| Due to natural, geographical and climatic characteristics, as well as factors such as industrial and agricultural development, the safety of drinking water is increasingly prominent in Liaocheng, especially in its rural areas. To solve the problem,506 rural drinking water projects have been built by 2009 and the access rate to tap water had risen to 87.5%. With the deepening of rural drinking water projects, the popularization and standardization of water supply project construction reach a higher level, and the peasants rely more and more on the tap water. Then, how to manage the projects well to ensure the long-term, safe and efficient operation and to ensure the safety of drinking water in rural areas has become an urgent subject.Based on the study of natural geography, socio-economic condition, water's features, water quality and quantity, as well as the present state of water use in Liaocheng, the author found out the problems existing in construction and management after a comprehensive analysis of the status and features of the projects for rural drinking water safety. The study shows that the projects are large in quantity, small-scaled and dispersed; information management systems should be developed and applied to raise the management level.Hydraulic technology, computer information processing technology, automatic control technology and information communication technology are combined in the development and application of Liaocheng rural drinking water integrated information systems. A strong database is also established in such system which is advanced, practical and easily expanded. With the database the situation of rural drinking water, GIS information, water supply engineering data are analyzed to offer information support for the leadership decision and technical staff. Simultaneously, groundwater level, flow capacity, electric quantity and other running parameters are calculated and transferred, realizing real-time monitoring, so that the management level and work efficiency have been enhanced. The present study provides a good platform for the modernization and standardization of the rural drinking water projects so as to ensure the rural drinking water safety and engineering's long-term operation. |
