GILMAN STP - Advanced Wastewater Treatment Plant in Town of Aurora, Wisconsin

GILMAN STP is a wastewater treatment facility located in the Town of Aurora, Taylor County, Wisconsin, United States. The plant serves a small population of about 1,005 residents, reflecting its role in a rural community. It operates under the regulatory framework of the U.S. Clean Water Act, which mandates that municipal wastewater treatment plants meet National Pollutant Discharge Elimination System (NPDES) permit requirements to protect water quality. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 473.18 m³/day and an actual discharge volume of 302.83 m³/day, the facility operates below its capacity, indicating room for future growth or seasonal variations. The advanced treatment level typically includes nutrient removal, which is crucial for protecting sensitive water bodies. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant's location inland, far from coastal areas, reduces direct marine impact. Its advanced treatment helps safeguard the surrounding watershed, supporting aquatic life and downstream water quality in the region's rivers and streams.

The plant discharges into local streams that flow into the Chippewa River, a tributary of the Mississippi River. This watershed supports diverse aquatic ecosystems and is important for regional biodiversity. The advanced treatment at GILMAN STP helps minimize nutrient loading, protecting downstream water bodies from eutrophication and maintaining habitat quality for fish and other aquatic organisms.
