From Wikipedia, the free encyclopedia
Johad (Hindi: जोहड) is a traditional pucca rainwater storage tank, mainly used for drinking purposes. In the arid and semi arid areas of Rajasthan, the annual rainfall is very low, of the scale of 450 to 600 mm. The ground water is as deep as 200 feet (60 m), and at places water is hard and salty. The people in the region depend on rainwater harvesting. The July and August rainwater is stored in pucca tanks and used throughout the year for drinking purposes. Bawdis and johads are traditionally constructed for storing water received from rainfall in this arid region of Rajasthan.
