Corps begins work at FTI WTP project site

FORT IRWIN, Calif.--The U.S. Army Corps of Engineers and the National Training Center at Fort Irwin began work on a $100 million water treatment plant for Fort Irwin and National Training Center Dec. 05.


The facility is a design-build effort by CDM Smith Construction to provide six million gallons of water per day to the inhabitants of the NTC.


50,000 soldiers train at the NTC annually and 85 percent of the post's permanently assigned community live on the post, which adds up to a very significant amount of water consumed and utilized for day-to-day operations.


The population of on-post inhabitants is anticipated to increase to 95 percent, but construction of the final phase of the post family housing can’t be done until the water treatment plant is completed to provide water to the additional housing.


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


The new plant will use a three-stage, electro-dialysis reversal (EDR) water treatment plant that treats all contaminants found in Fort Irwin's ground water in accordance with federal and state requirements. The plant will include: an electro-dialysis reversal (EDR) primary treatment, lime softening clarifiers, lime solids thickeners, lime sludge lagoons, reverse osmosis (RO) filters, brine treatment facility, concentrate equalization basins and a mechanical evaporator tower and feed tank, and three evaporation ponds to achieve the post’s 99 percent water recovery rate.


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