SUBJECT: Water Storage Reservoirs Condition and Risk Assessment

INTRODUCTION
The City of Fairfield (City) has retained West Yost to develop its 2023 Public Utility Master Plan (PUMP).

Task 5 for the PUMP describes a Water Storage Reservoirs Assessment (Assessment) to evaluate the condition of eight of the City’s reservoirs and to make recommendations for improvements. The following is a summary of the Task 5 Assessment scope of work:
• Prepare comprehensive, multi-discipline condition assessments of up to eight reservoirs. • Utilize the City’s existing risk framework to develop risk factors for each reservoir asset. • Develop recommendations for reservoir improvements to address deficiencies identified based on the condition assessment and/or results from the risk assessment.

The following eight reservoirs were selected for the Assessment: Cement Hill; Eastridge; Goldridge; Mangels; Martin Hill; Nelson Hill; Rancho Solano 3; and Rolling Hills. This technical memorandum (TM) summarizes the methods, findings, and recommendations that comprise the Assessment effort, and is organized into the following sections:
• Condition Assessment
• Risk Assessment
• Recommended Improvements

CONDITION ASSESSMENT
This section discusses the methodology used to assess the condition of the City’s reservoirs and summarizes the site investigation assessment results.

Methodology
Site investigations of eight reservoirs were conducted by the West Yost team on March 15 and March 16, 2023. The site investigations consisted of visual assessments of general site, mechanical, structural, and electrical assets at each reservoir. The evaluation included visual observations of all reservoir exteriors, and visual observations of four reservoir interiors: Eastridge, Mangels, Rancho Solano 3, and Nelson Hill. The site investigations were conducted by a team that included two City staff members from the Water Services Division, two West Yost project engineers, and three JDH Corrosion (JDH) specialists. The team also took photos and noted visible information (e.g., model number, serial number, size, etc.).

JDH provided corrosion condition assessments for each reservoir and ultrasonic thickness and coating thickness information for each metal reservoir. Ultrasonic thickness testing was used to determine the thickness of each steel reservoir shell and any wall thinning. Coating thickness testing was completed using the dry film thickness testing method. JDH also surveyed the cathodic protection (CP) system on three of five reservoirs that have such systems: Goldridge; Mangels; and Rolling Hills. At Martin Hill, JDH and City staff were unable to locate the rectifier or anode junction box to test the CP system. At Rancho Solano 3, JDH was unable to test the CP system as the reservoir was drained and water must be in the tank to test the CP system. Ground-penetrating radar (GPR) was used to locate rebar and confirm rebar spacing and depth in the concrete reservoirs. Detailed findings from JDH’s work are presented in Appendix A.

TJC and Associates (TJC) provided a preliminary structural assessment for each reservoir. They did not perform a visual inspection, but rather used pictures, record drawings, and information provided by JDH.

TJC conducted a structural assessment of the reservoirs to identify areas of seismic vulnerability and other structural deficiencies. TJC generated hydrodynamic sloshing loads for each reservoir, and calculated stability with respect to sloshing/freeboard, sliding, uplift, buckling and hoop stress. Detailed findings from TJC’s structural assessment are presented in Appendix B.

ATEEM met separately with City staff on March 30, 2023 to provide the electrical and instrumentation evaluations of each reservoir. This evaluation included observation of the incoming service, MCCs, PLCs, Control Panels, and other relevant equipment. Detailed findings from ATEEM’s electrical assessment are presented in Appendix C.

Based on the field observations, West Yost assigned a score to each component using the scoring index defined in Table 1. This information was used in the Risk Assessment presented later in this TM.

Table 1. Visual Condition and Performance Scoring Index Score Condition Score Index Performance Score Index
1 Excellent Component functioning as intended
2 Slight visible degradation In service, but elevated O&M costs 3 Visible degradation In service, but function is moderately impaired 4 Integrity of component moderately compromised In service, but function is highly impaired 5 Integrity of component severely compromised Component is not functioning as intended

It should be noted that requirements have changed since some of the reservoirs were constructed and as a result some of the inspected reservoirs are not in conformance with certain current code requirements or standards; however, such nonconformance does not necessarily warrant action. For example, certain reservoirs do not meet existing standards for footing height above existing ground elevation; however, such standards are based on concerns about flooding of the area around the reservoir, which in most cases is not a concern given the reservoir locations on hilltops or other areas not prone to flooding.

Moreover, bringing a substandard footing height into conformance with existing standards would require significant regrading of the site, with little or no commensurate benefit. Accordingly, this assessment takes into account the practicality and actual benefits of bringing existing reservoirs into conformance with applicable codes and standards, with a focus on the identification of improvements that are cost-effective and result in measurable benefits.

It should also be noted that several reservoirs do not meet current seismic standards, such as freeboard and anchorage; however, this nonconformance is due to changes in applicable codes since the reservoirs were constructed. Changes in operations can bring those reservoirs into compliance with current code requirements and are identified in this TM where applicable.

As of November 2018, safety cages are not considered OSHA compliant for fixed ladder fall protection.

The current OSHA standards requires either a personal fall arrest system or ladder safety system and are defined as follows:
• A Personal Fall Arrest System is a system that arrests a person’s fall from a ladder. The system consists of anchorage, a body harness, connector, and deceleration device or lifeline.

An example of this system is provided in Appendix D.
• A Ladder Safety System is a system designed to eliminate or reduce the possibility of falling from a ladder. A ladder safety system usually consists of a carrier, a lanyard, connectors, and a body harness. These systems include options for either a flexible cable or a rigid rail system. Examples are provided in Appendix D.

