All Day Riverviews
+ POOL is a plus-shaped, water-filtering, floating swimming pool, 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. + POOL strives to reclaim the river as a recreational resource for the city, while educating the public about issues affecting our water quality.
New York is an incredible place to live. You can do almost anything here. Anything, except swim in the river. Manhattan is an island — literally surrounded by water — but we haven’t been able to swim safely in the river for decades. It started with a simple idea: instead of trying to clean the entire river, what if you started by cleaning it piece by piece? And what if you could change how New Yorkers see their rivers, just by giving them a chance to swim in it? + POOL will clean more than 600,000 gallons of river water every single day. No chemicals, no chlorine, just natural river water.
When + POOL opens, it will be the first time New Yorkers have been able to swim directly in their river since 1938. That experience needs to be available for everybody. Following the footsteps of innovative public/private projects like The High Line, we created Friends of + POOL, a 501c3 non-profit, to ensure that it benefits the public in the best way possible.
Our nonprofit supports the development and eventual operation and maintenance of + POOL, but was also founded to support the preservation, restoration and conservation of natural bodies of water; promote water stewardship; and educate the public about the importance of clean water.
+ POOL is for everyone, which is why it’s designed as four pools in one: a Kid’s pool, Sports pool, Lap pool and Lounge pool. Each can be used independently to cater to all types of swimmers, combined to form an Olympic-length lap pool, or opened completely into a 9,000 square foot pool for play. Its universally recognizable shape and unusual offshore siting immediately position + POOL as an iconic piece of public infrastructure.
Like a giant strainer dropped in the river, + POOL filters river water within its walls, removing bacteria, contaminants and odors, leaving only safe, swimmable water that meets local and state standards.
We’ve worked with engineers at Arup to study the structure, mechanics, and filtration systems, and ecological consultants at One Nature to maximize + POOL’s benefit to the environment. We’ve spent six weeks on a pier in the East River testing different filtration materials and learned about enterococci and fecal coliform from professors at Columbia University’s Lamont-Doherty Earth Observatory. We’ve worked with innovation designers at IDEO and naval architects Persak & Wurmfeld to design + POOL’s floating structure. We tested the full filtration system in the harbor for five months and proved our filtration concept works. We filed a provisional patent. We studied the feasibility of various sites with marine engineers at McLaren Engineering throughout the harbor to understand what physical conditions are ideal for + POOL. And we gained the support of city and state agencies, open-water swimmers, waterfront advocacy organizations, and over 5,000 incredible supporters who pledged money through Kickstarter, events, and our nonprofit! + much more!
We’re currently working with the Mayor’s Office to identify a home for + POOL. This is an insane process and taking much longer than we ever would have thought, given there are many stakeholders involved in waterfront properties. If you haven’t yet, help us by telling the Mayor you want this for your city! Once we gain access to a site, we’ll be able to prepare site-specific design and construction documents, apply for permits, and start construction!
