Assessment on rainwater use and grey water reuse in high-rise buildings in brown field site
This study describes the implementation of rainwater and greywater (originated from bathroom only) for provision of non-contact indoor and outdoor use in high-rise buildings. The target study area, Box Hill, which is a typical brownfield site, is chosen for this research. The performance of alternative water resources is developed by considering mains water supply, stormwater management and wastewater discharge as a holistic water system. Urban water cycle model UVQ (Urban Volume and Quality) is applied to determine storage capacity and to evaluate the percentage of reduction in scheme water supplying, stormwater run-off and wastewater disposal, as well as volume of rainwater use and greywater reuse. The impact of varying available collection area and appliances discharge volume has been examined in order to estimate the integrated water system in this study. A number of insights into options which adapt various water demand levels have also been explored. The results of this research indicate that greywater reuse is more suited to rain water use for Box Hill because, sufficiency and succession of greywater supply, deficiency and fluctuation of rainfall and high density occupancy.
