Consultancy Services for Artificial Recharge and Utilisation of the Groundwater Resource in the9 Lesson Learned and Recommendations GCC countries depend on desalinated water for domestic water supply. Emergency reserve in the surface reservoirs and distribution network is 2-5 days. Increasing the storage capacity using surface reservoirs is costly and not environmentally friendly. Groundwater storage using the artificial recharge technique is a promising tool for strategic water reserves in all GCC countries. Storing the fresh water in groundwater aquifers is safer and more reliable in terms of time and location. It is recommended to carry out more extensive studies to evaluate the feasibility of artificial recharge schemes. 10.
