13 Cyprus guidelines for domestic treated effluent use for irrigation

14 PLANS AND POLICIES IN CYPRUS The new water policy should include the following specific measures: The new water policy should include the following specific measures: –Secure additional sources of supply –Ensure efficient use of available water –Modify the current irrigation water allocation matrix –Build up strategic water reserves –Maintain and enhance the quality of the water –Introduce new effective/efficient management procedures through the establishment of a Water Entity

15 PLANS AND POLICIES IN JORDAN Support the farmers to improve on-farm water management, especially to deal with water quality issues. Support the farmers to improve on-farm water management, especially to deal with water quality issues. Enhance management of information and make it available to farmers. Regular monitoring and reporting of soil and crop health needs to be introduced Enhance management of information and make it available to farmers.

16 PLANS AND POLICIES IN PALESTINE The highest priority in the Environmental Strategy Plan is given to setting up an effective WW management system. This includes: The highest priority in the Environmental Strategy Plan is given to setting up an effective WW management system. This includes: Maximization of WW collection Maximization of WW collection Upgrading the existing WW collection systems Upgrading the existing WW collection systems Rehabilitation or upgrading of existing WW treatment plants or the construction of new treatment plants Rehabilitation or upgrading of existing WW treatment plants or the construction of new treatment plants Establishment of proper standards for influent and effluent WW quality Establishment of proper standards for influent and effluent WW quality Establishment of a system in which the cost of investment and operation of the WW management systems are recovered. Establishment of a system in which the cost of investment and operation of the WW management systems are recovered.

17 Standards for WW reuse for restricted irrigation

18CONCLUSIONS WW is used alone or mixed with fresh water, mostly on forage and cereals, but also on fruit trees and even vegetables. Concern for human health and the environment are the most important constraints in the WW reuse. WW is used alone or mixed with fresh water, mostly on forage and cereals, but also on fruit trees and even vegetables. Concern for human health and the environment are the most important constraints in the WW reuse. In several cases WW is not properly treated. In several cases WW is not properly treated. Many alternative solutions have been developed with the scientific and technological progress. However, the selection of the appropriate treatment technique, tailored to the needs of each community, means the involvement of specialists.

However, the selection of the appropriate treatment technique, tailored to the needs of each community, means the involvement of specialists. The outflow of the WW treatment systems does not always have a standard quality. The outflow of the WW treatment systems does not always have a standard quality. A serious problem that can create significant obstacles in the safe reuse of the treated WW in agriculture is the lack of information to all the involved actors.

19 CONCLUSIONS The first step towards the improvement of lack of water is the recognition that water is a limited resource. The governments must plan and promote projects that involve non-conventional water resources. There is certain concern among population about safety and quality of treated water. To achieve public acceptance, it is necessary to inform and educate them about the goodness and advantage of using reclaim water.

The transfer of knowledge, experience and know-how in the Med countries will be mostly valuable. More work has to be carried out. Effective technologies and safe practices must be promoted and education and awareness campaigns must be launched.
