I have a cistern that's 15 feet deep, about 10 foot diameter. It's
right near my well, and there were four steel pieces of iron sticking
out of the ground, which was the base for the windmill that once stood
there. The windmill was gone when I bought the farm and an electric
submercible pump was in the well. I cut off those 4 steel pieces
because I was always tripping on them. The well's pressure tank was in
a barn while has collapsed. I had to dig up near the well, and re-route
the pipes into the cistern, where I put my pressure tank, knowing it
would not freeze down there. It works fine, but breaking thru the wall
of that cistern was a huge job. It's all made of rocks mortared
together and the interior was coated with concrete. The rock walls were
at least 2 feet thick.
Anyhow, it's solid as can be, although some of that concrete coating has
falled off on the inside, exposing the rock. There were a few cracks at
the frost line, which I repaired with mortar, to which I added extra
portland cement to make it real strong. My cistern is meant to stay dry
these days. Even after heavy rain, it stays pretty dry, but there is a
little leakage. I have a sump pump in the bottom to make sure it stays
dry. The pressure tank is on top of a couple cinder blocks so it dont
sit in any water, since sump pumps always leave an inch of water in the
bottom. I have a few patio blocks down there to stand on, so I'm not
standing in that inch of water when I do repairs.
My farm was built in the late 1800s, so that cistern is probably at
least 100 years old. I did of course have to build a new cover for it.
The original one was rotted. I built a new one with treated wood, and
covered it with a piece of metal barn steel. It's made so it cant slide
off or move, to prevent anyone (or animals) from falling in.
