Another idea for sanitizing fresh water tank

I know this is a suject that's been discussed many times already, but I thought I would share a method I recently used to sanitize my fresh water tank.

I know that a lot of folks only use their fresh water supply for showering, washing dishes and maybe cooking when the water is going to be boiled. Bottled water seems to be the popular choice for drinking. I'm ok with bottled water for drinking, but most of the time camping, water is not usually the beverage of choice by our group. On our last trip though, I wanted to have 90 gallons of pure, safe water, so I decided to sanitize the fresh water tank, using a quat based sanitizer. Quat sanitizers are very commonly used in the food service industry and are making their way into day care as well, because of the improved safety and longer shelf life over bleach. I know this, because it's one of the products I sell for a living. What I used was a concentrated sanitizer that dilutes at 512 to 1. It's designed to be used in a dispenser that blends the solution and water together at the proper dilution ratio, by use of metering tips. Quat tablets or liquid sanitizer for commercial kitchen sinks will work as well, as long as you can determine the dilution ratio. Knowing that my water tank holds 90 gallons, or 11520 ounces, I knew that the proper amount of quat would be 22.5 ounces for a full tank. 11,520 divided by 512. Since I only wanted to fill the tank with a sanitizing solution 3/4 of the way, I multiplied 22.5 by .75 to get 16.75. I poured 16 ounces of quat into a garden hose with a funnel, then attached the hose to the fill connector and filled the tank 3/4 full. Estimated of course, by the dummy lights. This quat sanitizer has a 10 minute dwell time to kill everything on it's efficacy chart. I ran it through all faucets, including the filter for the kitchen sink. Then drove around my neighborhood for 20 minutes or so. I drained the tank, filled it again to flush out the pink solution, ran the faucets again, then did the final fill with a filter, for the water we would use for our camping trip. (no hook ups) I taste tested the water afterwards and it tasted as water should, tasteless. The dog drank the water all weekend, with no problems and we cooked with it several times and drank a little of it. No one got montazuma's revenge from the water, included our cute little shelty, Colby.

Just thought I'd share. Cheers!

Richard, I'm not sure since I didn't pay for mine. We're switching chemical vendors and have a lot of our old sanitizer to get rid of of. Check with a local restaruant supply place. They'll have sanitizer for a kitchen 3 compartment sink that's set up for wash, rinse, sanitize. Another place to check might be smart and final or similar.

I wouldn't recommend a quat of any type, they are very slow acting. Most industrial food plants will use a proprietary iodide solution. For a fresh water tank use chlorine in the form of liquid bleach. If it has been years use 15 to 20 ppm for a couple hours then drain the tank and system. If you are in a hurry you can use a higher concentration. Once you refill your freshwater tank use a swimming pool chorine test kit to make sure you are not above 1 to 2 ppm. This is how your park is treating their water, it works. Actually this is what your city uses too. Make sure to flush the hose you use to fill the tank with fresh water before use and drain after use and then attach both ends of the hose together to keep it clean. Chlorox bleach uses a proprietary stabilizer so it is a pretty good brand to use.

Some quats are quaternary amines, do not mix with chlorine, it is toxic.
