Cedar Rapids WWTP is a municipal wastewater treatment facility located on 1st Street in Petersburg, Boone County, Nebraska. The plant serves a small population of 485 residents, reflecting the rural character of the area. It operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 151.42 megaliters, and the annual discharge volume is 227.13 megaliters, indicating that the plant handles flows above its nominal capacity. This level of treatment is typical for facilities protecting sensitive water bodies. The treated effluent is discharged into local waterways that drain into the Loup River system, eventually reaching the Platte River and the Missouri River. The plant's advanced treatment helps protect downstream aquatic habitats and supports water quality in the Platte River basin, an important migratory corridor for birds and other wildlife.

The plant discharges into tributaries of the Loup River, which flows into the Platte River and ultimately the Missouri River. The Platte River basin supports diverse aquatic life and is a critical stopover for migratory birds along the Central Flyway. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream ecosystems and maintaining water quality in this agriculturally intensive region.
