Dynamic outflow for controlled inflow ARA Zweisimmen

ARA Region Oberes Simmental

The Region Oberes Simmental sewage treatment plant treats sewage of the municipalities of Lenkand Zweisimmen. The largest inflow passes through the Galgenbühl storm overflow basin, other inflows originate in the area of Mannried and the Grubenwald pumping station. During rainy spells the inflow from Mannried often causes overload conditions in the sewage treatment plant. Separation of the rainwater in Mannried and active throttling in the Galgenbühl stormoverflow basin should solve the problem. Needed was a dynamic control system on the basis of the volumes measured as well as better measuring equipment and control of the sewage treatment plant. To this end, the hydromechanical throttle in the Galgenbühl storm overflow basin was replaced by a pneumatic outflow controller so that the inflow to the sewage treatment plan was adaptable to the hydraulic conditions irrespective of the weather.

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.
Resistant electrical engineering in wet, corrosive, explosive and aggressive environments
As a licensed electrical installation company, we offer the highest installation quality with special products and equipment for durable and trouble-free installations.

For more than 30 years, STEBATEC has been one of the leading companies in project planning and realization of reliable, precise and integrated solutions in the automation industry. Our project team consists of automation, electrical and software engineers, design and mechanical engineers, project managers as well as fitters and service technicians.
Proud of our craft!
Day after day, STEBATEC fitters honour our craft by carrying out installations of the highest quality that are a joy to the eye of the professional.
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.
Preventive maintenance, servicing, spare parts management and many other services to ensure the reliability of automation systems.
Whether it is the cleaning of systems or the replacement of mechanical wear parts, the monitoring of functions, the calibration of measuring instruments or software updates, whenever customers need support in the ideal operation and maintenance of a system from our company, we are available with our services.
