  • Return of drinking water supply in Paris to public control

    The ‘reclaiming’ by Paris of its water back into public hands is a paradox in the homeland of transnational water companies and at a time when the European Commission rather favours the liberalisation of public services ‘of general economic interest’. Yet what has happened is more complex. A quick historical review of management formulas in Europe reveals both the ...

  • Mimicking the private sector: new public management in the water supply and sanitation sector

    In addition to the increase of private sector participation over the past decades, the private sector has impacted the water supply and sanitation sector in another way, by serving as an example for reforming public utilities. Most notably, the management practices of utilities appear to have been copied from the private sector, as well as the institutional arrangements under which the utilities ...

  • Prediction of the quality of public water supply using artificial neural networks

    The Health Surveillance Program was established by the Regional Health Authority of Alentejo to control the quality of public water supply. This authority divides the water quality parameters into three distinct groups, namely P1 (pH and conductivity), P2 (nitrate and manganese) and P3 (sodium and potassium), for which the sampling frequency is dissimilar. Thus, the ...

  • Pharmaceuticals and water supply

    Prescription Drugs have been detected in water supply systems of major cities in the United States including Europe, Canada, Australia and Asia.  In addition, quantities of antibiotics, steroids, antidepressants, and hormones are also present in the water supply (Doro-on, 2011).  These new emerging contaminants are designed with small concentrations that can generate specific health ...

  • Water aggressiveness and hydrodynamic effects on the fibres release in asbestos-cement pipes for public water supply

    SEM and TEM analyses of drinking water samples, collected during three years (1988, 1989 and 1990) from some Asbestos-Cement (A/C) distribution systems in Veneto Region (Italy), have shown that the release of fibres, with length greater than 10 μm, is, on average, quite low. Moreover, the asbestos concentration is not strictly dependent on Aggressiveness Index (A.I.) in the range ...

  • Direct Potable Reuse: Benefits for Public Water Supplies, Agriculture, the Environment and Energy Conservation

    INTRODUCTION Direct potable reuse (DPR), in which purified municipal wastewater is introduced into a water treatment plant intake or directly into the water distribution system, is becoming an increasingly attractive alternative to developing new water sources (Tchobanoglous et al., 2011). The rationale for DPR is based on the technical ability to reliably produce purified water that ...

  • Nitrate and Nitrite Levels of Potable Water Supply in Warri, Nigeria: A Public Health Concern

    In this study, the authors investigated the nitrate and nitrite in different water sources (surface water, shallow well water, and borehole water) in the market and industrialized areas of Warri in the Niger Delta area of Nigeria. The authors’ goal was to find the comparative levels of nitrates and nitrites from these two parts of the community. They selected five sampling sites from ...

  • Application of solar disinfection for treatment of contaminated public water supply in a developing country: field observations

    A sustainable and low-cost point-of-use household drinking water solar disinfection (SODIS) technology was successfully applied to treat microbiologically contaminated water. Field experiments were conducted to determine the efficiency of SODIS and evaluate the potential benefits and limitations of SODIS under local climatic conditions in Karachi, Pakistan. In order to enhance the efficiency of ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • Challenges of public water provision in Nigerian cities: a review

    In spite of the importance of adequate water quality and quantity for human health and survival, public water supply coverage in Nigerian cities appears to be decreasing and deteriorating. Hence, this study was designed to assess the challenges of public water provision in Nigerian cities. Some of the reasons for this deterioration include: inadequate water supply policy, lack of autonomy for ...

  • Structuring and Governing the Use of Public Private Partnerships in Water

    Water is essential for life. Historically, governments or governing regimes have been responsible for delivering good quality water supply to their residents. However, recently, in many parts of the world there has been shift away from public delivery towards the use of public private partnerships ...

  • Public Involvement in Pollution Management

    Formal public involvement at the scoping and draft review stages is part of the Environmental Assessment process and is usually required for industrial projects. However, the wider use of participatory approaches in World Bank pollution management projects is still evolving. Public involvement in setting priorities for pollution management is no yet common although there is evidence that an ...

  • Impact of AMD processes on the public water supply: hydrochemical variations and application of a classification model to a river in the Iberian Pyritic Belt S.W. Spain

    The aim of this work is to formulate a rapid method for finding out the degree of water pollution in the field, based on the toxicity produced by sulfates and metals dissolved in solution, using simple pH measurement in rivers that undergo AMD processes and which flow into public water supply dams. A classification model based on the degree of the impact is proposed, which is applied to a river ...

  • Hydrogeological and economical simulations: emergency water supply for Muscat

    Urban water in Gulf Cooperation Council countries is principally supplied from desalination plants. However, desalination could be interrupted by natural hazards such as cyclones or harmful algal blooms. Four scenarios have been considered to help public institutions in Muscat to establish a water strategy for emergency situations. The numerical simulations of groundwater pumping have shown that ...

  • Groundwater use and policy in community water supply in Finland

    Selection between ground and surface water in community water supply has been one of the key strategic questions in Finland since the early 1900s. After some cities failed to find reliable groundwater sources, many turned to surface waters. Since the 1950s the use of groundwater and artificial recharged groundwater have continuously increased. Presently their use is promoted by the government and ...

  • Private sector involvement in drinking water supply in Ghana

    Two approaches by Private Sector Involvement (PSI) in drinking water supply are followed in Ghana. In the urban areas the public utility (Ghana Water Company Limited) now has private sector management via a management contract, whereas in the small towns and rural areas the responsibility for water services is decentralised. The District Assemblies use the Community Water and Sanitation Agency ...

  • Lead in Drinking Water for small supply systems

    The problem of lead in drinking water is most-publicized for the larger water supply systems of Cities and Towns, particularly the older districts, where lead piping was often used to connect houses to a municipal water supply system and for internal plumbing, unto the early 1980s (generally). The problem is more closely associated with the longer established industrialized and urbanized ...
