COLERIDGE WWTP is a municipal wastewater treatment facility located in Precinct 13, Cedar County, Nebraska, within the United States. The plant serves a small population of 673 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant's designed capacity is 151.42 volume units, matching its current discharge volume, indicating it operates at full capacity. Under the US Clean Water Act, such facilities are required to obtain National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. For small plants like this, secondary treatment is the standard requirement. The treated effluent is discharged into a local water body, likely a stream or river within the Missouri River basin, which ultimately drains to the Mississippi River and the Gulf of Mexico. The plant's operations help protect downstream aquatic ecosystems and maintain water quality in the region's surface waters.

The plant discharges into a local watercourse within the Missouri River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. This region supports diverse aquatic life and is part of an important migratory corridor for birds. The secondary treatment process reduces nutrient and pollutant loads, helping to prevent eutrophication in downstream waters.
