As their name suggests infiltration chambers work exclusively to infiltrate stormwater. They are an underground facility and are often used beneath parking lots or playing fields to treat flow routed from other areas.

Both modular systems require a lower bedding layer of angular stone to permit infiltration, and provide a foundation for the installation:

*Plastic modules usually have a parabolic shape to resist the load above. The spaces between the rows of the gallery are then filled with more clear stone to support the overlying infrastructure.
