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harvesting, precipitation discharge from roofs of public and private buildings can be collected in cisterns and withdrawn by pumps.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

  • 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 ...

  • 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) ...

  • 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 ...

  • Primary School benefits from rainwater harvesting system

    Park Primary School are taking delivery of an Aquaco Rainwater Harvesting System The primary school will shortly be benefitting from a rainwater harvesting system to recycle the rainwater collected from the roof areas for the flushing of toilets within the ...

  • Primary School in Essex gets a rainwater harvesting system

    Rainwater Harvesting System for primary school The Westborough Primary School, near Southend-on-Sea, has ordered a complete rainwater harvesting system from market leader Aquaco. The system comprises of a 10,000 litre single piece underground rainwater collection tank and the Aquaco inline wire mesh leaf filter. A dual submersible pump set provides 100% standby ...

  • Evaluation of the optimal size of a rainwater harvesting system in Sicily

    In the Mediterranean area, water scarcity represents a critical issue due to the increasing water demand related to the population growth and the expansion of urban and industrialized areas. Rainwater harvesting (RWH) may be an effective alternative water supply solution to deal with water scarcity in order to reduce non-potable water needs. The reliability of RWH systems is greatly affected ...

  • 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, ...

  • Rainwater harvesting for Harrow Boys School

    Harrow Boys School have included a 20,000 litre rainwater harvesting system within a new build boarding house. The rainwater harvesting system will collect, filter, disinfect and distribute the harvested rainwater for re-use in W.C. ...

  • Rainwater harvesting for welfare centre in Newcastle

    Shilbottle Welfare Centre Rain Water Harvesting System A complete rainwater harvesting system has been delivered by Aquaco for the Shilbottle Welfare Centre run by Newcastle City Council. The system comprises of a 15,000 litre underground GRP rain water collection tank incorporating a stainless steel mesh leaf filter and dual submersible pump sets which is a typical example of an ...

  • Modelling rainwater harvesting for commercial buildings

    Commercial areas are generally fully paved and with more impervious land cover than residential areas. This paper demonstrates a wall-mounted rainwater harvesting system designed to deal with limited land space. An arrangement of three tanks in series was used on a commercial shop lot where flat roofs generate large amounts of runoff. The system is compact, and can be installed and fitted ...

  • 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 ...

  • Designing a rainwater harvesting system for urban green roof irrigation

    Green roof systems have been suggested to ease the growing urban environmental problems resulting from rapid urbanization. However, the irrigation of green roofs heavily depends on using precious potable water and consequently generates negative environmental effects. Rainwater has been recommended to address this dilemma, but the design method has not been well developed. In this study, the ...

  • Water quality management for domestic rainwater harvesting systems in Fiji

    Health risks from drinking rainwater are relatively small in the developing world context, but action is needed to ensure water safety. Water safety plans (WSPs) use an approach to manage water quality that has shown signs of success with public and communal water supplies, but relatively little research has been done to investigate the application of WSPs to self-supply systems. The aim of this ...

  • Economic feasibility of rainwater harvesting systems: a systematic literature review

    Rainwater harvesting (RWH) systems are increasingly being used as an alternative source of water supply. However, their installation is not often financially feasible. The feasibility analysis of such investments is carried out by traditional techniques that have uncertainty limitations. Thus, the objective of this study is to describe how the studies concerning the economic feasibility of RWH ...

  • Cost-effective rainwater harvesting system in the Metropolitan Area of Barcelona

    Expected population growth will result in increasing water demand. The consequences could potentially jeopardise water resource availability especially in urban areas and significantly increase costs. Rainwater harvesting (RWH) systems can aid not only in meeting water demand partially, but also doing so in a more cost-effective and environmentally friendly manner than other techniques. Although ...

  • Effects of rainwater harvesting on centralized urban water supply systems

    The potential effect of widespread rainwater harvesting practices on mains water demand and quality management are investigated for three different types of urban areas characterized by different roof area to water demand ratios. Two rainfall patterns are considered with similar average annual depths but very different temporal distributions. Supply reliability and the extent of reliance on the ...
