Free issue post-tensioned concrete pipes, each with a length of 7,5 m, a diameter of 4 m and a weigh of 72 t, are to be transported and erected in the harsh conditions of Sahara Desert.

FACTS

In 1953, the search for the new oilfields in the deserts of southern Libya led to the discovery not only of significant oil reserves, but also vast quantities of fresh water trapped in the underlying strata. The majority of this water was accumulated around 38.000 to 14.000 years ago, though some aquifers are only 7.000 years old. Al Khufra basin, lying in the south east of Libya, near the Egyptian border, covers an area of 350.000 km2, with an aquifer formation over 2.000 m deep.
