【Abstract】 This paper suggests using daily living waste water to replace tap water for cleaning of Urban roads. Preliminary“change water”schemes and their comparison analysis suggests. That direct waste water supply may be considered as a transitional phase of “change water” for road cleaning in the near future. Intermediate water piping network supply is the direction of water supply towards different water quality for different use, and may be regarded as the development object of medium and distant future. This intermediate water, not only for road cleaning but also for other uses, is an important way to achieve non-drinking water supply.更多还原
