Once the RDI/I and total volume of rainfall are calculated, the R-factor is a simple calculation of RDI/I volume divided by rainfall volume, resulting in the estimated portion of rainfall that enters the wastewater collection system. These values were also iteratively adjusted during the model calibration process.

7.4.4 Wet Weather Calibration
To initiate the wet weather calibration process, the observed rainfall collected at both rain gauges for Storm event 1 was added to the model (see Figure 7-12). During the calibration process, it was noted that the peak flows for all valley floor sub-basin meters occurred approximately three hours prior to the peak rainfall, which was clearly elevated related to rainfall as compared to dry weather flow. It appears that there may have been an error in the timestamps of RG01, so the rainfall was shifted three hours earlier.

Wet Weather GWI
GWI fluctuates over the course of the year, increasing during the wet season as the water table rises. The extent that the water table rises and falls is site specific and can be affected by geology, surface water features, and tides. By extension, wet weather GWI changes are also site specific and can also depend on the condition of the pipelines. In the wet weather calibration scenarios of the model, GWI values established during the dry weather calibration process were iteratively increased to reflect the elevated water table more accurately during the wet season as displayed by an increase in the minimum flows.

RDI/I R-Factor
The RDI/I is estimated using the R-factor, or the percentage of rainfall that enters a sewer system as described in Section 7.4.1, and the Tri-Triangular Method. The Tri-Triangular Method, which is the industry standard for representing wet weather flows, involves summing three separate hydrographs to derive a single unit hydrograph. The total R-factor is divided into three separate values, represented as triangles (see Figure 7-13), based on the speed at which rainfall enters the sewer system, as described below:
 Rapid (R1) – Stormwater inflow that enters the sewer system most rapidly, typically through entry points such as holes in manhole covers. The peak of this triangle occurs one to three hours after the start of the rainfall.
 Intermediate (R2) – A combination of rapid stormwater inflow and slow rainfall-dependent infiltration.
 Slow (R3) – Long term delayed rainfall-dependent infiltration. The peak of this triangle occurs the longest time after the start of the rainfall, and the effects of this infiltration can continue long after the end of the rainfall.

Figure 7-13: Tri-Triangular R-Factor Method
The initial estimated R-factors (R1, R2, and R3) for each sub-basin were input into the model, which generated the total R-factors. Total R-factors are simply the sum of the individual R-factors (R1 + R2 + R3). The entered R-factors were iteratively adjusted for each sub-basin by comparing modeled flows to observed flows at each flow meter during the day of, and the two days following, the storm. During this part of the calibration process, it is critical to capture the peak flows as accurately as possible to avoid underestimating capacity deficiencies.

The final calibrated R-factors for each sub-basin are presented in Table 7-8.

For wet weather calibration of the system, average modeled flows representing Storm event 1 and one day following the storm are 3.3% higher than measured flows. Modeled peak WWF for Storm event 1 are 2.3% higher than measured peak flows. A calibration within 5% is considered a good representation of actual conditions and having modeled flows higher than measured flows assures that the model is conservative in its representation of the collection system.

A sample wet weather calibration chart is displayed in Figure 7-14. Wet weather calibration charts for all flow meters are attached as Appendix E.

Notes:

1. There is no flow meter at the outfall for sub-basin O. Values were estimated based on surrounding sub-basins.

2. The average represents the weighted average by sub-basin area.

In summary, total R-factors for each subbasin ranges from 0.24% up to 3.71%, which represents the percentage of rainfall entering the collection system. A low R-factor would be less than 3% and 10% is considered high. The weighted average for the entire system is 1.04%; this is considered a relatively watertight system with limited rainfall entering the collection system. 861

SECTION 8 – CAPACITY ANALYSIS
The hydraulic analysis for the collection system was evaluated under design storm for existing and future land use conditions. This section describes the analysis and the resulting deficiencies.

8.1 Design Storm
To estimate WWF, a design storm is applied to the model and wet weather flows are represented based on the calibrated R-factors for each sub-basin. A range of storms was considered for the design condition of this study. Both the 2002 and 2009 Master Plans used a 10-year, 4-hour constant distribution storm. Often, a 10-year 24-hour storm is used with a peak hour coinciding with the peak of the typical diurnal curve. A 5-year 24-hour storm was also available in the event that a 10-year 24-hour storm caused exceedingly large flows due to high rates of RDI/I.

For this study, the typical 10-year 24-hour storm with a peak hour coinciding with the peak of the typical diurnal curve was deemed appropriate.

8.2 Deficiency Criteria
The initial deficiency criteria used to evaluate the capacity of the modeled pipes under design flow conditions was the ratio of wastewater flow depth (d) to pipe diameter (D), or d/D. In InfoWorks, if d/D is greater than one, this means the pipe is flowing full under pressure and the hydraulic grade line (HGL) is higher than the crown of the pipe. InfoWorks also reports a “surcharge state” for each pipe, and Table 8-1 summarizes the definition of each surcharge state.

In the hydraulic model, the HGL reaching the ground surface indicates a potential SSO. Even for a pipe flowing under capacity or surcharged, if the freeboard – the distance between the ground surface and the HGL – is five feet or greater, the risk of SSO is minimal. Where pipes were shown as surcharged due to inadequate hydraulic capacity (surcharge state of “2”), a pipe was identified as deficient if the freeboard in these locations is also less than five feet.

Table 8-1: InfoWorks Surcharge States
Surcharge
State Definition Deficiency if:
< 1 1 When depth of flow is less than the diameter of the pipe Not considered hydraulically deficient
= 1 Pipe is surcharged due to backwater from a downstream deficiency. Not considered hydraulically deficient
= 2 Pipe is hydraulically under capacity and needs to be upsized. Freeboard < 5 feet Notes:

1. Surcharge State = d/D

8.3 Assumed Condition
As detailed in Section 7.3.4, there were three critical flow splits identified in the system as having major flow obstructions that drastically changed the flow path of wastewater – likely from grease buildup at MH 539, MH 543, and MH 2488. During the dry weather calibration process, these flow splits were modified in the model to match the wastewater flows observed in the system. For the hydraulic analysis, system performance was evaluated based on the assumption that these obstructions have been cleared and the system is operating as intended.

8.4 Future Condition
Section 5.2 presents the process used to update the land use for potential future redevelopment areas in the City to estimate future wastewater flows. For the hydraulic analysis of the system under future conditions, calibrated GWI, UF factors, and R-factors developed above were applied to the updated land uses for projected future buildout conditions. The same design storm was used for both existing and future conditions.

8.4.1 Large Dischargers
If parcels were identified as large dischargers under existing conditions and located within “Opportunity Areas” (see Figure 2-2 and Figure 5-2), the existing land use was compared to the future land use; where the land uses differed, the future land use UF factor was applied. If there 865

was no change to the land use, then the large discharger wastewater flow (see Table 7-5) under existing conditions was maintained for the future scenario.

Table 8-2 lists the large dischargers that were removed from the future condition and replaced with the future land use UF factors.

Notes:

1. Source: January-March 2019 water meter customer billing data provided by the City multiplied by 85% - assumed portion of water use that contributes to wastewater flows.

Los Esteros Ranch, which is located at the intersection of McCarthy Blvd and Dixon Landing Road, is connected to the City collection system. This land use was added to the modeled system in accordance with the City’s agreement with Los Esteros Ranch. The agreement between the City and Los Esteros Ranch, attached as Appendix F, states that they have a maximum allowable water usage of 50,000 gpd among the three parcels included in the agreement. Applying the same method identified for other large dischargers (see Section 7.3.2), it was assumed that wastewater flows constitute approximately 85% of water usage. Los Esteros Ranch was assigned a wastewater flow of 42,500 gpd and was added as a large discharger for the future condition.

The area of the three contributing parcels was measured using the Measure tool in Bluebeam Revu 2016 and calibrated using the scale bar displayed on Exhibit “A” of the Los Esteros Ranch Agreement.

8.5 Hydraulic Capacity Deficiencies
Under dry weather conditions, Table 8-3 shows a 6% increase to 7.9 MGD in average flow for future conditions at the outfall.

Under all scenarios, there were no additional surcharged segments identified under future conditions that were not seen under existing conditions. It is expected that this is because the City is largely built out and system improvements implemented with development have addressed potential deficiencies.

There were six pipe segments with a recorded surcharge state of “2” (see Section 8.2) under both existing and future conditions indicating that they are under capacity. These segments are displayed on Figure 8-2. Provided below is a description of each of these pipelines:
 Surcharged Location 1: This pipe segment drops below the minimum freeboard deficiency criteria (see Table 8-1) with a freeboard of 4.7 ft, shown in Figure 8-3. For a single pipe reach, replacement is not recommended without further cause. It is recommended that the City monitor this location for surcharging. This location (MH GID 1392) is a good candidate for installing a SmartCover to monitor the wastewater level and prevent SSOs.  Surcharged Location 2: These two surcharged segments are 6-inch mains. Freeboard at these locations is greater than five feet, so they do not exceed the criteria for a capacity deficiency and therefore are not considered deficient. In general, it is recommended that all future sewer mains in the collection system are constructed with minimum diameters of 8- inches.

