Dig two and join them 4000 gallons then.
I’ll have to look around and find the site about well digging....
This fellow worked out a fairly simple system for use in Africa to dig shallow wells safely. He used a pair of steel rings that were about 5’ in diameter, that supported long planks that were wedged against the earth all the way around the excavation. It looked big enough for 2 guys max, but it was a very effective technique.
You dig out about 6” under a plank, slip the wedge and drop the plank to the bottom, then go to the next one. You need a hand winch of some sort above to lift out the buckets of dirt, but you keep on going, lowering the planks, rings and wedges until you’re below the water table, then you set a perforated plastic riser, backfill the hole with gravel and then sand, withdrawing the planks and rings as you go. You can cap the top any way you want and the riser is good for a hand pump or several kinds of water pumps.
It was fascinating reading and struck me as an outstanding thing to know how to do...
If I find the link, I’ll start a thread and ping you....
