I is amazing how much water can be saved............ if you have to carry it.
Early on, "The Place" used a sawdust toilet (worked well).....and 5 gal water bottles filled at the local city park, 5 miles away.
Added a "solar shower"....started with the black shower bag, (heavy), to old water heater tank in black box and black hose on roof, circulated with a 12 volt pump.
Ended up with a Zolar propane water heater.....the added a 50 gal drum....then second drum with water catchment for gutters and down spouts.
Propane heater was a PITA as water had to circulate or it would over heat.........so shower may be really hot, to warm to just right....
Added a 2-1/2 gal electric water heater, (yes had electric).....used the 50 gal drums, and sprayer 12 pump.....Hot shower on demand.
Now you spoke of other using it?....Well, many visitors like long hot showers.......we sent tem to town to the park public shower, or truck stop $4 bucks.......
Take as long of shower as you want.....BUT you only have 2-1/2 gal of hot water.
With that 2-1/2 gal of hot water....it was....wet down, shut off.....soap up...shut off, rinse....shut off.
Hair washing was a separate event for those long haired ladies.
The rain water was "soft" and really cleaned....and we didn't have to carry "wash water" any longer.
The state approved well, bury tank, and septic system was in the $11K range....and worth every penny.
