On the 19th of October, 2019, the Geography students of Class XI, the EVS students of Class IX and the ESS students of IB did a field survey of the East Kolkata Wetlands to learn what happens to the 750 million litres of untreated sewage water that the city of Kolkata produces on a daily basis. We were rendered speechless when we realised how crucial this otherwise overlooked and fragile ecosystem is for the city. Doctor S. Ghosh and Professor S. Chaudhuri guided us through the trip and shared with us their immense knowledge of the subject.

During the survey, we first visited the Bantala Lock Gate, situated in the eastern fringes of the city, where one of the largest assemblages of sewage fed fish ponds is located. We then headed to the wetlands near Aquatica, beyond which construction is prohibited by law. On our way to Aquatica from the Bantala Lock Gate, we caught a glimpse of the Dhapa waste mound, a landfill where more than 80% of the city's solid waste is dumped.

The field survey provided us with an insight into the aspects of the city that are often ignored or taken for granted. It was an enjoyable and unforgettable educational experience.
