What is Storm Water?  The water that flows over our streets and into our storm drains from rainstorms, garden hoses, sprinklers or other water sources is called STORM WATER.  This water NEVER goes to a wastewater treatment plant to be cleaned.  It flows directly into our local waterways, carrying with it pollutants such as used motor oil, antifreeze, paints, fertilizers, pet waste, water from washing our cars, and pesticides.
