Stormwater Management

Wilton Stormwater Program

Wilton riverscapeThe purpose of the EPA’s Municipal Separate Storm Sewer System (MS4) Program is to mitigate the effects of storm water pollution.

Rainwater that falls on paved streets, lawns, parking lots, and sidewalks becomes polluted stormwater. The more impervious the surface, the more stormwater runoff and impact to receiving water bodies. Typical pollutants in stormwater are trash, oil, fertilizers, sediment, sand, and bacteria. In fact, 40% of known pollution to the nation’s waters is caused by stormwater.

Here is a map of the impacted waterways in Wilton.

Wilton must comply with the requirements of MS4, and we have submitted a Notice of Intent (NOI) to comply. We must submit a written Storm Water Management Program by July 1, 2019.
