Water Performance
Fresh water consumed at TCS comes from municipality supply, borewells, tanker supply and
a small fraction of packaged drinking water procured at some sites. A source-wise breakup
of the 1.6 million kL of water consumed in FY 2011 is shown in Figure . Other than the
groundwater aquifers that the on-premise borewells and tankers tap into, no other water
sources are impacted.
