The Waste Water Collection Department has a
variety of equipment used to locate, maintain, and repair problems within the sanitary
sewer system.
Pictured is an employee inside the department's camera truck viewing a monitor
while operating a "track camera" as it is being "driven" through a
sewer pipe along S. Wayne Street. The track camera is about a 40 lb. device with
roughly two-dozen lights surrounding the camera. The track camera moves on treads similar
that of a bulldozer. This camera is connected by a braided steel cable, which is
normally operated for distances of 100 to 400 feet, but has up to 1000 feet of cable.
The track camera can enter a pipe as small as six inches. The camera
truck also has "push camera" which has up to 200 feet of cable. The push
camera can be used in pipe as small at 1 1/2 inches.
This department has a dump truck that is used during sewer digs, and is some times
used to plow snow in the winter.
A backhoe, which is used during sewer digs, is also essential part of departmental
equipment.
The trailer jet, as shown on the personnel page, is used to clean out the smaller
sewer links.
The Jet Vac Combo truck, as shown on the upper level page, is used on
larger sewer lines. Both jet units have a spray nozzle on a hose, which can spray
1500-2000 psi of pressured water back the same direction as the hose. This action
thrusts the nozzle forward down the pipe. The size of the nozzle placed on the hose
is determined by the size of the pipe. The hose is then retracted as the
high-pressure water is spraying. This action cuts through roots, and washes them
away. The Jet Vac Combo truck also has a vacuum, which sucks up the debris.
On rare occasion, this department is confronted with a root growth so dense, that jet
units are not capable of cleaning the growth out. An older "stiff router"
unit is then used.
