Dubai Strategic Sewerage Tunnels

Dubai has approved a $22BN network of deep sewer tunnels, up to 90m underground, to replace a patchwork system of over 150 pumping stations that has occasionally spilled onto the city's streets.

Dubai Municipality is procuring the Dubai Strategic Sewerage Tunnels as a PPP with an ultimate investment of $22 billion; in early June 2026 it selected two consortia for Package W (Warsan, about $3 billion) and Package J (Jebel Ali, about $2 billion)^[2]
Package W is led by Etihad Water & Electricity with Tamasuk and Alkhorayef; Package J by Vision Invest and Suez; a Links package of over 200 km of deep tunnels is under tender; packages were reconfigured and retendered in November 2025^[2]
Tunnels are 3 m in diameter and up to 90 m deep, gravity-fed, with two main tunnels (Bur Dubai Deep Tunnel, 50 km, and Deira Deep Tunnel, 25 km); more than 150 legacy pumping stations are to be decommissioned^[2]
Urgency followed the April 2024 flooding^[2]
The concession is 30-year DBFOM at 80:20 debt-to-equity; tunnel contracts are expected to be awarded in January 2030, with completion targeted across 2030-2056^[2]
Earlier scale was smaller: a 2017 report described an AED30 billion (US$8 billion) system with construction expected from 2019 and about 100 pumping stations replaced, since superseded by the newer figures^[3]

The Dubai Strategic Sewerage Tunnel megaproject to be 'development of the century' – WaterWorld
waterworld.com· Published Sep 1, 2025· 14% of score
WaterWorld's article describes construction expected to commence "as soon as 2019" over a six-year, two-phase build - a much more optimistic early timeline than the pin's current estimated 2032 completion date, indicating the project has since slipped substantially relative to this earlier projection.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
