  • Hashemite Kingdom of Jordan

    Ministry of Water and Irrigation

    Groundwater in AZRAQ Basin

  • JORDAN : FOURTH DRIEST COUNTRY IN THE

    WORLD

  • Jordan is an arid to semi arid country

    An area of about 90.000 km2.

    A population of 6 million.. Annual growth

    rate of about 2.2 %

    High flow of refugees from surrounding

    countries adds burden to water supply

    system due to instability in the region .

    About 73% of the population lives in

    urban areas concentrated in the northern

    and middle parts of Jordan .

  • CHALLENGES

    Populationgrowth (2.5%/year) and large refugee influxes.

    Rising water needs for

    expanding economic sectors, such as industry and tourism.

    High rate of non-revenue-

    water at around 40%. Limited funding and private

    sector participation.

    Weak coordination with neighboring countries of shared water resources.

    Limited energy sources and high dependency on foreign sources (96% of energy comes from imported oil and gas ).

    Climate change predictions:

    20-25% decrease and strong variability of rainfall; temperature rise of 2ºC

    Long distances between areas

    of high consumption and of abstraction high transportation costs.

  • GROUNDWATER RESOURCES

    Jordan is heavily dependent on groundwater resources (over 50% of supply).

    10 out of the 12 groundwater basins are over-exploited.

    Agriculture is the largest water consumer with 56% of the water use in

    Jordan in 2011.

    AZRAQ BASIN WATER RESOURCES

    Surface Water

    Wadi System with seasonal runoff

    Two main springs; Druze and shishan

    Groundwater

    The Upper Shallow Aquifer

    The Middle Limestone aquifer

    The Deep Sand stone Aquifer

    AZRAQ BASIN DILEMMA

    - Groundwater over exploitation

    - Around 20 m drawdown in the water table level

    Continuous deterioration of water quality.

    Ground water over-abstraction has led to complete cessation of the

    two main springs

    Azraq oasis problem; drought.

    Very high évapotranspiration

    AZRAQ BASIN – AVG. TREND -1.3 M/YR

    AS RESULT OF OVER PUMPING

  • 13

    SUBSTANTIAL INCREASE IN SALINITY IN MOST

    WELLS

  • 17 wells in deep 200m are operated since the 80s.

    Change of quality was detected in water

    withdrawn from AWSA wells.

    Salt water confined at the center of the basin.

    In order to enhance the groundwater management in

    Azraq basin the groundwater resources monitoring is

    highly needed.

    MWI requested KFW to support monitoring project by

    using new technology.

    Installing of egis- imaGeau Equipment's at AWSA

    wellfield in Azraq basin.

    Enhancing sustainable GW management by application

    of real –Time and high temporal monitoring schemes.

  • Monitoring project to evolution of the

    brackish in AWSA wellfield by :

    • Measuring electrical conductivity

    • Measuring Water level

    • Groundwater flow direction

    SALT-WATER INTRUSION

    PROJECTION OF SALT-WATER INTRUSION

  • Immediate ACTION: set up a hydraulic barrier to

    confine the brackish water plume :

    • increase maximum volume extraction from

    southern part of well field (AWSA 12,13,15)

    • Install treatment plant (reverse osmosis) to treat

    the brackish water

    • Mix treated water with groundwater abstracted

    from the Northern part of the wellfield

    • Pipe and discharge the brines to Qa Al’Azraq for

    natural evaporation
