Several hamlet on the territory of the municipalities of Burgdorf and Kirchberg had no link-up to the central sewer system. To improve this unsatisfactory situation, the intention was to collect the residential wastewater from the different hamlets in pump wells and then dispose of it into the public sewer systems. On the basis of the available connections, totally six smaller pumping stations and one main pumping station were needed.
The 1000 inhabitant community of Diessbach in the Swiss canton of Berne obtains its drinking water from ESAG in Lyss and operates its own reservoir for the water supply. Because the previous components were obsolete and there were no spare parts left, the community had the control system renewed by STEBATEC in order to increase operational safety.
Operating cost divider according to stationarily measured external water quantities.
An association of twelve municipalities in Wallis was looking for a just cost allocation solution to account for the high foreign water content in the waste water entering the treatment plant. The measuring system installed now records the different outflows and thereby rewards those municipalities that already have installed a separation system.
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.
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.
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.

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.

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, Ener-gie 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.
