Swimming pools in the East River? Manhattan Borough President Scott Stringer floated the idea in a video introduction to the Blueway, a project that would revitalize a stretch of the East River from the Brooklyn Bridge to Midtown East.

Dan Tainow, education director at the Lower East Side Ecology Center, explained the issue to local residents yesterday during a tour of the East River that doubled as a discussion of the Blueway project. Due to the age of New York City’s sewer system, he said, wastewater from household sinks, showers and toilets shares the same set of pipes as runoff from city streets.

Most of Lower Manhattan’s wastewater travels through this pipe system to the Newtown Creek plant in Greenpoint, Brooklyn, where it is cleaned, filtered and released into the East River.
