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.
From electrical planning to installation and commissioning.

Full renewal of a stormwater basin for the City of Grenchen

The City of Grenchen is currently renewing itsfour stormwater basins constructed in differentyears. The first such basin to be refurbished isthe second-oldest and the biggest of the four basins built in 1975 ad named after the publicswimming pool nearby. The basin had a numberof structural defects but most pressing were therectification of issues of operating the basin andproblems of work safety.
Electromechanical equipment for the Ipsach rainwater basin

General repairs to the rainwater basin in Ipsach

The Association for Sewers and Waste Water (VKA) in Nidau is responsible for the waste water treatment plants from Port to Moeringen on the southern banks of Lake Bielersee. The Association manages several rainwater basins and pumping station. The Ipsach rainwater basin was built in the early 1990s. The unique feature is that this is a rainwater basin in a connected system.
NEAT; Consorzio TAT Tunnel Alptransit Ticino

Gotthard base tunnel

When ready, the Gotthard base tunnel will be the world’s longest railway tunnel. After a successful initial installation phase in 2006, additional installations for measuring the flows of water from the construction site and the entering well water are required in the section from Faido towards Sedrun in 2009.In the Faido – Sedrun section, the water flows in the drai-nage ducts after the Piora syncline and in the Borel zone are to be measured, the measuring data transferred to the tunnel portal by a suitable data transmission system and processed automatically by customized computer software so that the measuring results can be submitted to the supervisory authorities and the geologists as fully analyzed data sets.
For more process control with less effort - a state-of-the-art wastewater treatment plant.

How ARA Weinland optimizes its processes with smart controls

The ARA Weinland is setting new standards in wastewater treatment: With the implementation of the modern ARAbella process control system from STEBATEC, the control system of the wastewater treatment plant has been fundamentally modernized. The plant now benefits from more flexible, more transparent and safer process control.
Pacovis wastewater treatment plant, Sassenberg

Increased performance through dynamic SBR control

During the production of marinades for meat and herb mixtures, the Pacovis company in Sassenberg (D) produces wastewater with a high concentration of COD (chemical oxygen demand). In order to relieve the local wastewater treatment plant, an SBR (Sequence Batch Reactor) treatment plant was installed, which pre-treats the waste water and reduces the COD concentration to below 800 mg/l before it is discharged into the public sewage system.
ASTRA Federal road office (CH)

Mountain water measurement Belchentunnel

The Federal Roads Office (ASTRA) relies on STEBATEC for the collection of precise hydro-measurement data as a basis for the expansion of the Belchentunnel, both for the measurement technology and for data transmission and monitoring.
Syndicat des Eaux de Tavannes et Environs, WWTP Loveresse

New electrical distribution without interruption of operation

Loveresse’s wastewater treatment plant (WWTP) treats the wastewater of the municipalities in the catchment area of the Syndicat des Eaux de Tavannes et Environs with a total population equivalent of around 7000. Like all WWTPs in the Canton of Berne, it is subject to the condition imposed by the Office for Water and Waste of the Canton of Berne that the conditions of discharge of the treated wastewater into the receiving watercourse be complied with even in the event of a power failure.
WVS Wasserverbund Seeland AG, ground water catchments and water tower Gimmiz

New process control and regulation technology

Last year, STEBATEC was allowed to replace the existing process control system and the control software of the water supply system and implement extensive process optimizations. Energie Service Biel/Bienne, Energie Seeland AG and the Seeland Water Supply Association are partners of the Wasserverbund Seeland, which supplies drinking water to around 30 communities and 100,000 people in the Bernese Seeland.
New construction of wastewater treatment plant Brienz
PLC controls, ARAbella process control system, STEBalarm, Pneumatic discharge control TFPNA

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

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.
Rehabilitation of WWTP and special structures during operation

Niederbipp WWTP renovation; overview thanks to new process control system

Together with Ryser Ingenieure AG from Berne, the STABATEC team was able to complete the renovation of the wastewater treatment plant, as well as the replacement of the control and measurement technology in the external structures, and the integration of a process control system within one year during operation.
ARA Meiringen

Process control system, maintenance plan and STEBalarm

The Meiringen waste water treatment plant tre-ats the waste water of the municipalities of Mei-ringen, Hasliberg and Schattenhalb and – nitrogen reduction included – is designed for about 13,000 population equivalent. The old process control system had become outdated and the frequency of failures increased.
