User guide for the Pipe Leakage Impacts map

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. This user guide describes the Pipe Leakage Impacts map, which has been developed by the BGS to indicate 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 leaking from pipes. This map is intended for asset managers who are responsible for assessing the condition of underground pipes and culverts. In particular, the data may be useful for water companies or councils who need to determine where leaking pipes (or other sources of water) may impact ground instability, so that repairs, or other action, can be prioritised.
