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.

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).
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.

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.
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.

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.

N-C-268-60-22-20-WP-TM5
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).

Potable Water Pump Station – AMP Update
November 2023
1.0 INTRODUCTION
1.1 Background
In 2015, the City of Fairfield (City) undertook a condition and risk assessment of the City’s 16 potable water pump stations and two raw water pump stations. Results from the assessments were used to determine the functionality of the facilities and estimate the remaining useful life of the components. A risk-based system was developed to prioritize the most urgent improvements and define triggers that indicate when a pump station is ready for a maintenance or improvement action. The resulting Asset Management Plan (AMP) provided recommendations for an optimized preventative maintenance program and a rehabilitation/replacement program which specified recommended actions through 2020.
Since 2015, the City has implemented most of the high and medium priority recommendations from the AMP including both adjustments to maintenance practices and capital rehabilitation/replacement projects. The City now desires to update the AMP and develop a 10-year capital improvement plan for its water pump stations. This AMP update is presented as an Addendum to the 2015 AMP.
In March 2023, the City reported that the Rancho Solano 4 Pump Station experienced a catastrophic failure of the discharge manifold beneath the pump house slab. The failure was to assets not associated with this asset management plan update. The City is currently investigating the failed assets and the cause of the failure and will likely undertake a major rehabilitation of the facility. The evaluation of the Rancho Solano 4 Pump Station is included in this asset management plan update based on observations and analysis prior to the buried piping failure and the recommendations will be used to inform the scope of the rehabilitation of the facility.
1.2 Scope of Update
The AMP update includes assessment of 14 of the water pump stations evaluated in 2015 and an additional 2 pump stations not included in the 2015 evaluation. As shown in Table 1, each facility was visually assessed during a site visit and pump performance testing was performed to evaluate flow meter accuracy and to develop performance points (head and flow) of each pump. Additional assessment was performed as shown below:
• Detailed electrical assessments were performed at Rolling Hills, Rancho Solano Zone 4, and both the Rancho Solano Golf Course and Raw Water Pump Stations. Coating and steel thickness testing was performed at the Rancho Solano pumping stations, which were not assessed in 2015.
• A performance deficiency study was completed for pumps at several pump stations identified by the City.
• Facility capacity analyses were performed for Pressure Zones 2 and 4 to evaluate the existing pumping capacity of the Rolling Hills and Rancho Solano Zone 4 Pump Stations.

2.0 CONDITION ASSESSMENT
This chapter discusses the methodology used to assess the condition of the City’s pump stations and summarizes the assessment results.
2.1 Methodology
The condition assessment consisted of visual inspections, pump performance testing, and coating and steel thickness testing. The methodology for visual and pump performance testing followed the same approach as the 2015 study; these are summarized in the following sections. Coating and steel thickness testing methodology is discussed in detail.
2.1.1 Visual Condition Assessment
West Yost conducted site visits of the 16 pump stations between June 14 and June 21, 2022. The site visits were conducted by a condition assessment team that included the City’s Senior Instrumentation Technician, and engineers from West Yost. The team conducted visual inspections of the civil, structural, mechanical, electrical, and controls systems. The assessment team did not conduct confined space entries, destructive testing, or assessments of below grade piping, valves or appurtenances.
The team observed the external condition and performance of the facilities and equipment. Based on the observations, West Yost assigned a score to each component using the scoring index defined in Table 2-1 (Table 6 in 2015 AMP).
Table 2-1. Visual Condition and Performance Scoring Index Score Condition Score Index Performance Score Index(a)
1 Excellent Component functioning as Intended
2 Slight visible degradation In Service, but higher than expected O&M costs 3 Visible degradation In service, but function is 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 (a) Pump performance (capacity and efficiency) was assessed separately; see Section 2.2.2
2.1.2 Pump Performance Testing
Pump performance and efficiency testing was conducted by Pump Efficiency Testing Services (PETS) between June 14 and June 29, 2022. For each pump station, testing by PETS included the following:
• Pump Flow Tests – Testing included flow rate measurements using a portable ultrasonic flowmeter attached to the pump discharge piping, and suction and discharge pressure at three operating points. Measurements were taken for each pump at the City’s pump stations. The suction and discharge pressure measurements were used to calculate the total dynamic head (TDH) at each operating point.

