The Company regularly inspects the building and surrounding areas for potential water leakage and conducts routine maintenance to ensure that water supply systems and equipment within the premises remain in optimal condition. Automatic faucets have been installed in restrooms to minimize unnecessary water loss. Furthermore, the Company actively promotes water conservation awareness among employees across all AMATA offices through the “ALL SAVE ALL WIN” initiative. This campaign communicates responsible water use through signage and internal email communications, encouraging employees to avoid leaving water taps running during cleaning activities and to maximize water usage efficiency. For instance, melted ice water is reused for office cleaning and for rinsing food-contaminated packaging waste prior to drying and proper disposal.

In addition, the Company has implemented measures to reduce water consumption in common areas by utilizing treated or recycled water from the industrial estates for irrigation purposes. This recycled water is supplied through an automatic sprinkler system installed along the estate’s main roads and is also used by water trucks to irrigate other green spaces within common areas. To further enhance water efficiency, irrigation schedules are adjusted according to seasonal conditions. During the dry season, irrigation is carried out once or twice daily as part of routine operations. In the rainy season, the frequency is reduced—for example, irrigation is suspended on rainy days—to ensure the efficient and responsible use of water resources in maintaining green areas.

In 2024, the Company’s total water consumption amounted to 38.01 million cubic meters, with a water intensity of 1,128.81 cubic meters per rai or 7,055.05 cubic meters per hectare. Despite implementing various water efficiency measures, reducing water consumption, and increasing the use of recycled water, the water usage intensity per unit of operational area increased by 1.9% compared to 2023. This increase was due to the expansion of production capacity by certain factory operators, such as beverage manufacturing plants, as well as increased water consumption from new factory construction.

The Company places strong emphasis on efficient and sustainable water management through multi-stakeholder participation, with a particular focus on water usage by factory operators within AMATA Industrial Estates. In this regard, the Company has undertaken collaborative initiatives with factories in two key forms. First, it issues formal requests encouraging factories to use water efficiently and responsibly, reduce consumption and minimize water loss within their operations. These efforts support the Company’s sustainable water management measures and help mitigate the risks and potential impacts of future droughts. Additionally, the Company offers consultation support on recycled water systems through its team of water management specialists. This guidance assists factories in reducing wastewater management costs, ensuring compliance with water quality standards, and avoiding additional wastewater treatment charges as announced by AMATA Industrial Estate. These initiatives promote water conservation and encourage the reuse of treated wastewater for further beneficial purposes.

Further to this, the Company aims to encourage the factory operators in industrial estates, government agencies, and communities surrounding the industrial estates to have knowledge and understanding of the Company’s operations and sustainable water management guidelines. Additionally, it seeks to promote awareness of the potential impact on stakeholders and the environment that may result from inefficient water management practices. The Company has established a Water Management Learning Center in AMATA City Chonburi Industrial Estate since 2009 to share knowledge and insights from its water management practices, make it available to surrounding communities and the public to study the industrial estate's water management model, and raise awareness of visitors and their cooperation in water resource preservation.

Since its establishment in 2009, the Water Management Learning Center at AMATA City Chonburi Industrial Estate has welcomed 446 visiting groups, totaling 13,420 visitors. The Company aims to foster greater understanding of its sustainable water management practices among key stakeholders, including customers and local communities. The Learning Center is open to the general public, and organizations interested in visiting may submit a request to AMATA U Company Limited or AMATA Corporation Public Company Limited. In 2024 alone, the center received 1,114 visitors across 39 groups—comprising 10 general interest groups, 17 student groups, and 12 groups from central and local government agencies.

In addition, the Company leverages its knowledge base to support the development of public water source management in community areas adjacent to AMATA Industrial Estates. This is achieved through integrating collaboration between the Company, government agencies, and communities in reducing and preventing the discharge of wastewater and waste from the community into the public water system, maintaining the quality of the water system, and improving the environment of the communities.
