I have a really good year round spring that feeds my pond.. I want to start drinking it instead of the municipal water we have.. The only problem is that the head of the spring is across the fence on my neighbors place.. I know that coons opossums and deer come to the spring and I'm sure every once in a while they take a dump after getting a drink of water... My idea is to build a small dam on my side, install a sediment filter and run pvc about 100 yards into a small collection tank.. 30 gallons or so.. My question.. Should I boil this on my fish cooker 5 gallons at a time, or.. Is there a filter made that I can buy that will clean it enough so I don't catch giardia or some other microscopic crap?? Thanks
