Community funded NYC swimming pool aims to float in and filter river water

Hot on the heels of the Osaka canal swimming pool in Japan comes NYC-based + POOL, a Kickstarter project that started with a simple goal: instead of trying to clean the entire river, what if you started by just cleaning a small piece of it? And what if you could change how New Yorkers see their 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 to swim in clean river water for the first time in 100 years. 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. The pool will clean up to half a million gallons of river water every single day. In doing so, the pool will make a measurable contribution to the rivers of New York City.
