Stormwater program

RaindropWhat is Stormwater?

Stormwater is water that originates during rain or snow events. Stormwater does not soak into the ground and becomes surface runoff, which either flows directly into waterways like streams, lakes, tributaries or rivers, or is channeled into storm sewers, which eventually discharge to surface waters.
Where does it go?
In Middletown, the runoff you see on the streets does not get treated at the wastewater treatment plant. Once it enters the storm sewer system by way of a catch basin or storm drain, it eventually flows into a creek or tributary leading to a creek.

Why should I care?

   Stormwater picks up and carries all the pollutants it collects along the way, such as pesticides, fertilizer, animal waste, oil, litter and more. Since it is untreated, these pollutants flow directly into our creeks or tributaries, and could create water quality problems.

   Because stormwater runoff is generated from dispersed land surfaces—pavements, yards, driveways, and roofs—efforts to control stormwater pollution must consider individual, household, and public behaviors and activities that can generate pollution from these surfaces.These common individual behaviors have the potential to generate stormwater pollution:

  • littering
  • disposing of trash and recyclables
  • disposing of pet waste
  • applying lawn chemicals
  • washing cars,
  • changing motor-oil on impervious driveways
  • household behaviors like disposing leftover paint and household chemicals

What we hope to accomplish

We hope Town of Middletown residents will join with us to improve the quality of stormwater runoff reaching our creeks and tributaries. Stopping pollution at its source is the most effective way to prevent harmful pollutants from being washed by stormwater runoff into our storm drains, and ultimately, our creeks and tributaries.
