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.

How a softener works...
The discharge from a water softener is discharging minerals that cause hard
water, like calcium and other minerals that your water report should have listed
as hard water culprits and some iron. The salt water comes out of your taps,
which is already going into your septic tank.
