The Tenerife Cabildo, under the leadership of the Tenerife Island Water Council, has initiated the expansion of the Adeje-Arona submarine outlet. This outlet serves the purpose of discharging saline waters from the Adeje-Arona regional desalination station (EDAM) into the sea.
The project is set to require an investment of 4.1 million euros, focusing on directing the saline waters from the aforementioned Adeje-Arona station towards the final stretch of the Troya ravine to reach the sea in a controlled manner.
Information from the Tenerife Council indicates that the objective of the project is to enhance the discharge of saline waters into the sea at a greater distance from the coast.
EXPANSION OF 200 METERS
As part of the project, the outlet will be extended by 200 meters, positioning the discharge point at a depth of over 40 meters and allowing the discharge to occur at a distance of 1,100 meters from the coastline.
The enhancement works will entail the implementation of safety measures in the surrounding area of the Troya ravine mouth, including restricted access. The estimated duration of the project is six weeks, subject to sea and wave conditions, as announced by the Insular Water Council.
The Cabildo emphasizes that the upcoming actions are intricate, given their execution at a significant depth exceeding 40 meters, entailing the deactivation of the current underwater outlet in order to prolong it.
IMPROVED DRAINAGE SYSTEM
The project will significantly enhance the discharge of saline waters from the regional desalination facility once the purification treatment is completed, allowing for the water to be regenerated for agricultural purposes. Consequently, due to the deactivation of the existing outlet during project development, the treated water and salt from the regional facility will be discharged at the end of the Troya ravine.
The enhancement project for the Adeje-Arona submarine outlet also includes linking the two pipelines—the existing and the new one—requiring the construction of a connecting section to enable the discharge of saline waters over one kilometer away from the coast, as detailed by the Tenerife Island Water Council.
