6.2.1 Measure the total volume of water used in the university that is taken from mains supply, desalinated, or extracted from rivers, lakes, or aquifers.
Metric: Water consumption per person
Prince of Songkla University systematically measures and monitors water consumption through utility records, conventional water meters, and an online water-metering system.
In 2025, the University recorded a total water consumption of [TOTAL WATER USE] cubic metres.
At Hat Yai Campus, the University maintains an on-campus reservoir that plays an important role in campus water-resource management. The reservoir serves as a source of stored water for domestic use and as a reserve raw-water source for the University’s water-supply production system. The University has also constructed an additional reservoir with an overflow-weir system in the Thung Yai extension area to increase water-storage capacity and improve water management during periods of high rainfall.
Water Consumption Measurement and Monitoring
PSU uses both conventional and online water meters to measure water consumption within the University. The metering system provides measurable records of water use and supports systematic monitoring of campus water demand.
Water supplied through the mains system is also documented through water-utility billing records, providing additional evidence of water consumption from the external water supply.
Real-Time Online Water Monitoring
Because PSU has a large campus area and substantial water demand, the University has implemented an online water-metering system that enables responsible units to monitor water consumption in real time.
The online dashboard displays consumption data from individual monitoring points and enables facilities staff to compare water use over different reporting periods. The system also helps identify unusual increases in consumption that may indicate water leakage or other abnormalities.
Examples from the October and November 2025 monitoring periods demonstrate the continuous operation of PSU’s online water-monitoring system.
Through the online monitoring system, the University can:
monitor water consumption in real time;
review water use at individual metering points;
compare consumption across different periods;
identify abnormal consumption patterns;
detect potential water leakage;
reduce unnecessary water losses; and
support more efficient management of water resources and utility expenditure.
PSU Online Water Metering Dashboard, October and November 2025.
The online dashboard provides real-time water-consumption information from individual monitoring points and supports the detection of abnormal water use and potential leakage.
Supporting Evidence
PSU maintains multiple forms of evidence to support the measurement and monitoring of water use, including:
water-utility billing records;
conventional water-meter readings;
online water-meter records;
monthly online monitoring dashboards; and
records from University-managed water sources.
Together, these systems enable PSU to systematically measure and monitor water use and provide the data required for university-wide water-resource management, water-loss prevention, and water-efficiency planning.
