Reedbed Installation

Reedbeds are an environmentally friendly, sustainable and effective natural system used primarily for treating wastewater and managing stormwater runoff. They employ wetland plants, typically common reed (Phragmites australis) and other local reeds and plants, to filter and clean water through natural processes.

Key Characteristics of Reedbeds:

  1. Structure:
    • Vegetation: Primarily reeds, which have extensive root systems.
    • Substrate: Usually gravel, sand, or soil that supports plant growth and provides habitat for microorganisms.
    • Water Flow: Water is introduced at one end of the bed and flows through it, either horizontally or vertically, allowing time for treatment.
  2. Function:
    • Filtration: Physical trapping of particles and sediments by the reeds and substrate.
    • Biological Treatment: Microorganisms on the roots and substrate break down organic matter and pollutants.
    • Nutrient Removal: Plants absorb nutrients like nitrogen and phosphorus, preventing eutrophication of downstream water bodies.
    • Pollutant Degradation: Breakdown of harmful chemicals and heavy metals through microbial activity and plant uptake.
  3. Types:
    • Horizontal Flow: Water flows horizontally through the bed. This type is effective for secondary and tertiary treatment.
    • Vertical Flow: Water is introduced at the surface and flows vertically through the substrate. This type offers higher oxygenation and is suitable for primary treatment.


  • Wastewater Treatment: Used in small communities, individual homes, or industries to treat domestic and industrial wastewater.
  • Stormwater Management: Helps in reducing runoff, preventing flooding, and removing pollutants from urban stormwater.
  • Habitat Creation: Provides a habitat for wildlife, promoting biodiversity.
  • Aesthetic and Recreational Benefits: Can be integrated into landscapes, offering visual appeal and recreational opportunities.

Advantages & Disadvantages

  • Sustainable: Utilises natural processes, requiring minimal energy input.
  • Low Maintenance: Once established, they require little upkeep compared to conventional treatment systems.
  • Cost-Effective: Lower operational costs due to reduced need for chemicals and mechanical processes.
  • Environmentally Friendly: Enhances biodiversity and can improve local microclimates.
  • Space Requirements: Reedbeds require significant land area, which may not be feasible in densely populated areas.
  • Seasonal Variability: In colder climates the performance of reedbeds can vary where plant activity may slow down due to┬áseasonal changes however in the UK this is not much of an issue, we just like to be fully transparent.
  • Initial Setup Costs: Again, for full transparency, while operational costs are low once reedbeds have been dug and installed, the initial construction can be expensive. In the long run they pay for themselves so it’s a matter of what works for you.

Reedbeds offer an environmentally friendly, sustainable solution for wastewater treatment and stormwater management. By mimicking natural wetlands, they provide effective filtration and pollutant removal, enhance local biodiversity and contribute to a healthier environment.