• Flow Meter Verification – Up to 15 measurements were taken using the ultrasonic flowmeter, which were used to compare with the flow rate indicated on the City’s flow meters to verify City meter accuracy.
• Thermal/Infrared Images – Thermal image photographs were taken of the control panels and included the breakers, transformers, relays, motor starters, and rectifiers. • Energy Cost Savings Analysis – Using the flow and TDH measured during the pump flow tests, an analysis was conducted for each pump to determine the viability of replacing the pump with a more efficient unit.
2.1.3 Materials Testing
Concrete and metal condition assessments were performed by West Yost’s subconsultant, V&A Consulting Engineers (V&A), on June 21, 2022 at Rancho Solano Raw Water and Rancho Solano Golf Course Pump Stations. The V&A assessment followed the same rating system as the visual assessment. The methodology is described in detail in Appendix B and summarized below.
Concrete surfaces were observed visually for cracks, delamination, corrosion, and other concrete defects.
The surfaces were documented using digital, still photographs. Additionally, concrete sounding was performed within the buildings at both facilities to investigate for shallow, subsurface discontinuities.
Sounding was conducted using a hammer to strike accessible concrete surfaces and observing the qualities of the sound returned.
The condition of various metallic piping was evaluated using ultrasonic testing to assess the wall thickness; the effects of corrosion are identifiable when the wall thickness is measured less than the maximum, based on new pipe. Additionally, dry film thickness testing was performed on metallic piping and equipment components to determine the extent of protective coating deterioration.
2.2 Analysis and Results
This section presents the results from the visual condition assessments, pump performance testing, pump capacity deficiency analysis, and materials testing.
2.2.1 Visual Condition Assessment
The results of the condition assessment for each pump station are summarized in Appendix C.
Most of the mechanical equipment is in similar condition as was documented in the 2015 assessment, with slightly further deterioration noted. Some of the equipment has been replaced since the last assessment.
Although many of the pumps have been rebuilt over the years, most of them have outlived the typical useful life for centrifugal pumps. In general, the piping was found to be in marginally good condition with localized corrosion and coating deterioration noted. Several of the rubber pipe couplings were found to be deteriorating and in need of replacement. Several of the isolation valves were found to be moderately corroded with some evidence of leakage and need repair or replacement. Much of the electrical, instrumentation, and controls equipment are now past the useful life and in need of replacement.

2.2.2 Pump Performance Testing
This section presents the results of the performance testing completed for the pumps assessed and includes separate discussions for the capacity and efficiency observed for each pump.
2.2.2.1 Pump Capacity
Table 2-2 summarizes the measured flow and TDH and compares it to the pump name plate flow and TDH for each pump at each station. Appendix A presents the pump curves with the field-measured operating points indicated. Paradise Valley, Rancho Solano Zone 4, Rolling Hills, and Sanctuary 4 Pump Stations were identified by the City as having issues related to flow rates that are significantly less than the nameplate duty point. In addition to these four City-identified deficient stations, capacity deficiencies were observed at multiple other stations as part of the performance testing conducted. Deficient pumps are considered to be those delivering less than 82 percent of nameplate flow (deficient by over 18 percent). These pumps, along with the pumps at stations identified by the City as being deficient and are highlighted in Table 2-2.
These deficient pumps are analyzed in further detail in Section 2.2.3.2.
The City reported after performance testing that both pumps at Rancho Solano Zone 4 Pump Station are regularly operated with the downstream isolation valves in a partially throttled position. The pumps are normally operated in this manner to avoid amperage outside the service factor of 1.15 percent, which happens when the pumps are completely unthrottled. The normal pumping capacity under this operating condition is therefore much less than what could be achieved with fully unthrottled pumps.
It was also noted that the nameplate data for Pumps 1 through 3 at Goldridge Pump Station appear to conflict. More specifically, the nameplate flow and TDH are listed as 1000 gpm and 100’ TDH and the impeller diameter is listed as 10.69 gpm on each nameplate. However, based on the published pump curves, the listed nameplate flow and TDH should equate to an impeller diameter of approximately 12 inches. It is therefore unclear which pump curve should apply for these pumps. The measured operation points fall between the pump curves for a 10.69-inch and a 12-inch impeller diameter.

2.2.2.2 Pump Efficiency
Table 2-3 summarizes the measured wire to water efficiency, the calculated pump efficiency, and the theoretical pump efficiency for each of the pumps included in this study. The theoretical pump efficiency is based on plots of the measured pump operating points on the manufacturer’s performance curves.
Appendix A presents the detailed results of the testing including observed operating flow and head plotted on the pump curves used to estimate theoretical efficiency.
As discussed in the 2015 assessment, a typical clean water pump should have an efficiency of approximately 70 percent or greater when operating at its design point. Of the 55 pumps assessed, 31 had calculated efficiencies less than 70 percent, indicating significantly diminished operating efficiencies.
The 31 pumps and their facilities are highlighted in Table 2-3. The reduced efficiencies generally can be attributed to the pumps operating at points divergent from the associated nameplate duty point.
The 31 pumps and their facilities are highlighted in Table 2-3.

