DRP 14×24: Big Dams, Long distance water will not solve Urban Water Crisis

October 14, 2024February 27, 2026 SANDRPLeave a comment

In a pointed article this week, Sachin Tiwale rightly writes that Mumbai does not need more dams, but needs to fix the distribution of more than enough water that it gets currently. Same is the case with highly capital and energy intensive 5^th stage of Cauvery Water Supply being inaugurated on Oct 16 by the Karnataka Chief Minister and Deputy CM for Bangalore, advertised through full page advertisements today (Oct 14) in newspapers in Bangalore.

What the India’s cities need is to exhaust the potential of local water resources, including rain water, local water bodies including rivers, groundwater recharge, recycle and reuse of treated sewage and also demand side measures, including fixing the distribution and reducing transmission and distribution losses. All of this needs attention through a National Urban Water Policy that will also fix the Urban Water Governance.

DRP 300924: Focus on River Studies

September 30, 2024February 27, 2026 SANDRPLeave a comment

Rivers are the most important ecosystems (eco here includes ecology and economy) and yet possibly least studied entities. Some news below this week about some river studies brings the focus on need to take up many more river related studies.

Most important aspect of river related studies is the need for credible, independent studies, not influenced by the needs of the governments. Otherwise, the government is likely to not only influence the study, but also decide not to make it public as they did in case of the studies related to Joshimath town and role of Chamoli disaster.

Amid the unprecedented flood spell in Krishna river passing through the Prakasam barrage located in Vijaywada city of NTR district in Andhra Pradesh, an incident of ‘sand boats’ getting stuck and damaging the barrage in early morning of Sep. 2, 2024, has been reported. The number of boats varied from three to five. The incident became a cause of worry for the structural safety of the barrage.

The New Indian Express report mentioned above reported, quoting irrigation officials that all 70 gates of the barrage were lifted at 2200 hours on Sept. 2, 2024, passing 11.03 lakhs cusecs of water, highest in 70 year history of the barrage. The report stated: “Previously, the Krishna River saw historic floods from October 2 to 13, 2009, when the maximum inflow recorded at Prakasam Barrage was 11,10,404 cusecs at 11 pm on October 5.”

Dam Disaster

Tungabhadra Dam: A Crest Gate washed away in August 2024

August 11, 2024September 6, 2024 SANDRP3 Comments

In a major dam related disaster at around 10.50 pm on Aug 10, 2024 [i], one of the crest gates at the Tungabhadra dam has broken [ii] near Hospete in Vijayanagara district in Karnataka, causing the release of 70,000 to 100,000 cusecs of stored water. The chain on the 19^th (of total 33 gates) gate of Tungabhadra dam on Tungabhadra river, part of Krishna River Basin, got cut, snapped and was washed away about 100 m from the dam on Saturday. The chain that was used to operate the gate snapped as the welding gave way. The Tungabhadra gates only have chain and not chain and rope as in some other dams. The force of the water in the dam swept the 60-foot-by-20-foot gate, weighing around 20 tonnes, some 500 ft away, J Purushottham, president of the Tungabhadra Farmers’Association, said. This possibly happened due to heavy flows, but also due to wear and tear of over 70 years of operation of the dam. A temporary stop log gate is now being planned, as permanent crest gate will take time.

The disaster raises a number of questions about the operation and maintenance of the dam.

DRP 131123: Another Himalayan Disaster: 40 workers trapped in a tunnel in Uttarakhand

November 13, 2023February 27, 2026 SANDRPLeave a comment

In yet another disaster in the Himalayas, at least 40 workers are trapped in an under-construction tunnel being constructed by National Highways & Infrastructure Development Corporation Ltd. (NHIDCL), among others. The Hindustan Times has wrongly named the construction company as Hydroelectricity Investment & Development Company Limited (HIDCL) possibly of Nepal govt. Some people at the location have informed us that it may take another day before the workers are rescued.

NHIDCL was not even sure of the total of number of workers, as they gave the number as 36, which was corrected by the district administration later on to 40. It is also strange to see the work going on even on a Diwali day. Another disturbing aspect is that all the workers are reportedly mostly from outside Uttarakhand, when Uttarakhand villagers are known to migrate in large numbers to outside the state for employment. This disaster thus raises a lot of questions, which will need answers once the workers are rescued safely. The workers are still trapped over 30 hours after the disaster. The work at the 4.5 km long tunnel is being built under Char Dham Road Widening project since over 4 years, and violations have been happening in the work since then, as we reported in 2019.

Massive Landslide AGAIN damages Lower Subansiri Hydro Project in Oct 2023

October 28, 2023November 8, 2023 SANDRPLeave a comment

Once again, after several such incidents in the past, the controversial 2000 MW Lower Subansiri Hydropower project on Assam Arunachal Border was hit by a massive landslide at around 11.30 am on Oct 27 2023. The landslide damaged the project, further delaying the commissioning of the first unit, increasing the cost and time over runs of the expensive, much delayed project. Following the landslide, the only functioning diversion tunnel no 1 of the project, about 200 m upstream from the dam was blocked. The river water, about 997 cumecs (cubic meters per second) suddenly started flowing towards the dam, where the spillway gates were still under installation, yet to be tested. The water could overflow from the under construction spillway gates once the reservoir reached 145 meters level (above Mean Sea Level). The massive, majestic Subansiri river was completely without any flow till the river water started flowing through the spillway gates about twelve hours later. (Feature photo above shows the snapshot when landslide started and in the foreground, water is seen rushing towards the dam)

Assam Rajya Sabha MP Ajeet Bhuyan, referring to the October 27 landslide said in his letter to Prime Minister that the incident is only a warning, which can’t be ignored: “The hilly soil of Arunachal is fragile. Secondly, the dam site is earthquake-prone. Thirdly, the base of the dam was reduced by 09 metres without any public explanation. These are enough indications for a major disaster in the coming days”. On Oct 31 2023, he appealed to PM to take swift measures and fix accountability. He reminded PM that Mr Modi himself had said in 2014 no big dams in North East if people do not want. He also reminded that current Defense Minister Rajnath Singh had also said they will scrap the project. Mr Bhuyan said that he apprehended much bigger disaster than recent Sikkim Disaster if this projects goes ahead.
