Water resources management for the prefecture of Dodekanisa of Greece Original Research Article

In this work a detailed feasibility study for the islands of the prefecture of Dodekanisa in Greece is presented. The aim of this study is the management of the water resources of these islands taking into account the limited water resources of the area and the limited financial support of the local authorities. The results of the study are presented in different scenarios depending on the level of financial support of the local authorities or the available subsidies offered by the European Union. One scenario for the 100% finance, by private construction companies, is also presented for BOOT contract. The aim of this study is twofold. First to produce and meet the demand for potable water for fourteen remote and arid islands and second to treat the municipal wastewater of the local communities in these islands, with conventional and novel methods for the production of water for irrigation. The operation of the complex of these desalination and wastewater treatment plants should be optimized so that a reasonable price of the produced and treated water could be achieved. The introduction of new technologies, automation, data acquisition and remote operation can be used to reduce the labor and maintenance cost for these small size desalination plants. The construction and operation of these facilities are combined with a wind power plant, so that the energy consumption and consequently the energy cost is minimized. The project includes the management scheme and the operation procedure for a particular period of time. It is a complete and detailed feasibility study giving all the technical and economical evidence for a viable investment of the private sector.
