History - The City of Groesbeck’s original wastewater treatment plant was built somewhere around 1950.  It consisted of an old trickling filter made from rock and clay tiles and a lagoon system which provided the minimum amount of treatment to the wastewater.  As stricter regulations were passed down from the EPA, the City completely re-designed and built a new plant in 1980 for about 1 million dollars.  The plant was designed to treat 285,000 gallons of raw wastewater per day.

Today – Since 1980 the treatment plant has undergone many up-grades and additions due to increased population and regulations passed down from EPA.  The City currently operates this modified version of the 1980 plant.  The plant is well-equipped to handle all flows of raw wastewater coming into the plant for treatment.  The current plant is permitted to treat 709,000 gallons of raw wastewater per day.

The treatment and collection system is operated by 6 state licensed operators through the Texas Commission on Environmental Quality.  The system operates 365 days a year.
