51-year-old Sanjay Athavale is an old member of the Green Hills group in Pune that plants trees at the four hills in the city. “I have been with this group for more than eight years now. One day we wanted to pump water up the hill and that initiative put me in touch with Chandrakant Pathak who made this bicycle project. Although the pilot didn’t work because of maintenance issues, I really liked the idea and with help from a friend (Joshi) I set it up in my house,” he said.
Joshi (who is no more) undertook water purification projects for industries and helped Athavale with the designing. Water is collected from the showers in a separate tank that has three layers of filters. Coconut peels procured from the coconut trees in his garden and stones make the first layer, then comes the sand and the last layer is made up of ecofert, a fertilizer given to Athavale by an NGO. Kardal trees have been planted inside the tank as its roots also purify the water. Once the water has undergone this process, it is stored in a separate tank with guppy fished who feed on mosquito larvae that usually appear on still water.
