Infiltration chambers are used for subsurface greywater and blackwater distribution. In addition, they can be used in place of perforated pipe in French drain systems. They don’t clog with roots due to their large void space, so perennial planting, such as fruit trees, can be placed beside them to utilize the water.

Their “Quick4 Standard Chamber” is ideal for French drain, greywater-harvesting, and septic leach field applications since its height does not exceed 12 inches (30 cm), so 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.

Their “Standard EnviroChamber” or “EnviroChamber ProArc Standard Chamber” are their best chambers since their height does not exceed 13 inches (33 cm), so 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. Check out their “EnviroChamber Downspout System Drainage” information for sizing recommendations, while thinking “harvest” rather than “drainage.”
