  • Leak detection by inverse transient analysis in an experimental PVC pipe system

    Leakage reduction in water supply systems and distribution networks has been an increasingly important issue in the water industry since leaks and ruptures result in major physical and economic losses. Hydraulic transient solvers can be used in the system operational diagnosis, namely for leak detection purposes, due to their capability to describe the dynamic behaviour of the systems and to ...

  • Proactive Leak Detection of Oil & Gas Assets Can Improve Worker Safety

    According to the U.S. Energy Information Administration, there have only been 4 new refineries built in the last 20 years on US soil. Those 4 refineries have a combined capacity of These complex, engineering amusement parks must be properly maintained if they want to continue to not only be operable but also profitable. One aspect of proper maintenance and environmental stewardship is ...

  • Mancomunidad de la Comarca de Pamplona (MCP) Identifies 4 Leaks Using Inline Leak Detection

    Around the world, leaking water pipelines represent a major resource and financial loss for utilities. It is estimated that in some places, Non-Revenue Water exceeds 50 percent. In terms of financial losses, the World Bank estimates that NRW costs utilities worldwide about US$14 billion annually. By reducing these losses by half in areas with the highest NRW, it is estimated that US$2.9 billion ...

  • Locating Leaks for Cooling Water Systems

    This article illustrates how to locate leaks on cooling water systems in loud, industrial environments like Nuclear or Coal power generating plants without digging or putting anything inside the pipeline.  Infrared-Energy Pattern Analysis (IR-EPA) works on all pipeline sizes and all pipeline materials because it identifies the water outside the pipeline instead of listening for leak noises ...

  • Making Every Drop Count: Unitywater uses leak detection as a foundation for condition assessment

    It stands to reason why many utilities respond to leaks only after they receive a call about water gushing from a street or a complaint from a customer about a damp basement, or other signs of visible leakage. Human nature reflects the adage that is often easier to respond to an ...

  • 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 ...
