Enhancing Water Efficiency and Reuse
Water Management Project
Central Retail is committed to managing water resources efficiently, focusing on assessing water-use patterns, identifying branches with high water consumption, and determining appropriate approaches to improve water-use efficiency. This includes promoting opportunities for water reuse and proper wastewater management to support the efficient and sustainable use of water resources. In 2024, Central Retail conducted water-use assessments at three Robinson Lifestyle shopping centers: Surin, Sakon Nakhon, and Phetchaburi. The assessments focused on understanding water-use patterns and identifying opportunities to improve water-use efficiency at each location, with the results used to determine water-management measures appropriate to each branch's context. Central Retail initiated new water-efficiency improvement projects, such as installing wastewater treatment systems for toilet wastewater, and plans to expand water-use assessments to additional key branches in the future to further improve water-use efficiency. In addition, Central Retail implemented water-reduction measures through the installation of water-saving equipment, such as automatic faucets and water-efficient sanitation systems, as well as improvements to cleaning and maintenance processes to reduce water use. Central Retail also conducted campaigns to raise employee awareness of the importance of reducing water consumption in daily life and at work.
In 2025, Central Retail expanded water-use assessments to four additional branches: Suphan Buri, Kanchanaburi, Prachin Buri, and Roi Et, focusing on branches with high levels of water consumption to identify opportunities to reduce water use and increase water reuse. The assessment results supported the implementation of Water Reuse measures at branches with potential, enabling approximately 1,200-1,500 cubic meters of water per month per branch to be reused through the Water Reuse system.
Water Efficiency Improvement and Water Reuse Project
Central Retail focuses on improving water-use efficiency and reducing reliance on new water sources by using the results of water-use assessments to develop measures to reduce water consumption and reuse water. These measures cover improving the efficiency of water-using equipment, rainwater harvesting, reusing water from various systems, and reusing treated water for appropriate activities, while regularly monitoring wastewater quality to ensure compliance with established standards. Since 2022, Central Retail has implemented measures to improve water-use efficiency by using treated water to produce Recycle Water, thereby improving the efficiency of water-resource use and reducing the use of water from new sources.
In 2025, Central Retail expanded these measures to cover nine Robinson Lifestyle shopping centers: Kanchanaburi, Suphan Buri, Prachin Buri, Roi Et, Chonburi, Chaiyaphum, Phetchaburi, Surin, and Sakon Nakhon. The initiative reduced water consumption by approximately 3,000 liters per month per branch and saved more than THB 1.7 million per year in water-resource costs. The recycled water produced is used for cooling chillers through Cooling Towers and in Flushing Systems.
Water Scarcity and Agricultural Resilience Project
Due to climate change, farming communities in Nan Province face recurring droughts and water insecurity. In address this issue, Central Retail has extended its environmental impact to Thailand’s Nan Province through a water resource development project designed to help farming communities cope with the increasing threat of drought. The province is highly vulnerable to climate change, and local agriculture—reliant mainly on rainfall—has suffered from recurring water shortages. In response, the Organic Farming Community Enterprise of Bua Yai Subdistrict launched a project to create sustainable agricultural water systems using solar-powered pumps, while also planning ecosystem restoration efforts.
Additionally, Thai Watsadu, part of Central Retail, collaborated with local administrative bodies in Chiang Khong Subdistrict, the forestry department, farmers, and other stakeholders to support the installation of solar-powered water distribution systems. The initiative also served as a platform for knowledge sharing on constructing water-retaining check dams, particularly cement-core soil dams.
In 2024, the project supplied 390 bags of cement approximately 19,500 kilograms—to build four such dams in the Huai Nam Cham area. As part of its commitment to innovation, Central Retail has invested 50,000 baht in R&D to improve water systems, enabling the community to expand crop production, including planting pumpkins for supply to Tops stores. This investment demonstrates Central Retail’s proactive approach to mitigating water-related risks while creating economic opportunities for local farmers.
Building on water security at the community level, Central Retail expanded the collaboration toward broader upstream ecosystem restoration. In 2025, Thai Watsadu, together with communities, government agencies, and network partners, supported construction materials and equipment worth more than THB 600,000 to jointly construct and restore 295 check dams, with participation from more than 300 people from agencies and communities. These check dams help slow water flow, increase moisture in soil and forest areas, and support the restoration of nature’s water-retention capacity, which is important for reducing communities’ long-term vulnerability to drought. The collaboration also reflects continuity in implementation. From 2017-2025, Thai Watsadu supported the construction of 1,425 check dams, with total support worth more than THB 2 million, benefiting more than 30,000 people in the area and demonstrating the power of collaboration among businesses, communities, and network partners in jointly restoring natural resources.
In 2026, Thai Watsadu and BnB home continued their upstream forest restoration mission for the sixth year by supporting construction materials and equipment worth more than THB 480,000 to construct and restore 400 check dams in Chiang Mai and Lamphun provinces. The initiative covered more than 3,000 rai of upstream areas and helped slow and retain approximately 1.2 million cubic meters of water, contributing to the mitigation of drought, flooding, and soil erosion while supporting water security for local communities. Over six years of implementation, Thai Watsadu and BnB home have jointly constructed and restored a total of 1,830 check dams, with support for construction materials and equipment worth more than THB 3.2 million, reflecting their commitment to expanding from addressing specific local challenges toward building long-term resilience for ecosystems and communities.
For Central Retail, sustainable water management does not mean only developing infrastructure; it also means strengthening communities so they can care for and manage their own resources while restoring the ecosystems that form the foundation of their livelihoods. Every check dam constructed, every piece of knowledge transferred, and every collaboration established is therefore part of creating shared value for people, communities, and the environment.
