Infiltration Chambers & Infiltration Trench Pipe

Infiltration chambers (aka, “leaching chambers” or “subsurface outlet chambers”)

I far prefer the use of these bottomless, louver-sided plastic chambers over the use of perforated pipe in French drain applications. The larger-capacity chambers will not clog with roots like perforated pipe will.

Their “Quick4 Standard Chamber” is good for infiltration trench, subsurface greywater-harvesting, and septic leach field applications since its height does not exceed 12 inches (30 cm). This way the majority of the water discharged through the chambers infiltrates into the top 2 feet (0.6 m) of soil where roots and soil life can more readily utilize the water.

But even better, is their Quick4 Plus Standard Low Profile Chamber, which is only 8 inches (864 mm) tall—so you can infiltrate water higher in the soil profile where there is more life that can filter and utilize the water.
