Pallikaranai wetland in makeover mode

Eco-restoration of a portion of Pallikaranai marshland is currently under way. Once completed, it will increase the roosting area for birds, and also help in improving ground water table in nearby residential localities.

Work is under progress on about 100 acres of land near the southernmost point of the marshland. The area lies behind the nearly-400 acre ELCOT Special Economic Zone on Perumbakkam Main Road which connects Velachery Main Road at Medavakkam and Rajiv Gandhi Salai at Sholinganallur junction.

Forest department officials said, at present, mounds were being created by scooping out earth. The dug out parts had accumulated water due to the recent rains resulting in a profusion of fish and snails that in turn attracted birds.

The Pallikaranai wetland is one of the most important ecosystems in the metropolis. The marshland was originally spread over nothing less than 5,000 hectares and has now reduced to around 500 hectares due to indiscriminate construction and dumping of garbage.

An announcement in the policy note of the State government’s forest department last year set the ball rolling for the restoration project as well as the creation of a conservation authority.

The completion of the eco-restoration project will take five years and cost about Rs. 15 crore. However, it was not until early this year that preliminary work on the wetland began.

A water course spread over two hectares is being spruced up. Water channels that transport run-off during the monsoon from Perumbakkam and other areas to the Okkiyam Maduvu through the marshland are also being deepened and desilted.

Not only will this prevent flooding of localities on either sides of Perumbakkam Main Road, but also increase the level of water inside the 100-acre area, an official said.

A bund for a distance of more than 3,000 metres is being developed and when completed, nature lovers will be able to walk along the periphery.

An observation centre from where visitors can watch the birds will come up inside the core area of Pallikaranai marshland.

Also in the pipeline is an interpretation centre where photographs of birds that visit the marshland will be displayed. This will encourage schools and colleges to conduct educational tours and also raise awareness among the public about the rich flora and fauna, the official said.

Sources said a few thousand saplings of Arjuna (neer maththi), Portia (poovarasan), bamboo (moongil) and rosewood (sisu) would be planted here.

According to K.V.R.K. Thirunaran of The Nature Trust, nothing less than 127 varieties of birds have been sighted at Pallikaranai, significantly higher than the number at Vedanthangal.

This went to prove the diversity and importance of the wetland, he said.

Hey guys!

Anyone know anything about the Sewage Treatment plant (36 MLD) that was proposed to come up in Sholinganallur (somewhere near ISKCON? What is the status?

Need to invest in property in the area and this uncertainity about the STP is ruining everything.

Thanks in advance.

Thank you Kannan Sir. I know a tender was up in 2010 and then it got shelved. Is this finalization a recent development?

22 C approved for this project.

DEE-TECH pvt ltd is the company building it.

Expected to complete in 2014.

On New Kumaran Nagar, Entrance via KK Salai (ECR link road)

Thank you cofee, for your input.

Gentlemen, need some serious help here.

If I've understood correctly, the sewage treatment plant (STP) is coming up in the circle marked in red.

The property which we are considering to invest in is marked by the green dot.



What are the implications of having the STP located nearby? Is it something to worry about?

Simply put, should we not invest because of the upcoming STP? Completely satisfied with the property otherwise.

Looking forward to your answers guys. Real dilemma.

Looks like it is at a reasonable distance away from STP.

If you are getting a good deal proceed with it.

BTW what is the size of the land you are buying.

Once many houses come nearby the smell may not travel that far.

[kannan infratech]

Anekho

Please check CRZ compliance issue - 100 meters from the High Tide Line of B Canal.

You may not get official permission to build, if it falls within.

The smell from STP once operational is a possibility esp when the wind blows from west to east.

Kannan Sir is correct.

I forgot about CRZ & Aquifer recharge issue.

The site you are pointing is in aquifer recharge zone I think the minimum site has to be approximately 440sq meters (over 2 grounds) and you will get FSI of only 0.8.

On top of that if the site is with in 100 mts of the canal you will not get building approval.

Please consider carefully.

