Chennai's water management system faces critical challenges

A recent study by the NGO Arappor Iyakkam highlights serious issues in Chennai's water management, particularly concerning the Kosasthalaiyar, Cooum, and Adyar rivers. The study claims the city is unprepared for monsoon flooding and droughts, urging reforms. The Greater Chennai Corporation disputes these claims, stating that it regularly desilts 35 canals and is implementing various water management initiatives. Officials emphasize ongoing projects to restore lakes and improve drainage systems. The study also points to declining green cover and urbanization's impact on water retention. It recommends measures like decentralised sewage treatment and better rainwater harvesting to enhance the city's water management and resilience against climate change.
