  • Frequency pressure regulation in water supply systems

    In water supply systems, pressure management in most cases is proven to be the most cost-effective activity related to water loss control. As an advanced method of pressure control, it is possible to use variable frequency drives for centrifugal pump control. Pressure regulation can be performed with constant pressure or with proportional pressure control. The application of proportional ...

  • Decoupling dependence on natural water: reflexivity in the regulation and allocation of water in Israel

    Since 1999, Israel has secured a decoupling between the total water supplied and water derived from the natural environment through surface and groundwater. Between 2007 and 2010, this decoupling enabled a cut of over 20% in natural water use, while maintaining overall supply volumes despite drought. By 2009–2010, natural water supply had been reduced to the levels of the early ...

  • Opinion: Environmental regulation in the 21st century

That unremarkable statement of aim is at the ...
