Naturalistic walk: discovery of filter basins

Biodiversité

Do you know that the site of the filter basins is a work aimed at filtering the water from the outlet of the Grimonpont wastewater treatment plant? And that it constitutes a formidable reserve of biodiversity offering refuge to many animals like the elegant swan or the amusing green frog.
During this walk, you will be able to observe them but also learn about the journey of water!
