ES EXECUTIVE SUMMARY
V&A Consulting Engineers, Inc. (V&A) was retained by Carollo Engineers, Inc. (Carollo) to conduct a condition assessment of the Buena Vista Pump Station (BVPS), the Buena Creek Pump Station (BCPS), and the Raceway Pump Station (RPS). Thes e stations are owned by the City of Vista and Buena Sanitation District, and operated by the Encina Wastewater Authority. The intent of the assessments are to assist in preparing Preliminary Design Reports for the three pump stations which will outline capital projects and plan budgets for future fiscal years. Concrete surfaces, piping, motors, and pumps were evaluated in each of the three pump stations. The assessment methods used to assess these features are as follows:

Actions carried out on September 9, 10, and 11, 2015:
x Visual evaluation of the concrete surfaces an d metal piping and appurtenances in the BCPS and BVPS dry wells using digital photographs to document notable observations. x Visual evaluation of coatings on concrete and metal structures x Pit depth measurement on corroded metallic surf aces in the BCPS and BVPS dry wells and on above grade RPS piping.
x Pipe wall thickness measurements using an ultrasonic testing gage for dry well piping in the BCPS and BVPS dry wells, and on above grade piping at the RPS. x Rating the evaluated concrete and metal surfaces using the VANDA ® Concrete and Metal Condition Index
x Motor and pump vibration analysis by Reed Electric at BCPS and BVPS Actions carried out on January 12, 2016:
x In-situ soil resistivity testin g along the 16-inch diameter force main and 14-inch diameter excess effluent pipeline alignments for the BC PS. Cursory foreign utility investigation along both ductile iron pipelines (DIPs) for potent ial cathodically protected structures. After potholing over the pipeline, collected three soil samples at pipe depth for corrosivity analysis.

Soil samples were laboratory tested for as-rec eived and saturated (minimum) soil resistivity, pH, and soluble chloride, sulfate, and bicarbonate ion concentrations. 05/13/2025 C9 693 of 1078

The evaluated concrete surfaces are in
good condition. However, there was
evidence of infiltration at the pipe
penetrations and on the south wall of the
dry well.

The evidence of groundwater infiltration on
the concrete walls and the corrosive soil
environment the pump station is located in

Metal surfaces are in good condition with
the majority of the coating (about 90% )
intact. There is some copper piping t hat is
significantly corroded.

Repair damaged coating on mechanical
equipment and piping as needed. Clean
the surfaces of the copper piping and
determine if the replacement of copper
piping is warranted.
3 to 5
At most of the testing locations, the
ductile iron pipe is in good condition.

There were a few locations that showed
wall thickness outside the manufacturing
tolerances by what is considered a minor
degree. No significant exterior corrosion
or leaks were observed on the rest of the
piping in the dry well, which was outside
the ultrasonic testing areas.

Routine assessment.

The inverted pendulum arrangement of
the motor and pumps appears to be a
significant issue with respe ct to seismic
loading.

Evaluate the seismic vulnerability of the
motor and pump arrangement. 0 to 2
Vibration levels are high on most motor

Timeframe (years)
In general, the concrete interior surfaces
of the dry well were in good condition.

There were, however, some isolated areas
of groundwater infiltration, some with
staining indicating possible corrosion of
the reinforcing steel. The grout pads
under the pump b ases showed
deterioration at the edges in some cases.

Monitor areas of infilt ration within the dry
well for increased evidence of infiltration or
corrosion staining. Consider further
evaluation of the concrete and reinforcing
steel in areas where there is corrosion
staining.
0 to 2
The coating on the piping was generally in
good condition at higher elevations, with
numerous chips and other defects in the
coating at lower elevations. Generally,
there was minor surface corrosion where
the coating was damaged. There was also
one spool downstream of Pumps 1 and 2
that exhibited moderate external
corrosion.

