Study on the North China Rural Water Supply Project O&M Cost Standard Rating
For the purpose of further regulating the set-up standard of rural water supply project operation and maintenance cost, OM with North China plain area as the study target, water supply projects at 722 places are selected randomly for study. On the basis of survey data, multiple regression analysis means is employed to analyze relations between O&M cost and operation cost, annual actual output of water supply, personnel cost, electric tariff and water supply facility O&M frequency, and three O&M calculating models are established. O&M cost check computation has high reliability through personnel cost and electric tariff, operation cost and personnel cost, personnel cost and pump, purification equipment, electromechanical equipment, instrument and meter, valve and transmission and distribution pipe network maintenance frequency to some extent. Meanwhile, three O&M calculating models should be selected flexibly in combination with project conditions in actual application.
