u/HardRightCapn · 70 pointsr/preppers

I've been studying this for a bit. Water storage seems complicated at first, but it's really not.

  1. How much water?

  • FEMA says 1 gal per person per day. I say 2 to account for extra sweating, hot weather and the amount needed for freeze-dried food. Plus other comforts like coffee, tea, etc. A family of 4 for 3 days would be = 2 gal x 4 ppl x 3 days = 24 gallons.

  1. What containers?

  • Most everyone uses plastic. You need Food-grade, BPA-free, HDPE plastic to be safe for long-term storage. If a container meets these requirements, then it's almost always stamped in the plastic. You can get away with non-food grade if you're feeling lucky.

  • Water bottles use a cheaper, thinner plastic that will leach over time, ruining your water. Good to have if you rotate regularly, but not for "set it and forget it"

  1. What size containers?

  1. How to store it?

  • First, make sure it's clean water coming in. Have you tested your tap water? We tested ours and have a water filtration system installed.

  • Storing for extended time requires an additive to keep the water safe. You can use a chlorine mixture to stay safe and save money. Or buy any of the additives available. They all kill bacteria while keeping it safe to drink.

  • Clean your containers out. Then, put the big ones where they will go and fill it. The small ones you can fill then store.

  • Even long-term storage has an expiration date. I've heard that it should be refilled around 10 years.

  • Storage location should be kept around room temperature with no big temperature swings and no direct sunlight. Sun helps things to grow inside the water and helps the tank degrade faster. So, a basement is ideal. Inside a closet is next. Do not store outside where there are temperature swings and sunlight unless you take the necessary precautions.

  1. How to use it?

  • You'll need a way of getting the water out of your storage. Smaller containers can use gravity, but you may have to buy a siphon. Larger containers need a pump and somethign to pump them into. Hand pumps are great but the cheap ones are pone to failure.

  • Have some cups and other containers handy to fill from your main reserve.

  1. Emergency water

  • If you have warning before an emergency then you should clean and fill your tub. Those will hold around 100 gallons. Bonus points if you have a Water Bob.

  • You should also fill some containers in the house. Do you have a large pot, food-grade 5-gallon pails or other containers? Fill them just in case!

u/alphaweiner · 12 pointsr/worldnews

The property I live on has well water that isn’t too great, so we use these reusable 5 gallon water jugs. We fill like 7 at a time and pay $.40 per gallon, so it is less wasteful and much cheaper than disposable single use bottles.

u/josiah_nethery · 12 pointsr/waterniggas

I prefer Pur, and if you're feeling like dropping some money on the big guns, get a Berkey

u/RedeyedRider · 9 pointsr/homeowners

Why do you need a whole home reverse osmosis system? Why not a 3 chambered home filtration unit like this one?

You can get filters for the water line to the fridge. They look like this.

Pretty easy DIY project, but the nicer filters cost much more.

u/Teerlys · 7 pointsr/preppers

That was an interesting look through. I usually enjoy M.D. Creekmore's writing. Not all of the specific products picked were the best options in class, but it still gives the general idea and a great starting point for the guy who asked the question. Not everyone will have the $10,000 to drop all at once, but having a decent view of the big picture can help to cherry pick the areas that matter most as they become affordable.

Two area's that could have been expanded on a bit (though I get that he was trying to keep the list simple to follow)... with food, you can get hundreds of pounds of Rice stored for 30ish years pretty inexpensively. Regardless of what other food preps you have I can't see that not being something that everyone should have on hand. You can stretch that 1300 calories a day into a comfortable 2000 pretty easily just by adding that Rice into the mix.

The second was water and water storage. The Water BOB is great for a short term solution and is relatively inexpensive, but having those 55 gallon water drums both provides an initial water supply as well as a place to keep new incoming water stockpiled for times when water from nature might not be available. Unscented Bleach on hand will keep the water from growing anything unfriendly. I know there was a budget to work within here, but water is arguably the most important element to take into account when prepping.

There are a bajillion other little things to nitpick on of course, but it was a fun look at an overview of stuff to go from zero to more well supplied than the majority of Americans if you had the surplus cash to drop. Especially useful for those that have the excess cash but not the time to invest in really learning on the topic like in the case of the guy who wrote in.

u/XeenRecoil · 6 pointsr/microgrowery

That's a lot of damage on such a young plant.

What soil are you using, is it pre-loaded with fertilizer?

