LAMBERTON WWTP - Redwood County, Minnesota Wastewater Treatment Plant

LAMBERTON WWTP is a municipal wastewater treatment facility located in Redwood County, Minnesota, United States. It serves a small population of 817 residents, reflecting its role in a rural community. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 757.08 volume units and a current discharge volume of 507.25 volume units, the facility operates below its capacity. As a US plant, it is subject to 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 Minnesota River basin, part of the larger Mississippi River watershed. This region supports diverse aquatic life and agricultural activities, making proper wastewater treatment essential for protecting downstream ecosystems and water quality.

The plant discharges into a tributary of the Minnesota River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed is primarily agricultural, with runoff contributing nutrient loads. The plant's secondary treatment helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream waters.
