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).

•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

•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
