Water and waste water pipe

Do you require info about water and waste water pipes?

We keep a cadaster of the water and waste water pipes in Graz. This is a plan of the entire supply network (water pipe cadaster) and the public disposal network (sewer cadaster).

For this purpose, all new constructions and conversion are already measured in the course of the execution of the construction. Existing facilities are also measured concurrently. All facilities are administered in a digital geo information system (GIS) and kept up to date.

Extracts from the cadaster

Extracts from the cadaster can be obtained via our pipe information system or directly from our employees at Wasserwerkgasse 11.

• Data about the domestic sewer facilities are on display for inspection by the respective property owner at the building and facilities authority of the city of Graz.
• Data on hydrants and on extinguishing water can be requested by e-mail.
• If you have any queries or more detailed questions on the waste water and water pipes, please also feel free to contact us by telephone.

Our waste water fees and charges at a glance:
