zahnen water engineering performance

What is the present performance of my plant and how can I optimise it in line with future development?

These are key questions asked by our customers, the operators of industrial and municipal wastewater plants.

For us, it is not simply a matter of complying with statutory limit values, but above all reducing energy and maintenance costs, shortening project periods and the important subject of operational safety.

This is coupled with a need for innovation in the field of environmental and energy management along with the time factor associated with implementing new solutions rapidly.

Our integral approach, “zahnen water engineering performance”, allows us to accompany our customers nationally and internationally when optimising and modernising their sewage plants – and of course when building new installations.

Electrical engineering

The precise implementation of customer specifications is our watchword for tailor-made subcomponents, switch cabinets or individual switchgear in all sizes. Smooth and perfectly coordinated installation and implementation is ensured, even during ongoing operation.

Hardware and software are ideally tailored to the unique requirements of the project – from planning through to concrete customer documentation. Our experts in our in-house programming department can be relied on to deliver total quality.

Thanks to their extensive training, they always have the know-how needed for innovative technologies and control systems.


Optimal remote-maintenance technology calls for precision at all times and in all locations. That means we ensure all-round safety so as to minimise operational deployments. Plants are monitored from a central point, thus ensuring the early recognition of all types of system faults. Our solutions offer a free choice of data transfer: dedicated line, dial-up line, GSM or GPRS and DSL.

From alarm outputs through to control of the overall system, every solution is available in bespoke form. Additional extensions to the remote monitoring technology are possible without any problem. Even existing controls can be coupled with one another.

Mechanical engineering

Plants and machinery from a single source are our hallmark: special constructions, turn-key systems along with tailored subcomponents or conversions for special solutions that need to be implemented without interrupting production.

All this is possible thanks to our integral method of work, from planning through to installation, commissioning and maintenance. With our steel and pipe construction, we offer a reliable and outstanding spectrum of vertical integration in manufacturing. State-of-the-art CAE and CAD systems assist the expertise of our highly qualified technicians.

We are above all specialised in energy management, treatment plants, pumping stations, rainwater management systems and facilities for recycling sludge. We are also experts when it comes to the renovation and energy optimisation of existing plants.

Project management

We provide our customers with a highly professional project management that monitors the entire construction process of a facility according to a definite construction time schedule, both qualitatively and quantitatively. We guarantee implementation on-schedule and in accordance with the contract, handled by a responsible specialist as a direct contact. Competence from a single source.

The strengths of our experienced, flexible and highly trained project managers include informing, documenting, organising and coordinating. From the moment the project is launched through to the definition and implementation phase and finally project completion, all processes are perfectly coordinated. The fusion of knowledge segments and the division of the overall project into individual work packages is also professional in scope. For optimum effectiveness, our company is structured into separate disciplines for mechanical engineering and electrical planning. Within these disciplines, our project managers coordinate all tasks: software development, switchgear construction, fitting shops, installation and service along with documentation.

In particular, projects involving wastewater technology can benefit from our broad spectrum of engineering expertise.

Regular project meetings serve to permanently analyse all risks and opportunities so as to be able to offer our customers solution-oriented proposals. Because the efficient implementation and further optimisation of customer standards is our top priority.


  • On-schedule handling in line with the contract
  • Separate technical disciplines
  • Implementation from a single source
  • Broad spectrum of engineering expertise

Service & maintenance

Our 24-hour on-call service and employees who are always willing to contribute their technical and detailed knowledge mean that we are able to inspect, service and repair electrical machines and pumps made by almost all manufacturers around the clock.

Only a call is needed – rapid help for malfunctions by phone or on-site, prompt delivery of spare parts and, on request, installation in older plants are part and parcel of our customer service. Thanks to our experienced and outstanding team, we are also able to assist you in an advisory role when it comes to solving problems or replacing system components for optimisation.
