The sewerage network of the city of Winterthur consists of over 600 km of private and public sewerage. It collects wastewater from Winterthur and 11 surrounding municipalities and directs it to the ARA Hard. During heavy rainfall, the sewerage system below the Dättnau stormwaterbasin was overloaded even though the Dättnau stormwater basin above was almost never filled.
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.
Waste water association of Meilen, Herrliberg and Uetikon am See
The Meilen waste water association on Lake Zurich had two measuring stations set up to collect data on wastewater charges at an industrial company. Because the wastewater flows from pressure pipes, the construction had to be adapted to the situation. The scope of supply includes a carefree package: Flow measurement Measuring chamber Control and lift for lowering Data transmission to the sewage treatment plant
Electromechanical equipment for the Ipsach rainwater basin
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.
