The Metropolitan St. Louis Sewer District s sewer drain stenciling project was developed to address non-point source pollution. The project focuses on storm and combined sewers as they both have the potential to release pollution into area rivers and streams. MSD provides this service to help reduce the improper disposal of waste such as, motor oil, pesticides, street litter, yard debris, pet waste, etc. from area streams. This Guide and all included forms, sample letter and agreements can be printed for your use with your project.
Water pollution is a threat to all mankind.
Contrary to popular belief, it is not solely caused by large companies and industry. However, our water supply is still at risk. The Environmental Protection Agency has determined that non-point source pollution is a major cause of our nation s water quality problems. Non-point source pollution occurs as a result of uninformed people dumping toxic waste into a waterway or an oil spill from an unknown source. People performing daily tasks can also contribute to non-point source pollution.
