The Veeranam tank in Cuddalore district — a vital source of Chennai’s drinking water supply — will be desilted and cleaned to increase its storage capacity.

Making an announcement in the Assembly on Thursday, minister of Public Works Department (PWD) K.V. Ramalingam said the work would be taken up at a cost of Rs. 40 crore. The Vadavar channel, which brings water to the tank, will also be rejuvenated. This will ensure more water for Chennai residents and take care of irrigation needs in the neighbouring areas.

According to PWD sources, though the tank has the capacity to store 1,465 million cubic feet (mcft) of water, nearly one-third of the water body is filled with silt. Once the work to desilt and deepen the tank is completed, an additional storage of 200-250 mcft will be available to Chennai residents.

With the release of Krishna water suspended for the time being, to carry out preliminary work at the damaged portion of Kandaleru Poondi canal near Ubbalamadugu, water from Veeranam tank is vital to maintain daily supply.

The minister said water bodies on the fringes of Chennai would be rejuvenated and developed as recreational spaces. Initially, the lakes in Ambattur, Madhavaram and Korattur would be modified with parks and footpaths.

The surplus courses of Porur and Kolathur tanks will be improved at a cost of Rs. 73.01 crore under the Jawaharlal Nehru National Urban Renewal Mission this year.

The minister also said the new Bangaru channel that brought surplus water to Chembarambakam reservoir would be improved at Rs. 1.15 crore. Funds amounting to Rs. 34.55 crore have been allotted to construct check-dams across the State.
