Edgeley Lagoon Wastewater Treatment Plant - Edgeley, North Dakota

Edgeley Lagoon is a wastewater treatment facility located in Edgeley, North Dakota, serving a population of approximately 563 residents. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring that wastewater is treated to reduce organic matter and suspended solids before discharge. As a lagoon-based system, the plant relies on natural biological processes to treat wastewater. The facility has a designed capacity of 264.98 units and a discharge volume of 227.13 units, indicating it operates below its maximum capacity. Under the U.S. Clean Water Act, such plants are typically regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the state or EPA, which set effluent limits to protect water quality. The treated effluent from Edgeley Lagoon is discharged into a local water body, which eventually drains into the larger Missouri River basin. This watershed supports diverse aquatic life and is an important resource for agriculture and recreation in the region. The plant's operations help maintain the ecological health of the surrounding environment by preventing untreated wastewater from entering local streams and rivers.

Edgeley Lagoon discharges into a local watercourse that flows into the James River, a tributary of the Missouri River. The Missouri River basin is a major hydrological system in the Great Plains, supporting diverse fish species and providing habitat for migratory birds. The plant's secondary treatment helps protect downstream water quality in this agriculturally intensive region.
