Homemade Berkey Water Filter

This article will guide you through the construction of a filter equivalent in performance to the Imperial Berkey that sells for about $300. My total cost was $122

Gather the necessary components. You will need the following:

  • two 5-gallon food grade buckets (got mine from Lowes for $5 each)
  • two lids for the buckets (got mine from Lowes for $1.50 each)
  • a pair of Black Berkey filter elements (ordered mine on Ebay for $99 which included free shipping and a free Sport Berkey filtered bottle)
  • a food grade spigot (the kind used for large coffee pots or water coolers is perfect, ordered mine from jamesfilter.com for $10)

Drill two 1/2″ holes in the bottom of the upper bucket and two matching holes in the lid of the lower bucket.

Drill a 3/4″ hole in the side of the lower bucket toward the bottom. Make sure that the hole is up just far enough for the spigot to clear when the filter is sitting on a flat surface

Assemble the lower bucket by installing the spigot and the lid with holes.

Install the filter elements in the upper bucket through the holes in the bottom.

Assemble the filter by placing the upper bucket on the lower. Be sure to line up the holes so the tubes extend through the lid of the lower bucket. Place the remaining lid on top.

To use the filter, fill the upper bucket with water and wait. If you are starting with dry elements, it will take quite a while before the water starts dripping into the lower bucket. It takes up to several hours for the clean water to drain into the lower bucket. This process can be sped up considerably by frequently topping off the water in the upper bucket. This maintains maximum pressure on the elements.

Notes:

  • I had no scientific way to test the water quality; however, the filtered water was clear, had no odor, and tasted similar to distilled.
  • The specifications of the Black Berkey elements can be found here: http://berkeywater.com/BerkeyLight/BB_Purification_Elements.html
  • There are a number of ways to make this even cheaper: Use free buckets from a grocery store bakery or restaurant. I have found the same type of spigot for $5 since making this one. Super Sterasyl elements can be substituted for the Black Berkey elements. They cost about $84 a pair.
  • The filter can be made considerably larger by using any two stacking containers suitable for water, trash cans or 30-gallon water barrels for instance. The flow rate can also be increased by adding more filter elements.
  • The filtered solids remain on the outside of the filter elements and will eventually interfere with the rate of flow. Therefore, it is important to prefilter through a dense cloth (we use cloth diapers) if your source water is particularly cloudy. The elements can be scrubbed clean with a plastic scouring pad. The Black Berkey elements last for about 3000 gallons each (6000 gallons for the pair)

    To save even more money, one can replace the filter with natural products such as sterilized sand black Charcoal [never brickets] other porous materials such as grasses. Not the very best, but will do in a pinch.
    Simply fill the top bucket with 1/3 purified sand, 1/3 Grasses and 1/3 Charcoal on top.

    I use a Berkey water filter now. I wish I had found this article earlier could have saved a couple of hundred bucks. I had an idea that you could also use 55 gallon drums with the same set up. Seems like a lot of fly by night dealers for the berkey out there. Here is a reputable place to shop for a Berkey Water Filter . You can find them on Ebay, but try getting ahold of someone if something goes wrong.

    My only concern with this setup is the fact that it's using plastic. I didn't purchase the berkey light for this very reason even thought they state it's BPA free. I can't imagine this plastic is any better, but I could always store the filtered water in glass to save a couple hundred bucks. I was going to order a Royal berkey water filter because the Imperials are out of stock, but this solution is worth giving some thought.

    A couple of inexpensive aluminum (or stainless steel if you insist) stock pots would be perfect for this. I would like to first filter through layers of sand and activated charcoal, possibly even boil first if water source is really suspect (floodwater). But I'm paranoid. what's your excuse? : )

    Hey everybody, just wanted to let you know that I found a good source for the parts and all the Black Berkey elements online. Check out http://www.berkeyproducts.com . They have great prices and excellent service. They all seem to have similar prices on the systems, but these were the best prices on the parts and elements.

    Save yourself some money and get a complete Do It yourself System for under $30.00 at the following website http://www.emergency-h2o.com/index.html
    I have ordered for my kids to put in the survival kits. They recommend that you use a food grade bucket but when times are real tough I think anything even a trash can that has been thoroughly cleaned can be used. Hope it is of benefit to all to visit this site. It has some real good information and a CNN link showing the filter in action.

    Scary to think that times could get tough enough to require this.

    In a survival situation I think this solution is awesome! Thank you for the detailed pictures as well. I definitely think the black berkey water filter is the best one out there.

    In a 5-gallon bucket I would probably want to use four filters though.

    You can get a fully configured Bucket Berkey at DisasterStuff.com for $73.50 and you don't have to do anything but screw it together. Pretty good deal and it has the spin top buckets so the top chamber won't tip over. You can get it with 1, 2, 3, or 4 Black Berkey water filters. Go to DisasterStuff.com and then choose Berkey Water filters. Then scroll down to the Bucket Berkey.

    If you hook up a rubber hose like for an aquarium air bubbler to the bottom of the filter, it will increase the flow rate. Seperate your top chamber from the bottom chamber by several feet and it'll be 3-4 times faster in filtering the water.

    That was so cool. It looked simple to make. This would be great to take with my family and I when we go CAMPING!! We could have healthy clean water. Thanks

    If you have been in the market for some type of portable water filter, then you have undoubtedly heard about Berkey filters. These are considered to be the leading high-quality water filters in the world because they are able to take virtually any outside water source and quickly turn it into pure, good tasting, drinkable water. But, in order for the water to always be safe, you will need to utilize replacement black Berkey filters from time to time.

    This is such a great idea for people who want a Berkey but can’t fit it into their budget. I’ve also seen people make them out of stainless steel stockpots – not as easy as the plastic pails, but an option for those who prefer metal.

    Easy to do but rather than use a Berkey Filter I would use the Water Pure Technologies Gravity Flow Nano Filter it’s US made and the filter was co-developed by NASA for use on the space shuttle.

    Has EPA certified lab testing with 99.9999% reduction of virus at fast flow rates and the filter will produce up to 25 times more water before it needs to be replaced and the flow is over 100 times faster!

    They don’t have them listed online, primarily been used by Humanitarian groups but they will sell them to you if you call them. $50.00 you’do spend $2,000 + on Berkey filters to get the same amount of water