What fertilizer are you using if any, what PPM are you feeding at?

What is the quality of your water, you will have the best results using RO water <40 PPM but anything <200 is acceptable.

Under sink RO system.

The article will help you understand how much you should be feeding your plants, it is slanted towards hydro but the fertilizer PPM is still good for soil.

If you buy it mix up a concentrated batch in a disposable water bottle and use a blunt tip syringe to dispense each time you feed and store the concentrate in the refrigerator between uses.

u/theusernameicreated · 5 pointsr/rutgers

If you guys are really concerned, use a reverse osmosis system. The most common are under sink but there are countertop versions as well. It uses the same method we use in pharma to purify injectable biologics (tangential flow filtration) to filter your water using microfiltration (ultrafiltration with smaller filter pore size used in pharma to eliminate viruses).

To test the water for purity, use a conductivity meter (tds meter). Tap water is typically around 300ppm after filtration, you should get 20ppm.

u/tallcardsfan · 5 pointsr/TinyHouses

I have so many ideas! No idea what the weather is where you live!

To start with .... composting toilet (keep it simple) with outdoor shower .... Provide Berkey or similar for water in kitchen. French ditch drain for sink/shower. Maybe a hot tub or a Japanese soaking tub Have a view? Throw an easel upstairs with skylights and big windows. Put it on Airbnb advertised as rustic artist get away.

Just a few thoughts. Swing / hammock would be nice too.

u/pushdose · 5 pointsr/vegaslocals

15 years here and I still can’t even swallow a glass of tap water. Installed an RO system under my sink with a remineralization stage. The end result is silky soft, slightly alkaline water that is better than bottled waters. Amazon Link

It also has a 1:1 waste ratio which is the highest efficiency on the market, making it eco friendly as well. I have very little plumbing skills and it was not difficult to install at all.

u/LeifCarrotson · 5 pointsr/HomeImprovement

No truth. Get a softener.

It will make getting your dishes clean a lot easier. It will make your dishwasher, hot water heater, and washing machine last longer. It will make your laundry cleaner. It will make your faucets, showerheads, and toilets last longer and stay cleaner. And, it will make getting yourself cleaner easier. I don't notice a difference, but my wife swears her hair is smoother and has less split ends with softened water.

Drain and flush your water heater after you install the softener, because it will degrade the lime scale that's almost certainly built up in the heater and result in a lot of sediment in your tank, causing reduced efficiency and possibly problems if that sediment gets into your appliances.

Also, if you've recently bought or are considering buying the home, stop by your county health department and get a water test kit (less than $20). It will tell you exactly how hard your water is, helping you estimate the size of softener you need.

Don't let silt and sediment that might otherwise just be flushed down the toilet (or, conversely, gum up your shower mixing valve) get plugged up in the softener. Install a whole house water filter to catch the sediment just before the softener, they're stupid cheap and easy to install. The valve-in-head unit gives you a shut-off valve right before the softener, which is handy and makes changing filters a breeze.

The only negative considerations are that the increased sodium carbonate in your water may, if used a lot and without any rainfall, cause alkali soil to develop and cause damage to your plants. For my lawn and garden, it's no big deal because I only use it only when there's a drought, and the normal rainfall does just fine to rinse it away. Similar bad stuff may happen to fish tanks. Also, if you're on a small septic system and run your softener too often compared to how much sewage you send through your pipes (assuming a timer system at $400, volume-metering systems won't have this problem), you may damage the microbes running your septic tank. If you're worried, run the softener output into an open drain or dry well like your sump pump instead of into your septic system.

u/MarFlav · 3 pointsr/kitchener

Just get a sediment pre-filter for your system, it'll extend the life of the reverse osmosis mebrane filter, which I don't see in the pic but you may want to check. They're about $70 new, so membranes are a bit costly to replace every time you have to clean the system.

u/parametrek · 3 pointsr/preppers

Lifestraws are pretty short term. Very low capacity and can't be cleaned to extend their life.

> remove heavy metals

Distillation or reverse osmosis. Maybe some specific chelating agent for specific metals. Not really feasible for most purposes.

> Are there heavy metals in ground water or streams in the central USA

It mostly depends on very local historic industries. The worst of them were superfund sites and have hopefully been cleaned up. But check your area to be safe.

> is there something more I need to prepare for?

