After 35 months of construction, JÄGER BAU is delighted to announce the successful breakthrough of the 3,430-m-long water supply tunnel on Crete. The 250-m-long, 600-tonne double-shield tunnel boring machine reached the light of day once again on 28.11.2017.


Schruns-based Jäger Bau GmbH was commissioned in the context of a service contract with the construction of the 3,430-m tunnel drive, complete with full tubbing lining, using a 5-metre double-shield tunnelling machine.


Jäger Bau supplied the entire tunnel excavation unit, key personnel and technical expertise for this project.


The first day of March 2015 marked the start of the adventurous “journey” through the mountainous landscape of the island of Crete, legendary birthplace of the god Zeus.

After the successful execution of this complex and occasionally difficult construction order, the staff of JÄGER, the Greek partner company Intrakat, and representatives of the client and the Greek Ministry of Infrastructures celebrated the breakthrough of this major tunnel for drinking water supply on Wednesday last.

As early as this coming winter, excess rainwater will be diverted from the Lasithi plateau, well-known to many holidaymakers on Crete, via the 3,430-m-long tunnel with its 15% gradient to the Aposelemis Dam below.