Repair damaged coating on mechanical
equipment and piping as needed.
0 to 2
At most of the ultrasonic thickness testing
locations, the dry well pipin g is in good
condition, but there was one location on
the header downstream of Pumps 1 and 2
that exhibited a significant thickness loss
of 37%. This location also exhibited
external corrosion. It is possible, though
considered unlikely, that the pipe at t his
location was manufactured thinner than
required by AWWA standards. No
significant exterior corrosion or leaks were
observed on the rest of the piping in the
dry well, which was outside the ultrasonic
testing areas.

Calculate the minimum required thickn ess
for the piping based on pressure, loading,
etc. Compare the minimum required
thickness against the measured
thicknesses in this report to determine the
amount of further wall loss that can be
tolerated, if any, before the integrity of the
piping is imp aired. With the results of this
analysis in mind, consider activities to
address corrosion and int egrity of the dry
well piping:

The bathroom drain piping and ventilation
ducting exhibited various moderate -
severity defects.

Repair the bathroom drain piping and
ventilation ducting connections. 0 to 2
The meter vaults show moderate to
extensive groundwater infiltration, with
staining that indicates possible corrosion
of the reinforcing steel. The vaults are
only a few years old. The extent of staining
may indicate that the water leaking into
the vaults is brackish, which would
promote corrosion.

Perform testing to quantify the extent of
degradation of the concrete and
reinforcement in the two meter vaults.

Testing to consider is similar to that
recommended for the dry well. Sample the
water entering the vaults for resistivity and
chloride content.

CConclusion Recommendation Implementation
Timeframe (years)
The piping, pipe supports, sump pump
fittings, and electrical items within the
meter vaults also showed various defects
that appear to be relate d to the
groundwater infiltration, particularly if it is
brackish.

1. Address the electrical connections
within the meter vaults (meter
ground cables and power for
sump pump). Replace corroded
connectors with corrosion -
resistant materials and take
precautions for galvanic corrosion
between dissimilar metals.

2. Replace the cam- lock fittings for
the sump pump in the south
meter vault.

3. Assuming that the groundwater
entering the meter vaults is
brackish, use materials and
coatings suitable for a marine
environment for all items within
the vaults.

4. Consider whether the groundwater
may also be aggressive to the
buried DIP force mains within the
pump station site, review the
construction details for the force
mains to determine whether
adequate corrosion protection
was provided for the buried pipe.

Consider conducting field
evaluations to determine the
corrosivity of the soil and/or the
condition of the buried DIP.

1.0 INTRODUCTION
V&A Consulting Engineers, Inc. (V&A) was retained by Carollo Engineers, Inc. (Carollo) to conduct a condition assessment of three pump stations for the City of Vista (City) and the Buena Sanitation District (District). The pump stations of interest are the Buena Vista Pump Station (BVPS), the Buena Creek Pump Station (BCPS), and the Raceway Pump St ation (RPS). The BVPS is located in Carlsbad, California, and the BCPS and the RPS are located in Vista, California. These pump stations are part of four pump stations that convey water to the Encina Wastewater Authority’s (EWA) Water Pollution Control Facility. The EWA operates these pump stat ions for the City and the District. The BVPS and RPS are in the City service area, and the BCPS is in the District service area. Figure 1—1 is an aerial view of the pump station locations.

V&A Project No. 15-0024 Introduction 7

The City and District wish to assess the condition of assets in the wastewater conveyance system for rehabilitation planning and providing the necessary upgrades to improve the safety, reliability, and efficiency of the stations, and meet current applic able treatment codes, standards, and guidelines.

V&A’s assessments are intended to provide informat ion to assist Carollo in preparing Preliminary Design Reports for the three pump stations. The assessment consisted of the following actions, which were carried out between September 2015 and January 2016:

x Visual evaluation of the concrete surfaces an d metal piping and appurtenances in the BCPS and BVPS dry wells using digital photographs to document notable observations. x Visual evaluation of coatings on concrete and metal structures x Pit depth measurement on corroded metallic surf aces in the BCPS and BVPS dry wells and on above grade RPS piping.
x Pipe wall thickness measurements using an ultrasonic testing gage for dry well piping in the BCPS and BVPS dry wells, and on above grade piping at the RPS. x Rating the evaluated concrete and metal surfaces using the VANDA ® Concrete and Metal Condition Index
x Motor and pump vibration analysis by Reed Electric at BCPS and BVPS x In-situ soil resistivity testin g along the 18-inch diameter force main and 14-inch diameter excess effluent pipeline alignments for the BC PS. Cursory foreign utility investigation along both ductile iron pipelines for potential cathodically protected structures. After potholing over the pipeline, collect three soil samples at pipe depth for corrosivity analysis. Soil samples were laboratory tested for as-received and saturated (minimum) soil resistivity, pH, and soluble chloride, sulfate, and bicarbonate ion concentrations.

