Beach Lagoon Wastewater Treatment Plant, Beach, North Dakota

Beach Lagoon is a municipal wastewater treatment facility located in Beach, North Dakota, a small town in the western part of the state. The plant serves a population of approximately 1,019 residents, reflecting the scale of a small community. It is situated in a rural, inland area with no coastal proximity. The plant provides secondary treatment, a standard level for small communities in the United States. With a designed capacity of 946.35 cubic meters per day and a discharge volume of 378.54 cubic meters per day, it operates well within its capacity. Under the U.S. Clean Water Act, such facilities are regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent from Beach Lagoon is discharged into the local watershed, which ultimately drains into the Missouri River basin. This region supports diverse aquatic life and is part of a larger river system that flows into the Mississippi River and eventually the Gulf of Mexico. The plant plays a key role in protecting downstream water quality in this ecologically important area.
