Rain / Stormwater
In the context of Low Impact Development, RWH serves as one strategy among many for stormwater management. In urban areas, unused and non infiltrated rainwater is simply stormwater in the making.
Stormwater consists of rainwater and other water sources (such as water from hoses, industry or agriculture) that run across impervious surfaces and saturated soil into street gutters and storm drains, streams, rivers, and finally the ocean. It carries with it chemicals and toxins that are picked up along the way, becoming a source of pollution.
