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harvesting, precipitation discharge from roofs of public and private buildings can be collected in cisterns and withdrawn by pumps.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

  • Effect of first flush on storage-reliability-yield of rainwater harvesting

    Rainwater harvesting (RWH) entails capture of rainwater falling on a roof and conveyance to a storage tank for later use as domestic water supply. During dry weather, dust and pollutants accumulate on the roof surface and are subsequently washed off with the ‘first flush’ at the beginning of the next rain. Diverting the first flush can improve the quality of stored water but at the cost of ...

  • 10 Uses of Rainwater

    Collecting your own rainwater is an excellent way to conserve this precious resource. A basic rainwater collection system catches rainwater from your roof or other surface and channels it into a container for storage. Rainwater itself is generally clean, but it can pick up microorganisms, pollutants and debris when it hits your roof. This is why systems for rainwater use inside your home often ...

  • Assessment of rainwater harvesting for drinking water supply in Bangladesh

    Rainwater harvesting is a potential option of water supply to the coastal and arsenic affected rural communities in Bangladesh and during the last few years, several projects were undertaken to promote and install various types of rainwater harvesting systems by government organizations and NGOs mainly for drinking and cooking water supply. A study was undertaken to assess the currently practiced ...

  • Rainwater suitable as replacement for tap water in individual cases

    A Parliamentary initiative (10.503) launched by National Councillor Adèle Thorens Goumaz (Greens) calls for rainwater to be used more extensively for purposes that do not require drinking water quality. The initiator is hoping to reduce the consumption of drinking water as a result. In addition, the initiative is seeking to increase the amount of rainwater that percolates into the soil. ...

  • Rainwater harvesting: quality assessment and utilization in The Netherlands

    The use of roof-collected rainwater as a freely available and sustainable alternative to drinking water produced by drinking water companies increases worldwide. Initially, rainwater is free of microbial contamination, but it may become contaminated by animals and humans or, alternatively, human pathogens may grow in stored rainwater resulting in a significant human health risk from infectious ...

  • 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) ...

  • 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 ...

  • Quality and suitability of harvested rainwater for drinking in Bangladesh

    Several programs have been undertaken during the last few years to install rooftop rainwater harvesting systems as an alternative drinking water supply source both in the coastal and arsenic affected areas in Bangladesh. In this study, quality of the harvested rainwater used for drinking water supply was assessed. A total of 308 harvested rainwater samples were collected from the different ...

  • Comparing the microbial characteristics of rainwater in two operating rainwater tanks with different surface-to-volume ratios

    In this study, the microbial characteristics of rainwater in two tanks with different surface-to-volume ratios were investigated and compared to determine how the internal design features of storage tanks affect water quality. The particle and nutrient parameters of the rainwater, including turbidity, suspended solids, total organic carbon, and total phosphate, were lower in Tank 2, which had a ...

  • Stochastic modelling of the hydraulic performance of an onsite rainwater harvesting system in Mediterranean climate

    The performance of onsite rainwater harvesting (RWH) system in Mediterranean climate was assessed. A stochastic model quantifying the necessary storage, as a function of rainfall (frequency, depth), roof area, residents’ number, specific water use (toilet flushing, laundry) and the required efficiency was developed. Two performance indicators were calculated: water saving efficiency (RSE) – ...

  • Performance of pervious pavement parking bays storing rainwater in the north of Spain

    Pervious pavements are drainage techniques that improve urban water management in a sustainable manner. An experimental pervious pavement parking area has been constructed in the north of Spain (Santander), with the aim of harvesting good quality rainwater. Forty-five pervious pavement structures have been designed and constructed to measure stored water quantity and quality simultaneously. Ten ...

  • Performance evaluation of rainwater harvesting system and strategy for dry season challenge

    The extensive application of rainwater harvesting (RWH) projects is inhibited by the challenge posed by the dry seasons. In a case study of Mnyundo Primary School, Tanzania, the performance of the RWH system was evaluated using a daily water balance model. The methodology is based on defined dry season parameters – no water days (NWDs), rainwater usage ratio (RUR), and water level in local ...

  • Designing domestic rainwater harvesting systems under different climatic regimes in Italy

    Nowadays domestic rainwater harvesting practices are recognized as effective tools to improve the sustainability of drainage systems within the urban environment, by contributing to limiting the demand for potable water and, at the same time, by mitigating the generation of storm water runoff at the source. The final objective of this paper is to define regression curves to size domestic ...

  • Benefits of rainwater harvesting for gardening and implications for future policy in Namibia

    Rainwater harvesting to irrigate small-scale gardens enhances food self-sufficiency to overcome rural poverty. So far rainwater harvesting is not encouraged by the Namibian National Water Supply and Sanitation Policy nor supported financially by the Namibian government. This study proposes two rainwater harvesting facilities to irrigate gardens; one collects rain from household roofs with tank ...

  • Quality assessment of rooftop runoff and harvested rainwater from a building catchment

    A major obstacle to the promotion of rainwater harvesting is chemical and microbiological concerns. To determine its suitability as an alternative water resource, water quality parameters such as pH, turbidity and metal ion concentrations and counted total coliform, Escherichia coli and heterotrophic bacteria were measured. It was observed that the stored rainwater had a neutral average pH and ...

    Pervious pavements are sustainable urban drainage systems already known as rainwater infiltration techniques which reduce runoff formation and diffuse pollution in cities. The present research is focused on the design and construction of an experimental parking area, composed of 45 pervious pavement parking bays. Every pervious pavement was experimentally designed to store rainwater and measure ...

  • 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 ...
