To reduce its consumption of fresh water, the Chhatrapati Shivaji International Airport (CSIA) has set up three sewage treatment plants. The plants recycle 25 per cent of water used by every passenger, which is then utilised for toilet flushing, cooling and in the airport’s green spaces.
Speaking on the sidelines of an event to mark World Environment Day on Sunday, a Mumbai International Airport Pvt Ltd (MIAL) spokesperson said, “Fresh water is required for airport activities such as concessioners, cooking, drinking, cooling tower, etc. We can’t substitute fresh water requirement by treated sewage totally, but fresh water requirements in some activities, such as toilet flushing, gardening and cooling in HVAC, can be substituted by treated sewage. The sewage generated from terminal buildings and landslide activities are being treated at state-of-art STPs for Terminal 1, 2 and cargo.”
The event on Sunday was hosted by GVK CSIA, which administers MIAL. At the programme, 30 students from Matoshri Vidyamandir and Rajnigandha Madhyamik Vidyalaya took an oath to shield the environment from destruction. The Peepal, The Girl And The City, a book on environment written by Kalyani Majumdar, was also launched.
Majumdar said most people are not aware that plants might die due to excessive watering. In the form of a story of a girl who befriends a plant, her book talks about choosing the right plants and the most effective means to grow them. “I am waiting for the day when trees will start talking, so people will stop hurting them”, said Majumdar
Several botanical and bonsai species were displayed at the event.
Sachin Tawde, deputy manager of Project Landscaping at GVK, said not a lot of people know that succulent plants are a great choice for pots, as they require very little maintenance and less space. “In a single pot, almost five different plants can be grown, which adds to the beauty of your house too,” said Tawde.
Ecowings, a company that manufactures upcycled products, had displayed a range of laptop bags, diaries and key chains — all manufactured from tyres — at the event. Upcycling involves using waste material to create products of a higher value than the original.
“Tyre is a good substitute for leather. While it is difficult to stitch tyres, the manufactured product has a long life, making them very sustainable,” said Himanshu Sharma, sales executive of Ecowings.
