ThaiBev regularly conducts a Water Sustainability Assessment (WSA) to assess its dependencies on both surface water and groundwater resources at production facilities, in order to identify any potential impacts and risks associated with its business units.

This in-depth assessment covers four dimensions:

• Detailed water source assessment, including the availability and internal structure of water resources.
• The vulnerability of the watershed, considering both social and environmental factors.
• Water-related natural occurrences, such as droughts and floods, etc.; and
• The quality of water sources.

This assessment covers a period of five years to ensure there are sustainable water supplies to support the facilities’ operations. Processes in the study include: water quantity, water quality, rules and regulations related to water resources, and stakeholders’ perception.

WSA allows ThaiBev to create a comprehensive risk mitigation strategy and action plan that is appropriate for local conditions while addressing both long-term and short-term water-related risks.

In parallel, ThaiBev also utilizes its Water Risk Tool to assess annual operational risks across all production facilities, as illustrated by the 'ThaiBev Water Risk Dashboard. These risks are categorized into three main types: Physical Risk, concerning water quantity and quality; Regulatory Risk, relating to legal and compliance requirements; and Reputational Risk. The dashboard highlights the top 5 production sites with the highest risk scores in each category. Furthermore, the dashboard provides a summary of sites indicating high or medium physical, regulatory, or reputational risk. This tool enables the company to evaluate historical risks over the past three years and anticipate future scenarios, including potential changes in future water quantity and quality. In 2024, ThaiBev experienced no operational impacts from physical water-related business risks.

ThaiBev Water Risk Dashboard

Water Quantity
ThaiBev monitors water availability monthly by comparing data from the National Hydroinformatics Data Center with internal forecasts. Risk Coordinators review reports, assess risks, and implement mitigation measures. Significant risks are escalated to the Corporate Risk Management. Our water-related risks are continuously monitored and effectively managed.

Water Quality
Water supply and effluent quality are monitored daily according to ISO 9001 and ISO 14001 guidelines. ThaiBev plants near the Chao Phraya and Tha Chin Rivers closely monitor surface water during the dry season due to saltwater intrusion, often substituting groundwater, which increases costs. To address shortages, freshwater storage and groundwater wells are enhanced. Groundwater use is strictly regulated in critical zones. ThaiBev continuously monitors regulations and applies the 3Rs principle, adopts advanced technologies such as Reverse Osmosis, and reduces water consumption per unit of product.


ThaiBev’s production plants are members of the Federation of Thai Industries (FTI), which regularly provides updates on new regulations relevant to various industrial sectors. These updates are shared through the FTI website, email, and regular meetings.

Each production plant has established a working group responsible for monitoring and assessing compliance with applicable water-related laws and regulatory developments. This group reports any potential regulatory changes or newly issued laws to the Product Group’s Risk Coordinator. At the corporate level, the Product Group’s risk coordinators consolidate and review information received from all production sites. Any risks identified as material are brought up to the Corporate Risk Management Working Team for further action.


ThaiBev to employ third-party to conduct community perception surveys around its production sites, aiming to understand concerns on water availability and industry impacts. Each plant establishes a stakeholder engagement group to hold regular meetings with local leaders and authorities. Feedback and survey results are reviewed monthly and reported to the Product Group’s Risk Coordinators. Any material risks or potential conflicts are escalated to the Corporate Risk Management Working Team for further action, and there have been no water-related incidents that have impacted our operations.

The Surface Water and Groundwater Sustainability Assessment allows ThaiBev to create a comprehensive risk mitigation strategy and action plan that is appropriate for local conditions while addressing both long-term and short-term water-related risks.

ThaiBev has collaborated with the Hydro-Informatics Institute (HII) on the “Water Resource Management for Surrounding Communities” projects to assess the risks of floods and droughts in both short and long terms by using the HII’s Water Resource Information System for Sustainable Development. The initiative supports water resource management in local communities around our production facilities that are in High to Extremely High water-stressed areas, covering a radius of five kilometers around each facility. Through this project, ThaiBev will be able to operate its business while creating value for the communities that share the same water sources by devising a mitigation action plan for water-related risks within and outside its operations.
The study process is as follows:

• Study the general condition of the area, the watershed condition, and meteorological and hydrological data - including potential sources of water pollution - to assess the flooding and drought situation, including historical occurrences of such events.
• Study the impacts of climate change on flood and drought issues, including the indices and trends in extreme rainfall data for current and future conditions. Create a probability map for extreme rainfall in the catchment area and its associated watershed areas around the facility.

The study was first conducted at Beer Thai Brewery in Kamphaeng Phet Province. In 2024, ThaiBev expanded the project to include Thanapakdi Distillery in Chiang Mai Province, Simathurakij Distillery in Nakhon Sawan Province, and ThaiDrinks Non-Alcoholic Beverage Production Facility in Lampang Province, which are also in Extremely High water-stressed areas.

