Water Filtration System
I'm working on a plan for a DIY RV build, and I wanted to incorporate a water filtration system. Specifically, with sustainable boondocking in mind. I'd like to be able to clean any incoming water to ...

There is a low energy and fairly low tech method, sand filters when properly constructed and operated. Not very portable and the effluent still needs chlorine or ozone (high energy requirements). And knowledgeable monitoring.

I've looked into doing a sand filter. It's not impossible to make portable, but still takes up a lot of space (and maintenance). Even went down the rabbit hole researching "Berky" filters to use as the carbon component...but the official claims are just that. "Claims." Berky filtered water still needs to be treated. So filtering non-potable water through a berky system or a repurposed berky filter isn't an option for my goals.

The main drawback of RO systems is waste water. An RO filter will "reject" a lot of water. However, I just plumb the RO waste water back into my RV's water tank.
That's exactly what I was thinking. I'm just not sure if that will cause more damage in the long run. Running all of the waste through the system repeatedly. Causing the maintenance/replacement cycles to be more frequent.
The other thing I want to make clear. There won't be any "human waste" in the gray water. It'll pretty much only be dish water (using some sort of "natural" biodegradable soaps/cleaners).
