Non-conventional water resources in Bahrain consist mainly of desalination and treated municipal wastewater. Industrial wastewater and irrigation drainage water do exist, but their volumes and utilization are relatively minor.

The combination of high population growth and exhaustion of water resources has contributed to a water crisis that may be one of the most catastrophic the world has ever seen

The amount of water that is technically and economically exploitable is 80% of current available resources. This reveals the constraints on water resources and the challenges that lie ahead regarding the urgency of an integrated management approach.

Renewable water resources in Algeria are estimated at approximately 19 billion cubic metres per year (BCM/yr) (Table 1), approximately 450 cubic metres (m3) per capita per year. This is below the recommended 500 m3 per capita per year

The water infrastructure in Algeria includes 80 dams , 8800 boreholes, 11 desalination plants, 21 transfers (upstream and downstream of dams) and 100 Water treatment plats

Rain is the main water resource in Syria, affecting the availability of all other water resources. The average annual rainwater resource is estimated at 46 billion cubic metres (BCM).

The Middle East Desalination Center (MEDRC), headquartered in the capital Muscat, was founded in 1996. MEDRC is working in alignment with the government strategy to address significant regional or transboundary environmental challenges. Furthermore, it plays a significant role in boosting water-related research and innovation in Oman

About 98% of Egypt’s fresh water resources originate outside of its borders, such as the Nile River and groundwater aquifers. Indeed, the Nile River provides the country with some 93% of its water requirements

Water in Egypt is vulnerable to three main risk factors: High pollution and increasing water costs as a result of pumping water over and over again and without treatment.

groundwater is the main water resource in Oman used for domestic, industrial and agricultural purposes.
