Chennai: Poondi reservoir starts receiving Krishna water

CHENNAI: The Poondi reservoir has started receiving Krishna water, discharged from the Kandaleru reservoir, from Monday evening, officials of the Water Resources Department here said.

According to them, about 200 cubic feet per second (cusecs) was realised at the Poondi reservoir by 6 a.m. on Tuesday. (One cusec of water is equal to 28.3 litres). As the discharge from the Kandaleru reservoir has been stepped up to 1,900 cusecs, the Poondi reservoir is expected to receive about 800 cusecs by Thursday.

“We have asked for the release of water to continue till April for augmenting the city supply,” said an official. This is the second time that Chennai is being supplied with Krishna water in 2009-10. The city had realised 4.1 thousand million cubic feet (tmcft) from the Kandaleru reservoir between September and December 2009.

Since 2006, Chennai has been getting around six tmcft of water every year. Uthukottai, the inter-State border of the Kandaleru Poondi canal got 6.9 tmcft of water in 2008-09, which was the highest quantum received since the commissioning of the Krishna Water Supply project a decade ago.

“If we get two or three tmcft during this spell, it will be sufficient to cater to the city’s water needs till the onset of the northeast monsoon,” an official said.

The cumulative storage of the four reservoirs that cater for Chennai — Poondi, Cholavaram, Red Hills and Chembarambakkam — stood at 6.7 tmcft against its capacity of 11 tmcft on Tuesday.

Bangalore: Vision document on irrigation by next week

BANGALORE: A vision statement on the irrigation projects to be taken on a priority basis over the next decade is being brought out by the State Water Resources Department. Also, irrigation projects are being subject to scrutiny on quality parameters.

Water Resources Minister Basavaraj Bommai on Monday said that the vision document will be released in about a week.

The Quality Assurance Cell to be specially constituted will comprise experts from Indian Institute of Science (IISc) and Indian Institute of Management, Bangalore (IIMB).

The estimate of the money required for the pending irrigation projects in the Krishna and Cauvery basis stands at Rs 45,000 crore.

The specific aspects of implementation and the expected expenditure on each of the projects will be detailed in the statement, Bommai said.

On quality assurance the minister said that electronic meters are being used in projects in the Ghataprabha basin.

On an experimental basis, electronic metering is already undertaken on the Ghataprabha main canal and its distributaries, Bommai said and noted that Malaysia is among the countries which has successfully implemented the electronic metering scheme in irrigation projects.

These electronic meters can send: about 120 SMSes per second; details on the quality and availability of water at a various points along the route may be gathered at one go, he explained.

Meanwhile, the minister said that much of the cultivable land in the state will be irrigated by June.

About 1.25 lakh acres were irrigated last year: 55,000 acres in the Upper Tunga belt, 12,000 acres in the Cauvery basin and the rest in Krishna – Godavari belt, he explained.

Chennai: Krishna water supply resumes

Inter-State border to realise water today

900 cusecs discharged from Kandaleru reservoir into the canal around 6 p.m.

500 cusecs already being released into canal for Tirupati, Srikalahasti

CHENNAI: After a gap of over a month, Krishna water supply to Chennai resumed on Saturday.

This follows the recent visit by a team of officials from the Water Resources Department to Andhra Pradesh.

Nearly 900 cubic feet per second (cusecs) was discharged from the Kandaleru reservoir into the canal around 6 p.m.

As the canal bed was wet, Uthukottai, the inter-State border in Tamil Nadu, would realise water quicker without much seepage by Sunday. From there, water has to travel another 25 km to reach Poondi reservoir, the storage point.

According to WRD officials, 500 cusecs was already being released into the Kandaleru-Poondi canal for supply to Tirupati and Srikalahasti.

The discharge was stepped up by another 400 cusecs to cater to Chennai’s water needs.

“The authorities concerned in the neighbouring State have assured us that the water release will be increased by 300 cusecs on Sunday,” an official said.

The supply was disrupted in mid-December due to the turmoil over the Telangana issue and maintenance work of canal.

The city had received 4.1 tmcft of Krishna water between September and December last year.

Krishna water supply was much-awaited in the wake of depleting resources at the four city reservoirs in Poondi, Red Hills, Cholavaram and Chembarambakkam. The combined storage of the reservoirs stood at 6,866 million cubic feet (mcft) against their full capacity of 11,057 mcft.

The reservoirs had storage of 9,025 mcft during the same period last year.

Bangalore: Govt plans new irrigation tanks in Krishna basin

BANGALORE: The government proposes to construct at least 500 new minor irrigation tanks in the River Krishna basin, Minister for Minor Irrigation Govind Karjol said on Friday.  

Speaking to reporters, he said that the envisaged number includes tanks and barrages. The department has appealed for a budgetary allocation of Rs 1,000 crore for the same. The total cost estimate is about Rs 4,000 crore, he said.  

Of the Rs 57 crore that was allotted for the purpose in 2009-10, Rs 46 core had been released, he said. Karjol noted that there was no scope for construction of new tanks in the Cauvery basin as the state had exhausted its allocated share.  

