Séché Environnement Group incorporated eight centres specialising in maintenance services for wastewater networks and facilities, which previously belonged to Veolia subsidiary SARP OSIS-IDF. News of the acquisition was announced back in August 2021. This move not only extends Séché Environnement's portfolio of services, but also strengthens its footprint in the Greater Paris region.

On 1 January, the Séché Environnement Group opened its doors to eight operations centres and their 233 employees offering expertise in maintaining wastewater networks and servicing wastewater facilities across the Greater Paris region. Harnessing a fleet of over 130 production and service vehicles (high-pressure cleaning trucks, tanker trucks, pumps, etc.) as well as network video inspection technologies, the teams will continue leveraging their expertise to service the needs of a wide range of customers, including local authorities, manufacturers, real estate and food service professionals, and private individuals.
