MSD Morris Forman STP - Louisville, Kentucky Wastewater Treatment Plant

MSD Morris Forman STP is a large municipal wastewater treatment plant located in Louisville, Kentucky, serving an estimated population of 550,000. The plant is part of the Metropolitan Sewer District (MSD) infrastructure and plays a critical role in managing wastewater for the Louisville metropolitan area. As a large agglomeration serving over 150,000 people, the plant is expected to provide at least secondary treatment under the US Clean Water Act. The facility operates under National Pollutant Discharge Elimination System (NPDES) permits issued by the Kentucky Division of Water, which set effluent limits to protect water quality. The plant discharges treated wastewater into the Ohio River, a major tributary of the Mississippi River system. The Ohio River supports diverse aquatic life and provides drinking water for millions downstream. The plant's discharge is regulated to minimize impacts on this ecologically and economically important waterway.

The plant discharges into the Ohio River, which flows southwest to join the Mississippi River near Cairo, Illinois, and eventually reaches the Gulf of Mexico. The Ohio River basin supports a variety of fish species and is an important migratory corridor for birds. The plant's effluent must meet water quality standards to protect downstream ecosystems and drinking water intakes.
