To inspect a pipe, the camera must either be pushed in front
of cleaning equipment or it must That problem has been solved with the addition of a new, large-diameter,
four-wheel-drive, remote-controlled tractor. This tractor has
a scissor mechanism that raises the camera up to the top of the
pipe above the flow line. In addition, the District has upgraded
the software that analyzes the information gathered by the camera.
The video can now be digitized so The new tractor and software program join the District's other
top-of-the-line preventativeequipment that includes a rodder (a
giant roto-rooter that clears pipes of roots and other debris)
and three hydrojetters (giant water jets that clean the lines).
A crew of six operates all of this equipment. The tools, however,
would be useless without the crew's expertise and dedication. |
In
1993, the District purchased its first "Omni- Eye" camera
to remotely video inspect the almost 300 miles of District sewer
line. It takes about two and a half years to inspect all of the
District's lines. The information collected has allowed Oro Loma
to design cost-effective rehabilitation and replacement programs,
including the recently completed Lewelling and Bayfair sewer line
projects. 
maneuver on its own through the line. Until recently, it has been
difficult to inspect larger pipes up to 66" in diameter,
since the camera could only operate on the bottom of the pipe.
that
individual images and short clips can be incorporated into an
inspection report. The report includes not only printed stills
of the pipe, but also descriptions of the line's condition and
detailed locations of each inspection site. The information is
added to a database so that after an inspection is complete, the
District will have a complete picture of the system's condition
and will be able to access the data by, among other things, date,
address, map coordinates, and operation performed.
