Srinakharinwirot University (SWU) implements a comprehensive water-management system aligned with HURS SI 2.3 by systematically monitoring campus-wide water consumption and using these data to guide targeted reductions. The University promotes behavioural change through awareness campaigns and water-conscious practices across units, while also installing water-saving devices—including low-flow and sensor-based fixtures—throughout both campuses. Regular inspections and a formal online repair system enable timely detection and correction of leaks, strengthening infrastructure reliability. SWU also utilizes alternative water sources by reusing treated wastewater for non-potable purposes such as landscape irrigation, helping reduce demand for freshwater. In addition, the University provides free, safe drinking-water stations and water-related health promotion activities, supporting both sustainability and student–staff well-being. Together, these initiatives demonstrate an integrated and effective institutional approach to responsible water stewardship.
Monitoring water usage and establishing targeted reductions.
Srinakharinwirot University systematically monitors campus-wide tap water consumption through SDG 6.2.1 “Water consumption tracking”, which reports monthly and annual usage by campus (Ongkharak and Prasarnmit). These data are analysed to understand consumption patterns and are used as a basis for planning future water conservation measures and setting targeted reductions in overall and per-capita water use.

Promoting behavioral changes to conserve water.
SWU encourages students and staff to use water responsibly through awareness campaigns and unit-level water-saving measures. Reminder signs placed beside taps and in restrooms prompt users to turn taps off after use and to report leaks or damaged fixtures. At unit level, water-saving measures are put into practice through the Green Office programme. The Faculty of Social Business Administration has issued formal water-reduction measures for its staff and facilities. The Central Library's water-saving measures ask staff and visitors to report damaged fixtures promptly, use water-saving sanitary ware, water plants only at scheduled times, and help build awareness of water conservation among library users. Together, these measures embed water conservation in daily routines across the University.

Installing water-saving devices throughout the campus
To reduce unnecessary water consumption, SWU supports all departments in upgrading to water-efficient technologies as part of its water-conscious management approach. This includes the installation of sensor faucets, low-flow fixtures, and other water-saving sanitary ware in buildings across the campuses, particularly in high-use areas such as restrooms, dormitories, and public facilities. These device-level interventions work in tandem with awareness campaigns to ensure that water efficiency is embedded into the physical infrastructure as well as daily user practices.

Conducting regular analysis of infrastructure to identify and repair leaks
The University maintains a formal online repair and maintenance system, managed by the Sustainability Development Division, which covers building infrastructure including plumbing and sanitary systems. Through this system, staff and users can report problems such as pipe leaks or damaged water fixtures, track repair status, and provide feedback on maintenance quality. Regular inspection schedules for central buildings and staff housing, combined with this structured online reporting and response process, enable SWU to detect, repair, and follow up on water system issues efficiently, thereby minimising water loss and ensuring the integrity of its water infrastructure.

Utilizing alternative water sources like rainwater harvesting or on-site recycling fornon-potable uses (e.g., gardening, toilet flushing)
SWU implements water reuse and alternative water-source practices in line with its SDG 6 water management commitments. Treated wastewater is reused for non-potable purposes such as landscape irrigation on campus, reducing the demand for fresh tap water in gardening and green-area maintenance. In addition, the University has piloted on-site water recycling technologies in selected facilities to support sustainable water use in dormitory and agricultural contexts. These initiatives demonstrate a practical application of circular water use for non-potable needs, contributing to long-term conservation of the University's freshwater resources.

Water Reuse Policy
The policy follows the National Environmental Quality Promotion Act and the Ministry of Natural Resources and Environment standards on effluent discharge from buildings. Its main measures are as follows.
1) System restoration: defective or damaged on-site wastewater treatment systems in academic buildings, administrative offices and staff residences must be repaired so that they work at full capacity.
2) New and renovated buildings: any new construction or major renovation that needs budget must include a preliminary wastewater treatment system before discharging into the university’s central drainage, and the discharged water must meet the required standards.
3) Quality monitoring: the quality of wastewater from every unit and of the final treated effluent is monitored and controlled continuously.
4) Reuse of treated water: the university supports reusing treated wastewater for beneficial purposes on campus, such as landscape irrigation.
5) Research and innovation: the university supports research, development and new techniques in wastewater management.
These measures come from the university’s Announcement on the Policy on Wastewater Management Operations, issued under Sections 34 and 37 of the Srinakharinwirot University Act, which also supports the reuse of treated wastewater within the university premises (Figure 2).
Announcement date
The Water Reuse Policy was officially announced on 13 December 2024 (BE 2567), as stated at the end of the document. This date falls within the 2022–2026 period, and the policy remained in effect throughout 2025.

Srinakharinwirot University uses the Saen Saeb Canal as an alternative water source for non-potable purposes. Water is pumped from the canal and distributed through sprinkler systems to irrigate the University’s lawns and green spaces, in place of treated mains water. This practice reduces the use of tap water for landscape maintenance, keeps the University’s green areas healthy and ready for use by students, staff and visitors, and makes effective use of a natural water source adjacent to the campus, in line with the University’s commitment to sustainable water management.

Any other specialized healthy lifestyle support services offered (please specify)
Beyond technical water management, SWU also supports healthy lifestyles and well-being through its water-related services. The University provides free drinking-water dispensers in dormitories, canteens, and academic buildings, with regular maintenance and quality checks to ensure safe and adequate hydration for students and staff. By combining safe drinking-water access with education on the value of water and resource conservation, these initiatives simultaneously promote health, reduce plastic bottle waste, and reinforce responsible water usage as part of everyday campus life.
