Hadrian's reservoir is located at the western foot of Mount Lycabettus, and its pipes covered the water needs of the area's residents for over 1,000 years. The tank was abandoned during the Ottoman rule, causing most residents to become reliant on wells. Restoration works began in 1847, though it stopped to be Athens' primary water source in 1929 when the Marathon Dam was constructed.
The volume of the reservoir is aproximatelly 500 qm. The reservoir is located in Dexameni (Reservoir) Square in Kolonaki, right below the homonymous cinema which is built on a concrete slab placed above the the domes of the reservoir and it is not part of the water supply system of Athens.
The study was based on the EC2 and on Karantoni et al failure criterion.
