Kalri — another Manchhar in the making
By Humair Ishtiaq

KARACHI: While the toxic waste being released into Manchhar and its subsequent outflow into Indus continue to make media headlines, the contamination of Kalri, which is one of the main sources of water supply to Karachi and Thatta, has so far escaped public attention. As things stand today, Kalri is just another Manchhar in the making.

As confirmed by a spokesman for the Karachi Water and Sewerage Board, 450MGD of Karachi’s total supply of 550MGD comes through Kalri, and that should be enough to make alarm bells ring, but that has not been the case so far.



The absolute calm prevailing in the Sindh irrigation department in this regard is apparently based on confusion among its various officials and wings. Secretary Ashfaq Memon, for instance, outrightly denies any problem with the post-Kotri outflow that takes the Kalri-Baghar Feeder Canal to reach Kalri. “There is no problem at all in the KB Feeder because there is no chemical industry in Kotri,” he told Dawn after repeated messages were left on his cellphone.

In contrast, Kotri Barrage Chief Engineer Manzoor Ahmad Shaikh was equally firm when he described the Kotri industrial area as “a huge problem that needs to be tackled quickly”. Apparently, he could afford to be frank on the issue because the task doesn’t fall under his purview.

Incidentally, the argument raised by the Irrigation Secretary — the absence of chemical units in Kotri — is exactly the same as the official stand of the Kotri Association of Trade and Industry (KATI). Senior Vice-President Tariq Baloch is a highly vocal defender of the cause of his fellow industrialists, and would hear nothing against the community. But Abdul Razzaq, the estate engineer appointed at Kotri by the Sindh Industrial and Trading Estate (SITE), condeded that “25 per cent pollution of the KB Feeder is because of the waste” being churned out by the industries.

According to independent researchers monitoring the water flow with a certain level of assistance from the Environment Protection Agency, post-Kotri water, for instance, carries an additional 15 to 20 units of magnesium and its concentration in Kalri is already beyond the accepted limits. Not much different is the case with other pollutants.

A fresh sample study conducted at the request of Dawn confirmed that the concentration right now is more than twice of what the WHO guidelines suggest. Manchhar, of course, has 10 times more pollution, but since those concerned are showing the same level of neglect and carelessness as was the case with Manchhar in its initial days, the fate of Kalri may not be much different.

Looking at the overall water contamination scenario in Sindh, it represents a bleak picture; bleak enough to disappoint even the most diehard of optimists. Effluents from Punjab flow into Sindh through Ghotiki, while the waste coming from Balochistan in the shape of Hairdin flows into Hamal in Larkana. The waste produced by the entire Upper Sindh joins the flow and, in turn, Hamal falls into the controversial Main Nara Valley (MNV) Drain at Faridabad. This load of poison, which includes everything and anything that one can possibly think of — magnesium, mercury, phosphates, nitrates, arsenic, chromium, cadmium, fertilizers, pesticides, human waste, you name it — then enters Manchhar at Zero Point on Manchhar Bund.

While the considerable population of fishermen in the area suffers from this contamination, it is itself a source of pollution in the lake, which is an unfortunate depository of the entire human and animal waste of the area. Not just that, the chemicals being used by the fishermen to kill deep-water fish so that they come up dead on the surface is another potent source of contamination.

It is no wonder that the local WHO representative, Dr Khadim Lakhiar, finds the water and the fish in Manchhar “absolutely unfit” for human consumption. The irony is that this fish-catch is dried and packed at Manchhar for onward movement to Hyderabad and Karachi where it is used as part of poultry feed, taking the poisonous cycle from water and fish to chicken and eggs.

The only source of fresh water supply to Manchhar in the wake of the extended dry cycle that hit the Indus in recent years, resulting in the closure of the Danistar inlet, is the water stream flowing down from Nai Gaaj, which is an enormous rocky desert that separates the Kachho area ahead of Juhi town in Dadu district from the reaches of the Gorakh hill station. The government’s plan to build a dam on the Nai Gaaj site has led to serious reservations among the Manchhar population. These reservations, amazingly, are as intense and along the same lines as are Sindh’s doubts about the Kalabagh Dam.

Ghulam Mustafa Mirani, vice-president of the Pakistan Fishermen Forum, echoed the feelings of many when he said that the Nai Gaaj Dam may well leave Manchhar a thing of the past. Maula Bux Mallah, a local fisherman, nodded vigorously, insisting that a poisonous Manchhar was “still better than a dead Manchhar”.

The plaque at the dam site describes the activity as the “inauguration of the feasibility report”, which appears to be a comfortable way out for the authorities to calm down the locals. Rafiq Jamali, the MNA from the Dadu-Juhi constituency, used the ploy when Dawn contacted him over the phone in Islamabad. “It is just a feasibility report. I don’t know why people should feel so strongly about it,” he said. It may be beyond him, but with two feasibility reports already in hand and a third one under process, the mood of the authorities is not beyond the locals, and they are concerned; very concerned.

Getting back to the water flow, though, the story doesn’t end at Manchhar. Through the Aral Wah, the liquefied poison flows into the Indus where it is joined by the chemical waste thrown out by the Lakhra and Jamshoro power stations and a multinational firm in the vicinity. While there is intense effort on the part of all government functionaries to absolve the two power stations of any wrongdoing, no one is able to explain why there was such a huge difference last year between the havoc that gripped the Hyderabad, Latifabad and Kotri areas, and the relative calm elsewhere along the Manchhar route till it reached Jamshoro.

