Paris is currently celebrating the recovery of the River Seine with a historic swim that marks a milestone in the cleaning and sanitation of urban rivers.
For the first time in over 100 years, the city’s residents in France were able to take a dip, thanks to the ambitious environmental project driven by local authorities.
It was part of the preparations for the Paris 2024 Olympic Games, and the stage was finally completed. This historic event symbolizes the success of a long-term environmental policy aimed at restoring one of the most emblematic urban rivers in Europe.
A century without swimming in the Seine River: a story of contamination and recovery
Swimming in the Seine River had been prohibited since 1923 due to high pollution levels. For decades, the river served as a recipient of untreated wastewater, which severely affected its biodiversity and turned it into an unhealthy watercourse.

However, in recent years, the local government and the French State invested over 1400 million euros in sanitation infrastructure, stormwater collectors, and treatment plants.
These works have allowed a significant improvement in water quality, eliminating pollutants and reducing the presence of dangerous bacteria.
Paris is committed to sustainability and reconnecting with water
The initiative aims not only to restore the ecological value of the Seine River, but also its social function.
The project includes the creation of urban beaches, recreational spaces, and safe access points to the river, where Parisians and tourists can swim and enjoy the natural environment in the heart of the city.
This progress is part of a broader environmental policy that includes the renaturalization of public spaces, the promotion of sustainable mobility, and the city’s adaptation to climate change.
2024 Olympic Games: what happened to the Seine River and why it was in the spotlight
The milestone of public swimming in the Seine River comes a year after the Paris 2024 Olympic Games, where the river will be the setting for events such as triathlon and open water swimming.

Authorities assured that the water conditions would meet the international sanitary standards required by the Olympic Committee.
Paris Mayor, Anne Hidalgo, even emphasized that the achievement “demonstrated that when there is political will and environmental commitment, it is possible to reconcile cities with their rivers”.
However, doubts persisted, and the river was the scene of controversies and criticisms even after several athletes fell ill after swimming.
A model for other cities worldwide
Now, the confirmation of the Seine River’s recovery emerges as a successful model for the restoration of urban rivers worldwide, especially in contexts where water pollution remains a serious issue.