Per OHSA requirements, by November of 2036, all cages on a fixed ladder shall be replaced by either a personal fall arrest system or ladder safety system. Since compliance with this requirement is still several years out, it is recommended that the safety cages be removed, and an approved fall protection system be installed when other recommended improvements are implemented.

RISK ASSESSMENT
Critical asset condition and performance information collected during the reservoir site visits was used to perform a risk assessment of reservoir facilities. The risk assessment considers both likelihood of failure (LOF) ratings and consequence of failure (COF) ratings to quantify the risks associated with each asset and reservoir facility. Risk results were used to prioritize rehabilitation, replacement, or maintenance actions to meet established service reliability and performance goals.

The risk assessment methodology and results presented in this section are consistent with the results presented in the Condition Assessment section above and with the City’s 2023 Pump Station Asset Management Plan. These results are used as the basis for prioritization of capital improvements described in the Recommended Improvements section later in this TM. Capital improvement project costs and prioritization will be presented in Chapter 9 of the PUMP Report.

Key topics addressed in this section include:
• Risk Methods
• Asset Risk Results
• Reservoir Risk Results
The general approach used in the risk assessment is illustrated in Figure 1. The risk assessment involves development of LOF, COF, and risk scores for each individual asset, and each reservoir facility as a whole.

A rating for LOF is given to each individual asset and those ratings contribute to the overall LOF rating for each reservoir. In addition, a rating for COF is assigned to each reservoir, which is inherited by all individual assets at that reservoir. Asset risk is then calculated based on those asset LOF and asset COF scores.

Similarly, reservoir LOF and COF scores are combined to determine a comprehensive risk score and rating for each reservoir.

Figure 1. Reservoir Risk Assessment Methodology
Risk Methods
This section describes the methods used to perform the LOF and COF analyses and to determine the resulting risk level for each individual asset and each reservoir facility assessed for the PUMP.

Asset LOF
The asset LOF analysis considers the probability that a failure of a given asset will occur. The analysis includes two “failure modes”, specifically Physical Mortality and Level of Service. The factors considered in assessing each of these failure modes are presented in Table 4.

Table 4. Criteria Used for Asset LOF Evaluation
Failure Mode Criteria/Factor Description
Physical
Mortality Condition Rating
An asset with visible degradation is more likely to fail. While condition and age are often interdependent, newer components may be in poor condition due to environmental conditions or improper maintenance. Condition ratings are assigned to assets during the on-site condition assessment described previously.

Level of Service Performance Rating
An asset that does not perform as designed or intended is a level of service failure. Something does not have to physically happen to the asset for level of service failure to occur.

Asset performance may affect the level of service provided by the reservoir, depending on the role of that asset in day-to-day operations. Performance ratings were assigned to assets based on information obtained during the on-site condition assessment and West Yost’s understanding of the water system operations.

The LOF factors above are translated into numeric rankings of 1 to 5, with 5 indicating the highest LOF. An overall LOF score is determined by adding the two ratings, so each asset will have an overall LOF score of between 2 and 10. The factors and their range of potential ratings for each category are presented in Table 5.

Reservoir LOF
The LOF for each reservoir was evaluated by averaging the LOF scores of individual assets within each reservoir. Similar to the LOF scoring for assets, the reservoir LOF is rated on a 2 to 10 scale.

Asset and Reservoir COF
The COF analysis considers the impact that an asset or reservoir failure may have on the water system as a whole. As described previously, the COF was evaluated at the reservoir level, and all assets within that reservoir inherit the same COF score. This approach is based on the assumption that due to the relatively small number of assets at a reservoir, all assets are critical to reservoir operation. For each category, the criteria considered in determining the potential COF are presented in Table 6.

Table 6. Criteria Used for Reservoir COF Evaluation
Category Criteria/Factor Description
Operating Ability Type of Customers
in Zone
Water service disruptions impact the community while service is being restored. Critical customers (e.g., hospitals, industries, etc.) may have limited ability to handle prolonged water outages.

Service Reliability Ability to Meet Demand
Scenarios
Depending on the redundancy built into the system, certain zones may be able to meet service demands even with one reservoir offline. Some zones are constructed with no storage redundancy (i.e., Goldridge, Mangels, and Rancho Solano 3); for these reservoirs, there are additional consequences if the reservoir is taken offline for repairs or to be replaced. Since there is no another reservoir available to support the pressure zone, in the event that one of these reservoirs is removed from service, the sole source of supply to the pressure zone becomes the pump station(s) serving the zone. Therefore, in order to assess the severity of an outage for reservoirs in zones with no storage redundancy, the capacity of the pump station(s) serving each of these zones was evaluated for the ability of the pumps to compensate for a sudden lack of storage in the zone. Pump station(s) were reviewed to determine whether they could meet the greatest potential fire flow requirement in the zone, as well as the maximum day demand (MDD) for the zone. If the pump station(s) cannot meet one or both of these requirements on their own (i.e., fire flow and/or MDD), then it is more consequential if the reservoir that supports that pressure zone is taken offline.

The COF factors shown in Table 6 were translated into numeric rankings of 1 to 5, with 5 indicating the highest or worst consequence. Each reservoir is evaluated for the two factors, then are added together, with a resultant overall COF score between 2 and 10. This overall COF is assigned to all assets at that reservoir. The factors and their range of potential ratings for each category are presented in Table 7.

(a) Pump station capacity is assumed to be firm, meaning the largest pump is offline at each pump station. The capacity per pump at each pump station is based on the measured flow of each pump, as recorded in Table 2-2 of the City's Pump Station Asset Management Plan Update (West Yost, 2023).

