BANGALORE: The Kempegowda International Airport is making efforts to paint a ‘green’ picture for those flying into the city.”Our aim is to build an airport in a garden and not the other way round,” said Hari Marar, President, Airport Operations. He was talking to reporters about sustainable practices adopted by the airport. “We are trying to conserve all the resources that are available, especially water and power,” he explained.
The airport situated on the outskirts of Bangalore has 100 acres of green cover, a 100,000 square meters of lawn and 135 varieties of trees and plants.
“We bring in plants and keep them for a month in the green house under a 24 degree Celsius monitored temperature. This allows plants to survive inside the terminal buildings as well,” said Lakshminarayan S, VP, Engineering and Maintenance.
The airport also chooses its flora and fauna carefully. “At any time of the year the airport is a bed of colours. We choose our plants according to the changing seasons and keep changing them often,”he said. With the city making every effort to conserve rain water, the airport has set an example for others to follow. “We have built rooftop water storage points. We get around 2 MLD of water due to rain water harvesting,” he said. The efforts had helped increase the groundwater levels in the area. “Earlier, we would get 100 kl of water per day but this has now gone up to 320 kl per day,” he added.
The airport has also rejuvenated four wells in the area. “There are six wells in the area, built by the original owners. Instead of letting these dry, we kept them alive, maintained them and now use them in case of water shortage,” explained Lakshminarayan.
The in-house Sewage Treatment Plant with a capacity of 2 MLD provides for the water used in many parts of the airport. “We treat the waste water collected from all facilities in the water. The water is then reused for the air-conditioning system and also for firefighting purposes. The sludge is used as a bio-fertiliser,” he said.
The airport hopes that their efforts in protecting the environment increase with the expansion of the airport.
Second runway by 2018?
The second runway that is part of the expansion plans of the airport should be up and running by 2018, said Hari Marar, President - Airport Operations. “The second runway is linked to traffic volume and we expect it to be complete and ready to be used by 2018,”he said.
