Carrefour des Gestions Locales de l'Eau 2027 in Rennes

The Carrefour des Gestions Locales de l'Eau (CGLE) is the flagship meeting for public and private players in France's water sector. Across two days, the Parc Expo in Rennes welcomes around 20,000 attendees, 700 exhibitors and a programme of more than 240 conferences, roundtables and one-to-one interviews covering the industry's key challenges: funding, governance, climate adaptation, the full water cycle, and the technical operation of infrastructure. The 2027 edition opens a new hall dedicated to artificial intelligence, data and the digital tools reshaping water management, alongside a dedicated startup area. The programme is organised into themed tracks that follow water from source to sea and back again, helping professionals find practical solutions and expand their networks. Organised by idealCO, the CGLE blends a trade show floor with training sessions and institutional debate, including strategic plenaries and a platform to engage with political decision-makers. For visitors travelling in, the venue sits beside the airport and is well connected to Rennes railway station, making access straightforward.
