Unconventional　water　reclamation,　recycling,　and　reuse　have　been　identified　as　the　major　approaches　for　addressing　water　scarcity　in　China.　The　aim　of　this　study　was　to　evaluate　the　technical　and　economic　feasibility　of　water　reclamation　plants　(WRP)　based　on　an　anaerobic-anoxic-oxic　membrane　bioreactor　(A(2)O-MBR)　system　for　unconventional　water　resource　(domestic　wastewater　and　rainwater)　treatment　and　reuse　in　green　building　residential　community.　During　a　year　operation　and　evaluation　process,　average　chemical　oxygen　demand　(COD),　biochemical　oxygen　demand　(BOD5),　total　nitrogen　(TN)　and　total　phosphorus　(TP)　removal　efficiencies　averaged　83.7　+/-　3.2%,　91.6　+/-　2.6%,　69.0　+/-　6.5%　and　74.5　+/-　5.5%,　respectively.　The　effluent　quality　of　wastewater　treated　by　the　A(2)O-MBR　system　complied　with　the　water　quality　standards　for　reuse　for　green　building　residential　community　or　for　direct　discharge.　Typical　seasonal　fluctuations　of　temperature,　COD　loading　rate,　BOD5/COD　and　COD/TN　were　the　key　factors　affecting　pollutants　removal　efficiencies,　and　the　membrane　fouling　rate　was　accelerated　at　low　temperatures.　The　total　cost　of　capital　and　operation　was　0.406　$/m(3),　a　cost-benefit　analysis　incorporating　both　capital　and　operating　expenditures　showed　that　more　than　60%　of　the　reclaimed　water　is　reused　in　the　green　building,　and　the　full-scale　WRP　exhibits　a　positive　net　present　value.　These　results　demonstrated　that　A(2)O-MBR　is　an　efficient　and　profitable　technology　for　nontraditional　water　resource　recycling　in　green　building　residential　communities　in　terms　of　technical　and　economic　feasibility.
