  • Failure risk assessment in water network in terms of planning renewals – a case study of the exemplary water supply system

    In the paper the issue of failure risk assessment in water supply system (WSS) was presented. Problems of water supply network failure constitute a crucial issue in waterworks practice. The results of the analysis were obtained on the basis of real data from water network operation. Attention has been paid to the problem of risk assessment in the context of risk acceptance criteria. An example ...

  • Knowledge-based planning of groundwater treatment trains for an efficient drinking water supply system in urban areas

    This paper presents knowledge-based planning of the most appropriate treatment schemes for drinking water supply (DWS) systems, jointly applying statistical tools and experimental tests. Milan City was chosen as the case study, its DWS system being composed of more than 20 DWS units, widespread in the urban area. First, multivariate statistical techniques (factor analysis and cluster analysis) ...

  • New Jersey Water Use Exceeding Supplies

    When people think of water scarcity, arid regions such as Israel, Egypt, and Southern California may come to mind, but the availability of clean, potable water may also be endangered in unexpected places, including New Jersey. Residents in some areas of the Garden State are using “tens of millions of gallons” more water than the ...

  • Salting icy roads affects water supplies

    It’s basic chemistry: Saline water’s freezing point is much lower than fresh water’s, which can help keep ice from forming on roads. To reduce winter accidents, municipal and state workers often apply salt and other compounds to icy roads, because if not accidents start to happen and people end up in need cash in emergency. Unfortunately, this may have unintended consequences ...

  • Assessing future water supply and demand in a water-stressed catchment after environmental restrictions on abstractions

    The Ali Efenti catchment is a rural upstream subcatchment of the Pinios river basin in central Greece. The average annual precipitation in this subcatchment is relatively higher and groundwater recharge is relatively faster than in the rest of the river basin. Yet, seasonal water shortages occur due to the rapid increase of water abstractions in the summer months, mainly for crop irrigation. ...

  • Impact of extreme climate events on water supply sustainability in Egypt: case studies in Alexandria region and Upper Egypt

    Water resources in Egypt have become stressed due to changes in climate patterns. Egypt is characterized by two seasons, a mild, wet winter and a hot, dry summer. In recent years, many areas have become vulnerable to the impact of extreme climate events. The impact of these events on water supplies has become more pronounced. This study states that there is a tangible impact of extreme climate ...

  • Decentralized water treatment and local water shortages

    MIT researchers conclude that alternative approaches to water planning can alleviate urban water supply issues quickly and inexpensively Urban areas around the world are expanding rapidly as the global population increases and people are moving to cities at a fast pace. This puts a strain on current infrastructure, including water treatment plants. Add global warming and increasing drought ...

  • Water mixing in waste lagoons

    Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three ...

  • Singapore a model for effective water management

    Singapore continues to be a model of effective water management as more and more countries begin experiencing water scarcity. To some, the Asian city-state (which occupies an area roughly a quarter the size of Rhode Island) may seem an unlikely beacon for water efficiency. But, to achieve water security and self-sufficiency, residents have been helping leaders meet national water management ...

  • Report: California’s Reliance on brackish water desalination to increase

    Years of drought in California may result in the state becoming more reliant on brackish water desalination, according to the Pacific Institute. In “The Cost of Alternative Water Supply and Efficiency Options in California,” the Oakland-based nonprofit research institute looks at the costs of potential water supply sources and other economic factors. The institute states: ...

  • U.S. utilities increasing water reuse investment

    Decreased technology costs are prompting more municipal water utilities in the United States to invest in new water reuse infrastructure. In fact, a new forecast projects more than $18 billion in water reuse and desalination projects are on tap in 17 states, according to Bluefield Research analysts. Although water scarcity is a conventional driver for this type of project, the analysts say the ...

  • Water is a key concern on Earth Day 2017

    Although the official focus of this year’s Earth Day is environmental and climate literacy, water is still very much a key concern for participants holding events across the United States — and around the world. A need for clean water for future generations was the impetus for the original event, and the need to protect water is no less important today. Earth Day was established in ...

  • Report: Energy industry sustainability efforts could save water

    Utilities, the oil and gas industry, and governments all use a lot of water. A recent report from Barclays Bank and the Columbia Water Center says that innovation by these organizations could help them become more efficient and sustainable, reducing their use of fresh water to better protect the valuable resource. According to the analysts, a focus on water management best practices could ...

  • A strategic framework for sustainable water resource management in small island nations: the case of Barbados

    Physical scarcity of freshwater is often given as the reason for water shortages, but it is usually its management that can either create or resolve the problem. This will be illustrated by the case of Barbados. The water management issues are typical of many small island states, some of which are particularly vulnerable to water scarcity, especially in the context of climate change. Barbados ...
