One Bangkok, Thailand’s first fully integrated district, has set a benchmark for sustainability and urban innovation as
the country’s pioneer site to obtain the LEED-Neighborhood Development Platinum certification. This accolade reflects
the district’s steadfast commitment to sustainable design, smart-city principles, and community-oriented living. These efforts are all rooted in its core values of People Centricity, Sustainability, and Smart City integration. Designed as a vibrant mixed-
use development, One Bangkok seamlessly integrates retail, commercial, residential, and hospitality. This design fosters a
dynamic and diverse community. With 50% of the project area dedicated to green, open spaces, and tree-lined
sidewalks designed to enhance walkability, One Bangkok exemplifies a forward-thinking approach to creating a
healthy, refreshed, and more connected urban environment.
At the heart of the developer’s vision lies a robust focus on efficient resource use and ecological preservation.
Partnering with Veolia, One Bangkok implemented advanced water and wastewater management solutions. These efforts help achieve
a set of ambitious sustainability goals. This partnership reflects the district’s mission to reduce its ecological footprint
and operate responsibly. It aims to provide a vibrant, people-centric community.
Addressing Water Sustainability Challenges
Sustainability has been a guiding principle for One Bangkok since its inception, informing every aspect of its master
plan, development, and operations. With resource efficiency in mind at the planning stage, the Veolia team developed
a centralized water management system that prioritizes reuse and recycling. One major challenge was treating and
reusing wastewater from every building while harvesting rainwater. This strategy aims to expand recycled water capacity, minimize
reliance on potable water, and enable a significant reduction in overall water consumption.
Solutions Designed for Maximum Efficiency
Veolia rose to the challenge by designing an integrated water treatment system tailored to meet One Bangkok’s
objectives for water recycling and efficiency. Spidflow ® , a cutting-edge high-rate clarification process, makes its debut
in the Asia-Pacific region as a cornerstone of One Bangkok’s water management system. This innovative technology
offers flexibility and responsiveness to variations in the quality of water to be treated. Such qualities make it essential for a project
of this scale and complexity. The versatility of this solution enables efficient clarification across a spectrum of water
types, encompassing drinking water, process water, and both municipal and industrial wastewater. With Spidflow ® ,
Veolia provides One Bangkok with a sophisticated yet sustainable solution to manage complex water needs. This solution
demonstrates scalability and the potential for wider adoption in urban environments across the region.
Furthermore, by combining Spidflow ® with the AnoxKaldnes ® Moving Bed Biofilm Reactor (MBBR), a biological
treatment technology, Veolia offers a comprehensive approach that ensures pollutant removal. Using biofilm carriers
suspended in wastewater, the MBBR offers stable and efficient treatment. It showcases a commitment to exceeding stringent
sustainability standards, positioning One Bangkok at the forefront of environmentally responsible urban development.
At the core of One Bangkok’s water management system lies the Multiflo™ clarification process. This process combines
coagulation, flocculation, and counter-current lamella settling into one compact and high-performance solution. This
multi-stage process was thoughtfully designed to address the challenges of tomorrow. It effectively treats both
stormwater and tertiary wastewater for the district. Its adaptability and compact footprint proved fitting for One
Bangkok’s urban setting, where space constraints necessitate innovative and forward-thinking solutions.
Together, Veolia’s integrated technologies empower the reuse of 1,200 to 1,500 m³ of water daily. This is equivalent to half
an Olympic swimming pool. When operating at full capacity, this system will treat and recycle a volume comparable to
four Olympic swimming pools, or approximately 10,000 m³ of water. This substantially decreases water consumption and
supports One Bangkok’s bold environmental targets.
Smart monitoring technologies are seamlessly integrated across the water system to ensure optimal performance.
Leveraging real-time data, the system supports robust, data-driven water management. More importantly, it enables continuous
monitoring for adjustments as needed. This proactive approach also facilitates predictive maintenance. It enhances
operational efficiency and minimizes long-term costs. These efforts support One Bangkok’s overarching “Reuse and
Recycle” practice, contributing to a projected annual savings of 3.7 million m³ of potable water—enough to supply
more than 11,000 urban households for an entire year 1
With Veolia’s tailored solutions and support, One Bangkok is setting a precedent for future-ready urban development.
At full operational capacity, its systems will enable the district to recycle 75% of wastewater for non-potable
applications.
A Model of Sustainability for Urban Spaces
One Bangkok’s holistic sustainability strategy encompasses advanced water management, energy efficiency, and
wellness-focused design. At its core, an innovative district cooling system works in tandem with a state-of-the-art
command center, operating around the clock. This centralized infrastructure highlights the power of technology. It enhances both operational efficiency and environmental stewardship.
In alignment with Veolia’s GreenUp strategic program—which focuses on ecological transformation through innovative
solutions that depollute, decarbonize, and regenerate resources—the One Bangkok project demonstrates the
transformative potential of advanced water treatment technologies in urban developments. By implementing tailored
solutions with well-harmonized technologies, Veolia’s partnership with One Bangkok has achieved significant
milestones in water recycling and resource optimization. Beyond setting a new benchmark, the collaboration serves to
foster resilient communities. It offers a blueprint for future-ready urban spaces, inspiring the creation of smarter, greener cities.
