Ras Al Khair-Riyadh Water Transmission Line Project is the first stage of a project to provide Riyadh with water and one of the biggest water supply schemes in the Gulf and Middle Eastern regions. The Project aims at meeting long term water requirements of Riyadh and upon its completion, 900.000 m³ of water can daily be carried to Riyadh from Ras Al Khair Sea Water Treatment Plant via a 72 inch 2x267,5 km steel pipeline.

The scope of the Project includes pipe coating, installation, line valve stations and other engineering structures as well as access roads, pipeline tests and start up of the system.

Civil works are already over under the Project which continues under the commitment of the Joint Venture of Limak and Mapa. Following hydrostatic tests, the system will be started up and the transmission line delivered to the employer. The Project is scheduled for completion in 2014.
