Three years ago, Marriott International had a problem in India.
Water tankers arrived daily at its 32 hotels there, but often with sand and contaminants or with less water than promised. The uncertainty made it hard to manage costs and risk, said Denise Naguib, Marriott's vice president for sustainability.
While searching for solutions, Naguib's phone rang. It was Emilio Tenuta, Ecolab's vice president of corporate sustainability. He wanted Marriott to test a new "water risk monetizer" that the St. Paul water filtration and sanitizing company just co-developed with Microsoft and environmental data firm TruCost.
The free tool would allow Marriott to analyze how much water scarcity and pollution cost their operation.
The upside for Marriott? To make the water safer and to help meet the corporate goal of reducing water use by 20 percent by the year 2020.
For Ecolab, it was a chance to find problems that could be solved by buying Ecolab equipment.
Marriott solved several issues with the project. For example, the company bought an Ecolab automated water-boiler treatment system for the JW Marriott Hotel in Pune, India. The purchase saved 1.1 million gallons of water in six months.
"The monetizer was a phenomenal solution for us," Naguib said. "It was huge."
