NWWSD Custar WWTP and Sewers - Wood County, Ohio Wastewater Treatment

NWWSD Custar WWTP and Sewers is a municipal wastewater treatment facility located in Wood County, Ohio, serving a small population of 436 residents. The plant provides secondary treatment, a standard level for communities of this size in the United States, ensuring compliance with federal and state water quality standards. The plant has a designed capacity of 189.27 megaliters and treats an annual discharge volume of 151.42 megaliters. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids. The plant operates under the U.S. The treated effluent is discharged into a local water body within the Maumee River watershed, which drains into Lake Erie. This region is part of the Great Lakes Basin, a critical freshwater ecosystem. The plant's operations help protect downstream water quality and support the ecological health of the Maumee River and Lake Erie.

The plant discharges into a tributary of the Maumee River, which flows into Lake Erie, the shallowest and most biologically productive of the Great Lakes. The Maumee River watershed is predominantly agricultural, contributing nutrient runoff that can lead to harmful algal blooms in Lake Erie. The plant's secondary treatment reduces organic pollutants and helps mitigate local eutrophication risks.
