Ramji Tripathi took bottles filled with Ganga water to the offices of the Kanpur Jal Nigam and the Ganga Pollution Control Unit to confirm his strong hunch. Tripathi is a seer and the national coordinator of Kanpur-based Ma Ganga Pradushan Mukti Abhiyan Samiti, an outfit led by Swami Harchetan. When he started sprinkling the “holy water ” on the officials, the police was called and he was forced to leave the premises. Tripathi says he did this only to debunk the claims of officials that river-cleaning operations were yielding results. “Why did they stop me from sprinkling holy water,” he asks. His organisation is now going to launch a movement to boycott bathing in the Ganga in the next Kumbh Mela, which begins on January 15, 2019. After three decades of efforts to clean the national river, it is a sad state of affairs that the river is not even fit for bathing. According to a map of Ganga river water quality presented by the Central Pollution Control Board (CPCB) to National Green Tribunal (NGT) in August 2018, only five out of 70-odd monitoring stations had water that was fit for drinking and seven for bathing (see ‘The filthy stem’,).
Initiatives to clean the Ganga began with the Ganga Action Plan I in 1986. Till 2014, over Rs 4,000 crore had been spent. But the river has remained dirty. So when the National Democratic Alliance government launched the Namami Gange in mid-May 2015, there was a new hope. It was the biggest-ever initiative—over Rs 20,000 crore was allotted. Prime Minister Narendra Modi made it his personal agenda and set a deadline: “Ganga will be clean by 2019”, it has now been extended to 2020.
Namami Gange is being implemented by the National Mission for Clean Ganga (NMCG), and its state counterparts—State Programme Management Groups. NMCG would establish field offices wherever necessary. The National Ganga Council (NGC) was created.
And to give it utmost importance the Prime Minister was made the head of it. This council replaced the National Ganga River Basin Authority (NGRBA). NGC would have on board the chief ministers of five Ganga basin states—Uttarakhand, Uttar Pradesh (UP), Bihar, Jharkhand and West Bengal—besides several Union ministers and it was supposed to meet once every year.
The Water Resources, River Development and Ganga Rejuvenation Ministry signed Memoranda of Understanding (MOUS) with 10 other ministries to synergise the activities under the Namami Gange. The government said it would involve grassroots level institutions such as urban local bodies and panchayati raj institutions to implement the programme.
An Empowered Task Force, headed by Union Water Resources Minister, was created and it has on board the chief secretaries of the five Ganga Basin states. It was supposed to meet once in every three months. State Ganga Committees have been formed, which would be the nodal agency to implement the programmes in a state. Besides, these committees would conduct safety audits of the river and take remedial measures.
The government has said that the new projects are delayed because land acquisition and other related activities were taking a lot of time. However, poor performance in rehabilitating old STPs does not stand the test of time scarcity.
The issue is just not with the construction or rehabilitation of STPs but also their performance. Every STP installed has design parameters for Biological Oxygen Demand (BOD) and Total Suspended Solids (TSS). Consider the STP at Kanpur, which holds the dubious distinction of being home to the “most polluted stretch” of the Ganga. The 5 MLD domestic waste water treatment plant at Jajmau in Kanpur had BOD and TSS level in effluents as 65 mg/litre (against design parameter of 30) and 92 mg/litre (against design parameter of 50), according to the April-May 2018 report of Kanpur Jal Nigam. The report says that BOD and TSS levels of the effluent is higher than the norms because industrial waste and chemicals are illegally mixed with the influents in a plant not meant to treat industrial pollutants.
Another problem with STPs is that they are not able to get the total amount of influents, primarily due to lack of sewerage network in the city. A total network of 2,071 km of new sewer line projects was sanctioned after Namami Gange came into being but only 66.85 km has been laid. The STP that treats domestic waste water in Kanpur’s Jajmau has a capacity of 130 MLD but its April-March average was only 60.5 MLD. According to NMCG, all the existing plants in Kanpur have a capacity of 414 MLD but are getting only 230 MLD as influents.
