Suppliers of infiltration chambers/leaching chambers/subsurface outlet chambers

Infiltrator Systems, Inc., 6 Business Park Road, P.O. Box 768, Old Saybrook, CT 06475; phone: 800-221-4436; website: www.infiltratorsystems.com. 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.

Hancor. Phone 888-FOR-PIPE (367-7473); website: www.hancor.com. 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.”
