Stormwater runoff drains directly into catch basins on your street; unlike wastewater, the runoff is not treated before it empties into a local water body. That's why it's so important that our stormwater runoff remains clean. While the sanitary sewer runs to a treatment plant, the separate storm water sewer runs to Unquity and Pine Tree Brooks and the Neponset River.
Pollution of these waterways has a number of consequences. Bacterial pollution from pet waste and other sources can make waters unsafe for recreation and cause disturbances in aquatic ecosystems. Excess phosphorus or nitrogen can cause harmful algal blooms that threaten the health of aquatic systems, especially for fisheries. That's why the little things everyone can do - such as picking up pet waste, or using less lawn fertilizer - can help us keep waterways clean for everyone who uses them.
