For example, the indication of the water pipe connecting your home to the mains could be simply a line or nothing at all on the plans. Unfortunately, you cannot see the utility services lead-in the property in detail on the utility plans. The property owner or a utility could have installed these services. Domestic services do not typically appear on BYD plans, mainly network services.ĭomestic services are utilities servicing the property and any privately owned pipes and cables within the property. Services on private property can either be domestic (terminate within the property) or network passing through the property. The subsequent problem of not knowing where services are, especially domestic installations, can result from owners not keeping records or not passing that information on when the property changes hands. Utility companies do not usually install on private property without the property owner’s knowledge or permission at the time of installation. It is reasonable to expect property owners to know what is on their property and their location.

Installation of most buried assets was before today’s accurate GPS/GIS technology.

In many cases, builders, contractors, or property owners install domestic connections,

The asset owner may not have done the actual installation.

Misplaced or missing marker posts or relying on old measurements being exact, which people tend to do, is hazardous therefore, in most cases, measurements for depths/alignments are not supplied by asset owners. Asset owners do not have ongoing visibility or control of the environment around their assets, so they do not know if changes have occurred. Also, misrepresenting property boundaries may occur, e.g., fences may not be in the correct alignment.

For example, some underground assets were installed 30 years ago or longer since then, surface levels could have changed up or down due to floods, agricultural practices etc.

Asset owners cannot record the exact measurements of depths and alignments because the ground profile could have changed since the cable/pipe was installed, rendering the measurements inaccurate and giving you a false indication of where it is.

Asset owners only record the general locations of their assets.
