Central Regional Wastewater System

TRA's Central Regional Wastewater System began operations in December of 1959 as the first regional facility of its kind, serving Irving, Grand Prairie and Farmers Branch, plus a portion of western Dallas.  The system has since expanded to serve all or part of 21 contracting parties and approximately 1.2 million people in the Dallas/Fort Worth area.

CRWS includes a treatment plant, located in west Dallas, and more than 200 miles of collection system pipeline.  This regional treatment facility is one of the largest and best- operated plants in Texas - the system's staff works with state-of-the-art technology throughout the treatment process to produce clean, clear effluent that improves water quality in the Trinity River.

CRWS is capable of providing complete treatment for monthly average flows of 123.4 million gallons per day and removes 99 percent of conventional pollutants from raw wastewater.  The treatment system can handle daily maximum flows of 162 MGD treatment capacity and a two-hour peak flow maximum of 405 MGD.  CRWS also has the mechanical dewatering capability of processing 232 dry tons of sludge daily.

CRWS has a comprehensive emergency response plan to protect employees and the general public.  The plan designates four highly trained response teams of eight members each who can respond to a number of potential emergency situations.  These response teams are equipped with a mobile safety unit and state-of-the-art emergency equipment for responding to on-site emergencies.  The response teams are trained in a wide range of rescue techniques, including confined space procedures.
