Greetings,

I've a septic tank, and fairly hard water. It's my understanding that
the discharge from the cleaning cycle of a water softener is is damaging
to septic tanks (or rather, the bacterial colonies, as well as the
vegetation growing on the leach field).

What are the options for softening the water for the entire house in
this case?

Thanks!

??? Never heard that before. I've had a water softener for 20+ years, and my
septic system has never had a problem.

The only concern (other than by those promoting a "solution") I'm really
aware of is the additional water volume may be a problem for a marginal
system.

Here's a link to a U of MN site that's pretty informative...

dqb,

I presume that Javier fears that the brine that used to recharge the
resin tank may be too salty for the septic system. I don't think that's ever
been the case. He should check the size of his septic tank. As for the leach
field, the softened water that goes through the septic tank and the brine
both contain sodium chloride which may accumulate in the leach field. This
salt eventually gets washed away by rain. I guess it's possible during a
drought for enough salt to build up to stress the grass a bit. Never heard
of this though.

It is the calcuim salts plugging the system they are worried about.
The same crud you are keeping out of your water heater and clothes
will eventually compromise the field ... or so they say.
I just put a long piece of perforated drain pipe in the dirt near my
discharge and piped the WS water there. That system has not failed. I
lot probably depends on how well you "perk"
