A Study on Comprehensive Benefits from Drinking Water Improvement in Rural Areas of Xinjiang Autonomous Region

The project of drinking water improvement greatly ameliorates drinking water conditions and reduces waterborne infectious diseases in rural areas of Xinjiang, where the habits of farmers and environment are varying gradually but profoundly. A dynamic quantitative analysis is made on the direct economic benefits from the convenience in drinking water intake, the saving of medical fee, the family economy, and the waterworks.
