The rising groundwater levels in Ajdabiya city have been considered one of the critical issues that the city suffered for years, where it is attributed to a lot of undesirable environmental and physical effects. Deterioration of infrastructure facilities led to health and economic consequences in different areas. The study aims to identify the causes of effects and feasible strategies to mitigate them. There are many causes that led to rising the groundwater level such as the leakage of domestic water pipeline and sewage network. It noted an absence of a rainwater drainage network and the adoption of only surface water for daily life usages. Furthermore, never ever the groundwater has been not exploited, which led to upward seepage more and more. Ten groundwater samples have been collected to conduct specific criteria which proved the mixing between the groundwater and sewage. Many projects can be adapted to maintain the groundwater upward seepage and manage the water supplies in the area using the conjunctive use of groundwater and surface water to optimize the water demand. The most important is avoiding all pollutants whether surface or/and subsurface by maintaining the sewage network and drainages. For a more comprehensive image, it is recommended to adopt geotechnical tools before suggesting the management plan
