Grove City WWTS - Advanced Wastewater Treatment in Minnesota

Grove City WWTS is an advanced wastewater treatment facility located in Grove City, Minnesota, serving a population of approximately 635 residents. The plant is situated in Meeker County and operates as part of the municipal infrastructure for the small community. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. It has a designed capacity of 272.55 million gallons per year and currently discharges 230.91 million gallons annually. Under the US Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Minnesota Pollution Control Agency, ensuring compliance with water quality standards. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant plays a vital role in protecting downstream water quality and aquatic ecosystems in the region.

The plant discharges into the Mississippi River basin, which flows south to the Gulf of Mexico. The watershed supports diverse aquatic life and is an important migratory corridor for birds. Advanced treatment helps reduce nutrient loading, mitigating downstream eutrophication risks in the Gulf of Mexico hypoxic zone.
