Lisa Vargas of I Need That to Prep has written a two part article at American Partisan on how to purify water in a grid down situation. Have safe water to drink is one of the most vital things you need to survive.
Water Purification In A Grid Down Situation – Part 1 (purification)
Water Purification In A Grid Down Situation – Part 2 (filtration)
An excerpt from the second article appears below:
In this post, we will focus on ways to filter water as opposed to ways of purifying water. As you learned in Water Purification in a Grid Down Situation – Part 1 the first article of this series, I posted; purifying water and filtering water are two different things.
If you are stuck in a situation where you don’t have clean water readily available, it is vital to know these various ways to either purify, or at least filter the water so you don’t get extremely sick, or worse.
Filtering water is similar to purifying water except that we are using physical barriers to get rid of dirt and grime in the water as well as bacteria and other microorganisms.
Remember, filtering water will not get rid of as many microorganisms as purifying water, so if you can, always boil the water after you have filtered it for extra protection.
In a survival situation, I’m always a big proponent of talking about the items that we can carry with us. High-quality water filters from a store will ensure that no harmful pathogens or microorganisms are getting into your drinking water.
But sometimes using store-bought, high-quality water filters might not be an option, unless you remembered to include a water filter in your bug out bag.
Meaning, if we are in a grid-down situation, you need to be able to utilize the things you have with you, or you need to be able to find items out in the open that you can use to pre-filter your water.
Using various types of cloth to pre-filter water is going to be your best bet in any survival situation. You can use socks, t-shirts, or anything that is cotton and tightly woven together.
You simply will pass the water through the cloth into another container in order to filter it. This will remove many of the particulates and debris that you don’t want to drink.
One device that makes filtration super easy is the Millbank bag. You can get one at Millbank Bags USA. They have a fantastic video below that shows step-by-step exactly how to use the Millbank bag to filter water.
It’s very simple and easy to use and is a perfect backup just in case something happens with your main water filtration method.
But just in case you don’t have a Millbank bag or something similar, I learned a great trick from an ex-military helicopter pilot that works wonders. He showed me how to take a pair of old jeans, run one pan leg through the other, then use a zip tie to close off the bottom.
In this way, the old pair of jeans acts like a makeshift Millbank bag. You can also use a primitive version of the Millbank bag which essentially is a cloth bag used to make nut milks.
You can add layers of sand and activated charcoal (if you have some in your bug out bag) in the sack to help filter the water. You can learn more about making a homemade charcoal and sand filter here.
Once you’ve filtered your water, don’t forget to boil it if you can to make sure the water is 100% safe to drink…
