  • 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 ...

  • Tesco supermarket gets a 20,000 litre rainwater recycling system

    Tesco's Extension in Sutton Aquaco provided the supermarket store in Sutton with a 20,000 litre rainwater recycling system including dual pump sets, 500 litre header tank, ground filter and an UV unit. This was fitted in to their extension for toilet ...

  • Impacts of using rainwater tanks on stormwater harvesting and runoff quality

    The popularity of rainwater use in Australia depends completely on the individual householder's preference. The quality of reticulated water supplies in major cities of Australia is far superior to water stored in rainwater tanks. However, due to persistent drought and the implementation of stringent water restrictions, cities such as Melbourne have encouraged the use of rainwater harvesting ...

  • Historical development of rainwater harvesting and use in Hellas: a preliminary review

    The uneven temporal and partial distribution of water resources in Hellas, and especially southeastern regions, has resulted in the construction of various water systems for collection and storage of rainwater, since their very early habitation. Ever since, technologies for the construction and use of several types of cisterns and other relevant hydraulic strictures have been developed. The ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Design and construction of an experimental pervious paved parking area to harvest reusable rainwater

    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 ...
