New wastewater treatment plant in Brienz with control and instrumentation technology from STEBATEC

PLC controls, ARAbella process control system, STEBalarm, Pneumatic discharge control TFPNA

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


Products in use

The reliable discharge control for wastewater and rainwater
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
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.
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.
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.
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.
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.
