Red Oak Creek Regional Wastewater System

TRA's Red Oak Creek Regional Wastewater System serves all of Ovilla, Glenn Heights and Red Oak, along with portions of DeSoto, Cedar Hill and Lancaster. Capable of serving a population of 60,000, the system consists of a 6-million-gallon-per-day treatment plant and 24 miles of pipeline. The ROCRWS collection system includes 12 meter stations, plus one lift station and force main. Operators monitor and control wastewater flows and processes with a state-of-the-art process control system.

ROCRWS treats water to meet one of the most stringent limits in the DFW Metroplex. The treatment plant includes drum screens, aeration basins, aerobic digesters and final clarifiers. Odor-reducing biofilters dewater biosolids, and the facility uses ultraviolet light to disinfect treated water before discharging it into the Red Oak Creek ecosystem.

ROCRWS was designed to preserve the rural ambiance of the area surrounding the plant site. The plant is sheltered from the road by trees and gently rolling berms, and it features a pastoral landscape design with low-intensity lighting, noise control features and an administration building designed to resemble a country home. Since beginning operations in February 1991, the plant has provided a positive environmental impact on the Red Oak Creek ecosystem.

The facility has earned multiple platinum, gold and silver Peak Performance Awards from the National Association of Clean Water Agencies for excellent compliance with its National Pollution Discharge Elimination System permit.
