The Document No.1 of the Central Government in 2011clearly put forward "improve the optimization strategy of water resources allocation pattern, under the precondition of ecological protection, as soon as possible a group of backbone water engineerings and water system connecting engineerings between lakes and rivers is built and improve the ability of regulation and control of water resources and water supply security". In this paper, based on the current main problems of rural water systems, by analyzing the necessity of the construction of rural water system connecting engineerings, the technical requirement of rural water system connecting engineering construction is proposed. It can be referred for similar engineerings.
