Introduction
This work will help you how to save and protect water and its importance.
How can we save water in order to have a better and cleaner world.
Definition of water
The word water comes from the latin aqua, it’s an odourless, insipid and
discoloured substance, formed by two hydrogen atoms and one oxygen atom.
Curiosities
Water is the component that appears in greater abundance in
the earth's surface, it covers 71% of the planet.
It is vital for all known forms of life.
Water on earth moves continually through the water cycle of
evaporation and transpiration, condensation, precipitation and
runoff, usually reaching the sea.
Curiosities
2/3 of our planet’s surface is covered with
water but only 0.6% is drinking water.
The remaining 97% of the planet’s water is
seawater, 2% is in glaciers and icebergs.
Water in natureIt can be presented in three possible states:
Solid:
Snow, Ice and Hail
Gas:
As water vapour, it is invisible and it can be found in the atmosphere.
Liquid:
Oceans, rivers and seas.
Rain, clouds and groundwater.
Water consumption in Portugal
• Water consumption in Portugal is estimated at approximately 7 500 000 000
m3/year in Agricultural, Industrial and Urban sector.
Waste of water by the three sectors
• Not all water demand by sector is actually used, there is a significant part
associated with inefficiency and loss of use on water that is actually
captured.
Effective Use of Water
It is a limited resource.
Corresponds to an economic interest at national level
Corresponds to an economic interest at companies level
Corresponds to an economic interest of the managing entities of water
Corresponds to an economic interest to the citizens
It is an important issue in terms of national and Community legislation
It is a strategic need
Easy ways to Save Water at Home
Turn off the water while soaping
hands and brushing teeth.
Take shorter showers, 5
minutes or less.
Install new toilets that use less than 1.5 lt of
water per flush
Wash the car with buckets of water and not with the hose
Use the water of washing the
vegetables for watering plants
Use the washing machine only with a full load
Curiosity:
Of all the water that is consumed at home, more than 75% is used in
the bathroom.
A discharge of flushing in a western country uses the same volume of
water that an inhabitant of a developing country consumes, on
average, in an entire day for their hygiene, for drinking, cleaning and
cooking.
Ways of saving water in Industry
Use automatic
water stop- cocks.
Put 1.5l bottle full of
sand inside of the
toilet cistern
If you notice a hose
and faucet to pour
water, close the tap
