6.3.2 Preventing water system pollution
Srinakharinwirot University (SWU) provides free drinking water for students, staff and visitors. In 2025, free drinking water was available at 157 drinking water stations (drinking water dispensers, similar to drinking water fountains) across both campuses: 112 at Ongkharak Campus and 45 at Prasarnmit Campus. Each station is labelled “Free Drinking Water – LOVES SWU” so that users know the water is free of charge, and all stations are open to students, staff and visitors at no cost.
Free Drinking Water Stations on Both Campuses
At Ongkharak Campus, 112 filtered drinking water dispensers are installed at 26 locations, including all 11 student dormitories and their service buildings, academic and administrative buildings, the Central Library, the Student Club Building, the sports building and the Faculties of Nursing, Pharmaceutical Sciences and Physical Therapy. The location of every station is published on an online campus map.
At Prasarnmit Campus, the Faculty of Science has installed 30 hot–cold water dispensers with high-quality filtration systems in Buildings 10, 15 and 19. The University provides a further 15 dispensers at 7 points in central buildings: Building 14 (in front of the lifts on every floor from 1 to 8), the Professor Dr. Saroj Buasri Innovation Building (floor 1), the Learning Tower (Building 35, floor 2 hall) and Cafeterias 1 and 2 (floor 1).

Maintenance and Water Quality of Drinking Water Dispensers
The University contracts the regular maintenance of the dispensers. At the Faculty of Science, the quality of the drinking water from the dispensers is tested every month. At Ongkharak Campus, the dispensers are supplied with tap water from the University's water production plant, which is tested every week against the tap water quality standards of the Provincial Waterworks Authority (see SDG 6.5.4). Students and staff are encouraged to refill their own bottles to reduce single-use plastic, in line with the University's Green University policy. The photograph below shows a student refilling her own bottle at a filtered water dispenser of the Faculty of Science, Prasarnmit Campus.

Smart Water Dispensers with Seven-stage Filtration
As part of its commitment to SDG 6 (Clean Water and Sanitation), SWU has installed smart water dispensers that give students, staff and visitors clean, safe drinking water free of charge. Each dispenser purifies the water through seven filtration stages, shown by indicator lights on the front panel: PP10 and PP5 sediment filters, a carbon filter (CAR), a resin filter (RES), an ultrafiltration membrane (UF), a post-carbon filter (PCB) and ultraviolet (UV) sterilisation. The lights let users see that every stage is working each time they fill a bottle. An additional pre-filter housing is fitted on the inlet water line, and each unit has an automatic safety breaker. With several taps on each unit, many people can refill at the same time.
The University sees access to high-quality drinking water as part of looking after the health and well-being of its students. The SDG 6 Clean Water and Sanitation icon on the front of every dispenser shows that this free service is part of the University's work towards clean water and sanitation for all. The photographs below show a smart water dispenser with its seven filtration indicator lights and the SDG 6 icon, and a student refilling a bottle free of charge.
Free Drinking Water Beyond the Main Campuses
Free drinking water is also provided beyond the two main campuses. At the SWU Demonstration School, Somdet Ya Learning Community, in Mae Chaem District, Chiang Mai Province, a highland school of the University, a new drinking water system was completed in August 2025 with funding from the Director of the SWU Prasarnmit Demonstration School (Secondary). Students took part in designing, planning and building the system, including its water storage tanks, as an integrated learning project, and the system now supplies enough clean drinking water free of charge for all students every day. The project was reported on 22 August 2025.
