Standpipe → The word is formed from "stand" (from Old English "standan", meaning to stand) and "pipe" (from Old French "pippe", meaning a tube or pipe). A standpipe is a pipe that stands upright, typically used for water supply.
Think of something that 'stands' upright ('stand') and is a 'tube' ('pipe') for carrying water — that's what a standpipe is.
