The East Kolkata Wetlands were designated as a ‘Wetland of International Importance’ in 2002. The East Kolkata Wetlands are often called the ‘kidney of Kolkata’ because they are a natural waste water treatment for 680 million litres of raw sewage from the 120 million inhabitants of the city every day. The wetlands reduce the wastewater costs to almost zero.