For any city, STPs are being designed according to their sewage generation. The problem lies in the way sewage generation is estimated. “The estimation of sewage generation is based on the assumption that 80 per cent of the water supplied is returned as waste water. Some recent data compiled by Central Pollution Control Board (CPCB) shows that actual measured discharge of waste water into Ganga is 6,087 MLD, 123 per cent higher than the estimated discharge of waste water,” says a paper authored by Raghu Dayal in the Economic and Political Weekly in 2016. V K Mishra, president of Varanasi’s Sankat Mochan Foundation (SMF), reiterates that the very methodology of calculating sewage generation is faulty. SMF was given the task of constructing an STP of 35 MLD near Assi Ghat at Varanasi in 2010. Mishra, who is also a professor in IIT-BHU, says, “We carried out a three-day schedule for the Assi drain and to our utter surprise we found that the discharge was 63.5 MLD. That was way back in 2010.” Mishra says that when the entire city is not having piped water supply, how can this become the criteria for calculating sewerage generation? Mishra’s argument also finds support in UP State Annual Action Plan (SAAP) 2017-2020, which says the coverage of piped water supply in Varanasi is less than 60 per cent. In Kanpur and Allahabad it is less than 60 and 40 per cent respectively. Kanpur, Allahabad and Varanasi are considered hot spots of Ganga pollution in the entire stem.
But domestic sewerage is not the only cause of concern. The industry, especially the tanneries in Kanpur’s Jajmau area have several times attracted the wrath of both the Supreme Court and NGT. The government of UP said to NGT on March 30, 2017 that it has, in principle, taken a decision to shift the tanneries from Jajmau to some other place that is under consideration. However, the government was also open to the idea of installing appropriate anti-pollution devices, including a chromium recovery plant. It is mandatory that tanneries treat chromium either through their own small plant or a made in cluster and then transfer the waste to a Common Effluent Treatment Plant (CETP) run by the government. According to submissions made by the UP government in NGT there are three clusters housing tannery industries—Jajmau, Unnao and Banther. Jajmau has the maximum concentration of 400 tannery industries and NGT wrote in its order, “The industries at Jajmau are discharging much more than 9 MLD industrial effluents, mainly containing chromium. There is no enforcement of consent conditions by Uttar Pradesh Pollution Control Board which requires all industries to send their chrome liquor to the Chrome Recovery Plant and pay for the treatment. Industries are finding it easy to dispose their entire waste, including the chrome liquor, in the common drain which carries both domestic as well as industrial waste.” NGT’s observations find eerie resonance in the April-May 2018 report of Kanpur Jal Nigam. It says that chromium concentration in tannery effluent is 110.2 mg per litre.
When Down To Earth (DTE) visited the CETP, chromium had formed a separate layer over the waste water and was visible with naked eyes. Against the design parameter of 175 BOD per 100 ml and TSS 200 mg/litre the effluent had the former at 203 mg/litre and the latter at 253 mg/litre. A visit to Jajmau and nearby villages unveils the reality on the ground. There is no board outside any of the four tanneries right on the bank of Ganga in Wajidpur village and they seem to be running almost anonymously. One can see that they are discharging waste into the Ganga. “Outlet pipes throw dust which we inhale every day,” says Chhotu Nishad, a resident, showing his pierced skin. Hair fall, skin infections, heart and lung problems are common in every family DTE spoke to.
Sheikhpur village is located just a few kilometres away from the Jajmau tanneries. Lakshmi Shankar Nishad, a 50-year-old resident, shows his left foot on which skin has almost peeled off. “We are suffering from many more skin infections. This is because tanneries are discharging their waste water directly into drains and the water of drains has mixed with groundwater which has become infected.” Another resident, Sri Krishna says people are becoming impotent in the village and doctors tell them to leave the area. “How can we? Our homes and farms are here,” he says.
Not sensing any progress in controlling pollution, NGT in July last year gave more than 100 specific directions related to 86 drains going into the Ganga, Ramganga, Kali and the Pandu rivers. “The government agencies have submitted compliance report regarding most of the directions. But what I gather from the field is that most of the submissions are coloured,” says M C Mehta, who has been fighting cases on the Ganga in the Supreme Court and NGT.
Besides cleaning the Ganga, the Namami Gange also talks about afforestation as an important activity as it helps groundwater recharge. According to NMCG, it has already spent Rs 114 crore on afforestation but to no avail. Showing the plants being planted, assistant professor in Allahabad University Pramod Sharma says, “They have planted kachnaar and gulmohar plants. They can only be used for decorative purposes. What is required for the Ganga is bargad, peepal, gular and neem as they help in better conservation of water.”
