Kalri —
another Manchhar in the making

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 |
