Enough in reservoirs to last till next monsoon

Enough in reservoirs to last till next monsoon: Metrowater officials - The Times of India

CHENNAI: The level in the Veeranam lake in Cuddalore is up to the brim following the heavy inflow but Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) officials say it does not mean any increase in the supply to the city. They, however, say the four reservoirs have enough to last till the next

On Tuesday, the level in the Veeranam lake was at 43.7 feet against its capacity of 47.5 feet. The inflow was 1,000 cusecs while the outflow maintained at 1,474 cusecs. On Wednesday, the inflow was 500 cusecs and the outflow 493 cusecs.

CMWSSB officials say only 180 Million litres per Day (MLD) is drawn from the lake for the city's needs. "Veeranam is primarily a irrigation lake from which we are drawing water for the city under a scheme. Of the out flow of 493 cusecs from Veeranam on Wednesday, 427 cusecs will go for agricultural use and 66 cusecs for Chennai," said an official.

Water from Veeranam reaches a pumping house in Settiya Thoppu near Cuddalore and goes to a treatment plant in Vadakuthu near Neyvelli. From there it reaches an overhead tank in Kadambuliyur and then, using gravity, 180 MLD is sent to the Porur headworks. "This then provides water to entire South Chennai," said the official.

Officials say the level in the four reservoirs supplying water to the city increased by 45% on Wednesday compared to Tuesday. On Tuesday, the combined storage was 4880 mcft against the capacity of 11,057 mcft. On Wednesday, it was 5039 mcft an increase of 159 mcft.

"The increase is mainly due to the rains. The average rainfall in Red Hills, Cholavaram, and Poondi is 325 mm for November. We have been receiving 2.3 thousand million cubic feet (tmcft) of Krishna water. This is expected to continue untill our reservoirs become full and we ask them to stop. This will ensure enough supply till the next monsoon," said the official.

With heavy rains lashing the northern districts, the water level in the Veeranam lake in Cuddalore district, a prime water source for Chennai, is brimming over. Anxious to protect the embankment and prevent vast acres of crops in the tail-end of the delta region going under sheets of water, officials have decided to maintain the water level in the lake at 43.5 feet as against its full capacity of 47.5 feet.

The water level in the lake as on Tuesday stood at 43.7 feet. The inflow was 1,000 cusecs while the outflow was maintained at 1,474 cusecs. Water supply to Chennai from the lake for drinking water needs resumed a month ago and on Tuesday 73 cusecs of water was released to Chennai.

With the discharge of water from the lake, the crops on about 10,000 acres in Kattumannarkoil and Chidambaram have been submerged. The officials were of the view that the heavy rains had not damaged the crops yet but admitted that if the spell continued for another two days, the situation could turn bad.

Paddy was raised in 90% of the tail-end delta regions. "The next 48 hours is very crucial for the farmers in these regions. If rain continues, the loss of crops will be enormous and if not, there are possibilities of stagnant water draining out quickly. Majority of the crops submerged were raised a month ago and damage would be less in these areas," said Veeranam Pasana Vivasayeegal Sangam president KV Elankeeran.

But rains wrecked havoc to the betel leaves cultivated in about 3,000 to 5,000 acres of plantations near the lake including in places like Thiruchinnapuram, Nanthimangalam, Lalpettai and Elleri. "Betel leaves are water-intensive crops and are generally raised in regions near the lake. The crops raised in about 3,000 to 5,000 acres of land have submerged under water for the past one week and are completely damaged," Elankeeran said.

Cuddalore collector P Seetharaman while briefing reporters said the district administration submitted a proposal for Rs 23 crore to the state government for strengthening the banks of Veeranam Lake.

Detailing the preparedness of the district administration in tackling the north-east monsoon, the collector said the project will be taken up shortly. The project includes de-silting 28 supply channels of the lake at a cost of Rs 12.56 crore renovating the existing shutters at a cost of Rs 1.26 crore and erecting new shutters at Rs 46 lakh.

He revealed that a new bridge at a cost of Rs four crore connecting Nanthimangalam and Poolanmedu in Kattumannarkoil taluk will be constructed, another new bridge at a cost of Rs 1.5 crore connecting Nanamedu and Uppalavadu and a new regulator at a cost of Rs six crore will be erected at VNS anicut.

"Crops cultivated in about 20,500 acres of land have been submerged under water, but the incessant rain has not damaged the crops," he claimed.

Four persons and four cattle have been killed in rain-related accidents. Thirty-two houses were completely damaged and 135 houses partially damaged.

Veeranam project will avert flooding

New project will avert flooding - The Hindu

CUDDALORE: The New Veeranam Project, estimated to cost Rs.23 crore, has been drafted to ensure the stability of the Veeranam tank and also to avert flooding in the ayacut areas, according to P.Seetharaman, District Collector.

Addressing a press conference here today on the preparedness of the administration to tackle the cyclone and flood situation in district the Collector said that the new project envisaged repairing and replacing of the damaged sluices, reinforcing the bunds, and, clearing the inlet and outlet channels of the outgrowths and other encroachments.

Based on deliberations with the stakeholders on the safety of the tank it had been decided to maintain the water level at 43.9 ft (maximum 47.5 ft). Therefore, the entire inflow of 3000 cusecs of water, realized through the Sengal Odai and the Karuvatti Odai, was being discharged.

However, to prevent flooding in the downstream the outflow through the Velliyangal Odai had been reduced from 500 cusecs to 250 cusecs to allay the fears of the ayacutdars about the possible inundation of the crops. Moreover, a portion of the excesses too was being drained in the Vellar.

A canal for a length of 5.5 km had been dug up to safely carry the water pumped out from the Neyveli Lignite Corporation mines. Earlier, the Paravanar fed by the water from the mines used to breach its course and inflict heavy damage to the standing crops.

The Collector also stated that of the 296 water sources in the district 198 were filled to the brim. In 50,000 hectares under samba crops the transplantation process was completed in 45,000 ha but if the rain continued the seedlings would perish. Water hyacinth choking the waterways in Chidambaram block were being removed.

According to a preliminary estimate about 57 villages in the district—21 in Cuddalore, 13 in Kattumannarkoil, 12 in Chidambaram, five in Vriddhachalam and three in Panruti– were facing the threat of inundation.

Cyclone shelters

Mr.Seetharaman observed that all the 21 cyclone shelters—13 in Chidambaram block and eight in Cuddalore block—had been kept in readiness to accommodate those who might get displaced by natural disasters.

A buffer stock of 818 tonnes of rice was kept ready (stored in at least 237 fair price shops in the vulnerable areas) to feed the people during exigency.

Rescue boats and fire service personnel had been on the alert to evict the people from the areas likely to be affected by flood.

An infantry battalion had been kept ready in the Secundarabad barracks and whenever warranted they would move in, the Collector added.
