Roof selection for rainwater harvesting: quantity and quality assessments in Spain.
Roofs are the first candidates for rainwater harvesting in urban areas. This research integrates quantitative and qualitative data of rooftop stormwater runoff in an urban Mediterranean-weather environment. The objective of this paper is to provide criteria for the roof selection in order to maximise the availability and quality of rainwater. Four roofs have been selected and monitored over a p...
متن کاملQuality 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 roo...
متن کاملA Review of Roof Harvested Rainwater in Australia
To address concern regarding water sustainability, the Australian Federal Government and many state governments have implemented regulatory mechanisms and incentives to support households to purchase and install rainwater harvesting systems. This has led to an increase in rainwater harvesting in regional and urban Australia. This review examines the implementation of the regulatory mechanisms a...
متن کاملAn evaluation of measures for improving the quality of roof-collected rainwater
Rainwater itself is free from pathogens and contamination levels of stored rainwater are generally low if tanks are well protected with covers or lids but obvious sources of contamination of the rainwater runoff can originate from faecal matter deposited by birds, frogs, possums, rodents, and dead animals and insects, either on the roofs or in the gutters, or in the water tank itself. A number ...
متن کاملColiforms, biofilms, microbial diversity and the quality of roof-harvested rainwater
Previous studies of the bacterial quality of roof-harvested rainwater have been confined to either detection of specific pathogens and faecal indicator organisms, or epidemiological studies of health effects associated with consumption of stored rainwater. As yet however, a general consensus on tank-water quality has not been reached. In this paper it is proposed that achieving reliable microbi...
