Join us in Les Sables-d’Olonne

Water Reuse Europe third Conference and Exhibition on Innovation in Water Reuse will take place in Les Sables-d’Olonne. Les Sables-d’Olonne is an exquisite and lively town bordering the Atlantic coast of France, in the Vendée Department, a popular holiday destination in France. Renowned as a city of yachting, the port is the start and finish point of the prestigious Vendée Globe sailing race round the world. 

But Vendée is also one of the most water stress region in France, and is now pushing innovation on water reuse with the trialling of the first French scheme reusing treated wastewater for indirect drinking water production – the Jourdain Program.

The conference brings together professionals and organisations active in the water reuse sector for a two-day event packed with presentations from prestigious speakers on a wide range of topics, discussions, and technical visits.

We therefore invite developers, industry leaders, solution providers, technology suppliers, policy makers, researchers, end-users, and consultants to share with us their experiences and perspectives on water reuse in Europe.

The conference venue is Les Atlantes Conference Centre. Located in the heart of Les Sables-d’Olonne, Les Atlantes Conference Center is located a 10 minutes walk away from the station for easy access, and faces the sea to combine business with pleasure.

Our Conference dinner will be held at Les Atlantes Conference Centre on the evening of the 24th of September.

The conference is organised with the kind support of Vendée Eau

Vendée Eau is a non-profit public body in charge of water supply in the French department of Vendée. The company is developing a range of solutions to prevent from the risk of water shortage in the future, including desalination and wastewater recycling for indirect potable reuse, notably through the Jourdain Programme.

Conference Programme

Taking place over two days, our conference will offer a mixed programme of talks on innovations in water reuse project development, design, and technology together with keynotes to set the scene and review current developments in the sector. The conference will more specifically cover the following theme: water reuse for potable applications, public health in water reuse, water reuse in agriculture, innovative solutions in water reuse, and industrial water reuse. We aim to attract an audience of around 130 delegates for what we anticipate will be a landmark event for Europe’s maturing water reuse market.

Our conference programme is under progres.

Technical tour

With the support of Vendée Eau, a technical tour of the Jourdain Water Reclamation Scheme will take place on the second day of the conference.

A national first, the Jourdain programme is France’s flagship project for indirect potable reuse, demonstrating that the country has the technologies and the commitment at the local level to address the challenges posed by climate change, supporting the ambitions of France’s new Water Plan to increase wastewater reuse from 1% to 10% in 5 years.