The assessment approach is described in more detail in Section 2.0.

2.0 ASSESSMENT APPROACH
V&A uses both qualitative and quantitative means to evaluate structures and their components. The condition assessment utilized the methods and techniques described in this section.

2.1 Access
The dry wells accessed during the assessments are not confined spaces, yet V&A personnel wore 4- gas monitors as a precautionary measure. Piping and concrete surfaces intended for evaluation were accessible while standing on the dry well floors. A ladder was used when needed to reach and evaluate concrete and metal surfaces. Above grade piping and other components were easy to access on foot and did not require ladders or scaffolding. The assessment team members wore the appropriate personal protective equipment while on-site, which included steel-toed shoes, safety glasses, gloves, and hard hats.

2.2 Visual Assessment
The visual assessment focused on the condition of concrete and metal surfaces. Observations such as exposed aggregate, cracks, and evidence of corrosion were recorded when found, supplemented with digital photographs. Pipeline joints were evaluated for offsets, leaks, gaps, and other notable items if found. It should be noted that the assessment of concrete for this project was limited to a visual evaluation. Physical and quantitative testing was not performed for the concrete surfaces. 05/13/2025 C9 700 of 1078

2.3 Ultrasonic Thickness Testing
V&A conducted ultrasonic thickness testing on the piping in the dry wells at the BCPS and BVPS, and on the above-
grade header piping at the RPS. Ultrasonic thickness
testing is a non-destructive evaluation technique that
allows for the determination of metal wall thickness. High- frequency sound waves are transmitted through one side
of a metal wall from a transducer. When 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 reco rding the time it takes for the sound wave to travel through the metal and return.

V&A used an Olympus ultrasonic thickness gauge to obtain thickness measurements for the metallic piping (Photo
2-1). Prior to taking measurements, the gauge was
calibrated to the velocity of sound in ductile iron or steel, as appropriate. The type of testing that was conducted is known as A-scan, which gives the wall thickness at a single point at each measurement location. It should be noted
that the wall thickness at other locations may vary. Test locations were chosen to provide a representative
condition of the entire pipe surface. Testing was performed on accessible piping (i.e. able to be reached without a ladder/scaffolding/confined space entry).

2.3.1 Wall Thickness Loss Analysis
The classes and nominal thicknesses of the pipe and fittings used at the pump stations were unknown. The wall thickness loss was calculated based on the nominal thickness and the associated casting tolerance from the ductile iron pipe (DIP) standards that were assumed to be applicable. The nominal thickness defines each class of pipe or fitting and is used in specifying and ordering. The casting tolerance is a “minus” tolerance given by the applicable standard, allowing the pipe or fitting to be thinner than the nominal thickness at manufacture. If the measured thicknesses are within the casting tolerance, variations in thickness at a gi ven location are not necessarily an indicator of corrosion.

Since the pipe spools that were tested had thread ed flanges or grooved ends, they are assumed to have been made from Class 53 ductile iron pipe, or thicker, per the requirements of AWWA C115, "Flanged Ductile-Iron Pipe with Threaded Flan ges," and AWWA C606, “Grooved and Shouldered Joints.” It should be noted that the piping was not evaluated for pressure or other loading considerations. Higher pressures, for example, coul d have dictated a need for pipe that was thicker than the minimum class allowed by these standards, which are based on manufacturing considerations.

