Rainwater retention and infiltration tunnel

Function

The retention and infiltration tunnels promote the infiltration of rainwater into the plot. The infiltration allows the depollution of chemical and / or bacteriological water by filtration in the soil and ensures the recharge of the water tables. It also regulates discharges into surface environments during heavy rain episodes.

Composition

The rainwater retention and infiltration kits consist of tunnels, boxes and accessories.

A collection box, placed upstream of the infiltration zone, allows both the distribution of rainwater and its pre-treatment by ensuring the trapping of suspended matter and macro-waste.

A looping box allows you to control the device.

The boxes are supplied as standard with an extension surmounted by a ventilated cover ensuring aeration of the system and its decompression.
