This study describes the use of rainwater and greywater (originated from bathroom only) for provision of non-contact indoor and outdoor use in high-rise buildings. A brownfield development site in Box Hill suburb of Melbourne was selected as case study site for this investigation. The performance of alternative servicing options was compared with conventional water supply, stormwater and wastewater servicing. A water balance model UVQ (Urban Volume and Quality) was applied to determine storage capacities and to evaluate the percentage reduction in water supplying, stormwater run-off and wastewater disposal, as well as volumes of rainwater use and greywater reuse. In this study, the impact of variation in collection area (600 m(2) and 900 m(2)) and appliance discharge volumes was examined. A number of demand management options were also investigated. The results of this study indicate greywater reuse is more suited than rainwater use for this development because of the steady, constant supply of greywater compared to the highly fluctuating, storm-event supply of rainwater and the high population density creating comparatively large volumes of greywater.
本研究描述了雨水和中水（仅源自浴室）在高层建筑中用于非接触式室内外用水的情况。墨尔本Box Hill郊区的一个棕地开发场地被选为该调查的案例研究地点。将替代供水方案的性能与传统供水、雨水和废水处理进行了比较。应用水平衡模型UVQ（城市水量与水质）来确定存储容量，并评估供水、雨水径流和废水处理的减少百分比，以及雨水利用量和中水回用量。在本研究中，考察了集水面积变化（600平方米和900平方米）和器具排水量的影响。还研究了一些需求管理方案。本研究结果表明，由于中水供应稳定、持续，与雨水供应高度波动、受风暴事件影响以及人口密度高导致产生相对大量的中水相比，中水回用比雨水利用更适合该开发项目。
