District is a special district that was created by the California State Legislature in 1933 to maintain and manage the groundwater basin under northern and central Orange County. OCWD’s groundwater basin supplies 75% of the water needs in Anaheim, Buena Park, Costa Mesa, Cypress, Fountain Valley, Fullerton, Garden Grove, Huntington Beach, Irvine, La Palma, Los Alamitos, Newport Beach, Orange, Placentia, Santa Ana, Seal Beach, Stanton, Tustin, Villa Park, Westminster, and Yorba Linda.

Orange County Sanitation District is the third largest wastewater treatment system west of the Mississippi River, serving 2.2 million residents in northern and central Orange County.
