A hollowed-out wood water supply pipe around 500 years old put in by monks, Bristol, England.

Bristol started sewer construction around 1854, although a famous slave trader, Goldney, was one of the first to lay a sewer at Randall Road in Bristol, probably around 1780.

The Bristol City Council put in all Bristol sewers prior to the formation of Wessex Water, and was also the inventor of the energy dissipation vortex and the concept of dynamic separation in the early 1950's. The concept was adopted by new York and Chicago in the early 60's.
