North Texas Municipal Water District
As one of the largest projects in Texas using reclaimed water to augment a surface water supply source, the East Fork Water Reuse Project provides the North Texas Municipal Water District (NTMWD) with over 102,000 acre-feet of water per year, which is enough water to serve 500,000 people. Completed at a cost of less than 25% of developing a new reservoir, in about 20% of the time, the East Fork Water Reuse Project is a signature solution of innovation.
Plummer developed the reuse strategy alongside NTMWD. The project consists of diverting an average of 91 million gallons per day (mgd) of effluent dominated water from the East Fork of the Trinity River and polishing the water in one of the largest constructed wetlands in the country (2,000 acres). The wetland-treated water is then pumped 43.5 miles to Lavon Lake to augment the District’s surface water supply source. The East Fork Water Reuse Project includes six major components:
As the prime consultant for the design effort, Plummer designed the treatment wetland, the conveyance pump station, and approximately 31.5 miles of the 84-inch pipeline.
Plummer first began work on the constructed wetland in 2004, providing design and construction services on the first of two nursery wetlands. The initial nursery, 20 acres in size, was used to provide plant stock of selected wetland species for a 200-acre second phase nursery. The 200-acre nursery, completed in early 2006, was used to provide over 1.6 million plants for the full-scale wetland that was completed in 2009.
Plummer worked successfully with local, state, and federal regulators to obtain the necessary water rights and environmental permits:
Ongoing work with the East Fork Water Reuse Project includes annual operations support including vegetation planting/management, invasive species, nuisance wildlife, vegetation coverage evaluation, soil and water sampling and analysis, evaluation of treatment performance, and routine meetings with North Texas Municipal Water District staff as well as the John Bunker Sands Wetland Center.
The East Fork Water Reuse Project exemplifies the value of public and private entities working together to provide multiple benefits to the community. Through its partnership with the Carolyn Hunt Trust Estate and construction of the John Bunker Sands Wetland Center, the project not only provides water supply, but also offers opportunities for research, education, wildlife observation, and community gatherings. As a result, the project has been visited and embraced by the public, regulators, and legislators locally, nationally, and internationally.
Plummer is proud to be associated with this project, which received the following awards:
We design solutions to the world's greatest challenges. We're ready to take on any problems you may run into.
