Effect of roof materials and weather patterns on the quality of harvested rainwater in Shanghai, China
Abstract
Abstract As the supplementary of domestic water and even as potable water, roof harvested rainwater seems increasingly probable worldwide due to the shortage of fresh water resource. In this study, we compared the quality of harvested rainwater under different meteorological conditions and roofing materials (i.e., galvanized metal, ceramic tile, concrete and asphalt). Results showed that the quality of roof harvested rainwater in the rainwater tank was superior to the first-flush tank, but reusing directly without diversion was not recommended. Compared with other three roof types, ceramic tile was ideally qualified for roof rainwater harvesting, which achieved the highest quality of recycled rainwater (e.g., turbidity (5.03\xa0±\xa01.73 NTU), TOC
