FTLComm - Tisdale - August 17

Its portable toilets for a three block section of Tisdale as crews work around the clock repairing the sewer lines. The lines in this part of the community are concrete and some are clay, over the years the ground shifts slightly enough to dislodge the joints and obstructions develop. This Edmonton based crew can pretty well construct a new line using their high tech equipment and modern techniques. The truck above and the one lower left are connected with a line run through the
damaged line. A rotating cutting head clears obstructions and moves itself through the line with water pressure. All of the work is directed and controlled by an operator sitting before a console watching the progress on the video camera that runs along with the equipment.

Damaged and broken areas in the line can be repaired producing a line that is better then the original using plastics that are pumped in, creating a new liner inside the old concrete pipe.

The repair process involves using video lines, high pressure air hoses, water pressured lines, mechanical cutting devices, liquid plastic and ice used to slow the setting of the plastic.

When discussing the process with some of the workers I suggested that the odds must be about 50/50 that digging will be needed, this brought a response of laughter, "We never need to dig!"
