Andhra Pradesh: Pulichintala Dam Gate disaster shows improper maintenance and operation

In another dam related disaster in Andhra Pradesh, a flood gate of K L Rao multi-purpose irrigation project also known as Pulichintala  Dam was washed away on August 5, 2021 raising flood alarm in downstream areas along Krishna river. As per latest information the gate has been fixed and officials have started filling up the reservoir again. However, there is no official statement regarding exact causes, financial losses, damages to dam structure and downstream flood impact caused by the apparently avoidable dam disaster. The rule curve seems to be violated in operation of every dam and the gates do not seem to have been properly maintained. An independent enquiry needs to be immediately set up to find out what lessons we can learn and how we can fix accountability for the disaster.

Durgapur Barrage on Damodar Damaged again: Its Dam Safety under World Bank-AIIB projects

Late on Friday (Oct 30 ,2020) night the gate no 31 of the Durgapur barrage suffered heavy damage, leading to emptying of the barrage and major disruption of the domestic, industrial and irrigation water supply. Shockingly, the Dam Safety aspects of the 65-year-old barrage on the border of Bankura-W Bardhaman districts of West Bengal[i] on Damodar river is under the World Bank and AIIB funded projects. This episode again[ii] puts a big question mark over credibility of the World Bank’s performance on dam safety issues in India, just a day after the Cabinet Committee on Economic Affairs headed by the Prime Minister cleared massive Rs 10211 Cr WB funded dam safety project[iii].

A tale of two dam breaches: Spencer (USA) and Tiware (India)

On March 14, 2019 the Spencer dam on Niobrara river, located south of Spencer in Nebraska state in USA breached, killing four people in the downstream. The Investigation Report about the disaster has been made public now on April 24, 2020. The remains of Spencer Dam — a skeleton of concrete and steel amid a sea of sand — became one of the iconic images of the March 2019 “bomb cyclone” flood that caused billions of dollars in damage across Nebraska.

Less than four months later, on July 2, 2019, Tiware dam breached[i] in Chiplun taluka of Ratnagiri district of Maharashtra, killing 23 people. The then Maharashtra Chief Minister Devendra Fadnavis on July 6, 2019 announced a Special Investigation Team (SIT) to probe into the disaster, the SIT was to submit a report in two months, but the report was submitted in January 2020, but the report is not in public domain. When SANDRP talked with the chairman of the committee, he disclosed that the report has been submitted to the department in early Feb 2020 and it can only be made public by the department once they accept the report. He revealed that the SIT had found that there were issues with material of construction (masonry in place of Concrete) and design of the conduit of the dam. He agreed that the report should be made public promptly, but expressed his helplessness in face of the norms in India. SANDRP also called Secretary, Department of Water Conservation, Govt of Maharashtra, but got no response.

There is a lot to learn for us in India in comparing the two dam breach incidents and how both are treated.

DRP NB 25 Nov. 2019: Cauvery is calling, but do we understand her message?

Interrogating Cauvery Calling N Ram questions Jaggi Vasudev’s Cauvery Calling, asks why it shifts goal posts Speaking at Interrogating Cauvery Calling seminar in Chennai, N Ram said that various state governments and the central government that endorses the project should also be questioned.

 “Now a very serious issue that must cause concern is the raising of public interest and public money for this project. Truly mega, in terms of money involved – 242 crore trees, 11,000 crore rupees. That is the kind of money involved. Only 0.5% collected. There is still time to put checks on this and prevent this from going further,” he said. “What is the management of this money? Who oversees it? There is no transparency, no verifiable document, no clear management structure for huge amount targeted. It is a matter of great concern.”

– N Ram also said that various state governments and the central government that endorses the project should also be questioned. “As a political journalist, this is the question that occurs to me. Who gave the Isha Foundation the right, the jurisdiction to transgress on what should be the commons. And why are governments being subservient to this idea? Apart from the risks, probable negative outcomes and over simplification of solutions for Cauvery, this is what is worrying,” he concluded.  https://www.thenewsminute.com/article/n-ram-questions-jaggi-vasudevs-cauvery-calling-asks-why-it-shifts-goal-posts-112838  (24 Nov. 2019)

DRP News Bulletin 27 August 2018: WRONG Management of DAMS Create FLOODS, Accept Officials and Experts

Accepting that reservoirs operation and flood management in India lack scientific supports, Madhavan Nair Rajeevan, Secretary, Ministry of Earth Sciences, in an interview has revealed that dams and water reservoirs need flood management systems that use scientific methods to understand when the time is right to open the gates.

