Fuzhou, the provincial capital of Fujian, is a major commercial, industrial, and financial center and one of the high-growth cities in the People’s Republic of China (PRC). Rapid urbanization and economic growth in the city have created serious shortfalls in urban infrastructure services, especially wastewater management. Consequently, large volumes of untreated wastewater were routinely discharged to urban streams. The Min River, an important waterway that passes through the urban heart of Fuzhou and a water source for drinking, irrigation, and industrial processing, became increasingly polluted due to the deterioration in the water quality of upstream local streams and the cumulative effect of numerous point and nonpoint sources of discharge.
The Asian Development Bank (ADB) earlier on helped Fuzhou address the severe water pollution problems by financing the Fuzhou Water Supply and Wastewater Treatment Project, which included the Yangli phase 1 wastewater treatment plant and associated collection networks. However, the capacity of these wastewater collection and treatment facilities was outstripped by the rapidly increasing wastewater generation in the city. In response, ADB approved a loan of $55.8 million for the Fuzhou Environmental Improvement Project in July 2005. The project, together with locally financed initiatives, sought to improve wastewater collection and treatment in the area by rehabilitating and expanding its sewer networks. Its intended impact was improved urban environment and quality of life of the urban residents of Fuzhou. Its expected outcome was reduced environmental contamination in the Fuzhou urban areas and strengthened capacity in water resources and wastewater management.
The project had four components: (i) construction and rehabilitation of Yangli phase 2 sewer networks, (ii) construction and rehabilitation of Lianban sewer networks, (iii) rehabilitation of the inland creeks of Nantai Island, and (iv) development of institutional capacity. Least-cost solutions were incorporated into the design; however, during implementation, the project was affected by changes in the Fuzhou Urban Master Plan and land acquisition and resettlement difficulties, which resulted in sewer network realignments, changes in the number and location of pumping stations, and implementation delays.
Nevertheless, at completion, the project succeeded in achieving its intended results. Project financing of the expansion and rehabilitation of 193 kilometers (km) of new sewers and 2 pumping stations in the Yangli phase 2 network and of 66 km of sewers and 3 pumping stations in the Lianban network significantly helped increase the city-wide wastewater collection and treatment rate to 95% by 2012 from 55% in 2005. Although substantially reduced in scope, the rehabilitation under the project of 5 inland creeks, against an initial plan of 13 creeks, combined with the improvements in the sewer networks to substantially reduce the pollution loads in Fuzhou’s urban water systems and the Min River. Annual average reductions of 10,930 tons of biochemical oxygen demand and 17,960 tons of suspended solids had been achieved, and because of this, the water quality of the urban water bodies had not deteriorated despite significant developments in the area during the project period.
The project’s overall success, notwithstanding the near doubling of its implementation period, from January 2006−December 2009 to July 2006−June 2012, was aided by the improved technical knowledge and project management capacity of the implementing agency staff. Capacity building in project management was largely achieved through consultant support and training programs. However, capacity building in broader sector, technical, operational, and institutional development for related urban services was met to a lesser extent because of discrepancies in institutional arrangements between the actual setup and the one prepared during project design.
The project had the Fujian municipal government as executing agency. It had two implementing agencies: the Fuzhou Water Environment Construction and Development Company for the sewer network components, and the Fuzhou Urban Visual Construction and Development Company for the Nantai Island inland creek rehabilitation component.
