River water to drinking water for RV

Cheaper, smarter or better ways?

I'm trying to keep it KISS and cheap.

Looking to fill my RV with river water and make it safe and palatable. Pump is not an issue, already there to water the grass. The water is nice enough, if I filled your drink with it you probably wouldn't notice, till you died from dysentery.

Actual purification will be sodium hypochlorite aka bleach.

Thinking about running 2 of these housings with 1 micron carbon, then a .5 micron filter. Strictly for taste and sediment. Actual sediment should be minimal, pulling off the end of a dock.

https://smile.amazon.com/Package-150...-1-spons&psc=1

Tank is 46 gallons, probably have to fill every 2-3 weeks. Wait till it gets low, drain the tank and refill.

Add the appropriate amount of bleach, wait, and boom no one . Should be into it less than $200, and I can toss the filters @ the end of the season and start new every summer.

Would be cool if there was a way to add the bleach in line to ensure equal distribution. I failed chemistry, don't know if that's needed. It may "self distribute", what's the word?

Any changes? Different Filters, add a 3rd, etc.

this dude improves on that a bit... I think if you introduce the bleach into the empty tank each time (or nearly empty) the chlorine will diffuse on its own effectively.

When we told you to drink bleach, you know we were kidding right???


I would probably run it through a carbon filter for a house, then uv it with something like this

you don't have to add the bleach as you fill the tank. just measure out how much you need and mix it with a gallon of water, dump it into tank. You just have to wait an hour or two for it to naturally disperse in the water.

Put this in after the sediment filtration. Id use a sediment filter, then charcoal, then UV light

Why filter and make all the water drinkable if 90% of it is going down the toilet or sink? Add a small Reverse Osmosis setup next to the sink and only fill your drinking water from it.

I think you'd come to regret it. All the crudola that you'll pull into your water system will destroy it pretty quickly and when you are in a situation (like selling it) or going to a regular campground, your system will be compromised. Why not keep it nice and fully functional as long as you can...

1 micron filter (real 1 micron rated) and uv should remove anything that will make you sick. $250-$300 for a system that big isn’t bad. Unless you like drinking chlorine. I’m sure you can get a up system cheaper than the fancy one I posted.

That guy is interesting. He's using potable water. I bet he was just getting hard water deposits in his shitty RV shower head. He would also still die of dysentery, since that system does nothing to purify the water.

I thought of building UV into the system and filtering after the pump so any water on the property was safe to drink, but both are a huge waste. I want something robust and simple. IF we eventually build a cabin, I'll revisit the UV. Having a permanent weather tight spot to mount it is a factor.

If I decide that chlorine taste is a issue, I'll add a carbon filter @ the kitchen sink. It has been my experience that if you properly measure the bleach and allow it to off gas the taste is fine.

Big cookpot from the Costco, stick on propane burner. Boil. Pour into tank.

KISS.

https://www.webstaurantstore.com/bac...SABEgK-svD_BwE


Or buy a few cases of water bottles. 45 gallons in 2 weeks, that doesn't even make sense. Drinking a gallon a day is alot even!

UV


Don't bother with Carbon

Carbon is for taste and order created by CL2

UV will kill the Bacteria that will kill you

CL2 can create Trihalomethanes

THAT...will ultimately kill you

1 micron absolute.



and UV.....some ozone critter thing to round it out.


1000 bux to drink river water safely seems cost effective to me.

Because you want to use untreated surface water, you definitely want filters to remove things such as cryptosporidium and giardia. After filtration, you want disinfection, and using bleach is fine.

This makes me want to find out where OP's treatment plant is drawing from and piss off the dock just upstream.

Is a well not practical?
5 gallon jugs filled from home for drinking and use the river water for everything else not practical?

The guy that lived in a van down by the river? He's dead, not sure if I'd trust his advice.

Seriously sounds like some tinfoil hat shit? Don't municipal water treatment facilities use chlorine?

Is it going to take more than 100 years to kill me? Consider my house is on a well, and I'm only using the treated water 3-4 months a year and then rarely for drinking.

Piss away, urine is sterile, hopefully just like you. Yeah, digging a well or hauling 400lbs of water is way simpler than adding some bleach to my tank. Please read your post out loud to yourself before posting.

There's a thread here by a guy driving around Africa in his Jeep. He put a filtration/UV system for his water tank in his Jeep. Here it is:

Thanks

That is actually pretty dope. 1 gpm is slow, but workable. Could likely mount it permanently in RV tank area.

I wasn't clear on this, but until now 100% of this water is going down the drain. We are VERY frugal with water and use bottled for drinking, coffee, and cooking. Showers are rare, we are "camping" and swimming is good enough to rinse the sweat and grime. We use a private porta potty that is serviced weekly. The fam does use the RV toilet @ night if needed. Hauling a case of water for a weekend is no big deal. It's convenient, but wasteful.

We are spending more and more time there and I want to eliminate the bottled water for anything except drinking. I'd be happy if I could make my damn coffee with water from the tap, wash my hands, cleaning, etc.

This seems like a pretty simple solution. I looked @ the UV an discarded it, since I wanted something that didn't require power. After some more thought, I think I may see if there is space to plumb and wire UV in the RV before the tank, and then mount the primary filters @ the spigot. This gives me some added peace of mind anywhere I go. I can simple use a RV inline filter for sediment/ taste on the road.

Looking to see if I can find the inline 12gpm versions that are native 12v to make it simple.

I buy water from town for my place in Colorado. it reeks of bleach, but we just use it for showers and cleaning. but every time we fill up I think damn that's strong.

Thanks, I'm the guy, I got a notification about this thread.

The reason I wanted the filter & UV lamp before the tank was to make sure no nasties would grow in there over time. After almost three years in Africa, nothing has, so I'm really happy with that.

I've changed the filter 3 or 4 times now, other than that, the system has never needed even looking at, and I use it 10 times per day, at least.

Fire away if you have any questions.

Health dept regs in all 50 states require a remnant of chlorine at the end of distribution. That means if you are close to the distribution, you will have a max dose still in there.

The chlorine does not create THMs/THCs. The reaction of chlorine and carbon based materials creates those. The amount of those in your water depend on the limiting reagent in the reaction. Take out all the carbon based things in your water before you chlorinate and the THMs/THCs will be so minimal as to not be a concern. They are a problem for municipalities because they treat with CL2 first to keep their equipment from growing algae during treatment, so they have a ton of carbon based floaties on initial CL2 treatment.

In your case, filter first so minimal floaties. There are other taste/odor issues likely in the river the carbon filter will help with. I'd still use it even though you are adding bleach later.

I'd suggest adding a dose of bleach to your filters and rinsing them after a fill up to prevent algae growth while in storage, then run some on the ground before filling the tank.

since your pulling river water, I'd add a 1/8" opening screen prior to your 5 micron filter (nominal), then a 1 micron absolute.

The setup the dude has in the video is pretty simple and functional so long as you are bleaching the tank. He doesn't mention it, but without that, he's set up for public potable.
