The NIFT campus used to require 15 water tankers per day. After implementing rooftop rain water harvesting to three working borewells and to one abandoned bore hole in July-2011, the water tankers supply reduced to 8 tankers from 15 per day and at present to Zero. The cost incurred for implementing was Rs 5 lakhs and the revenue saved is Rs 30 lakhs per year with almost zero maintenance required.
