Significant increases in water tariffs have taken place or are planned in all sectors, and lower prices for effluent and brackish water encourage their use for irrigation. A quota of potable water is allocated to the agricultural sector each year, farmers who opt to exchange part of this quota for alternative sources can secure the volume of wastewater they will procure at a fixed price. The use of such data by the OECD is without prejudice to the status of the Golan Heights, East Jerusalem and Israeli settlements in the West Bank under the terms of international law.
