Welcome to the Town of Groton, Connecticut

Storm Water

Managing Our Rainwater Runoff
Rainwater (or stormwater) runoff is defined as rainfall or snowmelt that flows over the ground. Paved surfaces like driveways, sidewalks and streets prevent rainwater from naturally soaking into the ground. Rainwater can pick up debris, dirt, motor oils, animal droppings, soaps, fertilizers, pesticides, and other pollutants. These pollutants then flow into a storm sewer system or directly to a lake, river, wetland, and eventually, Long Island Sound. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and providing drinking water.
