Scupper

A scupper is an opening in the side walls of a vessel or an open-air structure, that allows water to drain instead of pooling within the bulwark or gunwales (of a vessel), or curbing or walls (of a building).

There are two main kinds of scuppers:

  1. Ships have scuppers at deck level, to allow for ocean or rainwater drain off.[1]
  2. Buildings with railed rooftops can construct scuppers to let rainwater drain off, instead of pooling within the railing of the roof. Scuppers can also be placed in a parapet, for the same purpose.[2]
