NWWSD Risingsun WWTP and Sewer System - Advanced Treatment in Risingsun, Ohio

The NWWSD Risingsun WWTP and Sewer System is a municipal wastewater treatment facility located in Risingsun, Wood County, Ohio. It serves a small community of approximately 825 residents, providing essential sanitation services for the area. The plant is situated in a rural setting within the Great Lakes Basin. The facility employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 359.61 thousand gallons per day, it operates under the regulatory framework of the US Clean Water Act, which mandates National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. As an advanced treatment plant, it likely meets stringent effluent limits to protect water quality. The treated effluent is discharged into local streams that flow into the Portage River, which ultimately drains into Lake Erie. This watershed is ecologically significant, supporting diverse aquatic life and providing habitat for fish and migratory birds. The plant's advanced treatment helps minimize nutrient loading and other pollutants, contributing to the health of the Lake Erie ecosystem.

The plant discharges into tributaries of the Portage River, which flows northward into Lake Erie. Lake Erie is the shallowest of the Great Lakes and is particularly sensitive to nutrient pollution, which can cause harmful algal blooms. The advanced treatment at this plant helps reduce phosphorus and nitrogen inputs, protecting downstream aquatic habitats and recreational uses.
