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
