Sewer Lining Project
Work on this project began late last week
with the contractor installing pipe for
sewage bypass pumping on a segment of
the 27 -inch sewer trunk line that runs from
north Lake Marion to Ipava Avenue. The
project will install a cured in -place pipe
lining to combat the effect of hydrogen
sulfide gas which is causing the concrete
pipe to deteriorate. Hydrogen sulfide gas
results from the breakdown of organic
matter in the absence of oxygen. The gas is
soluble in water and forms hydrosulfuric
acid which eats away at the concrete sewer
piping. Bypass pumping will isolate the
affected segment of pipe so that it can be
cleaned and the lining installed with
minimum delay. The impact
of this project to those living
along the trunk line is
significant. Homes that are
tied directly into the trunk line
will not be able to use water or
sewer for between 24 and 48
hours while the liner is
installed and cures. Others
living along lines that feed
into the trunk line will not lose
the use of their water and
sewer, but may see equipment

parked at manholes to remove sewage and keep their services open. The project
may take as long as 60 days to complete and the bypass pumping will be in place
until the project is completed.
+ Cedar Avenue Paving
The Dakota County project to
upgrade Cedar Avenue from
181ST Street north to County
Road 46 is nearing completion
with just a few minor pieces left
to finish. Significantly, the
paving of the final layer of
asphalt is nearing completion.
The majority of Cedar Avenue
was paved during the latter part
of September with just the
intersection at Dodd
Boulevard remaining at the
end of the month. The focus
of the project was on
widening Cedar Avenue to
accommodate bus only
shoulder lanes and also
included building noise and
retaining walls, upgrading
and relocating public and
private utilities, and
upgrading signal systems
and street scraping.
❖ Fleet Maintenance Activities
In preparation for the winter
season, Fleet Maintenance staff
focuses on preparing dump
trucks and other pieces of
equipment to plow snow. One
important task is completing
Department of Transportation
(DOT) inspections. Among
other conditions, DOT
inspections are required on any
vehicle or combination of
vehicles, i.e. a truck and trailer,
having a gross vehicle weight of greater than
26,000 pounds. This pertains to all of the
City's dump truck fleet, as well as fire engines
and some of the small 1 -ton trucks when
towing a trailer. Several of the City's fleet
service technicians are certified by the
Minnesota Department of Public Safety to
perform these inspections. The detailed
inspections go through the vehicle from
bumper to bumper inspecting the brakes,
exhaust system, fuel system, steering, tires
and wheels, lights, and other key items.
Going well beyond checking the operation
of an item or system, the technicians look for
broken, loose, or missing components and
measure movement and the placement of
components within strict tolerances. Out of
tolerance conditions must be corrected
before the vehicle can be declared road worthy. These DOT inspections are very
serious as they are part of the records reviewed during an accident investigation.
Incomplete or poorly conducted inspections can have an adverse effect on both
the vehicle owner and the inspecting technician. Lakeville's fleet service
technicians take great pride in their work and in complying with the stringent DOT
inspection program.
