Water Supply

TRWD Illustration

Deliver a reliable, resilient supply of water to the public at the lowest cost and highest quality possible.

We provide raw water to more than 30 wholesale customers in 11 North Texas counties.

With more than two million people in the district’s rapidly growing service area, our mission is to ensure residents and businesses have a safe, reliable water supply that meets their needs today and for decades to come. Our primary wholesale customers include the cities of Arlington, Fort Worth and Mansfield and the Trinity River Authority.

TRWD is one of the largest water suppliers in Texas, providing water to more people than the entire population of New Mexico.

Lakes & Pipelines

TRWD uses a system of lakes and pipelines to provide water to more than 30 wholesale customers here in North Texas. The district owns four lakes – Bridgeport, Cedar Creek, Eagle Mountain and Richland-Chambers – and has built more than 250 miles of pipelines that move raw water from our lakes east of Dallas back to Tarrant County. We also store water in Lakes Arlington, Benbrook and Worth for future use.

Pipeline Integrity

Making sure our infrastructure works when it’s needed is a big part of what we do. Since the 1990’s, we’ve helped pioneer the use of electro-magnetic inspections to assess the status of those pipelines. The pipeline integrity program costs about 4-5 percent what it would cost to replace the entire pipeline. And it helps us get ahead of potential failures before they happen.

IPL Increases Reliability

With a new tunnel underneath the Trinity River complete, the Integrated Pipeline reaches a milestone. Workers are now beginning to add 50-foot sections of 108-inch diameter steel pipe. Eventually, this section of pipe will carry water from Cedar Creek Reservoir into Tarrant County.

The Integrated Pipeline is a joint water supply project between Dallas Water Utilities and TRWD. The project involves building an additional 150 miles of pipeline to move water from three East Texas Reservoirs into the Metroplex. When it’s fully operational, the pipeline will have the capacity to transport 350 million gallons per day – ensuring access to reliable water supplies for decades to come.

Despite the rapid growth in North Texas, TRWD’s water demands have not grown at the same pace over the last several years. That’s because our proactive water conservation efforts and initiatives are saving 50 million gallons of water a day and 20 billion gallons of water per year. Educational outreach efforts with our customers and regional partners are also helping change behaviors and create a sustainable future in North Texas.

George W. Shannon Wetlands: Innovative Water Reuse

TRWD’s George W. Shannon Wetlands Water Reuse Project is another way the district is extending its current resources to meet a rapidly growing population. A joint effort with the Texas Parks and Wildlife Department, this 2,200-acre facility near Richland-Chambers Lake was completed in 2013, and consists of a series of sedimentation ponds and wetland cells that naturally filter water diverted from the Trinity River. In 2018, the project was recognized as a Conservation Wrangler Program.

TRWD is already working on another wetlands facility at nearby Cedar Creek Lake, which will provide an additional 28 billion gallons to the district’s supply when needed. Once both are fully operational, together they will provide TRWD with enough water supply to serve an additional one million people.

Future Water Supply Planning

TRWD has a 50-year water supply plan that takes a long-range approach to meet water supply needs in our rapidly growing service area. This plan has been in place for decades and is updated regularly. In 2013, the District also completed its Integrated Water Supply Plan, a comprehensive look at all of our future supply strategies identified at that time. That effort resulted in TRWD being able to provide valuable information to the Texas State Water Plan, which we help author as part of a local water supply planning region efforts.
