Dubai seeks contractors for Jebel Ali STP expansion

16 February 2026

Dubai Municipality has invited contractors to prequalify for a contract covering the expansion of the Jebel Ali sewage treatment plant (STP) phases one and two.

The upgraded facility will be capable of treating an additional sewage flow of 100,000 cubic metres a day (cm/d).

The scope includes the design, construction and commissioning of infrastructure and systems required to support the increased capacity.

The bid submission deadline is 2 April.

Located on a 670-hectare site in Jebel Ali, the original wastewater facility has a treatment capacity of about 675,000 cm/d following the completion of phase two in 2019, combining approximately 300,000 cm/d from phase one and 375,000 cm/d from phase two.

As MEED understands, the project is part of long-term plans to treat about 1.05 million cm/d a day once all future phases are completed.

The main element of the expansion, which is estimated to cost $300m, involves modifications to the secondary treatment process at Jebel Ali STP phase two.

This includes conversion to Moving Bed Biofilm Reactor or Integrated Fixed-Film Activated Sludge systems.

The project also includes decommissioning existing surface aerators. New blowers and associated works will be installed as part of the upgrade.

UK-headquartered KPMG and UAE-based Tribe Infrastructure are serving as financial advisers on the project.
