In 1998, the Ministry of Construction began to investigate rainwater utilization facilities throughout Japan, as part of a wider program of preserving the urban hydrological cycle. As a result, there has been increased recognition that it is important to utilize rainwater for the purpose of effective urban water control and water conservation. Under these circumstances, there will be more construction of rainwater utilization facilities. This paper describes the inspection of rainwater utilization at dome stadiums, which Takenaka Corporation have designed and constructed during the past 10 years in Japan. The dome stadium is a large-scale structure, where baseball games, concerts and various exhibitions are held. A large volume of water supply is needed at one time. Therefore, it is wise to utilize rainwater for the purpose of saving water supplies from a view of water resources in urban areas. Moreover, from the viewpoint of preserving the water environment and runoff control in urban areas, it is important to utilize rainwater. This paper states social background of construction, the outline, design methods, effects and views on the future of all dome stadiums. 相似文献

Shanghai, the economic centre of China, is under increasing pressures of potable water shortage, urban flooding and surface water pollution by urbanization. As one of the best countermeasures, rainwater utilization plays a considerably important role in the alleviation of these issues. A four-step method of cost-effectiveness-based multi-criteria optimization (CEMCO), which integrates the advantages of monitoring data, monetary-based techniques and stakeholder preferences, was proposed for sustainable rainwater utilization. The first rainwater utilization system in the urban residential area of Shanghai was taken as a case study, and eight alternatives to the existing system were proposed. The results of the study showed that the net present value and the dynamic payback period of the optimized system during the 15-year life cycle were 407.4 thousand CNY (ChiNa Yuan) and 8.26 years, respectively. The results also indicated that rainwater utilization can improve the sustainability of cities when different stakeholder preferences and multiple criteria were considered. 相似文献

The potential offered by non‐conventional water resources (rainwater) associated with high or low urban density in new housing in different rainfall zones (800–2300 mm) was studied. Ten cities in Colombia with over 250 000 inhabitants were used as a case study. The potential of substitution of tap water by rainwater according to population groups with different socioeconomic status was estimated. This study reveals the favourable conditions for rainwater harvesting in the Colombian context, and enables the linking of supply and demand issues related to local climatic and environmental sustainability in order to integrate the use of rainwater into urban housing projects. For the current consumption scenario (greater than 160 Lcd), rainwater becomes a potential replacement for mains water in urban areas with rainfall of above 1553 L/m2/year. 相似文献
