Contractors working for Saudi Arabia’s National Water Company (NWC) have completed the initial works on the first phase of the Riyadh strategic water storage project.

The initial phase will store up to 600,000 cubic metres of water and is projected to reach completion by the summer of 2015.

The remaining first-phase contracts, worth a total of SR1.6bn ($427m) and which will provide a further 4 million cubic metres of storage, have been finalised. Work has begun in four locations and should be completed in 2016.

The project, which comprises multiple locations across the city, aims to secure Riyadh’s water supply and provide continuous supply in the event of maintenance or network failure. The second phase will bring the total storage capacity to 6 million cubic metres and will also include the construction of transmission lines.

NWC is carrying out similar schemes in Jeddah and Mecca to build storage facilities for up to 6 million cubic metres of water.
