New Delhi: Only 54 per cent of the total sewage generated in the national capital is treated by Delhi Jal Board and the rest 313 MGD of waste is released into Yamuna untreated. The Comptroller and Auditor General, in its report for the fiscal ending March 2012 which was tabled in Delhi Assembly on Tuesday, said that sewage management in Delhi was found to be "deficient" in various aspects.
"DJB was able to collect and treat only 54 per cent of the total sewage generated in Delhi whereas remaining 313 MGD of sewage was flowing untreated into Yamuna through storm water drains," the CAG said. It said the DJB has not prepared any perspective plan for sewage management for 11th Plan.
As regards treatment of industrial sewage, it was observed that four out of 15 Common Effluent Treatment Plants (CEPTs) which were to be completed by 1998, were not completed as of December 2012 resulting in industrial sewage flowing into Yamuna untreated.
