Yes, or something similar[1]:

A few of the more efficient grounding electrodes for buildings and structures are:

- Metal Underground Water Pipe

- Metal In-ground Support Structures

- Concrete-Encased Electrode (also known as “footer ground” or “Ufer ground”).

- Ground Ring

As mentioned this is particularly important for telecom and similar systems which have signal wires going literally through the ground.
