[摘要] Dillon P., Page, D., Dandy, G., Leonard, R., Tjandraatmadja, G., Vanderzalm, J., Rouse, K., Barry, K., Gonzalez, D. and Myers, B., 2014, Managed Aquifer Recharge Stormwater Use Options: Summary of Research Findings, Goyder Institute for Water Research, Technical Report14/X.The Managed Aquifer Recharge and Stormwater Use Options (MARSUO) research project was a 3.5 year project (that ran from Nov 2010 to May 2014), that and evaluated in depth the quality of stormwater generated in the city of Salisbury, the treatment requirements and risk management measures necessary to assure safe water quality for public open space irrigation, third pipe reticulation to homes and for potential drinking water supplies.It also evaluated and compared the economics of these options for a case study at Parafield in Salisbury, South Australia, accounting for basic assessments of environmental and social impacts.Focus groups and two web surveys were conducted to evaluate public acceptance of the different uses of stormwater.An evaluation of biofilm in pipes of different materials was undertaken for mains water and stormwater to assess the likelihood of water quality changes and potential impacts on infrastructure maintenance.Studies of satellite sites in Australia and overseas were undertaken to compare stormwater quality and treatment requirements for potable use and allow interpretation of the relevance of results from Salisbury. These studies were required initiated under the South Australian Government’s 2009 Water Resources Plan “Water For Good” (Action 94) to ascertain the safety, economics and public acceptance of stormwater for use in drinking water supplies.The studies were also an integral part of the National Water Reform Initiative to demonstrate assess the suitability of all forms of water for water supply,and to determine the economic benefits and public acceptance of diversification of urban water supplies. This aimed to , and thereby determine the possibilities for more efficient water supplies and reduced environmental impacts of stormwater as Australian cities grow and urban areas consolidate.Methods applied were compliant with Australian Guidelines for Water Recycling in the National Water Quality Management Strategy.Water quality was monitored at a number of sites to inform a risk assessment which led to the development of a risk management plan.
