This course has been created to acquaint the
reader with the topic of Aquifer Storage Recovery.

Aquifer Storage Recovery.”
Aquifer Storage Recovery (ASR) is the storage of
water in a well during times when water is
available, and recovery of the water from the
same well during times when it is needed. ASR
provides a cost-effective solution to many of the
world’s water management needs, storing water
during times of flood or when water quality is
good, and recovering it later during emergencies
or times of water shortage, or when water quality
from the source may be poor.
Large water volumes are stored deep
underground, reducing or eliminating the need to
construct large and expensive surface reservoirs.
In many cases, the storage zones are aquifers
that have experienced long-term declines in water
levels due to heavy pumping to meet increasing
urban and agricultural water needs. Groundwater
levels can then be restored if adequate water is
recharged.
