Rainwater infiltration works reintroduce water into public spaces and restore the water cycle. These structures temporarily store runoff water, then encourage its infiltration into the ground. They can come in different forms: surface infiltration (swale, open-air basin), by surface covering (permeable slab or paving stone) or buried (road with reservoir structure). In addition to their technical function, these structures play a landscaping role and can serve various uses such as green spaces or play areas. These alternative solutions are increasingly adopted in peri-urban areas to optimize the use of land space.
Permeable pavements
Permeable pavements help manage stormwater, reduce flood risks, recharge groundwater, and mitigate urban heat islands. Using materials like OSMORIA Indigreen aquatextile improves water infiltration by filtering pollutants, reducing reliance on stormwater networks, and aligning with ecological policies. This enhances resilience to climate impacts, protecting soil and water resources.
Swales
Swales are shallow grass-covered channels that manage runoff by slowing water flow, filtering sediments, and aiding infiltration. They blend into landscapes, require low maintenance, and reduce impervious surfaces. OSMORIA Geoclean improves these systems by filtering pollutants, maintaining constant performance, and supporting ecological goals like stormwater management and resilience policies.

Ditches
Infiltration ditches capture and infiltrate runoff locally, recharging groundwater and offering thermal cooling. OSMORIA Geoclean aquatextile enhances these ditches by treating 100% of infiltrated water, ensuring safe groundwater infiltration. Benefits include independence from stormwater networks, reliable performance in all conditions, and alignment with ecological policies.
Open-air basins
Surface infiltration basins are vegetated ground excavations that manage runoff, reduce flooding risks, and increase groundwater recharge. Used in large areas, they also help mitigate urban heat. OSMORIA Geoclean improves basin performance by treating stormwater, eliminating hydrocarbons, and offering easy installation, ensuring long-term, cost-effective stormwater management.

Buried basins and tanks
Underground infiltration basins collect and infiltrate stormwater, reducing flood risk and network saturation. OSMORIA Geoclean aquatextiles treat polluted runoff by removing hydrocarbons and PAHs, ensuring clean infiltration. These basins work in low-permeability soils, support land use above, and are compatible with fluctuating water tables.
Infiltration wells
Infiltration wells (sump pits) manage water quantity and quality by storing rainwater and allowing it to infiltrate through gravel or perforated structures. They handle runoff from impermeable areas and prevent pollution by treating water at the point of infiltration. OSMORIA Geoclean enhances this by removing contaminants like hydrocarbons.
Infiltration trenches
Infiltration trenches are shallow, gravel-filled structures designed to manage stormwater in limited spaces by storing and allowing runoff to infiltrate into the surrounding soil. They reduce flooding, recharge groundwater, and can be installed in urban or suburban areas. OSMORIA Geoclean enhances these trenches by treating 100% of infiltrated water, removing hydrocarbons.
Reservoir pavements
Reservoir pavements store stormwater, allowing it to infiltrate the subsoil or be discharged at a controlled rate. OSMORIA Geoclean aquatextile treats infiltrating water, removing hydrocarbons and pollutants, ensuring clean infiltration. It offers a long-lasting, maintenance-free, cost-effective solution, with performance tailored to hydrocarbon pollution levels.
