Your challenges, our solutions

Preserve and save our water resources

We can help private and public sector operators manage your water resources to ensure sustainable, environmentally-friendly consumption. By analysing needs, assessing impacts and proposing appropriate solutions, we advise you on how to preserve water and aquatic environments.

Our teams have expertise in the entire water cycle, whether we are talking about drinking water, wastewater or aquatic environments. We have many water treatment and sanitation specialists.


Anchored in the heart of the territories, they have a detailed knowledge of local issues and problems, to provide you with tailor-made answers and solutions.


Through our long history of building networks, delivering tap water to every household and monitoring the consumptions through meters, we have forged a knowledge that we know apply for you, to help you and your users to have the best resource management possible. Our committed teams are keen to help every customer on its path to sustainable water services.

Water management is key for the future and addressing this issue means taking into account all the stages of the water cycle.
Michael Colson, General Manager of Consulting & Engineering entity of SUEZ
Our missions: to preserve and save our water resources, reduce consumption, provide water that complies with drinkability criteria, optimise treatments, ensure the sustainability of the performance of structures, enhance coastal and port areas as well as all protected areas and guarantee the quality of the water discharged in accordance with the acceptability of the receiving environment.

Frequently Asked Questions

There are many solutions around the world to fight against water scarcity:

Efficient water management: Improving water use efficiency for the lowest possible consumption through innovative agricultural practices, advanced irrigation technologies and efficient water distribution systems.

Water conservation: Encourage measures such as repairing leaks, installing water-saving devices (e.g. in taps or showers) and promoting responsible consumption behaviour.

Rainwater catchment: Collecting and storing rainwater for later use in irrigation, domestic or industrial water supply, promoting its infiltration.

Wastewater recycling: Design wastewater recycling systems to reuse treated water in non-potable applications such as irrigation or industrial uses, where possible.

Groundwater recharge: promoting groundwater recharge to make water available at the right times.

Watershed management: Adopt an integrated approach to watershed management to ensure equitable distribution of water among different users while preserving aquatic ecosystems.

The use of desalination technologies: Invest in desalination technologies to convert seawater into fresh water and then into drinking water.

Our experts support you in defining global strategies for sustainable and resilient development.

Whether you are a local authority or an industrial company, we co-construct your climate, air and energy strategies and roadmaps through 4 main steps:

  • Climate, air and energy diagnosis to identify the main issues to be addressed: GHG emissions assessment, analysis of renewable energy potential, identification of vulnerabilities to climate change, life cycle analyses, etc.
  • Development of a strategy to reduce the carbon and environmental footprint
  • Definition of the tailor-made action plane: with in-depth expertise in key areas such as the diagnosis and recovery of waste heat and industrial energy systems, the optimisation of the supply chain, the deployment of mobility plans, the development of training and awareness raising for stakeholders, etc.
  • Activation of green finance tools for the financing of actions: financial operations and tools in favour of the ecological transition and the fight against climate change.

We provide you with our specific know-how dedicated to carbon credit certification, eligibility and impact studies of regulatory mechanisms for carbon taxation and finance, etc.
