In order to alleviate the current situation of the water shortage in western China, on the basis of analysis and discussion of water diversion project proposed by the predecessors, following the principles of the shortest water diversion line and abundant water resource , the paper put forward that 7×108 m3 of water should be transferred annually from upstream of the Brahmaputra river to Xinjiang. Water consumption of the receiving area was allocated, water diversion routes and the scale of the project were planned, the main building dimensions of the water conservancy hub were preliminary designed and the project investment was estimated. This program avoids other water transfer lines passing through the national nature reserve, and intends to restore the ecology of the downstream of Tarim River and alleviate the water shortage in the southeast of Xinjiang. It is a highly feasible water diversion project.
