  • 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 ...

  • The hidden urban tail-enders – drinking water supply as a common pool resource problem in Khorezm, Uzbekistan

    In academic debates, drinking water supply is considered mainly to be either a public or an economic good, or something in between. Nevertheless, in situations of insufficient supply, the non-academic literature refers to common pool resource problems, in which certain uses of drinking water should be 'avoided' or even 'punished'. To highlight the importance of understanding drinking water supply ...

  • 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 ...

  • 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 ...

  • Spatial analysis of rural drinking water supply in China

    A spatial autocorrelation analysis method was employed to process the spatial change of rural water supply over the past 19 years in the People's Republic of China. Statistical analyses indicate great achievements in rural water supply construction. Two main indices describing rural drinking water supply status, the Rural Popularization Rate of Tap Water and the Rural Popularization Rate ...

  • Application of a risk management framework to a drinking water supply augmented by stormwater recharge

    The Blue Lake is an important water resource for the city of Mount Gambier and the surrounding region, primarily as the drinking water supply source, but also as a tourist attraction. Mount Gambier’s stormwater is discharged directly via drainage wells into the unconfined, karstic Gambier Limestone aquifer, which in turn provides the majority of recharge to Blue Lake. Discharge of urban runoff to ...

  • Considering Policy Implementation Alongside Policy Formulation in Drinking Water Management in New Zealand and for Pacific Islands Giving Voice to Local Knowledge

    This paper reflects on the experiences of the authors in facilitating the involvement of small, rural, and isolated communities in the development of national drinking water standards for New Zealand. The key message we want to give in this paper is the value of involving the communities that are expected to implement policies or plans as these are formulated, to avoid the situation of policies ...

  • Experiences with the practical implementation and operation of biological nitrification for a small-scale drinking water treatment plant

    The implementation and evaluation of biological nitrification as a possible treatment option for the small-scale drinking water supply of a rural Upper Austrian community was investigated. The drinking water supply of this community (average system input volume: 20 m3/d) is based on the use of deep anaerobic groundwater with a high ammonium content of geogenic origin (up to 5 mg/l) which must ...

  • Alternative Regenerants

    The MIEX® Technology was originally designed for the removal of dissolved organic carbon (DOC), a precursor tothe formation of THMs and HAAs, from drinking water supplies. More recently, the MIEX® Technology is finding many more applications for the removal of a range of contaminants across many industries. Traditionally, DOC-loaded MIEX® Resin has been regenerated using brine, a concentrated ...

  • 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 ...

  • Success or failure: demonstrating the effectiveness of a Water Safety Plan

    The Water Safety Plan (WSP) concept has become a globally recognised and accepted approach to drinking water supply management and operation. Many countries around the world are adopting this proactive, risk-based model for ensuring consistent confidence in drinking water safety, accessibility and affordability. While it is widely accepted that the WSP concept is an appropriate tool for ensuring ...

  • Clarification of algae-laden water using electrochemical processes

    Algae contamination of surface water and drinking water supplies is a significant problem particularly in rural areas. A decentralized inexpensive technology that would effectively remove algae from water would be beneficial. Electrocoagulation (EC) combined with electroflotation (EF) as a single process (ECF) is a promising algae harvesting technique with no moving parts that may be powered ...

  • Characterising microbial quality of household greywater

    In supplementing and substituting existing drinking water supplies with alternative water sources such as greywater, it is important that potential health impacts are considered and that water is safe for its designated purpose. It is difficult to detect greywater-associated gastrointestinal illness at the level of single households, such as might potentially occur following handling of untreated ...
