| One of the major issue about roof-harvested rainwater is physicochemical and microbiological contaminations of this water and their negative impacts on human health for potable and non-potable usage. Different factors can directly or indirectly affect the quality of roof-harvested rainwater such as: The climate of the region in terms of volume and intensity of rainfall, material and architectural of roof, type and concentration of air pollutants and etc. Extensive studies have been conducted on this subject in different countries although sometimes their target was not to solve the problem of water shortages, but also to help control runoff. In Iran despite the importance of the issue from both perspectives of water supply and flood control, limited studies was performed. Therefore this paper studies the physicochemical and microbiological properties of roof-harvested rainwater and its influencing factors. As well as solutions presents to re-use this water for drinking and non-drinking consumption and finally, recommendations have been proposed according to the different regions of our country. |
