Consulting and Engineering on the entire water cycle

Thanks to our skills and our local roots, we are present at all stages of your projects: from upstream strategic advice, studies and master plans, to the design and supervision of the works and deconstruction.

Our engineers advise you on all your projects to:

• Ensure the resilience of territories to the effects of climate change (protecting water resources, researching and developing new resources)
• Imagine and bring to life the cities and industrial sites of tomorrow
• Build high-performance and sustainable infrastructure that contributes to the attractiveness of the territories
• Provide long-term access to essential services
• Support the implementation of public policies
• Reconcile the economic, environmental and social performance of your projects

To support our clients in all environmental and energy transitions, our engineers are also involved in other key areas of the territories: management of the large and small water cycle, urban development, waste management and recovery, mobility.

In an ever-changing urban context, we work with local authorities and building owners to design efficient and sustainable drinking water, sanitation and stormwater infrastructure. From initial planning to implementation and monitoring, we offer comprehensive support to ensure water quality and availability while minimising environmental impacts.

Balanced watershed management is essential to preserve our water resources. In partnership with managers and local stakeholders, we develop integrated strategies to maintain and restore the quality of aquatic environments. From flood prevention to climate risk management, we offer innovative solutions to ensure the sustainability of aquatic ecosystems.

Faced with the challenges posed by climate change and coastal risks, we design robust and sustainable port infrastructure to guarantee the safety of maritime activities. By integrating the principles of sustainability and biodiversity preservation, we contribute to the ecological transformation of ports while strengthening their economic and tourist attractiveness.

Through our multidisciplinary expertise and commitment to sustainability, we are at your side to address the complex challenges of water management and build a resilient future for all.

• Ecological Restoration of Environments and Prevention of Flood Risks (GEMAPI)
• Ecological engineering operation using mangrove development 
• Implementation of bioplastic seagrass beds to restore juvenile habitat with ReFish™

How can we reduce the risk of flooding while preserving biodiversity? What solutions should be developed to restore the ecological functions of vulnerable areas? What governance should be adopted to optimise greenhouse gas emissions and maximise the use of nature-based solutions? These are all challenges taken up by our Consulting & Engineering teams in Haute-Savoie, along the Dranse Delta!

For several years, the perimeter of the historic area of the Dranse delta has been facing a very strong urbanisation linked to the development of industries, tourist activities and the development of new residential areas. The Basse Dranse, between the Pont de la Douceur and the delta of the Dranse, presented a vast space where the river meandered.

The flood of 2015 was a reminder of the potential for flooding in this downstream part of the Dranse and the interest of an eco-morphological restoration of this area.

Our Consulting & Engineering teams support the Chablais development syndicate in the restoration of the ecological functions of the watercourse.
