Spanish infrastructure major Acciona said its consortium with Saudi partners Tawzea and Tamasuk has been awarded the contract for financing, construction and 25-year operation of three major sewage treatment plants in Saudi Arabia - Madinah-3, Buraydah-2 and Tabuk-2.
These new contracts, worth a combined €855 million ($1.02 billion), have been awarded by the state-owned Saudi Water Partnership Company (SWPC).
These are the first BOOT/EPC (Build, Own, Operate and Transfer/Engineering, Procurement and Construction) contracts that Acciona has signed in the area of wastewater treatment in the Middle East.
The Madinah-3 wastewater treatment plant (WWTP) will be located in the fourth most populated city in Saudi Arabia with more than 1.1 million inhabitants, and will have a capacity of 200,000 cu m/day (expandable to 375,000 cu m/day) to treat urban wastewater.
The Spanish group will also be responsible for the facility’s development, design, financing, construction, operation and maintenance for 25 years.
As per the deal, Acciona will be building 23 km of recycled water collectors for irrigation, three storage tanks and the respective pumping stations.
The Buraydah-2 project, which will boast a 150,000 cu m/day capacity and Tabuk-2, with a 90,000 cu m/day, are located in rural areas in the central and northern regions of the country, respectively, and will serve one million inhabitants.
Acciona said as per the agreement with SWPC, it will develop, design, finance, construct and operate these two facilities for 25 years and will also build 34 km of recycled water collectors for Buraydah-2 and another 28 km of collectors for Tabuk-2.
The three plants will each have a collection well and pumping station, pretreatment installation, biological reactor, sludge line, and recycled water pumping station, it added.
With these new contracts, the Spanish infrastruture group has boosted its position as a key company in Saudi Arabia’s water sector, where the group has developed important desalination projects.
Last year, Acciona had clinched the contract for the construction of the Al Khobar 2 desalination plant, on the east coast of Saudi Arabia, 400 km from capital Riyadh.
In the same area, the group also completed the commissioning of the 210,000 cu m/day Al Khobar 1 desalination plant last year, which can currently serve a population of 350,000 inhabitants.
