Interpretations and Explanations

A down pipe on a building may be one of many depending on the rainfall load to be transported. Down pipes are sized to ensure the risk of flooding from a known rainfall intensity is reduced, thus reducing the risk of flood damage to a building (Standards Australia 1997).
