In most of the countries of the Mediterranean region, wastewater is widely reused at different extents within planned or unplanned systems. However, only few Mediterranean countries (such as Cyprus, Jordan, and Tunisia) have included water reuse in their water resources planning and have official policies calling for water reuse. Regarding the EM-Water countries, legal standards for wastewater reuse have only been adopted in Jordan and Turkey. The Palestinian Water Authority has developed guidelines for wastewater reuse, but these have not yet been enforced. In Lebanon, no specific guidelines for the reuse of wastewater have yet been developed, but are envisaged for the future. This delay can be explained by the fact that Lebanon is not as much suffering from water shortage as are other MEDA countries.
