API was recently contacted by Anglian Water to identify and locate a leak under a busy motorway crossing. Due to the high traffic volume location, the survey was undertaken during a night shift and was a huge success. The survey was achieved by using the PIPA Pipepod LS system, a new and unique tool for pressurised leak detection and also mains tracing.
The survey was previously undertaken by another contractor using 2 different types of advanced correlators with no leak identified. The success of the survey enables the client to close a smaller section of the road during repair works, and also undertake a much reduced size of excavation.
