Storm Water

Welcome to South Charleston’s storm water information site. We hope to educate our residents and business on how they can prevent storm water pollution.  Pollutants can enter our storm drains two ways, Direct and Indirect.

Direct entry means that the discharge is directly connected to the storm drain pipe through a sewage pipe, shop drain or other kinds of pipe. Direct entry usually produces discharges that are continuous or intermittent.sept 18 2014 playing with new camera 026

Indirect entry means that flows generated outside the storm drain inlets or by infiltrating through the joints of the pipe generally, indirect modes of entry produce intermittent or transitory discharges.


What is storm water??? Storm water is runoff is generated when precipitation from rain flows over land and does not percolate into the ground. As the runoff flows over the land or other surfaces (paved streets, parking lots building rooftops), it accumulates debris, chemicals, sediments or other pollutants that could adversely affect water quality if the runoff is discharged untreated. The primary method to control stormwater discharges is the use of best management practices. Most storm water discharges are considered point sources and require coverage under an NPDES permit.

The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from three potential sources: municipal separate storm sewer systems, construction activities, and industrial activities. Most stormwater discharges are considered point sources, and operators of sept 20, 2014 010these sources may be required to receive an NPDES permit before they can discharge. This permitting mechanism is designed to prevent stormwater runoff from washing harmful pollutants into local surface waters such as streams, rivers, lakes or coastal waters.
