What was the sewer system Ancient India for?

The sewer system in Ancient India, particularly prominent in the Indus Valley Civilization, was designed for effective wastewater management and sanitation. It consisted of well-planned drainage systems, with covered drains running alongside streets and connections to individual homes. This advanced infrastructure facilitated the disposal of sewage and stormwater, promoting public health and hygiene in urban areas. Such innovations reflect the civilization's understanding of sanitation and urban planning long before similar systems were developed in other parts of the world.
