We provide a comprehensive service for water supply and wastewater drainage networks. We are expert in all the techniques involved in the collection, piping and treatment of wastewater, the replacement and interconnection of water abstraction pipelines and associated hydraulic structures, drinking water treatment, and the installation and fit-out of dry networks, especially those for electricity supply.


We are also well known for our expertise in optical fibre network engineering to facilitate the rollout of FttH (Fibre-to-the-Home) to areas not already served. Bridging the digital divide is a live and substantial social and regional development issue, and we are very proud to be part of the solution. One of our flagship projects in this market is a public initiative network (PIN) for the French departments of Haut and Bas-Rhin; the first of its kind on such a scale, it serves 700 separate communities.
We are involved in the design, construction and operation of two major public initiative networks in France, totalling 1,500,000 connections; a figure that represents 10% of all the PINs included in the French Superfast Broadband Plan.
