Biological Design

Biologic Design was established in 1993 with the aim of creating integrated, multi-species constructed wetlands for sustainable 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.

Because they are powered by photosynthesis, WET Systems massively reduce the running costs, due to the energy required by more energy-intensive conventional wastewater treatment processes and therefore the carbon dioxide created by these other processes.

Our clients include ecologically minded people and organisations, sustainable housing and low-impact developments, campsites and caravan parks, off-grid dwellings, low input/organic farmers, food and drinks producers, as well as environmental, educational and Permaculture projects.

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

Many of the plants, as well as the many varieties of willow tree 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.
