French officials have unveiled a monumental water storage basin aimed at revitalizing the River Seine, slated to host marathon swimming events at the Paris Games and the swimming leg of the Olympic and Paralympic triathlons. Sports minister Amélie Oudéa-Castéra applauded Paris for its commitment to providing athletes worldwide with an exceptional venue on the Seine for their competitions.
Last year’s cancellation of swimming test events due to poor water quality highlighted the urgency of addressing the issue. Heavy rains overwhelmed the city’s antiquated sewers, resulting in a hazardous mixture of rainwater and untreated sewage flowing into the Seine, failing to meet safety standards.

The newly inaugurated reservoir, adjacent to Paris’ Austerlitz train station, is designed to capture surplus rainwater and prevent contaminated wastewater from entering the Seine. With a capacity equal to 20 Olympic swimming pools, this basin will now ensure that dirty water is treated rather than discharged untreated into the river.
Paris Mayor Anne Hidalgo pledged to personally swim in the Seine before the Olympics, possibly accompanied by President Emmanuel Macron. The basin’s opening marks a significant stride in river restoration, complementing other recent infrastructure developments such as a water treatment facility in Champigny-sur-Marne, east of Paris, inaugurated last month. During the Olympics, daily water testing at 3 a.m. will determine if events proceed as scheduled. In case of substandard results, events could face brief delays.
The cleanup initiative, totaling $1.5 billion in expenses covered by the state and local authorities, underscores a decade-long commitment to improving the Seine’s water quality and restoring its biodiversity. With these measures in place, Paris is poised to deliver an environmentally sustainable and safe aquatic venue for the upcoming Olympic Games.
