Public Content
Information
In the current budget, staff requested funds for continuing combined sewer system repairs. These combined sewer
repairs were identified during the Combined Sewer System Evaluation Study (CSSES) completed in 2015. A copy of this
report is attached.
Much of this work entails rehabilitating existing sewer main segments by inserting a cured -in-place (CIPP) liner inside a
host pipe segment. This method is more cost effective than open -cut excavation and far less disruptive. The Village has
successfully utilized this process since the late 1970s. A short video demonstrating this process can be found at this link.
The scope of work in this year's project includes 31 pipe segments totaling 8,140 lineal feet of combined sewer rated as
category 5. This pipe ranges in size from 8" to 36" in diameter. Category 5 sewers are in "sever structural condition"; the
CSSES study recommends that repairs be completed within one 1 to two 2 years.
In total, there are 25,115 lineal feet of combined sewers rated as category 5. Lining work performed last year
(2016), along with work proposed this year, will correct approximately 40% (10,046 lineal feet) of the category 5
combined sewer defects identified in the CSSES report.
The 2017 project also includes an additional 1,707 lineal feet of lining repairs in the separate sanitary sewer system.
These pipes have all been rated as category 5 defects following condition assessment by Public Works staff following
closed-circuit television camera inspection. These pipes are primarily all 8" in diameter.
In total, the 2017 project will rehabilitate 9,847 lineal feet of combined and separate sanitary sewers.
The CIPP contract being considered this year is a joint bid through the Municipal Partnering Initiative (MPI). MPI is a
collective of Cook County, Lake County and Du Page County municipalities that have leveraged bulk purchasing and
workload sharing to reduce the cost of many municipal services including sewer lining.
Participation in the MPI joint bid award satisfies the village's public bidding requirements. The village attorney advises
competitive bidding is not required when the village, pursuant to its home rule powers, enters into a joint purchasing

7. WAIVER OF WORKERS COMPENSATION/OCCUPATIONAL DISEASE EXPENSE REIMBURSEMENT
The Contractor agrees to waive any and all rights to reimbursement of workers' compensation expenses under
Section 1(a)(4) of the Illinois Workers' Compensation Act (820 ILCS 305), and as amended; and the Contractor
agrees to waive any and all rights to reimbursement of occupational disease expenses under Section 1(a)(3) of the
Illinois Occupational Diseases Act (820 ILCS 310), and as amended.
8. UNBALANCED BIDS
Any bid which is materially unbalanced as to prices for the Base Bid and/or Optional Bid Items may be rejected. An
unbalanced bid is one which is based on the prices significantly less than the cost for some work and/or prices
which are significantly overstated for other work.
The Village of Buffalo Grove and the Municipalities will review all unit prices submitted by the apparent lowest
responsible bidder and will decide whether any of the unit prices are excessively above or below a reasonable cost
analysis value determined by the Owners.
In the event any unit prices are determined to be unbalanced and contrary to the interest of the Village of Buffalo
Grove, the right is reserved to reject such bid at the discretion of the Village of Buffalo Grove.
9. DISCREPANCIES
In all cases of discrepancies between the drawings and specifications, respective Village/City shall be notified in the
manner as identified in the General Terms and Conditions. The specifications shall govern over the drawings. If
work proceeds without obtaining proper interpretations of the conflicting drawings and specifications from the owner
or their designee, the installed work that is not in accordance with the design and best practices must be replaced at
no additional cost.
10. OMISSIONS/HIDDEN CONDITIONS
The drawings and specifications are intended to include all work and materials necessary for completion of the
work. Any incidental item of material, labor, or detail required for the proper execution and completion of the work
and omitted from either the drawings or specifications or both, but obviously required by governing codes, federal or
state laws, local regulations, trade practices, operational functions, and good workmanship, shall be provided as a
part of the contract work at no additional cost to the owner, even though not specifically detailed or mentioned.
11. FIELD MODIFICATIONS
A field modification is written by the owner or his designee to the contractor for purposes of clarification of the
specifications or plans. A field modification is limited to items that do not change the scope of the project.
Field modifications do not affect either the project cost or completion date.
Field modifications become part of the Contract Documents and become binding upon the contractor if he fails to
object within three (3) working days after receiving the modification. A field modification may be used as the basis
of a project cost change or contract extension if all parties agree on the field modification form to a potential future
claim of either party, or that the field modification will be compiled with, but under protest.
Any bid which is materially unbalanced as to prices for the Base Bid and/or Optional Bid Items may be rejected. An
unbalanced bid is one which is based on the prices significantly less than the cost for some work and/or prices
which are significantly overstated for other work.
The Municipalities will review all unit prices submitted by the apparently lowest responsible bidder and will decide
whether any of the unit prices are excessively above or below a reasonable cost analysis value determined by the
Owners.
In the event any unit prices are determined to be unbalanced and contrary to the interest of the Municipalities, the
right is reserved to reject such bid at the discretion of the Municipalities.
16. ADDITIONAL INFORMATION
Should the bidder require additional information about this bid, submit questions via email to: bgfinanoovbg.org.
All such e-mails must contain "2017 Annual Sewer Lining" in the subject line of the e-mail. Questions are required
no later than 112:00 R.M. on March '7, 20117„
ANY and ALL changes to these specifications are valid only if they are included by written Addendum from the
Village of Buffalo Grove to All Bidders. No interpretation of the meaning of the plans, specifications or other
contract documents will be made orally. Failure of any bidder to receive any such addendum or interpretation shall
not relieve the bidder from obligation under this bid as submitted. All addenda so issued shall become part of the
bid documents. Failure to request an interpretation constitutes a waiver to later claim that ambiguities or
misunderstandings caused a bidder to improperly submit a bid.
The Village of Buffalo Grove recognizes that in some cases the information conveyed in this RFB may
provide an insufficient basis for performing a complete analysis of the RFB requirements. Prospective
bidders are, therefore, requested to make the best possible use of the information provided, without the
expectation that the Village of Buffalo Grove will be able to answer every request for further information or
that the schedule for receipt and evaluation of proposals will be modified to accommodate such request.
17. CONTACT WITH VILLAGE/CITY PERSONNEL
All bidders are prohibited from making any contact with the municipalities' Presidents, Trustees, or any other official
or employee of the municipalities (collectively, "Municipal Personnel") with regard to the Project, other than in the
manner and to the person(s) designated herein. The Purchasing Department or Approved Equal reserves the right
to disqualify any bidder found to have contacted Municipal Personnel in any manner with regard to the
Project. Additionally, if the Purchasing Department or Approved Equal determines that the contact with Municipal
Personnel was in violation of any provision of 720 ILCS 5/33E, the matter will be turned over to the Cook County
State's Attorney for review and prosecution.
18. DISCLOSURE OF POTENTIAL OR ACTUAL CONFLICT OF INTEREST
Each Municipality's Code of Ethics prohibits public officials or employees from performing or participating in an
official act or action with regard to a transaction in which he has or knows he will thereafter acquire an interest for
profit, without full public disclosure of such interest. This disclosure requirement extends to the spouse, children

