	abstract = {The water resources of the Island of Cyprus are limited and they are almost fully developed. This effectively means that any further significant water demands from the tourist industry, agriculture and domestic sectors during the next decade will not be able to be met. The Government therefore has developed a policy for further research towards establishing systems and methods for water recycling and conservation. The primary objective of this research project was to study in detail methods of recycling Grey Water from domestic sources (i.e. showers, baths, wash-basins and washing machines) for re-use. Initially the study was directed towards the assessment of actual information and other relevant data on water consumption. Every household and other water consumer is metered in Cyprus. Until this study was undertaken these figures were only used to generate revenue; no analysis was made. The current work has clearly identified an inverse scale effect between number of inhabitants in each property and water used. This phenomenon has been attributed to a relationship between personal water use and common water use. The first remains reasonably constant, the second reduces rapidly with increase in household size. The information obtained from this study of the water consumption characteristics enabled the design and construction of a laboratory based model treatment plant. This demonstrated that grey water can be recycled economically with a relatively simple system of operation to produce high quality water for irrigation purposes. The knowledge and scientific information obtained from this experimental work was applied in the design and construction of a full size prototype treatment plant. This was installed in a normal domestic situation and its use studied over a period of seven months. The data obtained from the installation and use of the prototype plant demonstrated that the system can be applied commercially with similar acceptable results to those obtained in the laboratory. One of the unique features of the Grey Water Treatment Plant is the use of polyurethane foam as a filtration medium. For this reason the project was extended to enable a further detailed in depth study of the filtration process. The results indicated that the efficiency of the foam filter compares favourably with that of the granular filters. The study also demonstrated that the foam filter is more practical, efficient and economical in use. The practicability and commercial viability of the grey water treatment plant has been considered by two United Kingdom based firms, who are currently negotiating for the commercial exploitation of the project. The use and commercial viability of the prototype have also been considered by the Ministry of Agriculture and Natural Resources of the Government of Cyprus who has submitted at the invitation of the Commission of the European Communities an application for funding towards further development.},
