  • Water management solutions minimize flood damage

    Human societies around the world have used timber as a building material for thousands of years. As wood is the only significant biological building material we are naturally inclined to believe that using wood in construction is good for the environment. As a matter of fact the environmental benefits of using timber are not straightforward: although it is a natural product, a large amount of ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • A dynamic urban development model designed for purposes in the field of urban water management

    Urban drainage systems are a critical part of city infrastructure. Population growth and urban development can put severe pressure on these systems, especially due to sealing of surfaces and land use change. For a comprehensive adaptation of urban water infrastructure to constantly changing and evolving systems, a detailed simulation of the dynamics in city development is crucial. This can be ...

  • 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 ...

  • Urban water management and planning: urban sanitation policies and an emerging institutional structure

    Brazilian urban politics for the last two decades have been marked by the emergence of organised sectors of civil society who progressively reclaimed their roles as subjects. Both society and state were substantially transformed in such process, and urban and environmental policies, sanitation included, based on citizens' participation are an important and visible outcome. Participatory ...

  • Characterization of bacterial pathogens in rural and urban irrigation water

    The study aimed to compare the bacteriological quality of an urban and rural irrigation water source. Bacterial counts, characterization, identification and diversity of aerobic bacteria were determined. Escherichia coli isolated from both sites was subjected to antibiotic susceptibility testing, virulence gene (Stx1/Stx2 and eae) ...

  • Applying incentives to increase revenue water in urban systems

    The study utilises cross-sectional data from utilities of the National Water and Sewerage Corporation of Uganda to test application of extrinsic incentive theory on non-revenue water (NRW) reduction. Applying a multiple regression model, we find that the effect of level of incentive payments on revenue water (billing efficiency) depends on the amounts of staff inputs, service coverage and water ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...
