State govt to begin work on canal project

The Tamil Nadu government would soon begin work on building a diversion channel from Virugambakkam-Arumbakkam canal to Cooum under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM).

The proposed diversion channel would prevent occurence of flooding in the canal whenever surplus water is released from the water bodies in Porur and Chembarambakkam. Owing to the limited carrying capacity of the canal, residents of surrounding areas, including Chinmaya Nagar and Virugambakkam suffer flooding during rainy season.

The central government is learnt to have approved the revised detailed project report (DPR) for the work recently and following this, the Water Resources Department (WRD) may start work in a couple of weeks.

In a bid to alleviate inundation, the WRD plans to construct a 2,200-metre long canal to divert the excess flow of 600 cubic feet per second from the Virugambakkam-Arumbakkam canal.

The diversion channel will travel via Kaliamman Koil Street, Koyambedu and Jawaharlal Nehru Salai and cross Poonamallee High Road to be linked with the Cooum.

The design of the channel, which would be four-metre wide and two-metre high, has been modified taking into consideration the proposed flyover on Jawaharlal Nehru Salai junction. Work is set to be completed in seven to nine months.
