Saudi Arabia issues tenders for two major water pipelines

4 September 2025

 

Saudi Arabia’s Water Transmission Company (WTCO) has opened bidding for the construction of the Jubail-Buraidah water transmission system.

The greenfield project comprises approximately 348 kilometres of pipeline. It will have a transmission capacity of 840,650 cubic metres a day (cm/d) and will supply water from the Ashmasiah reservoirs to cities and towns across Al-Qassim Province.

WTCO has also issued a second tender for the construction of the Ras Mohaisen-Baha Mecca water transmission system. The greenfield project will involve approximately 325km of pipeline.

It will have a transmission capacity of 542,000 cm/d. The system will deliver water from Ras Mohaisen to the Adham and Aradhiyah regions.

Engineering, procurement and construction (EPC) contractors are invited to submit technical and financial bids. The bidding deadline for both projects is 2 December 2025.

The Jubail-Buraidah project, scheduled to begin construction in 2027, is large by WTCO standards. The company’s second phase of the Khobar-Hofuf system, completed in 2024, was 140km in length, with a capacity exceeding 530,000 cm/d.

Saudi Arabia also has even larger independent water transmission pipeline (IWTP) initiatives under way. One such project, also linking Jubail and Buraidah, spans 587km and carries 650,000 cm/d.

In June, the local Mutlaq Al-Ghowairi Contracting Company (MGC) secured the EPC contract for this project.

It will have a total cost of SR8.5bn ($2.2bn).
