At first I thought this was a joke about how global warming is going to turn walkable cities into "swimmable cities".

The idea is awesome though, why do polluters have more rights to our waterways than human beings who have always used local water to swim and bathe.

Interesting! It's always been a grievance that none of Chicago's many public waterways are swimmable.

What a great idea. I live in the twin cities and love swimming in our urban lakes but they get shut down often with Algae and E. coli. Great initiate to swim more. I would love to swim in the Seine.

I’ve been dreaming about this for decades. One challenge is that cities can’t directly control upstream pollution on rivers, which is generally the most common form of accessible swimming area.

We need better governance structures for rivers and other systems where selfish actions by people can cause harm distant to where it originates.

I though this would be some kind of scifi future Venice type thing, and was pretty stoked. Even more exciting that it's a real project!

I surf and it's amazing just how many beaches aren't always safe to swim at, let alone city rivers and lakes. I think we forget how surreal it is how little lives in those waters.
