The most outstanding example of conjunctive use of water (prevalent in Rajasthan's arid regions) is in the city of Jodhpur, once a fabulously rich desert fort. The Jodhpur fort is situated at the edge of a rocky plateau. The former kings had built a series of canals to collect the runoff from the plateau and channel it into several tanks built in and around the fort. For houses that came up on the incline down the plateau, numerous stepwells and wells were constructed to capture seepage from the reservoirs above. In its 500-year old history, Jodhpur has witnessed many droughts, but never a desperation for water.
