Filling in an old water well

[peakbagger]

Call any concrete supplier and get a price for flowable fill. Its a very lean concrete. It gets delivered in a truck like concrete and fills in all the voids. It sets up enough that it cant be dug with a hand shovel but can be dug with a backhoe. I have used it to fill old an old pipeline so it wouldn't collapse and recently had about 500 yards placed under a foundation for small power plant.

The flo fill is a good idea. You can figure up how many yards you need pretty easy: Multiply depth x width x height in feet and then divide by 27, that gives you cubic yards.

What is your cistern made of? Stone and mortar? Concrete? Fiberglass? Just asking because you could get a bid from a local guy with a back hoe to cave it in or dig it out and fill it in with good sized rip rap as another option.

Google Dirty Jobs mine plugging. We use foam like that at work for setting utility poles, it's strong stuff.
