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.
