CRYING FOR ATTENTION: The canal inside the Guindy Industrial Estate is in need of desilting.

CHENNAI: Although various government departments are gearing up for the northeast monsoon, stormwater drains and waterways passing through industrial estates in and around Chennai are yet to be spruced up.

The unit-holders fear that the impact of the monsoon will be similar to the one witnessed last year, owing to the lack of improvement works to arrest inundation.

Members of the Ambattur Industrial Estate Manufacturers Association complained that two canals that carry rainwater from the estate and flow through Korattur and Mogappair had not been desilted. Though the stormwater drain network in the estate has been strengthened, it is not enough to prevent inundation, an industrialist said.

With the National Highways Authority of India, which is constructing an elevated corridor through the estate as part of the Chennai Bypass Project, taking time to provide stormwater drain in the area, the AIEMA members expect the 3rd Main Road, where work is under way, to be water-logged. Last year many units on lanes off the 3rd Main Road had to be closed till the water drained off. Nearly 30 per cent of the 1,500 units in the estate were affected during the last monsoon, he said.

The grievances of unit-holders in the Kodungaiyur and Perungudi industrial estates are also similar. Noor Saied, president of the Perungudi Industrial Estate Manufacturers’ Association, said, “if it rains as heavily as it did during the last northeast monsoon, the situation would be no different as stormwater drain network is yet to be provided along Rajiv Gandhi Salai by Tamil Nadu Road Development Corporation. The water from the 6-lane IT corridor will flood the estate.” Last year, the estate remained under sheets of water for several days forcing many of the industrial units to close down, he said.

K. V. Kanakabaram, president, Industrial Estate Manufacturers Association, Guindy, said the estate gets rainwater from Alandur, Adambakkam and St.Thomas Mount besides surplus water from the Chembarambakkam lake. Several of the units that are not able to function as a result of inundation suffer huge production loss. Residents of the nearby Labourers Colony and Defence Colony also get affected.

An important water carrier, which runs through the estate and brings water from Alandur, has been reduced in size as it has not been desilted despite repeated representations, he said.

Entrepreneurs at the Thirumazhisai industrial estate hope that this year they will be in a position to manage flooding as the estate is set to be provided with an 8-km-long SWD network at a cost of Rs.6.5 crore by September-end. V. Venkatesh, Director of Auto Ancillary Industrial Infrastructure Upgradation Company, said that following the widening of Poonamallee High Road, the level of the culvert that carried rainwater to the Chembarambakkam lake had been lowered. This may obstruct free flow of rainwater. Two ponds in the Thirumazhisai estate must also be desilted. Officials of the PWD and the Ambattur Municipality, however, say they plan to desilt canals under their purview before the onset of the monsoon.
