Traditionally when new underground utilities were added to an area where other
utilities had already been installed, like a water reticulation network, and the new utility
was to pass by or cross the existing one the party doing the installation would run a big
risk of damaging the existing utility. This risk would greatly be reduced if the exact
position of existing utilities were known.
Another problem is detecting water leaks in services because of the natural flow of
water. (Flowing through the path of least resistance.) This causes excavations to be
large in comparison to what is needed for the repair of the leak.
The aim of this treatise will be to investigate different technologies available to discover
leaks and/or the positions of underground water, storm water and sewer reticulation