the conflict of interest in its bid, identifying the name of the municipal official or employee with whom the conflict
may exist, the nature of the conflict of interest, and any other relevant information. The existence of a potential or
actual conflict of interest does NOT, on its own, disqualify the disclosing Bidder from consideration. Information
provided by Bidders in this regard will allow The Village of Buffalo Grove to take appropriate measures to ensure
the fairness of the bidding process.
The Village of Buffalo Grove requires all bidders to submit a certification, enclosed with this bid packet, that the
bidder has conducted the appropriate investigation and disclosed all potential or actual conflicts of interest.

Wherever the word "Owner" appears in this document, it shall be interpreted to mean each municipality
representative.
Wherever the word "Contractor" appears in this document, it shall be interpreted to mean the firm,
partnership, joint venture, or corporation contracting with each municipality for performance of prescribed
work.
Scope of Project
This project includes quantities for 41,865 linear feet of sanitary and storm sewer lining in various sizes of
cured -in-place pipe lining (CIDP), rehabilitation and restoration of structural integrity of the existing sanitary
pipes by the Inversion and Curing of a Resin -Impregnated Tube process and all related and ancillary work.
The work contained on this project is located within easements or right-of-ways of the Village of Arlington
Heights, Village of Buffalo Grove, City of Rolling Meadows, Village of Mount Prospect, and the Village of
Lincolnshire.
Each municipality has the right to delete from or add to the contract quantities at the contract unit costs for
construction.
While the Village of Buffalo Grove shall serve as the central point of contact to facilitate the bidding process
described in this Contract, each municipality further reserves the right to reject any and all bids or parts
thereof, to waive any irregularities or informalities in bidding procedures and to award the contract in a
manner best serving the interest of the municipality. Work included is shown on drawings prepared by The
Village of Buffalo Grove which has been supplied by each municipality. The lining work shown on the
drawings is not conclusive and is subject to change. The drawings can be found in "Appendix B".

