Referenzart: Partially filled pneumatic discharge control

City of Winterthur (CH), Wastewater storage basin Dättnau

ALLinONE and pneumatic discharge control TF-PNA prevent sewerage network overload

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.

ARA Winznau; from flow measurement to dynamic sewer network control

STEBATEC equipped the entire sewer network with PNA dynamic flow controllers and flow measurements, which were integrated into the ARAbella process control system via STEBAnet and connected to the INKA sewer network regulation system. Since 2016, the entire ZAO sewer network has been dynamically regulated.
Precision measurement & control technology for the Reutlingen municipal drainage system

Combination of transit time difference measurement (LDM) & pneumatic discharge control (PNA) for automated regulation of stormwater overflow basins

True to its motto “Only the best for water”, Stadtentwässerung Reutlingen (SER) strives to operate its facilities using the latest technology in a sustainable, environmentally friendly and economical manner. For this reason, a new flow measurement system has now been installed at the rainwater overflow basin at Willy-Brandt-Platz, which ensures greater measurement and control accuracy.
Reinhalteverband Mühltal & Region Böhmerwald, A-Auberg

Dynamic sewer system control significantly reduces discharge quantities

The Reinhalteverband Mühltal & Region Böhmerwald in Upper Austria consists of 24 municipalities, looks after around 1.000 km of sewer, 18.000 sewer shafts, 300 pumping stations, 60 storm waterbasins and 6 sewage treatment plants. Despite its size, however, the drainage system reached its limits. The individually operated storm waterbasins, for example, relieved the load rigidly into the recipient in the event of overload.

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.

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.
