we might consider pasteurization free, if it's done by the water heater,
or with a good heat exchanger. i'm only planning on running rainwater
into the toilet and the water heater.

sure. i seem to recall our boh gang saying 5-10 coliform colonies/100 ml
is ok for drinking, by older standards. then again, these should be mostly
dead, after the heater, and i don't plan on drinking the hot water (or
toilet water :-) btw, that 25 micron ge filter delivers 1.5 gpm with 6'
of head, when new.

i wonder what it is for people.

well yes. sensible people (vs seos and bhos) live by probabilities,
balancing prevention costs with the risks and penalties of mishaps.
