"Paris's Olympic River Revamp Inspires London's Transformation"

Paris is implementing a massive engineering project called the Swimming Plan to clean up the Seine River in time for the 2024 Summer Olympics, where it will serve as the venue for Olympic triathlon and distance swimming events. The plan involves thousands of new underground pipes, tanks, and pumps designed to prevent damaging bacteria from flowing into the river, particularly during storms. The aim is to make the water clean enough for Olympians and, later, citizens, to swim in. The legacy of the Games will be giving locals access to some 20 swimming areas along the Seine and its upstream tributary, the Marne, by the summer of 2025.
