Challenges and Opportunities
In the real estate and retail property business, water is a critical resource that supports operations and is fundamental to long-term business sustainability. However, Central Pattana Public Company Limited faces several challenges, particularly in regions affected by water scarcity and severe flooding, such as the Northern and Northeastern areas. These challenges may directly impact operations and lead to higher costs if not properly managed.
Inefficient water management can not only disrupt operations but also lead to increased greenhouse gas (GHG) emissions. Inadequate wastewater treatment could contaminate water sources, potentially causing community complaints and raising concerns regarding community rights—especially when public water resources are used without due consideration of local impacts. These factors underscore the need for a robust water management system that accounts for the unique water needs of each shopping center location, including public spaces, restrooms, landscaping, cleaning, and tenant areas with varying water consumption patterns. For example, restaurants require water for food preparation and equipment cleaning, while retail shops use it mainly for space maintenance.
Nevertheless, Central Pattana recognizes that effective water management and water reuse not only reduce costs but also enhance resource efficiency. Proactive measures to address water scarcity and climate-related risks can help minimize business impacts in the long term, strengthening the Company’s resilience in the face of uncertainty.
Implemented a structured water management system tailored to the specific water needs of each shopping center location.
Management Approach and Value Creation
Central Pattana is committed to sustainable water and wastewater management that balances project development, efficient resource use, and concrete environmental responsibility. The Company adopts the 3Rs principle—Reduce, Reuse, and Recycle—across all shopping centers nationwide to support its water-related goals 20% of total water reused by 2025, 100% of water reused in applicable activities by 2025 and 10% reduction in water intensity by 2030
In 2024, the Company installed recycled water systems in 17 projects, producing a total of 596,762 cubic meters of recycled water—4.7% of total corporate water consumption and 14% of water use at locations with installed systems. Treated water was reused in suitable activities, such as sanitation systems and green space irrigation. This resulted in 14.9% of recycled water being reused in applicable activities—an increase from the previous year—demonstrating strong potential to scale water circularity effectively.
In terms of wastewater management, the Company strictly controls its wastewater treatment systems, selecting high-efficiency technologies appropriate to each site. These include the Sequencing Batch Reactor (SBR) system, Deep Shaft treatment, and government-operated systems in select areas. In 2024, Central Pattana discharged 5.75 million cubic meters of treated water into public sources and sent an additional 2.2 million cubic meters to third-party treatment facilities. There were no complaints regarding wastewater management quality during either construction or operational phases.
The Company also integrates new technologies and innovations to improve water efficiency, such as using ozone in cooling tower systems to reduce make-up water demand and minimize bleed-off, as well as reusing condensate from air-conditioning systems to replace freshwater use in various processes.
Central Pattana acknowledges the link between water use and greenhouse gas emissions throughout water production, transport, and treatment processes. Therefore, water management is embedded into the Company’s Net Zero 2050 Roadmap as a key decarbonization measure. This initiative also supports the achievement of the United Nations Sustainable Development Goals (SDGs), particularly Goal 6: Clean Water and Sanitation, Goal 12: Responsible Consumption and Production, and Goal 13: Climate Action.
Wastewater Treatment Technologies and Measures
Central Pattana Public Company Limited employs advanced wastewater treatment technologies, including Sequencing Batch Reactors (SBRs) and preliminary treatment processes before discharging water back into public systems. The Company enforces strict standards for wastewater management to prevent environmental impacts, while also promoting upstream waste management and encouraging waste sorting and recycling to maximize the value of utilized resources.
