Al Khobar 2 desalination plant

Saudi Arabia · Water and environment

In-depth research Release 1

Project scope

Seawater reverse-osmosis desalination (SWRO). The 2023 milestone paragraph reports ramping up production during final testing to a full capacity of 630,000 m³ of potable water per day; another paragraph says daily capacity is more than 630,000 m³ and uses future-tense equipment wording. The source's capacity and status descriptions are therefore inconsistent and do not establish a single unqualified capacity/status.

Reported status and procurement

Reported development

The source says the plant was already supplying the Khobar water network. It reports production ramping up to full capacity during final testing; a quoted ACCIONA director says final testing and commissioning stages were being entered.

Procurement availability
Unknown / not established

Reported procurement

SWCC awarded the construction to ACCIONA and RTCC in 2020.

A source report alone does not establish current progress or an open buying window.

Project summary

Al Khobar 2 is an SWRO desalination plant in eastern Saudi Arabia, and the article says it was already supplying the Khobar water network. The 31 JAN 2023 article reports production ramping up during final testing to 630,000 m³/day, but elsewhere gives a figure of more than 630,000 m³/day and describes equipment in future tense; its capacity and status descriptions are not consistent. The article reports that SWCC awarded construction to ACCIONA and RTCC in 2020.

Evidence limits and unknowns

The source article dated 31 JAN 2023 does not establish the plant's completion or operating status after that date.

The article does not identify the project owner or operator, state project cost or financing, or establish whether any procurement package is currently open.
