Crescent Constructors, an affiliate of Zachry Construction Corp., was awarded the $89 million Prairie Creek Wastewater Treatment Plant Aeration Basin Expansion project for the city of Lewisville, Texas.
The project is a major investment in wastewater infrastructure designed to support the community's continued growth and long-term service needs.
The project will increase the plant's operating capacity from 12 million gal. per day to 16 million gal. per day through aeration basin expansion, rehabilitation and system upgrades. The improvements are the first phase of a broader plan to help the facility meet future treatment demands and move toward a long-term capacity goal of 20 million gal. per day.
"Reliable wastewater infrastructure is essential to how growing communities plan for the future," said Ryan Glanz, vice president of Crescent Constructors. "We appreciate the opportunity to support the city of Lewisville as it invests in dependable service for residents, businesses and future development."
The project scope includes the removal of an older portion of the wastewater treatment plant to make room for expansion of the existing aeration basin and construction of a new blower building. The work also includes rehabilitation of the existing headworks, aeration basins and return activated sludge/waste activated sludge (RAW/WAS) building, along with related piping, electrical, controls and site improvements.
"As Lewisville continues to grow, investing in critical infrastructure is essential to maintaining the high level of service our residents and businesses depend on," said Aaron Russell, director of public works for the city of Lewisville. "The Prairie Creek Wastewater Treatment Plant expansion is a strategic investment in our community's future, increasing system capacity, enhancing reliability, and ensuring we are prepared to meet the needs of a growing city for decades to come."
The work will take place within an active wastewater treatment plant. Because the facility will remain operational during construction, Crescent's team will coordinate phased construction activities, electrical and controls integration, supplier representatives and planned shutdowns to help minimize disruption to plant operations.
Completion is scheduled for Nov. 28, 2028.
The award reflects the continued expansion of Zachry Construction's water infrastructure capabilities following Crescent's affiliation with the company in 2025. Together, the teams bring specialized water and wastewater construction experience, regional relationships and broader construction resources to support public-sector infrastructure needs across North Texas and other growing markets.
