During the past 7 years, NGOs as well as governmental
agencies carried out many experiments with underground dams in the State of
Pernambuco. Currently there are about 500 of these underground dams in
operation, as well as another 500 built by technicians. The largest dams have a
depth of 10 m and they can hold about 80.000 m3. This volume is
large enough to assure provisions for up to 500 families, or provide irrigation
for 15 ha. This paper deals with the potentials of this type of water reservation.
