When pet waste is left on sidewalks, streets, yards, or other outdoor surfaces, rainwater and irrigation runoff can wash it into nearby storm drains.
Once it enters the storm drainage system, the waste is carried directly to local washes, rivers, lakes, and other waterways without treatment. Even small amounts of pet waste can contribute harmful bacteria, excess nutrients, and other pollutants to the environment, making proper cleanup an important part of protecting storm water quality.
