Business Administrator EFZ & Electrician EFZ

The Start of Our Apprenticeship at STEBATEC AG

I, Rojhat Aygan, recently began my apprenticeship as a business administrator (EFZ) at STEBATEC AG. Even in the first few days, I had the chance to meet many new people and was warmly welcomed into the team.

THIS IS STEBATEC

Partner for process automation, measurement technology and plant engineering

With around 130 employees, STEBATEC positions itself as a key driving force in the European water and wastewater market. All shares in our company are held by employees, thereby reinforcing our partnership-based approach.

STEBATEC was founded in 1990 and has continued to develop ever since. Today’s structures are based on a long history of entrepreneurial development: Its roots now stretch back to 1913, when the firm Züllig was founded, from which STEBATEC Züllig AG emerged in 2024. In addition, the former Scheidegger Fernsteuerungen AG – STEBATEC Trinkwasser AG since 2020 – brings its long-standing history dating back to the 1960s to the group.

Experience and expertise are what set STEBATEC apart. We are 70% a software company, complemented by services in the fields of engineering, product manufacturing, installation and after-sales service.

STEBATEC products automate water supply systems, sewage treatment plants, sewer networks and industrial heat generation plants. From electrical design through IT, control and process control technology to flow measurement, machinery and sensors: STEBATEC has proven itself as a partner for process automation, plant engineering and turnkey solutions.

Feedback

Comments of our customers

With the new water quality monitoring station, we have an up-to-date overview of the quality of our springs at all times. Detecting changes early on gives us added peace of mind and allows us to act quickly if necessary.

Peter Marugg

Brunnenmeister

CH-7250 Klosters

STEBATEC guided us through the entire modernization process as a competent and reliable partner. We particularly appreciated the comprehensive support, the practical collaboration, and the quick, solution-oriented assistance—even when faced with unexpected challenges. Today, we benefit from a more efficient, safer, and more flexible facility.

Christian Marti

Head of Technology & Maintenance Schweizer Zucker AG

CH-3270 Aarberg

For us, the key advantages were the ease of installation, the ability to provide accurate data at low flow rates, and hygienically sound measurement. The clamp-on technology can also be seamlessly integrated into existing water supply systems.

Georg Matt

Managing Director

FL-9492 Eschen

The renovation and technical upgrade of the Ländte wastewater pumping station marked a major step toward the future. The modern control system and user-friendly touch panel not only make operations more efficient but also safer. We were particularly impressed by the well-thought-out implementation of safety measures in the storm water basin area. Our collaboration with STEBATEC was constructive, reliable, and solution-oriented throughout the process.

Ueli Meili

Municipal Worker / Facilities Manager

CH-3652 Hilterfingen

The modernization of our boiler system and the introduction of REbella have made our steam generation significantly more efficient and flexible. Thanks to automation and improved transparency, we can respond more quickly and plan maintenance in a targeted manner. We have also increased safety standards and reduced operating costs.

Reinhard Kalbermatter

Master locksmith Société Suisse des Explosifs (SSE)

CH-3900 Gamsen

Thanks to the new control system, we clean the wastewater as needed, which saves energy and improves quality. For us, this is a big step into the future.

Beat Anderegg

Sewage treatment plant operator

Ebnat Kappel, SG

With ARAbella, we have not only received a new control system, but also a platform that supports us throughout the entire operation. The integration of maintenance planning, documentation and process analysis not only makes our work easier, but also more efficient. We can make informed decisions because all the relevant data is available in one place.

Ueli Schwander

Wastewater treatment plant Marthalen

CH-8460 Marthalen

«We are delighted with the modernisation of the boiler safety and control systems by STEBATEC. The seamless integration of the new systems without any interruption to production was particularly impressive. The high-resolution HMI touch panel and the extended maintenance intervals have significantly optimised our operating processes. We are extremely satisfied with the professional implementation and the excellent customer service»

Jorges Simoes

Infrastructure manager Hugo Reitzel SA

Stebatec impresses us with its innovations and good service. We particularly appreciate the co-operation with Stebatec's motivated employees, who work with us persistently to find the best solution.

Fabrice Bachmann

Managing Director GVRZ

CH-6314 Unterägeri

STEBATEC Trinkwasser AG proved to be the ideal partner with its expert advice and support during implementation. Replacing the MID measuring point with a clamp-on system ensures the daily availability of precise measured values over a period of 24 hours.

Peter Wigger

Fountain master

«The specialists at STEBATEC AG supported us at every point in the project and always fulfilled our wishes with top performance and solutions tailored to us. We are very satisfied with the project execution and look forward to further cooperation with the STEBATEC team.»

Christian Zurbrügg

Foreman FBB Kalksandstein AG

CH-3053 Münchenbuchsee

«The cooperation with STEBATEC and Saacke has worked smoothly at all times. The new control can be configured easily and quickly via the modern 7 inch HMI touch panel and the monitoring and optimisation via our process control system works excellently. We thank STEBATEC and Saacke for the high-quality order processing.»

Fabian Bron

Head of Maintenance EMSRT | BEIE IWB

CH-4002 Basel

«We were looking for an automation company that does not subordinate our concerns but leaves the freedom of design to the customer - the PCS ARAbella from STEBATEC offers unrestricted access for process optimisation for operators who want it. Menu-driven and safe.»

Michael Baumann

WWTP Brienz wastewater treatment manager

CH-3855 Brienz

«We are exited about the robust LDM flow measurement and the intuitively operable transmitter. It provides me with all the relevant data precisely at a glance.»

André Eggenschwiler

Operator at ARA Falkenstein

CH-4702 Oensingen

Stebatec is very customer-oriented and takes our concerns seriously. The partially filled stationary flow measurement with the ultrasonic transit time difference measurement has proven itself. It delivers precise measured values (1-3% accuracy) and maintenance is also extremely simple thanks to the open design.

Michael Kasper

General Manager wastewater treatment plant Kloten/Opfikon

CH-8152 Glattbrugg

«The cooperation with the STEBATEC team works very well. They always help me quickly and competently. I am happy to have a contact person for all electrotechnical, IT and control technology questions!»

Daniel Disler

Head of Niederbipp depot

CH-4704 Niederbipp

For us, the Scheidegger damper actuators is the best solution. For all our applications in the primary system with pipes up to DN 1000mm, we always have the same mechanical and electrical interfaces. The fact that even the largest dampers can be operated with a drive of only 24VDC allows us to operate our systems safely even in the event of a power failure without expensive UPS systems.
