Preserving resources

  • Vue aérienne d'un réservoir vert émeraude avec un barrage en béton incurvé à gauche, bordé par des forêts luxuriantes. Sur la rive droite, un chantier avec une grue orange et des barrières flottantes dans l'eau est visible.

    A commitment to environmental challenges

    We design and build high-performance wastewater treatment plants to serve local authorities and protect the quality of aquatic environments.

    Integrated expertise

    From engineering through to commissioning, we draw on our expertise in industrial civil works and resource management.

    Engineering and sizing of facilities

    Our involvement starts from the early studies to define solutions that are always adapted to local needs.

    Thanks to our expertise-structured organisation, we are able to draw on specialised teams in industrial civil works and resource management, ensuring the reliability, durability and performance of wastewater treatment facilities.

    Building complex technical facilities

    We construct complex treatment plants incorporating basins, process buildings, technical equipment and associated structures.

    Drawing on extensive experience with highly technical projects, we manage all works with rigorous coordination, careful interface management, and strict adherence to safety and quality requirements throughout the construction process.

    Optimising projects from an environmental perspective

    In line with our ambition of “building for life”, we integrate environmental considerations from the earliest design phases: resource optimisation, carbon footprint reduction and a continuous pursuit of performance.

    This approach is guided by our Climate strategy and SBTi-validated objectives, which shape and guide our commitments.

    High safety standards on site

    Health and safety are essential, non-negotiable principles on our sites.

    We apply exacting standards and work closely with all on-site teams to ensure safe and responsible working conditions for our people and partners alike.

Facilities that are key to water management

At the centre of public water policies, wastewater treatment plants are essential infrastructure for preserving resources and maintaining the quality of natural environments. We design and build high-performance plants capable of meeting environmental, regulatory and demographic requirements.

With our expertise in industrial civil works, we develop plants that take full account of operational needs, ease of maintenance and future scalability.

Our experience with highly technical projects, in France and internationally, enables us to support our clients – local authorities, operators and partners – in delivering reliable, resilient infrastructure tailored to the challenges of water management.
