Corps awards $100 million water treatment plant construction contract

Published Sept. 28, 2012

LOS ANGELES.--The U.S. Army Corps of Engineers Los Angeles district awarded CDM Constructors, Inc., of Rancho Cucamonga, Calif., a $100.1 million construction contract Sept. 12 for a new water treatment and distribution System project at Fort Irwin.

The facility is designed to provide up to six million gallons of water per day to the inhabitants of the National Training Center.  Fort Irwin Garrison officials estimate 50,000 soldiers train at the NTC annually and 85 percent of the permanently assigned community lives on the post. 

The three-year construction project will replace the current treatment system, as well as use new technologies to process the water to meet state and federal standards.

Lt. Col. Joseph Seybold, the WTP project manager with the U.S. Army Corps of Engineers, said Fort Irwin has established strict standards to conserve as much as possible of the area’s limited water resources. 

“The new WTP will use a combination of electro-dialysis reversal (EDR) technology, reverse osmosis, and a mechanical evaporator to purify the water to achieve the post’s 99 percent water recovery rate requirement,” said Seybold.  “EDR separates contaminants from source water through an electrochemical process."

The current system uses reverse osmosis to treat potable water at the post and is unable to meet current potable water demands.

The project also includes water system improvements, supporting utilities and infrastructure upgrades.
