Unlike a lot of
ecological stopgap measures, greywater re-use is part of the
fundamental solution to a major ecological problem,
The volume of (useable)
household greywater sent to waste each day is more than sufficient
to irrigate the average suburban garden.
As sub-surface irrigation
only requires 15%
to 25% of the volume used with surface
watering, combining the two elements re-uses water destined to waste
while saving time spent holding a hose.
