The seawater desalination plant at Torrevieja has taken six years to complete at a cost of 215 million euros. Now it is in its test phase where they need to check how well the reverse osmosis membranes are working. Since they were installed in 2010, they have not been used so no one is sure that they will function correctly.
If all goes well then the plant will be capable of producing 80 cubic hectometres of water per year of which 40 will be available for irrigation in the area. As of the moment though, it is unclear how much the price will be for the water produced. Desalination plants consume a lot of electricity and so a new substation is being built to accommodate the demand. Although this is not complete, the testing can still go ahead.
