Harvesting

Harvesting of Reeds at the Seasons End

  • Significantly decreases biomass in beds
  • Partial removal of metals helps to lower metal levels in accumulated biosolids
    over time
  • Reeds have greatest affinity for zinc and copper
  • Nine to twelve inches of stalk is left to aid air transfer to rhizome and
    promotes drainage in winter
  • Harvested material is disposed of through burning, composting, landfilling,
    baling or chipping
  • Evacuating a residual from reed beds follows established protocols by Constructed Wetlands Group.
  • Disposal of residue can be used for covering solid waste at landfills, stabilize mine reclamation areas, or agricultural application.
  • Biosolids residue has been screened and composted for removal of vegetative matter