After all, it was the same Manchhar water flowing all the way through, but the number of casualties post-Jamshoro were dramatically different. Apparently, there has to be something seriously wrong with the Jamshoro effluent, but instead of trying to locate the problem, the authorities — of all shades and hues — are trying to cover up. DCO Jamshoro Qabool Shaikh blurted out the obvious dilemma of the authorities. “If we close the two power plants, you people will start shouting about power failures. We don’t have a choice, you see.”

Faced with a Hobson’s choice, the DCO has allowed the power stations to continue adding their waste to the Indus. This he has done on the basis of a certificate issued by Abu Adil, the chief engineer of the plants concerned. That the DCO found no reason to have an independent opinion tells its own tale, especially when the chief engineer concerned was one of the officials charge-sheeted last year after the Hyderabad tragedy, and had to secure protective bail from the Sindh High Court.

Sources in the EPA, Hyderabad, say the agency had serious concerns about the chemical condensers and coolants being used by the Lakhra and Jamshoro plants, but it had its hands tied due to the absence of proper standards available in the country. Also, the plant managements “do not share complete data” with the EPA.

When contacted, Mr Adil waved a bunch of papers as a proof that the plants were not guilty, but refused to share that ‘proof’ with Dawn. “I can’t do that, of course,” he said with an evasive smile, asking his subordinates why tea had still not been served.


Back to the water flow, it reaches Hyderabad through Jamshoro where it meets the fresh input from downstream Sukkur. Almost the entire sewage of Hyderabad and Latifabad falls in the Phulleli\Pinyari canal that carries it along with the drinking water to Badin, while the KB Feeder is joined by the Kotri effluent and runs down to Kalri from where it supplies water through Dhabeji and Gharo to Karachi and Thatta.

The most disturbing thing is that the whole route is official, and every single drop of poisonous waste that mixes with drinking water along the route is officially supposed to fall right there. Nobody is flouting any rules. This is what the government plan has been, and continues to be.

The tragedy last year has meant media focus on the release of water from Manchhar, and everyone in the irrigation department wastes little time in taking pride in the fact that nothing of the sort has happened this year. The fact of the matter is that what is happening this year is no different from what took place the last year. The MNV brought the same toxic waste, water from Manchhar had to be released beyond a certain level, and nothing changed at Jamshoro either. The only difference is that there is enough water in the Indus flowing downstream to dilute the toxins. This is what has saved the skin of all concerned. But it is simply a matter of converting poison into slow-poison. It will kill, but it will kill slowly. This is the net worth of the irrigation department’s pride.

The authorities are hoping for much improved water supply this year in the wake of heavy snowfall in the north and the expected more-than-modest monsoons in the months ahead. In fact, they are preparing for a low-to-medium-level flood. All this means there may be no water deaths this year. What may happen in subsequent years when the dry cycle will inevitably return is anybody’s guess.

The authorities appear to have no plans to handle that situation, as was duly confirmed by Manzoor Shaikh, the Kotri Barrage chief engineer. The water can’t be allowed to rise at Manchhar beyond a certain level and toxic water has to be released into the Indus, and if there is not enough fresh water in the river, as happened last year, what would the government do, he was asked. “We will look up to God,” he said.

A few more minutes into the discussion, he stressed that there was “nothing to worry about” because of the wet cycle that is expected this year and may last for a while. In practical terms, he is expecting the wet cycle to last till at least five years when the Right Bank Outfall Drain (RBOD) is expected to get functional. Wasn’t this his hope? “You can say that,” he said, with a laugh that exposed a helpless official of a clueless government department.

A possible solution?

KARACHI: There are serious reservations about its future because of the bad experience with the Left Bank Outfall Drain (LBOD), but the Right Bank Outfall Drain, or the RBOD, represents the biggest hope on the part of the government in terms of finally being able to take effluents directly to the sea. Work on the project is continuing, but the RBOD will not be functional for at least the next four to five years. This calls for some arrangement to manage the toxic waste in the interim period, and the only technically plausible way is to treat the effluents before releasing them into the water stream. While government officials tend to reject the notion straightaway, citing the “huge cost” supposedly involved in putting up such an arrangement, they are surprisingly unaware of an alternative low-cost process suggested in the wake of the Hyderabad tragedy last year.

Describing the plan, Dr Ahsan Siddiqui, a trained chemical analyst, told Dawn that it was possible to treat 90 per cent of the effluents in the MNV Drain through the electro-static process, which involves putting up electrodes every eight kilometres along the MNV route. With each electrode costing around Rs3.5 million, the whole scheme involves nothing more than Rs30-35 million.

While the Environment Protection Agency had initially shown much interest after finding the proposal technically and financially feasible, a change in the EPA hierarchy resulted in loss of interest on the part of the agency, says Dr Siddiqui.

Another mechanism, developed by Professor Ashfaq Pirzada, a post-graduate chemical engineer by training, and part of the faculty at the Mehran University, Jamshoro, seems to be a practical solution to the problem posed by the Kotri industrial waste. Prof Pirzada has devised an extremely low-cost mechanism to not just treat effluents, but also to get byproducts out of them.

Electrodes along the MNV Drain and low-cost treatment plants at Jamshoro and Kotri may go a long way towards ensuring the supply of potable water to the majority of the population in Sindh, but apparently there is little hope in this regard because Irrigation Secretary Ashfaq Memon, when contacted, said he had no idea what it was all about. — HI
