Abstract
This technology is to let rainwater flow into a waterway that is located side gutter of a street with blocking garbage including cigarette butts at the same time. The first waterway is located beside the sidewalk and it enhances the water circulation in a city. This waterway is filled with aggregates and filter media, which removes fine dust that is washed out of the street and let water flow down to the earth. The second waterway is located beside the street and it retains rainwater temporarily with decreasing its flow speed. The second waterway shall reduce flooding damages by avoiding bottleneck situation in the street inlets and storm water pipelines which is the main causation of flooding in a city.
