'Shiv Jal Dhara', a Water Pyramid that produces distilled water inside using solar energy while its exterior is used to harvest rainwater during the monsoon has been installed recently at Roopaji Raja Beri in Barmer's Pachpadra tehsil in Rajasthan. Launched on Mahashivratri day recently, the pyramid is only the second of its kind to come up in India. The first one is in the water-scarce Kutch, in Gujarat.
The plant has a capacity to produce 1,000 litres of safe drinking per day. The operational cost is minimal since direct sunlight is being used as the energy source. Within it The rainwater is collected separately, purified, and stored in a large ground tank with a capacity of 6 lakh litres.
This Water Pyramid was innovated by Martijn Nitzsche from the Netherlands, was patented and rewarded by the World Bank with the Development Marketplace Award-2006 for small-scale water innovations. It is a uniquely designed inflated foil structure which uses energy from the sun to evaporate brackish source water and condense it to high-quality drinking water. Other backstage supporters of this humanitarian project are Jal Bhagirathi Foundation (JCF), the Aqua-Aero Water Systems BV, The Netherlands, and Acumen Fund of the US.
