GazaWaterFacts�  Gaza’s water and sanitation crisis will worsen, while

population is expected to reach 2.1 million in 2020, in conjunction with projected water demand to grow to 260 MCM/y in 2020 for different uses.

�  Current installed power supply to operate water and wastewater facilities is estimated by 29 MW, meanwhile, projected power supply demand for water and wastewater facilities is estimated by 81.5 MW in 2020. Blackouts of

12-16 hours/day are restricting the provision of basic services.

anthropogenic replenishments. �  The natural replenishments of the aquifer : 35-45 mcm/yr, �  The anthropogenic replenishment (agricultural return flow and

wastewater) : 25-35 mcm/yr, �  The lateral inflow from the eastern part of the aquifer is about 10-20

yr. �  Water wells: 12500 (2500 registered and 10000 illegal)

� The Palestinian National Authority, particularly the

Palestinian Water Authority should take concrete steps to publically reaffirm Palestinian water rights as an essential and fundamental step to realizing the Palestinian right to self-determination and the Palestinian state.

� The international donor community must exert political efforts to resolve the underlying water injustice in the occupied Palestinian territory based on the principle of territorial integrity rather than funding costly projects temporarily alleviating a humanitarian crisis.
