Pretty much anything where I am is don't ask / don't tell

I looked up CA Regs on grey water a while ago, and they allow pit draining if constructed properly, it seems pretty easy to do to even be "legal".

Our washing machine is on a separate system than septic but it's temp right now, and uses corrugated drain pipe, once we go 'perm' I'd LOVE to tie my shower, and dish washer into this with the washing machine that would get all the water except the kitchen sink and toilet which is perfect.
