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.

Maharashtra State’s groundwater surveys and development agency (GSDA) has warned of a water scarcity in 11,487 villages of 167 tehsils in the State. In its 2018-19 report, the GSDA, which comes under the department of water supply and sanitation, has said the study of the groundwater level (in comparison to the level in October in the last five years) has shown that of the 353 tehsils in the State, 13,984 villages in 252 tehsils have shown a decrease by more than one metre.

Between October 15 and 21, 380 tankers were used across the State, against 91 tankers in the corresponding period last year. A week prior to that the number was 354, and 329 tankers were used in the first week of October.

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.

DRP News Bulletin 1 October 2018: Hungry Water Effect due to Dams & Unsustainable Sand Mining Worsened Kerala Floods

Dams and reservoirs make rivers sediment-starved and menacing manifold downstream. While heavy rainfall is also a key factor behind the floods, hungry water had a more pronounced effect, says D. Padmalal, Scientist and Head, Hydrological process group, National Centre for Earth Science Studies.

– “When the sediment transport is interrupted, the potential energy of the hungry water released from dams will scour the river banks downstream, uprooting trees or riparian vegetation and damaging bridges and other engineering structures,” explains Dr. Padmalal. Overloaded with silt and clay from the eroding river banks, the highly turbid and viscous water clogs drainage channels. Subsequent discharge of water from the dam will lead to inundation and waterlogging of large areas.

– Hungry water can also develop in high gradient river channels devoid of adequate quantity of sand and gravel, especially during periods of high rainfall. “Years of uncontrolled sand mining have left most of the rivers in Kerala depleted or exhausted of sand and gravel. This creates a situation similar to the release of hungry water from dams,” notes Dr. Padmalal. When the river channel has adequate supply of sand and gravel, the potential energy of the water is used to transport the mixture. The water does not scour the banks or turn muddy.

DRP News Bulletin 24 September 2018: If NGT Can’t Provide Environment Justice…

Unless immediate corrective action is taken, the NGT which has till recently served as an institution to provide environmental justice, will increasingly become an institution to perpetuate environmental injustice. If this is to happen, it will be a sad day for both India’s environment and democracy; writes Ritwick Dutta.

– Last few months have seen a massive decline in public confidence in the NGT. The first wake-up call was in July when the new chairperson of the NGT commented that around 50% of the petitions before the tribunal were filed by “blackmailers”. Nothing could be more distressing because this comes from an institution that was created to protect the rights of the people. Recently, the decision of the chairperson of NGT to rehear 18 cases, which were reserved for judgment, has raised concerns about both propriety as well as legality.

– The NGT, over the last two months, seems to have evolved four approaches to deal with litigations. First, dispose of existing cases. Second, form committees, comprising mostly people who were responsible for the problem, and outsource even adjudicatory functions. Third, refuse to entertain matters on the ground that the govt has approved the project or other hyper-technical grounds. And finally, rehear cases which were earlier reserved for judgment.

– One is not expecting the NGT to always give judgments in favour of those who approach it for protecting the environment. Rather, the cause for concern is the general reluctance of the tribunal to hear matters on merit, to consider the decision of the govt as virtually sacrosanct and submissions of project proponents as cast in stone. It must not be forgotten that the NGT is not a special tribunal, but a specialised tribunal set up to adjudicate on complex environmental issues through the use of both judicial and technical expertise.
