Ten Mile Creek Regional Wastewater System

The Ten Mile Creek Regional Wastewater System began service in November 1970. This advanced wastewater collection and treatment facility provides service for a 98-square-mile service area in southern Dallas and northern Ellis counties.   Contracting parties include Cedar Hill, DeSoto, Duncanville, Lancaster and Ferris. More than 125,000 citizens of these cities benefit from TRA's services.

The treatment plant for this system was developed on a 100-acre tract of land a short distance northeast of Ferris with an initial treatment capacity of 6.8 million gallons per day.  In the early 1980s, substantial growth within the system's customer cities resulted in expansion to 24.0 MGD.  The TMCRWS collection system includes 58 miles of interceptor pipelines and a lift station.
In its current configuration, the TMCRWS treatment plant operates as three separate treatment trains providing primary, secondary and advanced treatment.  The system treats wastewater to a 99-percent level of purity.

TMCRWS has long been recognized by both state and federal regulatory agencies as one of the best treatment systems in Texas.  In 2012, the TMCRWS biosolids program received the Ronald B. Seiger Biosolids Management Award from the Water Environment Association of Texas -- this award recognizes programs that have made significant accomplishments in biosolids technology and management practices. The system has also received multiple platinum, gold and silver awards from the National Association of Clean Water Agencies for compliance with the stringent parameters of its wastewater discharge permit.
