What I really wanted after this luxuriously heavy meal was to take a nap, but something more informative was the order of the day. I was about to go on a tour of the property, with Chief Engineer Mr Narayanaswamy Ramamoorthy, where I would get all the answers about this mysterious term responsible luxury. I was told that ITCs environmentally sustainable measures began even before the construction of the present building started rather than cutting trees within property limits, the team transplanted them around the premises a sustainability measure that seems so simple, but one that many large companies overlook. Our first stop was the sewage treatment plant of the Grand Chola, which was a two-minute walk from the main entrance. Hundred per cent of the waste water of the hotel is treated through the plant and recycled for a multitude of uses such as horticulture, flushing and campus cleaning. The hotel also has areas for water harvesting, which help retain all the storm water catchment on-site. Along with these measures, even the fixtures inside the hotel were put in place to reduce water usage, which lowers the hotels water usage by as much as 35 per cent when compared to other buildings just like it The vegetation around the hotel, which is grown vertically so that more plants can be potted in less space, is also low-maintenance to help minimise water usage. Water wastage is a big concern for the people at ITC Grand Chola and it was a privilege to see persistent effort to combat it at every step. I also visited their facility for in-house drinking water purification. Deemed SunyaAqua (pronounced shunya aqua), a path-breaking initiative of what they call zero-mile water. A mineral water bottle pollutes not just because its plastic. The process of shipping and delivering such bottles to hotels by fuel-guzzling trucks leaves a huge impact on the environment.Since this water is purified in- house, SunyaAqua travels exactly zero miles, thereby creating no carbon footprint whatsoever. This is the water inside every glass bottle in ITC Grand Chola. Their process does not just remove contaminants, but also infuses the water with the goodness of tulsi, fennel and cinnamon.