Materials
A. Tube - The sewn Tube shall consist of one or more layers of absorbent non -woven felt fabric and meet the
requirements of ASTM F1216, Section 5.1. The tube shall be constructed to withstand installation
pressures, have sufficient strength to bridge missing pipe, and stretch to fit irregular pipe sections.
Additional requirements for the Tube include:
1. The wet out Tube shall have a relatively uniform thickness that when compressed at installation
pressures will equal or exceed the calculated minimum design thickness.
2. The Tube shall be manufactured to a size that when installed will tightly fit the internal circumference
and length of the original pipe. Allowance should be made for circumferential stretching during
inversion. Overlapped layers of felt in longitudinal seams that cause lumps in the final product shall
not be utilized.
3. The outside layer of the Tube shall be coated with an impermeable, flexible membrane that will
contain the resin and all the resin impregnation (wet out) procedure to be monitored.
4. The Tube shall be homogeneous across the entire wall thickness containing no intermediate or
encapsulated elastomeric layers. No material shall be included in the Tube that may cause
delamination in the cured CIPP. No dry or unsaturated layers shall be evident.
5. The wall color of the interior pipe surface of CIPP after installation shall be a relatively light reflective
color so that a clear detailed examination with closed circuit television inspection equipment may be
made.
6. Seams in the Tube shall be stronger than the non -seamed felt material.
7. The Tube shall be marked for distance at regular intervals along its entire length, not to exceed 5 ft.
Such markings shall include the Manufacturer's name or identifying symbol. The tubes must be
manufactured in the USA.
B. Resin - The resin system shall be a corrosion resistant polyester, vinyl ester, or epoxy system including all
required catalysts, initiators or hardeners that when cured within the tube create a composite that satisfies
the requirements of ASTM F1216, the physical properties herein, and those which are to be utilized in the
design of the CIPP for this project. The resin shall produce a CIPP that will comply with the structural
and chemical resistance requirements of this specification.
Structural Requirements
uirements
A. The CIPP shall be designed as per ASTM F1216. The CIPP design shall assume no bonding to the original
pipe wall. The liner should be designed using 5% ovality and groundwater level at the surface.
B. The Contractor must have performed long-term testing for flexural creep of the CIPP pipe material
installed by his Company. Such testing results are to be used to determine the long-term, time dependent
flexural modulus to be utilized in the product design. This is a performance test of the materials (Tube and
Resin) and general workmanship of the installation and curing. A percentage of the instantaneous flexural
modulus value (as measured by ASTM D790 testing) will be used in design calculations for external
buckling. The percentage, or the long-term creep retention value utilized, will be verified by this testing.
Retention values exceeding 50% of the short-term test results shall not be applied unless substantiated by
qualified third party test data to the Owner's satisfaction. The materials utilized for the contracted project
shall be of a quality equal to or better than the materials used in the long-term test with respect to the
initial flexural modulus used in the CIPP design.
C. The Enhancement Factor `K' to be used in `Partially Deteriorated' Design conditions shall be assigned a
value of 7. Application of Enhancement (K) Factors in excess of 7 shall be substantiated through
independent test data to the satisfaction of the Owner.

was performed by consulting engineer, Baxter & Woodman of Crystal Lake, Illinois. It identified
almost $15 million worth of combined sewer repair work including manhole rehabilitation, pipe
replacements and pipe lining. 260,000 feet of combined sewer pipe was assessed during this
project. Repair work was further prioritized and categorized as follows:
• Approximately 8% of the pipes were in severe structural condition (Grade 5). The report
recommended that repairs be completed within one (1) to two (2) years. The estimated
cost to repair sewers in this classification was $2,481,600.
• 10% were in poor structural condition (Grade 4). Completed repairs were recommended
within the next three (3) to four (4) years. The estimated repair cost for sewers in this
classification was $2,548,000.
• 20% had moderate structural defects (Grade 3) requiring rehabilitation within the next
five (5) to ten (10) years. The estimated repair cost for sewers in this classification was
$5,240,000.
• 34% had minor structural defects (Grade 2) that did not require repairs. However, the
report recommended these pipes should be periodically re-examined to assure that
noted defects do not worsen. The estimated cost to repair these defects was
$4,158,000.
• 24% were in very good condition (Grade 1). No discernable defects were observed. No
repairs were recommended.
To date, the bulk of the major defects (all of Grades 5 and 4, with a portion of Grade 3) have
been corrected. The remaining pipe was identified in 2004 as being of low to moderate risk
(Grades 1 to 3).

