Water Facilities

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.



Eck Water Treatment Facility

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.

Mansfield Water Treatment Facility

In 2016, the District completed the Mansfield Water Treatment Facility.  This Facility consists of a water treatment plant, pumping station and a pair of potable water storage tanks.  The facility is  located just north of the Mansfield Dam on Lake Travis. The water plant is capable of treating 6 million gallons per day (MGD) of municipal drinking water and is currently being expanded to 12 MGD.  The design of the Mansfield Water Treatment  Plant provides the District with a significant increase in resiliency through its capability of drawing water from the lake at very low levels; down to 555 feet mean sea level. This will ensure the District’s ability to reliably provide potable water during drought conditions for years to come.
