Description

Pserimos and Telendos are two islands in Dodecanese with serious water deficit. The groundwater bodies in Pserimos which supply the island are of bad quality and cannot always cover the demand. Also, in Telendos, although water is supplied from the nearby Kalymnos through a connection pipe, very often damages occur to the pipe which results in a lack of water. The project will provide two desalination units, each of 100 m3/per day, which produce drinking water, with all the necessary substructure and installment to the islands of Pserimos and Telendos. The supply of desalination units will improve the quality and quantity of water and therefore will improve the quality of life for the locals and the visitors-tourists in both islands. The project is expected to achieve water quality improved for drinking and irrigation purposes and will also help to the protection of Kalymnos ground waters which according to the River Basin Management Plan of South Aegean are in bad condition.

Summary of project results

Pserimos and Telendos are two islands in Dodecanese with serious water deficit. The groundwater bodies in Pserimos which used to supply the island are of bad quality and cannot cover the demand. Also, in Telendos, although water used to be supplied from the nearby island of Kalymnos through a connection pipe, very often damages to the pipe resulted in lack or poor quality of water. The transfer cost was also high. The current project was necessary in order to ensure the sustainability of fresh potable water production for the islands Pserimos and Telendos. In order to achieve the planned results, two containerized seawater reverse osmosis (RO) desalination units were designed, built, delivered and installed in the two islands producing a minimum of 100m3/ day of fresh potable water each. The produced water is totally safe for human consumption according to the Greek Law and the international standards of potable water (WHO) and it covers the needs of water consumption of the two islands. The two delivered RO desalination units are containerized with all the necessary equipment (seawater transfer piping, brine rejection piping, eletric supply etc) and fully functional. For the minimization of the necessary electricity, an energy recovery unit for energy recovery of over 90%, an inverter at the high pressure pumps, a PV system of 5kW for the unit secondary consumptions, a high pressure pump of high efficiency and RO membranes of low energy consumptions were used.
