      Background
       •   Limited water availability
       •   Increasing demands on water resources for (household, 
           commercial, industrial, and agricultural purposes) due to 
           population and economic growth 
       •   Poor water policies and management frameworks
       •   Contamination of ground and surface water by industrial effluents, 
           and agricultural chemicals 
       •   Over abstraction of conventional water resources 
       •   Therefore  Need for non-conventional water resources
  Benefits of Reuse in Agriculture
  Reduction of surface water pollution
  Maintain water security
  Savings “high-quality” fresh water 
  Providing alternative water resources 
    Reallocation of water budget
  Nutrients in treated wastewater can 
   reduce the need for applying 
   chemical fertilizers
    Water Reuse Situation
                                       9 3
    Arab countries currently produce around 10.8 x10  m /year of 
    wastewater, of which:
       55% reused in agriculture, landscape irrigation 
       15% treated in industrial cooling and environmental protection.
       In some countries, reclaimed wastewater is used for groundwater 
       recharge to protect freshwater resources
       Agriculture is considered to be the top consumer of water 
       resources, with a share of about 85% of available water resources 
       in Arab countries.
    Water Reuse Situation
                                  and Ground water recharge
    Standards exist in most countries – focus on effluent quality and not irrigation water quality – 
    most WWTP do not meet the set requirements
    Safety control and risk management system is only available in Jordan (Crop Monitoring System)
