Artificial Storage and Recovery (ASR)

Why Artificial Groundwater Recharge?

Arid climate zones require an optimized usage of the water resources.

� Water supply and demand patterns do not fit.

� Water supply schemes may fail, backup is needed.

� Water storage in dams causes high evaporation losses.

� Water storage in tanks is very costly.

� Artificial Storage and Recovery (ASR): Surplus water is stored in an aquifer and recovered when needed.

� Applications:

� Seasonal Storage.

� Balancing of Peak Demand.

� Strategic Resource for Emergency Case.

• Climate-related scenarios (floods, lack of rainfall, storm damage)

• Earthquakes• Facility-related incidents (chemical plants, reactors,

accidents at sea)• Major breakdowns in waterworks• Epidemics• The impacts of war• Terrorist attacks
