Letter Proposal ;
Pear Street Booster Station Water Main Condition Assessment
PREPARED FOR: Brian Heaston, PE,City of Bozeman
PREPARED BY: Court Harris, PE Jacobs
DATE: November 18,2020
This letter proposal is for Jacobs Engineering Group Inc. (Jacobs)to provide professional
services described herein in support of the City of Bozeman's (City) assessment of the Pear
Street Booster Station Water Main.This proposal includes separate phases, including
requested water main break investigation support services, and additional follow-on
services that the City may authorize at its discretion.
Background
The Pear Street Booster Station water main experienced a break on Saturday, November
14, 2020. City staff were able to isolate the damaged section of water main and in the
process examined the pipeline (see Figures 1) and recovered a large section of pipe
material(see Figure 2). In follow-up communications, City staff noted that the water main
is 18-inch cast iron (CI).The pipe material at the break location was installed circa 1957.
Downstream of the booster station,the pipe material transitions to CI pipe that was
installed circa 1925 (see Figure 3).
The Pear Street Booster Station was recently upgraded with new pumping, mechanical,
electrical and controls systems.The system was in operation for approximately 6 months
prior to the November 14th break.
Approach—Phase 1: Water Main Break Investigation Support
The cast iron pipe segment recovered by the City will be analyzed by a certified materials
testing lab. Lab analysis of this representative segment will be used to determine if the
pipe material has been exposed to corrosion or other mechanisms that would result in
reduced pipe structural integrity.Jacobs review of the lab testing results will be used by
the City as a basis of determining or excluding potential causes of the November 141h
break.

Proposal—City of Bozeman
Pear Street Booster Station Water Main Condition Assessment
Approach— Phase 2: Additional Water Main Condition Assessment Services
(Optional Services)
The water main condition assessment process follows a Tiered Approach to deploy
inspection technologies in a progressive,stepwise manner. Early assessment tiers utilize
technology tools that are easily deployed, have the smallest footprint requirements, and
are least cost. Later tiers have increasingly targeted focus areas, more involved
deployment efforts, and higher costs.As pipe assets are characterized through the initial
tiers, high risk assets will be selected for further evaluation in the subsequent tiers. Brief
descriptions of the tiers are as follows:
• Tier 1 is a survey level assessment that identifies areas of suspected poor condition.
For transmission mains,Tier 1 activities can include records review,topside
appurtenance inspection, and pipe/soil corrosion surveys. Results are used to develop
recommendations for continued preventative maintenance and to select assets for
Tier 2 inspections.
■ Tier 2 includes more detailed inspections to confirm defect quantity and severity. For
transmission mains,Tier 2 activities can include direct assessment of the pipe through
excavated test pits. Results are used to refine the recommendations for preventative
maintenance, and identify those pipe segments in need of rehabilitation or
replacement(may transition to design phases after Tier 2) and/or further Tier 3
inspection.
■ Tier 3 involves specialty investigations where more detailed information is required, in
particular to inform the design of repairs.Tier 3 activities can include deploying in-line
inspection tools such as"smart pigs,"dewatering and inspection, and destructive
coupons. Results are used directly for detailed design of repairs or rehabilitation.
This approach balances risk with inspection costs, and is focused on cost-effective
condition assessment. Inherent in such an approach, accounting for any and all potential
failure mechanisms cannot be guaranteed. However,this assessment will identify the
Locations with the largest risk exposure, and appropriate remediation measures.
Scope of Work
Jacobs will provide the following services under the corresponding tasks:

1. Introduction and Purpose of Assessment
A proactive pipeline condition assessment program allows the MWMC to more accurately anticipate costs
for inspection and capital improvements.Optimal ownership costs include a balanced approach to
condition assessment,to maximize useful life of assets prior to renewal via either replacement or
rehabilitation.
This technical memorandum (TM)describes a tiered condition assessment plan of both gravity and
pressure pipe assets,outlining available approaches and a timeframe for when to proceed to subsequent
inspection tiers.
2. Existing Buried Pipe Infrastructure
The following subsections describe the existing buried pipe infrastructures for MWMC and capital planning
considerations based on the existing network and usage.
2.1 Buried Pipe Assets
The cities of Springfield,Oregon,and Eugene,Oregon manage a collections system network that conveys
municipal wastewater to the Eugene-Springfield Water Pollution Control Facility(WPCF).The buried pipe
infrastructure includes both gravity and pressure pipe assets downstream of an individual municipal
collection systems'network,as well as the process and utility piping within the WPCF and between the
WPCF and the BiosoLids Management Facility and BiocycLe Farm.A summary of pipe assets is included in
Table 2-1,with a more comprehensive table of pipe assets shown in Appendix A.This table is maintained
by the WPCF Operations and Maintenance(0&M)team, and is updated periodically. It may not include
every buried asset or attribute,such as pipes less than 4 inches in diameter.The type of active or passive
corrosion protection systems is also included on the table,as applicable.

