Latty WWTP and Sewer System - Paulding County, Ohio Wastewater Treatment

Latty WWTP and Sewer System is a municipal wastewater treatment facility located in Paulding County, Ohio, United States. It serves a small population of approximately 200 residents, reflecting its role in a rural community. The plant is situated in the northwestern part of the state, near the Indiana border. The facility employs advanced treatment processes, ensuring a high level of effluent quality. It has a designed capacity of 90.85 megaliters and discharges an annual volume of 75.71 megaliters. As a US plant, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency, which set limits on pollutant discharges to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Maumee River basin, which flows into Lake Erie. This watershed is part of the Great Lakes system, supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment helps minimize nutrient loading, which is critical for reducing harmful algal blooms in Lake Erie.

The plant's discharge enters the Maumee River watershed, which drains into Lake Erie, the shallowest and most biologically productive of the Great Lakes. Lake Erie supports a valuable fishery and provides drinking water for over 11 million people. The region is sensitive to nutrient pollution, particularly phosphorus, which can fuel harmful algal blooms. Advanced treatment at this plant helps reduce the risk of such blooms, protecting both ecological health and human uses of the lake.
