Discussion
• How each sector gets its water
• Best combination of alternatives.
![Page 15: Present and Future Water - WSTA GCC · 2020. 3. 8. · Present and Future Water Supply and Demand in Saudi Arabia Prof. Abdulaziz S. Al-Turbak Civil Engineering Dept. College of Engineering](https://reader033.vdocuments.net/reader033/viewer/2022051811/6028a27f74e2e96b6b74fa1a/html5/thumbnails/15.jpg)
Major Problems
• Demands in Agricultural Sector.
• Meeting Future Needs for Urban Areas
and Industry.
• Limited Use of Treated Wastewater.
• Development of Renewable Water
Resources
![Page 16: Present and Future Water - WSTA GCC · 2020. 3. 8. · Present and Future Water Supply and Demand in Saudi Arabia Prof. Abdulaziz S. Al-Turbak Civil Engineering Dept.

Suggested Solutions
• Reduction of Irrigation to a Safe Level.
• Conservation of Water.
• Priority for More Wastewater
Collection, Treatment and Reuse.

• Extend Area where Pumping of
Groundwater is Prohibited.
• More Projects to Increase Supply of
Desalinized Sea Water (with Reduction
of Costs).
• Develop Areas with Renewable Water
Resources.
