When drained off to the water body, municipal domestic sewage has severely affected the use performance of water resources. However,because of the shortage of water,afforestation in many places in desert region has failed.This paper puts forward a tentative plan about diverting municipal domestic sewage to irrigate the afforestation nearby.And,it compares this new plan with the traditional one through economic and environmental effects.The result shows that the new plan occupies a dominant position.
