Dubai extends $22bn tunnels investor prequalification

28 August 2024

Dubai Municipality has set a new deadline for firms to submit their statements of qualifications (SoQs) for the contracts to develop and operate various packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project.

According to a source close to the project, interested companies have until 21 October to submit their SOQs, which is six weeks later than the initial submission date of 5 September.

The investor prequalification process for the scheme, which is being procured on a public-private partnership (PPP) basis, comes after the client prequalified engineering, procurement and construction (EPC) contractors that can partner with the developers or investors to bid for the contracts.

DSST packages

Under the current plan, the $22bn DSST project is broken down into six packages, which will be tendered as PPP packages with concession periods lasting between 25 and 35 years.

The first package, J1, comprises Jebel Ali tunnels (North) and terminal pump stations (TPS). The tunnels will extend approximately 42 kilometres, and the links will extend 10km. 

The second package, J2, covers the southern section of the Jebel Ali tunnels, which will extend 16km and have a link stretching 46km.

W for Warsan, the third package, comprises 16km of tunnels, TPS and 46km of links.

J3, the fourth package, comprises 129km of links.

J1, J2, W and J3 will comprise the deep sewerage tunnels, links and TPS (TLT) components of the overall project.

J1, J2 and W will be procured under a design-build-finance-operate-maintain model with a concession period of 25-35 years.

J3 will be procured under a design-build-finance model with a concession period of 25-35 years. Once completed, Dubai Municipality will operate J3, unlike the first three packages, which are planned to be operated and maintained by the winning PPP contractors.  

The project’s remaining two packages entail the expansion and upgrade of the Jebel Ali and Warsan sewage treatment plants (STPs).

The prequalified EPC companies for packages J1, J2 and W are:

According to a source close to the project, packages J1 and W will be tendered together as separate contracts first, followed by J2 and J3, with the requests for proposals (RFPs) to be issued sequentially, staggered around six to 12 months apart.

The packages for the expansion and upgrade of the Jebel Ali and Warsan STPs will be procured in a process separate from the four DSST-DLT components.

The overall project will require a capital expenditure of roughly AED30bn ($8bn), while the whole life cost over the full concession terms of the entire project is estimated to reach AED80bn.

Sustainable project

The project aims to convert Dubai’s existing sewerage system from a pumped system to a gravity system by decommissioning the existing pump stations and providing “a sustainable, innovative, reliable service for future generations”.

Dubai currently has two major sewerage catchments. The first in Deira is Warsan, where the Warsan STP treats the flow.

The second catchment is in Bur Dubai, where the wastewater is treated at the Jebel Ali STP.

According to a source close to the project, the DSST will replace 120 pump stations, saving approximately 100 gigawatt-hours of electricity annually.

  • Dubai Municipality seeks Tasreef partner

    18 October 2024

    Dubai Municipality has issued a tender notice for a delivery partner to develop and implement a model tailored to the needs of the Tasreef programme, Dubai's planned AED30bn ($8.16bn) rainwater drainage network project.

    MEED understands the request for proposals targets technical and engineering advisory companies.

    Dubai Municipality expects to receive bids by 7 November, Fahad Al-Awadhi, director of drainage system and recycled water projects department, Dubai Municipality, said in a recent social media post.

    According to Al-Awadhi, the Tasreef  programme consists of three streamlines to enhance the effectiveness of Dubai's stormwater system:

    • Improvement of infiltration and sustainable drainage systems (Suds) and AI applications
    • Upgrade of stormwater systems in Deira, Bur Dubai and Jebel Ali
    • Proposed stormwater tunnels in Deira and Bur Dubai, as well as link tunnels in Jebel Ali

    In addition, the Tasreef programme will address storm event management, including raising awareness about storm impacts, implementing proactive risk control measures, developing marketing and procurement strategies, and establishing communication plans. 

    Al-Awadhi added: "The proposed stormwater tunnels, links and terminal pump stations aim to enhance the stormwater network’s capacity by 700% to handle up to 65 millimetres of rainfall per day. This program represents the largest rainwater collection project in a single system within the region."

    An early study is under way for Tasreef, which Sheikh Mohammed Bin Rashid Al-Maktoum, UAE Vice President and Prime Minister and Ruler of Dubai, approved in June, MEED reported in August

    A source familiar with the project said that Dubai Municipality is inclined to consider a public-private partnership (PPP) procurement model for the project.