Identification of tank bed encroachments and steps to clear them were on across the state and in the jurisdiction of urban local bodies like City Corporations, he said. The department has reiterated its stand that local bodies should take responsibility for its water bodies, Karjol said

Andrapradesh: 8,000 sq-km submerged in a day

Vijaywada, Oct. 6 — The furious river waters sheared for days through farmland and homes, inundating 20 lakh acres every day – Delhi five times over, or 13 cities the size of Mumbai. The Krishna rushed in from the Almatti dam in Karnataka and submerged 8,000 sq-km of land in a day. It now stands at the gates of the British colonial-era Prakasam Barrage in Andhra Pradesh next door, and a breach here could submerge vast swathes in the state’s rice-rich Krishna and Guntur districts.

The Prakasam barrage is a key passageway for the Krishna, which meanders through Karnataka and Andhra Pradesh on way to the Bay of Bengal. On Tuesday, hundreds jostled here despite restrictions. Nearby, on a hillock, is the Kanaka Durga temple. People here believe that the day the idol is submerged, the entire city of Vijaywada will be washed away. If it does, it would be blamed on tardy cooperation between the two states. Until Saturday night, Andhra Pradesh did not evacuate people from the catchment of the Nagarjunasagar Dam as the Karnataka government assured that no more water would be released from its Srisalam dam. But as floodwaters poured in, gates were opened at Srisalam, worsening the situation.

“There appeared to be a breakdown of communication between the two neighbouring states,” said a senior official of the National Disaster Management Authoritry (NDMA), speaking on condition of anonymity due to the sensitivity of the subject. But technology might soon make up for government delays. NDMA member NVC Menon said that by 2012, people would be alerted about rising water within minutes of it being tracked by satellites.

Sloth after natural disasters is a annual story in India, a flood prone nation where tackling flooding comes under the states’ domain and New Delhi’s financial assistance since 2007 of Rs 8,000 crore (Rs 80 billion) has shown few results. Then, there is the lack of accountability.

“In the last 60 years, not a single engineer has ever been charged or punished for mismanagement of these dams,” he said.

Chennai: Water levels dips in reservoirs

CHENNAI: While the neighbouring states of Karnataka and Andhra Pradesh Have been battered by rains and floods, Tamil Nadu has a different story to tell. The state hasn’t received enough rain this year and, in Chennai, an aggregate of the levels in the four reservoirs that supply water to the city shows that they are cumulatively down by 1,246 Million Cubic Feet (MCFT), compared to the same period last year. However, officials of the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) state that there is sufficient water for the city till December and beyond.

The total capacity of the four reservoirs (Poondi, Red Hills, Cholavaram, Chembarambakkam) that supply water to the city is 11,057 MCFT. Against this, the current levels account for 2,731 MCFT, 1,246 MCFT less than last year’s 3,977 MCFT.

While in Poondi, the total capacity is 3,231 MCFT, the storage position on Tuesday indicated 797 MCFT. In Cholavaram, storage was 188 MCFT, as against the total capacity of 881 MCFT. In Red Hills, against the total storage capacity of 3,300 MCFT, the water level was 1,294 MCFT. In Chembarambakkam, the water level recorded was 452 MCFT; the total capacity is 3,645 MCFT.

The total rainfall recorded in Poondi, Red Hills and Cholavaram this year so far is 404 mm, the highest being 146 mm in August 2009. “The main reason for the decline in storage levels is the delay in getting supply from the Veeranam Lake and water from the Krishna. Lack of sufficient rainfall also adds to the problem,” said a senior Metrowater official.

CMWSSB did not receive Veeranam water supply between May and August this year. Later, once water began flowing in, CMWSSB began drawing 180 Million Litres Per Day (MLD) from Veeranam and supplying to the city. Krishna water, supposed to reach Tamil Nadu in July, was delayed and arrived only in September. Currently, 800 MCFT is flowing into Poondi.

“Some weeks ago, the storage position in Poondi was only 5% of its total capacity. Ever since the Krishna water started arriving, it increased to 25%. The level in Poondi is increasing with continuous supply. Once the storage level increases, we will release the water into the Chembarambakkam reservoir, then into Red Hills and later for city supply,” said the official.

The official said that with the northeast monsoon expected soon, the water position would be better. “With the current position we can manage till December and beyond. There will not be any shortage of water,” said the official.

Flood water reaches Prakasam barrage, AP villages face threat

Vijayawada, Oct 5 (PTI) River Krishna virtually turned into a sea in all its fury today as a record 10.61 lakh cusecs of flood water reached Prakasam Barrage, threatening to submerge some villages.

This is the heaviest flood in river Krishna in more than 106 years as the previous record stands at 10.30 lakh cusecs in 1903, irrigation authorities said.

The water level touched 21.4 feet at Prakasam Barrage and all the 72 sluice gates have been lifted to let out water into Bay of Bengal.

They said said the current flood discharge at Nagarjuna Sagar has been reduced to 10.3 lakh cusescs from 11 lakh cusecs yesterday.

The discharge is expected to remain constant at least in the next 24 hours and the outflow from Prakasam Barrage will also be around 10.5 lakh cusecs.
