Storm drains convey water through the public storm water system to the nearest stream or lake without treatment. It is important to keep vehicle wash water from entering storm drains because detergents, oils, and heavy metals can be toxic to aquatic life. The SudSafe™ car wash kit captures wash water before it enters the storm drain and pumps it to either a grassy area or sanitary sewer. Using this kit helps to protect the quality of water in your community.
