Additionally areas in Australia use harvested rainwater for cooking and drinking Studies done by Stout researching the feasibility in India found that Rain water harvesting was most beneficial if used for small scale irrigation which provides income with the sales of produce and the overflow can be used for ground recharge. Many countries especially those it arid environment use rainwater harvesting as a cheap and reliable source of clean water.
