WATER SUPPLY



154



English for Civil and Industrial Construction Engineering



Water supply diagram of a town

A water supply for a town usually includes a storage reservoir at the source

of the supply, a pipeline from storage reservoir to the distribution reservoir near

the town, and finally distribution pipes buried in the streets, taking the water to

the houses, shops, factories, and offices. The main equipment is thus the two

reservoirs and the pipeline between them. The function of the storage reservoir

is to keep enough water over one or several years to provide for all high

demands in dry periods, and the distribution reservoir has the same function for

the day or the week. The storage reservoir by its existence allows the supply

sources to be smaller and less expensive, and the distribution reservoir similarly

allows the pipeline and pumps to be smaller and cheaper than they would be if it

did not exist.



154



English for Civil and Industrial Construction Engineering



The storage reservoir

In the United States, some of whose cities have the largest water use in the

world per person, the average use per person varies from 200 to 5000 liters per

day, averaging some 500 liters/day/person. However, it must not be assumed that

colder countries will eventually reach the same level of use, because much of the

highest US demand comes from the water spent in summer on air conditioning

equipment and the watering of garden.



154

Water supply diagram of a house

Water engineers must therefore study the water use per person in their own

country and choose a figure based on the most advanced community there. The

chosen consumption per head must be multiplied by the estimated population at

the date for which the supply is being planned, some thirty years ahead or more.

The supply and the storage equipment must be designed to be large enough for

this period since neither of them is so easily extended as the distribution system.

This can be extended as the need arises and as the houses are built.

Once the volume of the required yearly supply has been calculated and

agreed with all concerned, including the fire department, it is so important to

make sure that it really is permanently obtainable from the catchment area

proposed. The catchment area is the area which drains towards the supply, and

the yearly amount of water drawn off to the storage reservoir cannot be more

than the rainfall on the catchment area and should usually be very much smaller.

154



English for Civil and Industrial Construction Engineering



Water cycle

A water supply may be obtained from surface water (rain) or from

underground water or both. Both are refilled by the rainfall, the surface water by

the run off, and the springs or wells by the water which enters the ground, the

infiltration water. These two quantities, plus the evaporation water and the water

used by the trees and plants, make up the total rainfall. Even if the community

water supply includes all the springs as well as all the surface water in the area,

it still does not obtain all the rainfall because of evaporation and the needs of

plant life.
