埃及的经济发展和各发展部门的快速增长取决于水资源的可获得性。埃及转而使用地下水来满足日益增长的需求，代价是超过安全产量，过度开采尼罗河三角洲西部和尼罗河流域沙漠边缘等一些地区的含水层系统。埃及灌溉水源的短缺带来了非常规水资源的使用问题。作为地下水资源环境管理的一部分，埃及启动了一项研究人工补给以增加地下水供应的可行性的方案。通过这项计划，对利用处理后的废水进行人工回灌试验的调查和潜在选址进行了详细的研究。经过污水处理后的含水层人工回灌是一种可以在埃及应用的新工具，与直接使用相比，可以安全地使用污水。通过含水层土壤(非饱和区)，增加高级污水处理阶段，去除大部分生物负荷，并发现一些化学物质的浓度可以部分降低。本文以阿布拉瓦什农场为例，介绍了用于技术环境评价的含水层蓄水初步水文地质调查和试验方案。除应用环境影响评价(EIA)进行人工回灌试验外，还对未来回灌项目的可行性进行了评估。结果表明，利用处理后的污水对地下含水层进行人工补给是很有前途的，需要更详细的研究来评价含水层特性对处理后污水补给机理的影响。由于含水层中普遍存在的物理和化学条件的变化或由于有限的吸附能力以及微生物存活和有毒污染物的降解而造成的健康风险。
The economic development in Egypt and the rapid growth rate in various development sectors are dependent on the availability of water resources. Egypt has turned to use the groundwater to satisfy the growing demand, at the expense of exceeding the safe yield and overexploiting the aquifer systems in some areas such as western Nile Delta and along the desert fringes in the Nile Valley. Shortage of irrigation water sources in Egypt bring out the issue of using non-conventional water resources. As a part from the Environmental Management of Groundwater Resources, Egypt launched a program to examine the feasibility of artificial recharge for the augmentation of groundwater supply. Through this program a detailed study has been carried out for the investigation and potential site selection for carrying out an artificial recharge experiment using treated wastewater. The aquifer artificial recharge by treated sewage water is a new tool can be applied in Egypt for using the sewage water safety compared with the direct use. Through the aquifer soil (unsaturated zone), advanced sewage treatment stage will be added by which most of the biological load will be removed and partially reduction in concentrations of some chemicals can be found. This paper presents the preliminary hydrogeological investigation and tested scenarios for the aquifer storage which used to evaluate the technical environmental, consideration in Abu Rawash farm as a case study. In addition to applying environmental impact assessment (EIA) of artificial recharge experiment to assess the feasibility guidelines for the future recharge projects. Results indicated that artificial recharge for groundwater aquifer using treated wastewater is promising whoever it needs more detailed study to assess the aquifer feature influences the mechanism of recharge with treated wastewater. The health risk due to changes in the physical and chemical conditions prevailing in the aquifer or due to limited adsorption capacities as well as the microorganisms survive and toxic pollutants degradation.
