Dubai Municipality's planned network includes more than 200 kilometres of sewer connections and deep-tunnel systems linked to wastewater pumping stations in Warsan and Jebel Ali. Its first two packages carry an estimated capital cost of about $5 billion. The wider public-private partnership is valued at AED80 billion ($22 billion) and aims to move Dubai's sewage network from pumping to gravity. Available follow-up reporting does not independently confirm the reported W and J partner selections or any concession awards.
The sewage tunnels are part of a long-term infrastructure plan. They are separate from Dubai Municipality's programme to expand stormwater drainage capacity.
Package W is estimated to require about $3 billion in capital expenditure. It is slated to be led by Emirates Water and Electricity Company alongside Saudi Arabia's Tamask Holding. Alkhorayef Water and Power is also named among the partners. China State Construction Engineering Corporation is included in the group assigned to the engineering, procurement and construction work.
Package J is estimated at less than $2 billion. Saudi Arabia's Vision Invest is set to lead the selected consortium with France's Suez. The engineering, procurement and construction contract is expected to go to a group including China Railway Construction Middle East. Local contractor DITEC Contracting is also named. These reported selections do not establish that a concession has been awarded; available follow-up coverage does not confirm one.
The Links Phase Two tender was issued in January, with bids due by 30 June. At least two groups are preparing offers. One combines Emirates Water and Electricity Company with Emirates Civil Engineering. National Marine Dredging Company and China Railway 11th Bureau Group are named as engineering, procurement and construction contractors. Veolia is expected to operate the project.
Plenary is leading a second consortium. DITEC Contracting and Turkey's Kalyon Construction are also preparing bids for engineering, procurement and construction work.
All three packages are planned under 30-year concessions covering design and construction, financing, operation and maintenance. The proposed gravity-fed network would let Dubai replace existing sewage pumping stations and meet long-term capacity needs. The project was among the AED80 billion private-sector partnership investments approved by Dubai Crown Prince Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum in June 2023.
The sewage overhaul is separate from building regulation. Dubai's parallel municipal responsibility for building safety renewals was covered in a separate update.
Recent MEED reporting concerns four Tasreef stormwater drainage projects, not the strategic sewage tunnel packages. One project's reported scope includes 18 kilometres of stormwater pipelines, up to 1,800 millimetres in diameter, plus 3.5 kilometres of gravity sewer pipes, up to 1,000 millimetres in diameter. The pipes would connect developing areas of Dubailand to the existing stormwater network.
Dubai Municipality invited bids for construction supervision across the four Tasreef projects, with submissions due on 29 October 2026, according to Zawya's tender update. A separate construction tender for project TF-07-C1 had a 22 October 2026 bid deadline. Those dates and project details concern Tasreef; available reporting does not link TF-07-C1 to sewage packages W or J. Reuters' distribution of the Tasreef update also concerns stormwater works and does not confirm the sewage package awards.
