Illicit Discharge

What is an Illicit Discharge?

Only rain belongs in storm drains. Under state and local laws, illegal discharges include:

  • Used motor oil and antifreeze

  • Paint

  • Used cooking oil and grease

muddy storm drain
  • Soapy wash water

  • Mop sink rinse water

  • Pet waste (including poop bags!)

  • Food waste and wrapping, trash, and cigarette butts

  • Muddy water from disturbed areas and construction sites

  • Concrete mixing rinse water

  • Leaves, grass clippings, and other yard waste

What’s the Problem?

Storm drains rush polluted water directly to the nearest stream or pond without any treatment. That polluted water winds up in the water we drink, fish, and swim. In addition, catch basins clogged with debris, yard waste, and trash can cause roadway flooding or can become a breeding ground for rats and roaches.

What about Construction Sites?

Have you ever seen muddy water flowing to storm drains from nearby construction areas? Construction sites are required to install and maintain control measures that prevent soil erosion.
