 Infiltration trenches are highly susceptible to clogging with sediment.  As a result, geotextile filter fabric must be used to line the trench to prevent the surrounding soil from mixing with the stone.  Runoff directed to a trench must be routed through a pretreatment device before entering the trench.  Pretreatment of the runoff will help to prevent clogging of the trench from sediment as well as preventing groundwater contamination from pollutants contained in the runoff that is being infiltrated to the groundwater.  Basins receiving runoff from rooftops only do not require pretreatment.
-To divert large flows, a subsurface drain may be placed in the center of the trench, 2 feet from the surface, to prevent these flows from bypassing treatment (refer to [[Subsurface Drain]]).