Additionally, 11 % were Grade 2 and 35% were Grade 1 or Grade 0. Grade 2 sewers do not
require work at this time but continued monitoring is recommended. Grade 1 and 0 pipes are in
good or very good condition and do not require any repairs.
None of the previously lined sewers inspected (18,000 feet) displayed any defects and all were
in good condition.
The continued degradation of sewers is anticipated. Generally, sewers pipes have a 50 -year
design life. Most of the Village's combined sewer system was installed between the 1920s and
1950s. As such, all of the these pipes are over 50 years old and some are approaching 90
years of service.
RECOMMENDATION
Staff recommends continued accelerated rehabilitation of sewer pipes in the combined sewer
area at a pace of $800,000 - $1,000,000 per year.
However, a key component to funding this level of sewer rehabilitation is the Sewer
Infrastructure Fee ($5/month per sewer service line). As noted previously, this fee generates
approximately $800,000 in revenue and is slated to sunset in 2016. Continued accelerated
combined sewer rehabilitation without this funding source does not seem feasible given other
capital and operating demands on the existing water/sewer user rate structure.
Staff seeks direction from the Village Board regarding the disposition of the Sewer Infrastructure
Fee.
Please present this matter for the Village Board's consideration at the August 11, 2015
Committee of the Whole meeting. Appropriate staff, along with a representative from Baxter &
Woodman will be available to present the report and facilitate discussion.

1.1 General
The Village of Mount Prospect Illinois is located approximately 22 miles northwest of downtown
Chicago in Cook County. The Village encompasses an area of approximately 10.37 square miles. The
2010 Census reported the Village's population as 54,167.
Like many older Illinois communities, portions of the Village's sanitary sewer system include
combined sewers (sewers designed and constructed to collect and convey both sanitary sewage and
stormwater runoff). The combined sewer system was constructed between the 1920s and 1950s
and consists of approximately 260,000 feetofcombined sewers ranging in size from 8 -inch diameter
sewers that serve residential streets to 72 -inch diameter interceptors that convey flow to the
Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) interceptor sewers. The
system is located in the central portion of the Village bound approximately by Kensington Road to
the north, Mount Prospect Road to the east, Golf Road to the south and Busse Road to the west New
construction of this type of sewer is no longer permitted and separate sanitary and storm sewers
are currently required. The pipe material consists primarily of vitrified clay pipe (VCP) and
reinforced concrete pipe (RCP). There is also a small quantity of ductile iron and polyvinyl chloride
(PVC) truss pipe.

"5" on section "8S" of the Village's utility atlas. Inlets and catch basins are numbered sequentially
(starting at one) and are referenced to the manhole (MH) to which they are tributary. For example,
"8S-CS5-IN 1812" is the name for combined sewer inlet "1812" (which is tributary to "MH 8S-CS5").
Where available, manhole IDs from Mount Prospect's existing combined sewer atlas were used.
Where no existing manhole ID was available, one was assigned by the survey crew.
2.2.2 Asset Attribute Information
Asset attribute information was collected for each structure surveyed, Attributes recorded include
structure type, materials of construction, inlet and outlet pipe information (locations, material and
diameter), direction of flow, and rim to invert depth information. Asset attribute information was
collected for inventory purposes and was added to the GIS database.
2.2.3 Closed Circuit Television (CCTV) Inspection
CCTV inspection is utilized to assess the condition of the sewer lines. A specially designed camera
is inserted into the sewer and used to visually inspect the interior of the sewer. The camera is either
pulled through by a winch at the downstream manhole, or it is mounted to a self-propelled, remote
controlled "crawler".
In order to effectively determine the structural condition of the pipe with CCTV inspection, the
majority or the interior of the pipe needs to be visible during inspection. Where required, debris
and roots are removed prior to televising using a high powered water jet (jetting). Also, in sewers
where the water level is high enough to submerge the camera, the water level is lowered by using
the jetter ahead of the camera (effectively "pushing" the water out of the way).
The CCTV camera is equipped with lights and is capable of rotating 360 degrees to observe the entire
interior of the sewer. As the camera is guided through the pipe, the operator notes the location of
any structural defects that are observed as well as the locations of service laterals, root intrusions,
pipe size or material changes, and buried manholes. These items are cataloged for later use when
assessing the structural condition of the sewer. The CCTV inspection is recorded in both VHS and
DVD formats. Written inspection logs documenting the inspection and operator observations
accompany the CCTV inspection videos.
An office review was conducted for each CCTV inspection and inspection log. The location (in terms
of number of feet from the upstream manhole) and severity of each structural defect was identified
and a defect code was assigned. The televising revealed a wide range of construction materials. The
majority (96%) of the combined sewers is constructed of either VCP or RCP. The remainder of the
sewers (4%) is constructed of either ductile iron or PVC pipe. All of these are common construction
materials for both sanitary and combined sewers, although some materials (such as VCP) have been
used less frequently in recent years. Each material has advantages and disadvantages to its use. One
of the main disadvantages of VCP pipe is that it is very brittle. Incorrect installation and trench
settlement often result in cracked or shattered pipe. One of the main disadvantages of RCP pipe is
that it is susceptible to hydrogen sulfide deterioration, which reduces the wall thickness (and,
therefore, strength) of the pipe.

