Concerns with verifiability

As verifiability is an important concept in OSM, buried features may not comply with this principle.
Highway/railway/waterway tunnels should normally be verifiable since they are often visible or accessible by car, train or on foot.
When it comes to underground pipes or cables, markers may indicate the existence of a feature which is not visible from above ground. Such features may be considered sufficiently significant for the underground element to be added to OSM.

You should refer to Verifiability guidelines page at every survey you make of underground equipment.
