We decided years ago to carry Bottled Spring Water. This followed our dogs getting ill while we were traveling in our Motorhome and will continue in the '58 Traveler. I do have a point of use RO System in the coach but the water where we typically travel is generally poor. I found that about a gallon/day is good for our drinking needs.
I am still using the original black iron tank in the Traveler so no plans to use it for drinking water.
If you have good city water it should have enough chlorine in it to keep the water for normal trips. If you choose to go that way then drain the tank & refill prior to camping. Otherwise you will need to use chlorine tablets & that doesn't appeal to me.

You will need much less bleach to make water safe to drink than you might think.

Clorox company recommends: "If you have a tank with clear water that you simply want to make sure is safe to drink or use for human contact (hand washing, laundry, etc.), then you can follow the protocol for emergency disinfection of drinking water. In that case, the correct ratio of bleach is ½ teaspoon Clorox® Regular-Bleach per 10 gallons of water (or for a smaller size container, 2 drops per quart). Stir the bleach into the water and let stand 30 minutes. Properly treated water should have a slight chlorine odor—if not, repeat the dosage and let stand an additional 15 minutes.

It depends on how old your tank is, and how it has been treated through the years, especially recently. The advice just posted is good for systems that are in perfect condition. If you want to "shock" the tank and system to ensure that old mold is dealt with, you might want to read the following recent thread:

http://www.airforums.com/forums/f443...er-166378.html

Adding a cup of bleach to the tank and other steps discussed in the thread above, will bring a less-than-perfect tank and system back up to speed. After a couple of hours you will need to flush the system and tank out well.

If you could post additional details, there are likely to be a variety of opinions and advice. Is your tank original from 1958?

Cheers,

Peter

We drink the water from our Airstream tank so, as you might expect, we must make sure it is clean, safe and good tasting. I put a small amount ( 1/4 c or so) of clorox in our tank while on the way home on the last expected day on the road and let it slosh around for awhile. After getting home I flush it through the sink faucets and then open the drain to let it drain from the tank. Next time out I re-fill the tank with fresh water. I sometimes need to add water to the tank while on the road but always taste it first. If it doesn't pass my taste / smell test then no water until it does. We always keep a few bottles of water around just in case. So far this has worked for us.

It really depends on the water you're filing it with.
If the water going in is CG water that tastes bad to begin with there isn't much you can do but filter it either before or after the tank. CAMCO sells a inline filter that you can put on your hose to help filter the water before it goes into the tank and trailer. They also sell bottles of Drinking water freshener, it's a sodium hypochlorite bleach so it doesn't taste as bad as Clorox, it helps keep things from growing in the tank. I add it whenever I fill my tank. Both above are available at most wally worlds.
Another option is to set up a whole house water filter with activated carbon on the water hose feeding the trailer, then when you fill the tank use the hose going through the filter.
At the end of the year fill it with a bunch of water and bleach to shock clean the whole system before draining for winter.

It also depends on the fill hose. It is best to have a hose used only to put water in, and then you drain it and store it in a safe place.

If you are getting that garden hose taste you will work very hard to remove it from your tank.

I keep my water tank full year around. Drain and refill every 30 days. I add a 1/4 of bleach. My trailer stays mostly prepped and ready to go quickly if necessary. All I need are consumables and clothes and I can be on the road in an hour. I keep enough gas on hand to go about 200 miles over what is in the tank. Living in a hurricane prone area my trailer is my escape pod.

I would never drink the water from my tank. I don't drink tap water either. YMMV.

If you regularly add bleach and drink out of your tanks, you should consider at least a good carbon filter at the sink. Adding bleach will kill bacteria, but it can also produce some really nasty disinfection byproducts if there are organics in the water, like trihalomethane (THM) which is a carcinogen.

Same here. We have a Brita for drinking/coffee. I don't mind washing dishes or bodies, or boiling pasta or veggies with it, but I don't drink it.

Question is. Do you want to drink live bugs or dead bugs?
