What is a Stormwater Stormwater, which can also be spelled as storm water, is a body of water that formed as a result of rainfall, snow or ice melt. Stormwater can infiltrate the soil, be stored on the land surface in ponds and puddles, evaporate, or resolved to runoff. Most runoff is conveyed directly to […]
