 With a long-standing
involvement in the supply of
water, FARAZAB has designed
and supervised the
construction of several
dams. FARAZAB dam
department, traditionally
active in dam engineering,
has been responsible for the
design and construction
supervision of more than one
hundred dams. FARAZAB has
designed several different
earth fill dams with clay
cores, that also serve river
regulation and irrigation
purposes.
Earth fill dams.
Geological and seismological
studies.
Geotechnics
and foundation
treatment.
Soil conservation &
watershed management.

Shahid
Ghanbari Reservoir
Dam and
irrigation/Drainage
Network:
Client:
west_azarbijan
regional water
company
Location: NW if
iran,9km NW of Maku
in west_azarbijan
province
Scope: regulate and
store 28.8 MCM
annual flow of Sari_
Su river to optimize
irrigation potential
as well as
development and
improvement of
irrigation/drainage
system in 5,000 ha
in shahid ghanbari
plain farmlands.
in this project
Sari_ Su river flow
is diverted by a
levee and
transferred to the
ghanbari reservoir
dam through a 4 km
length canal. the
dam has been planned
and constructed to
regulate all the
river discharged and
enhance the
irrigation potential
to regulate all the
river discharged and
enhance the
irrigation potential
in the plain. 29 MCM
water potential
created by these
establishments will
be come together
with approximately
12.3 MCM annual
volume of present
springs in the
plain.
these amounts of
water will be used
to develop 1750 ha
and improve 3250 ha
of the downstream
farmlands.

water supply of
Golfaraj, Gordian,
Yekanat and
Harzandat Plains :
client: East_
azarbijan and
ardabil regional
water authority
Location: NW of
iran,10 km from
jolfa in east_
azarbijan province
Scope: water supply
and irrigation of
Golfaraj, Gordian,
Harzandat and yekant
plains (25,000 ha)
via establ ishment
of pumping systems
to take the water
from aras river,
transfer and store
it in four separate
reservoir dams along
with developing
relevant irrigation
and drainage network
in the plains.
The dams and related
reservoirs have been
considered to
regulate the pumped
volume to reduce the
required maximum
capacity of pumping
and transferring
system and
consequently project
costs.
Project components:
pumping stations,
transferring system,
golfaraj dam,
gordian dam,
harzandat dam,
yekanat dam,
irrigation and
drainage network
