SDG 6.5.4 Sustainable water extraction on campus

For sustainable water extraction from aquifers, lakes, and rivers, NCUE focuses on storing and using rainwater and on drawing from the area’s abundant groundwater aquifers to meet the water needs of its faculty and students. NCUE aims to ensure that all faculty and students have access to water and understand the principles of sustainable water resource development and management, in order to protect and restore water-related ecosystems.

1. Constructed a detention basin:

NCUE’s artificial lake, Baisha Lake, covers about 9,000 m2 and serves as a detention basin that collects rainfall and runoff from the surrounding buildings and green spaces when it rains. The collected water is used to irrigate lawns and flower beds on campus (Figures 1–3).

2. Installed devices for a sustainable water circulation system:

The rainwater storage and water supply system involves the intercepting and storing of rainwater by tapping on the natural terrain or using artificial methods. The rainwater is then reused as miscellaneous domestic water after a simple purification treatment. The reutilization of rainwater serves as an alternative and supplementary source of domestic water and a source of water storage for firefighting (Figure 4).

3. In 2025, NCUE used a total of 483,653 m3 of water: 128,825 m3 of tap water (26.64%) and 354,828 m3 of groundwater (73.36%), as shown in Table 1.

Water consumption (2025)	Tap water (m3)	Groundwater (m3)	Total (m3)
Jinde Campus	51,081	289,819	340,900
Shida Campus	77,744	65,009	142,753
Entire University	128,825	354,828	483,653

4. Smart Water Meter Installation and Enhanced Water Management

By the end of 2025, NCUE had installed 7 ultrasonic smart water meters on Jinde Campus (15 meters in total) and 23 new ultrasonic smart water meters on Shida Campus. Also, every building on Shida Campus has its own groundwater and tap water meters to monitor its water use. NCUE analyzes the consumption and event data that the smart meters transmit wirelessly to assess water use, and the management system automatically plots flow trend charts that can be used to detect abnormal usage. Real-time data from the smart meters allow NCUE to manage campus water use effectively and monitor water resources. With smart meters installed across its campuses, NCUE consolidates all types of water resource data as a basis for water balancing, allocation, leak detection, and management.
