Summary of the GCC Water Sector Assessment Report (Report No.: 32539-MNA)

Core Content

This report, prepared by the World Bank in collaboration with AGFUND, presents a comprehensive assessment of the water sector in the Gulf Cooperation Council (GCC) countries. It highlights the challenges and opportunities in managing water resources in the region, emphasizing the need for sustainable and efficient water use, institutional reforms, and public-private partnerships.

Main Challenges in Water Resource Management

1. Unsustainable Use of Groundwater Resources

• Groundwater is heavily relied upon for irrigation and domestic use.
• Over-abstraction and mining of groundwater are leading to its rapid depletion.
• In Saudi Arabia, non-renewable groundwater in deep aquifers is a significant resource but is rapidly depleting.

2. Lack of Urban Water Demand Management

• Urban water demand is increasing rapidly due to population growth and high per capita consumption.
• Per capita water consumption in the GCC is among the highest globally, ranging from 300–750 liters per day.
• Demand management is largely neglected, and price signaling is minimal, leading to wasteful use.

3. Institutional and Legal Constraints

• Water institutions and legal frameworks are not fully equipped to manage the growing water demand.
• There is a lack of effective policies to promote conservation and efficient water use.

4. Limited Private Sector Role

• Although the private sector is being encouraged, its involvement remains limited.
• Existing contracts and management structures often fail to provide incentives for operational efficiency.

Key Policy Recommendations

1. Adopt Integrated Water Resources Management (IWRM)

• Promote a holistic approach to water management that integrates all sectors and stakeholders.

2. Enhance Urban Water Demand Management

• Implement effective demand management strategies and improve water pricing mechanisms to signal the true cost of water.
• Expand water metering and billing to all users, including nationals, to promote conservation.

3. Achieve Sustainable Aquifer Management through Irrigation Water Demand Control

• Focus on reducing irrigation water use through better technologies and policies.
• Encourage the use of treated wastewater for irrigation to reduce pressure on groundwater.

4. Conduct Institutional Reforms for Sustainable Water Resources Management

• Strengthen the capacity of water-related institutions.
• Promote legislation that supports water conservation and efficient use.

5. Strengthen Public-Private Partnerships (PPPs)

• Encourage private sector participation in water and sanitation projects.
• Develop transparent and accountable frameworks for PPPs to ensure efficiency and cost recovery.

6. Enhance Water Supply Management

• Improve the efficiency of desalination and wastewater treatment technologies.
• Invest in the rehabilitation of aging desalination plants and the construction of new wastewater treatment facilities.

7. Expand the GCC's Coordination Role for Improving Water Resources Management

• Strengthen regional cooperation to address shared water challenges.
• Develop a unified approach to water policy and management across GCC countries.

Key Information

Economic Context

• The GCC countries are heavily dependent on oil revenues, which have enabled significant infrastructure development and improved living standards.
• Oil accounts for about a third of total GDP and three-fourths of government revenues and exports.
• High oil revenues have led to the subsidization of water services, which may become unsustainable in the future.

Water Resources Overview

• Annual freshwater resources per capita in the GCC range from 60 to 370 cubic meters, making these countries among the least water-endowed globally.
• By 2030, per capita freshwater resources could fall to about 94 cubic meters due to population growth.

Desalination and Water Supply

• Desalination is the primary source of water supply, with Multi-Stage Flash (MSF) being the most common method.
• Reverse Osmosis (RO) is becoming more competitive due to technological advancements and cost reductions.
• Average water production costs in the GCC remain between US$1.0 to 2.0 per cubic meter, which is significantly higher than in other regions.

Wastewater Management

• Wastewater treatment and reuse coverage is limited, with most treated water being used for landscaping or lost to the sea.
• Treated wastewater is being piloted for groundwater recharge and agricultural use, but with caution to avoid negative impacts on water quality and public health.

Fiscal and Environmental Implications

• Heavy water subsidies are placing a significant burden on national budgets and may not be sustainable.
• The fiscal burden could reach up to 10% of oil revenues by 2025.
• Environmental issues such as saltwater intrusion and groundwater contamination are becoming more pronounced due to overuse and poor management.

Conclusion

The GCC faces significant water challenges due to its arid climate, rapid population growth, and high per capita consumption. While desalination is the backbone of the region's water supply, it is not a long-term solution without improvements in demand management, institutional reforms, and increased private sector involvement. The report emphasizes the need for sustainable water policies, regional coordination, and efficient use of resources to ensure future water security and economic stability in the region.
