I used to be a logistics officer for an Infantry battalion. Most of the comments down thread underestimate water consumption. Depending on the climate, you'll want the following daily quantities [1]: - 2-3 gallons for drinking - 1.5 gallons for hygiene (can skip for a while) - 0.5 gallons for food prep The planning factor for military operations was 8 gallons per person per day. Water is heavy—8 pounds per gallon—and…

> 8 gallons per person per day. Water is heavy—8 pounds per gallon The average person needs far less than 65lbs (30kg) of water per day, which is a third of the average male weight in the US. By medical standards humans need more like 8lbs (under 4l) per day for men and 6lbs (under 3l) for women. Less if your rationing and not exerting yourself.

OP’s factoring includes washing, food prep, all that other stuff.

If anyone else was looking for the source of this, it's here: https://emergencyprocedures.pjm.com/ep/pages/dashboard.jsf

Fascinating, if anyone has info on other grids that share these types of alerts, pease link!

PJM is still at "warning". No alerts or actions are listed. If problems were expected, there would be alerts and preparatory actions.

PJM mentions that they turn off guest access if the site overloads. So please don't over-use this link.

The normal amount in disaster preparedness is 1gal per person per day. The problem with the larger amounts is that people see they need huge amounts and don't do anything. Better to get started storing 5-7 gal for each person.

The way to allow for extras is to store water for a longer length of time. If recommended value is two weeks, and it is in my area, then a month is a good buffer.

I've got an assortment of backpacking/camping water filters, but don't live especially near a water source, so my days would revolve around walks to the nearest creek. (2 km away) A cargo bike would help a lot there. If the municipal water is still functional but non-potable, a LifeStraw Max gets you effectively unlimited water on-demand for most sources of contamination.

You could collect rainwater, but realistically water outages are usually not "the taps are dry", but rather "the water treatment plant failed so we can't guarantee the water is safe to drink."

I do collect rainwater! (In the summer months, at least.) Have a system cobbled together based on bluebarrelsystems.com

Though disaster preparedness and water efficiency are a bit at odds. For the former I'd want to keep all my barrels mostly full, but for the latter I want to keep them empty enough that rainfall events aren't overflowing them and wasting water.

Can you really call yourself a prepper if you don’t have a faraday cage with a spare laptop inside? (The intersection of doomerism and tech is amusingly cyberpunk sometimes.) Actually, what’s the most useful way you’d prepare for a worldwide grid outage? This isn’t that, but sometimes I wonder if a future CME might be as catastrophic as some say.

Ignoring unrealistic preparations for most of us (such as bunkers and whatever else), an adequate supply of food and water to handle disruptions to logistics for a realistic amount of time must surely be the lowest hanging fruit (e.g. a month?). This is fairly trivial if you aim for things like rice and pasta, and if the grid goes down for longer than a month a lot of us are dying regardless of how we prepare.

My prep kit is my camping gear

- water purification/iodide tablets - Sawyer mini (life straw works too) to filter the water - rations - camping stove, white gas, waterproof matches, lighter - I may or may not have a firearm and may or may not bring it when me and my non-white partner go camping in eastern Washington/forks .... - Tanked water heater for potable water - fire extinguisher (granted I leave that in the car when camping) - poop bucket - solar panel+back up battery, assuming they survive any issues with the storm. I'm hoping a townhouse has enough barriers to protect against radiation given I keep the camping gear in the basement

I should probably print out some maps of things like resoviors, ports, and other critical infra/services in my area at some point.

Days. After the soviet union fell in Armenia there was no supply of food the first days. Also no gasoline nothing. The first day people were normal. Second day people started stealing. Third day all birds and rats were shot for food. Luckely soon food became a normal thing again. But chaos is quickly there. I believe even quicker in rich western countries. Most men and women cant survive on their own for a week.

You can survive with no food for a week. And you can use water from toilet tank for this week.

Most people have a weeks worth of food in their house. Unless they are people who don't cook.

It is easy to make that longer by keeping extras of stable food they normally eat. I like to keep extras of everything I use regularly. Which really helped during the pandemic.
