6.2.2 Water consumption per person
In 2025, the volume of water used in Srinakharinwirot University (SWU), sourced from treated and extracted water, was 909,429 cubic metres (m³). The campus population, which is the sum of the full-time equivalent (FTE) number of students and the FTE number of employees, was 37,739. Water consumption per person was therefore 24.10 m³ per person. Campus visitors, the summer school population and remote students or staff are not included in the campus population.
Volume of Water Used in the University: Inbound Treated and Extracted Water
The volume of water used covers all treated and extracted water used across both campuses in 2025: treated mains water at Prasarnmit Campus (307,904 m³) and surface water extracted from canals and treated at the University's own plant at Ongkharak Campus (601,525 m³). Water consumption data were provided by the Physical Development Division and the Sustainable Development Division, Office of the President, through the University's SDG Sustainability Dashboard (see SDG 6.2.1).

Calculation of Water Consumption per Person, 2025
Item | Figure |
|---|
Total water used (m³) | 909,429 |
Student FTE (persons) | 31,551 |
Employee FTE including outsourced staff (persons) | 6,188 |
Campus population (persons) | 37,739 |
Water consumption per person (m³/person) | 24.10 |
Water consumption per person = 909,429 m³ ÷ 37,739 persons = 24.10 m³ per person.
