The possibilities for implementing a rainwater collection system in Ringdansen, a residential area in Norrköping, Sweden, have been explored by analysing four scenarios for using rainwater in a dual water supply system to supplement drinking water. A computer model has been generated to quantify the water saving potential of the rainwater collection scheme. The performance of the rainwater system is described by its water saving efficiency (WSE). Standard and low water consumption appliances have been taken into account in evaluating WSE and water conservation. According to the analysis, suggested rainwater tank sizes are presented. 相似文献

A dimensionless methodology to evaluate the water saving obtainable from large-scale implementation of domestic rain water harvesting (RWH) systems in urban areas is presented. The methodology combines the use of regressive relationships for water saving evaluation based on the results of the dimensionless rainwater tank water balance and of catchment-wide information obtained from geospatial databases. The adopted RWH scheme included internal use of rainwater for toilet flushing and external use for garden irrigation. An application to a portion of the city of Rome, Italy showed the methodology to allow systematic and accurate evaluation of RWH system performance at the selected urban scale. Results pointed out high water saving potential for toilet flushing ranging between 38–65% for tank sizes within 1–50 m3. Furthermore, more than one third of the systems provided water saving benefit for irrigation larger than 20% by using a 50 m3 tank. 相似文献

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

论北京市城区雨水处理问题 总被引:1,自引:0,他引:1
通过对北京市西滨河、南护城河和东护城河河水水质的监测调研,发现造成北京市城区内河湖”富营养化”的主要原因,是雨水径流将雨污合流管道中大量污水、污泥经过截流设施冲刷进入河湖所致。提出了北京市城区雨水的处理应通过在新建小区、广场和大面积绿地下修建雨水调节池或一级处理场;充分利用北京现有十余座已经停止运转或废弃的泵站,在泵站附近建调节池或一级处理场;同时加强旧沟改造等措施来改善因”雨污合流”造成的河湖污染;在城区环路立交桥积水点附近修建雨水收集池,可以解决积水造成的交通堵塞问题、满足立交桥绿化用水,同时可以减轻雨水对城区内河湖污染的四项建议。 相似文献

节水与水资源利用是绿色建筑的重要内容。雨水利用能够起到"开源"的作用,同时减少雨水外排、减轻面源污染是"海绵城市"建设的重要组成部分。某绿色建筑项目收集建筑屋面雨水,利用周边的景观水池做为蓄水空间。收集的雨水经过过滤处理后用于周边绿化灌溉及道路冲洗。本设计将景观与雨水利用相结合,契合了"海绵城市"建设提倡的蓄水及雨水利用方针。 相似文献
