Tertiary reed bed design

Tertiary Reed Bed

A tertiary reed bed is a form of extra treatment or Effluent Polishing for the Secondary Wastewater Effluent produced by a traditional or modern waste water/sewage treatment plant.

A Reed Bed may be advisable where a particularly stringent effluent quality is required or where effluent loss by evaporation and transpiration is required to protect a vulnerable watercourse or sensitive groundwater. Partial or Seasonal soakaways are a further option in this situation.

Construction of reed beds involves a gravel bed with reeds that need to be cut and maintained on a regular basis. Specific designs are prepared for each project and site.

Constructed Wetlands

Where large areas of suitable land are available ‘Constructed Wetlands’ become a further treatment option.

Designs include features such as ponds and lagoons with reeds and willows.

Effluent may be lost by evaporation, transpiration and soakage.

Specific designs are prepared for each project and site.
