Internal renewable water resources are estimated at 92BCM, with another 13CM coming in from transboundary resources. Surface run-off represents a total of 97.3km3/year, of which 5.4 km3/year come from draining the aquifers.

Per capita water availability in Palestine will keep decreasing if no new water resources are developed. Since its creation in 1995, the PWA has dealt with water supplies by negotiating for a fair share of water resources with Israel. Unfortunately, the results of these efforts have not lead to any further increase in the Palestinian share from the Mountain Aquifer and the Jordan River in the West Bank or the Coastal Aquifer in Gaza. In fact, the situation has worsened over the years.

Deterioration of water quality in Palestine, especially in Gaza, is a key environmental challenge that requires urgent action. Groundwater resources are suffering due to infiltration of untreated wastewater from leakages in the infrastructure

Gaza’s water crisis has been steadily worsening over recent decades. The area’s only source of fresh water is the Coastal Aquifer, a groundwater basin that runs the length of the Gaza Strip and along part of the Israeli coast.
