New Technology Used in Water Saving Rehabilitation Engineering of Weishan Irrigation District

The Weishan irrigation district is the largest irrigation district in the lower and middle of the Yellow River. It is a lifeline of economic development of Liaocheng and North China. From 1998 to 2006,there were 308 new multifarious buildings were constructed to ameliorate the engineering condition of the irrigation district. In this paper,the method of data analyzing were used and basic situation of water saving rehabilitation project was introduced,the new technology and materials used in the engineering were summarized,rehabilitation benefit was analyzed,it tried to use for reference to other irrigation districts.