2.2.3 Preliminary Operational Analysis
Pump operation was analyzed based on pump curve performance and pump performance within the modelled system curve.
2.2.3.1 Preliminary Operational Analysis – Pump Curves
The first step to analyzing the operational performance was to assess the TDH and flowrate measured for each of the individual pumps and compare these values to the manufacturer’s published pump curve. A capacity deficiency could be indicated by two general scenarios, depending on where a given pump is operating relative to the published pump curve. Figure 2-1 illustrates the two general scenarios, which are further described below.
Scenario 1 is when the pump is operating along the pump curve, but farther to the left compared to the nameplate duty point. In this scenario, the actual flow rate is less than the nameplate flow, and the actual TDH is greater than the nameplate TDH. This scenario generally suggests greater head loss downstream of the pump moving performance left of the design operating point.
Factors that could cause increased frictional losses include but are not limited to:
• Valves that are inadvertently throttled instead of being completely open • Scale buildup on the interior walls of the pipelines
• Sediment accumulation along the length of the pipelines.
Scenario 2 is when the pump is operating at a point divergent from the pump curve with an actual flow rate that is less than the nameplate flow. In this scenario, the actual TDH could be more or less than the nameplate TDH, but since the pump is operating at a point below the pump curve, it is generally an indication that the pump has deteriorated to some degree.
Factors that could cause divergence of the pump performance from the manufacturer’s pump curve include but are not limited to:
• Recirculation of water within the pump due to worn seal rings between the impeller and the volute
• Wear or damage to the impeller
• Poorly seated valves of the non-operating pumps allowing some water to recirculate to the suction side
• Pump motor operating at speeds less than the design nameplate speed Potable Water Pump Station

Figure 2-1. Example Capacity Deficiency Scenarios
In addition to the pump performance testing results, data provided by the City was also used for four deficient stations identified by the City. City data for each pump station included actual overall flow rate in gallons per minute (gpm), and suction and discharge pressure in pounds per square inch (psi). The flow and pressure data were recorded by the City in five-minute increments between the dates of September 1, 2021, through September 1, 2022. This data did not distinguish flow and pressure per each individual pump, but rather was cumulative for the entire pump station. The data for Rancho Solano Zone 4 Pump Station included flow data for the date range listed above, but only included discharge pressure through May 5, 2022, and did not include any suction pressure data. Since the City data did not distinguish flow and pressure for the individual pumps, it was used primarily as a means to validate the results of the pump performance testing. Validation was accomplished by inferring which data points applied to a single pump operating; these specific data points were then compared to the operation points obtained from the pump performance testing.
As previously illustrated in Table 2-2, the measured flow rate for many of the pumps consistently differs from the associated nameplate flow. Table 2-4 presents a summary of the preliminary performance observations for these deficient pumps evaluated.

A detailed pump curve analysis was not conducted for this facility, as it is not owned by the City. Based on Pumps 1 and 3 also operating with less TDH than indicated on the nameplate, it is concluded there are no throttled valves or unintended additional TDH in the system, and that Pumps 1 and 3 are therefore operating below the pump curve (Scenario 2)
Southbrook 1 and 2 pump stations discharge to hydropneumatics tanks such that the system curve is flat delivering steady flow and head. Rancho Solano Raw Water pump station is not owned by the City and is not a part of the City’s hydraulic model. No additional analysis was performed to evaluate performance along the system curve at these facilities.

For the deficient pumps that operate on the pump curve but at higher TDH than the nameplate value, as a starting point it is recommended that the City confirm there are no valves that are inadvertently throttled downstream of the pumping station. As previously discussed, this is a common way for increased frictional losses to be induced into a pumping system and can be easily corrected. Additionally, for deficient pumps that are operating at points that are divergent from the pump curve, it is recommended to pull the pump and check the seal ring and impeller to verify whether they are damaged or worn; another recommendation is to verify whether the valves on the non-operating pumps are properly seated and do not allow recirculation.
These recommendations are included in Appendix C with a zero-cost value (recommended for Increased Maintenance/Operational Adjustments). It is assumed the recommendation will be performed as a maintenance effort.
The remaining pumps are further evaluated for system performance in Section 2.2.3.2.
2.2.3.2 Secondary Operational Analysis – System Curves
A secondary analysis was performed for facilities identified in Table 2-4 with the exception of Southbrook Pump Station 1 and 2 and Rancho Solano Raw Water as noted earlier. Using the City’s hydraulic model of the distribution system, West Yost developed system curves to determine the proper operating range along the pump curve. System curves were developed for a range of scenarios and was overlayed with the published pump curves to identify the range along the pump curve that the pumps should actually perform. This can confirm whether the pump is theoretically a suitable selection for the given system. A good selection is indicated by the point of intersection falling within the pump’s preferred operating region (POR), whereas a poor selection is indicated by a point of intersection falling outside the pump’s POR. A typical POR commonly accepted in the industry for centrifugal pumps is defined as a flow rate between 70 percent to 120 percent of the flow at the best efficiency point (BEP).
Following the assessment of the published pump curve relative to the modeled system curve, West Yost then considered the operating points measured during the recent pump performance testing with respect to the system curve. This step involved assessing where the operating points are located graphically with respect to the modeled system curve. If the operating points fall within the range of modeled system curves, it is a good indication that the City is operating the overall system in a consistent manner as assumed for preparation of the hydraulic model. If the operating points fall outside of the range of system curves, it is likely that the system is being operated in a manner that is inconsistent with the model. For example, valves could be unintentionally throttled, or additional flow could have been introduced at a location downstream from the pump station – both of these scenarios would result in additional TDH (and less flow) than expected based on the intersection of the system and pump curves. Plots of the modeled system curves overlaid with the published pump curves and measured operating points are provided with Appendix A.
Table 2-5 summarizes the results of the pump and system curve analysis, identifying pumps performing within the system curve range and also identify if the POR is within that range. Pumps should be operating within the system curve range and ideally the POR will as well for greatest efficiency.

