Precise cable location before excavation. Reduce excavation damage, increase operational reliability and get a documented overview of your cable network with DWI A / S.
DWI performs professional pipe searches for water utilities, contractors and industry, where precise location of water pipes, service pipes and stopcocks is essential before excavation, renovation and design work.
We combine technical expertise, advanced methods and many years of experience with leak detection on complex supply systems – and we always work with a focus on precise troubleshooting and qualified decision-making.
Pipeline search and location of water pipes – before you dig
Professional cable tracing is a central part of the work to ensure stable supply networks and avoid damage to underground installations. When cables are located correctly, it becomes possible to plan excavation work, renovation and expansion of cable networks without unnecessary risks.
At DWI, we work specifically with pipe location and mapping of supply lines in both water supplies, technical installations and industrial plants. The tasks include, among other things, identifying water pipes, branch pipes, T-pieces, valves and stopcocks as well as verifying existing registrations in map and GIS systems.
We combine advanced measuring equipment, practical experience and understanding of utility operations, so that line tracing becomes not just a measurement - but a solid basis for decision-making.
Cable search before excavation and construction work
Inadequate registration of cables is one of the most common causes of excavation damage and unforeseen costs in projects. Systematic cable search before excavation work provides a much better basis for planning and execution.
It contributes, among other things, to:
- Reduction of excavation damage to water pipes
- Less risk in construction work
- Faster localization of existing installations
- Fewer disruptions in the supply network • Better coordination between the supply and the contractor
For water utilities and planners, professional pipe location means higher operational reliability and lower overall costs.
Advanced wire location
The choice of method for locating pipes depends on the type of pipe, material, depth, terrain and the quality of existing records. We use a combination of technologies to accurately locate pipes. This can include electromagnetic location, signal application, pulse generator, probes, ground-penetrating radar and analysis of existing drawing and GIS material.
In many cases, pipe tracing is combined with leak detection, so that both pipe routing and any leaks can be determined in the same effort.
Wire tracing in case of errors in GIS and inadequate registration
In many older supply networks, registrations do not fully correspond to reality. Lines may be offset in relation to map material, or previous rerouting may be poorly documented.
Here we work systematically with verification and updating of cable routes, so that the actual cable route can be documented and used in planning, operation and future projects. Precise mapping of cable networks provides a stronger basis for both renovation, sectioning and monitoring.
When is wire tracing used?
Pipeline tracing is used in many situations where knowledge of the location of pipes is essential for a safe project. Typical tasks include preliminary surveys before excavation, locating water pipes during renovation, mapping before establishing new connections, reviewing older pipe networks, and the interaction between pipe tracing and leak detection.
Common to these tasks is the need for a precise and documented overview of the underground installations.
Wire tracing in complex and critical installations
In hospitals, industrial plants and larger technical installations, errors in location can have major consequences for operation and safety. That is why we work with an analytical approach to cable location, where both the function of the installation and the operational conditions are included in the assessment.
This may include, for example, identifying supply and return lines, coordinating with technical personnel, and documenting the routing of the lines before intervention in the installation. In these environments, line tracing is often combined with technical analysis and leak detection.
Common to these tasks is the need for a precise and documented overview of the underground installations.
Professional lead generation – effort and rewards
Professional cable tracing not only provides clarity about where cables are located, it also creates a better decision-making basis for operation, renovation and investments in supply networks.
For many organizations, systematic wire verification means:
- fewer excavation damages
- more precise projects
- better documentation for authorities
- stronger management of construction work
- increased operational reliability
Cable tracing reduces the risk of excavation damage and enables excavation work to be planned correctly. When cables are located precisely, operational disruptions, additional excavation work and compensation claims are avoided.
Water pipes are typically located using electromagnetic equipment, signal application, probes or ground penetrating radar. The method depends on the type of pipe, material and the information already available.
Yes. Professional wire tracing is often used to verify or correct existing map material and GIS registration.
Yes. In many cases, pipe tracing is performed simultaneously with leak detection, so that both pipe routing and any leaks can be determined in the same effort.
