Hustisford WWTP - Secondary Wastewater Treatment in Hustisford, Wisconsin

Hustisford WWTP is a municipal wastewater treatment facility located in Hustisford, Dodge County, Wisconsin, United States. The plant serves a population of 2,156 residents and operates as a secondary treatment facility, which is the standard level required by the U.S. Clean Water Act for most municipal plants. The plant has a designed capacity of 893.35 m³/day and currently discharges an average of 757.08 m³/day of treated wastewater. As a secondary treatment plant, it uses biological processes to remove organic matter and suspended solids, meeting the effluent standards set by the U.S. Environmental Protection Agency (EPA) under the National Pollutant Discharge Elimination System (NPDES) permit program. The treated effluent is discharged into a local water body, likely a tributary of the Rock River or directly into the Rock River basin, which ultimately drains into the Mississippi River. This contributes to the overall water quality of the Mississippi River watershed, supporting aquatic life and downstream ecosystems.

The plant discharges into the Rock River basin, which flows into the Mississippi River, a major waterway that drains into the Gulf of Mexico. The Mississippi River supports diverse aquatic life and is an important migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient loads, protecting downstream water quality and minimizing the risk of eutrophication in the Gulf of Mexico's hypoxic zone.