 Surcharged Location 3: These two surcharged segments are 10-inch pipes. Freeboard at these locations is greater than five feet, so they do not exceed the criteria for a capacity deficiency and therefore are not considered deficient.
 Surcharged Location 4: This pipe, identified as under capacity (GID 17506), is located to the west of the intersection between N. Milpitas Blvd. and Washington Dr. In GIS, this segment was identified as an 8-inch pipe; however, both upstream and downstream pipes were identified as 12-inch pipes. During the review of record drawings, it was unclear if this pipe has been upsized to match the neighboring pipes. In the model, this segment experiences surcharging during wet weather as an 8-inch pipe, however, when this segment is upsized to 12-inches to match the neighboring pipe diameters, there is no longer surcharging. An improvement project is not recommended at this location as the freeboard is over ten feet and does not meet the threshold for deficiency identified in Table 8-1. 869

SECTION 9 – PROJECT DEVELOPMENT
Based on the condition assessment described in SECTION 4, projects were recommended to address prioritized defects identified in the collection system. This section describes the prioritization process and a summary of the project cost development. Results of this project development and selection translate into a prioritized CIP for the wastewater collection system.

9.1 Rehabilitation Selection Methodology
The PACP peak scores from the CCTV inspection and the risk scores calculated from the LoF/CoF desktop condition assessment drive the pipeline rehabilitation selection process. Below is a summary of the methodology implemented for both inspected and non-inspected pipe.

9.1.1 CCTV Inspected Segments
For segments with CCTV inspection data, a two-step process was used to determine the final rehabilitation recommendation. Using the defect coding assigned by NPS and the IAP software, the pipe segments with defects were assigned one of the following defect-level rehabilitation methods:
 Replace;
 Cured-in-place pipeline (CIPP);
 Point repair by excavation; or
 Sectional liner.

When the user assigns a rehabilitation method for each defect code, IAP assigns the respective rehabilitation method to each segment based on the associated defect coding.

Table 9-1 presents a sample of the assigned rehabilitation methods for all structural defects with a score of 5. A full list of all defect codes and associated rehabilitation methods can be found in Appendix A (R&R Study App. H).

With the rehabilitation method established for each defect code, a decision tree was established to determine the final overall rehabilitation method for the pipeline. This decision tree was prepared based on the following factors:
 CCTV structural peak score and overall peak score;
 Number of point repairs and lining recommendations by the defect-level rehabilitation methods module;
 Number of defects;
 Length of major (score of 4 or 5) and/or minor (score of 3) defects; and  Presence of specific defects such as infiltration drippers (ID) or Reinforcement Corroded Chemical (SRCC).

www.hydroscience.com
Figure 9-1 presents a schematic of the established decision tree. Pipeline segments with CCTV inspection data are filtered by their PACP peak scores. Then, they are analyzed based on the number of point repairs and lining recommendations established by the defect-level rehabilitation methods module as well as the number of defects, length of defects, and presence of specified minor, but not negligible, defects. When multiple rehabilitation options were recommended, a cost analysis was performed to determine the best action. For example, if a segment was recommended to receive ten sectional liners, a full liner would be more cost-effective.

Figure 9-2 displays the final rehabilitation methods recommended for each segment based on the decision tree. For a table of the recommended rehabilitation method for each segment, see Appendix A (R&R Study App. A).

9.1.2 Segments without CCTV Inspection
For segments without CCTV inspection data, risk scores and diameter were used to develop a prioritized set of segments that are recommended for CCTV inspection and further analysis.

Pipeline segments with a risk score of medium or higher (greater than or equal to three) – see Section 4.2.3 – were included as part of this CCTV recommendation. Additionally, all pipelines with a diameter of 24-inches or greater are recommended for prioritized CCTV regardless of the associated risk rating. Figure 9-3 presents the segments recommended to prioritize for CCTV. 871

9.2 Basis of Cost Assumptions
A cost estimate was developed for each type of rehabilitation method. Provided is a description of the basis for unit cost development and associated project-specific costs for pipelines, resurfacing, manholes, pumping systems, structural rehabilitation, protective coatings, bypass and redundancy, and electrical equipment. The purpose of approximating construction costs is to appropriate a conservative level of funding for each identified rehabilitation project included within the proposed scope of the City’s upcoming CIP. Appendix A (R&R Study App. J) contains details of the preliminary cost estimates for all projects analyzed as part of this SMP.

9.2.1 CCTV Costs
CCTV costs were estimated based on diameter and length. Unit costs are conservative to account for the added cost for specialized techniques, such as laser profiling for large diameter pipe, and general quality control review. Unit costs are provided in Table 9-2.

Table 9-2: CCTV Unit Costs
Pipe Diameter (in) Unit Cost ($/ft)
Up to 18 $4
19 to 24 $5
25 to 36 $6
37 to 66 $8

9.2.2 Pipeline Costs
Pipeline construction costs were developed in coordination with the City according to the City’s cost criteria.

9.2.3 Soft Costs
Soft costs are additional project costs that are not considered to be contractor construction costs.

These costs include engineering design, permitting, construction administration, and construction management. Typical soft costs include the following:
 Engineering design and consulting is expected to also address California Environmental Quality Act (CEQA) requirements to identify significant environmental impacts, if any.  Permitting, land acquisition and obtaining right-of-way (ROW) are dependent on the project.

For existing City facilities, the cost is expected to be less than if an easement is needed to be obtained through a property. The cost is also expected to be a function of the total cost. A range of percentages were applied to each project.
 Engineering services during construction (ESDC) and construction management costs are those costs associated with the administration of the contract and management of the project, ensuring the project is constructed as designed.
 The annual inflation of cost that would occur over time for a future project. 875

Sewer CIP are largely funded by the Sewer Infrastructure Fund. Other funding sources include the Sewer Fund (user rate structure) and the Sewer Treatment Fund (sewer connection fees).

The funds are described in the CIP 2020-2025 Final Report as follows:
 Sewer Infrastructure Fund: Monies set aside to replace aging infrastructure for sewer related projects.
 Sewer Fund: Enterprise fund which receives revenue from sewer rates for sewer related improvements.
 Sewer Treatment Fund: Funded from fees collected from developers connecting to the Sewer System. Funds restricted for sewer related projects.

10.2 Proposed CIP Projects
Three alternatives to project phasing were evaluated in developing the proposed CIP phases.

The first alternative addresses CIP projects based on BRE grades without consideration of project location, prioritizing the highest risk projects. The second alternative approach groups projects geographically within the sewer basin. The third alternative, which was selected for implementation, was a hybrid approach where pipelines with significant defects were prioritized in the first year and each subsequent year considered risk, type of rehabilitation, and geographic location. The general strategy is to address the highest risk/highest priority projects in the nearterm (Years 1-5) with lower risk projects deferred to the medium- (Years 6-10) and long-term (Years 11-20). The objective was to budget for approximately $1.5M-$2M annually. Depending on funding availability, projects can slide up or down CIP phases while maintaining project priority. 879

The detailed risk assessment, basis for selecting rehabilitation methods, prioritization of improvements, and the related construction costs (construction and contingency) are provided in Appendix A (R&R Study).

Soft costs, as described in Section 9.2.3, consisting of engineering design and consulting; permitting and ROW; and ESDC, construction management and inspection services are included in the capital project costs provided. The following sections present the recommended projects for implementation and the proposed timeframe.

10.2.1 CCTV Inspection
Approximately 105,000 ft (449 segments) of sewer main was inspected as part of the condition assessment. The remaining 685,000 ft was analyzed using the desktop assessment. Mediumto extreme-risk pipes and large diameter pipes are recommended for CCTV inspection. Large diameter pipe is defined as 24-inch diameter or greater. Figure 9-3 presents the recommended CCTV inspection map of these highest priority areas. These inspections total 55,000 ft, with an estimated cost totaling approximately $400,000 based on the unit costs provided in Section 9.2.1.

It is noted that the CCTV inspection work may generate additional improvement projects that may augment the proposed CIP. There is an existing CIP project (6126) that is intended to address minor sewer projects that currently allocates $50,000 annually. It is recommended that the City increase the annual allowance to $250,000 ($1.25M every five years) to budget for improvements needed to address defects as they are discovered during new CCTV inspections.

10.2.2 Pipeline Improvements
Of the approximately 105,000 ft (449 segments) of sewer pipeline inspected, approximately 50,000 ft (178 segments, see Figure 9-2) requires improvement. Recommended improvements include:
 Pipe Replacement
 Full Cured-In-Place Pipe (CIPP)
 Point Repair(s) by Excavation
 Sectional Liner(s)
It is noted that some pipeline segments include more than one recommended rehabilitation method.