Combining the results of the assessments described above and summarized in Tables 2-4 and 2-5 provide a relationship between two main points: whether the pump is operating on its pump curve; and whether the pump is operating within a range of flow/TDH that should be expected based on the modeled system curves. Different recommendations are drawn based on the answers to these two questions and can be generalized based on the four cases below.
General Scenario 1: Pump is operating on or very near its published pump curve and POR is within the range of modeled system curves. If measured operation is also within the range of modeled system curves, no action is recommended. If measured operation is outside the range of modeled system curves, further investigations are recommended.

November 2023
General Scenario 2: Pump is operating on or very near its published pump curve and POR is outside the range of modeled system curves. Since POR is outside the range of modeled system curves, pump replacement with one with a better fitting POR is typically recommended. Common issues under this scenario include additional frictional loss in the form of throttled valves, scale buildup, smaller piping diameter than what has been recorded, introduction of an undocumented flow addition downstream of the station.
General Scenario 3: Pump is operating off its published pump curve and POR is within the range of modeled system curves. Since the pump selection is theoretically suitable for the modeled system under this scenario, typical causes for operation off the pump curve include wear on the impeller, recirculation of flow through isolation valves or through the station PRV.
General Scenario 4: Pump is operating off its published pump curve and POR is outside the range of modeled system curves. Since POR is outside the range of modeled system curves, pump replacement with one with a better fitting POR is typically recommended.
This is illustrated in Table 2-6 below.
Table 2-6 General Pump Operating Scenarios
General Scenario Pump Operating on Performance Curve POR is within System Curves 1 Yes Yes
2 Yes No
3 No Yes
4 No No
For all cases, if the POR (between 70 percent and 120 percent of the BEP flow) falls within the range of modeled system curves, it is an indication of a good pump selection for the given system; similarly, if the POR falls outside the range of modeled system curves, it is an indication of a poor pump selection.

Where pump replacement is being recommended in Table 2-7, the duty point (flow/TDH) should be established, and replacement pump should be specified during design or following a detailed analysis of the hydraulic system and the overall station and pressure zone requirements. Similarly, where it is recommended to continue to run a pump to failure, a design or detailed analysis should also be performed once replacement is warranted.
Since desired pump performance was analyzed based on the City’s hydraulic model which assumes that all valves are not throttled for flow control and most pressure control stations are set at 40 psi (Rancho Solano 4 is set to 25 psi) West Yost recommends a field confirmation of isolation valves immediately downstream of each pump station to confirm if, and how much, valves may be throttled and the actual setting at control stations. Actual valve positioning and pressure control settings should be incorporated into the hydraulic model, new system curves developed, and pump recommendations provided in Table 2-7 confirmed. All pressure control stations should be confirmed. Table 2-8 illustrates the valves immediately downstream of the pump stations that should be investigated for control positioning.

3.0 CAPACITY ASSESSMENT
City staff identified the Rolling Hills and Rancho Solano Zone 4 Pump Stations as having possible electrical performance issues that would require upgrades to mitigate. If electrical upgrades are needed, the City intends to upgrade the electrical capacity to serve pumps sized for future buildout demand conditions.
This chapter describes the assessment performed to estimate future pumping capacity requirements of these facilities.
3.1 Assessment Approach
Pumping capacity is generally evaluated by pressure zone. Sufficient water delivery capacity into each zone should be provided by the City to meet the customer demands within the pressure zone. As shown in Figure 3-1, the Rolling Hills Pump Station, in coordination with the Paradise Valley and Martin Hill Pump Stations, serves Pressure Zone 2D. Rancho Solano Zone 4 Pump Station, along with Sanctuary 4 Pump Station, serves Pressure Zone 4. Therefore, the capacity of all pump stations serving Pressure Zones 2D and 4 were considered in this analysis.
A comparison of the available pumping capacity to the required future pumping capacity within Pressure Zones 2D and 4 are presented in this chapter. The assessment criteria, including pumping capacity requirements and buildout water demands, are described below.
3.1.1 Pumping Capacity Requirements
Sufficient pumping capacity, in conjunction with water storage reservoirs, should be provided by the City to meet peak customer water demands. As described in Section 3.1, the Rolling Hills and Rancho Solano Zone 4 Pump Stations serve Pressure Zones 2D and 4, respectively. Pressure Zones 2D and 4 are also served by additional pump stations and storage reservoirs, as shown in Figure 3-1.
Water system pumping capacity should be provided to meet the demands of the pressure zone. For zones with storage reservoirs, sufficient pumping capacity should be provided to meet the maximum day demand for the pressure zone. Water demands in excess of the maximum day demand (e.g., peak hour demand) are assumed to be supplied by the storage reservoirs.
The pump facility capacity analysis should also be conducted assuming the largest booster pump is out of service at each pump station (i.e., firm capacity of the pump station). This assumption ensures reliable deliveries during high demand conditions.
It is generally assumed that all pump stations serving a pressure zone are available to supply the zone.
This condition applies to Pressure Zone 4, which is supplied by both the Rancho Solano 4 and Sanctuary 4 Pump Stations. Based on discussions with the City, Pressure Zone 2D is not equally supplied by all three Zone 2D pump stations. Therefore, Zone 2D should be evaluated by regions of pump station influence— the west side of Zone 2D is primarily served by the Martin Hill Pump Station and the east side of Zone 2D is primarily served by the Rolling Hills and Paradise Valley Pump Stations. The Rolling Hills and Paradise Valley Pump Stations area of influence is assumed to encompass the eastern side of Pressure Zone 2D, with a western boundary running through the single 16-inch pipeline in Hillborn Road, between Sanctuary Drive and Fieldcrest Avenue. The Martin Hill Pump Station is generally unable to influence the areas to the east of this pipeline. Therefore, the pumping capacity analysis for Pressure Zone 2D, to include Rolling Hills Pump Station alone, was conducted for “2D East”.

