Hergiswil relies on a precise and maintenance-friendly measuring system

Clamp-on system as a replacement for existing measuring point

The Hergiswil water supply sought to procure a reliable and low-maintenance system, as the existing measuring installation was no longer providing reliable measured values. The solution in the form of a clamp-on measurement represents a high-quality yet cost-effective variant, which was installed.
WWTP V.O.G, La Verna, Ecublens, sludge treatment

Complete control replacement in 48 hours

The La Verna wastewater treatment plant in Ecublens FR has already completed several moderniza-tion phases during its almost 30-year collaboration with Stebatec.After this long period of trustful cooperation, the next major project is pending; the expansionof the sewage treatment plant from 22,500 population equivalents (PE) to 50,000 PE. To replace a control system in the ongoing clarification operation requires meticulous planning, ex-tensive preparatory measures and, ultimately, great commitment during the effective conversion phase.

Complete renovation of RB Eichbühl in Hilterfingen at Lake Thun

After a good forty years of operation, certain “signs of wear and tear” inevitably become visible. Therefore, the municipality of Hilterfingen decided to renew the infrastructure of the rainwater tank and pumping station Eichbühl as well as the pumping station Hünegg. In the search for a competent supplier, the ideal partner for the project was found in the company STEBATEC
Verbandskanäle Abwasser Region VKA Nidau/Biel

Completely web-based process control

For 15 years, VKA and STEBATEC, the German Association for Sewerage and Wastewater Treatment, have been working together successfully. The latest milestone is the introduction of ARAbella ONLINE: With the web-based process control system, processes can be controlled online via remote access. A management of the waste water quantities becomes possible.
Steam plant, Migros subsidiary ELSA Estavayer Lait SA

Condensate recovery and operation optimised

Estavayer Lait SA, or ELSA for short, operates one of the largest dairies in Switzerland in Estavayer-le-Lac. It processes 269 million kilograms of milk a year and employs around 600 people. It has been part of the Migros community since 2003 and is therefore essential for the food supply in Switzerland.
ARA Langnau: replacement of pumping station Marbach control system incl. connection to the ARAbella process control system

Configuring instead of programming with ALLinONE

ALLinONE control system was installed in just one day. The flexible configuration options make it possible to connect the outstation, including alarms, to the new PLS at WWTP Langnau without the need for complex programming.
ARA Region Oberes Simmental

Dynamic outflow for controlled inflow ARA Zweisimmen

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.
Under the Matterhorn

Electrical planner of the invisible sewage treatment plant

The Zermatt sewage treatment plant, which was built underground in rock caverns, was completely rehabilitated, almost doubling its biological treatment capacity. From the mandate of electrical planning and execution, a close cooperation developed, which today covers the entire measurement and control technology. Tasks Analysis of the existing plants and equipment Development of an overall EMSR concept Preparation of cost estimate Complete EMSR planning Site management: electrical installations, switchgear and control systems, measurement technology Initial situation / existing situation In 2008, Ryser Ingenieure AG, which was commissioned with the renovation of the Zermatt wastewater treatment plant, called in STEBATEC AG for the electrical planning.
Association for waste water treatment in Saint-Imier and surroundings, WWTP Villeret

Energy autonomy with photovoltaic and biogas plant

The Office for Water and Waste of the Canton of Berne obliges the operators of wastewater treatment plants (WWTP) to comply with the discharge conditions for treated wastewater into water bodies even in the event of a power failure. Therefore, the operators of the WWTP must install an emergency power supply that can guarantee the operation of the essential plant components.
