Stormwater

A small boy swept into a stormwater drain kept himself afloat using strokes he'd recently learned at swim school.

Stormwater control structures often include both weirs and orifices. Weirs are designed to safely pass large flows, while orifices are used to limit smaller flows.

The U.S. Environmental Protection Agency lists stormwater as the primary cause of water pollution in the United States, and encourages local communities to develop management plans to treat run-off before it pollutes their rivers, lakes or streams.

Community groups have collected 12,000 signatures demanding that New York City permanently lower the levels of the Cannonsville, Pepacton and Neversink Reservoirs to 80 percent of capacity so that stormwater runoff can have a place to go rather than charging down the river in flash floods.

Coverage under the Minnesota Pollution Control Agency (MPCA) National Pollutant Discharge Elimination System (NPDES) Construction Stormwater General Permit is required for stormwater discharges associated with construction activities disturbing one or more acres.
