Client: Van Gelder B.V.
Koop Dewatering is supporting Van Gelder B.V. with the implementation of a high-voltage cable route between Hengelo and Almelo in the Netherlands. The aim of the project is to build a future-proof energy infrastructure. In order to carry out the construction work safely and efficiently, targeted groundwater lowering is required – for a stable and dry working environment.
Technical implementation:
- Installation of horizontal drains for controlled groundwater lowering
- Use of vacuum filters for effective water drainage
- Use of electric pumps for continuous dewatering
- Sustainable energy supply via a biogas generator from Bredenoord
Challenges and solutions:
During the project, we had to deal with complex soil conditions and a high groundwater table. Through the targeted use of modern dewatering techniques and close coordination with the client, we were able to react flexibly and ensure stable conditions in the excavation pit.
Result:
The groundwater lowering measures were successful and ensured a safe construction environment for the work on the cable route. Koop’s experience and sustainable approach made a decisive contribution to the smooth running of the project.
Our projects

Project TENP 3 – Los 4
In het kader van het TENP-3-project wordt in sectie Los 4 een 31 kilometer lang traject van de Trans-Europa-Naturgas-Pipeline (TENP) gemoderniseerd. Hierbij wordt de oude TENP-1-leiding vervangen door de nieuwe TENP-3-leiding om de leveringszekerheid en efficiëntie van het aardgastransport te verhogen.

Power line A-Nord – Section NRW1
As part of the expansion of the A-Nord power corridor, Koop Dewatering and its Special Projects Team are working on the NRW1 section. The approximately 73-kilometre section is part of the 300-kilometre overall route that is to transport wind power from the north to the industrial south of Germany - a key infrastructure project for the energy transition.