Reservoir Risk Score Calculation
Upon determining all of the asset LOF and COF scores, a risk score is calculated for each reservoir using the following formula:

Reservoir Risk Score = Average of Asset LOF Scores x Reservoir COF Score Asset Risk Results
As noted above, the aggregated score for asset LOF and COF ranges from 2 to 10. By plotting the LOF and COF scores against each other, an overall risk level is assigned to each asset group. Risk levels are prioritized into five risk levels: Low, Medium-Low, Medium, Medium-High, and High, each of which is color-coded in Table 8. Table 8 shows the total number of assets that fall into each LOF and COF category.

These risk levels are assigned to the various cells using best engineering judgment to determine which combinations of score warrant the highest levels of concern versus those that warrant lesser levels of concern. Risk levels have been adjusted from those developed in the City’s 2023 Pump Station Asset Management Plan.

Table 10 presents the average asset LOF score, COF score, risk score, and risk level for each reservoir, ranked from highest to lowest risk. As indicated in Table 10, Eastridge is rated as a Medium-High risk reservoir, Rolling Hills and Martin Hill are rated as Medium-Low risk reservoirs, while the other five reservoirs are all rated as Medium risk. These results provide the basis for prioritizing the timing of the capital improvements described later in this TM. It should be noted that these results do not directly indicate a safety, health, or other risk to the City or its residents, rather, they should be used to assist the City in identifying facilities to be prioritized during capital improvement planning.

RECOMMENDED IMPROVEMENTS
Recommendations for improvements at each reservoir are listed in Table 11. Key items of note affecting multiple reservoirs include the following:

1. All sites require repairing of cracks/leaks and/or spot repair of corroded elements.

2. Five sites (Eastridge, Goldridge, Mangels, Rancho Solano 3, and Rolling Hills) require replacement of existing antiquated PLC equipment.

3. Four sites (Goldridge, Martin Hill, Rancho Solano 3, and Rolling Hills) require reinforcement of the reservoir to mitigate seismic overstressing.

4. Test CP system at Rancho Solano 3 when water is in the reservoir. Confirm location of rectifier or anode junction box to test CP system at Martin Hill and confirm it is working properly.

1. INTRODUCTION
The City of Fairfield is developing a Water Utility Master Plan and conducting a Rate Study Project. As part of plan development, TJC and Associates, Inc. (TJCAA) is providing structural evaluation of water system facilities. This report documents the results of TJCAA’s limited structural evaluation of storage reservoirs in the water system.

This evaluation included review of available documentation including a condition assessment report developed by JDH Consultants, Inc. (JDH) for this project. The following reservoirs are included in this assessment.

Concrete Reservoirs

1. Cement Hill Reservoir – 10 million gallon (MG) concrete tank (circa 1989)

2. Eastridge Reservoir – 16 MG concrete tank (circa 2003)

3. Nelson Hill Reservoir – 12 MG concrete tank (circa 1984) Welded Steel Reservoirs

1. Gold Ridge Reservoir – 2.2 MG welded steel tank (circa 2004)

2. Mangels Reservoir – 1.0 MG welded steel tank (circa 1990)

3. Martin Hill Reservoir – 2.7 MG welded steel tank (circa 2010)

4. Rancho Solano 3 Reservoir – 3.1 MG welded steel tank (circa 1988)

5. Rolling Hills Reservoir – 3.1 MG welded steel tank (circa 1989) TJCAA was retained by the City to provide a preliminary structural assessment of the tanks’ as-built conditions. TJCAA did not perform a visual inspection of the reservoirs, however, JDH performed a visual inspection and provided a report detailing an assessment of the existing condition of the reservoirs. In addition to a visual inspection, JDH also provided the following:

1. Ultrasonic Thickness Survey – estimated thicknesses of the various steel plates in the welded steel reservoirs.

2. Coating Thickness Testing – estimated thicknesses of the coating on various steel plates in the welded steel reservoirs.

3. Ground-Penetrating Radar – estimated depth and spacing for the rebar in the cast-in-place concrete reservoirs.

The JDH report can be found in Appendix A.

2. RESERVOIR DISCUSSION AND FINDINGS
TJCAA’s assessment of the reservoirs was limited to review of available engineering drawings for each reservoir and data provided by JDH in its condition assessment report (Appendix A).

Page 737 of 1105 ends

City of Fairfield Condition Assessment
July 2023 Page 4

2.1 Concrete Reservoirs

2.1.1 Cement Hill Reservoir
The Cement Hill Tank is a buried concrete reservoir constructed in 1989. The reservoir is rectangular in shape and has approximately 2 feet of soil on the top slab. The water height is 24 feet and the outside dimensions are approximately 316 x 199 feet. The capacity of the reservoir is approximately 10 MG.

Photos of the reservoir appear to show that it is in relatively good condition. No significant structural issues were reported by JDH. JDH was not, however, able to access the interior of the reservoir and therefore was only able to take photographs of the interior from the roof access hatch.

Based on review of the record drawings, the reservoir appears to have been constructed in a manner consistent with other reservoirs in the late 1980s. No significant structural issues were identified through TJCAA’s review of the as-built drawings. However, due to significant increases in design seismic ground motion values over the past 30 years, TJCAA recommends a full engineering evaluation of the reservoir components.

2.1.2 Eastridge Reservoir
Eastridge Reservoir is a buried concrete reservoir constructed in 2003. The reservoir is rectangular in shape and has approximately 2 feet of soil on the top slab. The water height is 24 feet and the outside dimensions are approximately 316 x 316 feet. The capacity of the reservoir is approximately 16 MG.

