The Great Bath

It is about 55 meters long and 33 meters wide.
It is found to contain a large, open space at the center.
Galleries and rooms lie on all sides. In the central space, there was the provision of a large swimming enclosure, having the measurements of 12 meters long, 7 meters wide and 24 meters deep.
There is a set of steps from all four sides that leads towards the pool.
The pool was fed with water through a well.
The water was discharged probably by a huge drain with a cor-belled roof more than 1.8 meters in height.

Streets and Drains

All the streets and lanes across neighborhoods in Mohenjo-daro had drains.
In addition there was also provision for managing wastewater inside the houses with vertical pipes in the walls that led to chutes opening on to the street, as well as drains from bathing floors that flowed towards the street drains.
The street drains were typically made of baked brick, with special shaped bricks to form corners. The bricks were closely fitted and sealed with mud mortar.

Granary

It is a brick structure that was built on a massive brick foundation over 45 meters north south and 45 meters east-west.
Two rows of six rooms that appear to be foundations are arranged along a central passageway that is about 7 meters wide and partly paved with baked bricks.
Each room measures 15.2 by 6.1 meters and has three sleeper walls with air space between them.
A wooden superstructure supported in some places by large columns would have been built on top of the brick foundations, with stairs leading up from the central passage area.
Small triangular opening may have served as air ducts to allow the flow of fresh air beneath the hollow floors

Wells

One of only eight wells, public and private, that have thus far been discovered at Harappa.
Most of the water used by the population probably came from the adjacent Ravi River
. The curved wall was probably a large drain used during the latter stages of ancient Harappa, around 2,000 B.C.E

Earliest Form of Sanitary Engineering

1st known toilets and running water in residential buildings in the world.
By 2500 BC, highly developed drainage system where wastewater from each house flowed into the main drain.
The ancient Indus systems of sewage and drainage that were developed and used in cities throughout the Indus Empire were far more advanced than any found in contemporary urban sites in the Middle East and even more efficient than those in some areas of modern Pakistan and India today
