Climate change and exponential economic growth have caused changes in water use patterns, and resulted in a greater risk of water shortages. ThaiBev has conducted a comprehensive water management analysis that looks at the entire value chain. ThaiBev encourages the development of innovations to maximize efficient water usage, and to control the quality of water discharged into surface water to meet quality standards. ThaiBev assesses the sustainability of water use to reduce the risks and impacts of water consumption for both the short and long term.
ThaiBev initiated the Water Sustainability Assessment (WSA) for both surface water and groundwater. The objective was to conduct an in-depth assessment of present and future water risks covering the following four areas:
1.	Water Availability
3.	Regulatory Changes
4.	Stakeholder Perceptions
Satellite imagery is used to study watershed topography, water flow direction, drainage, slope patterns, and trends of water usage during the past ten years.
A water footprint consists of consumption data for both direct and indirect water usage for production and services throughout the supply chain. Enabling the company to set water management policies to maximize the efficient use of water resources and attempts to reduce the risk of water shortages that can have a direct impact on its business.
