A storm drain is a network of underground pipes designed to control flooding by transporting stormwater from urban areas to a body of water. A storm drain may also be known as a curb, gutter, channel, ditch, pipe, or culvert. Facility storm drainage is therefore a network of pipes inside the envelope of a building which may include underground piping designed to control flooding by delivering stormwater from the roof to the network of pipes outside the building. Facility storm drainage is therefore restricted to that which is installed within the envelope of the structure to drain storm water from the roof of the structure.