10.3 CIP Budget and Schedule
The sewer CIP is funded by the sewer enterprise fund which includes the user rate structure and sewer connection fees. Provided below in Table 10-9 is a proposed budget and schedule for the CIP and recommended projects over 20-years in 5-year increments. The most critical projects are scheduled for earlier implementation. It is noted that the timing of projects can be adjusted based on results of CCTV and future operating conditions. Figure 10-1 presents the proposed improvement projects in 5-year increments.

1. Original allocation is $200,000 through 2023 with $148,000 in prior year funding from Sewer Infrastructure Fund to be allocated for other projects in FY2020-21.

2. Original allocation is $200,000 with $37,000 in prior year funding from Sewer Infrastructure Fund to be allocated for other projects in FY2020-21.

3. It is noted that costs were reviewed and updated during 2022 to reflect recent cost increases associated with sewer infrastructure projects.

After the projects above were developed, the City contracted with the financial consulting firm Raftelis to develop fiscal impact models and to assess the financial feasibility of the Master Plan projects, beginning FY 2024 through FY 2040. The financial models are intended to evaluate the sewer utility fund revenues and expenses and analyze the impacts of the Master Plan projects on City funds. The Wastewater Financial Plan Options Report is attached as Appendix G.

10.4 Other Recommendations
During the CCTV inspection performed by NPS, there were instances of large grease buildup in various locations throughout the wastewater collection system. As explained previously, the presence of grease buildup and other blockages, particularly at, or near, critical flow splits, can significantly impact collection system operations, particularly at flow splits, which are generally intended to mitigate high flows and provide redundancy. This redundancy aids the system’s ability to handle higher flows during wet weather events and as the water table rises during the wet season. When flow splits are not operating properly, this can drastically impact the system operation, particularly during wet weather events.

It is recommended that the City cleans the locations identified as having grease buildup.

Locations should also be vacuumed to remove blockages from moving further downstream. In addition, stricter FOG Control Program guidelines and increased inspections may be necessary to prevent FOG discharges to the wastewater collection system.

It is expected that there will be additional O&M costs related to the following:
 In-house CCTV inspection;
 Additional cleaning related to the act of inspection and as a result of discovering blockages; and
 Implementing a stricter FOG Control Program/increased inspections of grease traps.

In addition to the projects summarized herein, the City is evaluating the need to rehabilitate or replace Force Main A (FM-A), which conveys wastewater from the Main LS to the RWF (see Figure 3-1). Built in 1974, FM-A was identified as requiring inspection because the soils surrounding the pipeline are very corrosive. The City contracted with a third party to perform cleaning and CCTV inspection of FM-A to determine the internal condition. The inspection was not fully completed due to unforeseen obstacles.

It is recommended that the City perform a complete condition assessment of FM-A to verify the internal condition of the pipeline and determine the best options for rehabilitation or replacement.

The City’s report generated by the engineering department is included as Appendix H.

Initial City estimates to rehabilitate or replace FM-A are approximately $1M to complete the force main assessment and maintenance of the appurtenances and an additional $25M to replace the force main. Both of these costs were included as capital projects requiring consideration for an upcoming CIP, in addition to the amounts specified in Section 10.3. 889

Sewer Utility Asset Renewal and Replacement Study
6 Executive Summary
As a part of the City of Milpitas’ (City) Sewer Master Plan, Brown and Caldwell (BC) has been retained to develop a Sewer Utility Asset Renewal and Replacement (R&R) Study. The intent of the R&R Study is to provide the City with priorities for upcoming asset renewal and replacement projects given a fixed yearly budget.

Closed-circuit television (CCTV) was utilized to visually assess the sewer’s condition. Resulting CCTV review was summarized and cataloged according to National Association of Sewer Service Company’s (NASSCO) Pipeline Assessment and Certification Program (PACP) structural and operations and maintenance (O&M) grades in Section 2. Additionally, a desktop condition assessment was performed for all pipe segments using likelihood of failure (LOF) and consequence of failure (COF) criteria described in Section 3. This collective analysis revealed that of the approximately 105,000 linear feet (LF) (449 sewer segments) of sewer gravity pipeline inspected, approximately 50,000 LF (178 sewer segments) require system improvements totaling approximately $17 million of construction costs. Of the remaining 685,000 LF segments with no inspection data, desktop risk assessment determined that 55,000 LF of medium to extreme risk pipes and/or large diameter pipes (24-inch diameter pipe or larger) require CCTV or sonar inspection totaling approximately $400,000. System improvements and CCTV inspection recommendations total to $17.4 million. These proposed improvements are illustrated on Figure ES-1.

Pavement repair assumes minimum four-foot-wide trench per running foot. 2Contingencies amounting to 45% are included in the estimate (5% Mobilization/Demobilization, 10% Sewer Bypassing, 30% Construction Cost and Market Contingency). Additionally, traffic control during construction amounting to $10,000 to $30,000 depending on roadway traffic rating was also assumed. Administrative, engineering, or other planning costs typical of CIP planning are not included.

These rehabilitation recommendations are divided into capital improvement program (CIP) phases below in Table ES-2 in correspondence with the City’s $2,000,000 annual rehabilitation budget when feasible.

Although years 2 and 3 propose rehabilitations exceeding the budget, crucial rehabilitation of extreme and select high risk pipes help to minimize costly pipe failures. In addition, years 4 through 8 feature a rehabilitation plan requiring less budget to offset the previous expenditures.

3 Section 1: Introduction
The intent of this Sewer Utility Asset Renewal and Replacement (R&R) Study is to provide the City of Milpitas (City) with priorities for asset renewal and replacement. A part of the evaluation included developing an understanding of the relative risk of failure for the City’s sewer gravity pipeline segments by performing a likelihood and consequence of failure analysis. Understanding the relative risk of failure for various sewer pipeline sections is critical to effectively plan sewer capital improvement projects by prioritizing the highest risk projects. Brown and Caldwell (BC) worked closely with City staff and HydroScience Engineers (HSE) to develop an appropriate failure ranking and weighting system to predict risk of failure. In general, overall risk of failure was determined by considering both pipe characteristics (age, material, depth, location, presence of obstructions, etc.) and internal pipe video inspection findings.

1.1 Background
The City of Milpitas is located within the San Francisco Bay Area, north of San Jose, California. All wastewater produced in the City is treated at the San Jose–Santa Clara Regional Wastewater Facility (RWF), the largest advanced wastewater treatment facility in the western United States. The City’s sewer system serves over 77,000 customers and consists of 0.95 million linear feet (LF) of underground pipeline, including 26,400 LF of force main pipeline (Milpitas Wastewater Fact Sheet, Water and Sewer System Information). Wastewater is conveyed to RWF through two large pump stations, the Venus station and the Main Sewer pump station (Milpitas Wastewater Fact Sheet). A map of RWF’s tributary agencies, provided by the City of San Jose, can be found in Figure 1-1 (City of San Jose). Recycled water, which is produced at RWF, is returned to the City for use in non-drinking water applications, such as irrigation of golf courses and agricultural land. Recycled water pipelines, shown as purple pipes in Figure 1-1, are not included in this analysis.

5 Section 2: Inspection Condition Assessment
Understanding the internal pipe condition (presence of structural and operational & maintenance (O&M) defects) is critical to understanding asset condition and likelihood of failure. Closed-circuit television (CCTV) inspection was utilized to assess the internal condition of the key pipeline segments. Key pipeline segments were defined as follows:
• Diameters greater than 8 inches
• Located within traffic impacted areas
• Located within commercial/industrial areas.

Due to budget limitations, the CCTV efforts were divided between a subcontractor, National Plant Services, Inc (NPS), and the City. NPS completed their portion of CCTV inspections between March and May of 2020.

The City was unable to complete its portion of the CCTV inspection due to Coronavirus restrictions, therefore that portion of the information was not available for this analysis. Approximately 105,000 LF of CCTV inspection data was collected by NPS.

2.1 Planned Segments and Scope
NPS’ work was subdivided into six planned inspection contracts shown in Table 2-1. Figure 2-1 details the division of the contracts, as well as the sewer segments scheduled to be inspected by the City. The detailed planned CCTV inspection scope can be found in Appendix B.

In addition to CCTV, a two-dimensional laser and sonar inspection was to be performed as part of Contract Trunk 1. Due to scheduling conflicts, this work was not completed.

2.2 Inspection Results (NPS)
NPS successfully inspected 105,221 LF of their contracted 122,330 LF of sewer pipeline. NPS reported that pipes were unable to be completely inspected for multiple reasons, including presence of siphons (requiring extra equipment), root balls, grease, rocks, and other debris preventing complete inspection. The inspected segments are shown in green on Figure 2-2.

