Abstract: Recent research has developed more accurate methods to estimate the peak demand for premise plumbing design in residential buildings. The improved accuracy produces lower design flow rates, leading to a reduction in pipe ...

Abstract: This research investigated the dynamic effects of iron bacteria–formed biofilms and associated material accumulation on pipeline head loss and roughness for the Salt Interception Scheme (SIS) in South Australia. Two case ...

Abstract: Water main breaks in city areas can cause significant economic loss, interrupt traffic, and result in negative publicity for utilities. The South Australian Water Corporation (SA Water) has taken a proactive approach to ...

Abstract: Uncontrolled pipe breaks are a challenge for water utilities all over the world. This paper describes a technique that enables pipe cracks to be identified at an early stage before they become uncontrolled breaks by utilizing ...

Abstract: The propagation of pressure waves in water pipes is frequency dependent, which leads to these waves experiencing a frequency-dependent wave speed and attenuation, resulting in wave dissipation and dispersion. The effect ...

Abstract: Timely pipe break and burst detection and localization are important for proactive management of water distribution systems (WDSs). This paper presents a novel timing-based method for fast localization of hydraulic transient ...

Abstract: Research undertaken in the last two decades has demonstrated that hydraulic transient pressure waves, the phenomena behind water hammer, can be used as a tool for noninvasive and nondestructive condition assessment of long ...

Abstract: Hydraulic transients (water hammer waves) can be used to excite a pressurized pipeline, yielding the frequency response diagram (FRD) of the system. The FRD of a pipeline system is useful for condition assessment and fault ...
