The treatment plant Plantins in Beynes (78) is at the heart of a remarkable site, bordered by an area of archaeological excavations in the south and agricultural land in the North. The landscaping of the future equipment was a priority expectations, given the sensitivity of the site and the desire to preserve the living environment of residents and the quality of its built heritage.
The landscape integration of the project was essential. Therefore, the architectural aims to create a dialogue with the surrounding countryside, respecting the biological balance in place, and integrating its architectural and landscaping the operations building.
• The design of the operations building is bioclimatic and eligible THPE.
• Use of recycled and sustainable eco-materials generating the least possible waste (wood frame structure, gabion walls, roofs and vegetated wall ...).
• Implementation of renewable energy (solar panels, Canadian well and VMC double flow).
• Creation of an innovative filter plant allows the processing and extraction of stale air from the WWTP.
• Sludge treatment on site phytopurification through macrophyte beds (4,000 m² treating 25,000 m3 of mud / year).
• An educational course for the general public was produced in the treatment plant, which allows to highlight eco exemplary of this building.

Sustainable Development
- the wood is certified PEFC or FSC,
- the gabion wall is filled with stone from local quarries,
- the hollow core of heavy road coating are recycled and recyclable tire
- the insulation is made of cellulose wadding, from recycled paper.
- recovery of calories from wastewater treatment by a heat pump water / water (COP 4, ie it consumes 1 kWh of electricity to produce 4 kWh of heating) for space heating.
- wells brine coupled with comfort ventilation, ensuring internal temperature stability.
- 2.5 m² of solar panels positioned south side, for the supply of a hot water tank of 400L.

bioclimatic filter Serre
The olfactory comfort is ensured by the implementation of an innovative biofilter plant for processing and extraction of stale air of technical rooms. The 35m biofilter treats 3500 m3 / h of exhaust air. It is located in an eco-designed greenhouse, which heats the adjoining meeting room in the winter and allows, for jealousy located at the top, a dissipation of excessive heat in summer. This biofilter planted with suitable species such as ferns or grasses, requires very little maintenance and maintenance, and reduces the interior temperature variations up to 40%.
This alternative solution for air treatment in the form of greenhouse contains a bioclimatic and energy aspect. The greenhouse as it is located in the building involved in the period winter heating of the meeting room that adjoins it. Glass walls located between the greenhouse and the boardroom for transmitting the stored calories in the greenhouse. During the summer, solar radiation does not penetrate inside the greenhouse. Planted greenhouse allows a filtration effective air in architecture involved in building heating and reduction of heating related consumption.
Reasons for participating in the competition(s)
La station des Plantins de Beynes se situe au coeur d’un site remarquable, bordé par une zone de fouillesarchéologiques au Sud, et des terrains agricoles au Nord. Le parti architectural vise à créer un dialogue avec
l’espace rural environnant, en respectant l’équilibre biologique en place, et en intégrant par son traitement
architectural et paysager le bâtiment d’exploitation. L'ensemble s'inscrit dans une démarche d'économie circulaire :
- La haute qualité environnementale a été intégrée au coeur du projet : la pluviométrie, les vents dominants, la courbe d’orientation du soleil et l’environnement.
- Utilisation d'éco-matériaux recyclables : ossature bois, plaques composées de gypse (Fermacell) en revêtement intérieur, murs gabions en revêtement extérieur, utilisation de bardage en aluminium et d’enduits à la chaux.
- Le bâtiment d'exploitation est conçu bioclimatique en ossature bois. Une serre bioclimatique à l'étage permet de chauffer la salle de réunion attenante.
- Les eaux pluviales sont acheminées vers un mur végétalisé vertical et une toiture végétalisée horizontale pour se diriger vers le milieu naturel : la Mauldre et le ru de Gally.
- L’aménagement paysager comprend un ancien bassin d’aération recyclé en zone humide, des lits plantés de roseaux de 4000 m2 filtrant l’ensemble des boues liquides (25 000m3/an) de la station d’épuration, et une attention particulière portée à la faune et à la flore : enherbage, prairie semée de fleurs des champs, aires de nidifications des oiseaux, espaces pour le développement des papillons, des libellules, réserve pour les batraciens et les canards.
- La gestion de l’énergie dans le bâtiment éco-conçu : éclairage de la station en basse consommation, puits canadien couplé à une VMC double flux, et panneaux solaires thermiques pour chauffer l'eau du ballon d'eau chaude sanitaire.
- La création d’une serre filtrante traitant 3500 m3/h d’air vicié, désodorisé et dépollué par les plantes, sans aucun réactif chimique.
- La démarche éducative et le parcours pédagogique initiés par la mairie de Beynes, pour sensibiliser le public et particulièrement les écoliers, au domaine de l'environnement au fil de l'eau.
L’économie sur le prix d’une eau filtrée de qualité résulte de tous ces paramètres pour la consommateur : 1,16€/m3 au lieu de 1,70 €/m3. Une économie de 85 000 euros HT/an est générée suite au traitement des boues par les plantes (roselière) in situ (absence de transport et stockage des boues traitées).
