The water storage system within the aquifer,
through the reconstruction of volcanic dikes has
solved the problem of regulation of the water gal-
leries. since 1996, in the canary islands in spain,
are being used on the island of el hierro, and are
currently concluding the work of reconstruction
of dikes on the island of Gomera.
Geo-mechanical systems of regulation ground-
water in volcanic soils encountered in this study,
continue to operate effectively and ensure good
management of water resources.
The systems described in this article can be used
in any volcanic and island system as the archipelago
of hawaii, Macaronesian islands or the Galapagos
islands in south america and many other.

la Gomera (spain), the door has been made by
iPe profiles and metal plates, because this size is
large.
another advantage of this innovation, is that
water is stored in the aquifer, so it is beyond any
kind of pollution and disposal of applications
needed.
There are experiences of this kind of innova-
tion in continental soils, such as a gallery of cuzco
in Peru, but these have the following features, in
speaking of a sedimentary.
Drainage galleries in Peru are very similar to
the canary islands in spain, although those in
sedimentary soils in Peru, geological features, have
focussed on exploitation of groundwater into sedi-
mentary rock (sandstone) fractured, although there
are work experiences highly fractured volcanic
rocks. Water galleries have been built with a section
of 2 × 2 m and the methodology has been the con-
ventional drilling using a pneumatic drill powered
by compressed air supplied by an air compressor,
unlike drilling for explosives in the canary case.
The sealing of the dike system in Peru is not
as large as the dimensions of the case in the
canaries.
