Investigation on Sanitation of Centralized Drinking Water Supply in Rural Area of Guangxi in 2006 / 环境与健康杂志

ABSTRACT

Objective To explore the sanitation of centralized drinking water supply in rural area of Guangxi. Methods 400 centralized drinking water supply systems in 33 counties (district) in rural area of Guangxi had been randomly investigated. The field survey on each monitoring site was carried out by investigation form. The water sampling from distribution system and determination were carried out based on the related national standards. Results The rural centralized water supply facility covered 1 170 147 people in this survey. The national and non-national debt project on rural water supply system accounted for 100 and 300 respectively. The rural centralized water supply system with fully and partially treatment (coagulation, deposition, filtration or disinfection) accounted for 48.00%, and those with the fully treatment accounted for 16.00%. The rural centralized water supply systems of national debt projects with fully and partially treatment (coagulation, deposition, filtration or disinfection) accounted for 33.00%, which is statistically higher than those (10.33%) of non-national debt project. The ratio of the rural centralized water supply systems with fully and partially treatment between national and non-national debt project revealed statistically significant difference (P
