Petersburg WWTP - Secondary Wastewater Treatment in Petersburg, Nebraska

Petersburg WWTP is a municipal wastewater treatment plant located in Petersburg, Nebraska, serving a small population of 425 residents. The facility provides secondary treatment, a standard level for communities of this size in the United States. The plant has a designed capacity of 113.56 megaliters and currently discharges 151.42 megaliters of treated effluent annually. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated wastewater is discharged into local waterways that drain into the Platte River basin, ultimately contributing to the Missouri River system. The plant plays a key role in protecting downstream aquatic ecosystems by reducing organic pollutants and suspended solids before discharge.

The plant's discharge enters the Platte River basin, a critical waterway in Nebraska that supports diverse aquatic life and provides habitat for migratory birds along the Central Flyway. The Platte River flows into the Missouri River, which eventually reaches the Mississippi River and the Gulf of Mexico. The secondary treatment process helps maintain water quality in this ecologically sensitive region.
