The requested unit will replace an existing unit that was purchased used from the
telephone company in 1562 and later mounted on a 1968 cab and chassis. From that time
through 1978, this unit was the primary maintenance tool of the City's sewer
maintenance program.
In 1978, the City acquired its first hydro -jet cleaner unit which was billed as the
ultimate sewer cleaner for all types of stoppages. After a few years of operating the
hydro -jet cleaner, it was quickly apparent that some tasks could not be correctly
addressed with this unit (i.e., massive root intrusion and extreme grease problems.)
The rodding machine was quickly put back into use for those occasions the hydro -jet
could not handle. The rodding machine abated those stubborn problems efficiently.
Our rodding machine was recently inspected by the original manufacturer. He found
replacements for most components of this unit are not available; they would have to be
machined or fabricated, and he wasn't certain that was even possible.
It is proposed that the City purchase a new hydraulically -operated rodding machine to
be mounted on the existing 1968 cab and chassis. With a 15 -year life expectancy, this
equates to $1,700 per year. Current need for this unit is six to ten times per year.
This amounts to $170 to $280 per each task assigned. These amounts aVe relatively
small compared to health and safety responsibilities of the division and the reduced
liability to the City.
Below is a detailed breakdown of costs:
16 h.p. standard model rodding machine $17,500
Automatic rodding operation 3,500
Remove old unit and install new unit 3,500
Paint existing cab 1,000
Sales tax 1,260
Trade-in or sale - 1,000
Total $25,760
