During 1983 – 40 years ago – the RWTS (Lines A & B) went into operation. It is the world’s first closed high-pressure water pipeline system, designed to transport 830,000 m³ of water from Al Jubayl on the Arabian Gulf over 467 km to Riyadh.

It was very courageous of ILF, a very young company at the time, to apply this innovative concept without carrying out any pilot tests. A recap of the key data: Double pipeline with a diameter of 60” (1524 mm), total head of the system: 2340 m, 6 pumping stations with an installed capacity of 430 MW.

Under the management of ILF, the RWTS was constructed on budget in just under 3 years. The technical concept has proven itself from the very beginning, with the RWTS still pumping water to Riyadh today.

ILF has made history in pipeline engineering with this project.

To this day, the RWTS serves as a technical model for many successor projects, especially in the Kingdom of Saudi Arabia.

But it is also a model for a decades-long client relationship based on trust and for excellent cooperation between the ILF companies involved, especially from Austria, Germany and Saudi Arabia.
