Please help by reporting illegal and accidental dumping.

Though sometimes called a storm sewer, these drainage-ways do not go through the wastewater treatment system. Stormwater flows, untreated, to local creeks, rivers and lakes and eventually becomes our tap water.

You play a vital role in keeping our waterways clean. Washing and dumping of wastes into the storm drain is a direct threat to our lakes and streams, in addition to the wildlife dependent upon these ecosystems.

Please report any spills or discharge of pollutants into storm drains or local waterways immediately to the Stormwater Hotline, at
