RO systems waste almost two-thirds of the water that comes for purification into the system, and hence they are not very environmental friendly. Having a central water treatment facility to deliver potable tap water makes much more sense for an institute like us. At IIT Gandhinagar​, we have successfully developed and stabilized our own water treatment facility and the complex distribution network of four separate water content (fresh water from supply, harvested rainwater, recycled water, and bore well water). We have been measuring and monitoring water quality on a daily basis and the water parameter are within the standards set by Bureau of Indian Standards (BIS) for potable water.
