lists this plant as the Shuqaiq RO1 replacement, on production since 2023 at 400,000 m3/day with retirement in 2058 and no Sharakat tendering footnote, and lists a SEPARATE Shuqaiq 4 under planning with commercial operation in 2029. The two share a name in common usage and a capacity, but not an owner, a structure or a date. ACCIONA's award release of December 2020 called this plant Shuqaiq SWRO 1; the Shuqaiq 4 label attached to it later. The Saudi Water Authority's own current name for it could not be confirmed, because swcc.gov.sa and swa.gov.sa both sit behind a human-verification wall.
