LEBANON WWTP - Lebanon, Indiana Wastewater Treatment Plant

LEBANON WWTP is a municipal wastewater treatment facility located in Lebanon, Boone County, Indiana, serving a population of around 16,300. The plant is part of the region's infrastructure managed by local authorities, discharging treated effluent into nearby waterways that ultimately drain into the Mississippi River Basin. As a US facility, the plant operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. For a community of this size, secondary treatment is typically required, with possible nutrient removal if the receiving water body is sensitive. The Indiana Department of Environmental Management oversees compliance and permit renewals. The plant's treated effluent enters local streams that flow into the Wabash River, a major tributary of the Ohio River, which joins the Mississippi River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. Proper treatment helps protect water quality in this agriculturally and ecologically important region.

The plant discharges into local streams that are part of the Wabash River watershed, which flows into the Ohio River and ultimately the Mississippi River. This basin supports a variety of fish and wildlife, including migratory species. The region's agricultural land use means nutrient management is important to prevent algal blooms downstream.
