Water scarcity in the Middle East
What can be done? Improve water management by:
• Efficient water use • Groundwater conservation • Adequate water tariffs • Creating new water sources (reuse and desalination)
Desalination plays and will play a critical role in the future water supply for Middle Eastern countries

Case study: Optimized power consumption in Chennai
Desalination plant in Chennai (100 ML/day)
• Specific Power: 3,51 kWh/m3
• Power Ratio Average Aug’12 to Jan’13: 2,55 kWh/m3
• Power Saved: 27% • Power Saved between Aug’12 and Jan’13: 14.688 MWh • CO2 saved between Aug’12 and Jan’13: 8.761 Ton. CO2

Keys to solar driven desalination
• MENA region has huge potential to produce solar energy
• Solar energy is more predictable than most of other RE sources1
• RO, CSP and PV are scalable technologies • Level of technological development (relevant advances
have been done to address this challenge) 1 PRODes 2010
