Leak detection in Central Denmark
The sandy soil swallows the evidence
In many places in Central Denmark, the soil is so sandy that a leak never leaves a trace on the surface. The water seeps vertically down and is gone – no wet spot in the grass, no bubbling asphalt. A pipe can stand and empty itself for years without anyone seeing anything other than a consumption figure that won't do the trick.
Therefore, the task cannot be solved with the eyes. DWI A / S performs leak detection in Central Denmark with acoustics and measurement technology that finds the leak through the ground instead of waiting for it to appear.
Many waterworks, few hands
Central Denmark is the region of waterworks. A large part of them are run by boards and volunteers who look after the works in addition to everything else – and who have neither the equipment nor the time to hunt for a leak themselves. For them, DWI functions as an external leak team: We know the network from the last visit and speak in solutions rather than technical terms.
Size never determines whether the task is interesting. A small plant with a large water loss is at least as busy as a large supply.
Leak detection in Central Denmark – also outside the city signs
Agricultural properties often have long underground pipes from the property to stables and irrigation systems, and a leak there is typically only discovered on the water bill. Our leak detection also covers these types of private pipes: We follow the pipe through the field and mark the location of the leak so that the repair can be completed in one go.
For utilities and larger networks, we offer planned reviews where the zones are taken in sequence and the water loss is recorded along the way.
Leak detection in Central Denmark: one day's measurement can save weeks of digging
The methods are the same, regardless of whether the pipe is located under a main street in Herning or a grass field near Karup – but the emphasis changes. On long, undisturbed stretches, correlation measurement is superior: Two sensors on opposite sides of the leak measure the arrival time of the sound, and the position is calculated with great accuracy, even over considerable distances.
Where the sound does not carry – in plastic pipes or at low pressure – we push a harmless tracer gas through the pipe and scan the terrain from above. And if the pipe is located in a different location than the papers say, we first determine the route with wire search.
The frost reveals the network's weak points
Every winter, cold spells put pressure on the power grids, and old joints give way when the ground is worked. These breaks rarely come at an opportune time. Data loggers in the network, it detects increased noise from an incipient leak long before it develops, and with The HydrantAI platform Overall, the operations manager will be notified automatically – even on Sunday mornings in February.
Leak detection in Central Denmark reverses the math
For a smaller waterworks, each lost cubic meter takes up relatively more of the accounts, and NRW – water that is produced without ever being invoiced – gnaws at an economy that is already tight. Precise localization changes that quickly: When the excavator only has to dig in one place, the savings are already there at the first discovery.

Buy the equipment or learn the craft
DWI A / S sells and leases professional search equipment as an authorized distributor of, among other things, Gutermann – with service that keeps the instruments ready for measurement. If the plant's own people can take the first round themselves, the basic course At DWI Leak Academy, we put the methods into your hands through theory and exercises on the test track.
We operate throughout the region, including Herning, Viborg, Silkeborg and Holstebro.
Yes. We first locate the pipe's route and then the leak location – without digging more than the one necessary hole.
As suits you: single tasks in case of suspicion or a fixed agreement where we review the network at agreed intervals and keep the history up to date.
Yes, call the emergency number. +45 70 23 98 98 – we can often be there the same day.
That's where it's most important. Sandy soil hides the leak from the eye, but not from the acoustics and trace gas.
Preferably before winter, when experience shows that frost stresses weak joints - and otherwise when consumption figures give reason to do so.
