The city is suffering with water crisis for the past few years; but citizens have not taken initiative to harvest rainwater. Only 1,411 of over 7.2 lakh registered properties have opted for rainwater harvesting systems in the city.Rooftop rainwater harvesting has been made mandatory for all new buildings that have come up since 2007. The civic body gives 10 per cent concession to property holders who implement any two of the three techniques – solar heating, garbage segregation and vermicomposting, and rainwater harvesting. 5 per cent concession would be given for implementing any one technique.
