Contract highlights: Wastewater treatment plant expansion project
Contract amount: Approximately $89 million
Project location: Lewisville, Texas
Owner: City of Lewisville

Texas adds another water project. Crescent Constructors—a contractor focused on municipal and wastewater projects—announced on June 30 that it has been awarded the contract for the aeration basin expansion at the Prairie Creek Wastewater Treatment Plant in Lewisville. According to Texas Bid Network, the project is valued at approximately $89 million.

According to the announcement, Crescent will increase the plant's daily treatment capacity from 12 million gallons to 16 million gallons. To achieve this, Crescent will expand the aeration basins and demolish older parts of the facility to make room for the expansion and a new blower building. The project also includes rehabilitation of existing influent facilities, aeration basins, and buildings for return activated sludge and waste activated sludge, along with associated piping, electrical, control systems, and site improvements.

The wastewater treatment plant will remain operational during construction, so Crescent will phase the work while coordinating electrical and control system integration, vendor representatives, and planned shutdowns to minimize operational disruptions. The project is expected to be fully completed by November 2028.

This contract award is another significant milestone for Plano-based Crescent since its acquisition by San Antonio's Zachry Construction in September. Zachry acquired this water infrastructure company to strengthen its competitiveness in the rapidly growing water market.

Looking further ahead, this expansion is the first step in Lewisville's master plan to meet future water demand. According to a city press release, the plant's long-term goal is to increase daily treatment capacity to 20 million gallons. Lewisville's population is estimated at approximately 139,000, and according to the U.S. Census Bureau, it has grown 10.6% since April 2020.
