L’eau sale : un génocide silencieux | Noureddine Smali | TEDxUniversitéLyon3


[Applause]
hello you have
of water today I mean you
drank clean water
certainly it seems normal to you
commonplace
yet for many people
it’s a real feat
you have to walk several hours to
go up the river with a fort
height difference
then you have to go back up with cans
seals from 5 to 25 liters
it’s usually children and
women who are responsible for this chore
daily but this water is often
contaminated with feces
bacteria from parasites viruses
the UN estimates that 30% of the population
world sees dirty water with
consequences of the terrible consequences
it’s only two million people
will die every year because of
waterborne diseases
you understand it I’m going to talk to you
access to drinking water in the countries
from South
how is it going down there and this to
through my experience of these 25
last years or with my teams
we have installed more than 350 projects
to allow four million
people to have water let’s take a
city ​​like kikwit the equivalent of lyon
in democratic republic of the congo a
million inhabitants apart whose
facilities are obsolete
the water tank leaks the pumps do not
not working
the population has doubled in very few
time the authorities need
to quickly invest the needs are
huge but the state’s coffers are
empty
so we go authorities will do
appeal to the lenders the banks
of development
there are over a hundred of
world bank the african bank of
development the French arrangement of
development
their mission is to grant
credits at very low interest rates
low over a very long period
hong if the record held at an office
of studies will be selected he will do
the inventory of the existing
how many kilometers of driving he
must change is what we do a
new tank or do we
rehabilitate the existing and it will define
a second stage budget we will make a
before detailed project
this time with the list of
equipment and works to be completed at
from there we will select a
work company that will deliver and
install and start
equipment all this appears pretty
fluid but on the ground very quickly
will realize that between the vision of
the engineer who dreams of smart cities and
the expectations of call the madam
diallo
there is a whole world she wants the water
down the river be pumped filter
and disinfect store and distribute
quickly there this year the most
quickly possible for all
actors who realizes the project it’s a
permanent nerve crisis
the project is oversized there has been
several speakers nothing works
as expected and the consequences for the
mayor of kikwit
is that between the moment he expressed
his needs and when he goes there
finally have water at the tap there are eight
at fifteen years an eternity
the cost price of the cubic meter of water
is $ 8
here in lyon you pay three of their
five years tessa a includes tax
sanitation
we know that in Africa most of
people the vast majority can pay
maximum $ 1 per cubic meter
so is this a fatality
no, of course, is there any
solutions
Yes
the first is that budgets for
the world’s drinking water is increasing in
1848 there was a very beautiful sentence
on the posters of the Zero Revolution
has the right to the superfluous as long as everyone
does not have the necessary
we will have to put in place
taxes on the superfluous but a
other level what can we do
we are a group of men and
women in the field and for five years
we reflect on how to change
of software find new models
to go faster than it works
that it lasts in time and that it is
duplicable one of the ideas that I’m going
submit you is to put
together a design office
a works company a company
of exploitation or slabs
operating for together meet
design tenders and
integrated realization from the beginning
social engineering be listened to
users
the customer will have three requirements
very simple one that offers encrypted
that will be delivered to him does not exceed
the dollar floor price
secondly everything is done
quickly in a year and a half
maximum
thirdly that companies
undertake to guarantee the maintenance
for 5 10 and 15 years this will have some
beneficial consequences
companies will adapt to this price
floor there are technical solutions
the simplest is already to reduce the
per capita flow we learn in
engineering schools in strasbourg en
germany in spain it takes 150
liters of water per capita
we were very well
nobody can pay 150 liters of water
in Africa we are between 20 and 50 liters
will reduce the facilities
reduce investments
the very short time will force the
companies to buy local
no need to bring in containers
from germany of turkey
if there are factories in Congo, there are some
or in the subregion in abidjan at
ghana in kenya
because in three years when you
go break a pipe and it happens
if you do not have the same brand the
same diameter all stops I saw some
facilities for hundreds of euros a
contactor failed
we can also imagine pumping a water
raw in the river do a
coarse filtration and then they
treated at home with
small sand filter manufactured
locally tanks are found
everywhere and we integrate a membrane
ultrafiltration that will stop all
bacteria every virus every
parasites for slums
water shops are installed powered
either by the network or by truck water
will be treated filtered on-site sold
the container as is done often but
also we can feed in a radius of
1500 m the 500 families and they have the
ability to pay with their phone
mobile
it is done enormously they can
pay half a dollar a dollar a day
because we are facing an audience that does not
can not pay 30 or 40 dollars at the end
of the month then saw the stake we speak of 2
billion people who drink a
dirty water in cases where the price of
return we would not arrive at this price
can not imagine that a
government an institution a bank
University development compensates for this
price you will tell me no this morning
I took the tram
I paid a euro 80 the price of the ticket
only covers a quarter of
investment and fees
operation
the rest is the city of Lyon the
region the state agglo that subsidizes
because lyon without means of transport
in common
it would be hours of traffic jams
lost time of crisis pollution
of asthma of the dead for drinking water
it is the same, that is to say that
children you saw earlier at
instead of
spent four hours a day every
days to carry sauces they
could go to school
if he could if parents instead of
run to the clinic all three
four months to buy
antibiotics
everyone would be winner ladies
gentlemen you see the solutions
exist they must be put in place
quickly
it is urgent thank you
