The entire Aubevoye wastewater treatment plant responds to an innovative HQE® approach, proposing a bioclimatic wooden frame construction building, combined with natural and high-performance materials that enable healthy, comfortable and sustainable construction, with positive energy through an integrated photovoltaic roof at the heart of a remarkable site. The building is oriented on a north-south axis allowing to benefit from an optimal sunshine during the period of the winter and during the summer the heat is dissipated by the ventilation double flux and the devices in roof of brise-soleil. The whole building is part of a green setting. Landscaping is offered through different landscape units that make up an eco-landscape throughout the site, supporting a walkway integrated into the educational pathway and promoting the development of biodiversity.

Sustainable Development

    The development of the Aubevoye wastewater treatment plant was designed to accommodate the public, particularly those with reduced mobility. All outdoor facilities are punctuated by educational and didactic panels for children and adults that raise public awareness of the preservation of water resources and discovery of biodiversity. Due to the faunistic and floristic richness, the Aubevoye wastewater treatment plant presents no visual nuisance to the near and distant environment. On the contrary, it encourages local residents to go there and increase their knowledge of the water cycle and its treatment and thus, it contributes to positive changes in the gaze and the relationship of these with their environment and their environment. life.

    • Bioclimatic building oriented on a North-South axis
    • Natural light thanks to the south-facing bay windows
    • Interior comfort: implementation of a Canadian well coupled with a dual flow VMC for cooling and maintaining a pleasant and stable temperature all year round.
    • Visual comfort on landscaped and aquatic outdoor spaces.

    The commune of commune Eure Madrie Seine wanted to set up green jobs by inserting young people in formation for the maintenance and the maintenance of the green spaces of the purification station.

    Treatment with artificial aquatic ecosystems favors a rich and varied fauna and flora stand. They contribute to the development of biodiversity. They are designed to ensure a true renewal of the natural heritage of various populations (insects, birds, amphibians ...) and more voluntarily. The principle is to consciously nest several types of environments:

    • Water points of different depths depending on the species
    • Several types of soil: sand, gravel ...
    • Different materials: wood, pebbles, rocks ...
    • Different strata of plants: tree, shrub, herbaceous
    • Different plant alliances.

    Reconstituted wetlands combine the effectiveness of ecological treatment with the conservation of fauna and flora adapted to this environment. These habitats can sometimes shelter endangered species (treefrogs, newts, dykes ...). Many species of birds and butterflies are attracted to the plant species of trees, shrubs and wetland plants on the outskirts of the resort.

    All of the landscaping makes it possible to be part of a sustainable development approach. Indeed, all developments are sustainable, requiring very little maintenance and are destined to continue to develop because they are perfectly in harmony with their environment. The Aubevoye wastewater treatment plant project, designed following the HQE® process, propose rustic meadows designed / integrated according to the different surfaces planned on the ground plane. They represent the ecological link between the surroundings and the installation of the resort. In addition, the various facilities contribute to the restoration of biodiversity on the site. This ensures the durability of the facilities.

The Aubevoye wastewater treatment plant project, designed following the HQE® process, propose rustic meadows designed / integrated according to the different surfaces planned on the ground plane. The species of meadows planted on the site represent the ecological link between the surroundings and the installation of the station, they have been chosen for:

    • Their ecological interest: their presence is one of the ways to save many animal species and restore them on the site. Indeed, a flower meadow is a particularly popular environment for butterflies and birds.
    • Their sustainability: The flowering meadows are open environments composed of grasses and flowering plants. A flowering meadow can present flowers from spring to autumn. Depending on the types of mixes chosen, the blooms spread out over a broad period of the year thus allowing the changing seasons to have a changing space with varied colors. This one will be composed of different seedlings, in order to obtain a rendering according to different colored hues: red, blue, yellow, rustic. The composition of the flowery mixture (example: poppy, flax, bidens, blueberry ...) will be associated with a sowing of grasses (red fescue and ryegrass), in order to ensure a good coverage all year long.
    •  Their low maintenance: Only two mows are needed in the year: one as early as possible in the spring, as soon as the grass begins to grow, and the other in autumn. The flowery meadow requires little maintenance, and no watering (except during sowing).

Testimony / Feedback

    Catherine MEULIEN, president of the CCEMS (Community of Communes Eure-Madrie-Seine) certifies that the treatment plant of Aubevoye fits into the heart of a site with a rich natural environment , bordered by agricultural areas to the south and west, by a ru in the east, and by the railway Paris-Rouen then the Seine to the northeast, with for main objectives: zero visual, olfactory and auditory nuisance and the restoration of biodiversity on the site, in particular by wetlands.

