Securing cable to well pipe

This is important. Cable should be taped or attached ( by plastic ties) to pipe every ten feet. A story about the city well being pulled might illustrate the potential problem that could occur. The well contractor commenced the pull, was up a few feet & cut the first tie---turned out to be only cable tie--- 250 feet of three wire number 8 or 6 cable went down hole!! They got the pump out after considerable difficulty thanks to the previous puller.
