Energy Globe World Award 2019

Finalist in the category Water



Project:
Desalination of Seawater to potable using Wind Power in the Island of Milos
Submitted by:
ITA Group of Companies
Country:
Greece


The Seawater Reverse Osmosis desalination plant with a nominal capacity of 4.500 m3/day is a state-of-the-art seawater reverse osmosis desalination plant. The plant is located at an old bentonite clay mine on the island of Milos. It produces high quality potable water, in accordance with EU legislation.

Initial situation
Until 2007, when the seawater reverse osmosis desalination plant was inaugurated, the island of Milos used poor quality water, brackish and corrosive, coming exclusively from drilling, mixed with expensive water that reached the island. The cost of transporting the water to meet the island‘s needs was around € 12 per cubic meter which equals approximately 5 million € yearly. Now, it is only a fifth of that cost.

Solution
The project led to the complete substitution of drinking water transported in tanker ships or pumped from local wells, which was of very poor quality and scarce availability. The technology used for the project is that of reverse osmosis which requires only the electricity. The combination of the desalination plant with the wind turbine leads to optimal results for the island environment and the inhabitants of Milos, leading the way down the path of sustainable development.

Innovation
This technology involves reverse osmosis seawater desalination as a more environmentally friendly and cost-effective option compared to other water desalination technologies. It is the first CO2-neutral desalination project in Greece that does not burden the electric load of the local power network and the local thermal power production plant. It is also the first desalination plant in Greece located after a special architectural survey, in order to minimize any negative effects to the landscape as far as visual intrusion is concerned.
