Water treatment: the route to the faucet

What’s hidden behind the stream of water flowing from your tap? From the storm-water basin to the wastewater treatment plant, from the pumping of water to its sanitization, from the water purification station to the computerized quality control system – follow the circuit of the water treatment.


Our easy access to drinking water almost makes us forget the number of steps the water passes through before being used. With more than half the world’s population living in cities, the performance of infrastructure for easy access to the water is crucial.





From source to tap

To support access to quality drinking water in the overall water cycle, numerous infrastructures are implemented: surface catchment areas, wells drilled into aquifers, and the water pumping equipment. After treatment in purification plants, the water is distributed to the population. Once used, the water is routed to the collection network and wastewater treatment plants (WTPs), so that it can eventually, after treatment, be discharged into the natural environment – into watercourses or directly into the sea.


A VINCI Energies at the heart of the cycle


VINCI Energies acts on the water cycle at different levels. The brand Actemium works with electrical equipment, automation, and supervision as in the Cannes wastewater treatment plant. It also performed design studies and the work required to implement an ultraviolet sterilization step at the Neuilly-sur-Marne drinking water production plant, one of the largest in the world (600,000 m3 of water per day). In Vietnam, VINCI Energies provided the electrical equipment and automation for the nine pumping stations of the Thai Nguyen wastewater collection station.

The Axeau business unit designs, manufactures, and installs the valves regulating water in canal locks, as well as screens to trap solids carried by wastewater, such as at the Bancairon plant in the French Var department .

Other VINCI Energies business units have developed pumping solutions for rainwater catchment basins to prevent flood-related flooding, and participated in the renovation of a water purification plant with activated charcoal to filter the water.
