What is + POOL?
An initiative to build the world's first water-filtering,
floating pool, right here in New York's rivers.
New York is an incredible place to live. You can do almost anything here. Anything, except swim in the river. Manhattan is surrounded by water, and but the water is too dirty to allow the 8 million people who live here to enjoy it.

It started with a simple goal: what if you started by cleaning it piece by piece? And what if you could change how New Yorkers see the rivers, just by giving them a chance to swim in it?

+ POOL is designed to filter the very river that it floats in through the walls of the pool, making it possible for New Yorkers and its visitors to swim in clean river water. The layered filtration system incrementally removes bacteria and contaminants to ensure nothing but clean, swimmable water that meets both city and state standards. No chemicals, no additives, just natural river water.

Like a giant strainer dropped into the river, + POOL is designed to clean up to half a million gallons of water every single day.