2.2.1 Defect Coding
The National Association of Sewer Service Company’s (NASSCO) Pipeline Assessment Certification Program (PACP) was utilized to assess sewer pipeline condition and identify defects. All pipeline segments were coded by NPS staff who had been PACP-certified. Additionally, approximately 20 percent of the pipe (89 out of 449 pipe segments) CCTV and PACP reports were reviewed by PACP-certified BC personnel, as part of BC’s quality control (QC) process. BC noted minor issues with the condition assessment data collection or data review and forwarded summary of this review to HSE. Further details regarding the QC process can be found in Section 2.3.

The condition assessment of pipelines consists of:
• Identifying defects along each pipeline segment through visual inspection • Assigning individual grades to each defect based on the type and severity • Developing an overall Condition Grade for each pipeline segment by assessing type and number of defects along the pipeline segment
• Assigning a final Condition Rating to each pipeline segment based on the condition grades and the potential for further deterioration and/or failure
Under PACP, defects are categorized as either structural or O&M related. Structural defects are those that directly impair the structural condition of the pipeline, such as joint separation, joint deflections, cracks, fractures, broken and collapsed pipe or wall, corrosion, worn inverts, and sag conditions. Structural defects are those that are typically addressed through repairs, rehabilitation, or replacement. O&M defects include a range of conditions that can either directly affect the performance of the sewer or are indicators of potential future structural defects. O&M conditions include debris, grease, infiltration, intrusions (root or service laterals), and hydraulic problems. O&M defects are typically addressed through maintenance, although some (such as infiltration) may require additional rehabilitation.

In general, PACP grades range from 1 to 5, with 1 being a minor defect grade and 5 being the most significant defect grade. Table 2-3 provides a description of the defect related to the condition grade it receives. 906

2.3 Quality Control Review
Following CCTV inspection, the CCTV database was imported into InfoAsset Manager (IAM) to compare CCTV data to existing geographic information system (GIS) data. After the import, several QC queries were performed to confirm that CCTV data was appropriately matched with existing GIS data. For example, a conflict between CCTV data and GIS data can occur when a new structure is found in the field, or when a structure in the GIS is verified to not to exist on CCTV. Once QC in IAM was completed, the data with updated manhole and pipe connectivity (as confirmed by CCTV) was exported for use in InfoAsset Planner (IAP). Updated GIS data was made available for HSE to update their model and maps.

The QC review of CCTV and PACP reports was performed on approximately 20 percent of the pipe segments.

In general, several videos were found to be blurry or unfocused. These were noted in the QC Comment Log, included as Appendix C. Primary QC efforts targeted pipe segments with structural peak grades of four or five because of the high likelihood of these segments requiring repair or improvements. Pipe wall loss due to corrosion, of varying severities, was found throughout the collection system, which is not unexpected in sanitary systems comprised of concrete pipes. Infiltration was observed in some locations, and a few pipe breaks and holes with visible voids were identified. Specific QC comments can be found in the QC Comment Log (Appendix C).

12 Section 3: Desktop Condition Assessment Task
For all pipe segments, a desktop condition assessment analysis was performed to assess asset risk. The overall risk of pipeline failure is determined by considering both the likelihood that an asset is unable to provide the function for which it was installed, as well as the consequence or impacts resulting from failure of the asset.

Overall likelihood of failure (LOF) and consequence of failure (COF) scores were determined by considering both factor ratings and factor weightings. The LOF factor rating predicts how likely an asset is to fail and the consequence factor rating predicts how consequential an asset failure would be. Assigned factor ratings range between one and five, with one being the least likely to fail/least consequential and five being the most likely to fail/most consequential.

The likelihood/consequence factor weighting is an assigned value which reflects the relative importance of a specific factor category compared to other factor categories. Critical factors are assigned greater weighting values than less critical factors.

The following equations provide basis for determining risk scores.

3.1 Likelihood of Failure
The LOF analysis predicts the likelihood that an asset is unable to provide the function for which it was installed determined by assigned ratings and weightings. The factors selected for analysis are typical for sewer renewal/replacement projects.

Asset characteristics, asset condition and asset location were all considered during the LOF analysis. In all cases, unknown data was assigned medium risk. Specifically, the following factors were used (data sources included in parentheses):
• Pipe Age - In general, as a pipe ages, it has a higher likelihood to fail (pipe age provided by City GIS). • Pipe Material – Different pipe material has different life expectancy and failure modes (pipe material provided by City GIS).
• Structural Condition, if available – Known structural defects based on 2020 CCTV survey performed by NPS.
• Presence of Pipe Obstructions (roots, grease, debris, infiltration, etc.), if available - Known O&M related defects based on 2020 CCTV survey performed by NPS. • Required Pipe Cleaning – Pipes requiring higher cleaning frequency oftentimes experience problems when not maintained. However, the act of cleaning (with high pressure jets of water at a minimum) can cause premature failure and inadvertently remove the top layer of potentially corroded concrete or metal pipe (cleaning frequency provided by City).

Risk = LOF Score x COF Score
LOF Score = ∑ (LOF Rating x LOF Weighting) COF Score = ∑ (COF Rating x COF Weighting) 910

13 • Proximity to Landslide Zones - Landslides can pose a threat to pipe segments which are surface pipelines or buried at a depth of three feet or less (Baum, 2008). This factor also accounts for the impact of smaller seismic events on pipe structural integrity ((Landslide Zone) County of Santa Clara Department of Planning and Development).
• Proximity to Earthquake Faults – Pipes located in the Hayward Fault zone are rated higher likelihood to fail. This factor also accounts for the impact of smaller seismic events on pipe structural integrity ((Fault Zone) County of Santa Clara Department of Planning and Development). • Local Geology (Liquefaction) – A liquefaction layer from County GIS provides soil resiliency ratings to seismic events. This factor accounts for the impact of smaller seismic events on pipe structural integrity ((Liquefaction Rating) County of Santa Clara Department of Planning and Development).

Details and scoring basis for each factor are elaborated in Table 3-1.

3.2 Consequence of Failure
The COF analysis predicts the impact resulting from the failure of an asset by assigned ratings and weightings. Service interruptions, repair/overflow potential, transportation/transit, response time of potential failure, cost of potential failure, and environmental impacts were all considered during the COF analysis.

In a similar fashion to the LOF analysis, the factors selected for analysis are typical for sewer renewal/replacement projects and were selected to ensure the pipe rehabilitation prioritization aligned with City Council core values and priorities. The COF and City Council core values and priorities are shown in Table 3-

2. Certain consequence factors, such as pipe diameter or road type, quantify multiple council core values. As a result, these factors received a higher factor weighting value.

Waterway/waterbody
(proximity)
Due to public health and environmental concerns, the potential for waterway/waterbody leaks and road type were weighted most heavily followed by pipe diameter and access restriction. Additional COF factor descriptions and data sources are provided below:
• Sewer Size (Pipe Diameter) – Larger diameter pipes are more expensive to replace and provide a greater service area than smaller diameter pipes (pipe diameter provided by City GIS). • Proximity to Critical Facilities – Pipe proximity to an educational, police, fire, or health facility was calculated and rated for COF. Facilities were searched from Google Maps and geocoded onto the ArcGIS platform. Pipelines servicing critical facilities were approximated by using a buffer of 500 feet. For context, the facility addresses were plotted as a point, so the buffer of 500 feet accounts for building size and nearby critical pipes.
• Road Type – Different road types such as arterial or highway will impact more people than a neighborhood street. Therefore, pipe intersections with major traffic conveyance routes such as the Bay Area Rapid Transit Milpitas station, freeways, state routes, arterial streets, or major roads were determined. The GIS used for major roads was downloaded from County of Santa Clara ((Major Roads) County of Santa Clara Department of Planning and Development). The BART GIS was downloaded from BART website and a buffer of 800 feet was applied to the geocoded coordinate point to capture the frontage and segments adjacent to the frontage. A buffer of 35 feet was applied to the major roads layer to capture potential overflow impact and GIS alignment differences between the road type and pipe layers.
• Railroad Proximity – Impacts to railroad operations and repairs on railroad property have significant cost and permitting impacts (railroad GIS provided by United States Geological Survey (USGS) (USGS National Transportation Dataset for California)).
• Easement (Access Restriction) – Access restrictions were determined by overlaying the city GIS over an aerial base map and manually assigning pipes which appeared to be in private property or restricted areas. For example, the parking lot of a shopping mall would be assigned private but not restricted. However, if a pipe is near a swale between a park and a neighborhood, or between two properties, it was assigned “restricted access”. In a further analysis, parcels with easement information could provide a more refined outcome. • Pipeline Depth – Calculated by subtracting pipe inverts from manhole rim elevations from City GIS. • Proximity to Waterway or Waterbody – Significant permitting impacts for repair or cleanup of failed pipe (waterway/waterbody GIS provided by USGS (National Hydrography Dataset, 2019)).

