  • How much of awareness do you see among hoteliers or hotel management to treat sewage? (Any data on sewage generated and real conscious efforts taken by the hospitality industry in India.)

Indian cities produce around 40,000 million Liter of sewage per day. Estimates suggest that around 10% of this sewage is generated from Hotel industry.

Over the last decade the hotel industry in India has seen an unprecedented growth. There are several international brands that have entered India with a vision to establish a considerable footprint. The intense competition has brought out the best in the Industry. An environmentally sustainable hotel is not just a catchy term anymore. For a mid or upper class hotel, establishing responsible practices for water sustainability has a tangible P&L impact. We have seen brands like ITC and Mahindra Holidays pioneer this movement. ITC Maurya is world’s largest hotel to get a LEED platinum certification. Club Mahindra is using our GREWA based systems to recycle and reuse upto 90% of the wastewater generated in their resorts. We have witnessed similar success stories across India and that makes us believe that proper treatment of sewage and reuse of waste water is a strategic priority for all reputed hospitality group.

  • Mention status of the current situation in terms of damage being done to the environment around. And what are the government norms to control it? upto what extend are these guidelines followed?

Historical data states that out of the 40,000 Million Liters of sewage generated per day in Indian cities only 20% is being treated, the remaining 80% sewage flows into the natural water bodies such as rivers, lakes and ground water. This poses a severe sanitation threat as well as threat due to contamination of water table with sewage water. The natural flora and fauna of the water bodies gets severely affected due to excess sewage, resulting in ecological degradation.

There are guidelines and enforcement systems in place by government to fight this problem. Government has laid down norms for treatment and reuse of swage in hotel industry. All hotels are required to adhere to a bare minimum treatment and recycle standard to get NOC for operations of Hotels. Local government bodies have also identified environmentally sensitive zones that attract tourists such as Mahabaleshwar and have laid down more stringent norms for Hotels and commercial establishment in these areas. Government has also clearly marked areas in vicinity of rivers called River Restricted Zones, where all Hotels have to adhere to zero discharge norms.

The guidelines are well laid down and in recent years we have witnessed a significant improvement in enforcement for the norms as well. However still there is a lot of betterment required to make sewage treatment and reuse of waste water a ubiquitous practice in Hotel industry.

  • Do you see a trend changing?

Yes for sure we see the trend changing. There are several leading indicators of the trend. Such as all reputed hospitality group have environmentally sustainable point as marketing pitch which is valued highly by international client base of hotels etc.

  • If yes is it because
    • Governing bodies playing a major role in this changing trend.
    • Or the hotel groups are now becoming more serious in adhering to the guidelines.
    • Or simply because of the long term profitability has been established by educating customers the benefits of sewage treatment or recycling waste water.
    • Or there is larger contribution of Green Building movement in India.

I would say that all the above factors have played a significant role in shifting the momentum towards responsible treatment and reuse of sewage water. Green building movements have played a significant role in popularizing environmentally sustainable development. The economics are changing in favor of sustainable practices. For all hotel groups the emphasis is on long term profitability thus recycle and reuse makes sense. The government machinery has also tightened up and is ensuring proper reinforcement of norms. Another significant factor is the availability of better and more efficient technology solutions for treatment and recycle of sewage such as GREYWATER that provide a hassle free and robust solution for Hotel Industry.
