 ‘Bhungroo,’ which uses pipes to filter and store rain water in underground reservoirs with capacities to hold as much as 40 million litres of  water in it. It is developed by a social entrepreneur and innovator based in Ahmedabad, Gujarat, Biplab Ketan Paul who has devised an innovative and path-breaking water-harvesting community initiative led by women. Facilitated more than 14,000 farmers and transformed 40,000 acres of barren, disaster-affected or highly saline land into productive farms.

A single Bhungroo - the Gujarati word for a hollow pipe –unit harvests water for only about 10 days a year, but supplies water for as long as seven months and ensures food security for five families by irrigating two crops in two seasons for at least 25 years. Besides, this non-saline rainwater reduces the salinity of groundwater, making it fit for agricultural use.

It can be promoted as a social business model that ensures women empowerment, as each Bhungroo unit has to be owned and managed by women from small and marginal farmer families

The current Bhungroo units come in 17 designs and their prices range from Rs. four to 22 lakhs, based upon 29 variables such as rainfall and subsoil. Installation of the unit takes a mere three days.
 A one-time investment of Rs. 8 to 9 lakh in Bhungroo can generate an income of Rs. 3 lakh per annum and the investor breaks even after 36 months. It increases a farmer’s agricultural income illustratively from Rs 11,000 a year to a minimum of Rs 34,000 in three months.
Each Bhungroo unit caters to the irrigation need of 15 acres of land, making that much land productive twice a year.
Bhungroo technology has been replicated widely in Gujarat, Karnataka, Bihar, Jharkhand, West Bengal and Odisha. Internationally, Bhungroo has crossed over to Africa (Ghana, Liberia, Kenya), EU countries, Bangladesh, Cambodia and Vietnam.