3.3 Asset Risk
Once the LOF and COF rating and weighting have been determined for individual factors, an overall LOF score and overall COF score can be determined by summing the factor scores. Multiplying the two overall scores determines the overall asset risk (Risk = LOF x COF). Asset risk is considered negligible, low, medium, high or extreme based on the paired LOF and COF data. The matrix below illustrates the risk assignments for varying LOF and COF pairings.

21 3.4 Staff Input
A risk assessment workshop between HSE, BC and City staff was conducted on April 24, 2020. The purpose of this workshop was to provide an overview of the risk assessment approach and to receive City input regarding specific risk assessment criteria and weighting. At this workshop the final LOF and COF criteria and weighting were reviewed. Following the workshop, BC sent a proposed criteria and weighting document, to which the City agreed on. Key comments were summarized below:
• Seismic events are fairly unlikely; use caution to weigh the proximity to earthquake faults factor too highly.
o Noted. City to confirm draft LOF and COF weighting shown in this draft report. • Bay Area Rapid Transit (BART) is very critical. This is regarding discussion of “road type/transit” COF factor.
o Draft report #1 comment - the addition of BART will be investigated in between draft and final report. o Final report - BART was added to the road type/transit COF factor and report content was revised accordingly. • City confirmed that repairs to pipe on freeway/highway is challenging. o Action - Incorporated in criteria. Pipes within 35 feet of freeways are assigned the highest COF factor for the road type.
• Sewer pipelines are relatively new, so it may be hard to provide much input on historical data. o Noted. CCTV survey and other desktop condition assessment factors will drive pipe rehabilitation and inspection recommendations. • City decided to rate pipes that would go directly to a waterway/waterbody higher. o Action - Incorporated in rating and weighting. Pipelines near waterway/waterbodies are rated by proximity. The factor measuring waterway/waterbody proximity was most highly weighted.

3.5 InfoAsset Planner (IAP)
A desktop risk assessment was performed using Innovyze’s IAP program, a GIS extension tool. Using the criteria described in Sections 3.1 and 3.2, LOF analysis predicts the probability that each asset could fail based on its GIS data and spatial interaction with other GIS layers. All assets, with or without CCTV data, were evaluated in detail using:
1) GIS data, such as age, material, and diameter
2) County or USGS GIS layers such as seismic hazards, soil stability, waterways, and other factors 3) Maintenance data - required pipe cleaning factor
4) CCTV data when available
For example, for the structural condition and presence of pipe obstruction LOF factors, CCTV data was analyzed to mass compute LOF for each of the approximate 3,200 pipes based on structural and O&M defects. Likewise, COF analysis determines the severity of each asset if it were to fail. The tool scores each pipe for COF based on asset data such as diameter and proximity to other GIS layers such as waterways or hospitals. Each LOF and COF factor is first set up in individual modules by choosing to use asset data, CCTV survey results, or spatial analysis with other GIS layers. Then, buffers and score criteria are defined. Once this is setup, the risk analysis takes user input for weighting of these factors relative to one another and 919

3.6 Risk Assessment Results
Overall LOF and COF score assignments were determined for all pipe segments, based on the criteria outlined in Tables 3-1 and 3-3. A total risk score was then determined from the product of the overall LOF and COF scores, which was then normalized within the dataset from one (negligible risk) to five (extreme risk).

• Blue – Negligible risk
• Green – Low risk
• Peach – Medium risk
• Magenta – High risk
• Dark Red – Extreme risk

26 Figure 3-11: Pipeline Risk Distribution by Length
For the pipeline risk distribution figure, the “blank” category is attributed to 22 pipes whose GIS segments had blank facility ID, diameter, installation date, and material fields. Table 3-4 below shows the pipe segments with the highest risk scores. This includes all pipes with risk scores of 4 or 5. Appendix F provides the risk scores for all pipe segments. LOF and COF scores are calculated based on the equation figure at the beginning of Section 3 and the rating and weighting criteria described in Table 3-1 and 3-3 in previous sections. The risk score column is calculated by multiplying the LOF score and COF score, which is then normalized from 1 through 5 in the last column (1- negligible, 2-low, 3- medium, 4- high or 5- extreme). The table is sorted by descending risk score.

34 Figures 3-13 and 3-14 summarize the LOF and COF drivers previously presented in Table 3-5.

Figure 3-13: Extreme Risk Pipes – LOF Drivers
Liquefaction susceptibility, pipe obstruction rating, and structural rating are among the most common LOF drivers of extreme risk pipes. That is, of the extreme risk pipes, these LOF factors reoccur most often.

Figure 3-14: Extreme Risk Pipes – COF Drivers
Proximity to waterways, large pipe diameter, and proximity to high traffic flow areas are among the most common COF drivers of extreme risk pipes.

35 In summary, a desktop risk analysis of all pipe segments revealed that pipe mains located along E Calaveras Blvd, N Milpitas Blvd, S Main St, I-680 (crossing), Machado Ave, Sylvia Ave, Cadillac Ct, S Abel Ave, Coming Ave, Sinclair Freeway, S Hillview Drive, Sinnot Ln, and Tramway Dr were rated to be high or extreme risk. Pipe segments considered high or extreme risk are at the greatest likelihood of deterioration and/or have the highest consequence of failing. As such, pipe rehabilitation and inspection for these pipelines are prioritized in the R&R Plan (Section 4). The most common LOF drivers of high risk rating were liquefaction susceptibility, pipe obstruction rating, and structural rating. On the other hand, the most common COF drivers of high risk rating were proximity to waterways, large pipe diameter, and proximity to high traffic flow areas. Appendix F provides the risk rating for all pipes in shapefile and excel format for the City GIS department’s use. See the “Risk column” located in the last few columns.

36 Section 4: Renewal and Replacement Plan
Based on desktop condition assessment and CCTV inspection results, sewer segments were analyzed for required system improvements and recommended CCTV surveys. The Renewal and Replacement Plan involves a discussion of methodology and costs, a review of the recent projects from the current CIP to ensure recommended improvements and inspections were aligned with the current efforts, a summary of the major deficiencies present in the Main and Venus Way Lift Stations, and a summary of project recommendations.

4.1 Rehabilitation Selection Methodology
For pipe segments without inspection data, risk and diameter was evaluated for CCTV prioritization. Pipe segments with a risk rating of medium of greater (three of five or greater) were recommended to be surveyed. In addition, large diameter pipes (24-inch diameter pipe or larger) of any risk rating were recommended to be surveyed. Figure 4-1 illustrates this risk and large diameter data consideration. While the initial plan was to CCTV high and extreme risk pipes outputted from the desktop risk analysis, further evaluation revealed that the budget allowed for medium risk pipelines to be included in the CCTV recommendations. Note that the CCTV prioritization map does not distinguish inspection data availability, and as such will differ from the rehabilitation recommendation map where pipe condition data (CCTV survey) allows for more fine-tuned rehabilitation recommendations.

Figure 4-1: CCTV Prioritization Data Map

Item # 16.

Sewer Utility Asset Renewal and Replacement Study
37 For pipe segments with survey data, a two-part process determined a pipe’s final rehabilitation recommendation. First, defect-level rehabilitation methods such as point repair, lining, or no action (blank) are selected for each defect in the “defect codes” module. Second, a decision tree was prepared that determines the pipe rehabilitation recommendation by analyzing the following:
• CCTV structural peak score and overall peak score
• Number of point repairs and lining recommendations (output) by the defect-level rehabilitation methods or “defect codes” module
• Number of defects
• Length of major (score of four or five) and/or minor defects (score of three) • Presence of specific defects such as ID (infiltration drippers) or SRCC (Reinforcement Corroded Chemical)

4.1.1 Defect Codes
Defect-level rehabilitation methods were selected and imported into the “Defect Codes” input window of the IAP program. Appendix H provides a full list of defect-level rehabilitation methods assigned for defects of all scores and all types. Table 4-1 presents a sample of the rehabilitation methods assigned for structural defects with a score of five.

38 4.1.2 Rehabilitation Decision Tree
Figure 4-2 illustrates the rehabilitation selection process. First, survey data availability is checked in the “[Has CCTV Data]” condition box. Pipes without survey data are then evaluated for risk and large diameter pipes. Pipes with survey data are then screened for inspection score. As the decision tree progresses, each pipe is analyzed for its number of point repairs and lining recommendations outputted by the “defect codes” module, number of defects, length of defects, and presence of specific minor but not negligible defects.

When multiple rehabilitation options are present, a cost comparison is done to determine the best action.

This is to ensure that a pipe would not be recommended to have 10 sectional liners when a full liner would be more cost efficient. In another example, when multiple point repair(s) by excavation or sectional liner(s) are present, the cost to replace or cost to perform a “full liner + point repair(s) by excavation” is compared to ensure the best action is recommended.

