In a
country where there is a wide gulf between the rich and the middle
class, living in highbrow areas like Lekki, Ikoyi and Victoria Island in
Lagos is a sign of better life.
The belief of many residents of the Lagos
mainland is that those in these parts of the city are living large.
This is more reinforced by the fact that the crème de la crème of the
country have their homes in these places.
If one is to suddenly relocate from the
mainland to either Ikoyi or Lekki, the belief is that providence has
suddenly smiled on such individual.

But living in these areas has its downside as Saturday PUNCH has learnt.
A new finding has revealed that residents
who use water from boreholes constructed within their compounds in
these areas might unknowingly be drinking or using water contaminated
with their own human wastes.
Saturday PUNCH was on a finding
mission on the impact of human waste disposal in the Lagos Lagoon when
the fact came to light that the construction of septic tanks in these
highbrow parts of Lagos was not a good idea.
The Coordinator of the Lagos State Wastewater Office, Mr. Lekan Shodeinde, told Saturday PUNCH
that the water table in these areas was too shallow, which is why the
construction of both septic and borehole in the same compound is a
dangerous affair.
Shodeinde said, “A lot of houses in areas like Ikoyi, Victoria Island and Lekki are polluting the water table.
“Those areas are not supposed to put in
place septic tanks. In some of these areas, before you dig five feet,
you have reached the water table. Now, imagine going to such places to
put in place septic tanks which are constructed in such a way that the
waste seeps into the ground.
“They are simply soiling the water table.
These areas are supposed to have a centralised wastewater treatment
where the effluent emanating from households passes for treatment.”
This is the practice in many developed
countries where centralised sewers are put in place to cater for the
management of human wastes generated from each home.
According to Steven Burian, Stephan Nix
and Robert Pitt in their study on Urban Wastewater Management in the US,
the centralised system of management of wastewater has been in
existence in the country since the middle of the 19th Century.
Saturday PUNCH spoke with a
bricklayer, who explained that a standard septic tank could be as deep
as 10 feet. Considering the fact that the water table in these coastal
areas is comparatively shallow, it is possible that contamination occurs
to groundwater sources in some of the places.
Experts say there may be considerable
hazard for those who use water sourced from boreholes directly in these
areas, or those who do not have water treatment facilities or filters in
their homes.
Prof. Ebenezer Meshida of the Geoscience
Department of the University of Lagos, who also teaches at the Civil
Engineering Department of the Afe Babalola University, Ado Ekiti, Ekiti
State, said the type of water one can get in most parts of Lekki, Ikoyi,
Ajah and Victoria Island, is highly contaminated.
He said, “The water in the region is not
expected to be used as drinking water. That type of water can be used to
clean your car or flush the toilets. Any water you get around five
metres depth is highly dangerous.
“The type of water that is fit for
consumption in that area should be obtained from boreholes that are very
deep, deeper than third water level. Those who are experienced in
drilling boreholes understand that at the third water level, you get
fresh water. Sometimes you get to 200 metres or 300 metres before you
can get drinkable water but some will say it is too expensive.
“Those who build houses in that zone of
Lagos must be people with millions of naira in their pockets because it
is not a zone that is good for extracting drinkable water.
“What is usually obtained there is salty
or polluted water. Most of the diseases people fall prey to in Lagos are
from polluted water consumption.”
But what can be done by those who already have shallow boreholes in these areas?
Prof. Meshida said boiling of the water is an age-old system that still works fine.
He said, “Boiling is the first stage of
treatment. You can then filter after that. In those days, we made use of
filters that used candles. If you boil water from whatever source it
comes from and you filter it with a cloth and put it in the candle
filters, you can be sure you are safe.
“I will suggest that anybody who wants to
drink water sourced from shallow boreholes in such areas should go to
environmental chemists. They are in university chemistry departments.
They will help to analyse the water. They will be able to identify the
chemical composition and determine the best way to treat the water.”
