Problem Solution
Water and chemicals used to clean equipment, work areas, parking lots and sidewalks deliver pollutants to storm drains and, ultimately, bodies of water, endangering our health Post notices of appropriate practices, provide convenient disposal containers, and train employees to implement these pollution prevention practices.
Buildings with blocked or cracked sewer laterals, leaking pipes and faulty sprinkler systems which overflow water onto the street, contribute to polluted runoff entering the storm drains. Periodically check to make sure these systems are well maintained.
If materials used for building maintenance or improvement projects are washed down the street, such pollutants will enter the storm drain system and contaminate our waterbodies. Materials such as stucco, dry wall mud, grout and concrete add sediments and particulates to the water, which harm wildlife. Properly dispose of such materials. For more information about disposal of these materials, call the Delaware Solid Waste Authority at (800)-404-7080
