Delhi Water Woes: DJB Blames DDA for Kirari Floods

In a report submitted to the National Green Tribunal (NGT), the Delhi Jal Board (DJB) has asserted that waterlogging and stagnant wastewater in northwest Delhi's Kirari stem from external issues, such as obstructed natural drainage and a lack of stormwater management, rather than deficiencies in its sewage system. Kirari's rapid, unplanned development has resulted in over 100 unauthorized colonies lacking adequate sewerage and stormwater networks.

During monsoon seasons, the limited capacity of the KSN drain leads to severe sewage overflow and significant waterlogging. Media reports concerning stagnant wastewater and flooding, particularly in Sharma Colony, prompted the NGT to take suo motu notice. The DJB's report indicates that while sewage networks are in place in areas like Sharma Colony, they remain inoperational due to the absence of a trunk sewer for outflow management.

The DJB further criticized the Delhi Development Authority (DDA) for filling low-lying areas with waste and inert materials from landfill sites without providing drainage solutions. The board stated its sewage network is designed only for toilet waste. In response to waterlogging concerns, the DJB clarified that it is due to stormwater mixed with surface runoff, with drain construction falling under other departments.

Significant progress is being made on infrastructure to address these issues. The trunk sewer line, when completed by DJB, will channel sewage to the nearly finished Pratap Vihar wastewater pumping station, with treatment planned for the Rohini sector 25 STP. Additionally, six projects under a Union government initiative are underway to mitigate flooding, including drain construction across various colonies and along railway lines.
