ROBINSON LAGOON Wastewater Treatment Plant, Kidder County, North Dakota

ROBINSON LAGOON is a wastewater treatment facility located in Kidder County, North Dakota, United States. It serves a small population of 37 people, reflecting its role in a rural community. The plant operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 37.85 cubic meters per day and a similar discharge volume, the facility is sized appropriately for its small service area. As a lagoon system, it likely uses natural biological processes in a series of ponds to treat wastewater. The treated effluent is discharged into local surface waters, contributing to the regional hydrology of North Dakota's prairie pothole region. This area is ecologically sensitive, supporting diverse aquatic life and migratory birds. The plant's operations are subject to state and federal regulations to protect downstream water quality.

The plant discharges into local streams and wetlands within the Missouri River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. The surrounding prairie pothole region provides critical habitat for waterfowl and other wildlife. Protecting these waters from nutrient pollution is essential for maintaining ecological balance and supporting biodiversity.
