floating wetlands


New York City Department of Environmental Protection (DEP) is using floating, vegetated wetlands as wave attenuators in Jamaica Bay.

These floating treatment media are part of a pilot project which aim to protect the decreasing marsh shorelines. The 2-year pilot program will cost approximately half a million and was installed in September 2015.

In the 1800s, Jamaica Bay has 16,000 acres of green marshland but, due to pollution and rise in sea-level, only 800 to 1,000 acres of marsh remain today.

Marshes are among the most productive ecosystems on the planet. They filter nitrogen and phosphorus from the water; provide fish habitat; store carbon; and protect against storm surges.

SPEL floating wetlands are easy to install and maintain.

It is also effective in:

  • Reduction in Bio-chemical oxygen demand
  • Removal of TSS
  • Reduction in faecal coliforms
  • Reduction in phosphorus
  • pH stabilization