recommended for repair within five to ten years. Grade 2 sewers had minor defects that did not
require rehabilitation at that time, but were recommended to be re -inspected from time to time to
verify that the defects had not worsened.
2.2.6 Rehabilitation Methods
There are several techniques for sewer rehabilitation. Each sewer segment must be reviewed
individually to determine which rehabilitation technique(s) is most appropriate given the structural
and maintenance condition of the pipe. In short, "one size does not fit all". The following
rehabilitation techniques were considered for this project
Cured -In -Place Pipe (CIPP)
CIPP involves inserting a resin -impregnated flexible liner into an existing deteriorated sewer from
one manhole to another. The liner is then expanded to the shape of the sewer using water or air.
The medium used to expand the liner is heated to a designated curing temperature which hardens
the resin to form a rigid structural repair. After curing, service laterals are reinstated from the inside
of the sewer with remotely controlled cutters. The finished product is at least as strong as the
original pipe and is expected to have a minimum 50 -year design life. The rigid liner does not contain
any joints within the repair, which eliminates the possibility of future leaks due to joint separation
or root intrusion. Other advantages of this repair method are that it is usually significantly less
expensive than open cut replacement, causes minimal disruption; and can be completed in a short
amount of time.
CIPP installation is conducted in situ and generally requires no excavation. CIPP can typically be
installed through minor to moderately deformed pipe without additional work, although severely
deformed pipe must first be excavated and replaced prior to CIPP installation.
Because CIPP is inserted into an existing sewer, the inside diameter of the host sewer will be
decreased by the thickness of the liner. However, this decrease in flow capacity is minimal and is
offset by the improved structural condition of the pipe. Also, lining with CIPP can increase a pipe's
smoothness and reduce root intrusion, resulting in improved flow characteristics and increased
capacity.
Sewer Replacement
Where a CIPP repair is not possible due to a partially or fully collapsed pipe, excavation and
replacement (E&R) is necessary. This method is generally the most expensive and most disruptive
technique. In most cases, an E&R repair is only necessary on a portion of sewer segment After the
repair is complete, a full manhole -to -manhole liner is typically installed to complete the
rehabilitation of the sewer section. All sewers requiring an E&R repair are grouped into Grade S.
2.2.7 Previous Recommendations
Of the approximately 260,000 feet of combined sewers inspected in the previous study, 8% were in
severe structural condition (Grade 5) requiring rehabilitation within 1 to 2 years, 11% were in very

It should be noted that approximately 20% of the total rehabiliation dollars spent was for the critical
Grade 5 E&R repairs. The significance of this value will be discussed later in this report.

rehabilitating a sewer segment with a single severe defect (Grade 5) rather than a sewer segment
with numerous minor defects (Grade 3).
3.3 Recommended Repairs
Appendix 2 contains the prioritization table for the recommended rehabilitation work first sorted
from Grade 5 to Grade 1, then by the overall structural rating. Appendix 3 is sorted by the upstream
manhole ID number to assist in finding a specific pipe segment. As with the previous study,
rehabilitation for Grade 5 sewers are recommended for repair within one to two years. Grade 4
sewers are recommended for repair within three to four years. Grade 3 sewers were recommended
for repair within five to ten years. Table 6 shows the total project costs broken down by overall
condition grade.

It should be noted that of the estimated total rehabilitation costs for the Grades 3, 4 and 5 repairs,
only $35,000 (0.3%) of it is for critical repairs requiring excavation and replacement This is
compared to approximately $1.52 million (20%) spent on E&R repairs from the 2002 evaluation.
Review of the 18,000 feet of lined sewers showed that all of the previous CIPP repairs televised
remain intact and in good condition. This is to be expected since CIPP repairs are designed for a
minimum 50 -year service life.

5. COMPARISON BETWEEN 2002 AND 2015 EVALUATIONS
This section of the report discusses the Findings of the 2002 and 2015 evaluations to better
understand the rate at which the combined sewers are deteriorating. Figure 1 illustrates the
percentage of sewers from the 2002 evaluation grouped by defect grade.
FIGURE 1
As the figure shows, approximately 40% of the sewers inspected fell into the Grades 3, 4 and 5
categories. These sewers ranged in age from approximately 50 to 80 years old. Recall that all of the
Grade 4 and 5 repairs were completed as well as approximately 31% of the Grade 3 sewers.
