Overview
In the spring of 2023, JAS Hennessy & Co initiated a project to expand the parking facilities of their bottling plant in Salles-d’Angles, Charente, France. This expansion was necessary to support the increased production capacity of their new 26,000 m² facility, situated on a 30-hectare site in the Pont-Neuf business area, approximately 7 km from Cognac. The project involved the installation of a permeable parking area using OSMORIA Indigreen aquatextile, designed to infiltrate and depollute run-off water, ensuring environmental sustainability.
Challenge
Hennessy, known for its commitment to environmental sustainability, faced the challenge of expanding its parking and access roads while minimizing ecological impact. The expansion needed to protect the local environment, including the preservation of biodiversity. The project required an effective solution to manage and treat run-off water, which could contain hydrocarbons and polycyclic aromatic hydrocarbons (PAHs) from vehicle emissions and oil leaks. The aim was to ensure clean infiltration of water into the ground, preventing pollution and maintaining the integrity of the surrounding ecosystem.
Solution
The chosen solution for the parking expansion was the OSMORIA™ Indigreen® aquatextile, a high-performance, depolluting geotextile. The access roads to the parking area were paved with permeable concrete, while the 100 parking spaces were constructed using permeable grass pavers. The infiltration structure was enhanced with 2,275 m² of OSMORIA Indigreen aquatextile, which effectively depollutes run-off water from hydrocarbons and PAHs during infiltration.
Installed beneath the bedding layer, the OSMORIA Indigreen aquatextile manages both diffuse pollution (chronic oil leaks) and localized accidental pollution (illegal oil dumping). The aquatextile instantly infiltrates water due to its high permeability (> 10⁻² m/s) and irreversibly fixes over 99.5% of passing hydrocarbons. The residual hydrocarbon content after passing through the infiltration structure is ≤ 1 mg/l.
The aquatextile’s filaments provide mineral nutrients that promote rapid colonization by microorganisms present in the soil and water. These microorganisms degrade hydrocarbons, ensuring long-term protection of the soil from pollution. The aquatextile's retention capacity remains effective for over 50 years, offering an autonomous, durable, and maintenance-free solution for managing run-off water pollution.
OSMORIA Indigreen is specifically designed to handle pollution from light and heavy vehicles parked on permeable surfaces, making it an ideal choice for environmentally conscious infrastructure projects.
