The Water Treatment Plant consists of a conventional surface water treatment facility with the ability to treat approximately 16 million gallons per day and filter 21 million gallons per day. The plant utilizes remote control feed systems for the accurate measurement and injection of required chemicals. This ensures maintenance of water quality within EPA and TCEQ limits.
Treated water discharged from the City's wastewater treatment plant travels down Beals Creek to the Colorado River where it is captured in the E V. Spence Reservoir. Spence water is then pumped uphill and delivered to member and customer cities of the Colorado River Municipal Water District. Advanced treatment technologies, including micro-filtration, reverse osmosis, and ultraviolet disinfection are used to purify the effluent water prior to it being blended with raw water from other sources. These technologies produce water that meets or exceeds all primary drinking water quality standards as well as the non-mandatory guidelines set for taste considerations. This treated water is then blended with raw lake water from other sources before being delivered to the water treatment plant of Big Spring.