ECR side is full of headache due to CRZ & Aquifer recharge.

Fifth reservoir for city’s water needs, soon

In its efforts to create a new reservoir in Tiruvallur district, the Water Resources Department (WRD) will soon float tenders to start work on linking two water bodies in Kannankottai and Thervoikandigai, which come under the Gummidipoondi taluk.

The proposed reservoir will be able to store one thousand million cubic feet of water, when it is filled twice — equal to one month’s drinking water supply in Chennai. This will serve as the fifth reservoir to cater to the water needs of the city, and will also store Krishna water from Andhra Pradesh.

According to WRD officials, a detailed report for the project, which is worth Rs. 330 crore has been prepared. A consultant has been appointed to conduct environmental studies and get clearance from the State Environment Impact Assessment Authority for the project.

“We expect environment clearance to be obtained by the end of this month. We plan to float tenders for the work by mid-September,” an official said.

The new reservoir, which will have a water-spread area of nearly 1,100 acres, will be located 14 km from Uthukottai, the inter-state border of the Kandaleru-Poondi canal.

Of the nearly 1,300 acres of land required to implement the project, nearly 600 acres are government land.

The process to obtain ‘enter-upon permission’ from the Tiruvallur collectorate is also underway. A separate unit is being formed along with the collectorate for the land acquisition process.

About 700 acres of ‘patta’ lands have to be acquired and nearly Rs.170 crore has been set aside for land acquisition. “We plan to create an earthen bund at a length of 7.1 km and a height of up to 14 metres using excavated sand,” said an official. An 8.3 km-long canal will also be formed and linked with the Kandaleru Poondi canal, to divert Krishna water to the new reservoir.

To create the canal with a capacity to carry 1,000 cubic feet per second, nearly 200 acres need to be acquired. Of this, nearly 55 acres belongs to the forest department and the WRD is in the process of seeking permission to use their land.

Besides serving the city’s drinking water needs, the new reservoir will also help recharge groundwater in several villages, including Karadiputhur, Poovalambedu and Periapuliyur.

Thank you Kannan-ji and Cofee, appreciate your inputs. Currently putting the investment on hold. Really don't want to wake up the sight and smell of a STP every morning.

Funnily though, I'm not able to find the news about the tender being finalized anywhere! Also emailed DEETECH but received no reply.

Water Reservoirs of Chennai


1. Poondi
2. Puzhal(Red Hills Reservoir)
3. Chembarambakkam
4. Cholavaram
5. Proposed (A.Kannankottai B.Thervoikandigai)

There was a earlier proposal to have Chengalpattu lake(Kolavai lake) as the fifth reservoir. What happened to that?

[natarajan1986]

That is the only lake looking very clean and no bath or vehicle wash.Can you guess it is used by some coke or pepsi company water needs

[krishnaswamy]

I have read some reports earlier Kolavai lake is declared as unfit for drinking purpose.
see the latest news, that it might be restore it.

Ahead of monsoon, Chennai city gears up to desilt waterways

WRD to take up Rs. 4.43-crore project next week; over 70 km to be cleaned up by end of October

“We expect to obtain the government order in a week. We have split the work on the stretches into 71 packages to simultaneously clean up the entire length before the onset of the monsoon by October-end,” said an official.

The department has begun de-weeding and desilting three waterways – Otteri Nullah, North Buckingham canal and Virugambakkam canal – running to a length of nearly 35 km under the Jawaharlal Nehru National Urban Renewal Mission.

The Cooum and Adyar rivers will also be cleared of waste and weeds

Tardy monsoon: Chennai water table rises only marginally

http://www.thehindu.com/news/cities/...cle3828935.ece

[kannan infratech]

There are lots of individual houses / street row houses along the waterways which are not yet connected to CMWSSB sewer lines.

Most of them are encroachers. It is a political decision. Giving them connection will give Legitimacy to these encroachers.

TNEB did similar mistakes and they have cable TV / dish connections too.

Only legitimate owners should be allowed.
