Warwick Lagoon Wastewater Treatment Plant, Warwick, North Dakota

Warwick Lagoon is a municipal wastewater treatment facility located in Warwick, North Dakota, serving a small population of 65 residents. The plant operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater discharges. As a small facility in a rural setting, it is subject to state-level permitting through the North Dakota Department of Environmental Quality. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. Its designed capacity is 113.56 megaliters per year, with an actual discharge volume of 37.85 megaliters, indicating ample reserve capacity. The treatment process likely involves lagoon-based systems, common in small communities in the region. The treated effluent is discharged to a local water body, contributing to the watershed of the Sheyenne River, which flows into the Red River of the North and ultimately into Lake Winnipeg. The plant plays a role in protecting downstream water quality in this ecologically sensitive basin, which supports diverse aquatic life and agricultural uses.

Warwick Lagoon discharges into a local watercourse that drains into the Sheyenne River, a tributary of the Red River of the North. The Red River flows north into Lake Winnipeg, a large lake in Manitoba, Canada. The watershed is part of the Prairie Pothole Region, an ecologically important area for migratory waterfowl and wetland biodiversity. The plant's secondary treatment helps reduce nutrient loads that could contribute to eutrophication in downstream waters.