    Within the treatment plant, a bioclimatic building is constructed in timber framing isolated by cellulose wadding designed according to the HQE® approach. It includes a roof terrace of photovoltaic panels, as well as an external biofilter of treatment of the air by the plants of 27,50 m ². The sustainable management of stormwater from roads and roofs is managed by the implementation of filter basins and vegetated valleys allowing their infiltration to the plot.

    Thematic gardens create a coherent and diversified green outdoor area: green setting, aquatic basin, vegetated valley, orchard, stratum and shrubby hedgerows, flowering meadows.

    The station has also been designed to accommodate the public including a meeting room accessible by an elevator, and access from the floor to a merlon lined with aromatic plants, which allows to visualize all outdoor developments punctuated by educational and didactic panels.

    The Community of Communes Eure-Madrie-Seine has a low-impact green plant ecological in a natural site to protect that gives him complete satisfaction.


    The CCEMS has in the framework of its project to rehabilitate the Aubevoye wastewater treatment plant (new commune of Val d'Hazey) - doubling its treatment capacity - sought to create synergy and integration of several projects in its environment. This project is part of the goals and achievements of the 2018 National Landscape Award and would reward our community's strong commitment to sustainable development.

    The Community of Communes Eure Madrie Seine and its architect AR Architects are therefore jointly applying. Three simultaneous projects: the rehabilitation of the wastewater treatment plant and the search for a suitable mud sector, the rehabilitation and creation of an outdoor pond on its Aquaval Aquatic Center, the abandonment of two boreholes for water supply drinking water in the town of Gaillon (removal of perimeters of protection) near the aquatic center.

    A shared ambition: innovative energy choices, landscape integration in a respected environment, a quality of life, sustainable projects that are efficient in operation. The territorial project formalized in 2017 reinforced this strategy in the longer term. The Project of Development and Sustainable Development of the Local Plan of Intercommunal Urban Planning worth SCoT sets objectives directly in continuity of this political project.

    Beyond the efficiency of the wastewater treatment system, the public order concerning the project management team for the wastewater treatment plant had several ambitions:

    • Integrate the Aubevoye wastewater treatment plant at the heart of a site with a rich natural environment, bordered by agricultural areas to the south and west, by a ru in the east, and by the ParisRouen railway then the Seine to the Northeast,
    • Green spaces integrated into the landscape and respectful of the environment: thematic gardens allow to create a coherent and diversified vegetated outdoor space: green setting, aquatic basin, vegetalized vegetation, orchard, stratum and shrubby hedgerows, flowering meadows,
    • Sustainable management of wastewater leaving the treatment plant to a filtering wetland and a vegetated valley before release into the natural environment,
    • Rainwater management of roads and roofs is carried out via the filter basin and the vegetated valley allowing their infiltration to the plot,
    • A plot of 35 000m2 at 80% permeable to water (paths stabilized, grassed areas of colorful meadows),
    • Access and an educational tour circuit accessible to all, including for people with reduced mobility to a rustic embankment observatory lined with aromatic plants, allows to visualize all the outdoor amenities punctuated by educational and didactic panels,
    • The most balanced HOE® target approach possible, - Biodiversity restored on site at the level of terrestrial flora and aquatic flora,
    • Controlled operating and investment expenses (sustainability, energy saving, facilitated interviews, ...)
    • A quality living environment for residents by the proposed landscaping.


    During the consultation (project management competition) and throughout the design and execution phases, the relationship subsequently established between the project management team and the project management enabled the objectives to be achieved. we had set ourselves. The Community of Communes Eure Madrie Seine has a landscaping following a process of High Environmental Quality in a green plant low ecological footprint in a natural site to protect which gives full satisfaction

