INTRODUCTION
The purpose of this memo is to recommend adoption of the attached resolution
approving the plans, specifications, form of contract and the estimated cost for the 2009
Sewer CIPP Lining Project to be considered at a public hearing.
DISCUSSION
With age, sanitary sewers deteriorate. Cracks and bad joints form, compromising the
integrity of the sewer. In addition, stormwater and groundwater can infiltrate into the
sanitary sewer. Both conditions can cause the overloading of the City's sanitary 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 "trenchless" technologies. Cured-in-Place Pipe (CIPP) is a versatile
trenchless method for restoring structural integrity to sewer mains.
CIPP is aresin-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 the flow
capacity of the pipe. The seamless pipe also prevents infiltration. Robotic cutters are
then used to restore private sewer service connections.
The sewers identified for lining as part of the 2009 Sewer CIPP Lining Project are as
follows:
Location Sewer
Diameter
Inches Length
(Feet)
Glen Oak from Vernon St. to Edina St. 8-inch 333
Grove Terrace near 12th St. 8-inch 176
Kirkwood St. from Alta Vista to W. Locust 8-inch 1,676
Fenelon St. (Storm Sewer) 12-inch 50
W. 32"d St. from Wildwood to the east 24-inch 825
TOTAL 3,060
In addition, two brick manholes on Loras Boulevard near Prairie Street will be
rehabilitated. In addition to the sanitary sewers to be lined, a small section of storm
sewer on Fenelon Street will also be lined as part of the project.

I recommend approval of the plans, specifications, form of contract and the estimated
cost for the 2009 Sewer CIPP Lining Project.
