Why Drip Irrigation? Why not ?
Water is applied directly to the
crop ie. entire field is not
wetted
Damage to components
Water is conserved. Water quality and emitter
clogging
Slow rate of water application
somewhat matching the
consumptive.
Economic considerations
Weeds growth is controlled. Contraction and expansion
The evaporation is less.
6. Drip Irrigation
• The project was targeting
small scale farmers 4 to 6
dunuams.
• Drip irrigation system is
considered as low
pressure system. High
pressure can blow out
point source emitters and
have an erosive effect on
drip lines and other
components.

• Pressure regulator.
• Main pipe PE (2.5
inch)
• T connecter
• Pipe cap
• 16 mm pipes and
emitters(emitter
every 20 cm or 30
cm)
• Plastic tap.
• Pipe drill camp
• Water filter with
mesh inside.

Designing Considerations
• Pressure and flow rate. The greater the flow rate, the
greater the required inside diameter (ID) to minimize
pressure differences between outlets caused by
friction.
• Pump selection.
• Drip laterals should be kept as short as practical to
minimize pressure loss due to friction. (Ideally)
• System capacity and maximum daily irrigation
requirement. (the peak water requirements of a
vegetable garden)

Recommendation
• It’s recommended to purchase from Syria, when it’s
available.
• It’s recommended to deliver a Guideline for the
farmers including the main technical and maintaining
information in order to save the system efficiency as
much as we can.
• It’s recommended to encourage drip irrigation
system particularly within such a drought problem.
• It’s recommended to keep the system in appropriate
place during winter to the next season.

Lesson Learned
• Include fertilizer injector.
• Set of irrigation scheduling plan.
• Ihsan carried out an international tender, in order to
purchase drip irrigation equipment. The winner bid
was a Turkish company. Therefore, some
maintenance equipment may will not available in
Syria.

The greater the flow rate, which is determined by the sum of the flow rates of all outlets downstream of a particular pipe section, the greater the required inside diameter (ID) of that pipe section to minimize pressure differences between outlets caused by friction
