Zero leakage approach

We are renowned for our industry-leading approach to leak detection, having delivered some of the largest trunk main leak detection projects in the UK and abroad, for clients such as international water undertakers and industrial users.

Our state-of-the-art technologies accurately detect the smallest of leaks and air pockets in a pipeline. Utilising pre-existing access points for deployment and removal of equipment wherever possible, leaks can be identified, assessed and quantified without causing disruption to the service.

Working in partnership with utilities and industry, our techniques save time and money as well as conserving water that would otherwise be unaccounted for and lost. The detailed data that is gathered during inspections enables leak repairs to be prioritised immediately following the survey.

SmartBall®

SmartBall® is one of the world’s most trusted inspection technologies. It is a free-flowing (rolling) inspection tool that can be deployed for long distances, while the pipeline remains in service, thereby avoiding customer disruption.

Sahara®

Sahara® is a highly accurate tethered inspection tool used for pin-pointing leaks and carrying out pipeline condition assessment in real time while the pipeline is in service. The tool can be used in potable water trunk mains, raw water mains, waste water rising mains and sewers.

PipeDiver®

PipeDiver® is a free-swimming, high-resolution pipe inspection tool for large-diameter pipe inspections. Not only does it operate while the pipeline remains in service, it is capable of inspecting the condition of 40km or more in a single deployment.

Successful results

In over 20 years of using the Sahara leak detection technology, WRc have found over 5000 leaks on 5000km of water mains surveyed; this equates to one leak every for 1 km surveyed. However, we are often asked to carry out annual repeat surveys on the same mains, detecting new leaks for repair each year. Closer analysis of the data shows that on average 1 leak is detected for every 500 metres of pipeline being surveyed for the first time.

The size of any leak detected is estimated and reported allowing clients to prioritise repairs. Leaks ranging from a few litres per hour to several hundred cubic metres per hour have been detected. Small leaks may be monitored using annual surveys to check that they are not getting worse; large leaks are pin-pointed for immediate, emergency repair.

Covering a range of networks

Our flexible leak detection technologies can be used to inspect a growing number of assets:

  • Raw water pipelines
  • Trunk mains
  • Distribution mains
  • Service pipes
  • Gravity sewers
  • Pumped rising mains
  • Industrial networks

Sahara has enabled Thames Water to reduce trunk-mains losses by 65Ml/d. Conventional methods would not have detected leaks with such confidence, nor located them with such accuracy.

Using Sahara we have been able to reduce our entire water importation by 3.5%. The savings afforded paid for the survey works in just eight months.
