PALMYRA WWTP - Secondary Treatment Plant in Otoe County, Nebraska

PALMYRA WWTP is a municipal wastewater treatment facility located in Otoe County, Nebraska, United States. The plant serves a small community of 522 residents, reflecting its role in rural wastewater management. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 151.42 million gallons per year and discharges a similar volume annually. Under the U.S. Clean Water Act, facilities of this scale are typically permitted through the National Pollutant Discharge Elimination System (NPDES), administered by the Nebraska Department of Environment and Energy. The permit ensures compliance with effluent limits for biochemical oxygen demand, total suspended solids, and other parameters. The treated effluent is discharged into a local waterway, likely a tributary of the Missouri River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. The plant's operation helps protect downstream water quality and supports aquatic life in the region's streams and rivers.

The plant discharges into a local watercourse within the Missouri River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The receiving waters support diverse aquatic life and are part of an important migratory corridor for birds and fish. The plant's secondary treatment reduces nutrient loading, helping to mitigate downstream eutrophication risks in the Gulf of Mexico.
