The Delhi Jal Board (DJB) has formally requested the Delhi forest department's approval to develop a sewage network in unauthorized colonies situated on forest land. This proposal, submitted on March 13, is intended to address sanitation issues and environmental degradation in these areas. The DJB emphasized the urgency of the matter, citing the need to prevent pollution in the Yamuna River. Unauthorized colonies, particularly in regions like Sangam Vihar, Sainik Farm, and Chattarpur, are currently lacking adequate sewage facilities. The DJB's letter highlights that sewage generated from these colonies cannot be managed without the forest department's permission. The proposed infrastructure will be installed underground, ensuring no trees are harmed during the process. Currently, about 82% of Delhi has sewage coverage, leaving 18% without a proper system, primarily in unauthorized and slum areas. The Delhi Economic Survey indicates that there are 1,799 unauthorized colonies in the city, with sewer lines laid in 1,235 of them. The DJB's initiative is in line with the National Green Tribunal's directives aimed at improving sewage management in the region.
