The use of water-efficient appliances such as hand-washing taps, urinals, and sprinkler systems provides significant environmental and operational benefits in the context of UI GreenMetric sustainability assessment. These technologies are designed to minimize water consumption while maintaining functional performance in daily campus activities. Accordingly, water-efficient hand taps, often equipped with sensor or low-flow mechanisms, reduce unnecessary water discharge during handwashing, thereby significantly decreasing overall water demand in buildings. Similarly, water-saving urinals, such as waterless or low-flush systems, contribute to substantial reductions in freshwater use in restroom facilities while maintaining hygiene standards. In addition, efficient sprinkler systems optimize water distribution for landscape irrigation by controlling flow rate and timing, which prevents overwatering and reduces water loss through evaporation or runoff. Therefore, these appliances enhance the university’s water conservation efforts and support sustainable campus management. In terms of the UI GreenMetric World University Rankings, their implementation directly contributes to improved performance under the Water (WR) category by reducing potable water consumption, promoting efficient resource use, and strengthening the institution’s commitment to environmental sustainability. Respectively.

Sakon Nakhon Rajabhat University has implemented the use of water-efficient appliances across campus buildings to reduce water consumption and improve water-use efficiency. The university continuously upgrades sanitary fixtures and plumbing equipment with water-saving technologies as part of its sustainable water management program.
The water-efficient appliances currently installed on campus include dual-flush toilets, low-flow urinals, and water-saving faucets. These devices are designed to reduce water usage while maintaining user comfort and operational effectiveness.
Based on the campus inventory survey, the university has a total of 1,683 toilets, 324 urinals, and 719 faucets. Among these, 43 toilets, 262 urinals, and 44 faucets have been identified as water-efficient appliances. The overall proportion of water-efficient appliances on campus is 20.73%.
The implementation of water-efficient fixtures contributes to reducing potable water consumption, lowering operational costs, and supporting the university’s commitment to sustainable water resource management. The university continues to replace conventional fixtures with more efficient alternatives during renovation and maintenance activities to further improve water conservation performance.
