offgrid drinking water filtration

Awesome video, just watched the entire thing. Very easy to follow. Here are my notes

Four barrels.
1) big rocks coarse filter
2) gravel + sand + screen
3) charcoal
4) clean water storage tank

notes: clean the charcoal and sand with water until minimal dark effluent. high temperature fire can render clean charcoal from wood with little smoke.

Connect inlet source near bottom of first barrel, attached to balloon actuated fill valve. First barrel overflows into second barrel. Second barrel flows out from bottom and up 4/5th height to third barrel. Third barrel flows out from bottom and up 3/5th height to holding tank.

Great video and really cool to see the entire thing explained so straightforwardly.

Replace charcoal every 2-3yr. Backwash first barrel occasionally to remove silt. Stir second barrel if clay accumulation slows flow
