The grim situation of water supply in the western region of Handan was considered.Basedon the setting of three diversion routes and the limits of water supply coverage of each line,this paperestablished two water using programs by combining with the mathematical programming model whichminimize the amount of water shortage as the objective function in the total water supply system.Through estimation of the water resources allocation results,and the projects layout and the project investment,the second program was regarded as the best program.It includes transporting water fromJia jiazhuang reservoir to Wu’an county and transporting water from Zhang he river to Wu’an countyand Fengfeng county.The second scheme largely relieve the water shortage situation in the western regionof Handan,such as Shexian,Fengfeng,but for Wu’an city,there is still a large gap betweenwater supply and demand,the sustainable utilization of water resources in Wu＇an city can only dependenton great water-saving.
