Dubai Municipality received six proposals for the contract to construct a sewerage system interconnecting Jebel Ali sewage infrastructure to the municipality’s network.

The lowest bid of AED860m ($234m) was submitted by the local Nael Construction & Contracting. The low bid was 6.6 per cent lower than the AED920m proposal submitted by Kuwait’s MA Kharafi.

The full list of bidders and prices is:

Nael Construction & Contracting, AED860m

MA Kharafi, AED920m

Mabani Delma (local)/ Concord (local), AED990m

Detech Contracting (local)/ Gulermak (Turkey), AED1.2bn

Arabtec (local), AED1.25bn

Wade Adams (local), AED1.68bn

The project is part of the project to more than double the capacity of the Jebel Ali sewage network, which is a key part of the programme to upgrade Dubai’s wastewater network.

MEED reported in April 2016 that a joint venture of the local/Belgian Belhasa Six Construct and India’s Larsen & Toubro had been awarded the contract to build the second phase of Dubai’s Jebel Ali sewage treatment plant.

The municipality is also planning to build a deep-sewer tunnel and network in the Deira area of the emirate, similar to the Strategic Tunnel Enhancement Programme (STEP) in Abu Dhabi.
