I am pretty sure if you had to get your water from one of these devices you would not be using it to flush toilets or other non-essential use.

And actually it does seem like 'drinking water' is actually drinking water and not for all those other uses you mentioned. As 3.7 litres is the amount required for a human male each day.

Are you suggesting that toilets, showers, washing machines use salt water?

Is there a problem with flushing a toilet with salt water?

Offhand I'd say that you are doubling the plumbing system plus you are using a much more corrosive fluid.

It would be an interesting experiment, since toilets use a great deal of water. Take a beach town, build a separate pressure water and sewer system, see if it's worth it. It's certainly more complicated than a sailboat's set up.

If their toilets used clean water, then I have a much more efficient way to produce clean water : drink from the toilet and shit in a hot house.

From Wikipedia:

> Drinking water, also known as potable water, is water that is safe to drink or use for food preparation.

40-50L per day would seem to about cover one person's essential uses of potable water.
