Water treatment: The route to the tap

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 sanitisation, from the water purification station to the computerised quality control system – follow the circuit of water treatment.

traitement-eauOur easy access to drinking water almost makes us forget the number of steps 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 water is crucial.

From source to tap

To support access to quality drinking water in the overall water cycle, numerous infrastructure are implemented: surface catchment areas, wells drilled into aquifers, and 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.

VINCI Energies at the heart of the water 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 sterilisation 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.

Other VINCI Energies business units have developed pumping solutions for storm-water basins référence SEIT Hydr’Eau/Le Havre) to avoid flood-related overflow, and participated in the renovation of a water purification plant using activated carbon (référence Etavis Kriegel&Schaffner AG/Bâle) to filter the water.
