That's a common sight if you go boating in the Bahamas or Caribbean.
At 50 cents a gallon in some locations it can cost us over $100 to
fill up. That's still a lot cheaper than making your own however.

I assume you have an RO, how much does it cost to make water.

We have tankage for 500 gallons so have never felt the need for a
water maker (RO). They cost upwards of $5 to $7K to buy and install,
take up valuable engine room space, and require a lot of
TLC/maintenance. In addition you need to run the generator which has
a fully loaded cost of $8 to $10 per hour. Assuming a 20 gph water
maker, you're looking at a fully loaded cost in the 70 to 90 cents per
gallon range depending on how you depreciate/amortize the purchase
price.

I was never sure why it should cost that much. I guess running RO from
sea water is tougher than brackish well water.
Basically you just need a high pressure pump and a membrane/vessel for
that along with intake and polishing filters.
Since you are not really pumping that much water, I suppose it could
run off the house battery.
I built one that would make drinking water out of river water and it
ran off of 12vdc. I never actually had to use it and the parts are out
in the shed. It would fill the bladder tank in a few hours tho.
You are not taking showers but it would provide drinking water for a
couple people.
It was a 65 PSI rated chemical pump and the "under sink" R/O setup.
I had a small bladder tank on the input and a bigger one on the
out\put with a precharge of about 20PSI.


One of the houses we had in Florida had a couple of small RO systems,
one in the kitchen for drinking water and another larger system outside
that was used primarily for final rinsing of cars when washing them.
Neither had pumps ... they operated off the house water supply pressure
generated by the well pump.

The well water in Florida (at least where we were) was horrible. Every
house had an elaborate water treatment system consisting of big charcoal
filters and other tanks that did some kind of chemical processing of the
well water. Even with all the processing the water still had a slight
sulfuric smell to it. We never drank it, nor did we use the RO water
for drinking. The RO systems got rid of any funny smell and all the
minerals that left spots on the cars but it had a weird, tasteless taste
if there is such a thing. Everyone in the community used delivered
bottle water for cooking and drinking.
