Hassyan IWP seawater intake and outfall programme

Aerial view of the Hassyan IWP coastal site, seawater frontage, breakwaters, and intake-outfall infrastructure corridor

ACWA Power

Hassyan's first 60 MIGD block is operating and the remaining 120 MIGD is moving through the 2026 delivery window. The confirmed marine scope covers seawater intake and outfall pipelines, diffuser integration beside the adjacent power plant, and capacity provision for a planned additional 60 MIGD.

Project signal

Commissioning in UAE

The intake and outfall works remain part of the existing EPC programme. Acceptance, operating performance and expansion timing are the outstanding items; no new marine tender is evidenced.

Project anatomy

Scope, counterparties, and execution logic

Client / authority
Dubai Electricity and Water Authority (DEWA)
Delivery parties
Hassyan Water Company A P.S.C., SIDEM (Veolia), SEPCO III
Contract route
30-year build-own-operate independent water project under a DEWA water purchase agreement
Execution window
First 60 MIGD commissioned in Q1 2026; a further 120 MIGD expected during 2026; full Phase 1 completion scheduled for Q1 2027.
Works package
A 180 MIGD SWRO plant with seawater intake and outfall systems, marine pipelines, outfall diffuser sections, electrical facilities, potable-water storage, and intake-outfall capacity provision for a planned additional 60 MIGD phase.
Marine interfaces
The delivery chain connects offshore seawater abstraction, coastal pipeline corridors, brine discharge and diffuser performance with the adjacent Hassyan power-plant outfall and the environmental conditions of the Jebel Ali coastal area.
Commercial read
The principal marine works are already embedded in the SIDEM-SEPCO III EPC scope, so the near-term value is commissioning evidence, environmental performance, maintenance readiness, and future expansion interfaces rather than a new stand-alone intake or outfall tender.
Next milestone
Verify commissioning of the remaining two 60 MIGD blocks, final intake-outfall acceptance, marine water-quality performance, and the trigger for the planned 60 MIGD expansion.

Material change register

What changed, when, and what it proves

Only source-bound events that alter phase, scope, counterparties, delivery, completion, commissioning, or acceptance are listed. A change can advance the record without proving the next gate.

DEWA confirmed commissioning of Hassyan Block A

The first 60 MIGD block entered the installed water-capacity record, moving the project into phased commissioning while the remaining 120 MIGD, full marine-system acceptance, and sustained performance remain separate conclusions.

Read controlling source

First phase reported about 90 percent complete

The progress report narrowed the delivery window and put construction at an advanced stage. A percentage-complete statement left first water, accepted output, intake-outfall performance and commercial operation unverified.

Read controlling source

Hassyan IWP reached financial close

The owner announcement set the financed 30-year IWP delivery structure and committed development route. It contained no marine construction progress, commissioning result or accepted desalination capacity.

Evidence needed next

Verify commissioning of the remaining two 60 MIGD blocks, final intake-outfall acceptance, marine water-quality performance, and the trigger for the planned 60 MIGD expansion.

Decision watchpoints

  • Commissioning of the remaining 120 MIGD during 2026
  • Final intake, outfall pipeline, and diffuser acceptance
  • Brine-dispersion and marine water-quality monitoring
  • Future 60 MIGD expansion decision and shared marine capacity

Evidence reviewed date is not a project-event date.

IMWO changes phase, participants, scope, completion, or acceptance wording only when a dated source establishes the change. The review date records when the evidence set was checked; it does not claim that physical work changed on that date.

Source record

Dubai Electricity and Water Authority reporting says the 180 MIGD Hassyan seawater reverse-osmosis independent water project was about 90% complete in January 2026 and that all phases were scheduled for completion in the first quarter of 2027. DEWA's Q1 2026 results, published in May, confirm that the first 60 MIGD block had entered service and that a further 120 MIGD was expected during 2026. ACWA Power's project page identifies the 30-year BOO structure, Hassyan Water Company A, SIDEM and SEPCO III as the EPC consortium, and seawater intake and outfall systems as part of the facility. The project ESIA further confirms that ACWA Power's scope includes intake and outfall pipelines sized for the planned future 60 MIGD expansion, with the IWP outfall diffusers positioned close to the Hassyan power-plant diffusers after marine dispersion and environmental review.

Phase: commissioning. Evidence reviewed: 13 July 2026.
