Wasserversorung Zürich (WVZ)

Update increases performance significantly

The Wasserversorgung Zürich (WVZ) has been working with Geocom products since 2006. With the update project implemented in 2020, the 280 employees of the WVZ will benefit from new functionalities and significantly improved performance. Thus, all requirements for a future-proof network documentation are fulfilled.

WVZ is responsible for supplying drinking water to all households and businesses in the city of Zurich and 67 other municipalities. They benefit from the large capacity of the WVZ, which can supply water even in the hottest summer thanks to Lake Zurich. The WVZ facilities include four waterworks, a control center, 21 reservoirs, 29 pumping stations, 1570 km of water mains, over 1200 wells and 7000 hydrants.

The GIS department of the WVZ consists of 3 GIS specialists, about 12 GEONIS editors and several GEONIS viewers. They ensure the daily updated documentation of the entire pipeline network. It supports the various GIS user groups in internal projects and processes with the creation of applications, statistics or plans. The WebGIS reaches all 280 employees of the WVZ.

The Solution

Geocom as a company of VertiGIS supported the GIS department of the WVZ in the update project. In particular, we prepared scripts for the update of the water industry model and assisted in the update of the database. This meant that the entire project could be completed more efficiently and, thanks to a high degree of flexibility, in a shorter period of time.

Added Value

The update of GEONIS to version 2017.2 was necessary for several reasons: The desire for higher performance in general and especially at the start of a new project was at the top of the agenda. In addition, the switch from Esri Object ID to Global ID offers significant advantages, especially when integrating third-party systems. All users should also benefit from the improved structure, e.g. in the table of contents, and more clarity in the water solution. This makes working with Geocom solutions and thus VertiGIS even easier. For the communication with third-party systems and external users, the current software packages of Microsoft SQL-Server and ArcGIS can be used again with the update.

Customer Testimonial

“The update project was completed to our complete satisfaction. Thank you to all involved at Geocom.”
