The different sources in absorbing knowledge of humanity

Sources: the book "Bresnan Chapter 1: India Before the Vedas", the video "The Unvoiced Civilization"

The text and video are similar but different at the same time. Indus: The Unvoiced Civilization talk more in detail about the street in Mohenjo-daro, how it nine meters wide, and ran from north and south. Its explain the comprehensive water and drainage system, how there was a system to drain dirty water from the second story into the gutters = below, there were wells belonging to individual households. It also states that there is a belief of over 700 such wells in the city. The waters from the bath were used to flush the waste into the gutters. In effect, Mohenjo-daro was the first city to had a flush toilet system until the Roman. But they were very vague about what the bath was for as compare to the text. 

Mohenjo-daro

The text provides very thorough details of the Indus civilization geography, while the video is some detail but it is very brief. In the video it said that there were many merchants in the Indus. The merchants used the seals to identify and secure their goods, an early example of record keeping. In the video, it talks in very details about Dholavira the first Indus city of the Indus civilization. Dholavira was also well-equipped with a sophisticated water system. The water system runs both above and underground. 

Dholavira water management system

There is evidence of a reservoir (water tank), and there is believe that there 16 reservoirs around the city. There is evidence suggesting the people of Dholavira have constructed a dam. The water was dammed up and channeled through the aqueducts into the reservoirs. Even if the water flow over the side of the dam, the system was designed so that the water would be diverted into the reservoirs. The reservoirs were constructed using the natural bedrock as their base so that there was a gradual slope. The water fills up each reservoir in turn, starting with the highest reservoirs and ascending to those on the lower levels. This was how the people of Dholavira, despite the lack of rainfall, manage to save enough water to cultivate their crops and survive throughout the years. With all this reservoir full, Dholavira must have looked like a city floating on water.
