Sewer pipes, which were formed from clay as early as 4000BCE by the Mesopotmians, were created to collect rainwater in wells and to drain wastewater from settlements. The earliest found examples of these are in the Temple of Bel at Nippur and at Eshnunna, and the earliest found use of latrines made from bricks was found in the city of Uruk. Clay pipes became more developed and from 3200BCE they had sections that could be detached and replaced to allow for cleaning, as seen in the Hittie city of Hattusa.
