Know-how
Experience and skills
The success of our projects is based on our respect for simple rules, applied since the company was born.
In studies
Sizing rules are inspired by Cemagref research expressed mainly in the following three documents ( in French ):
The R&D service builds on these rules, drawing on feedback from our experience in building over 650 plants, all still operational.
Example 1 - our criteria for choosing sands for the second stage are stricter than those of Cemagref.
Example 2 - we feed the second stage more slowly than the pace usually recommended.
The Studies Service designs each project with technical and economic optimisation in mind.
Example 1- 3D modelling is used to ensure balance during excavation between the clearing and banking operations and thus reduces or even avoids the need to remove or add material.
Example 2 - our Bi-filtre planté® process often works without a sewage pumping station, unlike the traditional piled up two-stages system.
The worksite
Our projects are run by four experienced works managers who have carried out dozens of such projects.
With the experience of 600 installations, we have encountered most of the problems connected to planted filter bed treatments, especially connected to excavating terrains made difficult by rocks, groundwater,unstable lands and complex access.
Example - a filter is not installed in the same manner in calcareous rock and in basalt rock.
We have developed a network of local public works enterprises that have thorough knowledge of the terrain and the environment and work with us on our studies and offers.
