How much water? I think I have a clue.

[Regular Guy]

After reading and studying I believe I may have a clue on how much water to store as a minimum. I believe that number is one months worth. Here's where I got my thought process from.
There is approximately 4 days of food in stores, less water. So if the box stores are cleaned out and if tap water is unavailable you have to over come that hump. Now, there will be folks on the move for water if supplies are gone. So to avoid conflict and interaction with the mass of survivors over water it better, imo, to lay low. I have a kneejerk guess of two weeks for random disturbances. Therefore the last week of water will be used in setting up a way to accumulate more water.
Therefore by my math for a family of four with 5 gallons per day times 30 that's 150 gallons on hand at a minimum.
What say ZS? This is a question that has bothered me for some time.

I think water is essential, but you should also have ways to make dirty water potable as well. During big winter storms where the water lines would freeze my dad would rather melt snow than use any water reserve.


Also different climates will need different levels of water. Here water is plentiful, so I only store a couple gallons. There is a stream nearby that flows nearly year round that I could get water from if I needed it, and nothing upstream of it to pollute it.

I think the OP is on the right track. We have about 250 gallons. Some in 55 gallon drums and some in 1 gallon containers.

It's also important to be able to collect and purify more water for the long term. There is a thread about using powdered pool chlorine (pool shock). It's very concentrated and it stores well. A $20 investment will purify many years' worth of water - 20,000 gallons will go a long way.

[Cockroach]

I'd say it's a good estimation with some great strategic thinking involved. Well done!

[Teqnikal]

I did some similar thinking and came up with the same result. One month of water for my family is 150 gallons. If after a month of a major event some semblance of order/normaility has not been restored, it's time to bug out. Now I need to get my hands on some 55 gallon drums.

One of the benefits of living in Louisiana is the ready supply of water pretty much anywhere. I live a block from a major river, my holdout location with two wells is on a lake, and you can't 'go five miles down any of the highways in the area without driving over a bridge. Of course there is still the matter of making it safe to drink, but supplies for that take up sooooooo much less storage space than storing water.

[Regular Guy]

One of the points I was trying to make was to avoid contact with others. Security may be an issue. If it is then having a ready supply would be preferable. One thing I can think of as a security risk would be looters or in the case of a pandemic, getting infected. It's not just me I'm worried about but I have a family as well. I have ready access to many sources however there is only so much water you can carry and still be mobile. Im talking worst case. Normally, 7 days would be adequate. Or a environmental disaster that causes the rivers/ streams to become unuseable. Perhaps a pathogen in the water. Also flooding would render water non potable.

I do keep a week or so on hand here. I just don't really see the point in storing more water than that when you're on a property way past the middle of nowhere, with multiple wells and a filtration setup. I'd rather store treatment supplies rather than have multiple drums of water in the cabin and worry about the floor caving in from the weight.

[whisk.e.rebellion]

The mantra I always heard is a gallon per person per day, but that extra gallon for a family of four could be luxurious.

Mines being developed in my garage, concrete floors. This is just my thinking, this is not a set rules by any means.

Yep, water storage can be a challenge, even if you live in a saturated area (like me)! We have storage-storage (but a limited amount since we have a small house), but also have the supplies to make water potable (as a PP mentioned). We also have rainwater collection (right now it's used primarily for gardening, but would do for other uses). For short term emergencies we have a backup generator for the well, with its own dedicated fuel storage--but because it's reliant on gas, that's obviously not a great long term solution. Our well is pretty deep, so hand pumping is not a feasable alternative at this time.

One of the mistakes I made pretty early was only counting drinking water accurately and really lowballing the amount needed for cooking. Looking at that made me adjust my food storage considerably (in the beginning, I mostly stocked backpacker/rehydratable food and grains as the primary stuff I was storing--not a great idea when you're lowballing the water needs to rehydrate/cook!). I didn't expect thinking about water to make that much of an impact on what I store for food but it really altered my plans!

