In recent years, most of the new buildings planned at our university have incorporated rainwater harvesting systems. These systems typically involve the installation of rainwater storage tanks and collection basins in the underground raft foundation. The collected rainwater is used for irrigating landscape plants. Notable examples include:
- Lixian Hall with a rainwater storage tank of approximately 382 CBM.
- Zonghe Lecture Building with a rainwater storage tank of approximately 33.6 CBM.
- Tseng Jiang Hall with a rainwater storage tank of approximately 130 CBM.
- Chee-Chun Leung Cosmology Hall with a rainwater storage tank of approximately 252 CBM.
- MK Innovation Hall with a rainwater storage tank of approximately 6 CBM.
NTU also has existing buildings equipped with rainwater harvesting systems. For example, the Hydrotech Research Institute installed an integrated water harvesting system (IWHS) in 2021, which results in an annual water recovery of approximately 3,000 metric tons.
These rainwater harvesting systems contribute to sustainable water usage on our campus. This results in an annual water savings of approximately 5,000 metric tons.
