WORLD HISTORY

Detailed explanation-1: -Tunnels under Mohenjo-Daro carried the city’s waste to a nearby estuary. Almost all of the city’s houses had indoor baths and latrines with drains, and the city also showed its dedication to cleanliness with a large public bathhouse used for ritual bathing.

Detailed explanation-2: -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. Gregory Possehl observes that over time, the same drains were reused by raising the walls with more bricks.

Detailed explanation-3: -Harappans demonstrated advanced architecture with dockyards, granaries, warehouses, brick platforms, and protective walls. These massive walls likely protected the Harappans from floods and may have deterred military conflicts.

Detailed explanation-4: -One of the more significant features of Harappan cities was their sophisticated water supply and waste extraction systems. In Mohenjo-daro, water was supplied from some 700 wells to both public and private facilities.

Detailed explanation-5: -The cities of Harappa and Mohenjo-daro are believed to be the first in the world to clean the city using drainage and sewer systems. Families were able to get fresh water from wells all around the city and store it in their homes.
