Severe freshwater scarcity remains a crippling livelihood and economic constraint across southern Iraq. Basrah Governorate has faced decades of unstable potable water supply, driven by shrinking river runoff, accelerating desertification and rapid urban population expansion. Large-scale seawater desalination sits at the core of Iraq’s national water security strategy to mitigate chronic water shortages, yet purpose-built long-distance transmission pipelines to deliver desalinated water to end communities have long remained a critical infrastructure gap.
Against this backdrop, PowerChina issued an official corporate announcement on July 22 covering a landmark subcontract signing. Sinohydro 5B (China Water Resources and Hydropower Fifth Engineering Bureau), a fully owned subsidiary of PowerChina, signed a Design & Build water transmission subcontract with Iraq’s Al-Ridha Group. The contract covers a complete long-distance freshwater transmission network serving the region’s flagship seawater desalination complex. This USD 12.4 billion contract reinforces Chinese contractors’ leading competitive edge in full-spectrum supporting infrastructure for Middle Eastern desalination assets under the Belt and Road Initiative.
1. Official Contract Announcement & Financial Scale
On July 22, PowerChina released a formal stock exchange filing confirming a legally binding subcontract with Iraqi local developer Al-Ridha Group. The scope exclusively covers the dedicated water transmission backbone for the Grand Basrah Seawater Desalination mega-project.
- Total contract value: Approximately CNY 89.25 billion, equivalent to USD 12.4 billion
- Contract positioning: This is a core auxiliary subcontract to the overarching Basrah desalination plant EPC scheme. Sinohydro 5B will deliver the full transmission pipeline network that links the desalination facility to residential and municipal water demand nodes across Basrah Governorate.
2. Project Location & Full Construction Scope
The entire transmission network spans Basrah Governorate in southern Iraq, acting as the critical distribution backbone for the world-class desalination facility rated at 1,000,000 m³/day freshwater output. The full Design & Build scope comprises a closed-loop potable water delivery system with three core assets:
- A 240-kilometer high-capacity trunk transmission pipeline for bulk cross-regional transportation of desalinated water
- One central main pumping station to supply primary hydraulic pressure for long-distance water conveyance
- Nine distributed receiving pumping stations deployed across Basrah’s urban and suburban zones to regulate regional water pressure and consistent supply stability
This integrated pipeline and pumping station cluster resolves the critical bottleneck separating desalinated water production and end-user distribution. Once fully commissioned, the network will deliver reliable potable water to millions of local residents across southern Iraq.
3. Staged Project Timeline & Defect Liability Commitment
The contract adopts a segmented delivery schedule tailored to large cross-regional Iraqi municipal infrastructure projects, paired with a standard long-term defect liability period aligned with international FIDIC engineering norms:
- Limited Notice to Proceed (NTP) Mobilization Phase: 6 months, covering site clearance, geotechnical site investigation, detailed engineering design, global equipment procurement planning and temporary construction camp establishment
- Main Construction & Implementation Phase: 1,350 calendar days, including pipeline installation, pumping station civil works, mechanical & electrical fitting, full-system hydrostatic pressure testing and integrated commissioning
- Defect Liability Period: 24 months post-substantial completion. During this window, Sinohydro 5B will deliver routine equipment inspections, pipeline maintenance, operational fault troubleshooting and dedicated technical after-sales support to guarantee sustained stable operation of the entire transmission network.
This multi-phase delivery framework reflects PowerChina’s mature governance system for large overseas infrastructure projects, balancing pre-construction mobilization, large-scale civil execution and long-term asset performance warranty.
4. Strategic Industry & Market Significance
This USD 12.4 billion Basrah water transmission subcontract carries multi-layered strategic weight for global water infrastructure stakeholders, Chinese international engineering firms and Iraq’s national water security agenda:
- Expands Chinese contractors’ full-spectrum desalination support capacity: Most international competitors focus solely on constructing desalination plant core process facilities. PowerChina specializes in complementary long-distance transmission infrastructure, delivering end-to-end desalination + pipeline distribution solutions that create differentiated bidding advantages across Middle Eastern tender competitions.
- Addresses Iraq’s critical livelihood infrastructure deficit: The Grand Basrah Seawater Desalination Plant ranks as Iraq’s largest single desalination asset. The 240km transmission pipeline network will resolve generations-long drinking water shortages for Basrah’s urban and rural populations, marking a landmark livelihood cooperation project under China-Iraq bilateral ties.
- Establishes replicable benchmarks for Chinese water engineering in the Gulf Cooperation Council (GCC): PowerChina has a proven track record delivering seawater desalination and transmission schemes across the UAE and Saudi Arabia. The Sinohydro 5B subcontract will serve as a replicable reference for future large-scale water conveyance tender bids across the wider Middle East.
- Accelerates exports of China’s complete water industrial supply chain: The project will drive overseas shipments of domestic large-diameter pipeline materials, high-efficiency water pumps, intelligent water distribution control systems and heavy construction machinery, unlocking incremental export value for China’s downstream water manufacturing sectors.
For global EPC contractors, Middle Eastern municipal water authorities, cross-border water investment institutions and desalination technology vendors, this project demonstrates that integrated pipeline and pumping station delivery capacity has become an indispensable competitive advantage to secure mega regional desalination tenders.
