The plastic channel is by far the most common way to protect the pipes and cables that are underground, both in households and gardens, and in commercial facilities, such as roads or play. While clay pipes are often used in some major commercial projects, it is equally likely that larger plastic pipes can be found in today's construction sites. The location of the channel is correctly located, there are many benefits to an underground facility. Tubes primarily provide protection from ground movements and cables or pipes from animal activities, but warns of future installation of a pipe or cable, often preventing costly damage and restoration work. At the same time, it makes it much easier to replace existing cables or even more, without the need for larger earthwork.

Although water pipes should be installed at depths regulated by the strict guidelines, other services are very different – in fact, some other rule of thumb.

The black wire is normally used to carry electric current. The cable in the black wire is low (less than 250V) or medium (less than 500V). Red tubes have larger voltages (greater than 500V) and never near the surface.

The yellow channel contains a gas pipe. This tube is usually made of polyethylene and the gas is placed on the inlet side of the gas meter.

Blue pipeline is suitable for drinking water. In most cases it would be a MDPE (medium density polyethylene) plumbing tube.
