Main problems involved structuraldamage and functionaldeterioration of the urbanwaters. An integrated technical schemewasdeveloped to rehabilitate the urbanwater environment and to enhance thewaters＇ functionsduring 1998-2008. Improvement ofwaters＇ functions includedwater system reconstruction,water pollution control,water safety assurance, and aquatic ecological restoration. Thewater systemwas reconstructed to connectdifferentwaters and cleanwater supplies to the lakes. Moreover,water pollutionwas controlled to improvewater quality by endogenous pollutant elimination and extraneous pollutant interception. In addition, ecological measures put in place serve to enhancewater system functions and better benefit both nature and humans. The project has brought about sound ecological, economic and social benefits in Guilin City,which can potentially be extended to similar cities.展开更多
