Saudi Arabia
• Aqualia has been working in Saudi Arabia since 2011. In Riyadh, the capital of the kingdom, it developed an important project for five years to optimize the city's water supply network, allowing it to offer a better service to more than 3 million inhabitants.
• Aqualia is also managing the services affected by the capital's metro works (also implemented by the FCC group) and has operated and maintained the Hadda and Arana wastewater treatment plants in the city of Mecca, with half a million inhabitants served.
• At the beginning of 2020, Aqualia acquired from the Saudi group Haji Abdullah Alireza 51% of the company HAAISCO (Haji Abdullah Alireza Integrated Services Ltd), the latter in charge of the operation and maintenance of several desalination plants in Arabia. Among them is the plant at King Abdulaziz International Airport in Jeddah, a concession of the Qatarat company, of which Aqualia also acquired 51% in the same operation. With these acquisitions, an alliance began that in a short time produced significant successes such as the award in 2021 in Jizan (southwest of the Kingdom) of the water supply to one of the main industrial complexes in Saudi Arabia. In the same way, Aqualia operates and maintains, through HAAISCO, two other desalination plants in Saudi Arabia: the reverse osmosis seawater desalination plant at KAUST University, located in Thuwal and which produces 52,250 m3 daily. It also manages the Rabigh MED (multi-effect distillation) desalination plant for Aramco-Sumitomo, with a daily production of 10,000 m3.
• In 2022, The state-owned NWC (National Water Company) awarded a Spanish-Saudi consortium led by Aqualia the water and sanitation management of the so-called North and South Clusters.
These consortiums are already in charge of the Management, Operation and Maintenance of the end-to-end water cycle for seven years in the regions of Assir, Jazan, Baha and Najran, a region known as the South Cluster that covers these four provinces in the south of Saudi Arabia with a population of over five million and a surface area equivalent to half of Spain (240,000 km²). Also, the consortium led by Aqualia (51%), which also includes the Saudi service companies Tawzea (39%) and HAACO (10%), is already managing, operating, and maintening the end-to-end water cycle in the Saudi regions of Qassim, Hail, Al-Jouf and Northern Border in the north of the kingdom.
Between the two contracts awarded to Aqualia, South Cluster and North Cluster, the company is managing water for more than 8 million people.
