Pipes and culverts that transport water are susceptible to failure as a result of cracking, the formation of holes and ineffective seals. Leakage from pipes can result in wetting or saturation of the surrounding ground which can initiate or worsen ground movement compromising the leaking asset further or putting adjacent infrastructure at risk. The BGS pipe leakage impacts map indicates where pipe leakage may initiate or worsen ground instability. It considers which, and to what extent, ground stability hazards may be adversely affected by water from leaking pipes.

The dataset is available in both a summary and a detailed format. The summary map contains a GIS layer that indicates the potential for leaking pipes to initiate or worsen ground instability. The detailed map contains the summary map described above, plus additional information indicating which ground instability hazards may be present is also included.

The map is created using the following datasets:

  • landslides – indicates where leaking pipes may initiate or worsen ground slippage
  • soluble rocks – indicates where leaking pipes may enhance the dissolution of rock/washing out of fines
  • compressible ground – indicates where leaking pipes may cause ground to compress
  • collapsible ground – indicates where leaking assets may cause the ground to collapse
  • swelling clay – indicates where leaking assets may cause swelling of clays and heave or lateral movement of the ground
  • running sands – indicates where leaking pipes may cause sand to run resulting in localised subsidence

This data is intended for asset managers who are responsible for assessing the condition of underground pipes and culverts. In particular, the data may help:

  • determine where leaks may cause ground instability
  • prioritise the repair of leaking pipes
  • assess the risk posed to infrastructure adjacent to water pipes should they fail and leak

A map entitled BGS corroded asset failure (ferrous) has been developed to complement this map and is available separately. It helps identify where corroded underground iron assets such as pipes, cables and building foundations may be at risk of failure due to ground instability. For more information see BGS corroded asset failure (ferrous) map.
