The Colorado River Municipal Water District (CRMWD) recently began producing a new municipal water source using treated wastewater effluent. Their Raw Water Production Facility (RWPF) diverts up to 2.5 MGD of effluent from the Big Spring Water Reclamation Plant and treats it to near-bottled-water quality. The RWPF provides membrane filtration, reverse osmosis and ultraviolet oxidation to achieve a water quality superior to other raw water supplies controlled by the District. The product water is blended into the District’s Spence Pipeline east of Big Spring. This is the first potable reuse facility in North America to blend reclaimed water directly in a raw water distribution pipeline.
Freese and Nichols completed the design and provided construction and startup services for this unique facility. CRMWD selected Freese and Nichols for a feasibility study to assess water supply augmentation with reclaimed wastewater. Three regional projects were evaluated, located to serve CRMWD’s member cities of Big Spring, Snyder and Odessa, as well as the City of Midland, a key customer city. Following the positive feasibility determination, Freese and Nichols was retained to provide permitting, pilot testing, design and construction phase assistance for the first facility, located in Big Spring.
The project was featured in the Texas WET Magazine’s November 2011 issue and the Water Desalination Report January 2014 issue. Freese and Nichols also presented this project at the WateReuse Symposium, the AWWA Annual Conference and Exposition, and several other venues.
