  • Get more out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • Drinking Water Analysis Guide

    Public Water Systems (PWS), regulated by the United States Environmental Protection Agency (USEPA), provide drinking water to 90% of Americans. Water systems and laboratories testing drinking water for Safe Drinking Water Act (SDWA) compliance must be certified and must use USEPA approved methods, which are developed by the USEPA, other government agencies, universities, consensus method ...

  • Exergy analysis of an ammonia?water absorption system

    Exergy analysis of an ammonia?water absorption system for cooling applications is presented in this paper. Exergy destruction rate and heat rate in each component of the system are evaluated. From the results obtained it can be concluded that the evaporator and condenser heat loads and exergy destruction rate are less than those of the absorber and generator. This is due to the heat of mixing in ...

  • Analysis of PCB in water using the envirogard test system

    MATRIX: Water ANALYTE: PCB LIMIT OF DETECTION: Aroclor 1248: 1 ppm Aroclor 1260: 2 ppm Aroclor 1242: 2 ppm Aroclor 1254: 1.1 ppm BACKGROUND: This application describes a field screening method for determining PCB concentrations in water. A chemical reaction is induced that causes a color change ...


  • An enquiry into the place of systems analysis in the politics of water and the environment

    In many jurisdictions, the participation of stakeholders in decisions concerning their environment, and their water environment in particular, is still carried out, if at all, on an ad hoc basis. This paper envisions a legislative structure that allows a natural participation by the people in decision-making. While systems analysis and models may inform opinion in the ideal Legislature, ...

  • Analysis of PCB in water using the Dtech test system

    MATRIX: Water ANALYTE: PCB LIMIT OF DETECTION: Color Card: 100 ppb (as aroclor 1254), DTECHTOR meter: 50 ppb (as aroclor 1254) BACKGROUND: This application describes a field screening method for determining PCB concentrations in water. A 1:2 dilution of the sample in methanol is made to minimize adsorptive losses. A ...


  • Guidelines for transient analysis in water transmission and distribution systems

    All water systems leak, and many supply systems do so considerably, with water losses typically of approximately 20% of the water production. The IWA Water Loss Task Force aims for a significant reduction of annual water losses by drafting documents to assist practitioners and others to prevent, monitor and mitigate water losses in water transmission and distribution systems. One of the causes of ...

  • An Analysis of Water Governance in Kibera, Kenya

    Abstract Populations in urban slums continue to rise due to the relatively affordable shelter provision. Most slums are neither planned nor formal and therefore lack basic service delivery. Despite the fact that the majority of inhabitants in these slums are low-wage earners, they are forced to pay more for basic needs such as water than their neighbours in ‘affluent’ and ‘well-to-do’ ...


  • Life Cycle Analysis of Water Networks

    Abstract Water authorities around the world are faced with the problem of ageing distribution networks and often only limited historical data on which to base a sound long term, cost efficient replacement policy. The LICAN approach to whole of life costing is introduced and a hypothetical case study is used to demonstrate the importance of such an approach. A selection of pipe networks ...

  • Decision Analysis Applications for the Sustainability of Global Urban Water Resources and Drainage Systems

    ABSTRACTWater is one of the most vital elements needed for life. In many countries water supplies, especially for critical drinking water, are either being depleted or polluted. Too often these problems are magnified due to the lack of reliable drainage systems that provide proper stormwater and sanitary sewage collection and treatment of human generated wastewater. ...

  • Comparative analysis of the outflow water quality of two sustainable linear drainage systems

    Three different drainage systems were built in a roadside car park located on the outskirts of Oviedo (Spain): two sustainable urban drainage systems (SUDS), a swale and a filter drain; and one conventional drainage system, a concrete ditch, which is representative of the most frequently used roadside drainage system in Spain. The concentrations of pollutants were analyzed in the outflow of all ...

  • 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 ...
