Water Resources Management
Chang Gung University continues to promote campus water conservation and water recycling. Through facility upgrades, smart monitoring, and reclaimed water applications, the University improves overall water-use efficiency and advances sustainable campus management.
Key Achievements
Our Approach
Water-Saving Facility Upgrades
Electronic faucets have been installed at washbasins in public restrooms across campus. When facilities are replaced, water-efficient toilets and faucets carrying water-saving labels are given priority to gradually reduce daily campus water consumption.
Reclaimed Water & Water Reuse
Rainwater and reverse-osmosis secondary water recovery systems have been established. Water recovered from raft foundations, infiltration ponds, and laboratories is reused for ecological ponds and landscape irrigation, improving campus water recycling performance.
Smart Monitoring
Since 2022, smart water meters have been installed in major campus buildings and water treatment facilities. Data are integrated into the central monitoring system to support water-use analysis and ongoing conservation reviews.
Water Resources Management Progress
Over the past three years, per capita water use at CGU decreased from 49.08 tons/person in 2022 to 42.17 tons/person in 2024, demonstrating clear progress in campus water conservation.
To further improve water-use efficiency and support energy conservation and carbon reduction, the University has established annual per capita water-use targets for 2025–2027, with a planned reduction of approximately 2–3% each year. The goal is to reduce water-use intensity to below 39 tons/person by 2027.
Domestic and laboratory wastewater is discharged to the Guishan Water Resources Recycling Center operated by the Taoyuan City Government for downstream treatment, reducing the risk of water pollution.
CGU also continues to develop rainwater and reverse-osmosis secondary water recovery systems. Recovered water is directed to ecological ponds for purification and regulation and is subsequently reused for landscape irrigation. Improvements to existing drainage systems also help reduce tap-water use and mitigate the risk of backflow during heavy rainfall.
Total Water Withdrawal & Per Capita Water Use
CGU monitors both total water withdrawal and per capita water use to evaluate water-use efficiency and guide future conservation measures.
| Year | Total Water Withdrawal | Per Capita Water Use |
|---|---|---|
| 2022 | 414,268 tons | 49.08 tons/person |
| 2023 | 373,238 tons | 43.89 tons/person |
| 2024 | 363,930 tons | 42.17 tons/person |
| 2027 Target | — | Below 39 tons/person |
Water Management Outcomes
