What is storm water?

Storm water is the flow of water that results from precipitation and occurs immediately following rainfall or as a result of snowmelt. When a precipitation event occurs, several things happen to the water.

Some of the precipitation infiltrates into the soil surface, some is taken up by plants, and some is evaporated into the atmosphere. Storm water runoff is the remainder of the precipitation that flows off land surfaces and impervious areas into storm sewers and drainage ways.
