The historical archaeological marvel in southern Syria
The Dicablos water tunnel in the Horan plain, linking the Levant to Jordan, and the longest in the world. ... took 80 years to complete ...
.................................................
The Dael-Umm Qais tunnel is the longest water tunnel in the world.
The Dael - Umm Qais tunnel is considered an underground water miracle built by the Romans to connect the cities of the Decaplus with each other, and the tunnel extends 170 km between Jordan and the Levant and is 9 times longer than the second longest tunnel in the world, located in Italy, and is considered an underground water empire.
The tunnel is described as a "heritage marvel" indicative of the ancient civilizations that inhabited Houran, as the tunnel connects a group of villages in a unique water system fed by a group of abundant springs in Houran.

Decapolis Tunnel ... the longest tunnel in the world
.
Its length exceeds 170 km ...
At the outset of the topic, there are many who do not know about this tunnel. It is an extension between several cities out of the ten Roman cities. It begins in two stages:
- The first stage :
The main one is from Dael in the western countryside of Daraa, passing through Daraa, Balatrah, Kfarsum, Samar, and Abder and its valleys to Umm Qais in Jordan
- The second phase:
The branches from the main one are called the sub-branch. It starts from al-Mughayyir at Ain al-Muallaqa and also branched out with eyes and valleys. The function of the branches is to bring in more quantities of springs and rain to feed the cities and the baseline ten cities, especially in wars ....
.
how did that happen ?
- The Romans began building the tunnel in the second century AD during the reign of Emperor Hadrian in 130 AD, and work on it continued for more than eighty years, incessantly.
It starts in the Levant from Syria now, passing through the Horan Plain from the city of Dael, and its beginning will be in the shape of (U in English, U) in order to collect rain and springs near it in order to supply the tunnel through Daraa and enter the Jordanian lands from the village of Al-Tarah towards the Wadi Al Mughayer.
Of course, here it is provided with nearly ten strong springs until now, branches begin in the village of Al Mughayer towards (Marw, Al-Al and Hakama), their valleys and the springs of these villages, and then the main tunnel
To exiting and the exiting branch also branches in more than several branches in the middle of Kharga and the valley of Porcupine and Arqoub towards Khuraiba to the main spring and then diverges to Ain Qweilbeh and heads to Ybla here. Notice that there are rooms in which the workers used to sleep, and there is also a place to put lighting and lamps every two meters on the sides of the tunnel And every one kilometer the angle of inclination is determined in order to draw the water, and also there are writings in the Romanian and Arabic languages found on the wall of the tunnel, with a plaster so that the tunnel water does not leak through the cracks, and also in some areas there is a staircase in order to withdraw water ...
From Ybla to Ain Terab, through Kfarsum, and then to Samar, to Abder, to Umm Qais
Of course, here there were two main tunnels, one under and another above, between Samar, Abder and Umm Qais, meaning a tunnel with two floors.
The most destroyed areas of the tunnels are the ones in Kharga and Yebla due to earthquakes and natural factors that resulted from the strength of the water entering the tunnel, and it is in need of care and rehabilitation.
