Factsheet for enquiries

What ist the BIL?

The nationwide information system for pipeline research (BIL) was founded in 2015 in order to reduce damages to underground pipelines caused by construction works by providing legally compliant pipeline information. In cooperation with the Federal Network Agency, the online portal makes it possible to centrally depict nationwide information on pipeline routes. 
In the meantime, approximately 100 companies from all energy supply sectors are participating in the central online platform for pipeline research and thus enable a simple and efficient research process for those planning construction measures. 
Further information is available on the BIL website:
