The importance of water in our lives

Town or community water supplies are sometimes drawn directly from nearby rivers or lakes.

Good Habits

Rivers and lakes can supply water. Springs These are found where underground water flows out of the ground naturally without the use of bores, wells or pumps.

Springs often occur towards the bottom of a hill or on sloping ground. Rock catchment areas and rockholes Sometimes large the importance of water in our lives outcrops contain low areas in which water is trapped. These low areas make good natural dams. Often a wall can be built to increase the amount of trapped water. Top of Page Excavated dams Excavated dams are made by scooping out soil to make a large shallow hole. These dams are sometimes placed at the bottom of a slope to aid water collection.

However, this can only be done in areas where the soil will not allow the water to drain away very easily through the ground. For example, in clay soils. Soils which do not allow water to drain away are called impervious. If a community wants a dam in an area where the soil is not impervious this can still be done by digging the hole and lining it with clay or an impervious liner, such as concrete or heavy plastic.

Excavated dams are often used by farmers to supply water to stock. There is often a layer of water lying beneath the ground surface, trapped by an impervious layer of rock which will not the importance of water in our lives it to drain away.

The water may be close to ground level or it may be deep in the ground. This layer of water is the importance of water in our lives the water table. When this water table is close to ground level the water may actually come to the surface and create a permanent wet area called a soak. This usually occurs in low lying areas or hollows.

Soaks are affected by changes in the depth of the water table. That is, if the water table drops then soaks may dry up.

Some causes of this can be drought or overuse of ground water by people.

Top of Page Rainwater tanks The the importance of water in our lives which falls on the roofs of houses is often collected using roof guttering leading through a pipe to a storage tank.

Environmental Health Practitioners are encouraged to use the guide when planning how to prevent these hazards from contaminating rainwater, straightforward monitoring and maintenance activities and, where necessary, corrective actions. The monograph can be found on the enHealth website or by using a search engine with the title of the monograph.

Bores and wells These are holes drilled into the ground deep enough to find a permanent long-lasting body of water.

Earth Would Look Like This:

A pipe runs down the the importance of water in our lives into the water and a pump is used to get the water up to ground level. The water is then pumped to the community. Artesian bores Sometimes when a bore is sunk into a low lying area the water gushes out of the hole under its own the importance of water in our lives. This water is under pressure because it is part of an underground body of water much of which is at a higher level than the bore opening. This kind of bore is called an artesian bore.

A water supply taken directly from a bore or well is often called groundwater. The water which comes from any of these sources may be salty, cloudy, smell unpleasant or have germs in it. Water of this kind would require special treatment to make it potable.
