It is used mostly as non-potable water for such purposes as toilet flushing and clear streamflow restoration. Only less than one percent of recycled water is used in Japan. Against such a background, sprinkling advanced treated wastewater (recycled wastewater) over water-retaining pavement in the hope of helping clean the road surface(cso) and alleviate urban heat island phenomena has been gaining greater attention as a new application of recycled water. In this study, the expected effects of recycled wastewater sprinkling and the problems involved in sprinkling such as odors were verified by conducting field tests, and the feasibility of sprinkling recycled wastewater was examined.