3.1.2 Water Demands by Pressure Zone
Pumping capacity requirements are established based on water demands, as described in Section 3.1.1.
Existing water demands within Pressure Zones 2D and 4 were estimated using the City’s water system hydraulic model. Future additional demand expected at buildout was based on input from the City.
Existing and projected buildout water demands are further discussed in this section.
Existing water demands in Pressure Zones 2D and 4 were estimated using spatially located water meter data developed for the hydraulic model. Metered customer water demands were allocated into the hydraulic model in 2017 during hydraulic model development (using 2016 historical demands) and in 2020 during the latest hydraulic model update (using 2019 historical demands). Historical 2019 demands were slightly higher than historical 2016 demands (4 percent and 22 percent, respectively, for Zones 2D and 4). The slight increase in water demand from 2016 to 2019 would be anticipated based on a slight rebound in water consumption following the statewide 2012-2016 drought. Therefore, historical 2019 maximum day water demands of 1,870 gpm in Zone 2D and 450 gpm in Zone 4 were used as the baseline existing water demand for the pumping capacity evaluation.
Planned buildout land uses within Zones 2D and 4 were provided by the City via email on July 5, 2022. Neither zone was noted to have any known future development that should be considered as part of the pumping analysis. Therefore, no additional water demand due to buildout of the Pressure Zones was considered.
3.2 Results
Table 3-1 compares the existing available pumping capacity with the required pumping capacity for Zones 2D (East) and 4. Zone 2D East has an available firm pumping capacity of 5,600 gpm compared to an existing maximum day demand of 1,870 gpm, resulting in a surplus of 3,730 gpm, or approximately 200 percent of excess capacity. Similarly, Zone 4 has an available firm pumping capacity of 797 gpm compared to an existing maximum day demand of 450 gpm, resulting in a surplus of 347 gpm, or approximately 77 percent of excess capacity. As described previously, there is little to no new future development identified in Zones 2D and 4. Therefore, sufficient pumping capacity exists to meet the existing and future buildout demand. No capacity upgrades are recommended until the projected future maximum day demands exceed the surplus capacity presented in Table 3-1.
This capacity evaluation assumes full design performance ability of the existing pumps. The individual pumping capacity presented in Table 3-1 is based on each pump’s design operating point. During discussions with the City, it was noted that the Rolling Hills and Rancho Solano 4 Pump Stations are regularly operating at a lower capacity than is shown in the table. The reduced actual capacity exhibited by the pumps could be due to the pumps not operating near their design points or could be due to reduced efficiency caused by general wear and tear. Causes for and recommendations to improve the reduced pumping capacity are discussed in Chapter 2. Recommendations provided in Chapter 2 should be implemented. If pumps are replaced, a minimum capacity equal to the required pumping capacity noted in Table 3-1 should be provided.

(a) Pump capacity corresponds to the design point of each pump. (b) Firm pumping capacity is defined as the total pumping capacity with the largest pump unit at each facility out of service. (c) Available pumping capacity assumes firm pumping capacity at all pump stations. (d) Required pumping capacity is equal to the maximum day demand of the pressure zone (for zones with storage, such as Zones 2D and 4), in addition to the maximum day demand of any pressure zones without storage that are served from the zone (e.g., Zone 4 includes the maximum day demand of the upper Zone 5, which does not have storage). In zones with storage, water demand greater than the maximum day demand (e.g., peak hour demand, fire flows) is drawn from water storage reservoir(s). It is assumed that the City’s Pressure Zone 2D and 4 water storage reservoirs have adequate storage available to serve emergency, fire, and operational storage requirements.
(e) The maximum day demand presented is based on metered average day demand spatial distribution from 2019, scaled to historical (2019) maximum day demand.
(f) Based on discussions with the City, the required pumping capacity for Zone 2D considers only the eastern portion of the pressure zone that is directly served by the Rolling Hills and Paradise Valley Pump Stations. Although the Martin Hill Pump Station also supplies the western portion of Zone 2D, the east and west areas of Zone 2D are only connected by a single 16-inch pipeline in Hillborn Road that isolates each side of the zone. Martin Hill Pump Station is generally unable to influence the areas to the east of this pipeline.

