Not all of the water generated when it rains or snows is able to be absorbed into the ground. What is left is called stormwater. As stormwater washes over roads, yards, roofs, and parking lots, it picks up pollutants such as motor oil, pet waste, fertilizer, and litter. The stormwater then makes its way into storm drains and the city’s storm sewer system. Unlike the sanitary sewer system, the storm sewers do not transport runoff flows to a treatment plant to remove the pollutants. The stormwater is discharged directly into creeks and streams, along with the litter and pollutants it has picked up along the way. This can lower the quality of our natural waterways and make our creeks and streams unfit for swimming and fishing and for supporting aquatic life. Source
Storm drain stenciling is a creative way to highlight where our water goes in urban environments. If you wish to lead a stenciling project, we can provide the following supplies.
