Biologic Design


Biologic Design was established in 1993 with the aim of creating integrated, multi-species constructed wetlands for regenerative wastewater purification, biodiversity enhancement and resource production.

We are a family-run design company working with a wide range of clients and specialise in the creation of constructed wetlands, which we call Wetland Ecosystem Treatment or WET Systems.

We believe that WET Systems, developed by Biologic Design, are the most cost effective, energy efficient and sustainable wastewater purification systems available.

Our clients, be they in domestic, agricultural or industrial situations, are aware of the need to minimise or eliminate completely the energy used in purifying their effluent.

WET Systems are 'powered' by photosynthesis and so are able to massively reduce running costs because they do not require the non-renewable energy needed to run the more energy-intensive conventional wastewater treatment processes.

Not only do WET Systems reduce Carbon Dioxide emissions but also sequester this greenhouse gas as the plants and trees grow, creating biomass resources and soil within the system.

WET System designs have included:    

Domestic Sewage Systems from one person to 450 

Regenerative, Low-input and Organic Farmers

Food and Drinks producers

Sustainable Housing: One Planet, Off-Grid and Low-impact Developments

Ecologically-minded people and Organisations

Campsites, Glamping venues and Caravan parks

Ecological education and Permaculture Design projects

We design and create WET Systems which combine wastewater purification, resource production and enhanced biodiversity.

Many of the wetland plants, as well as the many varieties of bush willow which are used in the creation of our constructed wetlands, are produced organically in our own wetland nursery, which is on land registered with the Soil Association.

WET Systems are not simple Horizontal or Vertical Flow Reedbeds. Our WET Systems use soil as the purification medium, not gravel as do conventional Reedbed Treatment Systems.

Our constructed wetland designs combine low-energy wastewater purification with a productive abundant landscape, rich in wildlife...
