splendite 2000s water usage

Interesting question!
Y'know, we used a Splendide (don't remember which model, except it was vented)for nearly three years of full timing, and never gave any consideration to the amount of water it used. We would often run 2 small loads per day.
I kinda figured we would not want to use it without hookups, though. I think it would deplete the fresh water supply, and fill the waste tanks in a short time!
Now, I wish I had paid more attention; my curiosity is aroused!
Hopefully, sombody who knows will have the figures.
