Water and sewerage projects by Soletanche Bachy

In our cities or our countryside, water management networks allow us to carry out our daily tasks without even needing to know they’re there... But do you know how the water gets to your tap and what happens to it after you’ve used it?


A saga following the water cycle

Every two weeks, we invite you to follow the saga of the water cycle and find out what happens to water in its raw, clean and used states and how Soletanche Bachy is working around the world to build infrastructure vital to public health and preservation of our environment.  

You will find out about the structures we have created, in various shapes – rectangular, circular, two- or three-lobe – and deep- or semi-underground, such as water treatment stations, water tanks, collectors, sewers, outfalls, etc. and better understand how water and sewerage management works in our cities

An expertise to support water and sewerage projects

Soletanche Bachy is present at every stage of water management and creates “turnkey” sewerage structures, from the design and execution of the foundations to the civil engineering works and delivery. 

Our experience in deep excavation projects allows us to master the geotechnical difficulties specific to each project, using the full range of existing techniques: diaphragm walls, waterproof screens, tunnels, soil improvement, barrettes, civil engineering, ground anchors, wells, piles, ground-freezing, etc. 

Over the course of numerous projects, we have also acquired a broad knowledge of all the equipment specific to sewerage: lift pumps, screening, cleaning, emptying, deodorant, treatment, measurement, remote monitoring systems, etc. We are therefore able to offer the most suitable equipment for each project and oversee their implementation ourselves.
