The UM excavations conducted by Dr. G. F. Dales in 1964-65 exposed a massive mud brick platform that was used to raise a group of brick buildings several meters above the street level which was seen in the foreground.
The UM excavations conducted by Dr. G. F. Dales in 1964-65 exposed a massive mud brick platform on top of which were built numerous brick buildings separated by narrow lanes.
Many of the buildings at Mohenjo-daro had two or more stories. Water from the roof and upper storey bathrooms was carried through enclosed terracotta pipes or open chutes that emptied out onto the street, such as this one on a house in DK-G Area.
A small drain leads from the well and finely fitted brick floor of the dyer's workshop to a covered drain at the edge of the street.
Many drains from upper buildings were directed to the street through enclosed channels or terracotta pipes. The pipes were made using multiple telescoping segments that fit snugly with the next segment.
A bathing platform in UM area with blocked up doorway leading into the room. The brick floor was made with carefully fitted flat paved bricks and a smaller catchment drain along the side of the platform.
A bathing platform in SD area with brick floor made with flat paved bricks. Many bathing platforms were made with watertight floors constructed with bricks laid on their edge.
Close-up view of ground floor drain outlet from the street side, showing a brick on edge with a notch was placed across the drain hole to keep objects from flowing out with the bath water.
The ground floor drain of the bathing platform empties out into the street next to tapered chute from a roof drain or a second storey bathing area.
