Did this up in sketch up this morning. The objects were premade from 3dwarehouse.

Two sediment filters, two black berkey filters, a shutoff valve, a float valve, a water tank and I have clean water to drink.
Pour yucky water into the top bucket, it filters into the two sediment filters, A float valve in the bottom bucket fills it without overflowing, That water is filtered through the two black berkey filters and flows into the water tank. A 12v pump sends it to my sink for drinking, washing and cooking.

I should mention that my pond water has a lot of swimming things in it, so I will use a fine screen and two buckets to retrieve water. I will be able to process two 5 gallon buckets at a time. Bye bad farm chemicals, bad virus, and yes even the little swimmers will be saved and returned to the pond. No more buying bottled water.

I didn’t win apparently it is fashionable to drink black water. Fads, works out to 60 cents an ounce. $10 dollars per bottle, $229 per case. Ridiculous.

I think I will stick with clean water.

I will do the costing later on I have a door to build right now. Or maybe I am going to retrieve the Geck.

Finally, I ordered my Berkey filters, and float valves, it was cheaper to order two floats and if I ever got to a pressurized system I  could use them. Total cost for those items, with tax $178 CAD.  I sourced food grade buckets and lids four of them under $40 In Grande Prairie Home depot.
4 each at homehardware. Amazon wanted $24 per bucket, without lids. Four hours of driving. If they are in stock when I need groceries I will make the trip in and shop at Costco when I am there. Maybe even source out the rest of the parts.
