Dubai extends bid deadline for sewerage tunnels links contract

9 February 2026

 

Dubai Municipality has extended the bid submission deadline for the Phase 2 Links package under the Dubai Strategic Sewerage Tunnels (DSST) public-private partnership (PPP) project.

The DSST scheme is one of Dubai’s largest planned infrastructure PPPs, with an estimated total cost of about AED80bn ($22bn).

The new bid submission deadline for Phase 2 Links is 30 June. The initial deadline was 30 April.

Phase 2 Links is the third package to be tendered by the municipality’s sewerage and recycled water projects department, following J and W, which opened for bidding in November.

According to sources, the evaluation of technical bids for these packages is complete, with the commercial bids to be opened this week.

The main contracts for J and W are expected to be awarded in April.

The three packages cover construction works that were previously categorised under the Warsan Strategic Tunnel Scheme (Package W) and the Jebel Ali Strategic Sewerage Scheme (J1 North, J2 South, J3 Jebel Ali Links).

These packages have now been restructured and renamed.

The project masterplan comprises over 200 kilometres of sewer links as well as the construction of two sets of deep tunnels terminating at terminal pump stations at Warsan and Jebel Ali Sewage Treatment Plants (STPs). 

The request for proposals (RFP) for Phase 2 Links was issued to prequalified developers “pursuant to the PPP request for qualifications dated 24 July 2024” and “the PPP request for qualifications refresher dated 19 September 2025”, the municipality said.

In September last year, Dubai Municipality launched a refresher request for qualifications for the second package of the DSST project. 

The update applied to developers that were originally shortlisted under the first prequalification process.

Under the scope of work, the appointed developer will be responsible for the development, financing, design, engineering, and procurement of the links package.

It will also manage supply, manufacturing, testing, construction, erection, installation and commissioning works.

Additionally, the scope includes warranty, insurance, ownership, operation, maintenance and handback, the municipality said.
