As simple as filling a barrel with it and processing your water through it however you see fit.
You can make it all yourself if so inclined, and you seem like an inclined person .
You can also order it for cheap, in bulk.
Filtration as in safe to drink(bacteria being our biggest concern)?
Bleach or chlorine is the cheapest and easiest when talking off grid, if we leave boiling it out.
UV treatment is a option, but when you are talking bulk water, you better have a big UV light and lots of batteries, or have a way to run it off generator power until you run out of gas, in which case your right back where you started.
Distillation is another option but you better have a pretty good size set-up when talking large group.
Have a way to generate pressure, RO works as well, but I don't know anyone running RO in a off-grid situation.
