The Wastewater Division 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.
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.
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.
- What do I do if I have a sewage odor in my home?
During dry weather, the traps in your drains or sinks can dry out allowing gases to be released into your home. This often seems to happen with basement drains. Try adding some water to all of your drains. If the odor does not go away, If it is during normal business hours, please call the Wastewater Treatment Plant at 317-852-1114 or the Utility Billing Office at 317-852-1102. You will need to actually speak to a person to ensure that your sewage issue is addressed - do not leave a message. If it is after hours, please call 911 and they will dispatch the appropriate personnel. Be prepared to provide your name, telephone number, and address.
- What items or products should not be flushed down a toilet or sink?
There are many items that should not go down your drains. Please do not put household hazardous waste, anything plastic, toys, anything metal, oils and greases, cat litter, or baby wipes down your drain. The household hazardous waste can endanger lives and upset the treatment plant processes when dumped down the drain. The other items listed can cause blockages in your sewer lateral, the sewer main, or damage pumps and motors. These items are ultimately screened out at the treatment plant and put in the trash. So please plan on recycling them or disposing of them in your trash at home. Thank you!
- What is inflow?
Inflow is the water that enters a sanitary sewer system as the result of connections that allow stormwater or snow melt to enter the sanitary sewer system. In Brownsburg, the majority of the sanitary sewers and stormwater sewers are operated separately. If someone in one of these separated areas connects their gutters or sump pumps to the sanitary sewer instead of the storm sewer, it could cause flooding and backups of the sanitary sewer system. Furthermore, it is illegal to connect stormwater into the sanitary sewer system.
- What size classification is Brownsburg's Wastewater Treatment Plant?
The Brownsburg Wastewater Treatment Plant is considered a large facility with a Class IV classification determined by the Indiana Department of Environmental Management. The current average daily design capacity is rated at 5.25 million gallons per day.
