Correction. There is a very serious valve between your food and the sewer. The sink trap. Without it, very few people would consider going into the kitchen, much less putting food anywhere near the sink.

The difference in the examples being given is that they overlook the traps and the water in question is on its way out. The fresh water we are talking about is on its way into the system, where it may cook for a few days or weeks. I always make sure we have had a couple of showers with shore water before allowing any into the tank. We keep the pump on for FHU showers to improve pressure and dump the old tank water so we can leave the campground with a fresh tank.

Staph is tough, 'tis true.

But it's far more dangerous to enter a Government Office. There you risk a staff infection, and there's no known cure for that!

If you ever watch folks at full hookup sites you'd be surprised by the slopping and uncleanliness, especially when trying to clean out their sewer hose after use.

By the way, if you dump your gray after the black then your hose is clean. You're not going to disinfect it by holding it under the fresh water faucet!

We'll take a dedicated dump station over a full hookup.

The only things waste related are the dump valves and black tank rinse hose connection. The valves are down low and the fresh water stuff is up high. I store my fresh water hose in the bay next to the wet bay. I only keep waste tank stuff stored in the wet bay. The dump hose goes straight down from the valve and through the floor of this bay.

The furnace is ducted into this section of my basement, so the associated plumbing and tanks don't freeze during cold weather.

If you separate the two systems, you waste another bay and have to duct heat into an additional bay for cold weather use.

I have camped down into the teens and everything stayed freeze-free. I even dumped the tanks and filled the fresh water tank during this cold weather trip.
You have some very interesting ideas.

PM me with an email address and I'd be pleased to send them to anyone

Got the pictures from virago man. Thank you so much both of you. I appreciate the help in making this better!!!!

This accelerates wear, and makes future repair much more difficult. I also have plumbed my coach fresh water system directly to my black tank flush (granted, through three valves and a vacuum breaker) to make use easier and less drippy in the compartment.

If that grosses some of you out, sorry about that. Take a look at my forum handle. That's not just cute, that's because i raised them for a living. Ya' just haven't lived until you have to climb into an 80,000 gal liquid manure tank to free a pump clog. Skin washes. Lol

I don't see it as a problem. As close as they are, the two don't cross paths if you do it right. In mine even if you had a little black tank leakage when you pull off the hose and put on the cap, it's still not going to get in or near your fresh water tank. Keep a can of lysol or some other type of disinfectant cleaner handy if you are really worried.

Does anyone regularly add disinfectant to the freshwater tank? If so, what and how much?

I don't worry much about having them in the same compartment except... In our Discovery, the black tank flush inlet is located directly above the freshwater inlet. After dumping the black tank we flush for a few minutes to try to keep the tank 'clean' and the sensors working. After the black we dump the gray, fairly standard procedure. The problem is that when we remove the black tank flush hose, about 2/3 cup of water flows back out, right over the freshwater inlet. Now I know there is a check valve in the system and I'm relatively certain the water flowing out is as clean as when it went in...but it still bothers me.

I understand the OP's concern (I worked as EMT part time for a few years). It is a real concern. That said, it seems her main concern is the proximity of the fresh inlet and the black outlet being in the same compartment.
Not a bad idea to mist the wet bay with a diluted bleach solution. I also wash the entire wet bay down on occasion if I have the time just make to make it 'cleaner' looking.
The infection control in our hospital could and do make you aware of how nasty some bugs can be and hard to get rid of.

Maybe I am the only freak. But I don't drink any water from the storage tank. Bottled water only for me. I don't full time, so my consumption isn't as great as if I were. I'm not as careful as I could be with filling and how long the water is stored. Regular garden hose and may stay in there for weeks. I even avoid it for brushing my teeth.

I see nothing wrong with your thoughts on this. My husband and I do not drink from the tanks but we do brush our teeth from them. We carry around 5 gallon culligan bottles with a pumper. Several people we have met on the road though feel that the filter and the refrigerator filter double filter the water and that it is okay. if these are 99.9% filters I don't see why that wouldn't be okay if you were emptying and refilling the tank frequently. My husband also puts a little chlorine in the water when he fills up the tank, we used to have a spring and you regularly dumped half a cup in the spring tank to keep it decontaminated from any seeping ground water. Good post. Thank you.
