The two AMATA City Industrial Estates are in the eastern region, which is a water-stressed area. Thus, the continuously increasing demand for industrial water due to the expansion of the industrial sector with the development of the Eastern Economic Corridor (EEC) project, the rapid increase in the population in the area, and climate change is resulting in a water crisis. All these pose risks and challenges to the Company’s water management and may cause significant negative impacts on the Company’s key stakeholders in terms of business operations, environment, hygiene, and quality of life, as well as problems with access to water and competition for water in the area if it is poorly managed. Therefore, water and effluent are always two of the most important material topics that have been focused on by the Company and its stakeholders from the beginning.
Moreover, ineffective wastewater management or the inability to control the effluent discharged by the factories will increase the risk of effluent leakage out of the industrial estates. This not only impacts the environment, community health, and surrounding communities, but it also has a significant impact on stakeholder trust in the Company.
By adopting a circular economy approach and implementing innovations in water management for the industrial estates, the Company can reduce operating costs and ensure water security for both the users within the industrial estate and the surrounding communities, which rely on natural water sources. This is a key factor in building trust among stakeholders and investors and enhancing the Company’s competitiveness in the industry.
The Company strictly complies with relevant laws under the Industrial Estate Authority of Thailand Act (B.E. 2522, 1979), the Factory Act (B.E. 2535, 1992), and ISO 14001:2015 environmental standards. Water quality is regularly monitored by laboratories registered with the Department of Industrial Works, and the operating results on water and wastewater management are disclosed in the Environmental Impact Assessment (EIA) reports. The EIA Monitoring Report is regularly presented to the Environmental Quality Audit Committees of both AMATA Industrial Estates every six months. Business operators in the industrial estates are also supervised to ensure their compliance with the regulations of the Industrial Estate Authority of Thailand to prevent and mitigate the social and environmental impacts.
Since its inception, the Company has planned for the sustainable use of natural resources by utilizing surface water resources as efficiently as possible and establishing the corporate goals in wastewater management not to discharge effluent outside of industrial estates, in accordance with the Zero Discharge principle. This includes regularly measuring the water quality of the raw water sources used for the factories and wastewater at various points, as well as supervising and ensuring that the water quality indicators do not exceed the legal standards, or better, that they do not affect stakeholders in the short and long term.
In addition, the Company encourages the communities surrounding the industrial estates to have a better understanding of the Company’s business operations and sustainable water management. Also, the Company provides the expertise to help improve the water management of the community by integrating the cooperation amongst the Company, government agencies, and communities.
Both AMATA Industrial Estates are in the eastern region, which is a water-stressed area. The Company has conducted a drought impact assessment in the areas surrounding AMATA Industrial Estates and found that AMATA City Chonburi Industrial Estate’s main risk is raw water reserves within the industrial estate. The Company has therefore provided a backup source of raw water both inside and outside the industrial estate and maximized the reuse of treated wastewater to reduce water dependence on raw water from natural sources.
AMATA City Rayong Industrial Estate is upstream of the catchment area; the main risks are the integrity of watershed conservation and the confidence of surrounding communities in the ability to reserve and share the water supply. The Company has expanded raw water reservoirs within the industrial estate and secured a water reserve from outside while implementing the riverside and watershed forest conservation project and developing a water supply system to support communities in the event of droughts, etc.
The Company has set an industrial water supply policy and targets that there must be raw water reserves from various sources that are not less than 150% of the total consumption demand in AMATA Industrial Estates per year. In 2022, the demand for raw water in AMATA Industrial Estates was 52.17 million cubic meters. The Company has reserved raw water in 17 reservoirs with a total capacity of 66.6 million cubic meters in both AMATA Industrial Estates and provided a reserve water source outside the AMATA Industrial Estates, allowing the Company to meet more than 150% of total water demand within AMATA Industrial Estates throughout the year. As a result, the Company has never experienced a water supply shortage in AMATA Industrial Estates in the past 30 years.
