Bob Derrington Water Reclamation Plant

The City of Odessa's Bob Derrington Water Reclamation Plant is located in Midland County.

Water Treatment

The Plant receives approximately 6.0 million gallons per day (MGD) of wastewater generated in the residences and commercial/industrial facilities in Odessa. The wastewater is treated using an activated sludge process in which biological organisms are used to clean the wastewater to a quality which meets or exceeds state and federal permit limitations. After the biological process is complete, the water is filtered and disinfected with chlorine.

The Derrington Plant is manned 24 hours a day by TCEQ licensed operators.


The Plant is operated so efficiently that in 1997, it was awarded the Pinnacle Award by the (TCEQ) Texas Commission on Environmental Quality.

Water Usage

The Derrington Plant has a very active reuse program for its high quality effluent. Up to 3 MGD is used by a local industry for cooling tower and fire protection water. In addition, up to 3 MGD is used for irrigation purposes. Irrigation customers include golf courses, Texas Department of Transportation, city parks, and one of Texas' first residential reuse projects. Reuse water is also used at Memorial Gardens to maintain a satisfactory water level in the pond.


Sludge generated at the Derrington Plant is dewatered using a belt filter press and is disposed of at a TCEQ approved landfill.
