50 gallons sounds like a lot, but if you are using 2 gallons per day x2 people x 14 days, that's 56 gallons just in showers. I know when we stayed in a little cabin on a muley hunt we went through a lot. It had a developed spring a few hundred yards away we'd fill 5 gallon water containers from. It amazed me how much more water we went through with almost all the niceties of home than we go through when tent camping. The cabin had 12V lights, a sink, grill, stove, just no running water. With that set up we cooked more in the evenings and used more dishes which meant more water to clean them too.
When camping simply you can go on very little water. When you start adding in more dishes, showers, etc. it can be amazing how fast you go through it. Camping near a decent source and having a good filtration method might be a good idea if it's possible.
I'm trying out a new gravity system I rigged up this fall for our truck or UTV camp. I got a Sawyer filter rigged in between two 6.5 gallon water jugs. I wrote CLEAN and DIRTY on them in big marker. I plan to take the dirty water jug along each day in the UTV with a mesh filter/funnel I created and a 10L collapsible bucket. We can strain the water into the dirty jug, then filter it at camp. I have a cleaning kit for the Sawyer and a spare filter as well. We will have a small solar shower and simple cooking set-up but are keeping things to a minimum. Part of the scouting trip will be finding a camp site with a decent water supply close enough to reach with the UTV that won't screw up the hunting. If we can't find that our plan will change. We can do a simpler camp and use much less water.
Getting a quick rinse and then shutting the water off while soaping up, rinsing after can save some water also. Not maybe as nice as a long hot shower but better than nothing and just as effective.
