The cheapest manual pump method for that deep of an application, would be to put a brass foot valve on lengths of 1/2'' galivized water pipe, and build a lever to move it up and down, this depth is going to create a lot of weight due to the water column and the lengths of pipe. the pvc pump you mentioned wouldn't have the required strength for that depth.Thanks for all the advice! I thought I read an article on a PVC pipe pump some where and now I can't remember where. But yall gave me some great ideas. Thank you!!
A pully rigged over the well
A bucket that will fit down the shaft
550 feet of cable attached to a drum with a hand crank
and a woman to turn the crank!
