Stakeholders Directly Impacted
Commitment and Target
Sikarin Public Company Limited recognizes that water is a fundamental resource for delivering quality, safe, and continuous healthcare services. Water is essential to medical treatment, hygiene control, the cleaning of equipment and operational areas, and the daily consumption needs of patients, patients’ relatives, employees, and visitors.
The Company is therefore committed to managing water responsibly, with a focus on efficient water use, reducing operational water loss, controlling water and wastewater quality in accordance with relevant requirements, and developing utility systems to support effective use while maintaining hospital service standards.
In 2025, the Company continued to use its target of reducing water consumption by 5% from the 2024 base year as a key framework for performance monitoring. At the same time, the Company advanced its water management approach from operational water-saving measures toward a broader stewardship approach that connects water management with risk, business continuity, and long-term environmental responsibility.
Challenges and Opportunities
Sikarin Public Company Limited places great importance on water resource management within the healthcare industry, where there is a high demand for water usage in activities such as medical equipment cleaning, dialysis services, and air quality control within hospital facilities. However, climate change and the degradation of natural water sources could threaten the security of clean water supply. As a proactive response, the Company has implemented measures to conserve and utilize water efficiently, aiming to mitigate risks associated with water quantity and quality. In addition, investments in water treatment technologies and water reuse initiatives, such as using treated water for landscape irrigation or facility cleaning, have enhanced the resilience of the hospital’s water systems, created added value for surrounding communities, reduced operational costs, and strengthened the Company's sustainable corporate image.
Management Approach and Value Creation
The Company integrates water management into its environmental management system and day-to-day hospital operations. This covers water consumption tracking, water and wastewater quality control, utility system management, maintenance of related systems, and communication to promote efficient water use across operational areas.
This approach enables the Company to better understand water consumption trends, identify areas for improvement, reduce unnecessary losses, and define water management measures that are appropriate for the hospital context without affecting hygiene standards, patient safety, or healthcare service quality.
Efficient Water Use
Efficient water use is one of the Company’s key priorities. The Company works to reduce water loss at source, inspect and control leakage in water supply systems, monitor water consumption regularly, and encourage employee participation in responsible water use.
In 2025, these measures supported the Company in achieving its target to reduce water consumption by 5% from the 2024 base year. Municipal water consumption decreased to 280,398 cubic meters, representing a reduction of 5.42%. This result was supported by organization-wide campaigns to promote efficient water use, together with a decrease in the number of patients receiving treatment compared with the previous year.
Wastewater and Effluent Quality Management
The Company places importance on appropriate wastewater and effluent management to prevent impacts on communities, the environment, and public hygiene. Its approach covers wastewater treatment system management, effluent quality monitoring, and the management of related systems in accordance with applicable laws and relevant standards.
For wastewater treatment system data used in the corporate carbon footprint assessment, the scope covers the wastewater treatment systems of Sikarin Hospital Bangkok and Sikarin Hospital Samut Prakan. Septic tank data covers Sikarin Hospital Bangkok, Sikarin Hospital Samut Prakan, and the Phaholyothin office. This defined data boundary supports clearer monitoring and environmental disclosure.
Water Crisis Management and Business Continuity
The Company recognizes that water-related risks for hospital operations are not limited to water use under normal conditions. They also include severe events that may materially affect the continuity of healthcare services, such as heavy rainfall, flash floods, delayed drainage, utility disruptions, and impacts on the quality or availability of water sources.
The Company therefore places importance on assessing the vulnerability of operational areas and utility systems that are critical to service delivery, including electricity systems, water supply systems, wastewater treatment systems, air-conditioning systems, medical supply storage areas, parking areas, and main hospital access points. This enables the Company to identify risk points and define appropriate prevention or mitigation measures.
This approach helps the Company maintain essential healthcare services, reduce risks to patient safety, and minimize service disruption during water-related incidents or climate-related disasters.
Data Tracking and Performance Disclosure
The Company believes that effective water management depends on data that is accurate, complete, and decision-useful. It therefore continuously monitors water consumption, water-related expenses, and relevant data boundaries to assess the effectiveness of implemented measures and to support future water management planning.
In addition, the Company’s municipal water consumption data is used as part of the corporate carbon footprint assessment within the relevant scope. This helps connect water management with environmental management and the Company’s sustainability disclosure in a more systematic manner.
Advancing Toward a Safe and Sustainable Future
Sikarin Public Company Limited plans to invest in technologies and systems that help minimize water loss, such as real-time leakage detection and immediate repair systems.
The Company will establish water-saving measures and promote the reuse of treated water for non-potable purposes. Furthermore, training programs and awareness campaigns will continue to encourage employee participation in water conservation initiatives, supporting long-term sustainability across all operations.