4.0 RISK ASSESSMENT
This chapter describes the updated risk assessment that was used to prioritize the replacement or rehabilitation actions for both components and pump stations.
4.1 Methodology
The 2015 risk assessment developed likelihood of failure, consequence of failure, and risk scores for each individual component asset, and each pump station as a whole. During preparation of this AMP Update, the City initiated an update to their Potable Water Master Plan (PUMP), which included condition and risk assessment of other asset types (pipelines, reservoirs, treatment plants). As part of the PUMP Update, a risk assessment methodology was developed, which differed from the 2015 AMP. The City agreed to employ the risk methodology developed during the PUMP Update in this AMP Update1. The general approach is illustrated in Figure 4-1. As indicated in the figure, a rating for both likelihood and consequence of failure was given to each individual component asset (bottom row). The likelihood and consequence of failure methodologies for components as defined in the 2015 risk assessment have been maintained in this AMP Update. The aggregate of the likelihood results from components within a given pump station is then used to determine the likelihood of a pump station failure. Pump station likelihood is then combined with the consequence of failure rating of each pump station to determine a comprehensive risk rating for each pump station as a whole.
Figure 4-1. Pump Station Risk Assessment Methodology
Components and pump stations are then assigned a risk level, from Low to High, based on a risk level matrix. The PUMP Update also refined the City’s risk level matrix from the 2015 AMP; the updated risk level matrix is presented in Figure 4-2.
1 The primary reason for employing the PUMP Update risk approach was that the 2015 AMP study evaluated pump station likelihood of failure using a relative ranking of the components in that pump station compared to all components in all City pump stations. This approach uses a relative ranking and cannot be applied consistently if the set of pump stations being evaluated changes (as it did in this AMP Update compared to the 2015 AMP).

In summary, the changes from the 2015 AMP methodology included in this update are:
• Updated approach for calculating pump station likelihood of failure (details in Section 4.2.3.1).
• The likelihood of failure range for pump stations was 1-5 in the 2015 AMP. This has been changed to a range of 2-10 to align with the PUMP Update. • Revisions to the risk level matrix (Figure 4-2)
• Additional assets included in the assessment (several assets were added to the assessment from facilities in the 2015 AMP, to provide a more comprehensive assessment) For this update, the risk assessment was performed using the framework established in the PUMP Update and results of the 2022 condition assessment efforts. The database model used in 2015 was updated with any new assets or condition information.
Risk results were used to prioritize the rehabilitation, replacement, or maintenance actions to meet established service reliability and performance goals.

4.2 Results
The results of the updated risk assessment are presented in the following sections by component and pump station. Appendix C also presents the risk results for each component, by pump station.
4.2.1 Component Risk Levels
Table 4-1 presents the total number of components that fall into each risk level category. The majority of pump station components are Medium-Low risk (43-percent of all assets). The risk results from the 2015 study are not shown because the updated risk results are not directly comparable due to the changes noted earlier.

4.2.3 Facility Risk Levels
The risk for each facility was evaluated based on the consequence of failure of the facility, as well as the combined likelihood scores of the components within each facility, as described below.
4.2.3.1 Facility Likelihood
The likelihood of failure for each facility was evaluated using the likelihood of failure scores of individual components within each pump station, weighted by their respective nominal monetary value.
An asset value weight was assigned to each component, as shown in Table 4-2.

<$5,000 0.3
$5,000-$20,000 0.7
>$20,000 1.0
This value weighting considers that components of a higher value or importance (e.g., a pump) will have a greater impact on overall facility likelihood of failure than assets of lower value or importance (e.g., a field instrument or sump pump). Overall facility likelihood of failure scores were determined by first weighting the likelihood of failure scores of each individual component using the weighting factors shown in Table 4-2. The resulting weighted likelihood of failure scores for each component were then added together and divided by the sum of the weighting factors. This algorithm produces an overall likelihood of failure score between 2 and 10 for a given facility, in a manner similar to the likelihood of failure scoring for the individual components.
4.2.3.2 Facility Consequence
The consequence of failure of a given facility takes into account the impacts to the system should a that facility fail. Consequence of failure factors from the 2015 AMP were maintained and included: Community Disruption (evaluated by the type of customers in each Zone); and Service Reliability (evaluated based on the ability to meet demand scenarios in an outage/failure). Some consequence of failure scores changed from the 2015 AMP, but most remained the same as there were not significant changes to land use or system configuration/supply. Similar to the scoring for components, facility consequence of failure is rated on a 2 to 10 scale.

