Don't Let the Wrong Things Go Down Our Storm Drains
Illicit Discharges and Illegal Dumping in the Storm Drains
What is an illicit discharge?
An illicit discharge is generally any material, liquid or oil that enters the storm drain system AND is not composed entirely of storm water. We all need to play a role in preventing the wrong fluids, materials and runoff from washing down the storm drain since it can pollute our streams and impact our drinking water.
Potential Sources of Illicit Discharges
Used motor vehicle fluids
Household Hazardous Waste (such as household cleaners, paints, and pesticides)
Discharge from unpermitted industrial operations
Grass clippings and leaf litter
What is not considered an Illicit Discharge?
Flushing water from the fire hydrants and firefighting operations
- Landscape irrigation and lawn watering
- Air conditioning condensation and crawl space pump water that runs off property
- Dechlorinated pool water (allow pool water to sit several days before
draining your pool)
Individual residential car washing
How can you help?
As part of our efforts to protect waterways, Prince William County holds a storm water permit through the Virginia Department of Environmental Quality. This permit requires us to monitor, conduct inspections and eliminate potential pollutants. Eliminating pollution contained in storm water runoff is considered the most efficient and cost effective method of reducing pollution in natural water bodies.
There may be incidents where unwanted materials enter the storm drains, so we ask the public to help us keep an eye on these important entryways to our streams.
Public Works monitors, inspects and helps prevent materials and liquids (other than rain and storm water) from entering the storm drains.
Please advise Public Works if you see anyone flushing, dumping or pushing unwanted items such as used motor oil, hazardous waste, or grass clippings into storm drains.
The public can report problems to our office at 703-792-7070 or send an email to us at firstname.lastname@example.org.
