the eloy mission

The eloy family business has grown continuously for over 50 years. 500 skilled employees now work with our customers on all of their construction and wastewater treatment projects. We work around the world with the same goal: to create, treat, demolish, rebuild and provide solutions.

éléments naturels


The natural world has been in perfect harmony for millions of years. It has enabled life to grow and humanity to develop. If threatened, the balance will become fragile, with potentially catastrophic consequences for the Earth and everything living on it.

As a major player in construction and wastewater treatment, we have a role to play and responsibilities to assume. That’s why we’re committed to designing solutions, products and projects that preserve the balance of nature essential to ensuring the preservation of life on our planet.

The eloy spirit: commitment. Commitment to our customers, our employees and our planet. Commitment means making choices and being responsible, which we have done and been for over 50 years.
Olivier Eloy
