The problem of leaking water supply pipes may seem like a minor issue, but it has far-reaching implications. The following is a list of ten hazards of water supply pipe leakage, in order to attract attention and attention.
First, the cost of water supply increases
Water supply enterprises need to bear the direct costs of water production and transmission, and pipe leakage will lead to a further increase in the cost of water supply. Because in addition to the direct cost of water production and transmission, enterprises also need to bear the cost of pipeline maintenance due to water leakage. This not only increases the operational pressure on enterprises, but also may lead to an increase in water prices.
Second, water quality pollution
Leakage means that the pipeline is no longer a closed system, and when the water pressure inside the pipeline is low or when the water is stopped, the pollution outside the pipeline may enter the pipeline, resulting in water quality contamination. The phenomenon of shooting suction under special circumstances may also pollute the water inside the pipeline, posing a potential threat to the health of residents.
III. Ground Collapse
Water leakage from pipes will make the soil mobile, and if there is a drainage pipe nearby, the soil will continue to be lost, leading to the formation of a cavity under the ground. As the cavity expands, the ground may collapse, causing safety hazards.
Fourth, exacerbating water shortages in cities and towns
Water shortage is categorized into three types: water source type, engineering type and water quality type. But no matter which kind of water shortage, pipe leakage will exacerbate the water shortage situation. China is a general water shortage in the country, the annual national pipeline leakage of up to 10 billion tons of water, which is an alarming figure.
V. Reduced water supply pressure
Pipe leakage will lead to pressure relief, the user needs the water supply pressure will be reduced. And this pressure reduction is random, with the development of the city, the water supply pressure to ensure that it is more and more difficult, and pipeline leakage so that the network of water pressure management has become complex.
Six, water supply energy consumption increases
In order to deliver more water and ensure the water pressure of users, water supply enterprises have to consume more electricity. This not only increases the operating costs of enterprises, but also an additional burden on the environment.
Seven, water production capacity is too high
Pipeline leakage can become part of the water supply capacity into the actual effective water supply. However, because of the existence of leaks, this part of the production capacity is consumed. When the city needs to increase water supply capacity, but also need to expand capacity. This leads to water production capacity is much higher than the actual demand, resulting in a waste of resources.
VIII. Rising water table
In areas covered by water supply networks, the groundwater level becomes higher due to continuous leakage from the pipes. The higher groundwater level creates difficulties in the construction of underground works in the area. In addition, the problem of ground freezing in winter is also directly related to the groundwater level. Wherever there are underground pipes, the hard surfaces of the ground are convex and uneven.
Nine, reduce leakage investment increased
In order to control and reduce pipeline leakage, water supply companies need to take a variety of means, such as zonal metering, active leakage control, pressure control and so on. However, these means require continuous investment, and may need to be constantly adjusted as the leakage situation changes. Finding a balance between investment and leakage reduction is an ongoing challenge.
X. Impact on water price setting
The percentage of water leaking from pipes is critical in determining the final water price. If the actual leakage is much higher than the figure reported by the water supplier, the true cost will be hidden. This not only affects water price setting, but may also lead to waste of resources and environmental damage. Therefore, how to scientifically determine the percentage of water leaking from pipes is an issue that needs to be thoroughly studied and discussed.
Water leakage solution
When the water supply pipe leakage, water escapes under pressure will produce a noise, this noise will spread along the pipeline to both sides, or along the medium spread to the ground, water leakage detection instrument is to pick up the sound of this leakage, and converted to electrical signals, after the corresponding amplification and digital filtering, to determine the exact location of the leakage point. This is the traditional acoustic wave detection method for water leakage detection. In the area of 2m in diameter, the exact location can be determined directly by listening to the leak tube. The sound heard is the clattering sound of water flowing out of a ruptured water pipe.
Technicians use the leak detector, along the pipeline above the interval of 0.5 meters to select points, vertical pipeline parallel displacement of three points, large pipes using the "S" shape to select points, point by point to listen to, through the ground sound intensity, audio detection and analysis, to accurately locate. The key lies in the different leakage points, select different frequency bands, such as selecting the correct, can improve the leakage point positioning accuracy, reduce errors. Leakage point produces leakage sound frequency and pipe network rupture size, pipe diameter, pipe material related. Usually, the leakage sound of plastic pipe is a low-frequency signal, while the leakage sound of steel pipe or cast iron pipe is a high-frequency signal. Technicians in the leakage point positioning, must master the leakage point where the pipe diameter, pipe and other parameters, in order to correctly select the filter band, so that the
