A sophisticated and technologically advanced urban culture is evident in the Indus Valley Civilization. The quality of municipal town planning suggests knowledge of urban planning and efficient municipal governments which placed a high priority on hygiene. The streets of major cities such as Mohenjo-daro or Harappa were laid out in perfect grid patterns. The houses were protected from noise, odors, and thieves.

As seen in Harappa, Mohenjo-daro and the recently discovered Rakhigarhi, this urban plan included the world's first urban sanitation systems.

The house-building in some villages in the region still resembles in some respects the house-building of the Harappans.[26] The ancient Indus systems of sewerage and drainage that were developed and used in cities throughout the Indus Empire, were far more advanced than any found in contemporary urban sites in the Middle East and even more efficient than those in some areas of Pakistan and India today. The advanced architecture of the Harappans is shown by their impressive dockyards, granaries, warehouses, brick platforms and protective walls.
