·exploitation of many of our rivers and streams; and to initiate a policy of the phasing out of commercial extraction of rock gravel and sand from rivers in favour of the establishment of a regional network of hard rock quarries BACKGROUND Fijis rivers and creeks are a little recognised resource of great subsistence and sustenance
·While upstream sediment management controls will help the natural erosion process in rivers and estuaries will continue Thus navigation dredging will continue to be needed over the very long term Environmental cleanup dredging will be needed for decades to come even as improved controls are placed upon waste and wastewater sources
·In drinking water treatment filtration plays an important role in the multi barrier approach employed for the removal of pathogens The presence of suspended solids and other particulate matter in water increases the resistance of most microbes to disinfection Therefore high performance in the removal of particles achieved by granular filtration can increase the
