Sounds like you have plans. Keeping bad stuff out of the septic is not easy. Adding to the bacteria is good. I use the mice I take out of traps. Keeping roots out of the leach field is important too.
Look up some tips about putting the input shaft in the freezer overnight and heating the bearing. You have to work pretty fast nut the hot bearing will go on much easier.
Good luck with the new job!
