There has been a very interesting process going on in our alleys lately. The Michels Corporation has been refurbishing our sewer lines with out digging them up.
They can inspect, clean, repair, re-line and improve our old sewer lines, many still existing from the days of clay tile!
I was fascinated by the process of inspecting the pipes. Here one of the operators is watching the monitor as he controls a machine pulling a camera through a section of pipe.
Here is a close up of the monitor showing the camera's view.
This is the camera. Actually a spare camera. Once the pipe has been inspected and cleaned a liner is "blown through", inflated and sealed in place with resin. Then the camera is pulled through to guide a cutting machine that opens the laterals from businesses and residences back into the newly completed pipe.
Very interesting. Here's their description of the process.
I believe they have finished this phase of sewer rework and have headed back to Salem, Oregon.