    Sheikh Mohammed's approval of Tasreef came two months after a storm in April inundated Dubai, causing widespread flooding and damage to infrastructure and property in certain areas.

    The project will raise the emirate-wide drainage network’s capacity to more than 20 million cubic metres of water a day. It is envisaged to meet Dubai's needs for the next 100 years.

    The project is a continuation of drainage projects launched by Dubai in 2019, covering the Expo Dubai area, Al-Maktoum International Airport City and Jebel Ali.

    The rainwater drainage capacity through tunnels will reach 20 million cubic metres a day, with a flow capacity of 230 cubic metres a second.

    According to data from regional projects tracker MEED Projects, the Dubai Municipality Deep Tunnel Storm Water System (DTSWS) was first announced in 2014.

    It has several components, and the first two packages covering Jebel Ali were awarded between 2017 and 2018 and completed in 2022.

    The remaining packages of the master plan were on hold before the government's announcement on 24 June.

    The DTSWS project is separate from the Dubai Strategic Sewage Tunnels project, which is being developed under a PPP contracting model.

  • Saudi Arabia picks Ras Mohaisen preferred bidder

    18 October 2024

    A team comprising the local firms Acwa Power, Haji Abdullah Alireza & Partners Company and AlKifah Holding has emerged as the preferred bidder for a contract to develop the Ras Mohaisen independent water project (IWP) in Saudi Arabia.

    The state water offtaker received two bids for the contract in April this year.

    The only other company that submitted a proposal for the contract, Spain’s Acciona, is the reserved bidder, according to Saudi Water Partnership Company (SWPC).

    The Ras Mohaisen IWP will have the capacity to treat 300,000 cubic metres of seawater a day (cm/d) using reverse osmosis technology.

    It will also include storage tanks with a capacity of 600,000 cubic metres, equivalent to two operating days, and an electrical substation.

    The project is expected to reach commercial operation by the second quarter of 2028.

    It is initially expected that the SWRO plant will reach commercial operation by the third quarter of 2026.

    Ras Mohaisen is about 300 kilometres south of Mecca, on the Red Sea coast in Saudi Arabia’s Western Region.

    SWPC has appointed Netherlands-headquartered KPMG as the financial adviser, with UK-based Eversheds Sutherland acting as the legal adviser for the project.

    Register for MEED's 14-day trial access 

    Chinese energy storage solutions firm Hithium Energy Storage Technology Company (Hithium) and the local Nabilah AlTunisi have formed a joint venture that will manufacture battery energy storage systems (bess) in Saudi Arabia.

    The joint venture is called Hithium Manat. The planned manufacturing facility has an annual production capacity target of 5 gigawatt-hours (GWh), according to an official statement.

    Hithium launched energy storage solutions designed for the region's harsh environment during a solar and storage conference held in Riyadh.

    According to Hithium, "These systems feature advanced sandstorm protection and robust high and low-temperature designs, supporting ultra-long discharge cycles of 12+ hours."

    It added that the new product line is "customised to meet the unique demands of the Middle East and Africa region".

    Nabilah AlTunisi is the founder and owner of Hithium Manat's local partner.

    "This strategic alliance will not only provide access to world-class energy storage technology but also generate local employment opportunities, stimulate technological innovation and actively contribute to realising the kingdom's Vision 2030 objectives," AlTunisi said.

    Battery energy storage market

    In August, National Grid Saudi Arabia, a subsidiary of state utility Saudi Electricity Company, awarded the engineering, procurement and construction (EPC) contracts for three energy storage systems to Riyadh-based investment group Algihaz Holding. The estimated $800m projects are located in Najran, Madaya and Khamis Mushait.

    National Grid also recently tendered contracts for the construction of five battery energy storage systems with a total combined capacity of 2,500MW across the kingdom.

    The planned facilities, each with a capacity of 500MW or roughly 2,000 megawatt-hours, are located in or within proximity of the following key cities and load centres:

    • Riyadh
    • Qaisumah
    • Dawadmi
    • Al-Jouf
    • Rabigh

    Every utility in the region is procuring or planning to procure bess capacity in light of growing intermittent renewable power in their grids. 

    The overall capacity of deployed bess globally is expected to reach 127GW by 2027, up from an estimated cumulative deployment of 36.7GW at the end of 2023, a GlobalData report issued in June said.

    The report cited Chinese companies BYD and CATL and South Korean companies LG Energy Solutions and Samsung SDI among the top battery technology providers globally.
