First Floating Pool Prototype Nears Completion in New York’s East River

The first physical prototype of +Pool, a long‑envisioned floating pool designed to safely use filtered East River water, is nearing completion in Brooklyn. Images released this week show the rectangular pilot structure, named Pool 1, mounted on a barge with an integrated infiltration system that will clean river water as it flows into the swimming area.

The pilot is a scaled‑down, rectangular version of the original +Pool concept, which was conceived as a cross‑shaped, plus‑sign floating pool. The project has been in development for nearly a decade, backed by a coalition of designers, engineers and public advocates who see it as a way to bring safe, accessible swimming back to New York’s waterways.

How the filtration system works
The key technical innovation of +Pool is a multi‑stage filtration system built into the pool’s structure. River water is drawn in, passed through a series of screens and filters, and then circulated into the swimming area. The process is designed to remove bacteria, contaminants and microplastics, making the water meet federal and state recreational water quality standards without the need for chemical disinfectants.

The pilot barge in Brooklyn includes a full‑scale test of this filtration system, allowing engineers to monitor performance under real‑river conditions. The team behind +Pool has stated that the system will be continuously tested and adjusted before the full‑size cross‑shaped pool is built.

Key facts

Why this matters for urban design and public space
Floating pools are not a new idea, but +Pool is notable for its ambition to use a major urban waterway that has long been considered too polluted for swimming. If successful, the project could serve as a model for other cities with underutilized rivers and harbors, offering a way to create public recreation space without consuming valuable waterfront land.

The pilot also highlights the growing interest in infrastructure that adapts to climate change and rising sea levels. Floating structures that can operate independently of sewer systems and stormwater overflows are increasingly relevant for coastal cities.

Next steps and timeline
The pilot pool is expected to be fully assembled and begin water‑quality testing within the next few weeks. If the filtration system consistently meets safety standards, the team will proceed with fundraising and permitting for the full‑size +Pool, which could be deployed at a permanent location in the East River or another New York waterway.

The project has not yet announced a timeline for the full pool, nor has a final site been selected. Community input and regulatory approvals will be required before construction begins.
