A roadway system is made of pavement, curbs, gutters, and storm drainage pipes and swales. Developed areas are often built so rainwater drains into the street. Every drop of water that touches the ground has the potential to pick up pollutants.

   
Problem Solution
Litter and debris can clog storm drains and be carried into a nearby stream, pond, or river. Storm drains are not treated by water treatment facilities (as waste water is) before flowing into our ecosystem. Street litter such as Styrofoam, plastic, cigarette butts, and paper can be prevented from blowing and washing into inlets by keeping trash bins covered and by not littering.
Improperly maintained vehicles can leak fluids such as oil, gas, and antifreeze - the #1 surface water quality problem nationwide. Regular vehicle maintenance reduces the potential for leaks.
