  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Removing Chloramines from Drinking Water Supplies

    Historically, most public water supplies have been treated with chlorine to satisfy the standards set by the Safe Drinking Water Act of 1974. Since being established, there is reason to believe that the standards may be too lenient on the allowable contaminant levels in our drinking water. For instance, chlorine and other disinfectants react with organic matter creating ...
