Dubai awards $392m Tasreef contracts

14 April 2025

Dubai Municipality has awarded contracts worth AED1.439bn ($392m) for four major projects under the Tasreef project to develop, rehabilitate and expand Dubai’s stormwater drainage network.

According to data first published by MEED Projects, the local firm De Tech Contracting won a package worth $136m.

De Tech won the contract for the West Deira stormwater system upgrade and rehabilitation, which involves the construction of a sewerage network and a gravity stormwater network.

The projects form part of Dubai’s broader commitment “to building sustainable and climate-resilient infrastructure”, Dubai Municipality said in a statement published by Emirates News Agency (Wam).

The entire Tasreef project will serve key areas across the emirate, including Nad Al-Hamar, the vicinity of Dubai International airport, Al-Garhoud, Al-Rashidiya, Al-Quoz, Zabeel, Al-Wasl, Jumeirah and Al-Badaa.

“The commissioned works are designed to provide sustainable and innovative solutions to mitigate flooding risks, enhance the efficiency of existing networks, and improve overall service levels,” Dubai Municipality said.

It added: “More than 36 kilometres of new drainage lines will be constructed, linking to the main Tasreef tunnel, which will ultimately connect drainage systems across the emirate.”

In October, Dubai Municipality issued a tender notice for a delivery partner to develop and implement a model tailored to the needs of the Tasreef programme.

MEED understands that the request for proposals is targeted at technical and engineering advisory companies.

The Tasreef programme consists of three streams to enhance the effectiveness of Dubai’s stormwater system:

  • Improvement of infiltration and sustainable drainage systems and artificial intelligence (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. 

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.

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 last year 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, which is hoped will 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 in 2017 and 2018 and completed in 2022.

The remaining packages of the masterplan 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 framework.

  • Taqa raises $750m to finance water projects

    30 July 2026

    Abu Dhabi National Energy Company (Taqa) has issued a $750m five-year blue bond to finance sustainable water and wastewater management projects.

    The company said the transaction is the largest blue bond issuance in the Europe, Middle East and Africa region. It is also the largest blue bond issued by an integrated power and water utility globally.

    Issuing the bond allows Taqa to raise money from investors specifically to support water-related environmental projects. These can include desalination, wastewater treatment, water recycling and reuse, and infrastructure that improves water efficiency.

    It is the first blue bond issued under Taqa’s Green and Blue Finance Framework, and follows another blue financing transaction in the UAE earlier this year.

    On 8 January, Dubai-based Emirates NBD bank announced the completion of a $1bn dual-tranche sustainable bond issuance, comprising a $300m blue tranche with a three-year tenor and a $700m green tranche with a five-year tenor.

    Emirates NBD said at the time that the $300m tranche was the largest blue bond issued in the UAE and GCC. The proceeds are intended to support marine conservation and sustainable water projects, while proceeds from the green tranche will finance green initiatives.

    Taqa launched its original Green Finance Framework in 2023 and updated it in 2026 to include blue financing instruments. The latest issuance takes its total green and blue labelled bond issuances to $2.6bn since 2023.

    The Taqa financing also comes as the company expands and modernises its water infrastructure. Taqa is targeting reverse-osmosis technology for 66% of its desalination capacity by 2030, up from about 40% in 2025.

    In June, Taqa awarded a contract for the construction of a 1-million-cubic-metre emergency lagoon in Abu Dhabi. The project will be developed in two phases.

    Phase one has a capacity of 500,000 cubic metres and is planned to be completed within 18 months of the contract award.

  • UAE renewables firm secures $375m in financing

    30 July 2026

    Positive Zero, the UAE-based renewable energy firm, has announced the successful closing of a financing facility of up to $375m.

    The long-term financing was arranged by Paris-headquartered Natixis Corporate & Investment Banking (Natixis CIB) and Saudi Arabia-based The Arab Energy Fund.

    Natixis CIB also acted as financial adviser, facility agent, security agent and green loan coordinator for the transaction.

    “The non-recourse financing is the first transaction of its kind in the region for a diversified portfolio of decentralised infrastructure assets, including distributed solar power generation, energy efficiency and clean mobility solutions,” Positive Zero said in a statement.

    “The financing will provide substantial long-term capital to support Positive Zero’s continued expansion in the United Arab Emirates, Saudi Arabia, Bahrain, Oman and Qatar, funding the growth of its distributed infrastructure portfolio, capital expenditure programme and strategic development initiatives,” the Dubai-based firm said.

    The new debt facility secured by Positive Zero builds on US-based BlackRock’s investment of up to $400m in the company in 2023, “further strengthening the company’s capital structure and supporting the next phase of its growth”.

    Positive Zero has the largest distributed solar capacity in the region with more than 500MW in operations and under construction, avoiding more than 450,000 metric tonnes a year of carbon emissions.

    The company has also saved over 100 million kilowatt-hours (kWh) in energy consumption across its client portfolio through its energy-efficiency solutions.

  • US-Saudi consortium to build $5bn refinery outside Strait of Hormuz

    30 July 2026

    Register for MEED’s 14-day trial access 

    A consortium of privately owned US and Saudi companies has announced an investment commitment of $5bn to build an integrated oil refining, storage and export facility outside the volatile Strait of Hormuz shipping lane.

    After three years of evaluating sites across the Gulf, the consortium has shortlisted three GCC locations beyond the Strait of Hormuz. Discussions have advanced over the past two years, with a preferred site expected to be selected by the end of 2026.

    The consortium, Mera Oil, comprises Fort Worth, Texas-based MWG Enterprises; the US-based Patel Family Office; and PWS, an associate company of Saudi Arabia’s AHQ Group.

    Mera Oil said it remains open to alternative proposals that meet its infrastructure, resilience and development requirements.

    The proposed project will feature a 200,000-barrel-a-day refinery, deepwater port connectivity, large-scale crude and refined-product storage, and marine export facilities.

    A pre-feasibility study covering refinery design, logistics, capital requirements and execution planning is at an advanced stage.

    Once a host jurisdiction is confirmed, the project will proceed to detailed site assessments and engineering design, with mechanical completion targeted for end-2029, followed by commissioning and the start of commercial operations.

    The consortium plans to focus on producing high-specification middle distillates, including ultra-low sulphur diesel and jet fuel, for selected international markets.

    The project is expected to occupy about 1,200-1,500 acres of port-connected industrial land and could create up to 3,000 direct jobs, and around 15,000 indirect and induced jobs, during construction and operations.

    Mera Oil is also progressing discussions with feedstock suppliers and expects financing to include sponsor equity, sovereign and institutional investment, project finance, export-credit support and sharia-compliant funding structures.

    “Designed as a route-resilient energy hub, the development aims to strengthen regional manufacturing, logistics, technical expertise and energy security,” Mera Oil said.

    The first phase of the planned investment will “incorporate energy-efficient refining technologies, emissions-control systems, and potential future capabilities including sustainable aviation fuel co-processing and carbon management.”
