The Storm Drainage System is a series of catch basins, and drainage ditches that collect and channel run off from streets, driveways, sidewalks, parking lots, and vegetated land surfaces. This network of pipes and ditches flow into bodies of water such as lakes, streams, rivers and oceans.

The Town of Norwell’s storm drainage system flows into many drainage areas, such as  the North River basin, and after flowing through several communities, eventually discharges into the Atlantic Ocean.
