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 ...

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 ...

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 ...

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 ...

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 would have to be extended to include the surface water of Oued Sebu, if water requirements ...

Securing safe drinking water supply under climate change conditions
Water suppliers worldwide are challenged by climate variations, but so far only the qualitative change in boundary conditions has become clear but not yet the degree and impact on the water supply systems. Short-term quality changes in surface waters can, e.g. be caused by extreme rainfalls after dry periods. Longer heat periods without rain can induce middle-term quality changes in surface ...

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 carcinogenic by-products1. ...
