Wells had been dug in the cities of the Indus – Sarasvati Valley by the third millennium B.

C., while the “Great Bath” was probably a water storage tank.

In the hills and mountainous regions where there are plenty of streams, simple engineering structures were used to divert the water into channels that fed the fields.

The structures became more sophisticated and much bigger when the streams turned to rivers. In the arid and semi-arid regions, where the streams are more seasonal, the diversion channels first led the water to a storage structure like a tank for later use.

Throughout India, several ingenious ways have been devised to catch and store rainwater for future use.

They are known as traditional water harvesting systems.

It is the traditional water harvesting systems that have made life possible even in the Thar Desert.

Despite being crisscrossed by a complex network of rivers, vast stretches of India have neither river nor lake to depend on.

In Himachal Pradesh a temporary headwall of boulders called kuhl was constructed across a ravine to divert the waters of natural flowing streams (khud) through a canal to the fields.

About 20 ha could be irrigated by a community kuhl.

Storage systems to collect just runoff from the watershed were also built. In the flood plains, several unique systems to control and harness the floodwaters were devised. In regions with good groundwater aquifers, dugwells with innovative methods to lift the water were in use.

Deep wells were dug in the beds of tanks and rivers, both to serve as a source of good water when the water recedes and also to recharge the groundwater when they are fully submerged.

A tank excavated at Sringaverapura near Allahabad, Uttar Pradesh, dates back to the 1st century B. Rama began his 14 year exile from here and could well have drunk water from this tank.
