With the growth of urban areas and climate change, decisions need to be taken to improve water management. This paper reports an assessment of the impact of greywater recycling systems on catchment scale hydrological flows. A simulation model developed in InfoWorks CS (Wallingford Software Ltd) was used to evaluate how river flows, sewer flows, surface runoff and flooding events may be influenced when grey water recycling systems of different number and scale are implemented in a representative catchment. The simulations show the effectiveness of greywater recycling systems in reducing total wastewater volume and flood volume. However, no hydraulic impacts due to implementation of greywater was identified by the model.
随着城市地区的发展和气候变化，需要做出决策来改善水资源管理。本文报告了对中水回用系统对流域尺度水文流量影响的评估。使用InfoWorks CS（沃灵福德软件有限公司）开发的模拟模型来评估在一个具有代表性的流域实施不同数量和规模的中水回用系统时，河流流量、下水道流量、地表径流和洪水事件可能受到的影响。模拟结果表明了中水回用系统在减少总废水量和洪水量方面的有效性。然而，该模型未识别出由于实施中水回用而产生的水力影响。
