Project scope
Phase 1 of the Hassyan Sea Water Desalination Project: 180 million imperial gallons per day (MIGD) capacity using seawater reverse osmosis (SWRO), with seawater intake and outfall systems, electrical facilities, and potable water storage.
Reported status and procurement
- Reported development
DEWA signed a 30-year water purchase agreement with ACWA Power; key facts list a 30-year BOO offtake contract.
- Procurement availability
- Unknown / not established
A source report alone does not establish current progress or an open buying window.
Project summary
Hassyan IWP is Phase 1 of the Hassyan Sea Water Desalination Project in Dubai, next to the Hassyan Energy power plant. ACWA Power describes a 180 MIGD seawater reverse osmosis (SWRO) facility, including seawater intake and outfall systems, electrical facilities and potable water storage. (ACWA Power, project description; page observed 17 October 2026.)
ACWA Power reports a 30-year water purchase agreement with DEWA and lists a 30-year BOO offtake contract. It reports project cost of US$936 million and gives 15 February 2027 as the planned commercial operations date; that date is a plan, not confirmation of achieved operations. (ACWA Power, project description and key facts; page observed 17 October 2026.)
DEWA’s Q1 2026 report identifies Block A of the Hassyan SWRO plant and reports that it had been commissioned by Q1 2026, adding 60 MIGD to water capacity. This block-level addition does not change the project’s stated 180 MIGD Phase 1 scope. DEWA also expected to add a further 120 MIGD of SWRO capacity in 2026, but the report does not clearly establish that all of this expected capacity belongs to Hassyan. (DEWA, Q1 2026 report, p. 2; capture observed 5 November 2026.)
Reading-scope note: This summary uses ACWA Power’s project page and page 2 of DEWA’s four-page report. The other report pages and graphical content were not interpreted; no OCR was used. The DEWA capture date is an observation date, not a stated publication date.
Evidence limits and unknowns
ACWA Power lists 15 February 2027 as the planned commercial operations date, but the reviewed material does not confirm whether that date was achieved or establish whole-plant acceptance. (ACWA Power, key facts; page observed 17 October 2026; DEWA, Q1 2026 report, p. 2.)
DEWA’s report does not clearly attribute all of the additional 120 MIGD expected in 2026 to Hassyan, and the reviewed page does not establish whether that expected capacity was subsequently added. (DEWA, Q1 2026 report, p. 2; capture observed 5 November 2026.)
The reviewed material does not establish sustained plant output, current construction status, or an available procurement package or buying window. (ACWA Power, project page; DEWA, Q1 2026 report, p. 2.)
