  • Economic regulation of the water supply industry in the UK: a game theoretic consideration of the implications for responding to drought risk

    Droughts have tested the water supply companies in UK over the past decade. This paper employs game theoretic modelling to test hypotheses regarding the implications of price cap regulation for resource and supply security. We present an empirical analysis of drought management by ten water companies in UK as a basis for formulating formal games. These games are estimated. The game between the ...

  • Water Woes — And Winners

    Businesses can barely use the word “water” today without also adding “risk,” “crisis,” “shortage” or another similarly miserable modifier. With a 40 percent shortfall predicted by 2030, it’s no wonder the World Economic Forum has pegged ...

  • Aruba promises the best water

    Aruba is a Caribbean Island located eighteen miles off the coast of Venezuela. The Island is extremely arid, with no natural fresh water source available. The Island is dependent on seawater desalination to meet its entire potable water requirements. An Island population of approximately 80,000 and a thriving tourist industry of over 100,000 visitors annually, demand a reliable supply of potable ...

  • The devil in the detail of the Water Framework Directive

    Introduction By the end of this year the UK, along with other Member States of the EC, will have transposed the Water Framework Directive (WFD) into national legislation. This is the first step in implementing the most substantial piece of water legislation to come out of Brussels, but the details about what will be required from industry in terms of costs and benefits are still very uncertain. ...

  • Allocation of water consumption in multipurpose reservoirs

    The Intergovernmental Panel on Climate Change Special Report on Renewable Energy Sources represented a benchmark in the assessment of water consumption from electricity production. The numbers for hydropower ranged from very low to much larger than the other renewable technologies, partly explained by methodological problems. One of the methodological shortcomings identified was the lack of ...

  • Eclox Rural Water Association Helps Assure Water Security Statewide with Rapid Response Water Test Kit

    The ability to rapidly monitor the quality of U.S. source water for contamination has never been more important than it is in today’s security-sensitive environment. The Delaware Rural Water Association (DRWA), located in Milford, Del., is a non-profit trade organization, one of 47 state affiliate members of the National Rural Water Association. The mission of the DRWA is to improve the quality ...

  • New field test for Iron in Water

    Iron is a ubiquitous element that is often found in well water, to which itcan give an unpleasant taste. It is important to understand the basic chemistry of iron, how it gets in water, and above all how to test for it accurately and easily. ...

  • Evaluation of new generation brackish water RO

    Since the development of brackish water reverse osmosis (RO) membranes their use has seen rapid development.  All major RO membrane manufacturers have developed one or more brackish water RO membranes.  In the last ten years these membranes have seen a large decrease in price and an increase in productivity making brackish groundwater desalination an attractive option in water scarce regions.  ...

  • Developing a Culture of “Revulsion”: Singapore Tackles Water Wastage

    Singapore is an interesting place. As a city-state it occupies a very small amount of land area, about 700 square kilometers. Packed into this space are 5.6 million people working in one of the world’s strongest economies. A big part of the economy is based on manufacturing and oil refining. Both of these sectors are intensive water users. Because of this, water availability is a big issue. ...

  • Policy Brief on Carbon sensitive urban water futures

    Supplying quality water to a growing population in a world that is changing at breakneck speed is one of the biggest challenges facing society in the 21st century. Attempting at the same time to reduce the amount of embedded carbon and energy used in the delivery systems provides an added test. The "Policy Brief on Carbon sensitive urban water futures" illustrate that the ...

  • Anglian water Cryptosoridium outbreak - Case Study

    Pitsford Drinking Water Site, England In June 2008, a rabbit was located in the wash water tank at the Pitsford Drinking Water Plant of Anglian Water, leading to contamination of the treatment works with Cryptosporidum, a chlorine resistant parasitic micro-organism. The parasite was detected on June 24 and, following consultation with health and local authorities, a notice to boil ...

  • Factors Affecting Oil in Water Testing Methods

    Various factors need to be considered when comparing methods to measure oil and grease in water.  Whether you are trying to meet effluent limits for an NPDES (National Pollutant Discharge Elimination System) permit, comply with oil and grease limits for the Clean Water Act (CWA), or an industry satisfying a POTW’s (Publically Owned Treatment Works) discharge permit, it is ...

  • 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 ...

  • 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 ...

  • System dynamics analysis of water supply and demand in the North China Plain

    Water resource carrying capacity (WRCC) is an important metric for regional sustainable development in China. It is defined as the difference between the total water supply and demand. The North China Plain (NCP) currently faces a serious water shortage if the WRCC is not managed at a sustainable level. This study focuses on applying system dynamics (SD) methodology to evaluate different water ...

  • A conceptual decomposition of MINLP models for the design of water-using systems

    The work presents a systematic methodology for the design of industrial water systems that combines principles of water-pinch (Wang and Smith, 1994a, 1994b) with mathematical programming techniques that enable the imposition of practical constraints and the generalisation of the conceptual tools into multi-contaminant problems. A superstructure model is formulated as an MINLP and solved via ...

  • Genetic algorithm-based optimization of water resources allocation under drought conditions

    The efficient allocation of increasingly scarce water resources is a growing challenge worldwide, particularly during times of drought. This paper describes the development and application of an innovative technique to optimize the allocation of raw water supply to the city of London, UK during a period of drought in 2006. Using genetic algorithms, an optimization tool was developed to derive ...

  • Comparative use of artificial neural networks for the quality assessment of the water reservoirs of Athens

    Neural networks are powerful tools that could explore the basic structure of environmental data. In this work, the most common artificial neural network (ANN) architectures, multi-layer perceptrons (MLPs), radial basis function (RBF) and Kohonen's self-organizing maps (SOM), are applied in order to assess the quality of the water reservoirs used for the domestic and industrial water ...
