Project Overview: What is +Pool?
The +Pool is a groundbreaking public swimming pool that floats atop the East River in Lower Manhattan, offering safe, clean, and chemical-free swimming directly in river water.
Unlike any other pool in the city, +Pool is designed to serve multiple user groups through its unique plus-sign shape, which includes separate areas for children, lounging, lap swimming, and water sports.
- Location: Anchored off Pier 35, Lower East Side, Manhattan
- Type: Floating public pool with four distinct zones
- Purpose: Filter East River water for recreation, reconnect city dwellers to their environment, and promote public health
- Capacity: Full-size design will feature 9,000 sq ft of pool area, capable of filtering up to 1,000,000 gallons of river water per day
The concept is simple but revolutionary: allow New Yorkers to swim in the river again—safely. By filtering river water through a multi-stage, chemical-free system, +Pool provides a new standard for urban swimming in natural waterways.
Origin Story and Concept
+Pool was conceived in 2010 by architect Dong-Ping Wong, designer Oana Stănescu, and creatives Archie Lee Coates IV and Jeffrey Franklin. Motivated by the question “Why can’t you swim in the river anymore?”, the founders set out to develop an urban pool that could both clean the river and offer a vibrant recreational hub.
The +Pool initiative reflects a broader urban trend: reimagining underutilized or polluted public spaces as dynamic, people-centric environments. For much of New York’s past, swimming in the East River was a common summertime pastime—until pollution and hygiene concerns rendered the water unsafe. +Pool aspires to recapture that lost connection—not just through engineering, but by making urban waterways accessible once again to everyone.
- 2010: +Pool project initiated with visionary architecture and community input
- 2015–2020: Prototypes tested off Pier 35, refining filtration technology
- 2024: Major state investment announced, and first full-scale test site planned at Pier 35
- 2025: Pilot vessel constructed and delivered to New York City; weekly water quality testing continues
- 2026: Planned installation of the prototype pool, pending health review and public opening
Engineering, Design, and Environmental Innovation
Shape and Modular Functionality
Distinct for its plus-shaped layout, +Pool can function as:
- Lounge Pool for casual swimmers and sunbathers
- Kids’ Pool with shallow water for families
- Lap Pool for serious swimmers
- Sports Pool for aquatic games and exercise
The pools can be operated independently or combined to create a single, grand swimming space. This adaptability maximizes flexibility for programming, events, and diverse community engagement.
Filtration Technology
The signature breakthrough of +Pool is its innovative approach to water filtration. The pool uses a proprietary, multi-layered system that cleans East River water without chemicals or additives. The process involves:
- Physical Strainers: Coarse and fine mesh remove debris and sediment
- Membrane Filters: Specialized layers block bacteria, microplastics, and other microscopic impurities
- UV Disinfection: Ultraviolet light sterilizes the filtered water, neutralizing any remaining microorganisms
This filtration is so effective that, at capacity, the full +Pool is designed to process up to 1,000,000 gallons of river water daily—rendering it clear, clean, and safe for recreational use. The entire system aims for zero chemical use, in contrast with traditional municipal or public pools.
Construction Phases
| Phase | Description |
|---|---|
| Pilot Vessel | 2,000 sq ft floating pool built as a proof-of-concept; constructed in Mississippi and transported to NYC, 2025–2026 |
| Installation & Evaluation | Pilot pool installed at Pier 35, summer 2026, for rigorous Department of Health evaluation and public testing |
| Full-Scale Pool | Pending successful trials and regulatory approvals, 9,000 sq ft full +Pool to be built and opened, estimated 2027 or beyond |
Each construction phase prioritizes safety, water quality, and user experience, with ongoing consultation from city, state, and environmental agencies.
Testing, Approval, and Construction Timeline
Water Quality Testing and Regulatory Review
Ensuring safe swimming is paramount. Before any public launch, +Pool must undergo extensive water quality testing, regulatory review, and health inspections:
- Weekly Water Quality Sampling: Friends of +Pool organization conducts weekly sampling at Pier 35, tracking bacterial and toxin levels, in coordination with the Interstate Environmental Commission
- Pilot Filtration Tests: In 2024 and 2025, prototypes filtered East River water on-site to demonstrate efficacy to health officials
- Department of Health Evaluation: The NYC Department of Health will observe, assess, and certify the pilot pool before approving public use
- Final Installation: If the pilot passes, the pool will be fully opened for community swimming, and plans for an expanded +Pool will commence
Key Milestones
- 2010–2020: Initial development, outreach, crowdfunding, and experimental systems
- 2024: State funding endorsed as part of the NY SWIMS initiative; test filtration at Pier 35
- 2025: Construction of pilot vessel in Mississippi, shipping to NYC shipyard
- 2026: Installation at Pier 35, Department of Health review
- 2027+: Anticipated public debut and, if successful, full-scale pool construction
This timeline underscores the project’s complexity and its collaborative nature, involving city, state, and nonprofit partners.
Community, Culture, and Urban Impact
+Pool goes far beyond mere recreation—it exemplifies how urban infrastructure can reconnect city dwellers with nature in an equitable and inspiring way.
Equity and Access
As a public facility, +Pool is designed for everyone: families, athletes, tourists, and residents alike. Unlike rooftop pools or private clubs, +Pool’s mission is inclusivity—making clean, safe swimming accessible to every New Yorker.
- Free and low-cost access for the general public
- Children’s swimming lessons and water safety programs
- Community events across all demographics, fostering cultural exchange and civic pride
Cultural and Environmental Significance
The project draws on the heritage of New York City’s outdoor public bathhouses of the early 20th century while also setting new standards in green infrastructure. By cleaning water without chemicals, the +Pool demonstrates that urban development and environmental responsibility can go hand in hand.
- Promotes environmental stewardship: Raises awareness about river health
- Showcases local innovation: Developed by NYC architects, artists, and engineers
- Supports public health: Encourages swimming and water safety for all ages
+Pool is funded through a hybrid of public investment and grassroots crowdfunding, demonstrating broad community support and government buy-in.
Future Prospects and Vision
Upon successful approval and launch, +Pool has the potential to inspire similar floating, river-filtering pools worldwide. Its ambitious vision could transform not only New York’s waterfront, but also reframe how cities utilize and celebrate their rivers.
- Educational hub: Demonstrates advances in water treatment, public health, and design
- Expandable model: Modular system could be replicated in other urban settings
- Public/private partnerships: Serves as a template for future infrastructure initiatives
Advocates hope that +Pool will rekindle New York’s historical relationship with its waterways, making swimming in the East River a safe, regular, and joyful city experience once again.
Frequently Asked Questions (FAQs)
What is +Pool and how is it different from other NYC pools?
+Pool is a floating, plus-shaped public swimming pool anchored in the East River. It filters river water into clean, safe swimming water without chemicals—the first of its kind in New York City.
Where will +Pool be located?
Its pilot will be installed off Pier 35 in Manhattan’s Lower East Side. Future phases may expand elsewhere in the city.
How does +Pool clean the river water?
+Pool uses a combination of strainers, layered membrane filters, and UV disinfection to remove contaminants, bacteria, and toxins from the East River water before anyone swims.
