The Water Utilities Department has responsibility for operating, maintaining and improving an extensive system of pipes, lift stations, and treatment processes all aimed at providing safe and reliable removal of sanitary waste from buildings and homes and ensuring that streets and parking areas do not flood with stormwater.

Wastewater Treatment Plant

What Comprises the Wastewater System?

Brownsburg has a 5.25 million gallon per day Class IV facility and 35 lift stations for treating the raw sewage produced by residents and businesses. The plant is regulated by the Indiana Department of Environmental Management (IDEM) and the Environmental Protection Agency (EPA) through a National Pollutant Discharge Elimination System Permit. The treatment plant uses biological processes that remove and reduce the pollutant concentrations to meet the requirements included in an National Pollutant Discharge Elimination System (NPDES) permit. This permit contains the approval criteria allowing us to discharge treated water into White Lick Creek.

Sewer Rates

We are committed to operating efficiently and keeping sewer rates affordable for our customers. For information on rates, visit our Utility Rates page.


The Wastewater Treatment Plant and Sanitary Sewer Master Plans were adopted by the Town Council in January 2024. These plans prioritize infrastructure updates to accommodate the expected growth in the population in the coming years.

These plans are living documents to help determine future priorities and highlight where expansions, such as additional treatment plants and water towers, could occur in compliance with the Indiana Department of Environmental Management.
