Turnkey custom solution for the expansion of PWN Heemskerk, Netherlands
Prefabricated cable ladders – for an efficient and future-proof water treatment plant
To ensure a continuous supply of sufficiently clean drinking water, PWN is expanding its water treatment plant in Heemskerk, in the Netherlands.











As part of this major project, and on behalf of Croonwolter&dros, OBO Bettermann is making a significant contribution to the cable infrastructure by delivering a complete turnkey solution based on intelligent prefabricated Cable ladders .
From calculation to mounting
When it comes to complex projects in industrial and supply technology, careful preparation is crucial. This is why the most efficient method for realising the Cable support systems was examined at an early stage.
For this project, OBO Bettermann developed various prefabricated cable ladders tailored exactly to the installation routes and the space available. The components were produced in advance and delivered ready to mount. This enabled faster and more efficient work on-site while minimising costs due to errors.
Custom cable infrastructure
The cable ladders form the backbone of the cable infrastructure in the new plant. They were installed in technical rooms, shafts and under false floors, with each section being designed specifically for the respective conditions on-site.
One unique aspect of this project was the use of unusually wide cable ladders, measuring 800 mm and 1,000 mm in width. These dimensions are rather uncommon and required tailored mounting solutions in multiple places.
For example, OBO Bettermann developed special support profiles for the pump room to be able to mount two 800 mm Cable ladders safely above one another. In another area, a suspended support structure was created to integrate two 1,000 mm cable ladders into the floor structure seamlessly.
These technical challenges were what made this project unique. By incorporating creative ideas during the execution phase, practical solutions were developed tailored perfectly to the conditions on-site.
Turnkey service
The strength of a turnkey approach lies in the overall package. From planning and preparation, to prefabrication and logistics, all the way to support on-site, OBO Bettermann works with the installer towards a common goal: an efficient construction process that delivers a reliable end solution on schedule. Thanks to an intelligent combination of prefabricated solutions and careful preparation, mounting time and work on-site was minimised, allowing installers to respond quickly to unforeseen situations during mounting.
Collaboration between the engineering and mounting teams enabled the implementation of tailored solutions – even for complex structures – without compromising on quality or jeopardising the schedule.
Working together for a reliable drinking water supply
With the expansion of the water treatment plant, PWN is investing in a reliable production site for the future. OBO Bettermann is proud to support this socially significant project with innovative turnkey solutions and tailored prefabrication.
We would like to thank Croonwolter&dros for the enjoyable and highly effective collaboration and for the trust placed in OBO Bettermann over the course of the project.