Challenge II: Restoring the flow
There is another fundamental problem that will ensure the holy river remains dirty. A river is a self-purifying system only when water flows through it. The Ganga fails this basic test except during monsoons. So it’s not just about unclean Ganga. It is about the existence of Ganga, experts say. Vijay Dwivedi, an Allahabad-based activist, who has formed a Ganga Sena which takes up cleaning of the river regularly says that in monsoons the water level in Ganga is good enough. “But you should have come in April or May. There is not even knee deep water. People graze cows, learn driving and play cricket on the surface of Ganga.” Gopal Nishad, a boatman at Sangam says, “Even the fish die in summer due to lack of water. People coming to ghats usually don’t go for boat rides in summer and it hits us badly.”
B D Tripathi, in-charge of Banaras Hindu University’s Ganga Research Centre, says, “The water level in the river is going down at an unprecedented rate. Also if the flow in the river is maintained it can solve the problem of 60-80 per cent of organic pollutants and we may not require such an elaborate programme.” He also says that unlike other rivers, the Ganga has three special properties because of the path it treads naturally. “The Ganga has medicinal properties that can treat skin infections. These properties come due to medicinal plants on the path of Ganga. Also the Ganga is very rich in minerals and has bacteriophages which kill the bacteria. If you chain the Ganga with barrages and canal diversions and therefore alter its natural path, it will lose these properties.” He says due to restrictions and decrease in flow, the velocity of water decreases and siltation increases and therefore minerals of the water settle down at the riverbed.
All these surmises get credence in the paper published by IIT-Kharagpur’s Abhijit Mukherjee and others in August 2018 which says that according to their estimates the baseflow amount of the river has decreased by 56 per cent in 2016 as compared to the 1970s. The decrease in flow has led to an increase in groundwater extraction for various uses.
According to a report published by Wildlife Institute of India in May 2018, 16 existing, 14 ongoing and 14 proposed hydroelectric projects on the Bhagirathi and Alaknanda river basins have turned the upper stretch of the Ganga “ecological deserts”. To deal with these projects, A K Gosain, professor at IIT-Delhi and a member of the panel that has drafted the Ganga protection law, says, “The designs of hydroelectric projects can be tweaked in such a manner that they consume less water. It may raise the cost of the projects but should be done for long-term preservation of the Ganga. It is now for the government to decide whether it comes out with such a mandatory policy or not.”
Challenge III: Sludge control
The river has another persitent problem that is going to be more pronounced. “I have a toilet in my home but the two pits under are overflowing with waste. How do I use it?” says Rashid Ali of Chhapri village in Allahabad district. He and his family is back to defecating in the open near the Ganga. Other villagers also narrate similar issues and say the construction of toilets has compounded their problems because the overflowing toilets have also made their homes dirty. The damning indictment is supported by many people living in cities along the banks of the Ganga.
A staggering 99.93 per cent villages lying on the banks of Ganga, also known as Ganga Grams, have been declared open defecation free (ODF) by the government under the Swachh Bharat Mission (SBM). As per SBM data, more than 2.7 million toilets have been constructed in over 4,000 villages till September 17, 2018. Not surprisingly, CAG in its December 2017 report casts aspersions on the claim. The report said the state government was to verify the ODF status through its own teams or through a third party but 1,144 villages of UP and Bihar didn’t get it done. The whole objective of making villages lying in the Ganga basin to be ODF was to reduce the faecal coliform levels in the Ganga. Against the standard of 2,500 per 100 ml, the faecal coliform ranged from 2,500 to 2,40,000 per 100 ml in the Ganga basin cities in May 2018, as per data provided by pollution control boards of five states along the Ganga basin.
A back-of-the envelope calculation by the Centre for Science and Environment (CSE), a Delhi-based non-profit, showed that about 180 MLD sludge would be generated in five Ganga basin states when they become ODF (see ‘Sludge crisis’,). And if proper faecal sludge management is not in place, it would invariably pollute the Ganga. What should cause further concern is that faecal sludge is a bigger pollutant than sewerage. While the BOD of sewage is 150-300 mg/l, that of faecal sludge would be 15,000-30,000 mg/l.
