Tongxu County is a severe water-deficient area with poor supporting facilities in the field. As a result, it is difficult to use water in the irrigation area. Therefore, it is necessary to conduct irrigation and water diversion and supporting facilities in the project area. In the project area, 1 branch pipe is planned for excavation and dredging, 4.0 km in length and 6 in Douonou, 9.8 km in length, 1 new sub-sluice and 22 new bridges. It is required to complete 89,000 m3 of earthwork and 970 m3 of concrete with planned investment 1.3 million yuan. After the implementation of the project, the guaranteed rate of irrigation in the project area will be increased by 30%, the irrigation area will be improved to 730hm2 and the area for waterlogging improvement will be improved to 911hm2. The per capita income of farmers in the project area will increase by 200 yuan. The project is technically feasible, economically reasonable and has significant economic and social benefits. It is proposed that the project should be implemented as soon as possible so that it can exert its benefits as soon as possible.
