From 26 to 28 August 2025 in Bordeaux, join us for the second edition of the OneWater Scientific Days!

Two years after the first edition in Lyon, the national exploratory research programme OneWater – Eau Bien Commun invites you to meet again for three days of exchange and collaboration.

This year, scientists, territorial stakeholders, water managers, students, and all those interested in water issues are invited to share, question, and co-develop ideas around freshwater as a common good.

Whether you are discovering OneWater – Eau Bien Commun for the first time or following its progress, these three days will provide an opportunity to:

  • (re)discover the programme,
  • discuss ongoing scientific challenges,
  • and build connections around concrete solutions for sustainable water management.
For those who wish to attend

Registration has been extended for everyone until Thursday, 13 June 2025 at 6:00 PM.
