Spa-flex greywater hose

One-inch (30-mm) minimum diameter spa-flex PVC hose does not kink and clog like garden hose and works great for above-ground moveable greywater hose. A press-fit adapter bushing/fitting makes the transition from rigid ABS pipe to the spa-flex hose. Hose lengths should be no longer than needed, and the slope should be kept as constant as possible so air and water can drain freely. Spa-flex hose is available in a number of colors.

Greywater leaching chambers (aka, “infiltration chambers” or “subsurface outlet chambers”)

Infiltrator Systems, Inc.
I used to feel the “Quick4 Standard Chamber” was ideal for French-drain, 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. I feel these standard 12-inch tall chambers are much better than the high capacity chambers with heights of 16 to 24 inches, which discharge the water lower in the soil profile, out of the reach of more roots. But now Infiltrator Systems has a new chamber which I think will likely prove better – the Quick4 Plus Standard Low Profile (LP) Chamber. It is only 8 inches (20 cm) tall. So what is discharged through the chamber can infiltrate even higher in the soil profile where there is more life to utilize and filter the water. This chamber has en effective length of 48 inches (122 cm) and a width of 34 inches (86 cm).

Hancor
Their BioDiffuser 11″ StandardStandard EnviroChamber and EnviroChamber ProArc Standard Chamber are their best chambers since their height does not exceed 13 inches (33 cm). The BioDiffuser 11″ Standard is perhaps best since it is the most shallow. 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. Look them up under “On-Site Leaching Chambers.” Check out their “EnviroChamber Downspout System Drainage” information for sizing recommendations, while thinking “harvest” rather than “drainage.”

For plastic 30- or 55-gallon barrels to make your own chambers, check:

Feed stores
Soda- and juice-bottling companies

For plastic 5-gallon buckets to make your own outlet shields, check:
