A Water oriented Living lab on the campus gets applied and fundamental research components with the main goal to reduce the surface area of the “regular” planted filters by making them more performing toward filtration with the involvement of an increased biodiversity. This demonstrator makes part of the LL implementation in the Interreg SUDOE Tr@nsnet Project. A cooperation between UT3 Direction du Patrimoine, SGE, UMR IRIT, UMR IMFT, U La Rochelle, PME Epurteck will lead to a bioinpired filter located next to IRIT to treat waste water of the A1 building. This biotech with enhanced biodiversity and soil metabolism for organic mater biodegradation, will increase the green area of the campus, will help at the air temperature regulation , and prevent of any smelt and musquitos for the neighbourhood. The earth worms (are ecological engineers that dig biostructure networks in the soil, that may largely influence the water parameters when flowing through this soil. The current tested research hypotheses is: « how does a burrow network buried in the macroporous substrates of soils influence the water infiltration capacities ? » This is run through the cooperation between research group in Physic “MacroPorous media and Biology” of UMR IMFT and the FERMAT X-ray tomography for images of 3D gallery networks of worms burrow, and modeling of water infiltration water flux in porous media; and the ecological team Bioref (Biodiversity, biological networks and Fluxes in aquatic and terrestrial ecosystems) of UMR Laboratory of Functional Ecology and Environment

Scientific goals

Create a demonstration of the biodiversity (earth worms) influence on the water infiltration in the planted filter.

Use the water oriented living lab connected with a serie of IoT sensors to explore further research hypotheses about organic mater degradation,  water and pollutant flow in this type of new filter generation.
