BRISTOL UD 1 STP - Bristol, Wisconsin Wastewater Treatment Plant

BRISTOL UD 1 STP is a municipal wastewater treatment plant located in Bristol, Wisconsin, within Kenosha County. The facility serves a population of approximately 1,377 residents and has a designed capacity of 1.00 million gallons per day, reflecting its role as a small-scale treatment facility for the local community. As a U.S. wastewater treatment plant, BRISTOL UD 1 STP operates under the Clean Water Act, administered by the Wisconsin Department of Natural Resources (WDNR) through the National Pollutant Discharge Elimination System (NPDES) permit program. Plants of this scale typically employ secondary treatment to meet federal and state effluent standards. The plant discharges treated wastewater into local waterways that ultimately drain into the Fox River watershed and Lake Michigan. This connection to the Great Lakes system underscores the importance of effective treatment to protect water quality and aquatic ecosystems in the region.

The plant's discharge contributes to the Fox River watershed, which flows into Lake Michigan, a vital freshwater resource supporting diverse aquatic life and recreational activities. The surrounding area is part of the Great Lakes Basin, an ecologically sensitive region where nutrient management is critical to prevent algal blooms and maintain water quality. The plant's location inland, over 50 km from the coast, reduces direct marine impact but still requires careful operation to protect downstream ecosystems.
