The quantities of extraction, which exceeded 170o/o of the safe yield of extraction
from the basin as illustrated in the table (2), includes the amount of water
abstracted for drinking, which is estimated to be more than 80 million cubic meters,
and considered to equal almost 100% of the safe yield. While the amount of water
utilized for agriculture, which is more than 60 million cubic meters is equivalent to
70% of the safe yield of the basin, and a very small percentage of extraction is
being used for industry (Figure 5).

Current Sfaúus
This basin is located in the eastern desert , (90) kilometers away from theeast of Amman, with an estimated area of about (12 4OO) km 2 in Jordan, andan average precipitation of (3000) mm / year. Shallow water layers aresurrounded by Basalt which is above the marble, and is composed of graniteand limestone, are the most important aquifers. And there is a deep confinedwater layer composed of limestone and granite which is considered theformative layers of Amman - Wadi Seer. This basin extends into Syria, wherethe subsurface water flowing from Syrian territory to Jordanian water levels isabout (18) million cubic meters annually.
Hi stori cal devel o pm ent
The quantity of safe extraction is about (24) million cubic meters of water
from the water layers, noting that extraction have exceeded the safe yield
to about 250% for the past five years, as shown in Table (6) and Figure
(7). The decrease in water level reached about (15 m) during the previous
twenty years with the increase in salinity level from 270 to more than 500
ppm.
Figure (8) gives an example on the decrease of water level in one of the basin
wells ( Azraq well- 12), while figure (9) gives an example on salinity level
increase in one of the basin wells (owsa well -10)

Due to the presence of salt water in the basin, the extraction which
exceeds the safe yield of the basin will rush to movement of salty water
into the whereabouts of fresh water (such as drinking water field wells),
which causes the negative change on the quality of water as well as on
economic projects and investments in the basin, especially agricultural
ones.
Consumption of groundwater in various secfors (drinking,industry and agriculture)
Quantities of extraction, which exceeded 250% of the water safe yield of thebasin, as shown in Table (7), includes the amount of water extracted foragriculture, as estimated to be more than 33 million cubic meters, and is equalto almost 136% of the safe yield. while the amount of water extracted fordrinking is more than 22 million cubic meters, and equals to 96% of the safeyield. Only 8o/o of the safe yield is being used in industry (Figure (10)).

How the exploited groundwater is distributed for alluses andfor d ifferent governorates
The following table shows the amounts of groundwater allocated to thevarious governorates from AlAzraq basin. Zarqa Governorate occupies thehighest percentage of total water extracted from the basin, where water ismostly used for agriculture and drinking.

over-extraction of the basins.2. Water available during the off-peak season (winter) calculated to be 17o/o
added to the per capita share (80-1201/capita/day) during the peak period(summer time) according to the calculation model of the re-allocation plan.Based on the previous model, an assumed growth rate of industry (see Table
(11)), reflects the increase in demand in the industrial sector.
3. Additional quantities of water from the basins will be used for drinking,rather than agriculture, under the substitution mechanism which uses treatedwater resulting from sewage plants for agriculture. Accordingly, this planincludes an annual reduction in groundwater extraction procedures to reducethe amount of water abstracted for agricultural purposes from eachgovernorate. (see appendix 2,3)
Finally this plan assumes a constant amount of water coming to the capitalAmman from Zay and Zara-ma'en.
2.3 Reduction súages and procedures
This action plan consists of three phases: short, medium and long term. Eachphase is summarized as follows: (see annex 1)
1. Short{erm phase: The phase will start from the onset of implementationand end at the beginning of 2014. lt aims at detecting any additional violationson the extraction of the basins, and collecting information needed for thesecond phase, including the following actions:
o Starting a socio-economic survey for the investments that exploitgroundwater in the basins.
o Design suitable procedures for improving the groundwater monitoringsystem to ensure complete cessation of water depletion of the basins andsecuring formal approval of those procedures with the corporation of relatedparties, like the ministry of internal issues. (Which include the activation ofpunishment law clauses and similar illegations.)

o Working along with the Ministry of Municipalities to take water issues intoconsideration when planning lands usages.
2. Medium-term phase: This phase aims to effectively reduce the over-extraction of water from the basins, and to find alternative sources to theamount that will be reduced aiming to reach safe yield. This phase will extendfrom 2014 to 2020 and will incorporate the following actions:
o Closing all illegal, non-working wells by the year 2020 according to thefollowing
See annex (4) that shows 32 wells for Amman -Zarqa Basin and annex (5)that shows 736 wells tor Azraq Basin.
Actually starting in the reduction of the over- extraction of basins for eachgovernorate, taking into account the volume of demand in each governorate,water quality and uses, and volumes being pumped) see annex 2 for thereduction plan of Amman-Zarqa Basin, and annex 3 for the plan of AzraqBasin), after ensuring new water sources alternatives to compensate for theover-extraction.The enforcement of new groundwater monitoring law.The leasing and procurement of some agricultural wells (taking into accountthe degree of salinity in these wells) and the exploitation of their waters fordrinking purposesEnsuring that all illegal, working wells are operating in accordance with thenew groundwater monitoring law.Reviewing the amount of water that will be extracted every five years for theadjusted wells.Starting the reduction of over- extraction of basins for each governorate,taking into account volume of demand, water quality and uses, and volumesbeing pumped, starting with governmental drinking water after consideringother water sources alternatives.Working with the Ministry of Finance and the Department of land and surveyto solve the problem of some land in Azraq.Begin the utilization of other sources of water for agricultural uses other thangroundwater (treated wastewater, water harvesting,).Activating the work with the Ministry of Municipalities for the applicationof water considerations in the planning of land use
3. Long-term phase: This phase aims to continue with the activities ofmedium{erm phase, those that maintain an amount of extraction from basinsequals to the safe yield, or to find new solutions to achieve the safe yieldlevels of the basins. This phase begins atter 2020.This phase will contain a

The over-extraction can be also reduced from the basin to a sufficient extentto reach the safe yield of 24 mm 3, where the reducing percentage in the over-extraction of the basin ranges from 37o/o in 2014 to nearly 100% in 2020. Thisratio has reduced the value of the current over-extraction of 27 .7 Mm3 to 17.5Mm 3 in 2014 and nearly 0 Mm 3 in 2020, which is equivalent to an average of13.4 Mm 3 between 2014 and 2020,Annex 3).
Results also indicate that by using the excess water from the off-peak periods,by using part of the water in excess from demand after the arrival of Disiwater, and by reducing the amount of water utilized for agriculture, whichconsidered to be the most water consuming sector in this basin, it will bepossible to reduce the percentage of over-extraction of the basin byapproximately 100% by the year 2020 to reach the safe yield.
Long-term phase results:
By comparing the results of the medium term phase with those of the plan'sobjectives, it becomes apparent that despite serious efforts to reduce overextraction of water from underground basins, Jordan is still in need of other projectsto support its efforts. This becomes even clearer when the growing needs of varioussectors (drinking, industry, tourism and agriculture) are taken into consideration.The Red-Dead canal project offers a viable solution and represents a way fonruardto meet demand and preserve Jordan's underground basins for future generations.
