Engineering, procurement and construction (EPC) contractors are preparing to bid for a contract to develop a major water transmission system (WTS) connecting Ras al-Khair to Riyadh in Saudi Arabia. The client, Saudi Arabia’s Saline Water Conversion Company (SWCC), expects to receive bids for the contract by the third week of July. The second phase of the Ras al-Khair to Riyadh WTS project is expected to extend 391 kilometres and can transmit 1.2 million cubic metres a day (cm/d) of water. WTTCO is planning $6.7bn of new water transmission programme as part of plans to improve potable water delivery to meet future demand. The recently formed utility has tendered three major projects, estimated to total $3.4bn, covering installing more than 1,200 kilometres of wide-diameter transmission pipe from desalination complexes on the coast to interior towns and cities. The first of the three schemes is the Al-Duwadimi to Afif water transmission system comprising a 450km-long pipeline, with a pumping capacity of 226,000 cubic metres a day (cm/d), from three pumping stations and a total storage capacity of 600,000 cubic metres. The second project is called the Riyadh Ring water transmission systems. It involves the installation in and around Riyadh of 235km of pipes with a pumping capacity of 3 million cm/d, two pumping stations and a total storage capacity of 16 million cubic metres. The third contract involves the construction of the Shuqaiq-Jizan transmission pipeline. The pipes will have a length of 575km and serve Jizan and surrounding areas. It will have six pumping stations with a capacity of 100,000 cm/d each and total storage of 6.2 million cubic metres.  The pipeline projects are the first of nine that WTTCO intends to tender over the next 12 months. In the first half of 2024, it will launch new pipeline schemes from Tabuk to Al-Ula and from Rabigh to Jeddah, as well as the West Riyadh and Southern Riyadh transmission lines. The total estimated investment in the four projects is more than $4bn.   (ICE RIYADH)
