  • Rainwater harvesting: An untapped resource

    The collection of rainwater as a source of relatively clean water has been a common practice of humankind since the dawn of civilization. Before the development of any treatment processes, it was the primary source of potable water for those people without access to other sources of water (rivers, lakes, etc.) As cities developed, infrastructure became more centralized. Municipalities took over ...

  • Quality assessment of rainwater and harvested rainwater stored in different types of cisterns

    Rainwater is widely collected and stored in cisterns for domestic use due to extreme water scarcity and poor water quality on the Loess Plateau, China. However, little information exists on the effects of cistern materials and construction methods on water quality. This study assessed the quality of rainwater and harvested rainwater stored in different types of cisterns, using multivariate ...

  • Rainwater Harvesting

    With rainwater harvesting, precipitation discharge from roofs of public and private buildings can be collected in cisterns and withdrawn by pumps.

  • How supply system design can reduce the energy footprint of rainwater supply in urban areas in Australia

    In Australia rainwater tanks are used in cities to reduce demand of mains water and increase the resilience of cities to drought. Rainwater is collected in a tank and supplied to a dwelling through a small pump. Typically the energy footprint for rainwater supply (in kWh/kL) is higher than for centralised water supply, but it can also vary markedly from dwelling to dwelling (0.4–11 ...
