Yes, a high salt diet into the septic system will harm the flora and fauna...

no good answer, nothing natural about keeping water based liquids from freezing.

An external heating method coupled with proper insulation would be the eventual design goal.

happy coaching!

This would all be a lot easier if I was south of SLC.  j

BTDT.  FWIW we used to let our waste tanks freeze up on our way home from Mexico usually in Feb or early March.  They would thaw out again in spring and we never had any damage but don't send me the bill if something bad happens to yours.  We would never have had more than a couple inches of "stuff" on the bottom of each tank and I always completely winterized the fresh water systems.  But like I said, YMMV and don't bother sending me the bill if it doesn't work out.

  Be careful what your calling salt and ice-melt. Rock salt is same as table salt, Sodium Chloride, that wont really hurt anything, water softeners use a lot and it doesn't seem to do a lot of harm to septic systems. Saying that though, no one uses water softeners down here and you never hear of bad septics. But at its highest ratio it wont stay liquid below zero F.

  Then you have Calcium Chloride. I dont know how cold it can go, way below -30 F, but it is highly corrosive. Thats the crud they spread on roads that eats cars and bridges. And everything else. You do not want that stuff in a septic system, at least not your own.

  Ice Melt, the brand name stuff, is Calcium Chloride. But be careful buying other stuff and always look for the ingredients. I bought a sack of what I "thought" was ice melt, and it instantly started eating our concrete step and sidewalk. Snapping, popping, fizzing and smoking! Made in China, lol, we cant even make our own dang ice melt crud??? And the bag did NOT have the ingredients listed, I dont know what it was. But I had to get the hose out and rinse it off in freezing rain, what a mess. It left 100's of pock marks all over the step, very destructive.