Photos of the reservoir appear to show that it is in relatively good condition. No significant structural issues were reported by JDH. JDH did, however, identify some leakage that has occurred through the walls from one cell to another, and one area of copper corrosion staining. Both items can cause corrosion in the reinforcing steel and therefore should be rectified as soon as possible.

Based on review of the record drawings, the reservoir appears to have been constructed in a manner consistent with other reservoirs in the early 2000s. No significant structural issues were identified through TJCAA’s review of the as-built drawings.

One item that came up during the review of JDH’s data is the concrete cover of the rebar. TJCAA noticed that cover over the various reinforcing bars ranges from ⅝ inch to 4⅞ inches for the primary reinforcing. Typical concrete cover for these types of structures is specified as 2 inches. Reduced cover can reduce the protection to the reinforcing steel. Increased cover can reduce the “d” distance (distance between the compression face and the tension reinforcing) within the wall and therefore reduce the wall’s capacity to carry the design loads.

TJCAA recommends performing a more extensive reinforcing study to determine the limits of reinforcing that is not in the proper location. In addition, the actual wall thickness should be determined to calculate the as-built “d” distance. In addition to further field investigation, due to increases in design seismic ground motion values over the past 20 years, TJCAA recommends a full engineering evaluation of the reservoir components.

2.1.3 Nelson Hill Reservoir
Nelson Hill Reservoir is a buried concrete reservoir constructed in 1984. The reservoir is rectangular in shape and does not have soil on the top slab. The water height is approximately 24 feet and the outside dimensions are approximately 357 x 316 feet.

The capacity of the reservoir is approximately 12 MG.

Photos of the reservoir appear to show that it is in relatively good condition. No significant structural issues were reported by JDH. JDH did, however, identify some leakage that has occurred through the walls from one cell to another. This leakage can corrode the reinforcing steel and therefore should be rectified as soon as possible.

Based on review of the record drawings, the reservoir appears to have been constructed in a manner consistent with other reservoirs in the early 1980s. No significant structural issues were identified through TJCAA’s review of the as-built drawings.

Concrete cover over the primary reinforcing ranged from 1¼ to 2⅝ inches. While these values are less critical than the cover found in the Eastridge Reservoir, the 1¼-inch cover should be further investigated to determine whether this is an anomaly, or a significant portion of the reinforcing has suboptimal cover. In addition to further field investigation, due to significant increases in design seismic ground motion values over the past 40 years, TJCAA recommends a full engineering evaluation of the reservoir components.

2.2 Welded Steel Reservoirs

2.2.1 Gold Ridge Reservoir
Gold Ridge Reservoir is a 2.2 MG welded steel reservoir constructed in 2004. The reservoir has a 122-foot diameter and a water height of 26.5 feet. Hold-down chairs are provided around the perimeter of the reservoir.

Photos of the reservoir show that it appears to be in relatively good condition. No significant structural issues were reported by JDH. JDH did, however, identify some areas of corrosion that should be spot-repaired. In addition, JDH identified loss of grout below the chime plate. This should be rectified as soon as possible.

TJCAA performed engineering calculations in accordance with AWWA D100-21 to determine maximum anticipated slosh height, anticipated potential for sliding, anticipated potential for uplift, maximum compression buckling stress, and maximum hoop stress. For the design seismic event, TJCAA’s findings are as follows:
• Slosh Height – 5.6 feet – Insufficient freeboard has been provided. • Available Freeboard – 4 feet.
• Sliding – Failure due to sliding is not anticipated.
• Uplift – Failure due to uplift is not anticipated.
• Buckling – Failure due to compression buckling is not anticipated. • Hoop Stress – The bottom two rings of the reservoir would be overstressed when subjected to the design seismic event. Reinforcement will be required to correct this condition.

Insufficient freeboard may be mitigated by lowering the operating level of the reservoir by approximately 2 feet.

2.2.2 Mangels Tank
Mangels Reservoir is a 1.0 MG welded steel reservoir constructed in 1990. The reservoir has a 103-foot diameter and a water height of 16 feet. Hold-down chairs are not provided around the perimeter of the reservoir.

Photos of the reservoir appear to show that it is in relatively good condition. No significant structural issues were reported by JDH. JDH did, however, identify some areas of corrosion that should be spot-repaired. In addition, JDH identified loss of grout below the chime plate. This should be rectified as soon as possible.

TJCAA performed engineering calculations in accordance with AWWA D100-21 to determine maximum anticipated slosh height, anticipated potential for sliding, anticipated potential for uplift, maximum compression buckling stress, and maximum hoop stress. For the design seismic event, TJCAA’s findings are as follows:
• Slosh Height – 5.0 feet – Insufficient freeboard has been provided. • Available Freeboard – 3 feet.
• Sliding – Failure due to sliding is not anticipated.
• Uplift – Failure due to uplift is not anticipated.
• Buckling – Failure due to compression buckling is not anticipated. • Hoop Stress – Failure due to hoop tensile stress is not anticipated.

Insufficient freeboard may be mitigated by lowering the operating level of the reservoir by approximately 2.5 feet.

2.2.3 Martin Hill Reservoir
Martin Hill Reservoir is a 2.7 MG welded steel reservoir constructed in 2010. The reservoir has a 135-foot diameter and a water height of 25 feet. Hold-down chairs are not provided around the perimeter of the reservoir.

