How to Filter Water Even When It’s Swampy: 7 Ways to Drink Clean Water

Water is essential for life, and we all know that.

But what if there is an emergency and your water source is a swamp? It’s not as simple as just drinking it straight from the source – you need to filter it first!

“How will I get clean water if my city is facing a disaster?”

This article will cover seven different ways on how to filter water, so you can drink even swamp water safely and with confidence.

The Most Effective DIY Method to Filter Even Swamp Water – Sand Charcoal Filter

Clean drinking water is one of the most valuable resources you could get your hands on. You won’t last very long without it. Even if there is no disaster, the current situation is not that bright. That’s because ocean water is not safe and clean now.

The good news is that it can be changed! Thanks to enthusiasts like Lenka Petráková that has developed an amazing revolutionary concept of the 8th continent (a floating station) for collecting and recycling plastic from the ocean.

Now, I’d like to share with you the DIY water filter method that is simple and most effective (according to my own experience).

Step 1 – Start by Collecting Water from the Source

You can use any type of container you have, but make sure it’s clean. Make sure you disinfect it properly before you use it.

Here’s one more important thing. Make sure you have your hands clean and disinfected before you start collecting the water. Use soap and water or hand sanitizer to clean your hands.

The next thing you’d like to do is to choose the spot where you are going to collect your water. It’s a good idea to seek

  • a location as far as feasible from established campsites, which might be occupied by other people.
  • a spot on higher elevations
  • a spot that is not near animal grazing areas
  • a spot with moving water in streams or rivers.

Once you find a proper source put a bottle into the water and fill it out with water.

Step 2: Boil Your Water for 1 Minute or More in a Pot With a Lid

This is critical as you do not want contaminated, bacteria-infested water getting into your system! You can boil it directly in a pot or use another container that can withstand the heat.

Remember to boil your water for at least one minute, but ideally 3 minutes. This is enough time kill bacteria and other microorganisms, but not so much as to waste gas/propane if you are using this fuel source.

Step 2

If possible, let it cool down naturally before drinking or pouring into your personal water bottle (if it’s made of plastic).

Step 3: Add Chlorine or Iodine Tablets to Your Water

After boiling the water, you’ll need to add chlorine or iodine tablets to disinfect your water. Follow manufacturer instructions on how many tablets you should add per gallon of fresh water.(The average city tap has about 150ppm which is safe for drinking while 50ppm is strong enough to disinfect water. However, if you’re collecting water outdoors, double the dosage.)

If you don’t have access to fresh drinking water, best thing you can do is get yourself some Survival Water Filters so the next time something like this happens (unfortunately, these disasters tend to happen more than we want them to), you’ll be prepared!

Next, filter the water in one way or another until it looks clear and free of debris (you may need to change containers). Finally, disinfect the filtered water by adding chlorine bleach if possible; otherwise- purify with tablets or drops. The safest method is boiling for five minutes because it kills all microorganisms.

That’s it! You now know how to purify water in 3 steps. Remember that no matter what you do, never drink urine or sea water as this will further dehydrate your body and increase your chances of getting sick.

There are also some great DIY methods that work just as well!

Other DIY Water Filtering Methods That You May Like

What is the best way to filter water? It depends on your budget, environment, and of course, the amount of effort that you’d like to invest.

In this section, I’d like to share with you 6 more DIY water filtering methods that can work like a charm if you do everything in the right way.


Boiling is a good option since not only does it kill bacteria and viruses, but it’s easy enough to do when camping outdoors.

Boil water for at least 1 minute to make it safe to drink. Boil water for 3 minutes if you’re at an elevation above 6,500 feet (1,981 meters). It’s highly recommended you boil water once it is filtered.

In the event of a local boil water advisory, experts recommend people boil their water to prevent infectious diseases.

Tablets or Drops

Water purification drops and tablets can be also a good way of disinfecting and purifying the water. Here are some of the most widely used water purification drops & tablets

  • iodine
  • chlorine dioxide
  • tetraglycine hydroperiodide
  • sodium dichloroisocyanurate

Make sure to follow all the instructions that you can find on the package carefully. They are easy to use. You need to drop them into the water and wait.

UV Treatment

Another option is to use UV treatment; this method uses UV rays from the sun, which kills bacteria and viruses with no chemical residue.

If you’d like to speed up the process a little bit, just add some lime juice into the water.

Activated Charcoal

Another simple solution involves filtering through charcoal which traps toxins like arsenic and heavy metals into small granules so they don’t get into your body.

However, this method is not good for removing viruses, bacteria, or hard water minerals.

You can also make your own activated charcoal filter- all you need is a container like a water bottle (make sure it’s clean!), sand or gravel for filtration, coconut husk fiber/charcoal powder for filtering out toxins and chemicals, and cloth as an optional final layer of protection against debris.

Travel-Size Sediment Filters

And if traveling somewhere where there isn’t any natural fresh water available yet you want to drink some anyway- try these portable sediment filters!

  • hand-pump machine
  • squeezable pouch filters
  • filtering water pitcher
  • filtering water bottle or straw

They work by blocking particles larger than 15 microns without creating wastewater since they don’t contain any harsh chemicals or iodine additives. These small lightweight filters are also durable enough to filter more than 700 gallons of water, which is way better than other small filters that only last for 50-100 gallons.

Fruit Peel Filters

Another option if you’re really in a pinch or don’t have anything else available is fruit peels! They contain tannins and fibers that bind with the toxins suspend them so they can be washed away when boiled. Just make sure not to use any part of the peel that’s been exposed directly to the sun (that will actually cause it to become toxic).

So simply cut out all areas where sunlight has hit directly onto your orange peels, lemon peels, etc., then boil until reduced by half before drinking up!


Of course, there are many different ways on how to filter water, but these are the most common and effective ones. DIY Sand Charcoal Filter is my top pick.

The best thing you can do is know how to filter water when in nature or somewhere where clean drinking water isn’t available because it’s an essential survival skill!
