Wetland Ecosystem Treatment (WET) Systems

Our constructed wetland ecosystems are called WET Systems and they function by harnessing the innate ability of natural wetland ecosystems to absorb and transform the organic nutrients found in wastewater, converting these into plant biomass and soil.

WET Systems are an environmentally sustainable form of wastewater purification, they are low-entropy systems as they use no fossil fuels or electricity to purify the wastewater.

They are solar-powered, using the ability of plants to absorb solar energy during photosynthesis. The nutrients found in wastewater are mineralised by micro-organisms in the deep and dense root-zone, which enables the plants to absorb and use them as an input for growth.

WET Systems have a low-embedded energy, since, unlike conventional Reedbed Treatment Systems, no gravel or plastic aeration and distribution pipes are used in their construction.

Gravel does not need to be quarried and transported to site, and because plastics are not routinely used in our designs, WET Systems have a very low embedded energy or EMergy.

Soil in the root-zone not imported gravel, is the filtration medium and this is, in most cases, already on-site. Once established, the WET System functioning as a growing ecosystem starts to create topsoil...

Each WET System design is site-specific, and is based upon Permaculture Design Principles and good ecological practice.
