A place I look at for heart health info. When looking about I looked at
gardening for the heck of it. :))

"The study concluded that the average per capita greywater generation
rate is 151 Lpcd. Greywater production ranged from 80 to 83% of the
total fresh water consumption and most of the greywater is generated
from showers. Further, 55 to 57% of the greywater generated in a typical
Omani household originated from the shower, 28 to 33% originated from
the kitchen, 6 to 9% originated from laundry, and 5 to 7% originated
from sink, which constitutes approximately 81% of the total fresh water
consumption."

This study aims to evaluate the potential of greywater availability in
Muscat Governorate in the Sultanate of Oman, to establish a methodology
for greywater quantity estimation, to test greywater quality in order to
assess reuse potential, and to examine public acceptance for reuse.Total
fresh water consumption and greywater generation from different
household sources were measured by water meters in five selected
households during summer and winter. Additionally, a survey was designed
and conducted in five administrative areas of Muscat Governorate, with
the objective of testing a methodology for estimating greywater
generation potential in these areas. Collected data were compared with
that used by the Ministry of Housing, Electricity and Water, Sultanate
of Oman. The survey covered a total of 169 houses and 1,365 people.
Greywater samples were collected and analyzed from showers, laundries,
kitchens and sinks in some of these households to determine their water
quality parameters. Statistical analysis results indicated that there is
no significant variance in the total fresh water consumption between
data used by the ministry and those measured and estimated during this
study, highlighting the applicability of the tested method.

The study concluded that the average per capita greywater generation
rate is 151 Lpcd. Greywater production ranged from 80 to 83% of the
total fresh water consumption and most of the greywater is generated
from showers. Further, 55 to 57% of the greywater generated in a typical
Omani household originated from the shower, 28 to 33% originated from
the kitchen, 6 to 9% originated from laundry, and 5 to 7% originated
from sink, which constitutes approximately 81% of the total fresh water
consumption.

The physical, chemical, and biological analyses of the grab samples
revealed that greywater contains significant levels of suspended solids,
inorganic constituents, total organic carbon, chemical and biochemical
oxygen demands, total Coliforms and Escherichia Coliform bacteria. The
public acceptance survey illustrated that approximately 76% of the
respondents accepted the reuse of greywater for gardening, 53% for car
washing and 66% for toilet flushing.

Find the results quite odd regarding toilet use facilities. Most don't have
a toilet, as we know it, in Oman.

Considering all the chemical oddities in laundry detergent, sink/toilet
cleaning chemicals, people cleaning chemicals, and so forth; I would
reconsider that thought about reuse of grey water. Really a smorgasbord of
who knows what. If one can revert to lye soap and herbs for smell, go for
it.
