Objective To investigate and evaluate the comprehensive benefits of water and fluoride reduction projects in the province and to guide future water diversion work. Methods A total of 200 projects involving water improvement over 6 years were randomly selected to investigate the main food production and cash income of dental fluorosis, urinary fluoride and benefited village children aged 8-12 years. Results Persistent use of fluoride water in drinking water during the year showed a significant drop in the rate of dental fluorosis in children; the economic income of residents increased significantly compared with that before water change; and the annual increase of cash income in 260 villages was 33.11 times of the total investment in water diversion projects. Conclusion It is necessary to strengthen the management and maintenance of the water diversion project to obtain good benefits. It is very necessary for the public to educate the masses to raise their awareness of the dangers of high fluorine. It is necessary to study and formulate scientific, reasonable, accurate and easy-to-use evaluation indexes
