水是一切有机体的主要组成部分,全球动植物和40亿人体内含有约11200亿吨水。人类社会依赖水而生存发展。古代,人类对水取利避害,适应水而生存;近代,人类对水兴利除害,兴建工程,开发水利,控制水害;现代,随着社会和生产的发展,地球上可资利用的水日趋短缺,水体受到污染,严重影响人类生存的环境,人类逐渐认识到水是一种重要资源和环境因素,从而在更高的水平上开始对水开展了新的兴利避害活动。
世界气象组织1996年初指出:缺水是全世界城市面临的首要问题,估计到2050年,世界2/3以上的人口将生活在城市,而全球有46%的城市人口缺水,必须平衡社会经济发展和城市淡水供应管理二者之间的关系,进行水资源的储存、输送和管理的大规模工程建设。
