Edinburg Lagoon Wastewater Treatment Plant, Edinburg, North Dakota

Edinburg Lagoon is a municipal wastewater treatment facility located in Edinburg, Walsh County, North Dakota. The plant serves a small population of 196 residents, providing secondary treatment to meet local environmental standards. As a secondary treatment plant, Edinburg Lagoon uses biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 75.71 million gallons per year, with a discharge volume matching that capacity. It operates under the regulatory framework of the US Clean Water Act, which requires NPDES permits for discharges into surface waters. The treated effluent from Edinburg Lagoon is discharged into a local water body, likely a tributary of the Red River of the North, which flows north into Lake Winnipeg and eventually into Hudson Bay. The plant plays a key role in protecting water quality in this prairie watershed, supporting downstream aquatic ecosystems.

Edinburg Lagoon discharges into a local water body within the Red River of the North basin. The Red River flows north through North Dakota and Manitoba, Canada, into Lake Winnipeg, a large freshwater lake that supports diverse fish populations and migratory birds. The plant's secondary treatment helps reduce nutrient loads that could contribute to eutrophication in downstream waters.
