Dubai Municipality has invited contractors to prequalify for a contract to build a sewerage and stormwater system in the Nadd Hessa area. The project is being procured through the Sewerage and Recycled Water Projects Department. The submission deadline is 2 April.

Nadd Hessa is an emerging development area, located between Dubai Silicon Oasis and Academic City along the E311 corridor.

It has been earmarked for future residential expansion, with enabling infrastructure now being tendered to support planned housing and community developments in the area.

The scheme, known as DS 328/1–C1, covers the construction of sewerage and stormwater infrastructure, including approximately 12.4 kilometres of sewerage lines with diameters of up to 400 millimetres.

The scope also includes about 14km of stormwater lines with diameters of up to 1,000 millimetres. In addition, the project involves around 500 metres of microtunnelling works for both sewerage and stormwater networks.

The municipality is currently prequalifying contractors for several upcoming water projects, including the expansion of the Jebel Ali sewage treatment plant (STP) phases one and two. The upgraded facility will be capable of treating an additional sewage flow of 100,000 cubic metres a day (cm/d). Bid submissions for this project are also due by 2 April.

Two separate consultancy tenders were issued in March. One involves a study to develop a sustainable urban drainage systems strategy across the emirate. The other covers a review of the emirate’s sewage treatment and recycled water distribution strategy.
