We have lived at our present property for 11 yrs. The water situation is very iffy - our well produces less than 1 gal per minute. With 4 children it can be a challenge but we are all good at conserving. A cistern collects rainwater and that helps too. We may add a pond at some point for a more reliable source. On to my question - we've been buying 5 gal. bottles of drinking water the entire time we've lived here and I shudder to think of the money we've spent that way. What would be a better option? Our water is kind of rusty and slightly sulphury. Every once in a while we have water delivered to our cistern and it's chlorinated city water. The rainwater off the roof isn't real clean, I'm sure. Does anyone use the British Berkey filter on a regular basis? We drink a ton of water so whatever we get would be used hard.