TJCAA performed engineering calculations in accordance with AWWA D100-21 to determine maximum anticipated slosh height, anticipated potential for sliding, anticipated potential for uplift, maximum compression buckling stress, and maximum hoop stress. For the design seismic event, TJCAA’s findings are as follows:
• Slosh Height – 5.7 feet – Insufficient freeboard has been provided. • Available Freeboard – 3.2 feet.
• Sliding – Failure due to sliding is not anticipated.
• Uplift – Failure due to uplift is not anticipated.
• Buckling – Failure due to compression buckling is not anticipated. • Hoop Stress – The bottom two rings of the reservoir would be overstressed when subjected to the design seismic event. Reinforcement will be required to correct this condition.

Insufficient freeboard may be mitigated by lowering the operating level of the reservoir by approximately 2.75 feet.

2.2.4 Rancho Solano 3 Reservoir
The Rancho Solano 3 Reservoir is a 3.0 MG welded steel reservoir constructed in 1988.

The reservoir has a 143-foot diameter and a water height of 25 feet. Hold-down chairs are not provided around the perimeter of the reservoir. The reservoir was retrofitted in 2008 with two “girdle” bands to improve the ability to resist hoop stresses.

TJCAA performed engineering calculations in accordance with AWWA D100-21 to determine maximum anticipated slosh height, anticipated potential for sliding, anticipated potential for uplift, maximum compression buckling stress, and maximum hoop stress. For the design seismic event, TJCAA’s findings are as follows:
• Slosh Height – 5.9 feet – Insufficient freeboard has been provided. • Available Freeboard – 3.4 feet.
• Sliding – Failure due to sliding is not anticipated.
• Uplift – Failure due to uplift is not anticipated.
• Buckling – Failure due to compression buckling is not anticipated. • Hoop Stress – All the shell rings of the reservoir would be overstressed when subjected to the design seismic event. Reinforcement (in addition to that already provided) will be required to correct this condition.

Insufficient freeboard may be mitigated by lowering the operating level of the reservoir by approximately 2.75 feet.

2.3 Rolling Hills Reservoir
Rolling Hills Reservoir is a 3.1 MG welded steel reservoir constructed in 1989. The reservoir has a 143-foot diameter and a water height of 25 feet. Hold-down chairs are not provided around the perimeter of the reservoir. The reservoir was retrofitted in 2009 with two “girdle” bands to improve the ability to resist hoop stresses.

TJCAA performed engineering calculations in accordance with AWWA D100-21 to determine maximum anticipated slosh height, anticipated potential for sliding, anticipated potential for uplift, maximum compression buckling stress, and maximum hoop stress. For the design seismic event, TJCAA’s findings are as follows:
• Slosh Height – 5.4 feet – Insufficient freeboard has been provided. • Available Freeboard – 2.7 feet.
• Sliding – Failure due to sliding is not anticipated.
• Uplift – Failure due to uplift is not anticipated.
• Buckling – Failure due to compression buckling is not anticipated. • Hoop Stress – All the shell rings of the reservoir would be overstressed when subjected to the design seismic event. Reinforcement (in addition to that already provided) will be required to correct this condition.

Insufficient freeboard may be mitigated by lowering the operating level of the reservoir by approximately 3 feet.

3. LIMITATIONS
TJCAA did not receive geotechnical information for each specific site. TJCAA has assumed adequate soil for supporting the reservoirs and no significant issues related to soil that would require special foundations, such as pier-supported foundations.

TJCAA’s evaluation has been based on information provided in as-built drawings along with the JDH report. TJCAA has not ventured to assess the accuracy of the information provided. Therefore, any inaccurate information may have been used to develop the findings and recommendations within this document.

4. SUMMARY OF FINDINGS

4.1 Concrete Reservoirs
The concrete reservoirs were found to be in generally good condition; however, JDH reported leaking cracks between the various cells, corrosion of concrete, and inadequate cover for the rebar. TJCAA recommends the following:

1. Repair all cracks that are leaking within the reservoirs. This can be done with epoxy injection to seal the cracks.

2. Repair and restore any corrosion that is found within the concrete.

3. Conduct a more extensive evaluation of the concrete cover to determine whether the inadequate values are isolated cases or occur throughout the reservoirs. If the locations of the inadequate cover are structurally significant, TJCAA recommends the following:
• Coating the surface to provide additional protection for the rebar. • Building up additional concrete to provide additional protection for the rebar.

Where too much cover is provided, TJCAA recommends the following:
• Engineering analysis to determine whether the resulting structural section is adequate to resist the anticipated internal forces.

4.2 Welded Steel Reservoirs
JDH identified corrosion that should be spot-repaired as soon as possible along with replacement of grout under the chime of the reservoir. JDH also recommended periodic coating and inspections of the reservoirs to keep them from deteriorating further.

TJCAA’s evaluation found that all five of the welded steel reservoirs lacked sufficient freeboard. Limited freeboard will result in water impinging on the roof plates and support beams, which may result in roof damage. In an extreme event, roof plates can tear away at the roof/shell juncture or collapse. Although damage to the tank is possible, total collapse and loss of content because of inadequate freeboard is unlikely, in part, due to the time it takes for the wave to fully load/unload the structural elements.

Page 742 of 1105 ends

City of Fairfield Condition Assessment
July 2023 Page 9
One simple solution to the lack of freeboard would be to lower the operating height of the water level to allow for adequate freeboard. If this approach is not acceptable from an operations standpoint, another alternative is to raise the roof of the reservoirs by a few feet to create adequate freeboard.

Notes:

Fairfield Reservoir Condition Assessment
Utility Service Panels PLC Radio Lighting Level Transmitter Flowmeter Martin Hill Micrologix 1400 PLC has recently been discontinued. Components are still available and it should be possible to continue maintaining the PLC; however, it will eventually need to be replaced.

