The City of Lamesa hired Parkhill, Smith and Cooper to design a new wastewater treatment plant to treat 2 million gallons per day (MGD) of raw wastewater. The new wastewater treatment plant was an activated sludge carrousel facility capable of treating to stream discharge standards.

Major components of the project included a new headworks facility, aeration basin, secondary clarifiers, UV disinfection system and a sludge dewatering belt press. In addition, PSC designed a new administration building for plant staff that included a laboratory for taking samples, UV disinfection and sludge dewatering as well as a maintenance bay for servicing of plant vehicles.  The design of the plant fits on 3 acres of land.
