The Palestinian Water Authority (PWA) has adopted several key elements as a water policy to be used as a basis for all decisions within the water and wastewater sectors. In addition, a water management strategy has been developed which includes the key strategy of “promoting regional and international cooperation”. The Palestinian National Authority is a Core Party Member of the Multilateral Working Group on Water Resources within the Peace Process agenda. Under this framework, the PWA is participating in several projects that not only have a national focus, but also a regional focus in order to promote a factual basis for regional cooperation in the water sector. This presentation will outline the ongoing projects in the multilateral framework pointing out the regional significance for each project and emphasizing the importance of building strong professional and technical liaisons in the water sector.
