DELANO STP - Monticello, Minnesota Wastewater Treatment Plant

DELANO STP is a municipal wastewater treatment plant located at 975 River Street East in Monticello, Minnesota, within Wright County. The facility serves a population of approximately 5,789 people, reflecting a small to medium-sized community in the Upper Midwest region of the United States. As a U.S. wastewater facility, DELANO STP operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Minnesota Pollution Control Agency (MPCA). For plants serving populations around 5,789, secondary treatment is typically required, which includes biological processes to remove organic matter and suspended solids. Regulatory standards ensure compliance with effluent limits. The plant discharges treated effluent into a local water body, likely a tributary of the Mississippi River, which flows southward through Minnesota and ultimately into the Gulf of Mexico. The facility plays a key role in protecting downstream water quality and aquatic ecosystems in the Mississippi River Basin.

DELANO STP discharges into a receiving water body within the Mississippi River Basin. The Mississippi River flows from northern Minnesota to the Gulf of Mexico, supporting diverse aquatic life and serving as a major migratory corridor for birds and fish. The plant's treatment helps reduce nutrient loading and pollutant impacts on downstream ecosystems, including the Mississippi River and its delta.
