Aqaba-Amman switches to existing intake assets and a canyon outfall

Original IMWO excavation balance for Aqaba-Amman SEPCO intake and DN2800 canyon outfall context: 20,000 cubic metres indicative total, 8,500 for backfill reuse and 11,500 for onshore disposal

Aqaba-Amman's October marine addendum replaces the proposed new intake lagoon with the existing SEPCO lagoon and pumping station. It relocates the outfall to a canyon and describes a DN2800 HDPE installation with about 20,000 m3 of indicative excavation, including 11,500 m3 requiring onshore disposal.

October design replaces the December 2025 marine construction assumptions

The October 2026 Rev 0 addendum supplies the revised marine design and indicative method. Its existing-approvals statement is attributed to Chapter 9; activity permits still require authority coordination. DFC announced loan and equity-investor insurance approvals on 16 September. EBRD retains Approved status. Financial close, NTP and installed works require current project confirmation. The December 2025 scheme is retained as a dated comparison.

Shore receiving and disposal capacity set part of the offshore production cycle

The revised route addresses bathymetry, diving access and proximity to existing marine assets. Its selected diffuser lies at about 16-27 m depth within the project's 35 m diving limit. Dredging, pipe preparation, ballast, barge movements, shore unloading and truck disposal now need a common daily cycle; the proposed onshore surplus represents 57.5% of excavation.

Evidence conclusion

Fix the port and receiving arrangements before committing the installation spread

The indicative method uses shore work to chainage 60, crane-barge work from 60 to 110 and pipe placement seaward to about chainage 195. Royal Navy Port storage and preparation areas remain under discussion. A tender programme should link ecological release, excavation, shore receiving, pipe-string preparation and installation, with final volumes set by design, ground and the subcontract method. Reusing SEPCO assets also makes tie-in and existing-operation arrangements part of the marine work package.

Outstanding evidence

  • Financial close, notice to proceed and marine work-area release
  • Existing SEPCO asset condition, intake tie-ins and operating interfaces
  • Final canyon-outfall geometry and subcontract construction method
  • Royal Navy Port pipe, precast and rock-handling arrangements
  • Coral translocation, turbidity controls and onshore receiving/disposal capacity
  • Connection, testing and commissioning across marine, desalination, power and conveyance
