Credit: IDA standardterms with 35 years maturity. Objectives and Desaiption: The project would control floods and improve land drainage in China's most industrializedand highly productive agricultural area. The project would also improve the quantity and quality of raw water for the ShanghaiCity water supply, and expand and improve inland waterway transportation. Flood control and land drainagewould be effectedthrough river channelizationof the Wangyu and Taipu Rivers to evacuate flood water to the YangtzeRiver, flood diversionthrough the Hang-Jia-Huriver system to Hangzhou Bay, and increased flood regulation in Tai Lake through strengtheningand upgrading of the lake's perimeter dikes. The enlarged Wangyu River channel would be used to divert water from the Yangtze River to augmentwater supply in the basin during dry seasons. Inland waterway transportationwould be improved through more stable and controlledwater levels and additional shiplocksconstructed in rivers and canals. Institutionalcapability would be strengthenedthrough better facilities for flood monitoring and forecasting, communication, staff training, technicalassistance, and equipment. Benefits and Risks: The main benefit is preventionof flood damage and losses. The cost of long-termannual averageflood damageand losse that wouldbe prevented is estimated at $77.6 million. The improved drainage on 86,000 ha of cropland would provide annual incrementalproduction of 43,000 tons of grain and rapeseed valued at about $4.5 million. Other benefits, not readily quantifiable, include: (a) enhanced quantity and quality of raw water for Shanghai's polluted water supply; and (b) improved and expanded inland waterway transportationwithin the Taihu Basin. The project faces no significanttechnical risks. The engineering concept is sound and the solutions have been derived after years of studies and This document has a restricteddistribution and may be used by recipients only in the performance of their officialduties.

The effects of any unprecedentedflood exceedingthe designed value would be substantiallyreduced by the project works and through flood forecastingsystem and contingencyplans to be provided under the project. Organizationaland institutionalrisks would be compensatedby staff training in project implementationand management.
