Abstract
In view of the high altitude,complex and diverse forms of rural water supply,the scattered layout of villages,the large height difference of terrain in water supply benefit areas in Guizhou Province,the water supply could not be ensured,and the quality of water supply are different.In the paper the design principle of large-scale water supply system and the design idea of water rationing in the benefit area are put forward.It is proposed to adopt scientific selection of water sources,water supply site and the optimization of the water supply pipe network to meet the adequate water pressure at each site in the benefit area,so that the large-scale water supply system could be realized in the benefit area,the reliability of the water supply system could be improved,the construction investment could be cut down,and the operation and management cost could be reduced.The method of water rationing could not only improve the reliability and flexibility of water supply system,but also reduce the pressure of operation and management,and realizes stable water supply.关键词
