Adapted management model:
•Water Users Association (WUA) responsible for water
management distribution and, direct supervision of the
Municipality
•Overall supervision of the MoA (to which the reservoirs
were handed over).
•Water flow meters per farm.
Payment model:
The WUA collects the cost per cubic meter, then pay to the
water source (wells owners).

Considerations and lessons learnt
•Involvement and participation: community,
government, local authorities, NGOs..etc
•Inclusive
approach:
social,
economical,
production and environment (not just a reservoir)
•Integrated approach: technical, economical,
demand/supply management , services, quality
•Accountability and transparency: vis a vis
beneficiaries and actors (MoA, NGOs, local
authorities..etc)
•Adaptability
and
flexibility:
for
future
opportunities/constraints at all levels
13. FAO Emergency and Rehabilitation Office – WBGS
Considerations and lessons learnt (Technical)
•Volume of reservoir to fit with available water (pumping rate per
hour and pumping intervals), water distribution scheme and
irrigation area, discharge and refilling rates (sustainable and
continuous).
•Site of the reservoir to guarantee pressure of at least 2 atm. (at
least 20 meters higher than the nearest plot to be irrigated).
•The flow must be calculated and the curves, valves, etc. to be
taken in to consideration as well as the fraction lose from/ to the
feeding/irrigation pipes.
•The welling of farmers to participate and payback the cost of
used water.
•Good management plan and water distribution scheme.
•At least two water sources (example: 2 wells to feed the
reservoirs)
•In case of many reservoir units to be linked together, each
reservoir unit to be assembled also as an independent unit
Notas do Editor
Problems:
low productivity per unit area (less than 0.3 tons per dunum),
high cost of irrigation water per cubic meter (USD 4/cubic meter),
Monocrop cultivation type,
land and water resources were inaccessible to poor farming households.
Problems
low productivity per unit area (less than 0.3 tons per dunum),
high cost of irrigation water per cubic meter (USD 4/cubic meter),
Monocrop cultivation type,
land and water resources were inaccessible to poor farming households.
Problem solved:
converting rained plains of 400 dunums to irrigated open and protected vegetables cultivation.
Reduced cost of irrigation water per cubic meter (less than USD 1)
Increased productivity up to 6 tons per dunum.
Crop rotation and diversification were enabled for maximum profit margin.
Land and water being cultivated and accessible for poor household families.
For the reservoirs in Tamoun: works inluded: 2 KM of main steel pipes, fittings, accessories, elbows, filters, flanges, and other irrigation devices including 4 units reservoirs having total capacity of 1470 cubic meter with total costs = USD 87000 for 400 dunums, out of which USD 43000 were allocated for the 2 km piping. In summary, 120 beneficiaries benefited at USD 725 / farming family.
