Catchment Water Pre-Filter

[morganlady]

Unless you divert the "leaves, insects, dead mouse carcass, bird feathers, twigs" that may be part of your roof's runoff, basically, you'll be making tea out of all that stuff, by running fresh water-run-off past over and through it (like weak chicken soup that the chicken run through?).
Try to design a way for that big stuff to be separated above the flow, so you're not decomposing it into your "drinkable water supply". Or use distilled water to drink (from a biology/chemistry/environmental science major)