5.0 UPDATED ASSET MANAGEMENT PLAN RECOMMENDATIONS
This chapter provides recommended improvements based on the assessment results described in the preceding chapters. The action plan matrix developed in 2015 (see Figure 5-1) was used as a guide to identify maintenance, near-term rehabilitation/replacement, or long-term rehabilitation/replacement needs. The condition rating and remaining useful life are used to determine the asset’s physical mortality score; performance rating and maintenance frequency are used to determine the asset’s level of service score. Refer to the 2015 AMP for details on how these ratings are used to determine each score. The action plan for each asset is shown in Appendix C.
Figure 5-1. Action Plan Matrix
Assumptions considered in the development of the Action Plan recommendations include:
• Engineering judgment was employed in the interpretation of Figure 5-1, including but not limited to the pump performance testing and operational analysis presented in Section 2.2. • Components that require replacement of a small piece of the component (e.g., replacement of backup batteries in an MCC; replacement of pipe nipple connecting valve and piping, etc.), were recommended for Increased Maintenance / Operational Adjustments, and details are provided in Appendix C Recommended Improvements.

• Costs were developed at Class 5 AACE level estimate. Unit costs were reviewed and updated from the 2015 values. Overhead amounts included:
— Construction and installation – 50 percent of material cost (same as 2015) — Administrative, legal, engineering, and construction management contingency of 35% was applied to both the material cost and construction/installation cost (was only applied to material cost in 2015).
— Overhead and profit contingency of 20 percent was applied to both the material cost and construction/installation cost (was only applied to material cost in 2015). — Contingency of 30 percent was applied to both the material cost and construction/installation cost (was only applied to material cost in 2015).
5.1 Recommended 10-Year Rehabilitation/Replacement Program Components that require rehabilitation or replacement were developed into improvement projects by pump station. These requirements consider the recommendations developed in Table 2-7 for replacement of pumps based on performance as well as the risk analysis completed in this section which addresses overall LOF and COF of various facility assets. Table 5-1 presents an optimized program for the next ten years based on the risk levels determined in Section 4 and the Action Plan presented above. The capital program is valued at approximately $8.3M representing approximately $3.0M in asset replacement and approximately $5.3M in rehabilitation.
Asset replacement and corrective action/rehabilitation for each facility are summarized in Table 5-2. Note the recommendations for Rancho Solano Zone 4 are based on the analysis herein, although the City has completed many improvements since the March 2023 failure.

5.2 Recommended Next Steps
The City has proactively implemented the recommendations from the 2015 AMP and will further build upon that progress as they implement recommendations from this update. The following recommendations will allow the City to continue to use this AMP to guide future asset management of the pump stations:
• Complete the evaluation of Rancho Solano 4 pump station catastrophic failure in March 2023 and incorporate these recommendations into its capital rehabilitation planning. • Budget for and implement the replacement and rehabilitation recommendations outlined in this report and summarized in Table 5-1.
• Continue to track condition and performance of assets to develop trends, which will allow the City to make informed maintenance and asset management decisions. • Conduct future updates of the AMP similar to the process undertaken in 2022/2023.

1 Introduction
V&A Consulting Engineers (V&A) was retained by West Yost & Associates (West Yost) to perform a condition assessment of two water pump stations (PS) within Rancho Solano, in Fairfield, California.
Figure 1-1 shows an aerial map with the locations of the two pump stations.
The condition assessment is part of a follow-up study performed by West Yost in 2015. The Rancho Solano Golf Course (Golf Course PS) and Raw Water Pump Stations (Raw Water PS) were originally not owned by the City at the time of the study. Now that the City has taken over ownership of these facilities, the City is in need of establishing a baseline condition of the two pump stations.
The Raw Water Pump Station was constructed in 1988 and has undergone multiple rehabilitation of the pump system. The Golf Course Pump Station was constructed circa 1990.

2.1 Visual Assessment
Qualitative visual evaluations were conducted from inside and outside of the pump stations, focusing on the condition of concrete surfaces and piping. Cracks, delamination, corrosion, and other concrete defects referenced in American Concrete Institute (ACI) 201.1R-92, “Guide for Making a Condition Survey of Concrete in Service” were documented with digital, still photographs. The condition of metal components and coatings were also evaluated and documented. Much of the visual assessment data is subjective and is based upon V&A’s extensive experience evaluating concrete and metallic structures in the water and wastewater industries. Standardized ratings used to characterize condition were assigned based on the VANDA Concrete and Metal Condition Indices, as shown in the subsequent sections.

2.1.1 VANDA® Concrete Condition Index
V&A created the VANDA Concrete Condition Index (Table 2-1) to provide consistent reporting of corrosion damage based on objective criteria. Concrete condition is rated from Level 1 to Level 5 based upon field observations and measurements, with Level 1 indicating the best case and Level 5 indicating severe damage. The individual criteria are applied based on engineering judgment to arrive at the overall rating.

