The water treatment plant is located on the edge of the built-up area of Perros-Guirec, within a rural setting which still shows a strong wooded countryside character.
The project to reassemble the space intends to stage the engineering facilities and their highly spectacular dimensions, as well as the reappearance of the clean treated water as it is returned to the natural stream running through the site. To that end, the stream is being returned to the open air and its path is being highlighted by the use of pink granite blockfield. The treated water reappears as a waterfall, also made of pink granite blockfield. The vicinity of the structures is highlighted by technical zones made of crushed pink granite, while the vast grassy expanses are managed as extensive prairies. An educational trail is being created for visitors. It will review the various phases in the water treatment process, and in so doing will include the various facilities. The site will remain enclosed, with the hedges and shrubs reassembled all around the plot. Inside the site, a few trees are there to accentuate the space, like the tall Monterey pine trees that one can also see on the nearby coast.
