Lewellen WWTP - Secondary Treatment Plant in Lewellen, Nebraska

Lewellen WWTP is a municipal wastewater treatment plant located in Lewellen, Nebraska, a small community in Garden County. The facility serves a population of 407 and treats an annual wastewater volume of 113.56 million gallons, with a designed capacity matching that volume. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal facilities. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale are typically permitted by the Nebraska Department of Environment and Energy to ensure compliance with water quality standards. The treated effluent is discharged into a local water body that ultimately drains into the North Platte River, a tributary of the Platte River system. This river network supports diverse aquatic life and is an important migratory corridor for birds in the Central Flyway. The plant's operations help protect downstream water quality in the Platte River basin.

Lewellen WWTP discharges into a local water body that flows into the North Platte River, part of the Platte River watershed.