In addition to the ductile iron pipe spools that we re tested, steel rectangular suction lines at the BVPS and ductile iron elbows at the RPS were also tested. The nominal thickness for the steel rectangular components was unknown, so they were assumed to have been fabricated from fractional-inch plate. The nominal thickness and ca sting tolerance for the ductile iron elbows were taken from AWWA C110, "Ductile-Iron and Gray-Iron Fittings,” for Class 250 ductile iron fittings.

2.4 Pit Depth Measurements
Where pitting was observed on the exterior of
the piping, pit depths were measured using a
handheld pit depth gage (Figure 2—1). The
gage is held in a vertical position above the pit
to be measured with the lower edge flush
against the metal surface. The claw is inserted
into the pit. The pit depth is read on the dial at
the right hand side of the gage.

2.5 Vibration Analysis
Reed Electric & Field Services was retained to pe rform vibration tests for the motors and pumps at the BCPS and BVPS. The RPS has submersible pump s, so testing was not performed there. The intent of testing is to screen for maintenance and repair activities. The vibration tests were performed for Pumps and Motors 1, 2, 3, 4, and 5 at the BCPS and the BVPS. Motor 3 at the BCPS experienced Variable Frequency Drive (VFD) or other electrical issues, and the testing was aborted.

A four-channel data recorder and analyzer were used with three magnetic-mount accelerometers and a laser speed tachometer to monitor vibration and motor speeds in revolutions per minute (rpm).

Sensors were mounted as shown in Figure 2—2 on the motor upper bearing, motor lower bearing, pump upper bearing, and pump lower bearing in th e in-line, perpendicular, and axial directions.

System control limitations allowed data to be collect ed only at certain pump speeds for several test points. The following data was recorded for each test performed at both pump stations:

x Overall velocity and displacement vibration
x Velocity spectrum plots
x Filtered amplitude/phase measurements where the tachometer was available

The test observations and Reed Electric’s recommendations for future monitoring and evaluation are presented in the Findings sections for the BCPS and the BVPS assessments.

2.6 In-Situ Soil Resistivity

2.6.1 Wenner Four-Electrode Method: General Information Understanding how easily current will travel thro ugh a medium surrounding a metallic object is important in evaluating the corrosivity of the envi ronment. Resistivity is an inverse measure of the ability of a soil to conduct an electric current, wi th higher resistivity resulting in a lesser degree of current flow. Corrosion rate depends on current flow between a metal and the adjacent medium.

Normally, the corrosion activity on metals in soil increases as soil resistivity decreases.

Soil resistivity measurements were conducted in accordance with ASTM G57, “Standard Test Method for Field Measurement of Soil Resistivity Using the Wenner Four-Electrode Method.” The Wenner method involves the use of four metal electrodes (p ins) driven into the ground along a straight line, equidistant from each other, as shown in Figure 2—3. At each of the two excavation locations, soil resistance measurements were recorded at pin spacings of 5, 7.5, 10, 15, and 20 feet.

An alternating current from the soil resistance meter causes a current to flow through the soil between the outside pins C1 and C2. The soil resistance creates a voltage gradient, which is proportional to the average resistance of the soil mass to a depth equal to the distance between pins. The voltage drop is then measured across pins P1 and P2, and the soil resistance (in ohms) is calculated by the soil resistance meter. Resistivity of the soil (in ohm-cm) is then computed from the instrument reading using the procedure described in Sections 2.6.2 and 2.6.3.

Figure 2—3. Wenner Four-Electrode Method Schematic

2.6.2 Soil Resistivity Calculation – to Depth
In the Wenner four-electrode method, the average resistivity of the soil mass below the pins, to a depth equal to the pin spacing, is calculated with the equation ρ = 2 ∙ π ∙ A ∙ R,
where ρ = average soil resistivity to a depth of A (ohm-cm), A = distance between electrodes (cm),
R = soil resistance to a depth of A, soil resistance meter reading (ohm), and π = 3.14 (approximately).

The resulting resistivity value represents the average resistivity of the soil below the pins to a depth equal to the pin spacing. This average resistivity va lue includes the effect of soil layers near the surface. The Barnes layer method, described below in Section 2.6.3, allows the resistivity of each soil layer below grade to be calculated without the effect of shallower layers.

