Turn off the water tap when
you`re not using it ,
like when you are
brushing your teeth.
1
Make it a full load. Only run the
washing machine or dish-
washer when full. You can
save energy too by drying
the clothes on a clothes line.
2
Take a short shower instead of
a long bath can also help to save
energy. Get wet. Turn off the
water and lather up. Then
rinse off.
3
Install faucet
aerators, low-flow
shower heads and
toilets with smaller flush
Water plants in the evening .
Less water will evaporate
and more will reach your
plants.

Without it, there would be no
vegetation on land, no oxygen for
animals to breathe and the planet
would look entirely different than
it does today.
Water is necessary to keep
people's bodies and the
environment healthy and should
be valued and protected as a very
precious resource.
Water affects
all aspects of
life

Aqueduct is a 17th-
century aqueduct in
Malta, running through
Balzan, Birkirkara,
Fleur-de-Lys and Santa
Venera. This was built
by the Order of Saint John from 1610
to carry water from Dingli and Rabat
to Valletta. The Aqueduct was
inaugurated on 21 April 1615 and it
remained in use until the 20th century.
It is named after Alof de Wignacourt,
the Grandmaster who financed its
building.
What is the
Wignacourt
Aqueduct?
Malta is surrounded by seawater.
Rainfall is very limited. Malta’s
groundwater is pumped at a rate well
above the natural recharge rate.
The result is that the island’s
aquifers are slowly being invaded by
seawater, increasing the salinity of
the water available.
Malta depends on seawater
desalination (reverse osmosis), as a
source of water for the majority of
households. In 2010, 56% of Malta’s
potable water was produced by
desalination, utilizing 3.8% of
Malta’s electricity generated at a
cost.

It is common knowledge
that if the reverse osmosis
plants are put out of
service by a massive oil
spill or a similar disaster ,
the entire country has only
three days’ drinking water
supply.
Besides the quality of the
groundwater has degraded by
the increasing concentrations
of nitrates from the downward
movement of fertilizers and
animal waste into the aquifer.
