Peter there had a great idea Ben. Many if not all toilets are near an exterior wall with some sort of window. Most. It would be easy to set up a 10 gallon tank just outside the or on the other side of the wall to collect rain water and tee it off from the water valve in the toilet. Then you get gravity fed rain water running your toilet.
OK so you use city water in the dry months, but during your rainy season you get free toilet operation.
