Clean Storm Water Program (MS4)

The Clean Storm Water Program (also known as Municipal Separate Storm Sewer System or MS4) is part of the Clean Water Act that is federally mandated and administered by the Indiana Department of Environmental Management. The program reaches across several city departments including parks with youth education during summer camps; street sweeping with the streets department, cleaning and repairs of the city utilities’ storm system; and plans, permitting and inspection with planning and engineering.

The program’s mission is to educate the public and promote practices that help improve the quality of rain water that runs off into our streams, reservoirs, lakes and rivers. Rain water can easily become polluted before running in to these bodies of water because of contact with pet waste, lawn fertilizers, litter, oil from leaking vehicles, and much more. The water that comes out of faucets starts out as rain water, so the goal is to keep rain water as clean as possible by educating the public about easy ways to prevent water pollution.
Here are some simple things you can do to help prevent water pollution and keep Noblesville's water bodies clean:
