A grassroots movement called Swimmable Cities is working to transform polluted urban waterways into clean, swimmable rivers for public recreation, despite hundreds of billions of gallons of waste flooding U.S. rivers annually due to aging infrastructure and storm runoff.

Paris

Efforts are underway in several major cities to restore urban rivers to a state clean enough for public swimming. Initiatives in Chicago, Paris, and London are addressing decades of pollution caused by outdated infrastructure and storm runoff, which have led to large volumes of waste entering waterways.

Recent milestones include Chicago's first public river swim in nearly a century and the opening of the Seine River for swimming in Paris. London is also working towards making the River Thames swimmable within the next decade, signaling a broader trend towards reclaiming city rivers for recreation.

Are swimmable cities coming back?

Jumping into a city river might sound crazy, but one grassroots movement is aiming to change things by making urban rivers clean enough to swim in again. Hundreds of billions of gallons of waste flood U.S. waterways annually. Old infrastructure and storm runoff make it worse. But progress is happening. Chicago held its first public river swim in nearly 100 years. Paris opened the Seine River as well. And London is targeting the River Thames in the next decade. So can cities undo decades of damage? We shall see. But swimming in a river downtown might not be so crazy in the near future.
