Volume of water used in the university: Inbound (treated/ extracted water)

1. Campus Water Consumption

In 2024, NCUE consumed a total of 499,186 m3 of water, comprising 153,517 m3 of tap water and 345,669 m3 of groundwater, respectively. Tap water and groundwater accounted for 30.75% and 69.25% of total water consumption, respectively as shown in Table 1.

(3) Total campus population: 9,950

2. Per capita water consumption:

(1) The average daily per capita water consumption of NCUE (both campuses) in 2024 was approximately 137 L. (499,186,000L /365 days/9,950 people=137L).

This was lower than the country’s average daily per capita water consumption of 289 L(data source: Water Resources Agency, Ministry of Economic Affairs website:
https://www.wra.gov.tw/News_Content.aspx?n=2868&s=6999 )

(2) Due to a series of major earthquakes in 2024 that caused increased pipeline leakage throughout the campus (as shown in Figures 2 and 3), NCUE's daily per capita water consumption showed a slight increase.

3. Smart Water Meter Installation and Enhanced Water Management

NCUE plans to install 7 ultrasonic smart water meters on the Jinde Campus and add 23 new ultrasonic smart water meters on the Baoshan Campus by the end of 2025 (schematic diagram shown in Figure 4). On the Baoshan Campus, each building will be equipped with groundwater and tap water meters to monitor water usage data for each building. The university can evaluate the water usage patterns by analyzing the water consumption and event data wirelessly transmitted from smart water meters. The flow trend charts automatically generated by the management system can be used to detect abnormal water usage. Real-time data obtained from smart water meters enables effective management of on-campus water usage and provides instant water resource monitoring information. By installing smart water meters across the campus, NCUE can consolidate various water resource data throughout the campus to serve as a basis for water resource balancing, allocation, leak detection, and management.
