We need your help to stop illegal dumping! 

Only clean water is allowed to flow freely into a storm drain. Wash waters, sewage, automotive fluids, construction materials, paint, trash, sediment, and food wastes are all prohibited from flowing into a storm drain. Illegal dumping is punishable by up to $10,000 and up to six months in jail. Reporting illegal dumping and discharges helps keep our local waterways pristine for all of us to enjoy. To learn more about stopping illegal dumping watch the "How to Prevent Illegal Dumping" video below produced by the Contra Costa Clean Water Program (CCCWP).
