The Delhi Jal Board (DJB) has raised concerns over mass fish deaths in the Najafgarh drain, which flows into the Yamuna River, prompting a call to the Haryana government to trace and address the source of untreated effluents. The DJB noted that Haryana's departments are already working on treating the untreated discharges. As part of the 'Mission Sahibi' initiative aimed at rejuvenating the Yamuna, the sewage treatment capacity in Gurugram will be increased by 90 million litres per day, and a new 227 million litres per day plant is planned for Faridabad, with a completion target of March 2028. Additionally, the Gurugram Metropolitan Development Authority (GMDA) will utilize drone surveys to identify illegal sewage discharge points along the Badshahpur drain, which contributes to the Najafgarh drain's pollution. Water expert Diwan Singh emphasized the need for comprehensive treatment solutions for the Sahibi River system, involving collaboration among Rajasthan, Haryana, and Delhi to effectively tackle the pollution crisis.
