The Ministry of Environment (MOENV) has selected 11 key rivers, including Tamsui River, Laochieh River, Er Ren River, Jisui River, Yanshui River, Beigang River, Nankan River, Sinhuwei River, Zhuoshui River, Agongdian River and Love River for accelerated remediation and improvement of water quality in the river basins.

Through practical measures such as strengthening source reduction and on-site treatment of intercepted sewage, the MOENV has significantly reduced the severe pollution ratio of the main 50 rivers in our country from 14% in 2002 to 3.3% in 2023. Overall, the water quality of the rivers has been noticeably improved.

Persisting in efforts to improve river water quality, MOENV continues to monitor pollution sources and proactively collaborates with relevant enterprises and authorities to promote improvement measures and reduce river pollution. MOENV selects moderately or severely polluted water bodies, including those with excessive heavy metals (rivers and various water intake points), as priority targets for remediation measures:

1. Total volume control
2. Promoting on-site treatment facilities
3. Strengthening inspection and regulation
4. Utilizing livestock excrements resource
5. Accelerating sewage system projects (including wastewater interception)
6. Conducting in-depth inspections and functional evaluations of industries
7. Removing floating garbage from the river surface
