What is the usefulness or harmfulness of the outflow from septic tanks
for use an fruits and vegetables?
There is no question as to the suitability of the affluent from a septic
tank for irrigation purposes. Waste waters are sometimes injurious when
they are loaded with antiseptics, but the septic tank will not work
unless it has a chance for free fermentation in the absence of
antiseptics, therefore, this objection against waste water does not hold
with the out-flow from septic tanks. It has the advantage over straight
sewage irrigation because fermentation in the septic tank is believed to
free the water from many dangerous germs, though not all of them.
