WASTEWATER-TREATMENT TECHNOLOGY: Dubai is at the forefront of adopting cutting-edge technologies in wastewater treatment facilities, employing advanced triple and tertiary treatment techniques to generate top-tier reclaimed water. This reclaimed water serves various purposes, including irrigation, central cooling, and the creation of artificial lakes.

RECLAIMED WATER: Impressive greenery and world-class infrastructure are two of the remarkable features of Dubai and the UAE. Reclaimed water in Emirate serves various purposes, including irrigation, central cooling, and the creation of artificial lakes. In 2022, Dubai used 134 million cubic metres of recycled water was reused to keep the emirate green. Image Credit: Clint Egbert/Gulf News

BENEFITS OF WASTEWATER TREATMENT: Extensive water reuse in a desert clime offers advantages that go beyond resource management. Dubai saves about Dh2 billion every year from reusing water. More fundamentally, this water reuse strategy seamlessly aligns with the emirate's 2050 Net Zero Carbon Emissions Strategy. By preserving valuable groundwater reserves for future generations and diminishing the energy-intensive desalination process, this endeavor plays a role in decreasing greenhouse gas emissions.

INITIATIVE: Dubai initiated its water reclamation efforts in the late 1960s. The inaugural wastewater treatment facility, founded by Dubai Municipality in Al Khawaneej in 1969, set the groundwork for subsequent initiatives.

EXPANSION: With the city's rapid expansion, there was a corresponding surge in the need for wastewater treatment and recycled water. The Warsan facility, established in 1981, expanded its capacity to 260,000 cubic meters per day, and the Jebel Ali plant, initiated in 2006, significantly augmented the city's daily water recycling capacity to approximately 560,000 cubic meters.

IRRIGATING 10,400 HECTARES: In Dubai, reclaimed water is employed to irrigate approximately 10,400 hectares of land, including public gardens, green spaces, and landscaped areas within property developments. On a monthly basis, roughly 22 million cubic meters of reclaimed water are utilized for irrigation, leading to significant cost savings. Image Credit: Nabil Naz/Gulf News reader

4.5 BILLION CUBIC METRES OF RECLAIMED WATER: From 1980 to 2022, Dubai generated more than 4.5 billion cubic meters of reclaimed water. This reduction in the use of desalinated water and groundwater led to significant annual savings of around Dh2 billion. By 2030, Dubai's goal is to double its recycled water production to surpass 8 billion cubic meters. A flower bed outside the One Central building in Dubai's financial district.

CURBING CARBON EMISSIONS: To mitigate carbon emissions from sewage treatment processes, Dubai Municipality's Waste Management and Sanitation Department has adopted anaerobic digestion in central treatment plants. This approach reduces energy consumption and produces biogas, significantly reducing carbon emissions from methane gas. Some of this biogas is used for heating aerobic digestion tanks and drying sludge to produce thermally-treated organic fertiliser. An impressive green and flower patch in Dubai.

CLEAN TECH: Dubai shows the way for sustainability with the latest clean tech, including the use of solar and pumped hydro-electric power. The Mohammed bin Rashid Al Maktoum Solar Park, spread over an area of 77 km² in Saih Al-Dahal, about 50 kilometers south of the city of Dubai, is one of the world's largest renewable projects based on an independent power producer model. The Hatta pumped hydroelectric project being developed at Hatta, Dubai, will be the first of its kind power project in the Arabian Gulf region. Set for completion in 2024, the 250MW project is being developed by the Dubai Electricity & Water Authority. Each megawatt can typically power up to 1,000 homes for 365 days. The Hatta pumped hydro facility will have a storage capacity of 1,500 megawatt hours and a lifespan of up to 80 years. Image Credit:

YEAR OF SUSTAINABILITY: As the UAE commemorates the Year of Sustainability, Dubai's water recycling and resource management initiative serves as an inspiring blueprint for other urban areas and regions. Through continuous investments and careful strategic planning, Dubai consistently improves its water recycling infrastructure. With each use of reclaimed water, Dubai advances towards a future that is more balanced and resource-aware. Dubai makes extensive use of drip irrigation technology.

DRIP IRRIGATION: The United Arab Emirates is one of the top 10 most water-scarce countries in the world. To address this challenge, the country has adopt drip irrigation system, which employs perforated tubes positioned along the ground or buried close to the plant roots to deliver water directly to the plants' base. This method not only significantly reduces water evaporation but also consumes 25% less water compared to spray irrigation systems. Photo shows horticulture staff at work to keep the city green.

RECOGNITION: Dubai’s excellence in water recycling garnered global recognition. In 2022, Dubai Municipality secured first place in the International Water Reuse and Recycling Award, organised by the International Desalination Association (IDA). The Jebel Ali Sewage Treatment Plant Expansion Project (Phase 2) received the award in the Exceptional Utility Leader category. Image Credit: Clint Egbert/Gulf News
