I have a septic tank. I also have 3 water softener units (one is a softner,
one is for iron removal and one is for tannin removal). Each runs on a 3
day cycle so one regenerates each night and flushes all the water into the
drain. I just discoverd that these don't drain into the septic tank but
just into a space in my back yard. I now know the answer to why that area
is always soggy. Unfortunately the area has become a mosquito breeding
ground and we have a 20 x 20 area of the back yard we really can't use.
I am doing renovations now and have the opportunity to re-route these to
feed into my septic tank. My question is whether or not this is a bad thing
for the septic tank? It is all water and no solid, but don't know enough
about the details of septic to know for sure.
Alan -- there are a lot of variables and I'm not a professional in this
field, but let me make a few suggestions:
--Your system sounds a lot like mine, located in Central Florida. If you're
in a similar location, there should be some way to minimize the soggy
area -- perhaps with a slight change in grade, digging a dry well, or simply
using the area for a garden with plants that like this environment.
-- If your soil is as sandy as mine, it should drain pretty quickly.
-- Have you considered having all three units cycle on the same day, which
gives three days for the area to dry out?
-- Are you sure you need to recycle this frequently? I have mine recycling
on 4 days and six days, which is adequate. Especially for the
tannin-removal (a potassium permanganate unit?) you should be able to go six
days or more before needing recycling.
-- If you don't have one already, consider adding a hose bib that draws
water before it goes into the tanks, so that water you use for pressure
washing, washing cars, watering the lawn, etc. doesn't deplete your
-- My personal preference is to not send water to the septic tank that
doesn't need treatment.
Thanks for the advice. The soil has a lot of clay and I can't really change
I will probably look at a dry well come spring then.
The guys that did the install suggested once every 3 days. The iron and
tannin I have is pretty heavy.
All my outside taps come straight from the well so I am good there.
It depends on how big your septic system is.. If the tank
is comfortable with the added through-put, and the leechfield
can handle the water volume, you're not likely to poison
the septic tank. But a separate drywell is still a better idea.
Short-term, unless you got a really cheap-ass system, or the effluent
from the water purification is a big fraction of your total wastewater
output, the salt load shouldn't be a significant issue. If it was,
you'd have already killed the grass where you're dumping it now.