    Filter basin for wastewater and recovery of biogas in heat network

    • The wastewater leaving the treatment plant for 34 400 population equivalents with a daily volume at the discharge of a dry peak flow rate of 400 m3 / h and 600 m3 / h peak, are sent to a filter basin d an area of ​​1900m2 then to a vegetated valley of 300ml planted with aquatic and semi-aquatic species, before discharge of water into the natural environment. The waters are purified by the plants. Thus the watercourse is reconquered by many species of fish due to the quality of the discharged water.
    • Rainwater roofing is routed to the vegetated valley before being released into the natural environment.
    • Rainwater runoff from roads is transported to the valley and then returned to the natural environment.
    • The aquatic environments used are the support for the development of biodiversity: amphibians, birds, insects and butterflies grow there and find refuge there.
    • An eco-landscaped plot on an area of ​​35,000m² which includes:
    • Wetland 1,900m²;
    • Vegetalized veins of 300ml;
    • Blue meadow of 4,500m²;
    • Red meadow of 3,000m²;
    • Yellow meadow 2,600m²;
    • Rustic meadow of 4,850m²;
    • Shrub layer 1800m²;
    • Orchards of 2,250m²;
    • Green box of 4000m².
    • In addition, the sludge of the station is treated by anaerobic digestion (Creation of an anaerobic digestion unit and a heat network). Thus, they allow the electricity production towards the ERDF network and the thermal production to heat the public buildings of the CCEMS (Aquatic Center and College). This system makes it possible to achieve a considerable gain in energy which is coupled by the implementation of 400 m² of photovoltaic panels on the treatment plant allowing an annual electricity production of 51,366 kWh / year for a return on investment in 15 years .
    • another technology is integrated into the plant, the filtration of air by plants. A garden of 28m ² is attached to the operating building to filter 4600m3 / h of stale air. All odors and olfactory pollution of the plant are treated by plants.

Reasons for participating in the competition(s)

The entire Aubevoye wastewater treatment plant responds to an innovative HQE® landscaping approach, proposing a positive energy bioclimatic wood exploitation building with an integrated photovoltaic roof at the heart of a site with landscape features defining a eco-landscape. The HQE® reflections carried out were integrated into the operational and technical programming phase of the operating building in continuity with the overall landscaping of the site.
The objective of the project is to design a treatment plant to treat 34,400 population equivalents with a daily discharge volume of 5,400 m3 / d and 600 m3 / h at the peak, and to offer the city of Aubevoye an educational landscape. to integrate the station into its environment while protecting and preserving it.
The landscaping has been to realize a landscape architecture in direct connection with the near and distant environment and in continuity with the buildings and the technical constructions conceived according to a HQE® construction approach in order to treat the water leaving the wastewater treatment plant but also propose landscaping on a parcel of 35,000m² to restore aquatic and terrestrial biodiversity. The innovation in this project was to use plants for their purifying capabilities for both water and air, to restore biodiversity on the site and to create a landscape educational path accessible to all.
Curves perpendicular to the bioclimatic wooden building, delineate areas planted with colorful, rustic, yellow, red, and blue meadows: these meadows are hardy and resistant to regular visits by visitors and site maintenance workers.
Shrubby hedges, made up of an alliance of rustic shrubs (1,800m²), extend the curves of colorful meadows, in the heart of the built-up areas east of the site.
At the western entrance of the plant, in transparency of the green setting, is spread a wetland (with a total surface of 1 900m ²), pond planted with aquatic and semi-aquatic plants (irisaie and cariçais); the thread of the water is an element that comes to structure the landscaping: indeed the wet zone is prolonged in valley of infiltration vegetalized of 300ml planted with Masset and Phragmites australis, plant essences recommended and effective as for the treatment of the pollutions, which crosses different landscape entities, up to the limit of land north-east of the land to finally reach the natural environment. The water leaving the wastewater treatment plant crosses the aquatic basin and the vegetated valley in order to flow into the natural environment. Thus its wetlands are an improvement in the treatment of water before discharge to the natural environment.
To the west of this valley, there is an orchard of 2250m ² made up of apple trees as well as a shrub layer, planted with willow white and birch verrucose.
To the east of this valley is an embankment ramp, allowing visitors to access a rustic observatory and have a view of the entire project.
The rustic observatory is accessible to people with reduced mobility, with a stabilized ramp of 4%, allowing access to this belvedere culminating at 3.00m; the top of the banked banks, is planted with aromatic plants (Lavender, Rosemary, Dill, Fennel and Green Anise), serving as guardrail.
The entire development constitutes a sensitive environmental landscape, which the public can travel through stabilized paths or calcareous sand; decks wooden decking allow to cross the pond vegetation.
Leaving the farm building, there is a filter garden for the air treatment of the plant. Thus, plantations are used as a natural device to filter and deodorize the air inside the building, in the form of a horizontal filter attached to the building. This filter will consist of a substrate thickness responsible for gas treatment. This filter will be planted in the manner of a garden, purifying plants such as grasses, ferns, helophytes and ivy.
The outdoor educational circuit, is accompanied by educational panels, to discover the operating principle of the wetland (planted and vegetated valley), and landscaped gardens.
Special care has been taken in the quality of the environmental service by respecting the natural environment by limiting the deforestation and earthworks interventions to the strict project needs.
A green box composed of different species of trees and shrubs composed of maple field, willow weaver, viburnum obier, Eglantier, ... comes along and thus double the fence, and thus constitutes a vegetation screen in the field boundary
