A student from NC State University conducted a research study and chose Armory Pond in Raleigh as a test location. This location was one of three involved in the study. It was selected because of its excess of bioavailable nutrients and persistent algae blooms. Both of which promoted the growth of invasive plant species in the pond.

The goal of the study was to observe the efficacy of floating treatment wetlands. Specifically, the student wanted to determine how the strategic placement of Beemats at the inflows and outflows could improve the storage and removal of phosphorus and nitrogen within the body of water.


To assist the study, NC State student reached out to Ferguson Waterworks. Together, we installed a floating Beemat island around the outflow structure in order to target nutrients as they left the pond. After 365 days of monitoring the structure and water, valuable data was collected.

The floating island was successful in taking up excess nutrients. In conclusion, this placement helped reduce algae blooms.

Product Advantages

Beemats float on top of the water and work to remove both nitrogen and phosphorous. This is accomplished as a result of its unique design which involves the use of patented pots. Their versatile design allows for the harvesting of plant materials as well as the replacement of individual plants if necessary.

Key benefits of Beemats floating wetlands:

  • Sequesters excess bioavailable nutrients in the water column.
  • Competes with invasive species by vegetating it with native plants.
  • Available for both new construction and retrofits.
  • Periodic maintenance ensures the success of the project.
  • Includes reports showing the removed nutrients.
