  • Rainwater harvesting

    Rainwater harvesting is the gathering, or accumulating and storing, of rainwater.[]1 Rainwater harvesting has been used to provide drinking water, water for livestock, water for irrigation or to refill aquifers in a process called groundwater recharge. Rainwater collected from the roofs of houses, tents and local institutions, or from specially prepared areas of ground, can make an ...

  • Rainwater Harvesting

    With rainwater harvesting, precipitation discharge from roofs of public and private buildings can be collected in cisterns and withdrawn by pumps. The collected water replaces drinking water in areas where drinking water quality is not necessary to be obtained, such as in the household for flush, running the washing machine, to irrigate the garden but also in industrial areas. The main purpose of ...

  • Understanding residential rainwater harvesting

    We use the phrases rainwater harvesting, rainwater utilization, and rainwater collection to describe the process of collecting and using rainwater as an alternative or supplemental water source.  Rainwater harvesting is typically restricted to non-potable (Not for Drinking) applications like: landscape irrigation, vehicle washing, toilet flushing, laundry, cleaning and custodial services, ...

  • 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 ...

  • Ground-breaking innovation in rainwater harvesting

    Rainwater harvesting has for centuries been performed using simple methods. At the start of the 1990s, the first companies began launching standardised components on the German market. In 1997, at the leading international trade fair for sanitary, heating and climate control technology, the ISH, INTEWA was one of the first companies to present a complete station for rainwater harvesting. The ...

  • Rainwater harvesting: environmentally beneficial for the UK?

    Rainwater harvesting (RWH) feels right from a long-term sustainability perspective. Short-cutting the hydrological cycle seems to make logical sense from an environmental stance, and the technique is being driven into new buildings in the United Kingdom (UK) through building rating systems which are in turn pushed by government policy. However, little work has been done to assess its ...

  • 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 ...

  • Assessment of rainwater harvesting systems at a university in Taipei

    Rainwater harvesting systems (RWHSs), a pilot-scale one (PSR) and a full-scale one (FSR), at a university campus in Taipei were assessed. Characteristics of harvested rainwater were analyzed, including pH, electrical conductivity (EC), turbidity, alkalinity, dissolved organic carbon (DOC), total coliform (TC), concentration of 14 metals (Al, Ca, K, Mg, Na, Cu, Fe, Mn, V, Zn, Cd, Cr, Pb and Ni) ...

  • Seoul’s Star City: A rainwater harvesting benchmark for Korea

    A successful rainwater harvesting (RWH) project in the Korean capital, Seoul, has prompted a revision of water policy for the city as a whole and looks set to provide the impetus for increased interest in RWH in other Korean municipalities. Built on a 6.25 hectare site originally owned by Konkuk University, the project answers the classic problem confronting municipal authorities in highly ...

  • Importance of maintenance in rainwater harvesting systems: a case study

    In this study, the quality of collected rainwater at a downtown middle school rainwater harvesting system was evaluated by measuring physical, chemical, and microbiological parameters such as pH, dissolved oxygen (DO), chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP), NO3, PO4, total coliform (TC), Escherichia coli , and some metals (i.e. Al, Cr, ...

  • Harvested rainwater quality: the importance of appropriate design

    This paper summarises the physicochemical and microbiological quality of water from a rainwater harvesting (RWH) system in a UK-based office building. 7 microbiological and 34 physicochemical parameters were analysed during an 8 month period. Physicochemically, harvested rainwater quality posed little health risk; most parameters showed concentrations below widely used guideline levels for ...

  • Rainwater harvesting practices and attitudes in the Mekong Delta of Vietnam

    Access to safe drinking water is limited in the Mekong Delta region of Vietnam. Rainwater harvesting (RWH) at household level is among the primary sources of drinking water in the region and is widely practiced throughout Southeast Asia. It has recently been increasingly advocated as an alternative or supplemental approach to household water supply. However, relatively little research has been ...

  • South Korea leads the way of rainwater harvesting

    Interest in the benefits of rainwater harvesting is becoming widespread in South Korea, which now has 47 “rain cities”. The potential for developing regions to leap ahead in water affairs, by-passing the exposed shortcomings of centralized western systems is never more obvious than in the matter of rainwater harvesting (RWH). Loosely named “rain cities” by ...

  • Rainwater harvesting potentials for drought mitigation in Iran

    In order to evaluate the potential of rainwater harvesting (RWH) for mitigating water scarcity in a semi-arid zone of the country (Mashhad-Iran), three typical RWH systems were installed and monitored. The first system consists of 5,000 m2 natural ground catchment which was leveled and covered with plastic sheets allowing for maximum possible runoff generation. Surface runoff was conducted into a ...
