The main objectives of rainwater harvesting are:

In ancient India, there was a tradition of developing a rainwater harvesting system. People knew the rainfall regimes. Rooftop rainwater harvesting was practiced to store drinking water, particularly in Rajasthan. In Bikaner and Barmer regions most of the houses have underground tanks or tankas, for storing drinking water.

The tankas were built inside the house or in the courtyard. These are connected to the sloping roofs of the houses with a pipe. The first spell of rain is used for cleaning the roofs and the pipes. The rain water thus collected is considered as the purest form of water. It is an extremely reliable source of drinking water.
