DRP News Bulletin 17 December 2018: Dam Safety Bill Introduced, Tamil Nadu, Odisha Oppose; Why No Role For Independent Experts?

On Dec 12, 2018, The government introduced the Dam Safety Bill amid din in the Lok Sabha on Wednesday even as Biju Janata Dal group leader Bhartruhari Mahtab questioned the legislative competence of the House on the matter.

The Bill provides for “surveillance, inspection, operation and maintenance of specified dams for prevention of dam failure related disasters and to provide for institutional mechanism to ensure their safe functioning”. There are over 5,200 large dams in the country and about 450 are under construction. There are also thousands of medium and small dams whose safety remains a matter of concern due to lack of legal and institutional safeguards. https://indianexpress.com/article/cities/delhi/parliament-winter-session-govt-introduces-dam-safety-bill-5490911/   (13Dec.2018) Continue reading “DRP News Bulletin 17 December 2018: Dam Safety Bill Introduced, Tamil Nadu, Odisha Oppose; Why No Role For Independent Experts?”

DRP News Bulletin 10 Dec. 2018: Yamuna Pollution; Will NGT Panel Make Any Difference?

In its latest report, the National Green Tribunal (NGT) appointed monitoring committee overseeing Yamuna River cleaning progress in Delhi says that the river is “fighting to stay alive” and it would not be possible to rejuvenate the Yamuna unless minimum environmental flow is provided as it is “virtually reduced to a trickle and remains dry in some stretches for almost nine months of the year”.

In the action plan, it is mentioned that “Although the Yamuna river flows only for 54 kilometres from Palla to Badarpur through Delhi, the 22 km stretch from Wazirabad to Okhla, which is less than 2 per cent of the river length of 1370 km from Yamunotri to Allahabad, accounts for about 76 per cent of the pollution level in the river”.

The committee has suggested that a team of scientists be formed from CPCB, DPCC and other institutions like IIT Delhi or NEERI to carry out inspections and submit reports to it for remedial action. The team can look into the risks and benefits of an alternative way of routing the same quantity of water which can help in reducing the pollution level, it said.

The monitoring committee also raised objection to the capacity utilisation of common effluent treatment plant (CETP) which is as low as 25 per cent. There are 28 industrial clusters in Delhi and 17 of these are connected to 13 CETPs. The remaining 11 clusters are not connected to any CETP. Another area of concern is the direct discharge of completely unregulated waste from industries and residences into the river.

Dam Floods 2018: Assam, Himachal; Making Dam Operators Accountable

ASSAM: NEEPCO a repeat offender? On July 27, 2018 sudden release of water from NEEPCO’s Doyang Hydropower Electric Project (HEP), located in Wokha district, Nagaland led to flood disaster[1], submerging[2] about 36 villages in Golaghat a district in Upper Assam. According to Rony Rajkumar, project officer of the Golaghat district disaster management authority, around 5,575 people were affected by the deluge which damaged 887.9 ha of crop.

Earlier, on July 11, 2018, reviewing the severe flood situation Lakhimpur Assam, the Chief Minister (CM) Sarbananda Sonowal strongly warned[3] the state-owned power utility NEEPCO not to release water from its Ranganadi dam without warning like previous years.

Kerala: Dams Floods 2018: Follow Rule Curves to Avoid Flood Disasters

Unprecedented Kerala deluge[1] that swept through the coastal state on the day of Independence day 2018 was most disastrous flood incident in the year. It has also been termed as one the worst flood in the state and reminded the people of July 1924 and July 1962 flood calamities. Many experts, several reports and studies have established the role of dams in worsening the deluge. According to reports, 35 out of the 46 dams within the state were opened for the first time in history[2]. All 5 overflow gates of the Idukki Dam were opened at the same time, for the first time in 26 years.

State Government Accepts Dams Role

Kerala is usually considered a flood-proofed[3] state with its undulating terrain. For a state that receives an annual average rainfall of nearly 3,000 mm, its natural landscape protects it from recurrent floods. Indeed, the Kerala flood has highlighted our poor dam management[4] system. 

As per officials the crisis could have been contained[5] had the state “gradually released” water from at least 30 dams, in advance of high rainfall, adding that local authorities failed to foresee the imminent danger with high rain predictions. “Such floods have probably recurred after 100 years, exposing the State’s unprofessionally run reservoirs management system and unpreparedness on disaster mitigation and disaster resilience.

DRP News Bulletin 15 October 2018: Reuters Corroborates that Dams Played Major Role in Kerala Floods

International news agency, after independent research, have corroborated what SANDRP has been saying: Mismanagement of dams played big role in worsening Kerala floods.

-“The release could have started earlier so that by Aug. 9 there would have been left-over capacities in the reservoirs to store the water,” said Biswajit Mukhopadhyay, director of water resources at U.S-based engineering firm IEA, who analysed some of the publicly available data at the request of Reuters.

– Still, dozens of flood victims interviewed by Reuters, who live in villages dotting the banks of Kerala’s biggest river, the ‎244 km Periyar, say they faced no floods despite torrential rain in late July and early August. All of them said waters only rose overnight on Aug. 15. That was when more intense rainfall forced KSEB to rapidly ramp-up releases of water from Idukki and Idamalayar reservoirs, which feed into the Periyar.

– Kerala’s revenue secretary and head of disaster management, P.H. Kurien, told Reuters he has twice written to KSEB requesting EAPs and has yet to receive them. KSEB’s Pillai said EAPs and dam operation manuals were still being prepared. CWC said it was working with Kerala’s government to speed this up. The Kerala Chief Minister’s office did not respond to requests for comment. https://widerimage.reuters.com/story/did-dams-make-indias-once-in-century-floods-worse  (11 Oct. 2018)

CWC Flood Forecasting: Anomalies between Website and SOP Document

Central Water Commission (CWC) is the only agency in India doing flood forecasting, it becomes very important to understand what CWC does in this regard. The CWC flood forecasting website[i] is the main media through which CWC provides the flood forecasting. CWC has also published on its website, the document giving Standard Operating Procedure (SOP) for flood forecasting in 2018[ii]. The Home page of the CWC’s flood forecasting site says that CWC provides Level forecasting for 166 sites and Inflow forecasting for 60 sites. SOP document, however, gives these figures in Table 1, but in Table 2 (as also the full list given in Annexure 1.1 of SOP document), it gives state wise break up for 182 Level forecasting and 93 Inflow forecasting sites. So we can see anomalies in these two sources even about the number of forecasting sites.
