Leak detection<\/a> is a relatively new profession that arose in interaction with industrialization and urbanization in the 19th century. As people gathered in rapidly growing cities, the need for the supply of clean drinking water to consumers increased.<\/p>

Therefore, they resorted to a solution invented by the Romans before our era began: the aqueduct. Large earthed water pipes that could ensure a stable inflow of the important raw material.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In step with urbanization, the need for clean drinking water increased and the water supply network was expanded. But where there are smart solutions to important problems, there is usually also maintenance work.<\/p>

For water pipes do not last forever. There are holes in them from time to time, and even if you calculate the service life of the cable correctly, and make sure to replace it before the expiration date, there may be unforeseen factors that cause leaks to occur.<\/p>

At water mains close to the earth's surface, it is easy to see. Groundwater holes, ie collapse of foundation and surface, due to erosion, can occur.<\/p>

In some cases you will be able to see the water floating on the surface such as roads, sidewalks or natural areas, however, it is far from always certain that the leaks are visible.<\/p>

If the leak is deep, the water may not reach the surface. The deeper leaks can therefore remain untouched and significant amounts of water can be lost.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

When they started pumping groundwater up through large waterworks and keeping accounts of the water volumes, it was discovered that there was a large spill in several parts of the water supply network.<\/p>

That is, the amount of water pumped out of the waterworks was greater than the amount of water that reached the consumers. Therefore, methods began to be developed to easily and quickly locate any leaks.<\/p>

The different methods for locating the leaks are collectively called 'leak tracking'<\/a>, and that is what we deal with at DWI.<\/p>

The history of leak detection The history behind the profession Leak detection is a relatively new profession that arose in conjunction with industrialization and urbanization in the 19th century. As people gathered in rapidly growing cities, the need for a supply of clean drinking water to consumers increased. Therefore, they resorted to a solution that the Romans invented before the beginning of our era: the aqueduct. Large underground water pipes that could ensure a stable flow of this important raw material. Water supply and the need for effective leak detection As urbanization progressed, the need for clean drinking water increased, and the water pipe network was expanded. But where there are smart solutions to important problems, there is usually also maintenance work. Because water pipes do not last forever. They get holes from time to time, and even if you calculate the service life of the pipe correctly and make sure to replace it before the expiration date, there can be unforeseen factors that cause leaks to occur. With water pipes close to the surface of the earth, it is easy to see. Groundwater sinkholes, i.e. collapse of the foundation and surface due to erosion, can occur. In some cases, you will be able to see the water flowing on the surface such as roads, sidewalks or natural areas, but it is far from always certain that the leaks are visible. If the leak is deep, it may happen that the water does not come to the surface. The deeper leaks can therefore remain untouched and significant amounts of water can be lost. When people started pumping groundwater up through large waterworks and keeping records of the water volumes, they discovered that there was a large waste in several parts of the water pipeline network. In other words, the amount of water that was pumped out of the waterworks was greater than the amount of water that reached consumers. Therefore, methods were developed to easily and quickly locate any leaks that might exist. The different methods for locating leaks are collectively called 'leak tracing', and this is what we deal with at DWI. Read more about the history of waterworks and water distribution.