Simathurakij Distillery, Nakhon Sawan Province
The results showed that the study area is significantly more vulnerable to drought than to flooding. Approximately 63% of the area is classified as being at high drought risk, while only 8.85% is at high flood risk. Mueang Tak District in Tak Province has been identified as a critical area of concern for both hazards. Additionally, Khlong Lan and Mueang Kamphaeng Phet Districts in Kamphaeng Phet Province are particularly susceptible to drought conditions. Within a 5-kilometer radius of the Simathurakij Distillery, nearly 99% of the area is at high drought risk, primarily due to its location outside of the irrigation zone and the dominance of surrounding agricultural land. Nonetheless, the distillery has effectively managed its water resources through the development of storage ponds and the use of groundwater wells, which has helped to mitigate water shortages during the dry season. Conversely, flood risk in the vicinity of the facility is relatively low, owing to its strategic location within a well-managed irrigation area that reduces flood vulnerability.

The assessment of climate change impacts on flood and drought risks further reveals notable shifts in rainfall patterns across different future timeframes. In the near term (2023–2048), rainfall is projected to increase during the mid-to-late dry season and late rainy season, while declining during the early rainy season and in January. This may lead to more frequent but less severe droughts, alongside an increase in both the frequency and severity of floods. Mid-term projections (2049–2174) suggest a continuation of these trends, marked by heightened rainfall variability and more extreme weather events. In the far future (2175–2200), the changes are expected to be even more pronounced, with a further rise in drought frequency, although with reduced severity and duration, and a sustained increase in flood risk. Across all time horizons, areas at risk of flooding are expected to expand in both scope and intensity, while drought-prone areas may decrease in size and severity. These findings underscore the importance of adaptive water resource management and proactive disaster preparedness in building resilience against the escalating impacts of climate change.

ThaiDrinks Non-Alcoholic Beverage Production Facility, Lampang Province
The results showed that the study area is at low risk of flooding; only 8.85% of the area is classified as high flood risk, with Mueang Tak District in Tak Province identified as a key area that warrants close monitoring. Moderate and low flood risk zones account for 35.53% and 55.63% of the area, respectively. The low flood risk near the Production Facility and within a 5-kilometer radius can be attributed to its location within an irrigated area equipped with effective water management systems, which help mitigate potential flood impacts.

In terms of drought, the watershed is largely characterized by moderate risk, covering 40.84% of the area, while 31.05% is identified as high risk, particularly in districts within Lampang Province. Around the ThaiDrinks Non-Alcoholic Beverage Production Facility, the drought risk is predominantly low (51.67%) due to its advantageous position within an irrigation zone and the implementation of drought mitigation measures, such as the use of storage ponds and groundwater wells. These measures contribute to a reliable water supply, even during extended dry periods.

An analysis of climate change impacts across near-term (2023–2048), mid-term (2049–2072), and far-future (2073–2088) scenarios reveals a projected increase in rainfall on monthly, seasonal, and annual scales. Notable increases are expected during the late rainy season and mid-to-late dry season, while some reductions may occur in the early rainy season. Rainfall variability and uncertainty are anticipated to grow over time, particularly in the far-future period. Flood risk is expected to increase slightly, especially in areas already prone to very high risk, whereas drought risk is projected to remain stable or decrease slightly in both spatial extent and severity. These consistent trends underscore the importance of adaptive water resource and risk management strategies in response to evolving climatic conditions.

In 2025, ThaiBev will extend the program to cover other production sites that are located in high to extremely high water-stressed areas. We also install Automated Telemetry Stations in upstream forest areas, which can provide insightful data, such as water level and precipitation, and other information necessary for effective water and disaster management.

ThaiBev has received the Water Footprint of Product (WFP) Certification from the Water and Environment Institute for Sustainability (WEIS), a division of the Federation of Thai Industries, for its Crystal drinking water. This certification was achieved through a water use assessment aligned with the principles of Life Cycle Assessment (LCA) across all stages of the product lifecycle—including raw material acquisition, processing and manufacturing, distribution and transport, product use, and end-of-life disposal. The evaluation measures the amount of water consumed and polluted throughout the full production cycle from the supply chain to the end-user. A product water footprint also provides insight into the impact on freshwater resources. This certification provides valuable guidelines for managing the product’s water use and enhancing the efficiency of water resource utilization. Moreover, it helps identify opportunities to improve water efficiency and reduce impacts on upstream, midstream, and downstream water resources. ThaiBev has demonstrated its commitment to sustainable water management by thoroughly assessing its water use through the Water Footprint of Product (WFP) certification.
