前  言
科学推进饮用水安全,创造良好的生产生活基础,是人民对美好生活的基本需要,也是城乡基础设施协调发展的重要体现。
坚持节约资源和保护环境的基本国策,要求我们节制地取用水,以减轻对自然环境的干扰。但是,自工业革命以来,科学技术的发展使人们改造自然、攫取资源的能力得到前所未有的提升,于是市场化、产业化、人口剧增带来了对水资源的过度消费和大量浪费,水资源水环境问题日趋严峻,建立健康的水循环体系迫在眉睫。
在水的社会循环中,如果将人们聚居生活的社会区域拟人化,供水管道系统好比人体的动脉,排水管道系统是静脉,而给水处理厂、污水再生水厂及其配套的泵站系统共同构成人体的心脏。如同动脉、静脉和心脏协同保障人体健康的血液循环,供水系统向城乡社会输送优质饮用水,是保障社会运行的关键。由此可见,城乡供水系统是重要的民生工程,是经济社会发展不可替代的基础支撑,是生态环境改善不可分割的保障系统。党的十九大报告提出,推进资源全面节约和循环利用,倡导简约适度、绿色低碳的生活方式,为实施城乡健康供水提供依据和政策。
