  • What Causes Water Main Leaks?

    The number one cause of water leaks today and moving into the future will be the aging infrastructure. “A large part of the US public water system dates back to the years shortly after World War II, therefore, a significant amount of buried infrastructure is at or very near the end of its useful life.” – Qureshi & Shah, Journal AWWA. When aging infrastructure is combined ...

  • Detecting leaks through AMR data analysis

    Automatic meter reading (AMR) provides real-time consumption data, enabling to collect a huge amount of information about daily, even hourly, consumptions. It is then easy to assess lost volumes on the network, using supplied volumes information. However, because of the multiple components of water losses, the metering and calculation inaccuracies, the occurrence of new (detectable) leaks is ...

  • 3D model evolution of a leak based on GPR image interpretation

    This paper presents some aspects of the time propagation of underground water leakage in controlled laboratory conditions using a drilled polyvinyl chloride (PVC) pipe and interpreting ground penetrating radar (GPR) images. GPR pre-processed images are interpreted for easy identification and extraction of surfaces and volumes of water leakage. Finally, the temporal evolution of a water leak is ...

  • Tackling Non-Revenue Water by Identifying Small Leaks

    Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to ...

  • `XuperPhos brazing alloys save customers` money,` says Castolin Eutectic European expert

    What are the advantages of the newly developed Castolin Eutectic XuperPhos brazing alloy range? Arantxa: The main advantage of the new XuperPhos range is that we avoid the problem of boiling during the heating process. And this way, we prevent leaks from appearing in the joints. We have metallographics showing that after the brazing process with a standard product, we can find pinholes in ...

  • Metropolitana milanese reduces water loss on critical steel pipeline

    Assessing the condition of buried water infrastructure can yield a variety of outcomes that are difficult to predict. Sometimes, they even seem random. The common belief that the age of a pipe determines its condition is rarely correct – in many cases, a newer main can be in worse condition than one twice or three times as old. Instead, operational, environmental and installation factors ...
