Managed aquifer recharge: rediscovering nature as a leading edge technology

摘要: Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe recent years as an efficient means recycling stormwater or treated sewage effluent for non-potable indirect potable reuse urban rural areas. Yet aquifers have been relied on knowingly water storage unwittingly treatment millennia. Hence if ‘leading edge’ is defined ‘the foremost part a trend; vanguard’, it would be misleading to claim managed aquifer recharge leading edge technology. However taken significant investment scientific research demonstrate the effectiveness sustainable systems enable recognised along side engineered recycling. It ‘cross-over’ technology that applicable wastewater makes use passive low energy processes spectacularly reduce requirements supply. robust within limits, cost, suitable from village city scale supplies, offers yet almost untapped opportunities producing safe drinking supplies where they do not exist. will increasingly valued role securing sustain cities affected by climate change population growth. universal panacea relies presence sources together with effective governance ensure human health environment protection resources planning management.
