Background

The VINCI – Grand Paris Line 15 Project // Villejuif and Cachan (94) at a glance

The T10 is now operating on Line 15 of the Grand Paris project. VINCI placed its trust in ECL-Econet by installing two Econet T10 units on the Villejuif and Cachan sites. This solution enables water discharge in full compliance with French water regulations.

Before reaching our treatment station, the water follows a complete pre-treatment sequence. It is first directed into an initial settling tank, then into a second one before entering our treatment system. These preliminary steps remove the first suspended solids. Elle est d’abord envoyée dans un premier bac de décantation, puis dans un second avant d’arriver dans notre station de traitement.

The decanted water then enters our T10 station. First, it is filtered to 91 microns through our BIG BAG filter equipped with a specific felt and mesh. Next, it passes through a second filtration stage, ranging from 25 microns (oil-removal) down to 1 micron. Finally, before discharge, CO₂ injection is performed to neutralise the pH.
