Erren River
A historically impacted river spanning Tainan and Kaohsiung; recent remediation opens the door to a new ecological corridor and carefully staged public access.
Key Issues
- Legacy industrial pollutants in sediments in some reaches
- Stormwater-driven spikes in turbidity and bacteria
- Fragmented riverfront access and wayfinding
Targeted Actions
- Constructed wetlands and aeration cascades to polish water quality
- Targeted sediment management and shoreline habitat restoration
- Safe-entry pontoons and lifeguarded swim windows during best conditions
Pilot Swim + Access Sites
- Mid-reach park nodes with interpretive eco-corridor signage
- Downstream habitat terraces supporting fish and birdlife

Safety + Water Quality Protocol
Public swimming will proceed in phases, based on water quality thresholds and onsite supervision. Pilot swim windows open only when recent tests meet safety criteria (E. coli GM ≤ 500 CFU/100 mL; no heavy rain in last 48 hours; turbidity and visibility acceptable). Transparent weekly reporting and onsite signage will communicate conditions.
