Recently, rainwater management is considered as an essential means for recovering natural hydrological cycles in urban area. However, a lack of technical knowledge on the design of rainwater management system has been identified as a major hurdle preventing widespread application of rainwater management. This study focused on the application of design methods for rainwater management system. A ...

Since groundwater is diminishing rapidly in rural Beijing, rainwater harvesting for irrigation is being promoted. As the cost of pumping up groundwater is low, farmers have few incentives to use rainwater. To promote the consumption of rainwater, the Beijing Water Authority may in the future raise the cost of using groundwater by introducing a charge. Higher cost of groundwater will increase th...

The harvesting of rainwater is gaining acceptance among many governmental authorities in countries such as Australia, Germany, and South Africa, among others. However, conflicting reports on the microbial quality of harvested rainwater have been published. To monitor the presence of potential pathogenic bacteria during high-rainfall periods, rainwater from 29 rainwater tanks was sampled on four...

Introduction Rainwater harvesting is becoming increasingly popular as the availability of good quality water decreases. Rainwater harvesting is acknowledged as a sustainable source of water that has less impact on the environment. In 2004, 17% of households in Australia had rainwater as a source of water. In rural Western Australia 62% of the households owned rainwater tanks and 53% had rainwat...

Abstract: The objective of this study is to assess the potential for potable water savings by using rainwater as well as the sizing of rainwater tanks in houses in some cities in the world. Daily rainfall data for thirteen cities located in different countries were used. Different catchment areas, number of residents, potable and rainwater demands were considered in order to assess their impact...

The global freshwater and energy crisis have prompted worldwide investments in rainwater harvesting and solar energy systems. As the implementation of these two systems develops concurrently, they can easily become integrated into one rooftop structure. Photovoltaic systems have the potential to leach heavy metals and other toxins from newly installed, broken or aged modules. Since the type of ...

This investigation was performed to provide heavy metal signatures of urban soils, dusts, rainwater and to evaluate potential sources in Arak, Markazi Province. Thirty-one samples of urban soils, 29 dust and16 rainwater samples were collected in Arak city. Then, Pb, Cu, Zn, As and Ni concentrations were determined by using atomic absorption spectrophotometry. Application of discriminant analysi...

Rainwater harvesting within the urban environment is being increasingly recognised for its important role in reducing pressures on mains water supply and reducing stormwater runoff. The extent to which rainwater tanks can improve our management of the urban water cycle depends on the level of usage of the rain-harvested water. By incorporating the hotwater service into the suite of uses of harv...

Total water cycle management (TWCM) discussion mostly limits the role of residential rainwater harvesting to providing an alternate water supply to a fraction of fit-for-purpose end uses. However, with operational improvements, greater outcomes can be achieved. By increasing the portion of roof area connected and developing adaptive rainwater diversion (ARD), reliable stormwater management outc...

Due to decreases in the availability and quality of traditional water resources, harvested rainwater is increasingly used for potable and non-potable purposes. In this study, we examined the effect of conventional roofing materials (i.e., asphalt fiberglass shingle, Galvalume(®) metal, and concrete tile) and alternative roofing materials (i.e., cool and green) on the quality of harvested rainwa...
