API was recently contacted by a water utility to identify a possible leak on a 9 inch cast iron main. The client had accounted for a 2MLD loss and needed a clear resolution to the issue. API successfully surveyed the pipeline and identified an unknown branch connection. Due to the pipe location next to a bridge and river crossing, the pipe was encased in concrete so accuracy of an internal survey was paramount.
The branch connection was identified as a 6 inch leg, and was traced back to a buried valve and then isolated to resolve the issue.
API removes the guesswork with all pipeline issues, and has successfully surveyed thousands of pipelines throughout the UK. Using PIPA products has enabled us to increase our service range, and we now offer CCTV inspection and leak detection in all pipe sizes and materials.
