I have a 25' shallow 30"id cement-cased dug well that produces 4-5gpm with a soon-to-be installed small submersible pump. I'd like an additional 3-4 gpm without any additional pump.
So my tentative plan is to jet down a 1 1/4" pvc well, then connect this new well with a 1/2" or 3/8" pvc pipe to the old larger well. The idea being that the water level difference between the wells as i draw down the water in the larger well will allow the water to siphon from the small well to the large well.
My water table is about 10 ft down, so the water would need to travel up and then down 10ft +/- a few feet plus, of course, the horizontal distance from the two wells. I could trench several feet from well to well so I might be able to get the vertical drop/fall to more like 7ft. Obviously, I'd need to prime the siphon pipe.
Is this possible do you think? and if it is, any ideas on issues I'm overlooking?
Thanks for any input.
