The 600-liter infiltration tunnel is the advanced, high-capacity solution for sustainable stormwater management and efficient drainage. Designed specifically for residential, commercial, and industrial applications, this infiltration system channels, retains, and returns rainwater to the ground naturally, drastically reducing sewer system overload and preventing flooding. Its state-of-the-art engineering ensures an extremely robust structure, certified to withstand frequent light and heavy vehicle traffic when installed with the appropriate lining, maximizing the use of surface space without compromising structural safety.

This modular system stands out for its ease of installation and excellent hydraulic performance. With a usable storage capacity of 600 liters per individual module, it offers a significantly larger retention volume compared to traditional gravel systems, considerably reducing excavation and earthmoving. It is the perfect eco-friendly alternative for complying with current Sustainable Urban Drainage Systems (SUDS) regulations, integrating discreetly and underground into any urban development project, parking lot, landscaped area, or industrial park.

Frequently Asked Questions

What load capacity does this filtration tunnel support to allow the passage of vehicles?

The system is designed with high structural strength which, following the correct guidelines for installation depth and soil compaction, perfectly withstands the continuous traffic of light and heavy vehicles, making it the ideal option for installation under parking lots and road access areas.

Is it difficult to install compared to traditional gravel systems?

No, the installation is considerably faster and cleaner than traditional gravel trenches. Because the modules are prefabricated and lightweight, the required excavation volume is drastically reduced and assembly is simplified, resulting in significant savings in time and labor costs.

Can multiple tunnels be connected together to achieve greater capacity?

Yes, the modular design allows you to join as many tunnels as needed in line or in parallel, adapting with total flexibility to the required retention capacity according to the dimensions of the rainwater collection surface and the specific needs of each project.

What maintenance does this rainwater drainage system require?

Due to its underground location and optimized design, maintenance is minimal. The prior installation of a settling basin or sand trap and geotextile lining is recommended to prevent the entry of coarse sediments, leaves, or sand into the tunnel, thus ensuring optimal performance for decades.
