Dorchester WWTP - Secondary Wastewater Treatment in Saline County, Nebraska

Dorchester WWTP is a municipal wastewater treatment facility located in Saline County, Nebraska, United States. The plant serves a small population of 615 residents, providing secondary treatment to meet state and federal water quality standards. The plant has a designed capacity of 227.12 megaliters and treats an annual discharge volume of 189.27 megaliters. As a secondary treatment facility, it operates under the U.S. Clean Water Act, which requires such plants to meet effluent limits set by the National Pollutant Discharge Elimination System (NPDES) permits, typically administered by the Nebraska Department of Environment and Energy. The treated effluent is discharged into local waterways that drain into the Big Blue River basin, eventually reaching the Platte River and the Missouri River system. This watershed supports diverse aquatic life and provides water for agricultural and recreational uses downstream.

The plant's discharge enters the Big Blue River watershed, which flows into the Platte River and ultimately the Missouri River. This river system supports a variety of fish species and provides critical habitat for migratory birds along the Central Flyway. The surrounding area is primarily agricultural, so the plant's nutrient removal helps protect downstream water quality from potential eutrophication.
