Regarding technologies for sustainable water extraction from aquifers, lakes, and rivers, NCUE focuses on the storage and utilisation of rainwater and the use of abundant local underground aquifers to meet the water needs of our staff and students. We ensure that they are able to access and understand the concepts of sustainable development and water resources management, thereby facilitating the protection and restoration of water-related ecosystems.

1. Constructed a detention basin:
The artificial Bai-Sha Lake, with an area of approximately 9,000 m³, functions as a detention basin when it rains. It collects rainwater and absorbs water discharged from the sur-rounding buildings and green spaces. The collected water is then used in sprinkler irrigations for the lawns and flowerbeds on campus.

The above picture shows NCUE's  Bai-Sha Lake  is with cultural characteristics of the storage tank.

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 reutilisation of rainwater serves as an alternative and supplementary source of domestic water and a source of water storage for firefighting.

Rainwater detention basin: Rainwater is recycled for use in the sprinkler irrigation system

3. In 2021, NCUE consumed 98,661 m³ of tap water (19.9%) and 396,121 m³ of groundwater (80.1%), with a total water consumption of 494,782 m³.
