Exact flow measurement with water analysis

…the wastewater volumes in the free-flow area upstream of the treatment plants would be accurately recorded and water analysis data determined. Two independent measuring points were to measure the flows accurately and stably, while a third measuring point was to be additionally equipped with online analysis measurement with data transmission.

From safety inspection of the steam boilers to component replacement and commissioning – one contact partner

As the supervising company, we continuously monitor the condition of the plant. We check all safety-relevant parameters every six months and suggest maintenance work if necessary.

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.

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.

Aproz Sources Minérales SA

Hot water plant Aproz Mineralquelle; New safety control reduced the amount of work required

The old safety control system was designed in BOSB 72 (operation without constant supervision), which required extensive checks at least every 72 hours. The new control system was designed in BOME (operation without manual intervention), which significantly reduced the amount of work required for monitoring.

New measurement for accurate data

LDM 500 for the municipality of Ägeri in the catchment area of the Water Protection Association region Zug

The Zugersee – Küssnachtersee – Ägerisee Water Protection Association has a new LDM measuring station in the Schmittli structure below Ägeri with a digital transmitter that provides precise measurement data. Thanks to the proven technology, the measurement is extremely low-maintenance and therefore saves costs.

LDM partially filled Nominal diameter 400

“The LDM is a very intuitive system. The transmitter provides the information I need at a glance” says Hans Stucki, plant manager of WTTP Langnau, who wanted a precise and reliable measuring device to limit the amount of water transferred and to measure dry weather quantities for billing.

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.

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.
