Re: Just when crabbing was peaking
 

Isn't there something in construction similar to stud or electric finders in home building where regardless of what depth a pipe in this case is supposed to be at they can scan an area with some type of thermal or electronic imagery to know exactly what depth critical underground structures are actually at versus where they're supposed to be? I would think with today's technology, something along those lines would not only be available but required before digging blindly.

They mark out the lines , but don’t state the depth .
They mark thousands of runs a month , so for the most part it’s just the lane their service is in .

A lot of times a one-call markout will be performed based off drawings, not actually locating the line. Sometimes the drawings are several feet off. Even ground-penetrating radar isn't 100 percent, as the range can be limited based on soil type, and non-metal lines don't show up as well. Not to be an apologist, but you can be as careful and thorough as possible and still hit something.

I've overseen hundreds of excavating and drilling jobs, and no matter how many paint marks are on the ground I still get a little nervous when we break ground. You never know what you'll find until you start digging.

The heyday of flounder fishing in Quincy Bay was in the 70’s and each man would come home with 50 lbs of filets. And to the South side was a huge outlet pipe that dumped the raw sewage of Boston into the bay. When they started treating the water, the fishery died —— just saying.

And no mention of all the CSO's we have. Combined Sewer Outflow, like the huge one in Perth Amboy.
