  • Urban-Water Harmony model to evaluate the urban water management

    Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The ...

  • Urban Hydrology

    The provision and disposal of water for urban populations is as old as the development of cities themselves. Unrestrained development has made the task ever more difficult and hydrologists and civil engineers face constant pressures to stay on top of the challenges of providing sufficient supplies and adequate treatment/disposal of effluents. Urban areas have long existed as centres of trade, ...

  • Urban Lakes

    BritishFlora's expertise in delivery of cost-effective Remediation of Urban Lake. For years fish had been dying in the dirty, silted waters of Bracknell Mill Pond. When Bracknell Town Council, in partnership with Thames Water and the Environment Agency, resolved to transform this operational flood storage lagoon into a flagship wildlife and recreation resource, no one was more pleased ...

  • Application of the urban water use model for urban water use management purposes

    The aim of this work is to present an application of the urban water use (UWU) model, which is a support decision tool to define the best group of efficient water use measures for UWU management purposes. Therefore, the UWU was developed under integrated urban water management (IUWM) and strategic planning principles to promote a systemic approach for decision taking. The IUWM considers the ...

  • Water security and sustainability in urban India

    The rapid growth of population combined with rising levels of consumption and pollution has increased water insecurity in urban India. The depleting water sources on the one hand, higher financial and technological costs to refine and transport water from far off sources on the other, leave limited possibilities to augment the water supply in the near future. Climate change may further adversely ...

  • Demand management in urban water supply

    Since the 1930s, the drinking water supply of the Rabat-Casablanca coastal area has depended on water transfers from groundwater, from Maamora, and surface water, from the Bou Regreg Basin. Assessments carried out during the 1980s, based on patterns of water use at that time, showed that by 2010, transfers ...

  • Alternatives for safe water provision in urban and peri-urban slums

    In response to rapid urbanization throughout the global South, urban and peri-urban slums are expanding at an alarming rate. Owing to inadequate financial and institutional resources at the municipal level, conventional approaches for safe water provision with centralized treatment and distribution infrastructure have been unable to keep pace with rapidly growing demand. In the absence of ...

  • Understanding urban residential end uses of water

    The ‘end use’ of water is a breakdown of the total household water usage such as water used for toilets, showers, washing machines, taps, lawn watering, etc. Understanding end uses of water will enable water planners, water authorities and household owners determine where water is used/wasted, how much and how often. This paper describes the end uses of water from a number of single-family homes ...

  • Adapting urban water systems to climate change

    This handbook on adaptation of urban water systems to climate change is an initiative of the SWITCH project1 and the result of a collaboration between ICLEI – Local Governments for Sustainability, the International Water Association (IWA) and the UNESCO-IHE Institute for Water Education. It draws on the research and findings from the SWITCH1 and PREPARED2 EU Framework Programme projects. ...

  • An integrated approach for urban water quality assessment

    This paper introduces an integrated approach for the assessment of receiving water quality and the relative contribution of the urban drainage system to perceived receiving water quality problems. The approach combines mass balances with relatively simple receiving water impact models. The research project has learned that the urban drainage system is only one of the determining factors with ...

  • Report on carbon sensitive urban water futures

    The challenge of supplying water and energy required for food production and development while mitigating climate change and adapting to its consequences has been termed the Energy Water Nexus. Water, energy, greenhouse gas emissions and climate change are interlinked through a series ...

  • Customer perspectives on new urban water services

    The TRUST report "Customer perspectives on new urban water services" presents the results of an initial literature review, encompassing both academic and grey literature, which focused on understanding the "customer perspective" and what they value and might be ...

  • Urban domestic water pricing in India and China

    Despite significant differences in political and administrative structures, recent reforms in urban domestic water tariff regimes in India and China have had similar trajectories with important but sometimes nuanced differences. In both countries, there has been a devolution of operational authority to municipal governments and acceptance of greater reliance on cost recovery through user fees. ...

  • Integrated urban water management in commercial buildings

    Monitoring results are presented as an annual water balance from the pioneering Landcare Research green building containing commercial laboratory and office space. The building makes use of harvested roof runoff to flush toilets and urinals and irrigate glasshouse experiments, reducing the demand for city-supplied water and stormwater runoff. Stormwater treatment devices also manage the runoff ...

  • Urban evaporation rates for water-permeable pavements

    In urban areas the natural water balance is disturbed. Infiltration and evaporation are reduced, resulting in a high surface runoff and a typical city climate, which can lead to floods and damages. Water-permeable pavements have a high infiltration rate that reduces surface runoff by increasing the groundwater recharge. The high water retention capacity of the street body of up to 51 l/m2 and its ...

  • Water quality assessment of a polluted urban river

    Urban rivers in Latin America are heavily impacted by human activities that affect their functions and services. This paper shows the results of a water quality assessment for the Reconquista River, the second most polluted urban river in Argentina. They allowed the identification of the main processes of transport of pollutants and the prioritisation of different areas of the basin for ...

  • Energy Efficiency for Urban Water and Wastewater Services

    Electricity is a critical input for delivering municipal water and wastewater services. Electricity costs are usually between 5% - 30% of total operating costs among water and wastewater utilities (WWUs) worldwide. The share is usually higher in developing countries and can go up to 40% or more in some countries (e.g. India and Bangladesh). Such energy costs translate into high and often ...

  • Adaptable urban water demand prediction system

    In this work, identification of 24-hours-ahead water demand prediction model based on historical water demand data is considered. As part of the identification procedure, the input variable selection algorithm based on partial mutual information is implemented. It is shown that meteorological data on a daily basis are not relevant for the water demand prediction in the sense of partial mutual ...

  • Constructed wetlands for urban grey water recycling

    Three differently configured constructed wetlands: a Horizontal Flow Reed Bed (HFRB), Vertical Flow Reed Bed (VFRB) and a novel constructed wetland (the Green Roof Water Recycling System (GROW) patent number GB 2375761) were compared for treatment of weak organic strength domestic grey water for reuse over a period of nine months. Influent and effluent were characterized in terms of standard ...
