ST CLOUD WWTF - Saint Cloud, Minnesota Wastewater Treatment Plant

ST CLOUD WWTF is a municipal wastewater treatment facility located in Saint Cloud, Minnesota, serving a population of about 108,526. The plant is situated in Stearns County and plays a key role in managing wastewater for this growing community in central Minnesota. As a large agglomeration under the US Clean Water Act, the plant is expected to provide secondary treatment as a minimum standard. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Minnesota Pollution Control Agency, governs its discharge limits and monitoring requirements to protect water quality. The plant's treated effluent ultimately reaches the Mississippi River, which flows southward through Minnesota and into the Gulf of Mexico. This river system supports diverse aquatic life and is a critical water resource for communities and ecosystems downstream.

The plant discharges into the Mississippi River basin, a major waterway that drains much of central North America. The river supports a wide range of fish species, migratory birds, and other wildlife. Downstream, the Mississippi River flows into the Gulf of Mexico, where nutrient loading from upstream sources can contribute to hypoxic zones. The plant's treatment performance is therefore important for both local and downstream ecological health.
