The Village of Johnson Creek, positioned between Milwaukee and Madison in Wisconsin, has been experiencing rapid growth, earning its reputation as the "Crossroads with A Future." However, the town faced a crucial infrastructure challenge when its wastewater treatment plant, which treated an average of 0.35 million gallons per day (MGD), reached the end of its useful life, leading to increased maintenance demands for its Rotating Biological Reactors. With the Village of Johnson Creek Water Utility (VJCWU) relying solely on ratepayer revenues, the need for a sustainable and budget-friendly solution became evident.
To address this issue, the town sought the expertise of a Wisconsin engineering firm to assess advanced nutrient removal technologies that could meet stringent effluent limits. In this case study, read about the solution they chose after evaluating various options.
