Though the rainfall remained very normal in city, the downpour along the Western Ghats led to copious inflow into the Noyyal resulting in the major water bodies in and around the city witnessing a marked improvement in storage despite blocks and encroachments in the water ways.
Rain as a source and with copious feed from Noyyal river, storage in the eight major tanks and water bodies has gone up.
Project co-ordinator of Siruthuli K. Mylswami said that of the eight tanks, two major tanks within the city - Ukkadam big tank and Valankulam - could accommodate another 10 million cubic feet of water.
With the downpour in Siruvani hills leaving the Noyyal in spate, the storage in Narasampathy fed by Chithirichavadi section of the Noyyal had improved to 70 per cent. Similarly, Selvampathy and Muthannankulam were also fast reaching the 75 per cent storage mark.
There was also steady inflow into Selvachinthamani tank. While the Ukkadam big tank had 75 per cent storage, storage in Kurichi tank was only 60 per cent. When the other tanks reached the brim, Kurichi in the tail end of the chain of tanks in the Noyyal river system was expected to improve.
The only deplorable condition was with that of Valankulam and Singanallur tank. Valankulam gets filled up only because of rain and the influx of waste water. The Singanallur tank though fed by Sanganur canal was also getting a substantial quantity of waste water. If the rain continues at this rate for another 10 to 12 days, then the storage in all the water bodies is expected to touch the full level.
Nature enthusiasts express concern over some of the tanks having encroachments in the form of hutments.
If the administration's ambitious plan of a slum-free city had taken off by now, then allowing the water bodies to reach the brim would not have been an issue.
The plans of relocating the slum dwellers from the hutments along the water bodies to the multi-storeyed dwelling units failed to take off because of the issues evolving around the safety of these structures constructed under the Jawarhalal Nehru National Urban Renewal Mission (JNNURM) at Ammankulam and Ukkadam, the nature enthusiasts said.
Mr. Mylswami pointed out that the storage was being constantly monitored by Collector M. Karunakaran and Corporation Commissioner T.K. Ponnusamy.
To avoid water logging and inundation of roads during rain, Siruthuli had embarked on a mission to identify pockets where water logging happens so as to have Roadside Rain Water Harvesting structures at these places. Managing Trustee of Siruthuli Vanitha Mohan had instructed her team to identify pockets where the rainwater could be conserved/harvested.
Identification of places had already been done and with the consultation and consent of the Collector and the Corporation Commissioner, works for the same would begin next week, Mr. Mylswami said.