40 4.1.3 Analysis Quality Check
For each decision tree branch, spot checks were performed to see if the rehabilitation recommendations matched engineering expectations. For example, Figure 4-3 illustrates a pipe which was recommended to be replaced. Using the IAP program, defects present in the pipe and suggested rehab methods were reviewed and validated. At least 20 percent of each decision tree branch was reviewed for each rehabilitation type except pipes with “No Action” which have received a risk score of one (negligible) or two (low).

Figure 4-3: Example Analysis Quality Check in IAP

4.1.4 Staff Input
Prior to draft report submission, a preliminary rehabilitation decision tree was sent to the City in July 2020 in the event that preliminary staff input was desired. At the time, review was deferred until after draft report submission. Thus, recommendations are currently based on prior condition assessment projects and 938

41 engineering experience. Defect-level rehabilitation methods and decision tree can be adjusted to best suit City operational preferences.

4.2 Basis of Cost Assumptions
Detailed unit costs for the rehabilitation items used in the Class 5 cost estimate can be found in Appendix J.

The cost per foot is specified by pipe size. Unit costs are provided for the following:
• CCTV
• Pipe Replacement
• Point Repair(s) by Excavation
• Sectional Liner(s)
• Full Pipe Length Cured in Place Pipe (Full CIPP)
In general, material costs were provided by vendor quotations and labor costs were estimated using RSMeans construction cost database. For pipes with unknown diameters, the average pipe diameter of nine inches was used for costing. For pipes with unknown depths, the average pipe depth of 11 feet was assumed. The unit costs used to develop rehabilitation recommendations are budgetary construction costs and do not include engineering, permitting, legal, administrative, or other planning costs typical of budgetary capital improvement planning. City input for CIP planning level costs either in the form of percentage breakdown or recent bid tabulations would further calibrate the model to ensure the best recommendations are made.

4.3 Review of Recent Projects
As a part of this renewal and replacement study, a review of recent City projects was performed to ensure our recommendations are aligned with recent and planned projects.

4.5 Summary of Recommendations
Recommendations of system improvements and CCTV inspections total $17.4 million in construction costs.

Asset renewal and replacement priorities were assessed based on inspection data, desktop risk evaluation, and rehabilitation selection methodology described in previous sections. The results are presented below.

4.5.1 Sewer Main Pipelines
Of the approximately 105,000 LF (449 segments) of sewer inspected, about 50,000 LF (178 segments) require improvement. The construction cost of system improvements is estimated at approximately $17 million. Of the remaining 685,000 LF segments with no inspection data, it is recommended that 55,000 LF of medium to extreme risk pipes and/or large diameter pipes receive CCTV inspection, with an estimated cost totaling approximately $400,000. Recommendations of system improvements and CCTV inspections total $17.4 million in construction costs. Large diameter pipe is currently defined as 24-inch diameter and can be adjusted. Recommended improvements include:
• Additional CCTV
• Pipe Replacement
• Full Cured-In-Place Pipe (CIPP)
• Full CIPP + Point Repair(s) by Excavation
• Point Repair(s) by Excavation
• Sectional Liner(s)
• Sectional Liner(s) + Point Repair(s) by Excavation
Figure 4-4 provides the sewer main pipeline rehabilitation recommendations. The capital improvement program (CIP) recommendations for each asset is also included in GIS and tabular format in Appendix A.

Note that these recommendations are subject to change depending on future discussions with operational staff prefers to determine rehabilitation preferences of the various levels and types of defects. The Class 5 cost estimates are high level (1-2% planning level) and will be refined as project scopes are further defined.

Detailed cost estimates are recommended when further CIP budgeting and planning takes place. 941

47 4.5.3 Preliminary Capital Improvement Plan Alternatives Summary BC has developed three distinct Capital Improvement Plan (CIP) alternatives to phase out the necessary rehabilitation efforts. Alternative A presents CIP grouping based on risk grades. Alternative B focuses rehabilitation geographically within the sewer basin. Alternative C is a hybrid approach wherein pipes with risk and significant defects are prioritized in the first year and after which a geographic approach is applied for ease of construction. With the given data, Alternative C is recommended among the three alternatives explored here.

However, note that the CIP grouping presented in Alternatives A, B, and C serve as preliminary groupings of sewer pipe rehabilitations. The alternatives presented at this stage are not exhaustive of other possibilities and modifications. Within Appendix A, you will find a “Preliminary Rehab Recommendation.shp” shapefile and excel export results to help facilitate further development of the CIP. The shapefile attribute table contains column “CIP_Phase” which match up with the 4 phases in Alternative A and B. The table also includes column “CIP_ST” which allows sorting of pipes along the same street to facilitate the development of visuals or further analysis of risk and rehabilitation data for CIP development. 945

62 4.5.7 Sewer Lift Station Rehabilitation
The Main Lift Station and Venus Way Lift Station were inspected, and major deficiencies were catalogued (refer to Table 4-3). The variable frequency drives (VFDs), pump #3, and grinder are the main items requiring rehabilitation. The detailed score for each inventory item is provided in Appendix K, Main and Venus Way Lift Station Inspections Report. Per City’s 2019-24 CIP, project 6124, an allowance of $100,000 annual investment from FY 2019-20 through 2022-23 is planned to address these rehabilitation needs.

4.5.8 Estimated Construction Cost
The Association for the Advancement of Cost Engineering (AACE) Class 5 Estimate is a rough order-ofmagnitude estimate typically used to evaluate alternatives and is the class of estimate used in this report.

Standard unit prices were developed for the primary components in each proposed construction contract.

Scope items were parametrically estimated using cost data from similar projects in scope and size and adjusted to suit the specific requirements of this project. The estimated construction costs presented are considered conceptual and include a 45 percent contingency factor. Additionally, the presented costs are budgetary construction costs and do not include engineering, permitting, legal, administrative, or other planning costs typical of budgetary capital improvement planning. 960

CCTV Inspection Scope
November 14, 2019
Scope of Work
HydroScience Engineers (HSE) plans to contract with National Plant (Contractor) to inspect portions of the City of Milpitas’ large-diameter trunk sewers and other local collector sewers with highdefinition CCTV equipment. For large-diameter trunk sewers in the Trunk A grouping below, provide an option to collect 2D laser and sonar data in addition to CCTV. CCTV inspections shall be NASSCO PACP compliant. The actual length to be inspected and inspection methods will be determined later based on pricing, field production, and available budget. During contracting, HSE and Contractor will determine the inspection equipment specifications.

Each “Priority” group below contains groupings of reaches, also listed in order of priority. We expect the Contractor will be able to inspect all the Priority 1 reaches. For Priority 2 reaches, the Contractor should inspect the first grouping and then move onto the second grouping, starting with the largest diameters reaches and working towards the smaller diameters. Within the grouping, the inspection Contractor will be allowed to select the order in which to inspect the reaches based on ease of access, traffic control, and other factors; however, the inspected reaches shall be contiguous as much as possible.

See the attached figures and spreadsheet for the candidate list of reaches planned for inspection.

Also provided are shapefiles of the sewer pipes and manholes. The two fields in the sewer pipes attribute table, [CCTV_Plan] and [Diam_CCTV], contain the designated grouping and the expected pipe diameters, respectively. Lengths are based off of the [MEASUREDLE] field. Groupings below have the same names as the inspection maps, with GIS attribute label [CCTV_Plan] in parentheses.

PRIORITY 1
Trunk A_P1 (Trunk1)
Reinforced concrete pipe (RCP), diameters of 33, 36, 39, 42, 54, and 66 inches. 37 reaches, total length 8,830 linear feet (lf). Provide option to perform 2D laser and sonar inspection on a portion of the pipeline.

Trunk B_P1 (Trunk2)
RCP and vitrified clay pipe (VCP), diameters of 27 and 33 inches. 24 reaches, total length 5,760 lf.

Trunk C_P1 (Trunk3)
RCP and VCP, diameters of 24 and 30 inches. 15 reaches, total length 4,850 lf.

SW Area 21-24_P1 (Sub_21-24)
Mostly VCP, diameters of 21 and 24 inches. 19 reaches, total length 4,520 lf.

SW Area 10-18_P1 (Sub_10-18)
Mostly VCP, diameters of 10, 12 ,15, and 18 inches. 162 reaches, total length 46,720 lf.

SW Area 8_P1 (Sub_8)
Mostly VCP, 8-inch-diameter, 26 reaches, total length 8,660 lf. 965

CITY INSPECTIONS
To be inspected by City of Milpitas forces using City-owned equipment (WinCan). Mostly 6- and 8-inch-diameter VCP pipes. 389 reaches, total length 98,750 lf.

Manholes
There is no plan to perform MACP inspections on manholes; however, during CCTV inspection, the inspection Contractor shall capture video footage in each manhole to allow a basic assessment of manhole conditions.

