Institutional framework Since several years the water agencies of Jordan are under reorganization to increase effectiveness and responsiveness (Water Utility Policy, July 1997). The Ministry of Water and Irrigation (MOWI) is the responsible body in Jordan for the water sector. It is empowered by the By-Law No. 54 of 1992. Main functions (related to the water sector) of the Ministry comprise the following: 1. Formulation of policy framework and strategy 2. National water planning 3. Regulation on activities 4. Planning of water resources development 5. Formulation and implementation of water and wastewater programs 6. Implementation of research and development 7. Preparation of socio-economic and environmental studies 8. Monitoring of activities 9. Development of human resources 10. Data collection required for decision making 11. Establishment of central data bank 12. Establishment of an information system (Geographic Information System) 13. Dissemination of information and implementation of awareness campaigns With the transfer of water resources studies and monitoring functions and staff from the Water Authority of Jordan to the MOWI, water resources planning and management functions are formally consolidated within the Ministry. Two authorities are affiliated with the Ministry of Water and Irrigation, the Water Authority of Jordan and the Jordan Valley Authority. A Secretary General reporting to the Minister heads each authority. Generally, the Water Authority of Jordan (WAJ) created by Law 18/1988 is responsible as a national government agency for the provision of water and wastewater services including the development and management of sewerage systems, treatment plants and reuse of the effluent in all communities and for all facilities, where private sector is not yet involved (compare section 2.3). WAJ is also responsible for water resources management including the protection of the resources. It is intended to separate the bulk water from retail supply and, therefore, the role of WAJ will also change. In future the main responsibilities of WAJ will be the following: 1. Monitoring of private supply and wastewater disposal contracts 2. Monitoring of management contracts (BOT providers) 3. Management of water resources, bulk supplies as well as wastewater disposal of systems, which are not privatized SA3-1 The Study on Water Resources Management in The Hashemite Kingdom of Jordan Final Report/ Supporting Report Part-A “Master Plan” 4. Provision of support to smaller retail distribution units, which are not operated by the private sector According to its statutes, WAJ is an autonomous corporate body with financial and administrative independence. Generally Accepted Accounting Principles (GAAP) will be adopted. A revision of the WAJ law is under preparation to support three major reforms: protection of resources, private sector participation and sewerage connections. The Jordan Valley Authority (JVA) (created by Law 19/1988 as an extension of Law 18/1977) shall develop water resources, improve environment and living conditions and carry out related works in the Jordan Valley. JVA is responsible for development of water resources for irrigational, municipal, industrial and tourist consumption. It shall plan, design and construct required infrastructure for transport (roads), water supply, sanitation and electric energy supply. It continues to handle a wide range of development responsibilities in the Valley. In addition, future development will focus on such sectors as tourism, industry, manufacturing, advanced technologies and others. The private sector is called upon to assume a proper role in development of the Jordan Valley as well as operation and maintenance activities that are being restructured on a more commercial basis. The Ministry of Agriculture (MOA) is responsible for agricultural irrigation and irrigation water quality. It works in close cooperation with the MOWI on standard settings for treated wastewater reuse. MOA carries out research projects in field of wastewater reuse and its effect on crops. The Royal Society for the Conservation of Nature (RSCN) and the Jordanian Environmental Society (JES) provide training, advisory services and awareness programs in the field of environmental protection and ecology. 2. Water policy The Ministry of Water and Irrigation prepared a Water Strategy for Jordan. It was adopted by a joint session of the Board of Directors of both the Jordan Valley Authority (JVA) and the Water Authority of Jordan (WAJ). The strategy was approved by the Council of Ministers in 1997. Under the strategy, the Ministry and its two authorities formulate a series of policies. 2.1 Irrigation water policy The Policy Paper No. 2 “Irrigation Water Policy” of February 1998 details the long- term objectives outlined in the Water Strategy of Jordan. It states water related issues of resource development: agricultural use, resource management, technology transfer, water quality, efficiency, cost recovery, management and other issues. In the following paragraphs such issues are summarized, which are of particular significance for the reuse of treated wastewater for agricultural irrigation. SA3-2 The Study on Water Resources Management in The Hashemite Kingdom of Jordan Final Report/ Supporting Report Part-A “Master Plan” Under the heading “Resource development and use“ it is outlined that wastewater is a resource and cannot be treated as “waste”. It shall be collected and treated to obtain a water quality that allow its reuse in irrigation unrestricted by health and public health considerations or unduly constrained by high salinity contents. After satisfying the local municipal and industrial needs from unallocated water resources, water resources shall be allocated to agricultural production including livestock. This means that in case of reuse of treated wastewater priority should be given to industrial use in comparison to agricultural use. Advanced methods as drip irrigation, micro-sprinkler irrigation are favored over less efficient methods. Night application of irrigation water, especially in the dry season, shall be encouraged to reduce evaporation losses. Programs shall be prepared to raise the public and farmers’ awareness of the availability of irrigation water, its rational and economic use and on the impacts of its quality. Under the title “Irrigation water quality” it is said, where marginal quality water, such as treated wastewater effluent, is a source of irrigation water, care should be taken, to the maximum extend possible, to have the quality improved to standards that allow it to use for unrestricted irrigation. This can be achieved through blending with fresher water sources. The water price shall at least cover the cost of operation and maintenance, and, subject to some other constraints,
