	Buried utilities including pipes, drains and culverts enable the transport and supply of potable water, sewage and stormwater, and the conveyance of streams in channelized watercourses. Such assets are prone to leakage through cracks, holes and ineffective seals, resulting in wetting or saturation of the ground surrounding the asset. The failure of assets can occur for a wide variety of reasons including corrosion of the asset, ground movement (e.g. swelling clays or frost heave), pressurised flow or human-induced disturbance for example. Once failure has occurred, water leaking from assets can have a negative effect on the surrounding ground potentially causing leakage-induced ground movement.
