An infiltration trench is an excavated channel in the ground. It is filled with porous material and collects water that runs off buildings, roads or other impermeable surfaces.
The water then soaks into the surrounding soil and improves groundwater levels. Infiltration trenches increase permeability and reduce stormwater flows.
Infiltration trenches can be a useful tool to help keep our trees healthy.
