County, City, State Launch (302) STOPPIT Water Pollution Hotline

New Castle County, the City of Wilmington, and the Delaware Department of Transportation have announced the launch of the (302) STOPPIT water pollution hotline for residents to report pollution going into or coming out of the storm sewer system.

When City of New Castle residents see evidence that someone has dumped chemicals or debris into the storm sewer system, here’s what they can do:

  • Visit and fill out an online form
  • Call or send a text message to (302) STOPPIT (302.786.7748) with the location and details
  • Email with the location and details

The storm drains that line streets and parking lots connect to the storm sewer system and eventually reach local streams and rivers. For this reason, it is illegal for anyone to dispose of motor oil, household chemicals, yard waste, pet waste, or any other materials in storm drains and storm sewers. The partners will investigate all tips from residents and take appropriate action, which may include containment, cleanup, and issuing citations.
