The washroom

The washrooms in the homes of Mohenjo-Daro were typically small. The brick pavement floor was sloped toward a corner where the drain was situated. The room contained a simple latrine and a washing area.

Homes with a washroom on the upper floors were fitted with vertical terracotta pipes that carried effluent down to the street-level. Wastewater flowed down into the drain ditches that ran along every avenue in the city, then into underground tunnels that carried waste away from the city.
