Five years' time taken by the government in appointing a committee and another seven years' time to appoint a consultant for prepartion of action plan coupled with non-furnishing of the essential data to the consultant delayed the process of putting a proper framework for looking into drainage problems in Delhi, the report said.
The CAG pointed that the existing drainage network of Delhi (Master Plan of Drainage 1981) was required to be reviewed and integrated with the Master Plan of Delhi (MPD) 2001.
The government appointed Head of the Civil Engineering Department, IIT Delhi, as consultant, after approval of the cabinet in June 2012, it said.
It was to commence work in July 2012 to be completed within 18 months and the terms of reference provided that the Master Plan for Drainage would be in consonance with MPD 2021, as well as Master Paln for Sewage, being prepared by the DJB.
And, since the essential data were not avilable with the Delhi State Spatial Data Infrastructure Project (DSSDI), all concerned agencies were directed to indepently carry out the survey and submit data to the consultant by December 2013, it said.
But, as the result of the ensuing delay, Delhi is still to have a dedicated Master Plan on Sewerage Rehabilitation.
The CAG also rapped PWD and the three municipal corporations of Delhi and other concerned agencies for not maintaining the requisite database of drains under their jurisdiction.
