Jamestown SD 2 STP - Advanced Wastewater Treatment in Town of Jamestown, Wisconsin

Jamestown SD 2 STP is a municipal wastewater treatment facility located in the Town of Jamestown, Grant County, Wisconsin. The plant serves a small population of 152 residents, reflecting its role in a rural community. It operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 56.78 cubic meters per day and an actual discharge volume of 37.85 cubic meters per day, the facility operates below its capacity, indicating room for future growth or seasonal variations. The advanced treatment level suggests the plant may incorporate nutrient removal or other tertiary processes. The treated effluent is discharged into a local water body, likely a tributary of the Mississippi River basin, given the plant's location in southwestern Wisconsin. The plant's operations help protect downstream water quality in the Grant River or similar streams, which eventually drain to the Mississippi River. This contributes to the ecological health of the region's aquatic habitats.

The plant discharges into a local stream within the Mississippi River basin, ultimately draining into the Mississippi River and the Gulf of Mexico. The receiving water body supports diverse aquatic life and is part of a larger watershed that includes agricultural and natural areas. The advanced treatment helps minimize nutrient loading, which is critical for preventing eutrophication in downstream waters.
