Who are we?
As a global leader in the water and waste management sectors, we have been operating for over 160 years all over the world. We provide essential services to protect the resource and improve quality of life wherever we operate.
We support you to
Manage crises and water stress
We help you to anticipate and forecast the state of resources, as early and as accurately as possible, to avoid and manage crises and water stress.
Promote good consumer practices
Water is a rare and essential resource that must be preserved. We work with you to encourage sobriety through responsible water consumption.
Valorise sludge
We're here to help you reduce the amount of sewage sludge you generate and make the most of its energy potential through innovative solutions such as methanisation, incineration and thermochemical processes.
Manage crises and water stress
We ensure a continuous water supply despite the increasing number of droughts and shortages. Using artificial intelligence, we model the state of water resources to prevent and effectively manage crisis situations.
Droughts and water shortages are becoming more and more frequent, putting pressure on the availability of water resources. To guarantee a continuous water supply, we anticipate the quantity and the quality of water resources in order to prevent deterioration and make the right decisions.
We use artificial intelligence to model the state of water resources in the short, medium and long term, in order to predict emergencies and avoid crises. In the event of a drought alert or low groundwater levels, we take appropriate preventive and restrictive measures to limit use and maintain groundwater levels. These restrictions are essential until it rains again to ensure the preservation of water resources and continuous distribution in your area.
We involve our experts and offer alternative solutions suited to your situation.
Since 2006, we have been working on building the Moreau dam in Guadeloupe to help local farms cope with frequent droughts.
Promote good consumer practices
We promote cautious use of water by means of responsible and sustainable consumption. It is becoming essential to take action on a daily basis to limit our consumption by changing how we use water.
To encourage sustainable management of water resources, we have developed a range of resilient solutions to complement water meters in private and public housing. Remote meter reading is essential in helping users to monitor their consumption and use water more sparingly. We have fitted smart meters that allow for real-time monitoring and issue alerts if too much water is used, optimising how much water individuals and businesses use.
You get a complete overview of water consumption in your area, thanks to artificial intelligence and analysis of data from water meters. This allows you to measure the impact of water use over time, understand local consumption trends and make the right decisions. Price incentives can be used to change habits.
We have launched an innovative new performance-based contract: the water saving contract. In partnership with the authorities in Brive, our shared aim is to reduce use of water resources by 6 million m3 by 2027. We operate the public water and wastewater service with the target of reducing the amount of water taken from the natural environment by 21%.
Valorise sludge
To support the ecological transition on a regional level, we turn sewage sludge from wastewater treatment into a local, renewable energy source.
We harness the energy potential of nitrogen- and phosphorus-rich sewage sludge from wastewater treatment plants, converting it into energy (heat, electricity, biomethane) or organic matter using innovative solutions such as methanisation, incineration and thermochemical processes. Sludge can be used as an organic fertiliser instead of chemical fertilisers, helping to promote more sustainable agriculture.
We work with you to define the most appropriate treatment and recovery process for each type of sludge produced and the context for each wastewater treatment plant, taking account of the challenges faced and local regulatory requirements.
Our solutions aim to turn sewage sludge into a high value-added material that helps to reduce your area’s greenhouse gas emissions, support the transition to cleaner energy sources and develop the circular economy in water treatment and agriculture.
We create local circular economy loops from wastewater and waste to support the energy transition in local areas. The Sausheim methanation plant in Mulhouse converts 100% of sewage sludge into green gas, treating sludge equivalent to 490,000 people and producing 2,000,000 Nm3 of purified biomethane every year. This green gas is used to power 44 buses in the Mulhouse area, while biomethane not used by buses is used to power Mulhouse Alsace Agglomération buildings. The 125 buses in the fleet will run on biomethane by 2034.
