The U.S. Army Corps of Engineers Los Angeles District and Corps contractor CDM Constructors, Inc., of Rancho Cucamonga have reached a critical milestone in the construction of the new Fort Irwin Water Treatment Plant as it began to transition to the plants commissioning phase in September.
The Reverse Osmosis pressure vessel which contains the membranes or RO filters. This is the second stage of the purification process.
The project is the design-build of a six million gallon per day water treatment plant. 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.
