SIZIAF is the manager of a 460ha industrial estate located in the Douvrin and Billy-Berclau municipalities. It is responsible for the structural development, management and economic growth of the Artois-Flandres industrial park.
Geared primarily towards industrial companies, the first firm to locate to the estate in the late 1960s was La Française de Mécanique.
This industrial estate continues to grow today. A new 90ha plot was freed up and redesigned on the former Française de Mécanique site, notably for the firm ACC, winner of the French government’s recovery plan for the car industry and innovative entities. ACC is Europe’s leading manufacturer of car batteries.
In this context, SIZIAF called on the SADE (agent) – Eurovia consortium to make these future plots viable. This servicing task consisted in providing access to water supply, gas networks, telecommunications and fire safety facilities. It also included public drainage with pre-branch connections on the plots in question.
Within 10 weeks, from October to mid-December 2021, SADE laid a drainage network, at an average depth of 4.5m, converging at a pre-existing pumping station.
The teams from the Artois-Lens Agency also built the water supply and fire safety networks in 250mm-diameter cast iron. To overcome specific hurdles such as a traffic roundabout, two directional drilling operations of 315mm and 250mm-diameter were carried out to lay sheaths designed to house the gas and water supply networks.
Once the networks were in place, Eurovia carried out road surfacing and landscaping works.
An environmental aspect
As the networks were to pass through wooded areas, the works were to comply with the Green Worksite Charter and longstanding environmental measures imposed by the Artois-Flandres industrial park. In association with a co-contracting organisation for project management, particular care was taken to protect bats, amphibians and orchids, with the laying of nets to cordon off protected areas on the worksite.
