WATER:
Water Consumption
High
levels of water
use cause both
environmental
and economic
problems. On
the environmental
side, high consumption
places stress
on rivers, lakes
and groundwater
aquifers
and may require
dams and flooding
with serious
ecological impacts.
As well, the
discharge of
polluted water
once it has been
used damages
aquatic ecosystems.
On
the economic
side, high levels
of water use
require ever-increasing
and expensive
investments in
water system
infrastructure
needed to gather,
deliver and dispose
of water (dams,
reservoirs, water
treatment facilities,
distribution
networks and
sewage treatment).
Canadians
obtain the majority
of their water
from surface
sources such
as lakes, rivers
and reservoirs.
However pressure
on groundwater
(water drawn
from aquifers
by wells) is
increasing rapidly
in Canada.
Canadas
OECD Ranking
Canada ranks
a dismal 28th
among the 29
nations of the
OECD in terms
of per capita
water consumption.
Only Americans
use more water
than Canadians.
Canada
uses 1,600 cubic
metres of water
per person per
year. This is
more than twice
as much water
as the average
person from France,
three times as
much as the average
German, almost
four times as
much as the average
Swede and more
than eight times
as much as the
average Dane.
Canadas
per capita water
consumption is
65% above the
OECD average.
In
terms of total
water consumption,
Canada is 26th
out of 29 OECD
nations, with
the United States,
Japan and Mexico
using more water,
in total, than
Canada.
Canada
has been criticized
repeatedly by
the OECD for
our excessive
use of water.12
Trend
Since 1980, overall
water use in
Canada has increased
by 25.7%. This
is five times
higher than the
overall OECD
increase of 4.5%.
In contrast,
nine OECD nations
were able to
decrease their
overall water
use since 1980
(Sweden, the
Netherlands,
the United States,
the United Kingdom,
the Czech Republic,
Luxembourg, Poland,
Finland and Denmark).