Information
The MWMC has WPCF record drawings,computerized maintenance management system work order

Interceptor.
3. Evaluation Approach
This condition assessment plan utilizes a tiered approach to deploy inspection technologies in a
progressive,step-wise manner.As pipe assets are characterized through the initial tiers, higher risk assets
are selected for further evaluation in the subsequent tiers.The goal is for the cost of condition assessment
implementation to not exceed the benefits gained(that is, use technologies that provide the appropriate
information for the stage of assessment and that are worth the cost based on the price of replacement
and/or rehabilitation).
2 PPS0924201644CVO
Task 1 Draft Buried Pipeline Condition Assessment Plan
The first step is a Tier 0 desktop analysis,where known information about the pipe network is collected
and evaluated to identify higher risk assets based on age, criticality,location,and work order history,and
assets are prioritized for assessment.A Tier 1 condition assessment is then carried out utilizing
technological tools that:are easily deployed;have the smallest footprint requirements;and are the lowest
cost. Based on Tier 1 results,Tiers 2 and 3 may be deployed sequentially,with each having a more invasive
approach to identify pipes that require rehabilitation, repairs, or other preventive maintenance,and to
obtain information to evaluate potential repair approaches.Tiers 2 and 3 involve technologies that:target
focus areas; have more involved deployment efforts;and have higher corresponding implementation
costs. Figure 3-1 shows the progression of identifying assets for repair through each tier of condition
assessment. Each tier is used as a screening process for subsequent tiers.As a result,each tier is deployed
on a progressively smaller focus area to prevent unnecessary investigations of pipes in good condition.
Tier 0 is performed on all pipelines.Tiers 1, 2,and 3 utilize different inspection technology for gravity and
pressurized pipes.The following subsections describe the various tiers as they apply to the MWMC,and are
organized based on gravity or pressurized assets.

Figure 3-1.Tiered and Adaptive Plan Concept
3.1 Tier 0 for Pressure and Gravity Assets
Tier 0 for both pressure and gravity assets consists of a desktop evaluation of relative risk to select focus
areas for field activities that begin with Tier 1.This task consists of compiling known information regarding
pipe assets within the network to identify assets that may have elevated risk ratings based on pipe age,
diameter,construction material,soil conditions,and other characteristics. Risk ratings include criteria for
Likelihood of failure(LOF)and consequence of failure(COF),summarized as follows:
LOF criteria: COF criteria:
■ Physical condition M Health and safety of the public and
■ Performance employees
Financial impact on utility
■ External and internal physical factors
affecting the asset K Public confidence
■ 0&M protocols and maintenance M Environmental compliance
■ System reliability
The tiered and adaptive plan(TAP)for condition assessment described in the subsequent sections focuses
on the LOF criteria for the pipe asset with an emphasis on the physical condition of the pipe.This TM is
based on a TAP for the condition assessment approach.

Task 1 Draft Buried Pipeline Condition Assessment Plan
3.5 Pressure Pipe Asset Tiered Condition Assessment Approach
A tiered approach for assessing pressure pipelines and their associated appurtenances is described in the
following subsections.The tiered approach is based on an assessment of the known common modes of
failure and on current available data.This approach balances risk with inspection costs and cannot
completely guarantee that any and all potential failures are accounted for.Continued forecasting,
maintenance plans,and budgets should still include provisions for responding to intangible events and for
implementing needed repairs.The concept behind the tiered approach is illustrated on Figure 3-5 and is
further described in the following subsections.

