The North Texas Municipal Water District announced May 3 that it plans to renovate its Wilson Creek Regional Wastewater Treatment Plant to serve the region's growing population while also maintaining its environmental compliance.

The North Texas Municipal Water District provides wastewater services to 1.4 million North Texas residents through its 13 member cities, which include Plano, McKinney, Frisco and Richardson.

The Wilson Creek plant, which is located at 3020 Orr Road in Allen, is the largest plant in the regional system and the backbone of the district’s treatment capabilities, according to a news release. The Wilson Creek improvement project includes replacing current mechanisms, increasing the flow for ultraviolet disinfection and adding a new aeration control building to the plant.

According to the release, the completed upgrades and the replacement of aging equipment will improve plant reliability, optimize process performance and energy efficiency, and increase flexibility at the plant. In addition, the improvements are designed to help the plant meet current wastewater regulatory permit requirements.

The detailed design and engineering of the upgrades is being led by consultant Brown and Caldwell.


“We applaud the district for taking proactive steps to ensure its customers continue to receive exemplary levels of service,” said Adam Evans, Brown and Caldwell principal in charge, in a statement. “Our highly qualified team is honored to bring proven and new technologies to transform the facility in alignment with the district’s long-term goals.”

The design phase of the project is expected to be completed by November 2023 with construction scheduled to last until March 2026, according to the release.

According to the release, the district’s wastewater system consists of more than 226 miles of large-diameter pipelines, 23 lift stations, and 13 wastewater treatment plants that convey and treat approximately 163 million gallons of wastewater per day.
