Dubai Municipality has confirmed it has awarded four contracts worth AED3bn ($817m) to expand the emirate’s stormwater drainage network by about 100 square kilometres under phase three of the Tasreef programme.

The projects will cover Jumeirah, Umm Suqeim, Al-Quoz, Al-Barsha, Al-Wasl and Al-Marmoom. The works include constructing and extending main stormwater drainage lines with diameters of up to three metres.

The four packages are part of Dubai’s AED30bn Tasreef programme, which aims to increase the emirate’s stormwater drainage capacity by 700% and reduce costs associated with pumping stations, network operations and maintenance by 20%.

The contracts have been awarded to China State Construction Engineering Corporation (CSCEC) and three local firms: Arifco Group, Nael Construction & Contracting (NCC) and Detech Contracting. Dubai Municipality did not state which projects the awards relate to.

According to sources, the contract awards include packages TF-15-C1, TF-15-C2 and TF-13-C1.

The first package, TF-15-C1, involves the construction of 21 kilometres of main and secondary drainage lines along Al-Wasl Road and in surrounding areas. It will cover Za’abeel 2, Al-Wasl, Jumeirah 1 and 2, Al-Bada’a, Al-Satwa and Dubai World Trade Centre. The estimated $100m contract was awarded to Detech in July, as exclusively reported by MEED.

The second package, TF-15-C2, covers the corridor between Sheikh Zayed Road and Al-Khail Road. It includes about 14km of main drainage lines serving Al-Quoz Industrial Areas 1, 3, and 4, and Al-Barsha 1. In July, MEED reported that CSCEC had won the engineering, procurement and construction contract for this project.

The third package, TF-13-C1, covers Al-Marmoom, where 23km of drainage infrastructure will be developed. According to a source, Arifco has been awarded this contract.

The final package covers Jumeirah and Umm Suqeim, where about 42km of main drainage lines will serve Umm Suqeim 1, 2 and 3; Umm Al-Sheif; Jumeirah 3; Al-Safa 1 and 2; and Al-Manara.

In May, MEED reported that NCC had been awarded a contract to build a sewage and stormwater drainage system, DS-204. However, it is unconfirmed whether this relates to the same project.

Earlier, in February, the municipality confirmed it had awarded contracts for five new projects under phase two of the programme to expand and strengthen Dubai’s stormwater drainage network.

These included two contracts awarded to Detech and one to CSCEC for stormwater drainage infrastructure. In addition, two consultancy contracts were awarded for the study and design of drainage systems in selected areas across the emirate.

Cumulatively valued at AED2.5bn, the new projects will serve 30 vital areas, spanning approximately 430 million square metres and supporting an estimated population of three million residents by 2040.

Previously, in April 2025, an earlier package of awards was announced under phase one of the Tasreef programme. The overall masterplan aims to expand Dubai’s rainwater drainage capacity by 700% by 2033.