At Rancho Solano 3, the power meter pedestal was not found; unclear how power is getting to the site.

At Nelson Hill, the Industrial Gateway communications router is not operating consistently; staff is investigating.

At Rolling Hills, water is coming out of the pedestal conduit and flowing onto the ground. Algae is growing on the wet surfaces. This situation should be corrected as soon as possible. 1 = New and/or Works As Expected; 5 = Immediately Replace/Does Not Work Allen-Bradley Model 5/20 PLCs (at Eastridge, Gold Ridge, Mangels, Rancho Solano 3, and Rolling Hills) should be replaced immediately. They are past their useful life and replacements parts are only available via third party vendors.

A number of sites have outdoor receptacles that have missing covers.

Eastridge site is subfed from a local pump station. PLC communicates via blue hose cable to the pump station PLC. Any change to either PLC will require replacement of the blue hose with more modern technology.

The Goldridge level transmitter is located within PLC control panel. Because the level transmitter is connected to a pressure tap, there is effectively a water line into the panel. The level transmitter should therefore be relocated. In addition, the electrical panels are subject to direct sunlight and steps should be taken either to shade the panels or otherwise protect them from sun exposure.

Mangels has old washdown pump starter panel in larger overall panel. The pump no longer is in service. 1 - Immediate Replace

SUBJECT: Water Distribution System Condition and Risk Assessment

INTRODUCTION
The City of Fairfield (City) has retained West Yost to develop its 2023 Public Utility Master Plan (PUMP).

Task 6 for the PUMP describes a Water Distribution System Assessment (Assessment) to evaluate the condition of the City’s existing water distribution system and to make recommendations for improvements. The following is a summary of the Task 6 Assessment scope of services:
• Perform a desktop condition assessment of the water distribution system, including pipeline, valve, and service lateral assets.
• Develop an asset registry for the water distribution system, review background information, and perform workshops with City staff.
• Utilize the City’s existing risk framework to develop risk factors for each water distribution system asset type and assess risk for each asset.
• Based on the desktop condition and risk assessment results, develop a rehabilitation and replacement plan for pipelines, valves, and service laterals that can be incorporated into the Near-Term (2030) and Long-Term (2050) CIP.

This technical memorandum (TM) summarizes the methods, findings, and recommendations that comprise the Assessment effort, and is organized into the following sections:
• Asset Registry
• Condition Assessment
• Risk Assessment
• Rehabilitation and Replacement Plan

ASSET REGISTRY
In order to perform the condition and risk assessments, a comprehensive listing of the City’s water distribution system assets was required. The City provided GIS databases which included asset information such as location, size, type, material, and installation year. This information was used as the basis for the assessment.

Assets included in the assessment were:
 Pipelines ranging from 4-inches to 48-inches in diameter.  Valves greater than or equal to 24-inches in diameter, including both transmission main valves and facility valves. Facility valves are defined as valves associated with a pump station or reservoir facility and were identified by their location in the system and (e.g., valves that were not immediately adjacent to a transmission pipelines). Transmission valves are defined as valves attached to a distribution system pipeline greater than or equal to 24-inches and were identified by their adjacency to those pipelines.
 Service laterals greater than or equal to 3-inches in diameter (the City did not have location data for service laterals smaller than 3-inches in diameter) Table 1 presents a summary of the assets included in the final water distribution system asset registry.

Table 1. Water Distribution System Asset Registry – Count of Asset Types Asset Type Count
Pipelines 8,733 segments (391 miles)
Transmission Valves (≥24”) 300
Facility Valves (≥24”) 53
Service Laterals (≥3”) 3,746
Total 12,832

CONDITION ASSESSMENT
The desktop condition assessment was performed by using year of installation data provided by the City and an estimated useful life (EUL) to determine a remaining useful life (RUL) for each asset.

Asset EUL is the time that an asset provides valued service, after which it does not meet its intended service level. End of life is not necessarily indicative of catastrophic failure, and in most cases an asset can still hold functionality (but with a reduced level of service and/or reliability). Asset RUL can be estimated by comparing the actual age of assets (determined from installation date) to a standard useful life expectancy. In the absence of detailed condition or performance data, this approach provides an initial determination of assumed condition and can be used to project estimated renewal needs.

Standard useful life expectancies are documented by the American Water Works Association, Water Environment Research Foundation, in addition to other industry associations. EUL expectancies were developed for the distribution system assets using these industry standards and input from City staff. Each asset type within the water distribution system was assigned an estimated useful life, as presented in Table 2.

RUL was calculated for each asset by subtracting the asset age (how long the asset has been installed) from its estimated useful life (EUL) – see Equation 1. Asset age was calculated based on the installation date and current year as 2023. For example, an asset with a 50-year estimated useful life that has been in service 35 years would have a RUL of 15 years. RUL can also be expressed in terms of percent RUL, that is, the percent of useful life that remains for the – see Equation 2.

Eqn. 1: RUL = EUL – age
Eqn. 2: Percent RUL = RUL / EUL
Desktop Assessment Analysis
Asset RUL results were grouped into four classes for data visualization purposes. Classes range from Class A, which includes newer assets in the first 25 percent of their useful life expectancy/assets that are expected to be in new or like new condition, to Class D, which includes assets in the last 25 percent of their useful life expectancy/assets that are expected to be in poorer condition. Table 3 presents the percent RUL categories, associated classification, and expected condition rating.

