Answer:
LIST OF INVENTIONS AND DISCOVERIES OF THE INDUS VALLEY CIVILISATION:
This list of inventions and discoveries of the Indus Valley Civilisation lists the technological and civilisational achievements of the Indus Valley Civilisation, an ancient civilisation which flourished in the Bronze Age around the general region of the Indus River and Ghaggar-Hakra River in what is today Pakistan, and parts of India
Public Baths: The earliest public baths are found in the ruins in of the Indus Valley Civilisation. According to John Keay, the "Great Bath" of Mohenjo Daro in present-day Pakistan was the size of 'a modest municipal swimming pool', complete with stairs leading down to the water at each one of its ends.
Grid Plan: Rehman Dheri contains the earliest evidence of a grid-planned city in south Asia dated c. 3300 BC. By 2600 BC, Mohenjo-Daro and Harappa, and other major cities of the Indus Valley Civilisation, were built with blocks divided by a grid of straight streets, running north–south and east–west. Each block was subdivided by small lanes.
Flush Toilet: Mohenjo-Daro circa 2800 BC is cited as having some of the most advanced, with toilets built into the outer walls of homes. These toilets were Western-style, albeit in a primitive form, with vertical chutes, via which waste was disposed of into cesspits or street drains.
Drainage System: The Indus Valley Civilisation had advanced sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-Daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets.
Distillation: A terracotta distillation apparatus in the Indus Valley in West Pakistan dates from around 3000 BC.