A borehole contractor, Mr. Elijah Idowu, who runs Noble Fourstar Hydro Resources, explained to Saturday PUNCH the process it takes to reach a depth where drinkable water can be extracted in the Ikoyi-Victoria Island-Lekki zone.
He said, “Digging borehole is never a
child’s play in that zone because you will be talking of about 500 or
700 metres before one can reach a drinkable water depth.
“If an average depth borehole is about
N500,000 in another place, you will be looking at about N7m to dig a
borehole in a place like Lekki or Ajah.
“What we do usually is that we screen and
case the contaminated water part of the hole so that this does not
affect the fresh water we reach at the deeper part. Even with that, it
is still advisable if the residents install facilities which they can
use to filter the water before consumption.”
The Lagos Water Corporation has always
discouraged the sinking of boreholes in the Lagos metropolis but in a
city where a large percentage of the residents do not have easy access
to pipe borne water, this may be a futile plea.
The Lagos State Governor, Babatunde
Fashola, has also expressed concern over the proliferation of boreholes
in the state, saying they constituted long term environmental problem.
In a publication by PUNCH in
February 2012, the governor said the residents of the state were better
off with more water works than more boreholes in their different houses.
He urged the residents to make use of
domestic connections to their homes wherever there is a waterworks,
saying government would continue to build waterworks to bring water
close to various homes in the state.
When Saturday PUNCH spoke with
some residents of these upscale areas, it turned out that the situation
was more pathetic than most people would imagine.
Those who spoke with Saturday PUNCH at
Victoria Island, explained that the water they get from their boreholes
is so bad that it is sometimes totally unusable without being treated.
At Idejo Street, Victoria Island, a house
guard, Henry Okoro, went inside his compound and brought out a bowl of
water. It looked like one in which brown clay had been dissolved.
“This is the kind of water you get from the borehole here,” he said.
He said a tanker supplies the house with water from another part of Lagos every week.
“Some of these tankers collect N10,000 per supply, some N8,000,” Okoro said.
At Osapa London area of Jakande, Lekki, a
resident, Oyebola Ogunsanya, said even though she did not know that
septic tanks pollute the water table, she and other residents were not
bothered because the water in their borehole is not usable.
She said, “The water in the borehole is
like the colour of salt and it is very salty. Even after treatment, it
is still not usable. We pay tankers to fill our overhead tanks.
“Apart from the N7,000 I pay to fill the
tank which I share with another neighbour in my boys’ quarters, I spend
as much as N5,000 weekly on bottled and sachet water. The water from our
borehole is just unusable.
“Where I was living before, the water was
brownish in colour. You dare not even think about using it to wash, not
to think of drinking. What we do is that we treat the water so that it
could at least be used to wash clothes and toilets.
“We have a water treatment plant in the
house. After treating the water, we wait for about three hours. Then it
turns whitish. Only then can we use it to bathe or wash toilets. Even at
that, one still has to pour disinfectants in it.
“My sister in Lekki Phase I lives in a six-bedroom duplex and they have to get two tankers of water every week.”
But Mrs. Stella Billy-Ashogbon, who lives
in Ajah said the water in that side of the coast is cleaner than the
one obtained around VI.
She said, “Most people who live here are
those who would not spare cost in anything they do in their houses. Most
people know that the deeper you go, the cleaner the water becomes.
People who live here hire professionals to dig boreholes in such a way
that they would not worry about contamination.
“Most of those who dig shallow wells or
boreholes don’t use them for domestic purposes. They use it for
construction or to wet flower. To get a sustained supply, you will have
to go very deep.
“Those who build septic tanks around here
take it far away from boreholes and they can afford to make their
boreholes very deep, no matter the cost.
“All my friends living between Victoria
Island and Chevron area of Lekki have a similar problem though. No
matter how deep their boreholes are, the water they get from there is
always brown. They buy water all the time. Sometimes they even buy water
to wash clothes.
“Saying this place is supposed to have a
centralized sewage system instead of individual septic tanks is just
being idealistic. We like to be idealistic in the country instead of
addressing our own peculiarity.”
