Mountain Creek Regional Wastewater System

Mountain Creek Regional Wastewater System began providing services to Midlothian, Venus, Mansfield, plus the southern part of Grand Prairie, in 2005.  The system is capable of serving a population of 39,000 and includes a new 3.0-million-gallon-per-day treatment plant and 23 miles of pipeline, plus one new lift station and force main and an existing 0.9 MGD wastewater plant located immediately adjacent to the new plant.  
  
The treatment plant, located in Midlothian, includes drum screens, aeration basins, aerobic digesters, final clarifiers and ultraviolet light disinfection. Treated effluent is discharged to a small, unnamed receiving stream that makes its way into Joe Pool Lake.

Construction is under way at the plant to add a third clarifier and to rehabilitate the two existing clarifiers. New cloth filtration units, as well as a solids staging area, will also be added.

MCRWS was TRA's second project to use ultraviolet disinfection, an innovative technology that benefits the environment and improves safety.

Because the population of southern Dallas and northern Ellis counties is anticipated to grow to more than 87,000 by the year 2025, additional contracting parties located within the MCRWS' service area may be added to the system in the future.

MCRWS has earned the National Association of Clean Water Agencies' Peak Performance gold and silver awards for compliance with its National Pollution Discharge Elimination System permit.
