We set up an Urban On-line Water (UOW) modelling system in Hangzone Sonnenberg (HZS) – the third largest and most complex pressure zone of Zurich. The UOW consisted of on-line hydraulic and water quality models interconnected with the hydraulic and water quality sensors in the network.
Almost all inflows and outflows of the supply zones in the Zurich water System (ZWS) are measured in the supervisory control and data acquisition (SCADA) system. However, there are only a few water meters within the zone’s network and pressure meters are installed in some shafts. Not all of them are integrated in the SCADA system. As such, there’s a dearth of information about the behaviour and the actual hydraulic and quality conditions in the network.
WVZ wanted to know more about its network, in order to be able to detect changes in future water quality variations within the network. The solution: an on-line system of hydraulic and water quality models interconnected with hydraulic and water quality sensors in the network.
To help achieve this goal, WVZ started a pilot project together with us, to set up a UOW system in Hangzone Sonnenberg (HZS) – the third largest pressure zone of Zurich.
This will help WVZ gain actual information about the hydraulic conditions, the mixing of water from different sources and the water quality in the network. In so doing, WVZ hopes to improve the system’s overall performance (in terms of economy, service level and safety), through an increased ability to control and manage issues related to water flow, quality and security.
