The Indian Institute of Technology-Delhi, which was assigned the task of preparing a drainage master plan for Delhi, is awaiting relevant data from the Delhi government to help it complete its work.

IIT-Delhi was appointed the consultant for the project in June 2012 and was given 18 months to submit the report. The Delhi government had promised the institution 3-D digitised maps prepared by Geo Spatial Limited. But 13 months later, the IIT is still waiting to hear from the departments concerned.

“When we were appointed as consultants, we were told that they have digitised data that will be released soon. We are now being forced to go and seek the details from each department,” said professor AK Gosain, department of civil engineering, IIT-Delhi.

“Once we have complete the data, it should not take us more than six months to simulate it and look at the issues and come up with a new plan,” Gosain added.

While Delhi’s population has gone up from 62 lakh in 1981 to 1.67 crore in 2011, the city’s drainage system is based on the master plan finalised in 1981. No wonder, the drainage system is not able to cope with an almost three times increase in population and extensive urbanisation. There are about 5,000 drains - big and small - in Delhi and the majority of them are too old to be repaired or revived.

“IIT-Delhi has been tasked with revamping the system by keeping the existing the drainage system in mind. It will suggest which drains need to be widened, where do we need to construct new drains and how to connect the drains to ensure that storm water is channelised properly and the possibility of waterlogging is eliminated,” said a senior irrigation and flood control department official.
