  • Diseases That Biological Water Treatment Can Prevent

    Biological water treatment is essential because drinking contaminated water can cause illness. There are many types of contaminants, and the most common are human and animal feces, agricultural run-off, and chemicals. These contain pathogens, which cause water-borne diseases. These pathogens can quickly spread via different methods. Here are some of the most common diseases that can be ...

  • Advantages of Advanced Water Treatment Solutions

    Various advanced water treatment solutions are available for households as well as all types of facilities and industries. Water filtration provides users with valuable benefits that many don’t realize yet. Here are some of the advantages of water treatment solutions like an arsenic treatment system. Improved Water Quality A good arsenic filtration system ...

  • Efficacy of chlorine, chlorine dioxide and ultraviolet radiation as disinfectants against plant pathogens in irrigation water

    Abstract A number of disinfection treatments are available to treat irrigation water to reduce the risk of plant disease. However, limited published studies had compared the efficacy of disinfection treatments on a range of plant pathogen species, on their various life stages and in different water qualities. In this study, propagules (spores, mycelium, cells) of eight plant pathogens ...

  • Aqueduct Water Risk Framework

    Awareness around the physical, regulatory and reputational water risks to companies and their investors is on the rise; and robust, comparable and comprehensive data is needed to help assess these water-related risks. In response to this demand, the World Resources Institute (WRI) Markets and Enterprise Program developed the Aqueduct Water Risk Atlas, a comprehensive and publicly available global ...

  • Water-Related Business Risks

    Water scarcity, pollution, climate change, and other problematic global water trends pose major challenges to businesses now and will continue to do so in the years ahead. The following article summarizes relevant concepts and provides a non-exhaustive overview of case studies, existing risk management tools, and global players. ...

  • Water-related climate risks

    Future changes in the hydrological cycle may have important impacts on the society, e.g. with regard to flood risks, water availability and water quality. Although climate observations do not show consistent global trends in the hydrological cycle despite of the global warming in the past century, strong regional and seasonal changes are possible. Even if for some regions the mean hydrological ...

  • Are our Water Systems at Risk?

    Assessing the Financial Sustainability of BC’s Municipal Water and Sewer Systems Reliable water, sewer, and storm water systems are essential to public health, a clean environment, and a strong economy. But British Columbia’s systems may be at risk – aging infrastructure, growth, strengthened regulations, seismic risk, and climate change are driving the need for ...

  • Risk management for water supply pipes

    In this paper, the risk of water supply systems as a combination of hydraulic analyses (consequence) and failure probability of pipelines based on the actual condition is discussed. On the one hand, a stepwise closing of pipelines calculates the influence on customer's supply which represents the importance of a pipe. On the other hand, based on existing failure statistics, age and material ...

  • Water risk to business is no small drip

    At the World Economic Forum in Davos two weeks ago, I was struck by how often the issue of water risk was raised by business executives. As the global economic turmoil is receding, many CEOs and global leaders are turning to other threats—and water is high on the list. For the second year in a row, water crises were named among the ...

  • International waters: identifying basins at risk

    Despite the growing literature on water and conflict in international river basins, little empirical work has been done to bolster common conclusions which are so widely reported. In order to address this gap, we set out to assess all reported events of either conflict or cooperation between nations over water resources during the last 50 years and to use these events to inform the identification ...

  • Antiviral pandemic risk assessment for urban receiving waters

    An 80% metabolic conversion of the Tamiflu® pro-drug (oseltamivir phosphate, OP) to its metabolite oseltamivir carboxylate (OC) and a high excretion rate combined with poor removal at sewage treatment works (STWs) means that potentially high STW OC emissions may occur in receiving waters. A risk assessment approach undertaken within the River Lee catchment in North East London indicates that ...

  • Risk analysis of seasonal stream water quality management

    Seasonal discharge programs, which take advantage of temporal variation of stream assimilative capacity, are cost effective. However, these seasonal discharge control programs should not increase the risk of water quality violations. A method is presented to estimate the allowable pollutant loads under both seasonal and non-seasonal discharge control programs for a single discharger that ...

  • A model for risk minimisation on water resource usage failure

    We present a framework for solving the strategic problem of assigning transboundary water resources to demand centres under uncertainty in the water exogenous inflow in the reservoirs and other segments of the basin system along the time horizon. The functional to maximise is the probability of satisfying different targets on the stored water and different demands over a set of scenarios. A ...

  • Cascade vulnerability for risk analysis of water infrastructure

    One of the major tasks in urban water management is failure-free operation for at least most of the time. Accordingly, the reliability of the network systems in urban water management has a crucial role. The failure of a component in these systems impacts potable water distribution and urban drainage. Therefore, water distribution and urban drainage systems are categorized as critical ...

  • Risk-based planning for water recycling in an Australian context

    Australia has seen an unprecedented proliferation in large scale water recycling schemes since the late 1990s. This has been driven by a recent decade of drought, policies to encourage water efficiency in new homes and buildings in urban areas, and to reduce pressure on rain-fed water supplies by replacement with alternate water sources in rural areas. Underpinning these drivers are principles ...

  • A risk management approach for trunk water mains

    The supply of water from source to customer relies on a pipe network system graduated from large pipes at sources, down to small pipes servicing houses. The larger pipes in this system termed Trunk Mains, represent the prime assets of water systems. Failure of trunk mains can cause loss of service to large populations for extensive periods and significant damage to property and social fabric. A ...

  • Risk and Integrated Water Management (GWP, 2002)

    This paper attepmts to address different risk categories that water managers and water users are faced. It argues that risk managment is a distributive issue that cannot be treated solely as a technical matter best handled by experts. It involves the allocation of wealth and welfare between water sectors, ...
