Not only have water reservoirs, pumps, treatment facilities and distribution networks been affected by military conflicts and occupation by foreign forces, but also have wastewater treatment facilities and irrigation networks been destroyed during military incursions. Operation and maintenance of water facilities is also limited during periods of insecurity and occupation, which have affected the availability of fuel for pumping water (e.g. in Yemen), the import of replacement parts (e.g. in Palestine), or access of employees to operate water facilities (e.g. in Iraq). In preparation, some officials have already considered relocating the capital to the coast.
