The high density of water supply networks, particularly in urban areas, makes proper marking of their layout especially important. The solution here lies in marking the water supply networks with detectable and non-detectable warning tapes. Such tapes provide an early warning regarding the existence of a water line, which prevents accidental damage to the water supply network. It is possible to add a stainless steel insert to the tape, which ensures an easy location of the network.

This solution also applies to sewerage and drainage. As in the case of water supply networks, the marking of district heating networks gains in importance in urban areas. To prevent accidental damage to district heating networks, green-white and purple, detectable and non-detectable warning tapes are being used. For easy localization of the network, tapes with stainless inserts can be used.
