You can save water in your garden by planting less grass. Shrubs and ground cover provide year-round greenery with less water and maintenance.
Following a rain or snow event, stormwater flows through yards, down driveways, over streets, and into catch basins. Catch basins are the grates on the sides of streets and they connect to the storm drain system, which conveys the water, untreated, into our local waterways, including Boston Harbor and the Charles, Neponset, and Mystic Rivers. The storm drain system is not connected to any treatment system, including the sewer system.
As stormwater travels into the catch basins, it flushes pesticides, fertilizers, pet waste, trash and debris, automotive fluids, motor oil, and other pollutants into the storm drain system. As these pollutants enter local waterways, they can be harmful to water quality and the environment.
All Boston residents play a role in reducing and preventing stormwater pollution. Learn more about how you can help prevent stormwater pollution as residents, business owners, or construction site operators.
Dog owners can help prevent the contamination of stormwater and reduce pollution in local waterways by picking up after their pets and disposing of waste in a trash receptacle. See the Scoop the Poop page for more information.
