Jordan faces a sincere water crisis. Groundwater is the major water resource in
Jordan and most of the ground water systems are already exploited beyond their estimated
safe yield. The Amman Zarqa Basin is one of the most important groundwater systems in
Jordan, which supplies the three largest cities in Jordan with drinking and irrigation water.
Based on new data the groundwater drawdown in the Amman Zarqa Basin is studied. This
basin is the most used drainage area in Jordan. Groundwater drawdown in eight central
representative monitoring wells is outlined. Based on almost continuous data for the last 15
years (2000–2015) an average drawdown for the whole basin in the order of 1.1 m·a−1
is
calculated. This result is in accordance with results of previous studies in other areas in
Jordan and shows that, until now, no sustainable water management is applied.
