2003 SEWER REHABILITATION CURED-IN-PLACE PIPE (CIPP)~
BID RECOMMENDATION IN THE AMOUNT OF $319,244
Background
The current 2003 budget contains funding for sanitary sewer rehabilitation utilizing the
cured-in-place pipe method. This year, staff has identified several sewer segments that
are eligible for repair utilizing this method. The cured-in-place pipe technique has been
utilized extensively throughout the Village sewer system since the early 1980s. It
involves inserting a felt tube, saturated with resin, into a sewer pipe and allowing it to
cure for a period of six (6) hours. The curing process is conducted under pressurized
conditions utilizing super-heated water. The process requires no excavation, minimizes
service interruptions, and results ina virtually seamless, structurally sound, pipe within a
pipe.
Over the years, CIPP rehabilitation has become an integral part of our sewer system
maintenance program. Areas that have been rehabilitated decades ago using this
process are still exhibiting peak hydraulic performance and strength. The areas selected
for CIPP rehabilitation are based on considerations such as the area served by the
sewer segment, overall pipe segment conditions, and the frequency of seWer surcharge
incidents.
Bid Results
At 10:00 AM on Tuesday, September 16, 2003, sealed bids were received from three (3)
of four (4) CIPP rehabilitation contractors who were invited to bid. All bids were publicly
opened and read aloud at that time and a public notice was placed in a local newspaper

Discussion
This year's rehabilitation program consists of 7,536 lineal feet of 8, 10, 12, 15, and 24
inch vitrified clay pipe (VCP) and concrete sewer pipe in five (5) separate areas. These
areas are situated throughout the Village. The table below, and the attached map,
denote the proposed project areas:

4 S. Elmhurst Road (900 block) 890 LF 8" dia. VCP
5 Cherrywood Drive (1100 block) 806 LF 8" dia. VCP
7,536 LF
Closed circuit television inspection has revealed that these areas have significant
structural defects and potential flow restrictions. Additionally, staff feeis it is an
opportune time to effect repairs to the sewers along south Emerson Street near the new
Village Hall and Parking Deck project prior culmination of construction activities and
reconstruction of the roadway surfaces. The' use of CIPP rehabilitation will greatly
prolong the life of these sewers and significantly reduce the potential for pipe failure.
Recommendation
I recommend accepting the lowest qualified bid of $319,244 as submitted by Insituform
Technologies of Lemont, Illinois. Sufficient funding for this proposed project exists in the
2003 budget.
