The Clarksville Wastewater Department operates and maintains the treatment facility and collection system.

Wastewater treatment serves a vital need in the protection of the society from illness and disease. The department employees’ duty to the people and environment is a very serious matter. Plant operators and collection staff are on call 24 hours a day. If you experience a wastewater backup, or other problem, please do not hesitate to call for service.

The wastewater treatment facility is an activated sludge facility with an oxidation ditch, clarifiers and UV disinfection. The treated water is discharged to Mill Creek and the remaining solids are taken to the Clark-Floyd landfill. The facility is designed to handle average flows of 5.5 million gallons per day with peak flows of 22 MGD.

The collection system consists of approximately 100 miles of sanitary sewer lines and 35 lift stations. The collection system is a vital part of the Town’s infrastructure for providing safe and efficient transportation of wastewater to the treatment facility.

The facility recently underwent a major renovation that included upgrading the treatment plant and 10 pump stations. This allows the Town to produce cleaner water and to handle higher flows. The upgrades cost $30 million dollars.
