Our story


More than a family story, Delta Service Location is a story of men and women motivated to work well. Everything started in 1980…


Michel DENIS founded Delta Service Location in Saint-Fons (69). He had in mind providing his customers with pumping equipment, particularly in the area of a construction and public works. It was no accident that the word “Service” appears in the chosen name: he provided services such as installation or maintenance included, with the aim of providing reliability and maximum service.


To guarantee increased responsiveness without depending on other service providers, DSL bought its first generators. Construction dewatering, an activity that was still little known in France, was introduced by DSL according to the deep well technique.


DSL targeted the south-west and opened its second branch in Toulouse, followed close behind by Strasbourg in 1990.


The concept of maximum service led the expanding team to provide more and more services: design, transport, installation, monitoring, on-call service, repair, sales etc.


The headquarters and the Lyon branch were outgrown and the company moved to Corbas (69). A few years later, in the full economic crisis, Delta Service Location surprised everyone by investing massively to modernise its stock of equipment and train its teams, more convinced than ever of the importance of human capital that was the power behind a strong SME.


With the aim of providing more and closer responsiveness, the national coverage developed with new branches in Tours in 2001 and Marseille in 2009.


This new decade started with the opening of a branch close to Paris in 2010. In 2014, Xavier DENIS took the reins of the company, after spending several years in the management team. New branch openings followed with Lille in 2014 and Bordeaux in 2019.


At the beginning of 2021, DSL passes a milestone by acquiring the 3 companies of the Rabatech group (ERF, Neptune Pompage and Action Écologie). These acquisitions consolidate the group’s position on construction dewatering and pumping market, by developing its range of expertise, particularly in drilling and water treatment.


Today, there are more than 220 colleagues working together to complete your projects, with a partnership logic in the service of performance.


And tomorrow? We will be at your side for all your projects, whatever the challenges they present, and that is what we continue to be motivated by.
