WHG-certified contractor with its own workshop
ZIMMERMANN Engineering is a specialized contractor certified under the Water Resources Act (WHG) and operates its own workshop in Gütersloh. We install and repair systems and system components where the safe handling of water-polluting substances poses special technical challenges. Our range of services includes work on LAU facilities for storage, filling, and transshipment, as well as on HBV facilities for production, treatment, and use.

Plant and Piping Engineering
Our workshop handles project-based manufacturing, assembly, and repair work in the fields of plant and piping engineering. This includes, in particular, work on:
- Pipelines and Pipeline Systems
- Containers and collection systems
- Pumps
- Fittings
- Components of LAU and HBV systems
The design is tailored to the technical requirements of each project. Before work begins, we work with you to assess the condition of the system, determine the scope of work, and establish the necessary framework conditions.
Construct and Maintain Wastewater Treatment Plants
Another area of focus is the construction and repair of wastewater treatment plants. Depending on the specific task, we also perform cleaning and decommissioning work on existing facilities. The individual measures are tailored to the facility, the substances present, and operational requirements.
Partial Repair of Retention Areas
We perform coating work for the partial repair of retention areas. Materials and methods are selected on a project-by-project basis and according to the intended application. The goal is to restore or maintain the retention function of the area in accordance with the specified technical requirements.
Joining Operations Following Approved Process Tests
In addition, we perform adhesive bonding work as part of approved process validations. The selection and application of the joining process depend on the materials to be joined, the intended use, and the project-specific requirements.
