Key Features of Indus Valley City Planning

Several distinctive features characterize the city planning of the Indus Valley Civilization, providing insights into their advanced knowledge and societal structure.

Grid System

One of the most striking aspects of Indus Valley cities is the grid system. Cities were laid out with streets intersecting at right angles, creating a network of rectangular blocks. This systematic approach facilitated efficient traffic flow and easy navigation. The main streets typically ran north-south and east-west, dividing the city into distinct sectors.

Drainage System

The drainage system of the Indus Valley Civilization is considered one of the most sophisticated of the ancient world. Each house was connected to a network of drains that emptied into larger sewers running along the main streets. These sewers were covered with bricks or stone slabs, allowing for easy maintenance and preventing the spread of disease. The system included inspection traps and settling pools to filter out solid waste, showcasing an advanced understanding of public health.

Residential Areas

Residential areas were carefully planned, with houses of varying sizes indicating a hierarchical social structure. Houses were typically made of baked bricks, a durable and uniform building material. Each house had access to water and drainage facilities, and many had multiple stories. The houses featured courtyards, which provided light and ventilation, and were oriented to minimize direct sunlight during the hottest parts of the day.

Public Buildings

Indus Valley cities included several public buildings that served important functions. The Great Bath at Mohenjo-daro is a prime example, consisting of a large rectangular pool surrounded by a colonnade. It is believed to have been used for ritual bathing or other communal activities. Granaries were also common, used for storing surplus grain to ensure food security.

Citadel

Most Indus Valley cities had a citadel, a raised area that was fortified and likely served as the administrative and religious center of the city. The citadel was typically located on the western side of the city and contained important public buildings, such as the Great Bath and granaries. The fortification walls provided protection against floods and external threats.

Standardization

A remarkable aspect of Indus Valley city planning is the standardization of weights, measures, and building materials. Bricks, for example, were produced in a standard ratio of 4:2:1, ensuring uniformity in construction. This standardization suggests a centralized system of control and coordination, as well as a sophisticated understanding of engineering principles.
