The Delhi Jal Board (DJB) was able to add capacity of only one million gallons per day to the sewage treatment plants (STPs) and laid only 900km of sewer lines during 2007-2012, the Comptroller and Auditor General of India (CAG) pointed out on Tuesday.

“The DJB incurred an expenditure of Rs. 1634.18crore (but) could not utilise grant-in-aid received under JNNURM fully. It had not prepared any perspective plan and could only treat 367 million gallons per day (54%) out of 680 million gallons of sewage generated per day in Delhi,” the CAG report said.

A test check at 15 out of 32 sewage treatment plants revealed that all these plants were working below their capacity as the DJB was unable to create a system to carry and feed them with enough sewage.

The audit report said the Delhi State Industrial Infrastructure Development Corporation, which takes care of industrial treatment of pollutants in the capital, failed to complete work on four of the 15 common effluent plants in December 2012, resulting in untreated sewage flowing into the Yamuna.

The corporation was originally scheduled to complete work on the effluent plants by 1998. Nearly 1,27,69 million tonnes of hazardous waste generated by these common effluent plants during treatment was lying on the premises itself as on November 2012, creating a threat to the environment.

The audit team found substantial wastage of potable water at the Chandrawal treatment plant due to leakages in pipelines carrying water to the underground reservoirs, which were 57 years old.

The pipes had not been repaired due to budget constrains. “Inaction on part of DJB in plugging the leakages indicates insensitivity towards wastage of precious potable water,” the report pointed out.

The CAG pointed out that as against the norms of the ministry of urban development, the non-revenue water (water which does not earn revenue for various reasons) was more than three times the prescribed limit of 20% of total.
