Leak detection in Randers
The town by the Gudenå River has enough water - even that which shouldn't be there
Randers is built around water. That's precisely why a leak can hide well here: In a city with a river and fjord nearby, moisture in the ground is not automatically an alarm signal, and a leaky pipe can work undisturbed for months.
DWI A / S performs leak detection in Randers and the rest of Kronjylland. We locate the break with such precision that the contractor can put the shovel in the right spot the first time.
How do you detect a leak that no one can see?
Most often, it is the numbers that tell the story. When consumption is measured during the network's quiet night hours, when almost no one is drawing water, the curve should be flat – if it is not, water is leaking somewhere. Nighttime consumption that creeps up month after month is the classic first sign of a hidden leak.
Other times, the network reports falling pressure or a water bill that is no longer consistent. Regardless of which signal you have captured, we can translate the suspicion into a precise position in the network.
Emergency or planned leak detection in Randers
A visible breach requires immediate action, and DWI offers emergency response – call the emergency number +45 70 23 98 98, then help is on the way. Quick location means less water waste and a much smaller hole in the road.
Planned leak detection in Randers takes place at a different pace. Here we arrange a review of the network that suits your operation – as a one-off task or as a recurring agreement where water loss is monitored and documented over a number of years.
Leak detection in Randers – from the entire supply zone to one point in the road
One leak detection works like a funnel. First, the zone where the water loss is located is identified. Then the operator listens with a ground microphone and a hand-held monitor, and the correlator finally calculates the exact position based on the sound measured at two points on the pipe – after which the intersection can be painted on the asphalt.
Is the leak silent? Some do, especially in plastic pipes and at low pressure. In those cases, we fill the pipe with a harmless tracer gas and scan the surface until the leak reveals its location.
The whole process requires that you know where the pipes actually lie. If the map material does not match reality, we locate the pipes with wire search, before listening begins.
What is going out of the accounts in the meantime?
Every cubic meter that is pumped out but never reaches a meter is produced and printed out into the network – paid for by the utility without a penny in return. The industry calls it NRW, Non Revenue Water, and for many networks it is one of the items that can be reduced most quickly when leaks are first precisely located rather than being dug for on a whim.

Surveillance makes the next leak a small matter
Data loggers in the network listens around the clock and registers when the noise picture changes. Are they connected to The HydrantAI platform, all the network data is collected in one place, and you are automatically notified of deviations from normal operation. A leak discovered in its first week costs a fraction of a break that is allowed to develop.
We also carry out tasks throughout Eastern Jutland, including Randers, Silkeborg, Horsens and Viborg.
Who we help in and around Randers
The nature of the task depends on who is calling. The utility company needs zone reviews and documented water loss reduction, while the waterworks with few people in operation often need a quick, concrete location. We help real estate and industry when consumption increases without anyone being able to pinpoint the cause.
We are nationwide and operate throughout Central and Eastern Jutland - including Viborg, Silkeborg, Hobro and Aarhus.

Would you like to know more yourself?
DWI sells and leases professionally equipment for leak and wire detection and is responsible for the ongoing service. We are an authorized distributor of, among other things, Gutermann and helps put together instruments that fit your network. If you also need to get the skills in place, DWI Leak Academy offers basic course in wiring and leak detection with both theory and practical exercises.
We respond as quickly as possible and in many cases can be there the same day. The emergency telephone number is +45 70 23 98 98.
Contact us with your consumption figures. A deviating night consumption or pressure drop is usually enough for us to plan a targeted search.
Yes. We adapt the method to the pipe material and pressure – older cast iron pipes and newer plastic pipes simply require different approaches.
The price depends on the scope of the task and the conditions in the network. Call or write and we will assess the task specifically.
Yes, with data loggers and the HydrantAI platform that automatically alerts when operations deviate from normal.
