Water demands in the Aegean Islands have increased steadily over the last decade as a result of a building boom for new homes, hotels, and resorts. The increase in water demand has resulted in the disruption of past sustainable water management practices. At present, most freshwater needs are met through the use of the limited groundwater, desalinated seawater, and freshwater importation. Wastewater reclamation, not used extensively, can serve as an alternative source of water, for a variety of applications now served with desalinated and imported water. Three alternative processes: desalination, importation, and water reclamation are compared with respect to cost, energy requirements and longterm sustainability. Based on the comparisons made, water reclamation and reuse should be components of any long-term water resources management strategy. Ó 2009 Elsevier Ltd. All rights reserved.

1. Introduction The Mediterranean climate near the coasts is characterized by mild winters with relatively low water precipitation, followed by dry summers. The average annual water precipitation at the Aegean Islands is about 585 mm (based on data for Aegean Islands that belong to the Greek Prefectures of Lesvos, Chios, Samos, Cyclades and Dodecanese – see Fig. 1a). Of the precipitation, less than 14 percent percolates into the ground. Evaporation and surface runoff to the sea accounts for 53 and 33 percent, respectively (Hellenic Ministry of Development, 2006). Typical hydrological data for the Aegean Islands are presented in Table 1. More than 50 inhabited islands are included in the aforementioned Prefectures. The total area of the Aegean Islands is 9104 km2, with a combined population of 508,807 people (census 2001) (ESYE, 2002). The Aegean Islands are visited by a large number of tourists during the summer season, with over 15,000,000 overnight stays per year (Dedian et al., 2000). In addition to the tourists, a large number of non-permanent residents, with holiday

homes on the islands, return every summer, or during holiday periods. As a result during August the population of the Aegean Islands is typically 10 times greater than the winter population, whilst in some islands it exceeds 30 times (Dedian et al., 2000). In most of the Aegean Islands, where the freshwater sources are limited, people depended traditionally on rain water collection for most of their needs,...
