  • Reducing stormwater damage

    When an area is changing from rural to urban, city planners try to measure the impact of development on a whole host of 'quality of life' factors. What will happen to traffic patterns? Will the community need new schools? Who will provide water and sewer services, with how much capacity? These are tough questions, but they are measureable. On the other hand, the pressure of urbanization on ...

  • Turning stormwater into drinking water

    CSIRO scientists have bottled ‘Recharge’ , pure drinking water that was once stormwater. “This is an exciting demonstration of the value of stormwater and the drinking water that can be produced from it by using a combination of natural treatment processes and engineered methods,” CSIRO’s Water for a Healthy Country Flagship Urban Water Stream Leader Dr Peter Dillon said. The water was captured ...

  • Cleaning up the effects of stormwater with biofilters

    Stormwater in urban areas can have negative effects on both the quantity and quality of surface- and ground-waters. Biofiltration systems are a popular form of water treatment, but information on their performance with stormwater is limited to laboratory studies. This research is the first to evaluate three biofiltration systems in practice. Biofiltration systems (otherwise known as biofilters, ...

  • Urban trees enhance water infiltration

    Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. Traditional stormwater management focuses on regulating the flow of runoff to waterways, but generally does little to restore the hydrologic cycle disrupted by extensive pavement and compacted urban soils with low permeability. The lack of infiltration opportunities affects ...
