don't drink toilet water, eh?

for drinking....for years

But it must never be forgotten that recycled water is not acceptable for direct potable use.

In California, we currently have treatment standards and regulatory requirements to ensure the safe use of recycled water. A basic premise of the regulations is that because of the inherent difference between recycled water and potable drinking water, the two must never be mixed together in a drinking water distribution system.

It's just a question then of dilution.

Actually the requirements for effluent from new waste treatment process are often higher than what the raw water being meets. Or so I think I remember reading.

... the effluent from his waste treatment plant is probably as clean or better than many bottled waters (filtered kind or spring)

In order to use dirty water for flush would require a seperate pipe to fill toilet tanks, independent of taps. This would be a great expense for every household.

but there are ways. Might be feasible.

the supplier to furnish separate water supplies for potable and non potable.

Using 'grey water' (my understanding is that is primarily considered shower and bath water) for outside lawn&garden watering is a bit more practical at present perhaps. Of course, in storing the water till needed you have to handle bacteria and mosquito growth.

I have a well.

What I was thinking of was maybe some kind of tank to catch waste water from the sinks, showers, dishwasher, washing machine maybe, etc. and then a pump (or pressure tank) to deliver it to the toilet tank, The regular water feed to the toilet tank would still be there but turned way down, so you'd get diluted waste water when flushing.

I dunno. I'm not a plumber but it seems doable to me. Maybe the pump is the weak point in the idea.

I think the big problem there is (as I understand it) health laws/regulations prohibit any connection between a potable water supply and a nonpotable water supply.

Not even a valve counts as isolation. In industry, if you sometimes use the well (potable)water instead of other source, it has to be done by physically disconnecting one line and hooking up the other.

So while you could drain your grey water to a tank and pump, you couldn't cross connect the lines at all. I'm not sure that if you somehow put two fill valves in the tiolet tank that would suffice, since they spill out into the tank.

bacteries, Mosquitos.. etc. Not to mention Smell?

To get rid of all that.. you end up with clean water (although maybe non drinkable)

again, thinking of the Caribbean, most houses have a cistern that collects rainwater whihc can be used for flushing. You can zap the water with a disinfectant to get rid of the nasties.

Not suggesting anyone drink toilet water, only that other water can be used in the toilet.
