How we’re saving water
We’re launching a variety of projects that support France’s campaign to save water. We aim to cut our consumption 10% between 2023 and 2030 and 25% by 2035, in the 100 sites in France that consume the most.
Water is a vital resource for our health, our ecosystems and our economy, with uses in agriculture, industry and the energy sector. Ensuring that we have enough clean, safe water, without disturbing the balance of nature, is in everyone’s interest.
Why it matters
SNCF Group accounts for around 0.1% of France’s water consumption, and around 3% of consumption in the French industrial sector. That’s very little for a business our size. But water is an asset we all share, and we can’t deliver rail service without it—which makes this increasingly scarce resource doubly important for us.
What we’re doing
Together, employees across SNCF Group have committed to measures that will cut our water extraction by 10%. These actions include:
- using high-precision tools to improve detection of water leaks
- adopting carefully defined alert levels to guide our response to drought
- limiting water uses to the bare minimum, such as washing rolling stock, equipment and facilities, and watering green spaces
- collecting and reusing rainwater
- encouraging everyone at SNCF Group to adopt simple, everyday habits that save water.

How we use water
At SNCF Group, we use water primarily to:
- maintain and clean trainsets
- maintain and improve track and green space, and clean service vehicles, stations and other facilities
- provide drinking and plumbing water for our customers and employees
- fight fires
1 million liters saved thanks to a connected washing station
At the Pays de la Loire maintenance centre near Nantes, teams have developed a smart new system for their train-washing stations. Proprietary eco-friendly fleet-management modules known as écoFLOT are integrated into the automated boxes that detect train arrivals and departures. These modules identify each TER trainset as it passes, alert the driver when a wash is needed, and record and transmit detailed data on the duration of each washing cycle.
Since the rollout of écoFLOT modules in November 2024, the system has already saved:
- 1,123 washes
- 1,572 kWh of energy
- 1.17 million litres of water, enough to fill half an Olympic swimming pool
The écoFLOT modules serve two purposes: they help optimize water consumption in train-washing stations and enable predictive cleaning to improve overall washing station efficiency.
The French government’s action plan
In 2022, France endured a historic drought, and groundwater levels failed to recover the following winter, when the country went a record 32 days without rain. To conserve this increasingly scarce resource, the Energy Transition Ministry adopted a resilient, coordinated water management plan that calls for cutting water extraction 10% by 2030. Though SNCF doesn’t rank among France’s major water consumers, we want to be a part of this nationwide campaign. Our goals are to cut extraction 10% between 2023 and 2030 and 25% by 2035, in the 100 sites in France that consume the most.
