Rivers Reborn: Cities Dive Into Clean Waterways
23 Jun
Summary
- Urban rivers are transforming, becoming safe and accessible for swimming.
- Cities worldwide are reclaiming polluted waterways for public recreation.
- Cleanups and advocacy efforts revive rivers, enhancing quality of life.

Once deemed too polluted for human contact, urban rivers worldwide are experiencing a remarkable resurgence as vibrant public spaces for swimming. Cities like Portland, Oregon, exemplify this transformation, with the Willamette River now safe and welcoming for swimmers after significant cleanup initiatives.
This movement mirrors successes in European cities such as Copenhagen and Amsterdam, which invested heavily in water quality improvements and infrastructure. Paris is also set to reopen the Seine for swimming for the first time in a century, coinciding with the 2024 Olympics.
Key to this revival are dedicated advocacy groups and substantial infrastructure projects, such as Portland's $1.4 billion "Big Pipe" project. These efforts aim to overcome historical pollution and public apprehension, turning rivers into cherished "liquid public spaces."
Challenges persist, including addressing historic racial inequalities in waterfront access and navigating bureaucratic hurdles. However, initiatives like Swimmable Cities are fostering global cooperation to share resources and best practices for making urban waterways safe and accessible for all.