I'm thinking about bathing, dishes and general cooking/cleaning as well.

Very, very true. Bathing is also very nice when the temp reaches 110F. My hideaway location is down miles and miles of half a dozen dirt roads, so there's no traffic. It's also on a lake that some rather uncouth people dump the contents of their houseboat toilets into on occasion. My family and I have planned to treat water accordingly.

This reminds me: I need clean 55gal drums for water!

I currently have water jugs for 35gal of water, which about covers 7 days for our family of 5. Thinking about it, I'd really like 5 or 6 55gal drums of water for long term storage.

[Sckitzo]

Think it's dependent on your area as well.

For me, it might actually be better to have more water then food for example, it's not that food is easy to come by, it's just that water is really hard, we've destroyed the aquifer in my area and as we saw locally last winter, one hard freeze disrupted water to the entire city, gas as well.

My rough number is 1.5 gallons a day, that should leave enough for a whore bath every few days. Right now I just use 2liter soda bottles, starting to get a large collection but once I have some more funds going to grab 3 55g drums for the garage.

[MrMendigo]

Do you have a well, or city water?

[LtCmdLeia]

My rule is, take whatever you think you need and double it. I know the rule is 1 gal per person per day, but no one is used to rationing like that. Face it, we're a water wasteful society, we don't think about how much we're using. I think you'll find you'll need more water than you stored once you have to use it.

QFT...but since we are on a preparedness website we should advocate learning to conserve before we need to conserve.

This needs to be underlined and repeated. We lost our water supply once in recent memory, and flushing the toilet with a bucket of water really opens your eyes to the amount of water you use. That doesn't include any other sanitation needs such as bathing, washing dishes, or going laundry.

One thing that is entirely useful and practical when you are in a water rationing situation is to reuse the water as many times as possible. So you start out washing your hands with it, then you collect the soapy water and use it in your laundry bucket, then you flush the toilet with that.

FYI for those just starting out. Dollar Tree has an endless supply of 1 gallon water containers that are made of the same strong PET material that they make 2 liter soda bottles out of. They're a buck and they'll last for many years. If you don't know where to start, go down and buy a case of 6. It's not the most economical in the long run, but it's a start, for those who have nothing.



Just don't buy the ones that look like regular milk jugs! They will leak.

[Regular Guy]

Well, for flushing I would use unfiltered water from the pond and wet land around my home. There is also a medium sized lake near by that takes me about 5 minutes to get to.
For laundry the lake water would be perfect, it's relatively clean.

Mine is closer to 3 gallons per day in the summer. I had 55 gallon drums in my laundry room for a year and it doesn't have AC. I checked the water after a summer and noticed no change to it. It still had the faint bleach smell after 1 year of storage with summer time temps. Do yo know of this guy? Probably best to have someone with a truck and do a bulk buy and drive them down there, unless you got a local seller.

[LibertyBelle]

I have four square 5 gallon water containers in the house along with some bottled water, a couple of 55 gallon barrels of rainwater just outside, and live water literally just a few feet from the barn (has never gone even close to dry). The 5 gallon containers inside will supply my family for a few days if the power goes out. If we're talking long term, there are methods of water purification at hand to utilize the other sources.

[Omega DR]

My two cents. No one can possibly store enough water for long term usage, beyond a few months at best. Even if you use 3 gallon per person a day, that's over 600 gallons of water of one month. Where is gonna store it? How you gonna move it?

Access to a reliable water source and multiple water purification systems are a better long term plan.

I agree, but I think short term is at least equally important, by all means having a long term plan in vital but not realistic to many and the likely hood of me dipping into my short term water preps is much greater then having to enact my long term ones.

I really think it's a region thing, short term for me is going to have to suffice, finding water in the desert can be a challenge, finding water in the middle of a city in the middle of the desert is going to be damn near impossible, so a migration to a water source will be required, but is not feasible at this point and time.
