Municipal Separate Storm Sewer System Program 

As part of the Federal Clean Water Act and the State of Indiana Administrative Code, over 200 towns, cities, and other entities in the state of Indiana are required to develop and implement a plan to address stormwater quality. Fishers is one of these communities. 

This program is called the Municipal Separate Storm Sewer System Program (MS4 Program) and it is comprised of the following six control measures required by law:

  • Public Education and Outreach 
  • Public Participation/Involvement 
  • Illicit Discharge Detection/Elimination (Illegal Dumping Enforcement) 
  • Construction Site Runoff Control (During Construction Water Quality Controls) 
  • Post-Construction Runoff Control (Long Term Site Water Quality Controls) 
  • Municipal Pollution Prevention/Good Housekeeping (City Facility Water Quality Control

Pollution Control

Stormwater quality is important to everyone. Rainwater that falls on streets, parking lots, rooftops, and lawns often becomes polluted by automotive fluids, detergents and chemicals, eroded soils, and lawn fertilizers before it enters the Fishers storm sewer system through inlets. This polluted stormwater runoff travels through the storm sewers directly into ponds, streams, and rivers without receiving treatment. 

This affects our ability to use the water for swimming, drinking, fishing, and also degrades the aquatic life habitat. Fishers is working to reduce the pollutants entering area waterways.
