In the recent past there has been an alarming rate of depletion of groundwater resources in the aquifers of the Kingdom of Saudi Arabia primarily due to agricultural, urban and industrial water requirements. Currently, there is as much as 14 billion m3 of non-renewable groundwater being utilized in the Kingdom each year. It is estimated that the present 1 billion m3 of wastewater effluents generated by the cities of the Kingdom per year will increase to approximately by 1.5 billion m3/yr by the year 2000. A comprehensive feasibility study to utilize the wastewater effluent from the city of Dammam to recharge an aquifer nearby is envisaged. The preliminary results of this study and economic considerations strongly favor the undertaking of large scale recharge projects to replenish the depleting water tables in the Kingdom with secondary effluents.
