Securing the Sensor Cable in the Pipe
and Manhole
Securing the sensor cable from the ring (or band, when applicable),
along the pipe crown, and up the manhole helps prevent debris from
collecting on a sagging cable or between the cable and the pipe
crown.
Do not allow the sensor cable to hang down in the pipe or sag in the
manhole. Loose cables could present a safety hazard in the
manhole or increase the potential for sensor or monitor damage.
The cable should be secured along the pipe crown and manhole wall
under all circumstances.
Note: Do not secure a wireless communication antenna
cable with the sensor cable! Refer to Setting Up Wireless
Communication in Chapter 4, Communication, for
information on securing the antenna cable in the manhole.
Secure the cable from the ring (or band) to the monitor location in
the manhole in the following way:
1. Wrap the cable with an 8-inch by 0.14-inch cable tie attached
to a plastic anchor installed at the top of the pipe.
Note: If a plastic anchor will not serve as an adequate
anchor for securing the cable based on the structure of the
pipe, install a ¼-inch x 2 ¼-inch bolt instead.
 Drill a 3/8-inch hole in the pipe crown.
 Drive the plastic anchor into the pipe with a hammer until
flush and secure.
 Run the cable tie through the loop in the plastic anchor and
around the cable.
 Tighten the cable tie around the cable, and cut off the
excess cable tie material.
