Parama Ram, 23, maintains the photovoltaic panels that power the desalination plant in Kotri Village, Rajasthan. The plant produces over 3000 litres of drinking water per day from the brackish groundwater reserves in the area. Parama lives above the plant and is one of its biggest advocates, personally persuading 100 of the 150 families that now collect the ‘sweet’ water to trust that the system was clean. Like many of the villagers, he would often have to drink the saline ground water before the plant was installed.
