+POOL: a water-filtering, floating pool for New York City

Sustainability problem: Water pollution and Civic engagement

Because of water pollution and health concerns, New Yokrers haven’t been able to swim directly in their rivers since 1938.

Technology solution: 

  • +POOL is an initiative to build a water-filtering, floating swimming pool designed to filter the water that it floats in through the walls of the pool, making it possible for New York City residents and visitors to swim in clean river water.
  • This projects aims to recover the river as a recreational space for the city, while educating the public about issues affecting water quality and contributing to clean it.
  • The pool will filter bacteria and contaminants using concentric layers of filtration materials in the walls of the pool, leaving clean and safe river water inside. With this mechanism, the pool will be able to filter over 600 thousand gallons of water per day.

Organizational stakeholders

  • New York City government
  • Department of Environmental Conservation
  • Local communities
  • NYC Parks

Implementation steps

  1. Rise funds through a public campaign and partnering with interested parties.
  2. Test the filtering technology in the river to prove the concept.
  3. Work with the city to create a public-private partnership to make the project a reality.
