The stormwater program offers a wide range of services related to the quality and quantity of stormwater. These services include public education, storm system maintenance, inspections, management, reduction of stormwater pollution caused by illegal connections and discharges, and general drainage improvements throughout the Town.

Water drains into a storm drain

What is Stormwater?

Stormwater is runoff from rain or melted snow that flows into a storm drain and then a nearby waterway, picking up pollutants along the way. Federal and state regulators mandate Water Utilities to reduce the amount of pollution reaching waterways. 

The Indiana Department of Environmental Management (IDEM) has designated the Town of Brownsburg as a municipal separate storm sewer system (MS4). The Town is required to comply with a state-issued stormwater permit (INR040002) (PDF). Brownsburg is implementing a program to prevent stormwater pollution in urban runoff and improve the water quality of local water bodies. Annual Reporting of the MS4 program (PDF) implementation measures and goals must be submitted to IDEM annually.

Ways to Prevent Stormwater Pollution

  • Don't blow grass or pile leaves on the sidewalk or street where they can blow or wash into storm drains. Aim your mower away from paved areas. Use a leaf blower or broom to move clippings into the yard, not the street.
  • Don't dump grass clipping or other yard waste in a swale, ditch, or creek. Recycle grass clippings as a natural fertilizer. Leave them on the lawn to biodegrade or compost them for rich natural fertilizer for your plants and garden.
  • Properly dispose of yard waste at the Hendricks County Solid Waste Management District's recycling center.
  • Curbside recycling is available through Ray's Trash Service and Republic Services.


The Stormwater Master Plans was adopted by the Town Council in January 2024. This plan prioritizes infrastructure updates to accommodate the expected growth in the population in the coming years.
