Con­nec­tion

  • We are the hub and the contact person for the sewer system connection (approval for the connection, production of the branch pipe, consultations, etc. ..).
  • We are the representation of the city of Graz as the sewer system company and in the event of responses to the suitability of building plots
  • We also ensure the testing of domestic sewer systems and new connections to the public sewer system

 

What needs to be noted with a connection:

  • Every person who wants to construct a new building in Graz has to clarify the waste water disposal in the course of the construction procedure as a preliminary question. If a public sewer is available, a connection is mandatory.
  • This mandatory requirement for a connection also applies with the new construction of sewers for existing buildings.
  • Holding Graz Water Management division grants consent to the connection to the public sewer system.
  • Every person who discharges his or her waste water into the public sewer system must pay a one-off contribution to the sewer system. This contribution is also usually incurred with extensions to buildings.

The determination of the basic data (date incurred, number of WCs and determination of space) is carried out by the city of Graz buildings and facilities authority. Billing will be done by the municipal administration department for municipal charges.

The sewer fees can be found here!
