The Chennai Corporation has asked contractors to complete construction of stormwater drains under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) by June next year.

A total of 12 watersheds are being covered under the project and 13 contractors have been awarded the work. The original deadline for the project, which is in various stages of implementation, was 2013.

Sources in the civic body said that a meeting of contractors was convened on Monday and they were asked to finish the work on a war-footing. “If they are unable to complete it, we have told them that we would call for fresh tenders and get the works done. We have asked them to give in writing the reasons, if any, for their inability to complete the project by June, within three days,” the source said.

The stormwater drain network would cover a total of 15 canals, 147.19 km length of arterial drains, 229.37 km of feeder drains, and 95.61 km of collection drains.
