Not what I regard as hydrovacing. What you do is wash pipe, suck out the occasional sump full of drilling mud during or after the have bored under a sensitive environmental area or under existing gas or oil gas lines or in the case like today wash trucks that are incased in mud from driving on roads that are nothing but mud, better known as dinosaur shit.

This primary cable (pictured below the secondary) was as some people believe, damaged before the water at high pressure damaged it further, but regardless if it was damaged or not it should’nt have been hit with how every many psi did hit, which was probably more than the suggested 1500 psi when working around buried power cables.
It was in a common ditch, which in this day and age is a common practice in newer subdivisions and developments, where primary power and secondary cables as well telecommunication utilities are buried together in a ditch. Gas-line’s are usually buried a meter away from everything else.
The person(s) that were hydrovacing at the time got away their lives and with only minor injuries to one of the parties. It could have been much worse, causing death to both of them.

This cable could have been damaged before the high pressure water hit it but who’s to say, but in all likelihood it was’nt.
It is recommenced that when working around primary and secondary electric cables that your pressure is at 1500 PSI and your water temperature is at 70 degrees. Any higher pressure and hotter temperatures will rip open the outer coating of both in a matter of seconds.
More on hydrovacing buried power cables in future posts.