2.6.3 Soil Resistivity Calculation – per Layer (Barnes Method) The Wenner four-electrode method, described abov e in Sections 2.6.1 and 2.6.2, determines the average soil resistivity from grade to a depth equal to the pin spacing. These results can be expanded using the Barnes layer meth od to remove the effect of shal lower soil layers and arrive at the resistivity of each soil layer individually. For example, the average resistivity of the soil layer between 5 feet and 10 feet deep may be calc ulated using the four-electrode resistance measurements for the 5- and 10-foot depths.

The results of the Barnes layer calculations are used to evaluate the corrosivity of the soil in lieu of the average resistivity from grade to a given depth. The Barnes layer method isolates the layer of soil that a particular structure will be in contact with, whil e neglecting the soil in layers that will not be in contact with the structure. The soil layers that are no t in contact with the structure will have little to no effect on the corrosion rate of the structure. Soil corrosivity as a function of soil resistivity is discussed in Section 2.7.

In the Barnes layer method, the soil layer resistance (RA-B) is first calculated using the equation

RA-B = (RA ∙ RB) / (RA – RB),

where RA-B = soil layer resistance from depth A to depth B (ohms), RA = soil resistance to depth A, soil resistance meter reading (ohms), and RB = soil resistance to depth B, soil resistance meter reading (ohms).

Next, the average soil layer resistivity (ρA-B) is calculated using the equation

ρA-B = 2 ∙ π ∙ (B – A) ∙ RA-B,

where ρA-B = average resistivity of soil layer between depth A and depth B (ohm-cm), A = depth below grade to the top of the soil layer (cm), B = depth below grade to the bottom of the soil layer (cm), π = 3.14 (approximately), and
RA-B = soil layer resistance from depth A to depth B (ohms), as determined above.

2.7 Soil Sample Analysis
A wide variety of water-soluble salts is typically f ound in soils. Two soils having the same resistivity may have significantly different corrosion characteri stics, depending on the specific ions available.

The major constituents which accelerate corrosion are bicarbonate ions, chloride ions, sulfate ions, and the pH (acidity) of the soil. Potholing was performed to collect soil samples near the depth of the pipe invert. These soil samples were sent to a Project X Corrosion Engineering laboratory in Murrieta, California to be tested for resistivity and the major corrosive constituents described below.

2.7.1 Resistivity
The in-situ soil resistivity testing per ASTM G57 discussed in Section 2.6 determines the soil resistivity at several different depths at a poin t in time. The minimum soil resistivity provides information about the soil during wet-weather conditions.

Soil resistivity is primarily dependent on the ion and moisture content of the soil. Higher levels of ions in the soil lower the soil resistivity. Additional mois ture decreases the soil resistivity up to the point where the maximum solubility for the dissolved ioni c compounds is achieved. Beyond this point, an increase in moisture increases the resistivity as the ions become more and more diluted. The decrease in soil resistivity is attributed to the pres ence of ions in the “as-received” soil going into solution and providing a less resistive path for current flow.

The following table correlates resistivity values wi th degree of corrosivity. The interpretation of corrosivity correlation to soil resistivity varies somewhat among corrosion engineers. However, Table 2-1 is a generally accepted guide and is based upon corrosivity rankings presented in “Corrosion Basics – An Introduction,” pg. 191 (1984), published by the National Association of Corrosion Engineers (NACE).

Table 2-1. Effect of Resistivity on Soil Corrosivity

High concentrations of bicarbonates tend to decrease soil resistivities. Bicarbonates are not directly aggressive to buried metal, but the lower-resistivity environments can promote corrosion activity. 05/13/2025 C9 706 of 1078

2.7.3 Chloride Ions
Chloride ions found in soils tend to break down otherwise protective surface deposits and can result in corrosion of buried metallic structures and reinforcing steel in concrete structures. Table 2-2 shows the effect of chloride ions on the corrosivit y of the soil. These ranges are generally accepted by the corrosion engineering community.

500 – 1,500 Moderate
100 – 500 Mild
< 100 Negligible

2.7.4 Sulfate Ions
Sulfate ions found in soils can be highly aggressive to the portland cement matrix in concrete by combining chemically with certain constituents of the cement, principally tricalcium aluminate.