2.2 Concrete Assessment Methods
2.2.1 Sounding
Sounding was performed within the structures at the evaluator’s discretion to investigate for shallow, subsurface discontinuities. Using a hammer to strike accessible concrete surfaces, the sound can indicate if defects such as voids, delamination, or honeycombing are present. The sound returned from solid concrete without subsurface discontinuities is a sharp “ping” noise. A “hollow” sound generally means that a discontinuity exists beneath the sounding location. A soft “thud” typically results from deteriorated concrete.
2.3 Metal Assessment Methods
2.3.1 Ultrasonic Testing
Ultrasonic testing (UT) is a non-destructive evaluation technique used for the determination of metal wall thickness. High-frequency sound waves are transmitted through one side of a metal wall from a transducer. When the sound waves reach the other side of the metal wall, a fraction of the waves will echo back to the transducer. The metal thickness is determined by recording the time it takes for the sound wave to travel through the metal and return.
A-scan point measurements were performed for various metal structures and piping. For pipes, measurements were made around the pipe circumference and were referenced to clock positions (e.g., 12:00, 3:00, 6:00, or 9:00) viewed in the downstream direction (Figure 2-1).
If pitting or extremely localized corrosion is found, a pit depth gauge will be used since UT will not provide acceptable readings due to the rough surface.
Figure 2-1. Clock Positions on Pipe Looking
Downstream
To determine the amount of corrosion that has occurred from UT data, the original measured thickness of the pipe must be known. The thickness measurements recorded to assess corrosion can then be compared against the original thickness measurements. For this project, the original thickness of the piping, based on the measurements was unknown; so the original wall thickness was determined using the following procedure:
1. Group the thickness readings by the specified pipe for the process area, material, diameter, and service.

2. Visually exclude outliers above the top of the core grouping of thickness measurements. These may be anomalous measurements that are slightly thicker than the typical original thickness of the pipe.
3. Assume that the consistent thickness readings that remain reflect the original thickness of the metal.
a. For steel pipes, the standard thickness from ANSI B36.10was used as the nominal thickness. b. For cast and ductile iron pipe, if the pipe was not marked with the class or specified in the contract documents, the nominal thickness that was assumed based on the nearest standard average thickness per ANSI/AWWA C150/A21.5. For grooved end pipe with couplings, the limitations of AWWA C115 (i.e., minimum Class 53) were also applied to the nominal thickness selection
The specific nominal thickness and tolerance selected for each test location are shown with the UT testing results. It should be noted that if the measured thicknesses are within the tolerances that were likely to have been applied during the manufacture of the piping, thickness measurements below nominal are not necessarily an indication of corrosion and may be considered minor corrosion.
To an extent, this method implies that the internal corrosion is non-uniform across the surfaces so that the difference between the maximum thickness measurements and the minimum thickness measurements is representative of corrosion rate due to pitting or otherwise localized corrosion.
2.3.2 Dry Film Thickness
Dry film thickness (DFT) is the thickness of a coating or lining after it has cured. A DFT gauge uses electromagnetic induction or eddy current technology to measure the thickness of a wide variety of coatings on metal surfaces. V&A used a gauge that can measure coatings up to 0.2 inches (2 00 mils) in thickness, and the gauge was calibrated using shims prior to the collection of data. Measurements were taken on metallic components in the same manner as described for ultrasonic testing in Section 2.3.1.

3 Results
3.1 Rancho Solano Golf Course Pump Station
3.1.1 Visual Assessment
The Rancho Solano Golf Course pump station consists of a concrete masonry building, three pumps that feed water through a combined discharge pipe to two filtration units, and associated coated steel and ductile iron piping, valves, and controllers.
In general, the concrete surfaces of the pump station were in VANDA Level 1 condition. Sounding was performed on the station’s walls and floor. No signs of concrete spalling or delamination were observed during the assessment.
The metal components and piping were in VANDA Level 2 condition excluding the metal cabinet shown in Photo 3-2, which was in VANDA Level 4 condition. Table 3-1 presents a summary of observed defects at the pump station. The noted defects included:
▪ Minor corrosion of the pump discharge piping, see Photo 3-1; ▪ Severe surface corrosion on a metal cabinet and the metal platform beneath, see Photo 3-2. ▪ Surface corrosion on the bottom of the bladder tank in contact with the metal platform , see Photo 3-3.
▪ Surface corrosion of a ductile iron tee, see Photo 3-4. ▪ Surface corrosion on the bottom panel of the electrical cabinet and leg supports, see Photo 3-5 and Photo 3-6.
▪ The coating of the metal platform was generally in good condition except at locations in contact with mounted structures. This is likely attributed to dissimilar metals. ▪ Coating deterioration was observed on the supports of equipment as shown in Photo 3-1, Photo 3-2 and Photo 3-5.
▪ Water leakage was observed coming from the filtration unit shown in Photo 3-7. The water leaking from the unit may promote corrosion of surrounding metallic components.

3.1.2 Ultrasonic Thickness Testing
Ultrasonic thickness measurements were recorded on the accessible steel pipe on the main floor.
Measurements were recorded in bands along the circumference of the pipeline (4 circumferential readings per band) spaced at regular intervals. The thickness measurements and associated conclusions only apply to where the readings were taken. The nominal thickness of the piping is not known; therefore, an assumed nominal thickness, based on ANSI B36.10 for standard steel pipe and ANSI/AWWA C150/A21.5 for ductile iron were used to determine the metal loss.
UT measurements are summarized in Table 3-2. The maximum measured metal loss on the 66-inch pipe was 8%, which is considered minor solely based on metal loss. The metallic assets were classified as VANDA Level 2 condition.
