  • Three separate water leaks located over a distance of 826m using the AQUASCAN TM2 - Case Study

    Introduction Locating leaks on large diameter water mains can be very difficult due to poor sound propagation and increased distances between fittings that can be used to perform correlations from. For a correlator to highlight a potential leak each sensor must be able to receive the signal from that leak. ...

  • A resilience-based prioritization scheme for water main rehabilitation

    Water supply infrastructure in the United States is one lifeline system that is in dire need of huge financial investments to counter pipeline deterioration while keeping up with increasing demands and reliability goals. With decreasing financial resources available to state and local governments, effective decision-making tools for pipeline prioritization are becoming an increasingly integral ...

  • 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 ...

  • Iterative LP water system optimal operation including headloss, leakage, total head and source cost

    Linear water balance optimal operation models are common with relative short solution times but suffer from a lack of certainty whether the given solution is at all hydraulically feasible. Introducing hydraulic headloss, water leakage and changing pump energy consumption, effect the resulting system optimal operation but also create a non-linear problem due to the convex relation between flow, ...

  • Applications of discriminative flow pattern analysis using the CFPD method

    Several applications of a new method for flow pattern analysis called the Comparison of Flow Pattern Distributions (CFPD) are presented. This method allows the user to compare flow patterns of a supply area and distinguish consistent from inconsistent changes in them. The so-called consistent changes are mainly caused by modifications in the characteristics ...
