Detailed description

Disturbances in the drainage system can arise from various causes, such as

If the problem is in the public sewage system, you can report it to the responsible authority so that measures can be taken to rectify the problem.

 

Information

Prerequisites

Please note

You can use the transfer shaft or cleaning opening on your property to check whether the wastewater is still draining properly and whether the problem is actually in the public sewage system. A transfer shaft is usually located on the property line. If there is development along the property line, the cleaning opening is located inside the building (for example, in the basement or utility room).



If the affected drainage system is located on your property, you are responsible for rectifying the problem yourself.

If the problem is in the public sewage system, there will be no costs for you.
