Use of natural bitumen in the Great Bath.
Explanation of upper/lower towns and street layouts.
The larger Harappan cities were built according to precise plans. They had wide streets, which were often oriented to the cardinal directions (North, South, East, and West), creating a highly organized grid system.

This elaborate tank at Mohenjo-daro was expertly waterproofed and likely used for collective rituals or bathing.
Details on drains, wells, and the massive Dholavira reservoirs.
The Harappans gave immense importance to water management and public cleanliness. Homes often had separate bathing areas connected to a larger network of drains that safely took the wastewater away.

Harappan cities featured complex networks of covered street drains to maintain strict public hygiene.
Fill in the blanks regarding city structures and materials.
Most Harappan cities were divided into an upper town, where the likely lived, and a lower town for common people. For special structures like the Great Bath, builders ensured it was completely waterproof by applying a layer of natural over the bricks. Their water management was highly advanced; for example, the massive 73-metre-long water reservoir was discovered at the city of . To maintain overall cleanliness, wastewater from individual homes flowed directly into a network of covered drains that ran below the city .
