WHAT IS WATER?

Water is a clear, colourless liquid which we drink from time to time. It has no smell when pure and clean.

USE OF WATER
1. Water is used for washing our clothes, our body and our dirty utensils.
2. It is used for cooking our food.
3. Water is needed by the body just as we need other foods such as meat, yams and milk. The water is used during the break down (digestion) of other food materials. The digested food is moved round the body in the water of the blood.
4. In big towns, water is used to carry away dirty things such as household refuse and faeces.

SOURCES OF WATER

Those of us from big towns often believe that the water we drink comes from pipes and taps. This is not correct. The pipes only bring us water from the source. The main sources of water are:
1. RAIN: rain brings water from the clouds and sky.

In the rainy season, rain water can be very clean. However, in the dry season it is always dirty because of dusts and other impurities in the air.
when rain falls, much of the water sinks into the soil till it reaches an impervious layer where it cannot pass through. It then travels along on this layer till it burst out, usually, at the side of hills and flows away. This type of water is called spring water.

  1. SPRINGS: It is usually very clean since the soil usually filters and removes the dust and germs of the rain water.

  1. STREAMS AND RIVERS: spring water runs into streams. Many of this streams flow into one another to form big rivers. Some stream water can be clean, but those that run through many villages are not. This is because the villagers empty their refuse in them.

Water from rivers are usually not clean. Rivers carry a lot of refuse and mud.
4. WELL: most of us have not seen wells because we live where there is water from taps or springs. Some of us, on the other hand, obtain water from wells. Wells are deep holes dug into the soil to obtain water which sank into the soil when the rain fell. Some wells may be deep while some may be shallow. Water from deep wells can be clean and good, but that from shallow wells are not.

CARE OF WATER SOURCES

SPRINGS: springs can be prevented from being polluted if fences are erected around them. Some government builds cement walls around them to prevent animals and men going near them.
WELLS: wells should be dug far away from latrines. They should be protected with cement walls. The opening should always have a lid which can be locked up when it is not in use. This will prevent children

throwing in dirt. It will also prevent some accidents.

HOW TO MAKE DIRTY WATER FIT FOR DRINKING

Small quantities of water used in the house for cooking and drinking can be purified in two ways.
1. BY FILTRATION: by using a clean cloth tied to the mouth of a pot, the dirty water is filtered. Porcelain filter are used by many people to filter their drinking water this removes floating particles and bacteria present in water.

  1. BOILING: if impure water is boiled for about 20 minutes the bacteria in the water will be killed. Boiling water should also be filtered.
    Large quantities of water for villages and towns are purified by adding a little quantity of chlorine to a large quantity of water. The chlorine kills bacteria and germs present in the water. Other substances used to purify water are potassium permanganate and chloride of lime.