Viruses in water aren't that much of a problem in the US. It is more of an issue when untreated human waste is dumped in rivers. So it might be worth worrying about in a major SHTF situation. From my research the most effective way of dealing with them is germicidal UV. Not the little things like a Steripen but the whole house size models. Of course these need good pre-filters because they don't work if the water is cloudy.

For serious long term use I'd consider using Doulton ceramic filter "candles" instead of the Sawyer. They are very popular in the off-grid community. Cleaning them is a lot simpler but gradually wears down the filter.

edit: Lol you can just buy heavy metal water filters on amazon. The "KDF" module appears to do the heavy metals and it uses Copper Zinc Filtration. Wikipedia makes it sound like it is only so-so at doing the job.

u/Evelyn_de_Rothschild · 3 pointsr/conspiracy

Filter and bottle your own water.

u/OracleDBA · 3 pointsr/financialindependence

You really should. Imagine if a hurricane hit you in Philly or if there is a terrorist attack or something.

>What's the best frugal way to do that- get a bunch of gallons?

Save your used plastic or glass bottles of coke/juice/bourbon and fill them with water and put them in a closet.

If you are a water snob like me, this is THE BEST tasting water and is a billion times better than a Brita filter: https://www.amazon.com/Berkey-Filter-Ceramic-Filters-Fluoride/dp/B002RZXY5O

This will filter pretty strage water (like rain water) if it comes down to it.

Good luck! ill answer any follow-up questions you have cause we are best buds

u/cicadawing · 3 pointsr/MontereyBay

We bought a Big Berkey about two years ago because of the water taste and we couldn't be happier. Great investment. Also, as a former Texan, avocados are not cheap here. Costco has the best value. If you can't find any ripe, store them standing with the navel side down in an egg carton. As they ripen, they won't bruise themselves by their own weight. Rent is stupid and vulgar here, for sure.

u/huhthatscool · 3 pointsr/aeroponics

I actually didn't tally up the cost as that wasn't really of a concern to me, but I'll try my best to provide links to the things I bought for this. Feel free to add it up for me!

u/CreamyJustice · 3 pointsr/houston

Little fancier, closer to $300:

https://www.amazon.com/gp/product/B005A3WM6C/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

It's actually pretty easy to install, just make sure you have enough room under the sink for the filter and tank. I wasn't crazy about spending $300 (and annual cost for replacement filters) but I think clean water is worth a little extra. Plus, I got tired of messing around with Brita and Pur pitchers.

u/Maxfjord · 3 pointsr/Survival

In my opinion, this test wasn't conducted in a fully scientific manner.
Some more opinions:

UVC is generally a pretty good system for sterilizing water, but I have not ever seen a Steripen, and it looks a little weak for the job.

Here is an example of a system for your home with RO and UV


^If ^I ^wanted ^to ^repeat ^the ^experiment ^to ^see ^if ^it ^was ^worth ^buying, ^I ^would ^get ^some ^clear ^water- ^something ^like ^you ^would ^find ^in ^on ^a ^hiking ^trail ^and ^think ^"perhaps ^I ^could ^drink ^that." ^I ^definitely ^wouldn't ^ever ^think ^of ^drinking ^from ^a ^mud ^puddle ^or ^a ^mop ^bucket.

If I were to formulate a hypothesis it would go like this:

Given that I have found some water near a spring or a very clean creek or snow-melt, and it is clear in a small container (about 1 cup), it might be possible that Steri-Pen could kill any bacteria or other contaminants that might be in it. Therefore:

  • H 0: There are contaminants in the water.
  • H 1: There are not contaminants in the water.

    I would then test the water on two agar plates. One plate would not have water, one would have water.

    If the dish without water becomes contaminated- then I would start over again. If the 'control' agar didn't get any growth, but the water agar did, then I would disregard H 1.

    Next step-

    I would run the same test with the three agars, or even 6 agar dishes.

  • H 0: The water has contaminants in it.
  • H 1: The water does not have contaminants in it.
  • H 2: The water treated with steri-pen has less contaminants in it than the untreated water.

    Repeat the analysis of the first experiment, then compare the fully contaminated agar dish with the steri-pen dish. Now you can answer the question of H 2. Does it have less contaminants in it?

    Now you need to use your common sense, do you think the Steri-pen treated water is generally reliable enough to use for drinking?

