Without regular inspection and maintenance, pipeline networks can rapidly fall into disrepair, with partial or complete blockages due to cave-ins, tree root ingress or the accumulation of solid components, e.g. silt deposits or the growth of fat-bergs.
These can potentially lead to flooding and severe consequences for the asset holder including loss of reputation, incurred responsibility for property damage, legal action and high financial penalties.
Current preventative measures include CCTV inspection combined with water jetting, both of which are time consuming and extremely costly.
Tellus Utilities have developed an acoustic system, The ORCA (Obstruction Recognition and Condition Assessment), that can identify the existence, location and even the size of a blockage, in air (gas) filled pipelines.
