Stormwater Management

 

Polluted runoff (commonly called stormwater runoff ) carries pollution and trash as it flows into our streams, lakes, ponds and rivers, making them unhealthy.

Stormwater Management is the process where we slow, soak in, or store stormwater to help reduce the amount of pollution entering our waterways.  Montgomery County uses above and below ground structures (we call them stormwater management facilities) to remove pollutants from the stormwater before the water gets to streams.
