Southern Bekaa Irrigation Project

It currently irrigates 2,000 hectares from Qaraoun Lake in the south to Jib Jenine and Kamid Al Lawz in the north. Upon completion, it will irrigate approx. 21,000 hectares.

 

  • The first phase, including hydraulic infrastructure was executed between 1998 and 2001, using state-of-the-art irrigation techniques.

 

 

  • The 2,000 hectares area dedicated for the project is divided into 3 irrigation districts, among them the following real estate zones:

Project Facilities

  • The project is composed of:
    • A main water channel (Canal 900) extending over 18.40km
    • A main pumping station at the bottom of the Qaraoun dam
    • Secondary pumping stations of well networks
    • Distribution reservoirs and artesian irrigation networks
  • Most of the water used in irrigation comes from the Qaraoun Lake with support from the wells in Kamid Al Lawz for Jib Jenine

The Way It Works

  • The Authority uses synchronized, integrated automatic hydraulic operations for pumping, hauling and distribution facilities, depending on the demand on water from farmers. Water comes from the water spring on the outer distribution network that works with upward compression to balance reservoirs and secondary pumping stations in every irrigation district, then to Canal 900 and from there to the main pumping station at the foot of Qaraoun Dam.

  • The main pumping station at the foot of Qaraoun Dam provides an average flow of 4.5 m3/s at a pumping height of 76m, using the main propelling water pipe until Canal 900 which drains around 4.5 m3/s over 18.5

  • Water is hauled to every irrigation district through a secondary pumping station from Canal 900 to the secondary balance reservoir at the height of 951m, and then to the distribution network via underground compressed water pipes, which in turn feed the water springs with many outlets, including drainage and compression plugs, as well as a meter to facilitate distributing water in accordance with the demand.
  • The role of the 3 balance reservoirs is to provide water in case of difference between the variable drainage required by distribution networks, and the minimum fixed drainage provided by secondary pumping stations..
  • Kamid Al Lawz field is composed of five wells which are used for direct pumping to the fourth basin from Canal 900, with an individual average flow of 55L/s, the equivalent of an overall flow of 275 L/s.
