Abstract: The management of rural drinking water projects is a hotspot in the research on rural water supply projects, while the management mode of small-scale projects receives less attention. It ' s of great importance to establish an effective evaluation mode for the management of small-scale drinking water projects. By investigations in Zhejiang province, small-scale drinking water projects at present are found to be mainly managed by the village collectively, by the water-users association, and by responsibility contracts. An extensible evaluation for the qualification degree of the management modes is presented and is applied in the extensible analysis and decision-making in the purpose of studying the correlation among the evaluation indexes by constructing correlation functions. Fifteen projects in Liandu district of Lisui municipality in Zhejiang province are evaluated to prove the feasibility of the method.
