Bloomville WWTP and Sewers - Secondary Treatment Plant in Bloomville, Ohio

Bloomville WWTP and Sewers is a municipal wastewater treatment facility located in Bloomville, Seneca County, Ohio, United States. The plant serves a small community of about 1,045 people, providing secondary treatment to manage domestic wastewater. It is situated inland, more than 10 kilometers from the coast, but within 50 kilometers of Lake Erie. The plant operates with a designed capacity of 378.54 megaliters per year and currently discharges 363.40 megaliters per year, indicating near-capacity utilization. As a secondary treatment facility, it meets the standard requirements under the U.S. Clean Water Act, which mandates secondary treatment for municipal plants. The plant is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency, ensuring compliance with effluent limits. The treated effluent from Bloomville WWTP flows into local streams that drain into the Sandusky River watershed, ultimately reaching Lake Erie. Lake Erie is a vital freshwater resource supporting diverse aquatic life and providing drinking water for millions. The plant's discharge contributes to the nutrient load in the basin, making proper treatment essential for preventing eutrophication and harmful algal blooms in the lake.

The plant discharges into tributaries of the Sandusky River, which flows north into Lake Erie, part of the Great Lakes system. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting a rich fishery and serving as a critical water source. The region is agriculturally intensive, and nutrient runoff from wastewater and farms contributes to seasonal algal blooms, making effective secondary treatment and nutrient management important for downstream water quality.
