Colorado River Municipal Water District

The Colorado River Municipal Water District serves an area of west Texas that has experienced a prolonged dry period extending over multiple decades. The District was authorized in 1949 by an act of the 51st Legislature of the State of Texas for the purpose of providing water to the District’s member cities of Odessa, Big Spring, and Snyder. The District also has contracts to provide specified quantities of water to a number of other cities in the region, including Midland, San Angelo, and Abilene.

The District owns and operates three major surface water supplies on the Colorado River in west Texas: Lake J.B. Thomas, the E.V. Spence Reservoir, and the O.H. Ivie Reservoir. Together, the full combined capacity of these reservoirs is 1.272 million acre-feet. Additionally, CRMWD operates four wellfields for water supply.

CRMWD began operating the first direct potable reuse system in the United States in 2013. The advanced treatment facility, or Raw Water Production Facility, uses microfiltration, reverse osmosis, and ultraviolet disinfection to purify municipal effluent from the City of Big Spring wastewater treatment plant. The purified water is then blended with conventional raw water supplies and delivered to District customers. The blended water is treated at customer water treatment plants before being distributed as drinking water. The CRMWD Raw Water Production Facility can provide up to 2 million gallons per day of additional water supply.
