Going with the bugging in theme, Ive been trying to figure out what will be my source for fresh water. I do have a year round stream in the back yard. However the quality of this water is less than desireable. I do keep 2 55 gallon blue plastic food grade barrels full and change them out yearly. But once that supply is gone then what. Ive read alot on the British Berkefeld or Berkey gravity feed filter system. Great reviews and very simple. Its a 2 piece unit. Fill the top section with your non potable water. It goes through the filters into the lower section which houses your potable drinking water. The filters are not cheap, so in my plan, I will strain the creek water through coffee filters to get the large sediment. Then using several 5 gallon buckets, letting the remaining silt settle to the bottom of the bucket then skim the clear water off to fill the berkey. The Berkey Im looking at is the largest version called the crown Berkey. Its on the right in the photo. It has a capacity of 6 gallons. This should make it easy to dump my 5 gallon buckets in safley. Heres a generic photo of my filtering plan. The pre screened water then goes into the top section of the Berkey which houses the filters. Depending on how many filters are being used, at the minimum of 2 filters the water will take just under 1 hour to filter 5-6 gallons of fresh clear drinkable water. So far Ive sold this idea to the wife. However I thought before purchasing the Berkey I would toss this idea up and see if anyone might have a better idea or have some insight on this system. Your comments are welcomed.
