Jefferson Co Maplewood Subdivision WWTP - Pekin, Ohio Advanced Wastewater Treatment

Jefferson Co Maplewood Subdivision WWTP is a municipal wastewater treatment facility located in Pekin, Jefferson County, Ohio, United States. The plant serves a small population of 149 residents, reflecting its role in a rural or suburban subdivision setting. The facility employs advanced treatment processes, which go beyond standard secondary treatment to remove nutrients and other pollutants. With a designed capacity of 113.56 megaliters and an annual discharge volume of 75.71 megaliters, the plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. Such permits set effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Ohio River basin. The Ohio River flows into the Mississippi River and then to the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the overall health of the watershed.

The plant discharges into a tributary of the Ohio River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Ohio River basin supports diverse aquatic life and is an important migratory corridor for fish. Advanced treatment at this plant helps reduce nutrient loading, which can cause eutrophication in downstream waters.
