Definitions for "STORMWATER"
Consists of runoff from rain, irrigation and other urban and rural sources.
That portion of precipitation that does not naturally percolate into the ground or evaporate, but flows via overland flow, interflow, pipes, and other features of a stormwater drainage system into a defined surface water body, or a constructed infiltration facility.
Rainwater that reaches a stream or other water body as surface runoff without soaking into the ground. The water may enter the stream by direct runoff, or enter a system of channels and pipes designed to carry collected rainwater directly to a stream.
