The 275 MW Kopili Hydropower Dam of NEEPCO (a Union Power Ministry organisation, now under NTPC) has again faced a major disaster on Saturday, March 26, 2022. Earlier, the same project had suffered disaster in October 2019.[i]
The penstock pipe that takes water at high flow rates and speed from the Umrangso dam to the hydropower house burst during early hours of Saturday in Assam’s Dima Hasao (earlier called North Cachar Hill) district. A large portion of the Kopili Hydro Electric Plant was also inundated.[ii] At least three employees of the North Eastern Electric Power Corporation Limited (NEEPCO) who were present at the site were killed in the mishap.

After Pulichintala dam gate disaster[i] of August 05, 2021, the state of Andhra Pradesh has witnessed another dam induced flood disaster in 2021. This started with, part of Annamayya dam in Pennar (also called Penna) river basin[ii] getting washed away resulting in widespread destruction in downstream areas on November 19.
Around same time, there were more incidents of damages to dams and dam induced flooding in Kadapa, Chittoor, Anantapur districts of Rayalaseema and adjoining Nellore district. Firstly, the collapse of Pincha project ring bund contributed to Annamayya flood disaster. Then, one of metal bund of Mylavaram project was washed away.
Fourthly, the sudden releases from Veligallu and Buggavanka dams in Kadapa and Kalyani dam in Tirupati resulted in flash flood destruction in downstream areas. Apart from this, the leakages in Rayalacheruvu tank bund in Chittoor district could have turned into a big disaster.

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.

The suggestion of a robust early warning system always echoes as and when there is a disaster in the Himalaya. Hence, the murmuring of having a state of art early warning system after the February 7th 2021 Rishi Ganga disaster is nothing new.
Several concerned scientists of the country are considering of instituting a new centre using the state of art remote sensing techniques. The centre would be dedicated to the early warning forecasting in the Himalayan region. This is heard practically after every disaster since last two decades.

Abstract: While Uttarakhand is vulnerable to disasters, climate change is increasing these vulnerabilities. Major human interventions like hydropower projects and highways implemented without an informed or democratic decision-making process act as force multipliers during such disasters. The violations of legal and other prudent norms in their implementation further increase the damages. The absence of necessary monitoring, early warning systems and the overall disaster management system add another layer of damages during the disasters. The lack of the ability to learn lessons from disasters and lack of any accountability ensures the perpetuation of the situation.

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].