Cleaning
Cleaning is not anticipated for sewers 15-inch-diameter and larger, and only targeted cleaning is anticipated for 8-inch- to 12-inch-diameter sewers. The Contractor shall attempt to inspect each sewer reach without cleaning. If unable to complete an inspection, mark the record “MSA” per NASSCO PACP, and alert the City immediately. Depending on availability, City forces may be dispatched to clean the pipe at that time, or may clean the pipe later for potential reinspection.

Sewer Utility Asset Renewal and Replacement Study
Appendix I
GIS Updates
GIS Data Received
A copy of the City GIS was provided in the Fall of 2019. There are 17,880 assets where 3240 are sewer pipes and 14,640 are laterals. On June 17, 2020, HSE provided GIS updates with revisions to drawing number, shape length, elevations, material, year, abandoned tag, diameter, private ownership tag, and added GIS segments.

GIS Updates
In the process of the desktop condition assessment task and renewal and replacement plan, two updated GIS shapefiles were created – risk GIS (Appendix F) and rehabilitation GIS (Appendix A). To both updates GIS shapefiles, the City GIS was updated based upon results of the CCTV and modeling efforts. It was then joined with CCTV inspection score data, rough pavement presence was determined, and depth was calculated by subtracting pipe inverts from known manhole rim elevations. Then, this was joined with risk updates (first shapefile) or rehabilitation updates (second shapefile).

Risk GIS
The first GIS shapefile involves the risk updates (desktop condition assessment). The attribute table provides the risk scores (normalized from 1-5, normalized from 1-100, and total mathematical score) as well as LOF COF scores and their constituents. Each LOF and COF factor has their own column where the number shown is the rating multiplied by the weighting described earlier in this report.

Rehabilitation GIS
The second GIS shapefile involves renewal and replacement fields. Important fields added to the City GIS in this version includes rehabilitation recommendation for each asset, number of rehabilitations (point repair(s), section liner(s), full lining), and flow chart branch (the decision tree path that led to the recommendation). The “total cost” column was the default name by InfoAsset and factors in traffic control and a 45% markup for sewer bypassing, mobilization/demobilization, and construction cost and market contingency.

However, the cost does not include planning costs such as engineering, permitting, legal, administrative, or other items as stated in summary tables throughout the report.

GIS Fixes
Some minor post rehabilitation analysis fixes had to be made. These edited pipes were exported as shapefiles and provided as attachments in this appendix - (duplicate pipes.zip and before rehabilitation adjustments.zip). The first issue involved duplicate GIS pipes. These were reviewed and removed. Facility IDs with more than 1 pipe were exported into the “Appx I_duplicate pipes.zip”. The second issue involved the choice of “Facility ID” as the unique identifier for CCTV surveys. Upon further review, this identifier is not unique for around 50 of the 3240 pipes with Facility ID. For around 50 pipes, 2 to 4 pipes had identical facility ID but spatially different GIS segments along the same path. As a result, a rehabilitation cost was attributed to the first of many pipes with the same facility ID and the other pipes of different lengths was then assigned the exact same rehabilitation, rehabilitation length, and associated cost. For example, the 2 pipe GIS segments with Facility ID “10160-10164” were each assigned a “Full CIPP” rehabilitation recommendation with a cost of $36,000 of each with the rehab length assumption of 393 feet. However, one of the GIS segments had a pipe length of 10 feet. This resulted in a vastly greater cost than it should have. In addition, the number of 1006
Item # 16.

Sewer Utility Asset Renewal and Replacement Study
rehabilitation items was attributed to each GIS segment. Other identifiers were searched in the attribute table, but ultimately because this identifier was used for the CCTV surveys, this is the identifier we had to stick with. Resolution: for these 50 pipes, BC edited this GIS version to fix the planning cost and properly assign the number of rehab and rehab length. These 50 pipes were exported into “Appx I_before_rehab_adjustments.zip”. In future GIS updates, City staff should consider generating a new and unique facility ID field.

1 Appendix J: Basis of Cost Assumptions
J.1 Basis of cost assumptions
This section describes the cost basis for rehabilitation items. Items related to quotes from manufacturers only include material and installation costs. These do not include labor or agency costs used for master planning such as administrative, permitting, or other costs. For pipes with unknown diameters, the average pipe diameter of nine inches was used for costing. For pipes with unknown depths, the average pipe depth of 11 feet was assumed.

J.1.1 CCTV Costs
Table J-1 presents CCTV costs used in the analysis.

1CCTV bids are from City of Bloomington FY 2017 CCTV Inspections PROJECT NO. # 50-18-53007-17-00. CITY BID NO. 2017-16. The costs shown here are an average of the bids from Michels Pipe Services, National Power Rodding Corp., and Bloomington City engineer estimate. G.A. Rich & Sons, Inc. was excluded due to low bids.

2 J.1.2 Pipe Replacement
Table J-2 and J-3 presents pipe replacement costs for pipes located under pavement and not under pavement, respectively. The cost shown on the tables below reflect pipe material, installation, backfill, and excavation costs. Since GIS data did not provide pavement information, the presence of pavement was determined by the “select by location” and intersecting pipes with the USGS transportation and road segments layer. Of 3254 pipes, 90% of the pipes (2937 pipes) were under pavement.

Table X-X and X-X presents point repair(s) by excavation costs used in the analysis. The costs presented are per point repair. A pipe assigned the rehabilitation recommendation “point repair(s)” or a combination of lining and “point repair(s)” may have more than one point repair. The excavation cost assumes 10 feet sections. The unit costs ($/LF) are taken from pipe replacement section and multiplied by 10. No additional multiplier was applied at the moment. This may result in a lower end of cost estimation. Typically, a point repair compared to a full pipe replacement will have a much greater unit cost due to similar equipment, machine rental, and labor costs.

Scope and Methodology
Introduction
City of Milpitas entered into an agreement with ADS Environmental Services to conduct flow monitoring at twenty-three (23) metering points in the City of Milpitas Collection System. The study was conducted over a ninety (90) day period. The study period is November 16, 2019 - March 09, 2020. The primary objective of the monitoring was to determine current flows for wet weather planning purposes.

Project Scope
The scope of this study involved using flow monitors to quantify wastewater flows at the designated locations.

Specifically, the study included the following key components. • Investigate the proposed flow-monitoring sites for adequate hydraulic conditions. • Flow monitor installations.
• Flow monitor confirmations and data collections.
• Flow data analysis.

Equipment installation was completed on November 15, 2019. The study period began on November 16, 2019 and was completed on March 09, 2020 .

Flow Monitoring Equipment
The ADS FlowShark Triton monitor was selected for this project. This flow monitor is an area velocity flow monitor that uses both the Continuity and Manning's equations to measure flow.

The ADS FlowShark Triton monitor consists of data acquisition sensors and a battery-powered microcomputer. The microcomputer includes a processor unit, data storage, and an on-board clock to control and synchronize the sensor recordings. The monitor was programmed to acquire and store depth of flow and velocity readings at 5-minute intervals.

The FS Triton monitor features cross-checking using multiple technologies in each sensor for continuous running of comparisons and tolerances. The FS Triton monitor can support two (2) sets of sensors. The sensor option used for this project was:

The Peak Combo Sensor installed at the bottom of the pipe includes three types of data acquisition technologies.

The up looking ultrasonic depth uses sound waves from two independent transceivers to measure the distance from the sensor upward toward the flow surface; applying the speed of sound in the water and the temperature measured by sensor to calculate depth.

The pressure depth is calculated by using a piezo-resistive crystal to determine the difference between hydrostatic and atmospheric pressure. The pressure sensor is temperature compensated and vented to the atmosphere through a 2 1299

desiccant filled breather tube.

To obtain peak velocity, the sensor sends an ultrasonic signal at an angle upward through the widest cross-section of the oncoming flow. The signal is reflected by suspended particles, air bubbles, or organic matter with a frequency shift proportional to the velocity of the reflecting objects. The reflected signal is received by the sensor and processed using digital spectrum analysis to determine the peak flow velocity.

Installation
Installation of flow monitoring equipment typically proceeds in four steps. First, the site is investigated for safety and to determine physical and hydraulic suitability for the flow monitoring equipment. Second, the equipment is physically installed at the selected location. Third, the monitor is tested to assure proper operation of the velocity and depth of flow sensors and verify that the monitor clock is operational and synchronized to the master computer clock. Fourth, the depth and velocity sensors are confirmed and line confirmations are performed.

In pipes up to 42 inches in diameter, the sensors were mounted on expandable stainless steel rings, inserted at least a foot upstream into influent pipes and tightened against the inside walls of the pipes. Influent pipe installations reduce the influences of turbulence and backwater often caused by changes in channel geometry in manholes. 3 1300

Data Collection, Confirmation, and Quality Assurance
Data collects were done remotely via wireless connect on a weekly basis via ADS Field Representatives. During the monitoring period, field crews visit each monitoring location to verify proper monitor operation and document field conditions. The following quality assurance steps are taken to assure the integrity of the collected data:

Measure power supplies: monitors were powered by dry cell battery packs. Voltages were recorded and battery packs replaced, as necessary. Separate batteries provided back-up power to memory allowing primary batteries to be replaced without loss of data.

