Actually, a septic system doesn't rely on any sort of bacteria or yeast.
It's much simpler than that. All the waste goes into the 1000 gal
septic tank where much of it liquifies on its own. Solids sink to the
bottom and it just piles up there. The liquid pours out to the leach
field where it evaporates.

Why do you think it is called a Septic Tank? Webster's defines a
septic tank as, "A tank into which sewage is conveyed and where
organic solids remain until decomposed by the action of anaerobic
bacteria." If this didn't occur, you would be pumping the tank every
few weeks.
