How to Estimate Water Footprint for IT Companies?

Published on by in Business

I am a sustainability and environmental engineer working for L&T. 

I am looking for ways to reduce the water footprint at organisation level. 

Where can I find data for water consumption per person for IT companies and design centres? 

How does the water consumption differ based on the cooling systems the companies are using? If you have any data or formulas to estimate the water footprint, please share.