Note that this desktop analysis uses age and estimated useful life values to estimate an expected condition. In the absence of condition or performance data, this approach provides an initial determination of assumed condition but does not provide a conclusive picture of actual asset condition.

For pipe and valve assets, end of useful life is not necessarily indicative of catastrophic failure, and in most cases an asset can still hold functionality (potentially with a reduced level of service) when it has reached the end of its useful life.

Figures 1 through 3 present a graphical representation of RUL class for each asset type. This information provides a snapshot view of the condition of the City’s water distribution system assets and where future R&R may be required. In general, the City’s pipelines and service laterals are generally in good to fair condition based on the RUL estimation and classification. The City’s transmission and facility valves are mostly in poor condition due to their older age and relatively short useful life of valves (for transmission valves, a maximum 33-year EUL, based on pipeline EUL; and for facility valves, a 20-year EUL).

RISK ASSESSMENT
The risk assessment considers both likelihood of failure (LOF) ratings and consequence of failure (COF) ratings to quantify the risk associated with each asset. The risk assessment methodology and results presented in this section are consistent with the results presented in the Condition Assessment section above and with the City’s 2023 Pump Station Asset Management Plan. These results are used as the basis for prioritization of the Rehabilitation and Replacement Plan, described later in this TM. Rehabilitation and replacement project costs will be presented in Chapter 9 of the PUMP Report.

Key topics addressed in this section include:
 Risk Methods
 Pipeline Risk Results
 Service Lateral and Valve Risk Results
The general approach used in the risk assessment is illustrated in Figure 4 (pipelines) and Figure 5 (service laterals and valves).

For pipelines, ratings for LOF and COF are assigned for each individual pipeline. Pipeline risk is then calculated based on those asset LOF and COF scores. For valves and service laterals, a rating for LOF is assigned for each individual asset. The COF for valves and service laterals is inherited from the adjacent or connecting pipeline based on the assumption that the pipeline appurtenances have a similar consequence of failure as its associated pipeline. Valve or service lateral risk is then calculated based on the asset LOF score and adjacent/associated pipeline COF score.

Risk Methods
This section describes the methods used to perform the LOF and COF analyses and to determine the resulting risk level for individual pipeline, service lateral, and valve assets assessed for the PUMP.

Pipeline LOF
The asset LOF analysis considers the probability that a failure of a given asset will occur. The analysis considers LOF as two factors, Percent of Remaining Useful Life (Eq. 2 in the Condition Assessment section) and Percent Likelihood of Failure from the City’s Fracta model. Where percent RUL could not be calculated due to lack of data, only LoF from the Fracta model was used. Table 4 describes what each LOF factor takes into consideration.

Table 4. Criteria Used for Asset LOF Evaluation
Criteria/Factor Description
Percent of Remaining
Useful Life
This factor takes into account the fact that older assets are more likely to fail than newer ones due to the age of materials and wear from repeated use. The percent of remaining useful life was determined by comparing installation date to the industry standard useful life for each asset, as discussed in the Condition Assessment section of this TM. Percent RUL = (EUL-age)/EUL.

Percent Likelihood of
Failure (Fracta)
The City had previously undertaken a likelihood of failure analysis with Fracta, Inc., which uses machine learning to develop a condition and risk rating of drinking water distribution pipelines.

Fracta assigns a Likelihood of Failure (LoF) condition assessment score to every pipe segment based on various risk factors and break history using both City of Fairfield data as well as data available for pipelines with similar environment criteria across the world. After gathering the historical pipe break data, relevant environmental variables are factored into the algorithm such as soil, elevation, proximity to water, railroads and more.

Fracta’s Likelihood of Failure (LoF) is the condition assessment score given to each pipeline asset in the water distribution system. It can be interpreted as the percent chance of failure for a pipe. The LoF percentage is the LoF for the next 12 months.

The LOF factors above are translated into numeric rankings of 1 to 10, with 10 indicating the highest LOF.

The Percent of Remaining Useful Life factor governed for 96 percent of the pipelines – this is due to the very low probability of failure within the next 12 months predicted through the Fracta model.

An overall LOF score is determined by taking the maximum value of the two ratings, so each asset will have an overall LOF score of between 1 and 10. The factors and their range of potential ratings for each category are presented in Table 5.

Service Lateral and Valve LOF
Fracta data was not available for service laterals and valves, so the LOF for these assets was evaluated solely based on percent of remaining useful life.

Asset COF
The COF analysis considers the impact that an asset failure may have on the water system as a whole, the City, and the surrounding community. As described previously, the COF was evaluated for the pipelines; then all service laterals and valves connecting or adjacent to that pipeline inherit that same COF score.

This approach assumes that the pipeline appurtenances have a similar consequence of failure as its associated pipeline. The criteria considered in determining the COF are presented in Table 6.

Table 6. Criteria Used for Asset COF Evaluation
Category Criteria/Factor Description
Operating
Ability Ability to Maintain Service
Operating ability considers the effect on the water system and the customers if the pipeline fails. Failure will have a varying degree of impact on the ability of the system to deliver water depending on the size and location of the asset.

Larger pipelines or pipelines with existing capacity deficiencies indicate a larger potential consequence.

Difficulty to
Repair
Street Type / Difficult
Area Identified by City
The time and/or resources required to repair or replace an asset depend on the location and accessibility of the asset. An easy repair or replacement is defined as being located on a local street with little vehicle and foot traffic and little disruption to the public. A difficult repair or replacement would be located on a highway, on-ramp, railway crossing, or area otherwise identified as challenging by the City.

