These criteria are reasonable but not yet proven.
2 The NutriCycle Graywater Flower Bed is part of
the NutriCycle System which also includes composting toilets, and
a permitted plan for landscape use of the compost and liquid
fertilizer.
3 Disclosure that "only NSF approved
composting toilets, low flow fixtures, and no garbage grinder, can
be used on this property," may be appropriate.
4 Rationale for the NutriCycle Graywater Flower
Bed Design Criteria is available from NutriCycle Systems
5 Minimum area requirements (residential) and
minimum set-back distances are generally 75% reduced from the
sewage requirements. This reflects both the hydraulic load
reduction of 50% (no flush toilet, low-flow fixtures, no garbage
grinder), and an additional 50% reduction for low pollutant load
(no human body products, no garbage.
6 Septic conditions are negative to the aerobic
design of the graywater flower bed.
7 The NutriCycle Graywater Flower Bed receives
only domestic washwater, called "graywater", and uses it
to irrigate and fertilize vegetation in the landscape by way of an
irrigation trough. |
