  • A service-oriented approach to assessing the infrastructure value index

    Many national and regional administrations are currently facing challenges to ensure long-term sustainability of urban water services, as infrastructures continue to accumulate alarming levels of deferred maintenance and rehabilitation. The infrastructure value index (IVI) has proven to be an effective tool to support long-term planning, in particular by facilitating the ability to communicate ...

  • Smell no evil: Copper disrupts the alarm chemical response in a diadromous fish, Galaxias maculatus

    Fish, at all life stages, utilise olfactory information in the decision‐making processes essential to survival. Olfaction is a sensitive sensory process, and toxicants within urban aquatic environments can have destructive or depreciating effects. In this study, we exposed Galaxias maculatus, a native fish commonly found in urban waterways throughout south‐eastern Australia, to one of five ...

  • Detecting anomalies in water distribution networks using EPR modelling paradigm

    Sustainable management of water distribution networks (WDNs) requires effective exploitation of available data from pressure/flow devices. Water companies collect a large amount of such data, which need to be managed correctly and analysed effectively using appropriate techniques. Furthermore, water companies need to balance the data gathering and handling costs with the benefits of extracting ...

  • Predicting ‘very poor’ beach water quality gradings using classification tree

    A beach water quality prediction system has been developed in Hong Kong using multiple linear regression (MLR) models. However, linear models are found to be weak at capturing the infrequent ‘very poor’ water quality occasions when Escherichia coli (E. coli) concentration exceeds 610 counts/100 mL. This study uses a classification tree to increase the accuracy in predicting ...

  • Instrumented Safety: The right balance

    The different functional safety guides and standards such as IEC61508/511, which impose formal schemes for the safety instrumented functions (SIF), have brought significant safety gains to the process industry over the last 30 years. Still, we can observe a drift in the application of those standards, which often leads to increased costs, loss of operability, and, more worrying, a false ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • Statistical approaches for analyzing customer complaint data to assess aesthetic episodes in drinking water

    Customer complaints and concerns about their drinking water quality provide valuable information for assessing potential risks when utilities routinely analyze these data. This research presents strategies to evaluate complaint patterns for diversity and frequency of descriptors and to apply exceedance frequencies to evaluate when the complaints were indicative of a water quality problem. Mean ...
