City Engineer Gus Psihoyos is recommending acceptance of the 2004 Sanitary Sewer

amount of $74,801.89, which is a 8.73% decrease from the original award amount of
$81,329.16, mainly because of the removal of the 400 block of Kaufmann Avenue from

TO:
SUBJECT: 2004 Sanitary Sewer Lining Project
(CIP 31 OA62-71 01637: Sanitary Sewer Lining Program)
INTRODUCTION
The enclosed resolutions provide for the acceptance of the 2004 Sanitary Sewer Lining
Project.
BACKGROUND
With age, clay sanitary sewers deteriorate. Cracks and bad joints form, compromising
the integrity of the sewer. In addition, stormwater and groundwater can infiltrate into the
sewer. Both conditions can cause the overloading of the sewer system.
The high costs and inconvenience to the public associated with the excavation and
restoration of pavement for sanitary sewer rehabilitation projects has led to the
development of "trench less" technologies. Cured-in-Place Pipe (CIPP) is a versatile
trenchless method for restoring structural integrity to sewer mains.
CIPP is a resin-impregnated tube that is installed in an existing damaged or leaking
sewer. Once inserted into the pipe, it is expanded and cured by applying heat. The liner
is a seamless, joint-less, pipe with a smooth inner surface that increases flow capacity.
The seamless pipe also prevents infiltration. Robotic cutters are then used to restore
active lateral connections to the line.
In January of 2005, the project was awarded to the low bidder, Visu-Sewer Clean &
Seal Co. of Pewaukee, Wisconsin in the amount of $81,329.16.
DISCUSSION
Visu-Sewer has completed the project having lined the following sewers:
John F. Kennedy Road and Pennsylvania Avenue
Algona Street between Bennett Street and 3rd Street
Mayfair Court
Rhomberg Avenue west of Sumner Street
Kaufmann Avenue near North Grandview Avenue
Kaufmann Avenue (section in the 300 block)
Kaufmann Avenue (section in the 500 block)
Kaufmann Avenue (section in the 1300 block)
A section of sewer in the 400 block of Kaufmann Avenue was removed from the project
because an excessive lateral flow prevented a proper installation. The excessive flow
has been rectified and the section will be lined as part of the 2005 sanitary sewer lining
program.
The project was completed at the final contract amount of $74,801.89, which is an
8.73% decrease from the original award amount.
RECOMMENDATION
I recommend that the City Council accept the improvements and establish the final
contract at $74,801.89.
BUDGET IMPACT
The project cost summary for the 2004 Sanitary Sewer Lining Project is as follows:
