From electrical planning in 2018 to commissioning in 2023

The Brienz WWTP is being newly built with a treatment capacity of 11,000 p.e. and a hydraulic capacity of 70 l/s. A sequencing batch reactor (SBR) process with three basins and an upstream rainwater basin will be used. The catchment area extends from Brienz to Axalp via Schwanden and Hofstetten.

STEBATEC has already carried out the electrical planning mandate and will now also implement the control and instrumentation technology, as well as the STEBATEC IT and network concept. Two TFPNA pneumatic flow controllers will be used for water distribution on two roads and for precise flow measurement. The pumping stations in the catchment area will also be renovated and equipped with ALLinONE control systems.

Customers: 4,200 inhabitants, various commercial enterprises
Length of mains network: 12,000m

The reliable discharge control for wastewater and rainwater

Pneumatic discharge control partially filled TF-PNA

Precise and easy to maintain throttle system for stormwater tanks and wastewater structures. The fast, almost self-cleaning and remotely controllable butterfly valve with pneumatic actuator is based on the flow measurement integrated in the system and limits the flow to an arbitrarily adjustable quantity. As long as the maximum flow is not reached, the flap remains open, while the flow measurement system measures precisely even when partially filled.

The alarm system for all cases: intelligent, flexible, user-friendly, modular

STEBalarm

Our alarm system STEBalarm is extremely versatile. For a wide range of industries such as retail and wholesale, food production, transport, sales, municipalities and cities, federal and cantonal authorities, industrial and manufacturing companies, banks, research institutes, energy suppliers, and power plant operators.

The process control system for sewage treatment plants and sewer network operators with the highest demands on safety, function and comfort.

ARAbella local process control system

Process control system for sewage treatment plant and sewer system Waste water plants become controllable with the process control system ARAbella in the simplest way. Via the intuitive user interface, the processes of wastewater treatment plants and outdoor structures can be operated quickly, easily and reliably. The operating status of the plants is clearly displayed at any time.

More functions. More comfort. More security.

ALLinONE control systems

Standard control with high individuality. Compact, simple and complete, ALLinONE controls and monitors ALLinONE pump stations and stormwater tanks. The control system is easily configured and requires no programming.

Individual automation for safe and efficient processes.

PLC control systems STEBAsmart

We support you with risk analyses, electrical, control and energy concepts and individual PLC programming in operation and in the realization of automation projects.

Secure and volume-reduced data transmission on the Internet and in networks.

STEBAnet Mobile and Fixed Network Telecontrol

Networking and remote control of automation systems STEBAnet mobile, fixed and leased lines are data communication systems for decentralized control systems. Measurement data and control information are recorded on site for backup purposes and cyclically sent in packets or compressed form to the database of the central process control system. STEBAnet communicates in a way that preserves data volume and establishes connections only when needed, for example when a user at the process control system is viewing live data.

Secure separation from the Internet. High level of comfort.

IT, Networks, Cybersecurity

We offer tailor-made, cost-optimized and future-proof solutions for an optimal demarcation of automation systems from the Internet, while maintaining access to the systems in terms of comfort and flexibility.

Electrical engineering with practical experience

Electrical planning

We are passionately committed to finding the optimal solution. In doing so, the trustful and close cooperation with the operator and planner is particularly important to us. Our company history began back in the 1960s; the large number of projects realised since then has provided us with extensive expert knowledge in industrial automation and electrical planning.
