Central Regional Wastewater System

CRWS_Outfall_6 - Copy (2)The Central Regional Wastewater System is a large regional wastewater system located on 495 acres adjacent to the West Fork of the Trinity River and serves approximately 1.4 million customers in Dallas, Tarrant, Ellis, Johnson and Denton counties. The award-winning treatment plant serves all or portions of 20 cities in the Dallas/Fort Worth metroplex, as well as the Dallas/Fort Worth International Airport. 

The system is an advanced secondary facility which uses both aerobic and anaerobic bacteria to remove pollutants and advanced filtration processes including sand filters and cloth media filters. The system also utilizes disinfection and a solids dewatering facility, and is currently permitted to treat 189 million gallons per day (MGD). Following dewatering, the biosolids are disposed of through a beneficial land application program. The system also consists of an extensive regional network of interceptors, pipelines, lift stations and meter stations, as well as facilities for the delivery of treated effluent for golf course irrigation and lake level management under the first major urban reuse program in Texas.
