API recently completed 3.5 km live CCTV and acoustic inspections of water mains in and around Stirling, Scotland. The client had seen a severe depletion in hydro output due to a potential pipe implosion or leak.
The result findings were very informative; the pipelines were still in a good general condition with no leaks identified, however a 50 metre section of pipe implosion was identified on a mid-section of pipeline.
All surveys were undertaken whilst the pipes continued to function under normal operating flow and pressure, with no loss of hydro output experienced by the client during the inspection process.
