An innovative strategy for stormwater remediation and reduction of contaminant supply from catchments. Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment. In a radical shift from traditional approaches, we will identify primary contaminant sources in the catchment for later targeted education and regulation and a single remediation device will r ....An innovative strategy for stormwater remediation and reduction of contaminant supply from catchments. Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment. In a radical shift from traditional approaches, we will identify primary contaminant sources in the catchment for later targeted education and regulation and a single remediation device will remove most toxic substances in stormwater currently discharged to estuaries. Stormwater reuse will provide a new valuable urban resource. This paradigm shift in traditional stormwater strategy will ensure biodiversity and ecologically sustainable development of urbanised ports. Port Jackson is used as a test case.Read moreRead less
