McBreen Environmental provide expert Integrity Testing services right across Ireland. A pipeline integrity inspection is often specified in site environmental licences such as IED, IPC and Waste Licences. Many such licences in Ireland also require pipeline integrity inspection of storm water and foul water (i.e. domestic effluent) lines.
Leaks from oil pipes, effluent pipes and pipes carrying oil and chemicals can lie undetected for years. This thereby causes local soil contamination and possible contamination of surface and ground water. The potential clean-up cost could run into millions. Therefore integrity testing is vital.
Pipeline integrity inspection methods
McBreen Environmental can undertake pipeline integrity testing & inspections in full accordance with EPA and other regulators’ guidance. Test methods include hydrostatic testing and air pressure testing and pigging. Where the air pressure of hydrostatic test shows that the pipe leaks, a CCTV inspection identifies the cause of the leak.
Pipeline CCTV inspection
In some case sites have arranged CCTV inspections of their pipelines instead of air pressure or hydrostatic testing. However, a CCTV inspection will not determine if a pipe is water tight. The only way to prove water tightness is by an air pressure or hydrostatic test.
Assessment of above ground pipelines
Where pipes run above ground, leaks from valves, flanges and other fittings cause ground and surface water contamination. Often the EPA require an assessment to determine whether retention of leaks from valves and other fittings is required. McBreen Environmental carry out these assessments and have undertaken such assessments for large pharmaceutical plants. We often find that either no retention is required as the site is fully bunded, or minimal remediation work is required.
In addition to pipeline integrity assessment, McBreen Environmental also offer advice on Tank, Manhole and Bund integrity assessments and firewater integrity assessments.
