    ANALYSIS OF WATER SUPPLY SAFETY OF GROUNDWATER SOURCE AREA IN SHIJIAZHUANG URBAN DISTRICT OF HEBEI PROVINCE

    • Groundwater is the main water supply source of Shijiazhuang city for many years. But, as the reinforcement of the Huangbizhuang reservoir auxiliary dam, a project to control the reservoir leakage, the groundwater side recharge from the reservoir seepage, as a part of total groundwater supply for Shijiazhuang city, is largely cut off by the auxiliary dam. This results in a new problem of water supply safety of riverside groundwater source. This paper described the history and present condition of groundwater exploitation and utilization in Shijiazhuang city, analyzed the auxiliary dam reinforcement how to affect the groundwater of lower head area, and also analyzed the situation of supply and demand for water resources in the near future. According to designing frequency of precipitation, the water levels of all the wells which belong to groundwater-pumping plant No.4 and No.7 were calculated. Furthermore, on the basis of safety analysis for the main water supply wells of groundwater source, a assessment of water supply safety is gained through designing the safety stages of wells.
