Removal of water hyacinth, obstructions from marsh soon
CHENNAI: The removal of water hyacinth and other obstructions in the Pallikkaranai marsh will be taken up shortly, as part of the Public Works Department's measures to address the problem of flooding in and around Velachery.
The work, which will cover the portion of the marsh up to the intersection of the Velachery-Tambaram road and Thoraipakkam-Pallavaram radial road, will go on till the northeast monsoon is over.
The department has just finished removing silt from Veerangal Odai and forming a watercourse to allow fre flow of water from the western side of Velachery-Tambaram road to the marsh, according to a senior PWD official.
Originating in Nanganallur, the Odai flows through Madipakkam, Adambakkam and Ullagaram-Puzhthivakkam. It abruptly terminates near Ullagaram-Puzhuthivakkam, and the PWD has formed a watercourse to facilitate the water flow to the Pallikkaranai marsh. An earthmover mounted on a floating platform was used to lay the two-km-long course, with a width of 30 feet and a depth of three feet.
Earlier, the Odai drained into Velachery lake, but over the years, residential colonies such as Srinivasa Nagar, Ram Nagar and AG's Colony came up on the lake's water-spread area. Because of this, the colonies were flooded more frequently than others.
During the next northeast monsoon, Velachery and surrounding areas will not face the flooding seen this year, according to the Local Administration Minister M.K. Stalin. The minister told The Hindu on Friday that a lack of drainage courses and the inadequate carrying capacity of the existing courses were responsible for the flooding. The government was addressing the twin issues, he said.
