The Company strictly complies with relevant laws under the Industrial Estate Authority of Thailand Act, B.E.2522 (1979), 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 6 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 problems and mitigate the social and environmental impacts.
The Company has planned the sustainable natural resources consumption by using water resources with the highest efficiency and set the Company’s goal of wastewater management not to discharge wastewater outside the industrial estates, or “Zero Discharge”, since the commencement of business and to regularly monitor quality of water sources used as raw water in the industry and wastewater to ensure that the Company’s water management is efficient and does not affect the stakeholders both in a short and long run
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 to work together.
Both AMATA Industrial Estates are located in the eastern region which is drought prone area with water stress . A drought impact assessment conducted by the Company found that both industrial estates have different drought impacts. AMATA City Chonburi Industrial Estate is located at the downstream of catchment area before flowing into the Gulf of Thailand, posing a risk of insufficient water reserve in the industrial estate. The Company has had water management plan in order to efficiently manage inside and outside water reservoirs and maximize recycled water utilization.
AMATA City Rayong Industrial Estate where is located at the upstream of catchment area has risks in water management relating to watershed conservation and the confidence of surrounding communities in the Company's ability to reserve water supply. The Company has built reservoirs within the industrial estate and secured water reserve from outside suppliers while implementing the riverside and watershed forest conservation project and developing a water supply system to support communities in the event of droughts.
The Company has set a policy and targets that the volume of raw water stored in the reservoirs inside and outside the industrial estates must not be less than 150 percent of the total demand of industrial estates in order to respond to unpredictably changing climates at present. As a result, the Company has never experienced a water supply shortage in AMATA Industrial Estates in the past 30 years.
In 2021, the demand for raw water in AMATA Industrial Estates was 31 million cubic meters per year. the Company has 19 reservoirs in both AMATA Industrial Estates, with a total storage capacity of 61.4 million cubic meters and secures water supply from suppliers. This meant that the volume of stored surface water was more than 150 percent of the total water demand in AMATA Industrial Estates per year.
