Abstract

Water-related problems including urban flood and drought have led to developing technologies for rainwater utilization to provide a sustainable water supply for non-potable use in urban area and to buffer extreme runoff situations in the watercourses. However, little information is available on technologies to improve water qualities and runoff properties of collected rainwater for efficient operation of rainwater utilization systems. In this study, a technology to collect high quality of rainwater using sunlight was developed based on the information on the runoff characteristics of rainwater. Samples of runoff rainwater from various catchment surfaces were analyzed for physicochemical and microbial determinants including metals, nutrients, pH, turbidity, conductivity, and microorganisms. The results show that the contamination by turbidity, conductivity, and color occurs during the catchment process. Surface treatment of roof catchment area using TiO2 photocatalyst allowed a better runoff property of rainwater because of its improved hydrophilicity and photo-assisted reactivity.
