Rainwater harvesting catches rain where it falls, to store it or recharge groundwater, instead of letting it run off.
Rooftop harvesting: roof rain runs down a pipe; the dirty first flush is let out and the rest passes through a filter.
The filter’s layers of gravel, charcoal and sand trap dust and leaves before the water is stored.
Rajasthan houses store roof water in an underground tanka in the courtyard; it stays cool and lasts the dry months.
A recharge pit lets rainwater soak through gravel into the ground, raising the water table that wells draw from.
In Meghalaya split-bamboo channels on posts carry stream water downhill and drip it at the roots of plants.
A khadin of Jaisalmer is a long earthen bund across a slope; runoff held behind it soaks the field, which is then sown.
Johads and check dams in Rajasthan hold monsoon runoff so that it seeps underground instead of flowing away.
Harvesting rain reduces floods and soil loss, and in Tamil Nadu it is compulsory for every house.