The COF factors shown in Table 6 were translated into numeric rankings of 1 to 5, with 5 indicating the highest or worst consequence. Each pipeline was evaluated for the two factors, then added together, with a resultant overall COF score between 2 and 10 using the following formula:

Overall COF = Operating Ability (COF1) + Difficulty to Repair (COF2) This pipeline COF is assigned to all service laterals and valves adjacent to that pipeline. The factors and their range of potential ratings for each category are presented in Table 7.

Risk Score Calculation
Upon determining all the asset LOF and COF scores, a risk score is calculated for each pipeline, service lateral, and valve using the following formula:

Risk Score = Asset LOF Score x Asset COF Score
Risk Results
By plotting the LOF and COF scores of each asset against each other, an overall risk level was assigned to each asset. Risk levels are prioritized into five risk levels: Low, Medium-Low, Medium, Medium-High, and High, each of which is color-coded in Table 8. These risk levels are assigned to the various cells using best engineering judgment to determine which combinations of scores warrant the highest levels of concern versus those that warrant lesser levels of concern. This risk matrix is in alignment with the matrix developed in the City’s 2023 Pump Station Asset Management Plan and was also used for other asset type assessments within the PUMP.

REHABILITATION AND REPLACEMENT (R&R) PLAN DEVELOPMENT
A rehabilitation and replacement (R&R) plan was developed based on the condition and risk assessment results presented above. The condition assessment results were used to identify assets that are likely in poor condition and may be in need of rehabilitation or replacement. The risk assessment results were used to prioritize these assets within the framework of the Near-Term and Long-Term planning timeframes.

Each of the asset types, and how they were incorporated into the R&R plan, is discussed below.

Pipelines
 The oldest pipelines have a RUL of 19 years (i.e., are not expected to require replacement for 19 years, in year 2042)
 No pipelines were assessed to be High risk. 5.9 miles (51 segments) of pipeline were assessed to be Medium-High Risk (1.5% of total pipeline length) Service Laterals (≥3-inch)
 The oldest service laterals have a RUL of 19 years (i.e., are not expected to require replacement for 19 years, in year 2042)
 No service laterals were assessed to be High risk. Thirteen service laterals were assessed to be Medium-High Risk
The City’s pipelines and ≥3-inch service laterals are relatively new and hold a relatively low risk, with the lowest RUL at 19 years. For these reasons, replacements for pipelines and ≥3-inch service laterals are not recommended within the Near-Term (2030) timeframe. Starting in 2042, through the end of the Long-Term timeframe (2050), 20.1 miles of replacement are expected due to assets reaching end of EUL.

These 2042-2050 replacements should be prioritized by risk. in general, service laterals should be replaced when their adjacent pipeline is replaced.

The City provided anecdotal information that the service laterals (of all sizes) in certain “Priority Areas” of the City should be prioritized for replacement. Because service lateral information was not available spatially, meters were used to estimate the number of service laterals (all sizes) within the Priority Areas.

These service lateral replacements were distributed within the Near-Term timeframe (over 6 years, from 2025 to 2030). Note that only service laterals ≥3-inch were included in the condition and risk assessment sections of this TM, but the R&R will include recommendations for all size service laterals. The extents of the four Priority Areas were provided by the City and shown in Figure 7.

The City has been proactively replacing small diameter pipelines (≤6-inch) throughout their system in areas where these pipelines present capacity issues (e.g., courts with no hydrants). Based on the City’s current GIS, there are 9,075 feet of 4-inch pipeline and 135,528 feet of 6-inch pipeline remaining in the system. The City expects there is actually less than 1,000 feet of remaining 4-inch pipeline and acknowledged that the GIS is out of date. As of March 2024, the City was still in the process of updating their GIS to reflect pipeline upgrades. It was agreed that small diameter pipelines would only be recommended for replacement if they present a hydraulic deficiency. The City will continue to update their GIS to reflect recent upgrades and for consistency with the hydraulic model.

Valves
 252 valves have a RUL of less than or equal to 0 (in year 2025)  113 valves were assessed to be High risk. 157 valves were assessed to be Medium-High Risk The City’s valves are relatively old and higher risk due to primarily to the relatively short useful life of valves (20 to 33 years). Most valves have not been replaced since their adjacent pipeline was installed.

The City repairs or replaces valves reactively but has expressed interest in developing a system-wide valve replacement program. It is recommended all valves with zero RUL (252 valves) are included in replacement budgets within the next 5 years. These 252 valves were prioritized based on input from the City and the risk results. A list of priority valves was provided March 2024 by the City and were selected based on: major crossings (freeways); influent/effluent pump stations; effluent transmission mains from treatment plant; creek/canal crossings; source water flexibility and redundancy; single feed lines. These valve replacements can also be grouped by proximity for construction efficiencies.

Other valves that reach the end of their EUL in the planning timeframes should be budgeted for in the year they reach zero RUL.

Recommended R&R Plan
The R&R plan presented below is a forecast of expected improvements based on the age and expected condition of assets. The exact intervention (i.e., rehabilitation or replacement) and timing should be confirmed through condition assessment studies and/or validation with field and maintenance records.

Until the R&R plan is validated, the forecast should primarily be used for system-wide planning and budgeting (e.g., to estimate dollars per year budgeted for water system R&R). The R&R plan should be reviewed and updated annually, or as new condition or performance data becomes available; this approach should provide the City adequate funding for R&R throughout the Long-Term planning timeframe.

A summary of the proposed R&R plan is presented in Table 12 and Figure 7. Asset listings for each year of the plan are provided in Appendices A-1 (valves) and A-2 (pipelines and service laterals).
