All operations at the District’s treatment facilities are regulated by the Texas Commission on Environmental Quality (TCEQ) and the Environmental Protection Agency (EPA). Our water meets or exceeds all of the requirements of these agencies and is rated superior by the State of Texas.
Both of the District No. 17 water treatment plants use state-of-the-art membrane microfiltration technology which is capable of filtering out particles as small as 0.1 micron in size.
The Eck Water Treatment Facility is located on Lake Travis, inside the Arkansas Bend of the Colorado River, providing the municipal drinking water supply for over 30,000 people within the District boundaries and surrounding areas. Originally built in 1961, the Eck Water Treatment Facility has been in continuous operation for over 55 years and has undergone several expansions to keep up with the District’s rapid growth and water demand. The Eck Water Treatment Facility consists of two 8 million gallon per day water treatment plants, which were last expanded in 2009.
In 2016, the District completed the Mansfield Water Treatment Facility, which includes a water treatment plant, pumping station, and two potable water storage tanks. Located just north of Mansfield Dam on Lake Travis, the plant originally had a capacity to treat 6 million gallons per day (MGD) of municipal drinking water. With the recent expansion, the facility now has a capacity of 12 MGD. The design of the Mansfield Water Treatment Plant significantly enhances the District’s resiliency, allowing it to draw water from the lake even at very low levels, down to 555 feet mean sea level. This ensures the District can reliably provide potable water during drought conditions for years to come.
