Economic development and population growth have deeply damaged the urban water environment of Guilin City, China. Main problems involved structural damage and functional deterioration of the urban waters. An integrated technical scheme was developed to rehabilitate the urban water environment and to enhance the waters' functions during 1998-2008. Improvement of waters' functions included water system reconstruction, water pollution control, water safety assurance, and aquatic ecological restoration. The water system was reconstructed to connect different waters and clean water supplies to the lakes. Moreover, water pollution was controlled to improve water quality by endogenous pollutant elimination and extraneous pollutant interception. In addition, ecological measures put in place serve to enhance water 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.
