April 2025
The initiative to upgrade the electrical infrastructure of the Catacombs, led by Imerys, was implemented with a dual focus on safety and visual enhancement, ensuring a smooth and high-quality experience for all visitors. Works included the installation of two new electrical panels, the routing of 500 meters of cabling using protective conduit, the placement of 80 LED fixtures, repair of existing lighting units, and the installation of two new emergency lighting systems.
In addition, the emergency exit notification system was restored to reduce exposure to CO₂ levels inside the Catacombs, an essential factor for ensuring visitor safety and preserving air quality.
The completed initiative delivered significant and multidimensional benefits. Most importantly, it ensured the uninterrupted and safe operation of the Catacombs by adhering to strict safety standards and replacing outdated or inadequate systems. This is especially crucial for a high-traffic archaeological site where the safety of visitors and staff is paramount.
Furthermore, the upgraded infrastructure drastically reduced the risk of accidents or technical failures that could endanger lives or cause damage. Imerys has thus provided a reliable and secure environment, enhancing public trust and the confidence of local stakeholders.
The energy-efficient upgrade, based on the installation of modern LED lights and optimized cabling, delivered measurable cost-saving results. LED fixtures are known for their energy efficiency and long lifespan, reducing both power consumption and maintenance needs. As a result, operational costs were significantly lowered.
Moreover, using protective conduit safeguarded the installation from environmental damage, extending the lifespan of the system and minimizing future repair costs.
This action reinforced Imerys' reputation as a responsible and innovative company that prioritizes safety, quality, and respect for cultural heritage. It also positioned the company as a model of corporate responsibility and sustainable development, strengthening its public image and opening the door for future partnerships.
The completed upgrade was not merely a technical project—it had a far-reaching impact on operations, visitor experience, the local community, and Imerys’ workforce. Key outcomes include:
Overall, the initiative upgraded both the functionality and cultural presentation of the Catacombs, while also deepening Imerys’ connection with its community and reinforcing a sustainable and responsible business model.
