The Gulf Coast Authority has begun construction of a $25 million wastewater treatment plant in North Texas.

It is expected to take until the end of the year to build the operations site and office building on Railport Parkway in Midlothian, according to a Texas Department of Licensing and Regulation filing. California-based Brown and Caldwell is listed as the design firm.

Business & Industry Connection Magazine reported that Gulf Coast Authority (GCA) and the City of Midlothian signed an interlocal agreement in November 2021 allowing the water authority to provide industrial treatment services in the city limits.

“This project is an example of our ability to quickly collaborate with industry and local subdivisions of the state to protect the environment,” GCA general manager and CEO Liz Fazio Hale told the magazine. “Our quick ingenuity in providing services specifically designed to treat the wastewater and water reuse needs of a customer, or many customers, the planning and execution of projects and in complying with complex local, state, and federal regulations truly sets us apart from other water authorities.”

GCA was created by the Texas Legislature in 1969 to restore Galveston Bay, the agency operates wastewater treatment facilities and labs in Pasadena, Texas City, Odessa, and Friendswood. According to its website, it “has the authority to own and operate regional industrial and municipal wastewater treatment plants, water systems, and solid waste facilities” across the state.

GCA’s operating budget is nearly $200 million, and its capital budget is around $150 million. It treats water for more than 90 industries and communities.
