CONCLUSION Leakage occurs in different components of the distribution system; transmission pipes, distribution pipes, service connection pipes, joints, valves, and fire hydrants. Leaks waste both money and a precious natural resource, and they create a public health risk. The primary economic loss is the cost of raw water, its treatment, and its transportation. Leakage leads to additional economic loss in the form of damage to the pipe network itself. For examples , erosion of pipe bedding and pipe break, and to the foundation of roads and buildings. Risk to public health can be caused by contaminants entering the pipe through leak openings if water pressure in the distribution lost. There are three methods to trace the pipe’s leakage: 1.

CONCLUSION

Leakage occurs in different components of the distribution system;

transmission pipes, distribution pipes, service connection pipes, joints, valves, and

fire hydrants. Leaks waste both money and a precious natural resource, and they

create a public health risk. The primary economic loss is the cost of raw water, its

treatment, and its transportation. Leakage leads to additional economic loss in

the form of damage to the pipe network itself. For examples , erosion of pipe

bedding and pipe break, and to the foundation of roads and buildings. Risk to

public health can be caused by contaminants entering the pipe through leak

openings if water pressure in the distribution lost.

There are three methods to trace the pipe’s leakage:

1. Tracing pipe leakage with visual method.

2. The using of Leak Noise sounding Corelator.

3. Tracing pipe with the gas method.

OBJECTIVES

To study the method of detecting leakage in the water pipe.

Enable to identify the detector method function pipe leakage.

To determine this tool location used.

Enable to see with more detailed steps to use equipments.

Tracer Gas Technique

This method takes a lot of costs. It carried out in pipe condition that is no water in pipe flow. Therefore it needs time to evacuate the pipe. With this technique, a non-toxic, water-insoluble and lighter-than-air gas, such as helium or hydrogen, is injected into an isolated segment of a water pipe. The gas escapes at a leak opening and then, being lighter than air, permeates to the surface through the soil and pavement. The leak is located by scanning the ground surface directly above the pipe with a highly sensitive gas detector. The equipment will be analyzing leak distance which occurred from station point. usually it seldom been used because it should make sure all valve closed securely so that gas put inside pipe do not go out through it.
