Delhi’s Indira Gandhi International Airport (IGI) airport takes a big step towards water conservation! Apart from being among the world’s leading airport, the Delhi airport is also adopting solutions for environment protection and water conservation. For environmental protection, various measures have been taken along with green cover plantation across the airport. At the same time, a new automatic irrigation system has been set up at the airport for water conservation, according to a Dainik Jagran report. With this system, around four lakh square meters of area is being irrigated from four underground sewerage treatment plants built there.
