Norfolk's comprehensive program addresses the quality (pollution reduction) and quantity (flood control) of our storm water runoff, while meeting state and federal environmental regulations. Norfolk's storm water system consists of 349 miles of pipes, 137 miles of ditches (33 tidal), 13 storm water ponds, 10 storm water pump stations, and 1100 outfalls discharging to waterways.

Water is essential for life. It is our most precious natural resource. Surface waters - such as rivers, lakes and the Chesapeake Bay - can easily become polluted. Both point and nonpoint sources contribute to water pollution. Storm water runoff comes from many diffuse (or nonpoint) sources.

The U.S. Environmental Protection Agency estimates that at least 50 percent of our nation's water pollution is caused by storm water runoff.