“As per my understanding, no big reservoir has a decision support system. So we don’t know when to open them, how to open them… I am not attributing the Kerala floods to an individual. There is a common perception that in India most of the flood management systems are not supported by science… I am very sure we don’t have the decision support system and we need it.” https://indianexpress.com/article/india/not-just-kerala-no-scientific-dam-water-management-across-india-madhavan-nair-rajeevan-secy-earth-sciences-5322003/  (24 Aug. 2018)

In another interview he says that while Kerala records among the highest amounts of rainfall in the country, the State did not have a flood warning system in place. He added that while there were several sophisticated tools to anticipate extreme weather events, India still lacked a mechanism to effectively deploy them. https://www.thehindu.com/sci-tech/energy-and-environment/reservoirs-not-managed-using-a-scientific-decision-support-system-m-rajeevan/article24785253.ece  (26 Aug. 2018)

Further in a detailed interview, he pitches for ‘decision support systems’ at dams, acknowledges the challenge of climate change, warn against repercussions of ‘fast-warming’ Indian Ocean. https://indianexpress.com/article/india/kerala-floods-m-rajeevan-ministry-of-earth-sciences-met-department-5324840/  (26 Aug. 2018)

Idukki Dam releases water when Kerala is in Floods: Could this have been avoided?

Kerala is facing serious floods. Army, Navy, NDRF, neighbouring states are all out. Dozens of people have died, landslides happening, houses washed away, the whole machinery is out to deal with the crisis.

In this flood crisis, Idukki & Idamalayar two of the Kerala’s biggest dams along with about two dozen others, are releasing water, adding to the floods and the disaster. Why are Idukki and Idamalayar, both having live storage capacity above a Billion Cubic Meters, releasing water NOW, when whole of Kerala is facing floods due to recent excessive rains? Standard excuse: The dams are full and they have no option but to release the water, they cannot store more. But why did they wait to start releasing water till the dams are full and they are faced with TINA: There is No Alternative. This love to be in TINA situation seems like a disease affecting all dam operators.

DRP News Bulletin 30 July 2018: Laos Dam DISASTER: Yet Another Wake Up Call?

The various aspects of tragic Dam Disaster in Mekong Basin in Laos are still unfolding. But it is clear from many accounts that it was an avoidable, man-made disaster due to neglect of contractors, decision makers, consultants and supervising agencies. There is a lot we can learn from this if we want to avoid such disasters in India. We still do not have credible Dam Safety Law or institution, CWC is clearly not the right agency considering the conflict of interest with the various other roles of CWC. But for now let us look at the reports of Laos Dam Disaster.

Reminding the world of one of the worst dam disasters, the under construction dam Xepian Xe Nam Noy Hydro power project breached releasing 5 billion cubic metres of water in Southern Laos on July 23.

The gushing water current swept the surrounding leading to death of about 26 people and displacing about 6600 residents. As per report hundreds of people are still missing from neighbouring villages of Yai Thae, Hinlad, Mai, Thasengchan, Tha Hin, and Samong, which bore the brunt of flooding. The deluge has reportedly destroyed thousands of homes.

How India Measures Water Storages

Govt and media typically report the status of water storage in India using the CWC’s Weekly Reservoir Storage Bulletin, which contain information about just 91 reservoirs in India. In this article we show that the state websites provide information about huge 3863 reservoirs, which even if not sufficient, is a huge improvement over just 91 reservoirs that CWC bulletin includes. We hope all concerned will try to improve the reservoir storage reporting.

It should be added here that this measures only surface water stored in some of the large reservoirs of India. This excludes large number of big reservoirs, lakhs of smaller reservoirs, groundwater aquifers and soil moisture storage. In spite of these limitations, this provides more accurate picture than just the 91 reservoirs of CWC that everyone in India, including media, govt monitoring and policy makers look at.
