Thyssengas Netzauskunft

Pipeline information

Web portal

The presence of underground supply systems is generally to be expected for construction projects. In order to fulfil your duty to enquire, pipeline information is to be obtained before beginning the work.

In addition to design and construction companies as well as representatives of public interests, you as a private person must also consider the fact that there may be supply systems on your property.

Die Thyssengas GmbH is a member of the national information system for pipeline enquiries BIL eG. BIL provides comprehensive cross-sectoral online information.

You have the option to make your enquiry directly through the BIL web portal at

The use of the BIL pipeline enquiry is free of charge for you and enables you to quickly and easily formulate your construction enquiry directly online. Your benefit: Your enquiry directly reaches all of the pipeline operators available via BIL. If we are not responsible for the area in your query then you will immediately receive negative information through BIL.

If Thyssengas systems are affected by your construction project then you will be informed of any necessary security measures and conditions
