  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Severe Drought and Collapsible Water Storage Tanks and Pillow Bladders

    The U.S. Department of Agriculture's Drought Monitor has recently published information indicating that up to 95 percent of Texas is experiencing either "severe" or "exceptional" drought conditions this year. According to the National Weather Service, Texas experienced the hottest period (June through August 2011) on record in the U.S. In addition, the Lower Colorado River Authority (LCRA) ...

  • Our Conical Cone Tanks Are Now WRAS Approved For Drinking Water Storage

    When it comes to quality, Enduramaxx is there. And our cone tanks (conical tanks) are no exception. We are proud to announce that they have just been granted WRAS certification. The Water Regulation Authority Scheme approval means that these tanks are approved for the storage of emergency water for human consumption. This means our cone bottom tanks can be used for applications for storage of ...

  • 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 ...

  • 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 ...

  • An integrated approach to water management in Kayseri: rainwater collection and use in an amusement park

    Water management in urban areas of developing countries is a major environmental challenge for the future. Within the framework of the IWA Cities of the Future Programme, current water and wastewater management systems are investigated in Kayseri, Turkey, with the purpose of bringing water into the center of city life by a reformed pilot project. In order to assess both the quantity and dynamics ...

  • 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 ...

  • Impact of rainwater harvesting systems on nutrient and sediment concentrations in roof runoff

    Rainwater harvesting (RWH) systems have the unique ability to contribute to stormwater management goals via mitigation of runoff volumes and peak flow rates. Additionally, collecting and storing runoff via RWH systems can potentially provide water quality benefits due to physical and chemical processes that occur within the storage tank. This study quantified the water quality improvement ...

  • Quality assessment of roof-harvested rainwater in the West Bank, Palestinian Authority

    Rain harvesting is becoming more common in the Palestinian Territories as a result of drinking water scarcity. Although it might pose serious human health risk, this water is being consumed without treatment in many areas of the West Bank. The present study evaluates the physicochemical and microbial quality of harvested rainwater that is used as potable water in the West Bank. Samples from ...

  • Comparison of biofilm formation and water quality when water from different sources was stored in large commercial water storage tanks

    Rain-, ground- and municipal potable water were stored in low density polyethylene storage tanks for a period of 90 days to determine the effects of long-term storage on the deterioration in the microbial quality of the water. Total viable bacteria present in the stored water and the resultant biofilms were enumerated using heterotrophic plate counts. Polymerase chain reaction (PCR) and ...
