The origin of this phrase (I am certain you know and merely detailing for others) is literally in the once-financially-viable business of collecting urine (from public houses, outdoor toilets, and even private houses) because it was a valuable source of ammonia before the invention of the (from memory, Haber-Bosch?) process for its industrial production.