3.5.1 Tier 1 —Pressure Pipe Inspection
Tier 1 pressure system inspections include the topside evaluation of the pipes,valves,vaults,
appurtenances,and soil properties(corrosivity)along the alignment.Tier 1 pressure system evaluation
should be performed by a knowledgeable engineering professional(for example,an MWMC engineer or
an engineering consultant)in consultation with a NACE(National Association of Corrosion Engineers)
certified engineer.The Tier 1 evaluation would include the knowledgeable engineering professional
walking the pipe alignment,accompanied by WPCF 0&M personnel.Municipalities may not have the
engineering expertise to conduct a Tier 1 inspection;therefore,they may hire an engineering consultant to
perform the inspection to identify higher risk pressure assets.As the Tier 1 pressure pipe condition
assessment does not follow a standardized approach (such as NASSCO PACP),it is recommended that an
engineer with condition assessment and/or pipe corrosion experience perform this assessment to identify
subsequent inspection needs and frequency for assets.The NACE certified professional need not perform
the inspection;however,they should review findings and recommendations.
The evaluation by the engineering professional would include logging observations that serve as key
indicators of asset LOF,such as soil corrosivity(via soil resistivity measurements),the condition of assets in
vaults,communication with an WPCF representative of historic O&M,and past pipe failures.These
observations would generally provide qualitative findings with regard to asset condition rather than direct
measurements of pipe physical features that might be measured in subsequent tiers. For example,soil
resistivity measurements may indicate a higher likelihood of external pipe corrosion of metallic pipes for
certain pipe regions over other pipes of similar material and age.Additionally, internal pipe wall loss may
PPS0924201644CVO 11
Task 1 Draft Buried Pipeline Condition Assessment Plan
be indicated by air release valve vaults showing signs of corrosion due to elevated presence of hydrogen
sulfide gas.The corrosivity rating based on soil resistivity measurements are displayed below in Table 3-5.
Table 3-5. National Association of Corrosion Engineers Soil Corrosivity Ratings(Peabody,2001)
Soil Resistivity(ohm-cm) Corrosivity Rating
<1,000 Extremely Corrosive
1,000 to 3,000 Highly Corrosive
3,000 to 5,000 Corrosive
5,000 to 10,000 Moderately Corrosive
10,000 to 20,000 Mildly Corrosive
>20,000 Essentially non-corrosive
Tier 1 assessments include the exterior pipe and appurtenance condition,where exposed. For a pressure
pipe crossing a bridge,this may include documentation of corrosion and physical condition of the pipe
and hangers. For plastic or non-ferrous Large diameter pipes transient pressure monitoring may be
considered. For high consequence small diameter plastic or non-ferrous pipes,the assets may need to be
elevated directly to Tier 2 assessment.
Pipes that may be considered for Tier 2 assessment,based on Tier 1 observations,may include:
■ Pipe sections where considerable corrosion is observed at vaults.
■ Ferrous metal and concrete pipe sections located in moderately high to high corrosive soils.
■ Higher risk pipe assets based on location,diameter,and/or age relative to the expected age of the
pipe.
Tier 1 pressure assessment information is summarized in Table 3-6 below.

Task 1 Draft Buried Pipeline Condition Assessment Plan
Smart pigs are launched within the pipeline with a controlled flow rate,and take direct pipe wall thickness
measurements along the full alignment.The Tier 2 technologies typically measure average wall thickness
over sections of the pipeline,whereas the smart pig takes direct pipe wall thickness measurements at all
Locations along the alignment.This may be a costly technology to deploy if pipe modifications are
necessary to allow for launch and retrieval for the pig,as well as for the specialized postprocessing of the
data. Figure 3-6 shows a schematic of a launch configuration for smart pigs with an offshoot and
supplemental water supply to propel the pig down the pipe alignment.
Additional Tier 3 inspection technologies to be considered may include fiberoptic monitoring (3rd party
strike warning system),SeeSnake in-line inspection tools for measuring wall thickness and pitting,and
other Hine free swimming or tethered inspection tools.

Table 3-8.Tier 3 Pressure Pipe Assessment Summary Table
Category Description
Limitations ■ Tier 3 assessment technologies are costly and should be
considered as predesign for rehabilitation or replacement
rather than for traditional condition assessment purposes.
■ Specialized vendor technologies are performed by a limited
number of entities and may be subject to long lead times for
performing inspections and processing data.
3.6 Converting Assessment to Action
At each condition assessment tier,the observations should be used to inform the O&M plan for an asset. If
a new pipe asset is observed to be in excellent condition based on the Tier 1 assessment,the asset may be
categorized as in good condition and assigned the lowest frequency of follow-up inspections. Based on the
Tier 2 assessment,if a gravity asset is found to be in good condition structurally,but subject to root growth
atjoints or laterals,it may be considered for more frequent inspection and root management.If the Tier 2
or 3 assessment identifies an asset as failing, a business case evaluation may be performed to see if
rehabilitation or replacement is the more appropriate option.After this step has been performed for all
assets,the relative risk based on LOF and COF of each asset may be compared to prioritize capital
expenditures for asset renewal.
4. Next Steps
Implementation of the TAP for condition assessment for the MWMC should be performed as described in
the preceding sections.Throughout the process,at the end of each inspection tier,the MWMC should
consider what value is being added by performing the next phase of the assessment.A summary of the
steps for implementation is included herein.
■ Tier 0—Gravity and pressure:
— Finish compiling a database of existing asset information.
— Evaluate pipe assets with regard to consequence and LOF,to identify assets with elevated risk
profiles.
■ Tier 1 —Gravity:
— Determine whether condition assessment technologies are to be deployed internally or via a
contractor;procure inspection equipment and obtain staff training.accordingly.
■ Tier 2—Gravity:
— Determine whether condition assessment technologies are to be deployed using internal staff or
via a contractor;procure inspection equipment accordingly.
— Determine desired pipe condition assessment methodology(PACP or other).
— Perform Tier 2 assessments for assets elevated from Tier 1.
■ Tier 3—Gravity:
— Deploy specialized Tier 3 assessment technologies,as determined appropriate based on Tier 2
observations.
