  • Water Security – A Growing Issue with No Easy Fixes

    The issue of water security – access to enough quality water to make it possible to live safely – is a growing concern for many, just ask the communities of Flint and Corpus Christie. The problem is exacerbated when communities and companies come face-to-face over access to water supplies. Wouldn’t the nice idea be to share?  That’s met with disagreements as ...

  • Study of hydraulics and mixing in roof tanks used in intermittent water supply

    Roof tanks are common in low and middle income countries, due to the intermittent water supply. Their hydraulic and water mixing behaviour has not been studied. This paper presents the results of a study on mixing and water demand in roof tanks, based on physical and numerical models. Tracer tests were carried out on a real scale transparent wall laboratory model of a roof tank, and a ...

  • Robot Device for Pipe Inspection - Case Study

    In 2005, Pure Technologies (Pure), a provider of various structural monitoring and leak-detection technologies, set about to develop a pipeline assessment tool that could monitor and report on the condition of pre-stressed concrete cylinder pipes (PCCP) utilized in municipal water and sewer systems. The tool’s competitive advantage would be accurate assessment decoupled from the need to ...

  • Multiple-fault detection in water pipelines using transient-based time-frequency analysis

    Pipe faults, such as leakage and blockage, commonly exist in water pipeline systems. It is essential to identify and fix these failures appropriately in order to reduce the risk of water pollution and enhance the security of water supply. Recently, transient-based detection methods have been developed for their advantages of non-intrusion, efficiency and economics compared to traditional ...

  • Field Performance Testing for Pipeline Pumps

    Significant energy savings can be achieved by optimizing pump operating efficiency. Measuring the exact pump performance with crude oil under realistic conditions in the field is the first step towards improving the pump efficiency in the future. About 20 billion barrels of crude oil were transported through pipelines in 2015. Around the world, there are over one million kilometers of ...

  • Testing monolithic activated carbon adsorbers for in-line removal of organic micropollutants

    Anthropogenic organic micropollutants (OMP) occur along the whole urban water cycle including drinking water. Various OMP can be efficiently adsorbed onto activated carbon. In the present study a commercial monolithic adsorber (MA), originally developed for gas treatment, was examined for the removal of OMP from drinking water. As a promising advantage, the adsorber can be introduced into ...

  • Survival of pathogens in drinking water plumbing systems: impact factors and sanitation options

    The objective was to determine impact factors that would allow Pseudomonas aeruginosa and Legionella pneumophila to survive sanitation measures of household drinking water systems. Therefore, different disinfectant concentrations were tested under different operating conditions in close-to-practice experiments. Particular attention was paid to the viable but non-culturable ...

  • Flint Michigan Water Crisis

    The situation in Flint Michigan has been steadily deteriorating and there’s still some time before experts predict an end in sight. It’s reached the point where celebrities such as Cher and Pearl Jam have donated water or money for the affected towns and people living in them. But what exactly happened? In April 2014, it was decided by a ...

  • Accepted Inspection Methods of Process Sewers.

    During the process of refining there is discharge of hazardous waste, this coupled with aging pipeline infrastructure creates a potential where waste can leak into the environment posing catastrophic threats to life. Federal agencies such as the EPA are beginning to penalize refineries that do not take necessary measures of disposing their waste. These refineries are subject to ...

  • Quantitative pipe condition assessment with Pipe Penetrating Radar

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-ferrous (reinforced concrete, vitrified clay, PVC, HDPE, etc.) pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids ...

  • Water insecurity in Indigenous Canada: a community-based inter-disciplinary approach

    Water insecurity in Northern Indigenous communities in Canada remains a pressing problem, with multiple dimensions and health impacts. We carried out a case study of long-term water insecurity in the Southern Inuit island community of Black Tickle, Labrador, where there is no piped water and people rely on an under-funded potable water dispensing unit (PWDU) and unmonitored water sources. Our ...

  • A stochastic approach for extended partial blockage detection in viscoelastic pipelines: numerical and laboratory experiments

    Partial blockages in water pipe networks may contribute to large energy dissipation throughout the system and reduce service effectiveness for customers. In this paper, a recently developed stochastic model using transients for detecting partial blockages in water pipelines is tested and numerical and experimental case studies are presented. The model is a stochastic successive linear estimator ...
