I’m finding that the habits I’ve developed for food handling and dishwashing in decades of camping and backpacking in bear country are serving me well with our RPod. That and living with a septic tank at our house (although it's a lot less "sensitive"). I wipe food off dishes and utensils before putting them in the dish pan. This makes more efficient  use of soap and water too of course. I also readily use paper plates when it’s obvious that I’ll be using a lot of paper (to wipe dishes) and might as well save the water, soap and energy to both heat the water and pump it. In campgrounds there is usually a place to dump dish water. With dispersed camping, in most of our areas it’s completely acceptable both regulations-wise and environmentally to dump dishwater on the ground. I do this well away from where we’re sleeping and also using biodegradable (in soil) soap; and well away from any water sources. I never dump food scraps or greasy/oily anything, anywhere but proper disposal (which does not include the RPod’s black tank). And never on the ground even in really remote locations. To me that is both littering and feeding wildlife, neither of which I want to do. I’ve even been known to skim dishwater with a cotton cloth or paper tower in the “just to be really sure” department. As a side note, I would also never empty our gray water tank on the ground on public lands; besides being against most regs it's completely unnecessary. There's a distinction between dumping a small amount of dishwashing water - as one does when backpacking for example - and an entire tank. In campgrounds it’s obviously rude at best to dump water on the ground so if there’s no designated place for that, I dump it in the RPod toilet so it goes to the black water tank. Even though I’m serious about the topic, it’s not a burden or in any way difficult to do any of this and I do it all very light-heartedly as part of our camping experience. Also - many people tout dumping dishwater and/or food scraps in their campfire pit. I recommend against it since it attracts wildlife into your campsite (which will be someone else's campsite after "you" leave). Hope this helps!
