Cambridge WWTP and Sewer System - Ohio Wastewater Treatment Plant

The Cambridge WWTP and Sewer System is a municipal wastewater treatment facility located in Cambridge, Ohio, serving a population of about 19,399. Situated in Guernsey County, the plant is part of the region's essential water infrastructure, managing domestic and industrial wastewater from the community. As a U.S. facility, the plant operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which is authorized by the Clean Water Act. For a population of this size, secondary treatment is typically required to reduce organic matter and suspended solids. The plant's design and operation must comply with state and federal regulations to protect water quality. The treated effluent from the Cambridge WWTP is discharged into a local water body that flows into the Muskingum River watershed, which ultimately drains to the Ohio River and then the Mississippi River. This downstream connection highlights the plant's role in maintaining the health of regional aquatic ecosystems and ensuring safe water for communities downstream.

The Cambridge WWTP discharges into a tributary of the Muskingum River, which flows into the Ohio River and eventually the Mississippi River. This watershed supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for migratory birds. The plant's treatment processes help protect downstream water quality in this ecologically significant river system.
