COIMBATORE: The much-awaited works to lay sewage lines for the Rs.377-crore underground drainage scheme took off in the city on Monday after a delay of 10 years.

The Corporation also made it clear that the public would have to brace for some inconvenience as roads would have to be dug to lay the lines. But, the best of efforts would be made to reduce the inconvenience.

Rural Industries Minister Pongalur N. Palanisamy launched the works to lay the pipes and construct sewage chambers in the presence of Mayor R. Venkatachalam, Corporation Commissioner Anshul Mishra, Deputy Mayor N. Karthik and councillors and officials of the civic body.

The Commissioner said that the works begun on Monday were for six of the eight zones for which the sewers scheme was being implemented. The cost of these works was estimated at Rs.191 crore.

In the phase just begun, the contractor would lay 510 km of main lines, out of the total 635 km under the scheme. Another 680 km of lines for house connections (from the main lines) would also be laid. This phase would cover 53 out of the total 72 wards in the city.

“Out of the total 30 months for the project implementation, two have already elapsed. The aim is to complete the project within the time-frame,” Mr. Mishra said.

“The scheme is important from the point of view of hygiene as people in many areas are connecting their toilet lines to the storm water drains,” he said.

Appeal

The Commissioner requested the public to show some patience during the implementation period.

“This is a kind of project that will cause inconvenience, but will provide a permanent solution to the present problems in sewage disposal,” he said.

The Corporation would have a sub-plan to minimise inconvenience to the people. “We will involve residents’ welfare associations, councillors and the contractor in every area covered under the scheme to devise ways to avoid problems. They can decide on which area should be taken up first so that vehicle and pedestrian movement is not affected,” Mr. Mishra said. Discussions would be held with the traffic police also on digging roads without impeding traffic flow.

4 days of water supply realised from Kandaleru

About 600 cusecs received on Monday

 


Metrowater confident of maintaining daily supply

Storage level at Veeranam tank is also increasing


CHENNAI: The city has realised 104 million cubic feet of water (mcft) from the Kandaleru reservoir in Andhra Pradesh since Friday evening. This is equal to four days of water supplied by Chennai Metrowater.

Officials of Water Resources Department here said Uthukottai, the inter-State border of Kandaleru Poondi canal, received about 600 cubic feet of water per second (cusecs) on Monday. At present, about 1,500 cusecs of water is being released from Kandaleru reservoir and the discharge is expected to be stepped up in a few days.

As there was no rainfall in the region where the canal traverses, seepage of water in the almost dry canal bed could not be avoided. However, this would reduce in a few days, the officials said.

Officials of Chennai Metrowater said Poondi reservoir, which is being used as a storage point of the water discharged from the reservoir upstream, received an inflow of about 510 cusecs on Monday. The storage level in the Poondi reservoir has increased from 124 mcft registered two days ago to nearly 200 mcft.

Once a comfortable storage level is reached in Poondi reservoir, the water received would be diverted to other three reservoirs that feed the city. The four reservoirs have storage of only 2,429 mcft as against their capacity of 11 tmcft. Last year, the total storage was 3,553 mcft during the same period.

However, Metrowater is confident of maintaining its daily supply of 640-650 million litres of water to Chennai with the available resources.

Meanwhile, the storage level at Veeranam tank is also increasing with a steady inflow from Lower Anicut. Metrowater draws about 180 mld from the tank to augment the city supply.

The water agency proposes to reduce the extraction from borewells in Neyveli aquifer following the boost to the storage of the reservoirs.

The officials said it is, however, premature now to assess the volume of water to be received from Andhra Pradesh under the Krishna Water Supply project.

River-linking channel excavation in full swing

In progress: The channel to take Tamiraparani surplus water to Karumaeniyar and Nambiyar being dug near Pirancherry.

TIRUNELVELI: The usually tranquil stretch south of Piraancherry near Palayamkottai is now busy with nearly a dozen humming heavy earthmovers and good number of tipper lorries carrying the excavated boulders as work on the construction of the 72 km-long channel to take the surplus water of Tamirabharani to Karumaeniyar and Nambiyar has moved to top gear.

The project has been designed by the State Government on a massive outlay of Rs. 369 crore to take the excess water of the perennial river to the rain shadow regions of Nanguneri and Radhapuram taluks in Tirunelveli district and Sattankulam taluk in Tuticorin district.

After it was estimated that 13,758 million cubic feet (mcft) was wasted during every rainy season, it was decided to excavate a flood carrier canal from the existing Kannadian Channel at Vellankuzhi near Cheranmahadevi in Tirunelveli district to the drought prone area of Nanguneri, Thisaiyanvilai, Radhapuram and Sattankulam by interlinking Tamirabharani, Karumeniyar and Nambiyar rivers.

From Kannadiyan Channel, the Tamirabharani’s surplus water of only 2,765 mcft would be taken to the irrigation tanks at Suviseshapuram, Pattancherry, Vijayaachchampaadu, Singachaavadi, Subramaniyapuram, Puthukkualm, Kalkulam, Nanthankulam, Yerumaikulam, Avichchaankulam, Aayankulampadugai, Aanaikudipadugai, Ilaikulam, Kadakulam, Puththantharuvai and M.L. Thaeri.

Connecting channels

Connecting channels would be dug between the flood carrier channel and the Karumaeniyar (5,350 metre), the Nambiyar (6,700 metre) and the Manimuthar (2,500 metre). Two check-dams at Maelodai and Keezhodai on the Sattankulam- Nazareth stretch would be constructed.

Once this Rs. 369 crore-project, to be executed in 72 packages, is completed, the surplus water of the Tamirabharani will irrigate 5,059 hectares (12,500 acre), quench the thirst of several lakhs of population and dramatically improve the groundwater table and provide succour to the crops of this rain shadow region.

In the first package, contract for excavating the channel for 20 km has been awarded to a few companies which are working round-the-clock as they have to complete it before 30 months from the date of commencement.
