NEWBURG STP - Advanced Wastewater Treatment in Newburg, Wisconsin

NEWBURG STP is a municipal wastewater treatment facility located in Newburg, Ozaukee County, Wisconsin. The plant serves a small community of 1,154 residents and operates under the regulatory framework of the US Clean Water Act, which governs effluent quality through National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources. The plant provides advanced treatment, which goes beyond the secondary treatment standard required for most municipal plants under the Clean Water Act. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) and additional filtration or disinfection steps. The plant has a designed capacity of 454.25 thousand cubic meters per year and discharges approximately 461.82 thousand cubic meters annually. The treated effluent from NEWBURG STP ultimately drains into Lake Michigan via local streams and rivers. Lake Michigan is one of the largest freshwater lakes in the world and supports a diverse aquatic ecosystem, including native fish species and migratory birds. The plant's advanced treatment helps protect water quality in the Lake Michigan basin, which is a critical drinking water source and recreational resource for millions of people.

NEWBURG STP discharges into the Lake Michigan watershed, one of the largest freshwater systems globally. The plant's effluent enters local tributaries that flow into Lake Michigan, which supports diverse aquatic life including lake trout, whitefish, and migratory waterfowl. The lake is also a primary drinking water source for the region, making nutrient and pollutant control essential. The plant's advanced treatment reduces the risk of eutrophication and harmful algal blooms in nearshore areas.
