Cities of Indus Valley Civilization
The Indus Valley Civilization was an urban Civilization. It contained more than 1,000 cities and settlements. These cities contained well-organized wastewater drainage systems, trash collection systems, and possibly even public granaries and baths. Town planning is the most important characteristics of this civilisation. There were large walls and citadels but there is no evidence of monuments, palaces, or temples. The uniformity of Harappan artifacts suggests some form of authority and governance to regulate seals, weights, and bricks.
There were well-ordered wastewater drainage and trash collection systems, and possibly even public granaries and baths. Most city-dwellers were artisans and merchants grouped together in distinct neighborhoods. The quality of urban planning suggests efficient municipal governments that placed a high priority on hygiene or religious ritual. Houses opened only to inner courtyards and smaller lanes, and even the smallest homes on the city outskirts were believed to have been connected to the system, further supporting the conclusion that cleanliness was a matter of great importance.