Clock synchronization: Field crews synchronized monitor clocks to master clocks.

Confirm depth and velocity readings: Field crews descended into meter manholes to manually measure depths and velocities and compare them meter readings to confirm that they agreed. They also measured silt levels, if any, in the inverts of the pipes. Silt areas were subtracted from flow areas to compute true areas of flow.

Confirm average velocities through cross-sectional velocity profiles: Since ADS velocity sensors measure peak velocity, field crews collected cross-sectional velocity profiles in order to develop a relationship between peak and average velocity in lines that meet the hydraulic criteria.

Upload and Review Data: Data collected from the monitors were uploaded and reviewed by a Data Analyst for completeness, outliers and deviations in the flow patterns, which indicate system anomalies or equipment failure.

Flow Quantification Methods
There are two main equations used to measure open channel flow: the Continuity Equation and the Manning Equation. The Continuity Equation, which is considered the most accurate, can be used if both depth of flow and velocity are available. In cases where velocity measurements are not available or not practical to obtain, the Manning Equation can be used to estimate velocity from the depth data based on certain physical characteristics of the pipe (i.e. the slope and roughness of the pipe being measured). However, the Manning equation assumes uniform, steady flow hydraulic conditions with non-varying roughness, which are typically invalid assumptions in most sanitary sewers. The Continuity Equation was used exclusively for this study.

Continuity Equation
The Continuity Equation states that the flow quantity (Q) is equal to the wetted area (A) multiplied by the average velocity (V) of the flow.

Q = A * V
This equation is applicable in a variety of conditions including backwater, surcharge, and reverse flow.

Data Analysis and Presentation
Data Analysis
A flow monitor is typically programmed to collect data at either 15-minute or 5-minute intervals throughout the monitoring period. The monitor stores raw data consisting of (1) the ultrasonic depth, (2) the peak velocity and (3) the pressure depth. The data is imported into ADS's proprietary software and is examined by a data analyst to verify its integrity. The data analyst also reviews the daily field reports and site visit records to identify conditions that would affect the collected data.

Velocity profiles and the line confirmation data developed by the field personnel are reviewed by the data analyst to 4 1301

identify inconsistencies and verify data integrity. Velocity profiles are reviewed and an average to peak velocity ratio is calculated for the site. This ratio is used in converting the peak velocity measured by the sensor to the average velocity used in the Continuity equation. The data analyst selects which depth sensor entity will be used to calculate the final depth information. Silt levels present at each site visit are reviewed and representative silt levels established.

Occasionally the velocity sensor's performance may be compromised resulting in invalid readings sporadically during the monitoring period. This is generally caused by excessive debris (silt) blocking the sensor's crystals, shallow flows (~< 1") that may drop below the top of the sensor or very clear flows lacking the particles needed to measure rate. In order to use the Continuity equation to quantify the flow during these periods, a Data Analyst and/or Engineer will use the site's historical pipe curve (depth vs. velocity) data along with valid field confirmations to reconstitute and replace the false velocity recordings with expected velocity readings for a given historical depth along the curve.

Selections for the above parameters can be constant or can change during the monitoring period. While the data analysis process is described in a linear manner, it often requires an iterative approach to accurately complete.

Data Presentation
This type of flow monitoring project generates a large volume of data. To facilitate review of the data, results have been provided in graphical and tabular formats. The flow data is presented graphically in the form of scattergraphs and hydrographs. Hydrographs are based on 5-minute averaging. Tables are provided in daily average format. These tables show the flow rate for each day, along with the daily minimum and maximums, the times they were observed, the total daily flow, and total flow for the month (or monitoring period). The following explanation of terms may aid in interpretation of the tables and hydrographs.

MIL_0186
Pipe Dimensions 8
Silt Level 1.63"
Overview
Site MIL_0186 functioned under normal conditions during the period Saturday, November 16, 2019 to Monday, March 9, 2020 . This site exhibited an observable response to the wet weather events of November 26, 2019 - November 27, 2019 and December 7, 2019 - December 8, 2019. Surcharge conditions were experienced at this location. Review of the scattergraph shows free flow conditions during the study period.

Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted to date and support the relative accuracy of the flow monitor at this location. Data confidence is less than typical due to sediment. A data gap also occurs beginning February 02, 2020 through February 14, 2020 and another data gap on March 02, 2020 through March 05, 2020 resulting from a meter malfunction.

MIL_0649
Pipe Dimensions 21.5
Silt Level 0.00"
Overview
Site MIL_0649 functioned under normal conditions during the period Saturday, November 16, 2019 to Monday, March 9, 2020 . This site exhibited an observable response to the wet weather events of November 26, 2019 - November 27, 2019, December 7, 2019 - December 8, 2019, and January 16, 2020 - January 17, 2020. Review of the scattergraph shows that free flow conditions were recorded during the study period.

Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted to date and support the relative accuracy of the flow monitor at this location.

This location was installed upstream of site MIL_1790 and downstream of the combined flows of sites MIL_0386 and MIL_2840. A review of balancing with the combined flows of MIL_0386 and MIL_2840 into MIL_0649 and MIL_2491 shows a net flow between the sites of 0.426 MGD.

Overview
Site MIL_0715 functioned under normal conditions during the period Saturday, November 16, 2019 to Monday, March 9, 2020 . This site exhibited an observable response to the wet weather events of November 26, 2019 - November 27, 2019, December 7, 2019 - December 8, 2019, and January 16, 2020 - January 17, 2020. Review of the scattergraph shows that free flow conditions were recorded during the study period.

Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted to date and support the relative accuracy of the flow monitor at this location. Due to meter malfunction, data confidence is less than typical during January 27, 2020 through February 04, 2020. Also a data gap occured beginning January 05, 2020 through January 09, 2020.

Overview
Site MIL_0744 functioned under normal conditions during the period Saturday, November 16, 2019 to Monday, March 9, 2020 . This site exhibited an observable response to the wet weather events of November 26, 2019 - November 27, 2019, December 7, 2019 - December 8, 2019, and January 16, 2020 - January 17, 2020. Surcharged conditions were experienced at this location. Review of the scattergraph shows that both free flow and backwater conditions were recorded during the study period.

Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted to date and support the relative accuracy of the flow monitor at this location.

Silt Level 0.00"
Overview
Site MIL_1043 functioned under normal conditions during the period Saturday, November 16, 2019 to Monday, March 9, 2020 . This site exhibited a small response to the wet weather events of November 26, 2019 - November 27, 2019, December 7, 2019 - December 8, 2019, and January 16, 2020 - January 17, 2020. Review of the scattergraph shows that free flow conditions were recorded during the study period.

Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted to date and support the relative accuracy of the flow monitor at this location.

This location was installed downstream of MIL_1193. A review of balancing of combined flows MIL_1043 and MIL_2840 shows a net flow of 0.663 MGD.

Site Information
MIL_1193
Pipe Dimensions 21
Silt Level 0.00"
Overview
Site MIL_1193 functioned under normal conditions during the period Saturday, November 16, 2019 to Monday, March 9, 2020 . This site exhibited a small response to the wet weather events of November 26, 2019 - November 27, 2019, December 7, 2019 - December 8, 2019, and January 16, 2020 - January 17, 2020. Review of the scattergraph shows that free flow conditions were recorded during the study period.

Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted to date and support the relative accuracy of the flow monitor at this location. Due to a meter malfunction, data confidence is less than typical during December 16, 2019 through December 20, 2019. A data gap occurs during December 20, 2020 at 10:00 pm through December 27, 2020 at 6:00 am.

This location was installed upstream of sites MIL_1043 and MIL_2840. (See MIL_1043 and MIL_2840 Site Commentary for More Details)
Observations
Average flow depth, velocity, and quantity data observed during Saturday, November 16, 2019 to Monday, March 9, 2020 , along with observed minimum and maximum data, are provided in the following table.

MIL_1790
Pipe Dimensions 28
Silt Level 0.00"
Overview
Site MIL_1790 functioned under normal conditions during the period Saturday, November 16, 2019 to Monday, March 9, 2020 . This site exhibited an observable response to the wet weather events of November 26, 2019 - November 27, 2019, December 7, 2019 - December 8, 2019, and January 16, 2020 - January 17, 2020. Review of the scattergraph shows that free flow conditions were recorded during the study period.

Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted to date and support the relative accuracy of the flow monitor at this location.

This location was installed downstream of sites MIL_0190, MIL_0649 and MIL_1795. A check of balancing shows a net flow of 0.837 MGD between the sites.