    I live in Thailand, the predominant way of making water drinkable is to use a sediment filter, then a charcoal filter, then a very strong UVC lamp on it. In the five years I have been here, the water has not made me sick... some of the vendor food, on the other hand- whoot! Off to the toilet in a hurry.

This is what I have and it's ultra badass. It'll last about 5 years, I bought a 48oz water bottle I use around the house and travel with. Sometimes I'll fill up a gallon container to put in the fridge for chilled water. The water tastes so clean and I haven't bought a bottle of water in years. All you need is literacy and an adjustable wrench.

u/majesticjg · 2 pointsr/HomeImprovement

Reverse Osmosis gets you very close to "pure." Some people don't like the clean water taste and for them they make RO systems with remineralizers to add-back the missing minerals and/or alkalyinity.

I have this system: https://smile.amazon.com/gp/product/B00HRHHFPW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

APEC is a pretty well-known brand and this is their higher-volume system. I have it plumbed to a drinking water tap, obviously, but also to an instant hot water dispenser and two ice makers. That way I'm not dropping ice cubes into my drink that melt and make it taste bad. Because I was having other devices hooked to it, I wanted the high-output model.

If you want their Rolls Royce model, I think this is it:

At the time I got a killer deal from drs foster smith. It was $50 and the replacement cartridges were on sale. I also use it to make water for my fish tank.

You can find kits that out put more water depending on your needs. I got my kit for space saving reasons.

Actually, it might be close. I'm basing my estimate off those 5-gallon water bottles, like this. Those buckets are also roughly the size of 5-gallon construction buckets, like this.

My very rough estimate would be around 4-5 gallons, which is 33-41 lbs.

Under the counter water filter, but it comes out of the cold water faucet, and you can install it, yourself. Much bigger than it looks in the picture, but much smaller than similar filters.

Combine with cleaning the ice maker really well, even just a wipe down, and it'll help tremendously.

u/abfarrer · 1 pointr/HomeImprovement

I bought a "Frizzlife" filter (the MK99 that good inline and filters all cold to the sink) and I'm pretty happy with the quality both of the water and the connectors. The housing is plastic but the lines are braided, and everything has a solid, quality feel to it. I was mistakenly shipped the separate faucet model at first, and have to say I was impressed be the solid heft of the faucet as everything else I'd looked at in that piece range was cheap chromed plastic. The separate faucet model did have plastic tubing, which is part of the reason I went with the other one. I do lose a bit of pressure/flow but it's really not that bad and I'm so happy to not have a filter pitcher in my fridge!

How bout that Brain Force product that was advertised in the video? do you use that?

They're Choline pills.

Brain force you get 156mg of Choline (2pills) for $30.

Choline Supliment you can get 600mg Choline (2pills) for $19

Its literally cut and re-branded Choline, the products claims are literally the same effects as Choline supplements. You're paying 6x markup for Choline.

The profit margin for the product is between 2-5x. that's why you see 50% off as the deal.

The man's smart and has been running the same business model for over a decade. Making products, and promoting content to sell those products to the viewership. its the old "We have a terrible problem and I have the solution conveniently right here for you for only $19.99" strategy, add in some emotional trigger lines like "protect yourself and your family"

That water filter looks like its a well functioning product when it works, a reverse osmosis machine will still save you in the long run. (for the cost of 2 filter changes for an Alexa pure filtration setup, you can buy a reverse osmosis system and have it run for half a decade.)

NSF Certified Resverse Osmosos Machine $136, filters last a year. $25 filter set. standardized filter sizes through the industry. no brand locked filters.

Reverse osmosis membranes have a pore size of 0.0001 micron. The most cost effective system type if you have water pressure. filters over an order of magnitude better than sand filter systems.

Alexapure Water filtration system $156

Passes all filtering standards for public consumption also has some problems , $90 filters


Big Berkey Stainless Steel Water Filtration System not so great product reviews,
Passes all filtering standards for public consumption with higher reductions than the Alexapure product. $258 , $50 filters

cheaper filters. setup becomes cheaper long-term after 3 filter changes. product also has some problems, but seemingly less


Be smart pedes, you make america great again by using your brain, so buy my product Brain Force

Update. I'd actually recommend this one: https://www.amazon.com/dp/B00CYW3EVO

For most people, this is a pretty sweet setup. 3.5 gallons per hour, 3000 gallons per element (1 year+), holds 2.1 gallons, easy to fill. Looks nice. Comes with 2 filters.
