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.

The City of Noblesville is focused on a regional education program gathering forces with local communities to help protect the White River watershed through important stormwater issues.

For the younger citizens in the City of Noblesville.

The City of Noblesville is also focused on ensuring companies and homeowners have the education they need to manage the stormwater infrastructure. In participation with the White River Alliance the following programs are offered.


The City of Noblesville and its regional partners have developed many ways for individuals interested in assisting in helping us maintain and improve our watershed.

 Clear Choices Clear Water offers opportunities for individuals of groups to  pledge to improve issues that directly impact our water quality.

The White River Alliance offers many opportunities to get involved in the active management of the White River and its watershed. Such as:



Polluted stormwater run-off is a leading cause of impairment of many U.S. water bodies. Because of this, the system of conveyances (piping, drains, ditches, streets, etc.), designed or used for collecting or conveying stormwater in urban areas, known as a Municipal Separate Storm Sewer Systems (MS4), are considered “point sources” of pollution. Under the U.S. EPA’s Clean Water Act, all point sources of polluted stormwater runoff must be regulated under a National Pollution Discharge Elimination System (NPDES) permit. The Indiana Department of Environmental Management (IDEM) is the permitting authority for Indiana and requires municipalities to develop and implement a plan to meet the NPDES permit conditions. This is known as a Stormwater Quality Management Plan (SWQMP), and must address solutions for the following elements:

  • Public Education, Outreach, Participation, and Involvement
  • Illicit Discharge Detection and Elimination
  • Construction Site Storm Water Runoff Control
  • Post-Construction Storm Water Management
  • Municipal Operations Pollution Prevention and Good Housekeeping
