Global Initiative Aims to Transform Urban Waterways into Safe Swimming Areas

Swimmable Cities, a global alliance established in 2023, is working to restore polluted urban rivers to safe swimming standards. The coalition includes government officials, environmental experts, and advocates from 100 cities worldwide, with a goal of expanding to 300 by 2030. Recent developments include Chicago allowing public swimming in its river for the first time in approximately a century in September 2025, and Paris opening the Seine to swimmers in 2024 after extensive cleanup efforts. The movement addresses long-standing pollution from sewage and stormwater runoff, aiming to improve public health, ecosystems, and community engagement with urban waterways.