Typically, this reaction is accompanied by expansio n and eventual disruption of the concrete matrix, and can result in corrosion of reinforcing steel in concrete structures. High sulfate levels also reduce soil resistivity, which can promote corrosion of buried metallic structures. Table 2-3 shows the effect of sulfate ions on the corrosivit y of the soil. These ranges are ge nerally accepted by the corrosion engineering community.

1,000 – 2,000 Moderate

2.7.5 Soil pH
Acidity, as indicated by the pH value, is another im portant factor of soil wi th respect to corrosivity.

Lower pH (more acidic) will result in a greater de gree of corrosivity with respect to buried metallic and concrete structures. When pH increases above 7.0 (the neutral value), the conditions become increasingly more alkaline. In alkaline environments , steel forms a protective layer on its surface.

This is referred to as passivation. V&A developed Table 2-4, which correlates the effect of pH on the rate of corrosion for buried steel or concrete structures.

3.0 BUENA CREEK PUMP STATION

AND PIPELINES
The BCPS was constructed circa 2002 and has a capacity of 8.8 million gallons per day (mgd). The collection system for the District culminates at this station, and is conveyed to the Buena outfall and the EWA Water Pollution Control Fa cility. V&A conducted a visual assessment, ultrasonic thickness testing, in-situ soil resistivity surveys, and soil sampling at the BCPS and along the downstream pipeline alignments. The visual assessment and ultrasonic thickness testing were conducted on September 10, 2015. Reed Electric & Field Service conducted the pump and motor vibration tests on September 10, 2015. The corrosivity of the so il environment that the pump station excess effluent and force main pipelines are buried in was also assessed. This was done by performing in- situ resistivity testing on January 12, 2016, which included a foreign utility investigation and soil sample analysis. The results of these studies are presented below.

3.1 Dry Well Visual Assessment
The BCPS has five pumps, each rated 4,500 gallons per minute. Pumps 1 and 2 drain the West Wet Well and Pumps 3, 4, and 5 drain the East Wet We ll. The concrete walls, floor, and ceiling of the Pump Room are in good condition. No major spalls or cracks were observed. A few isolated hairline cracks with groundwater leak deposits were seen, predominantly on the south wall. The leachate mineral deposits did not show the brownish staining indicative of reinforcing steel corrosion (Photo 3-1 and Photo 3-2).

V&A Project No. 15-0024 Buena Creek Pump Station and Pipelines 19 The mounting of the pump motors appears to be a significant issue with respect to seismic loading.

The motors and pumps form an inverted-pendulu m arrangement that is only supported by the suction and discharge flanges on each pump (Photo 3-3 and Photo 3-4). It should be noted that the condition assessment did not focus on seismic and structural issues, but this particular issue was apparent based on V&A’s experience with other pump stations.

A variety of minor defects on equipment in th e Pump Room was documented. Minor corrosion staining and hairline cracking was seen on the Pu mp 3 support pedestal (Photo 3-5). Coating failure and corrosion were observed on a discharge piping support at Pump 4 (Photo 3-6). These features indicate minor leaks from above the support pedestals that collect on flat surfaces.

Leakage appears to have occurred at a flange bolt on Pump 3, which is evident from and corrosion staining (Photo 3-9). Wall penetrations of pump su ction piping for Pumps 2, 3, 4, and 5 have leak stains running down the wall. A representative example from Pump 3 is shown in Photo 3-10.

The only active leak in the Pump Room was on th e west wall behind ventilation ducting (Photo 3-11 and Photo 3-12). It may be a supply line to an up stairs bathroom in the Pump Station, and is not associated with the discharge piping and pump systems. A 1-inch diameter copper pipe extending from ceiling to floor on the west wall a few feet south of the active leak is corroded at a tee fitting adjacent to a grounding cable connection (Photo 3- 13). The corroded area was high on the wall and could not be accessed, but appeared to be a connecti on from a slightly larger pipe entering the wall at this point.

3.2 Ultrasonic Thickness Measurements
The ultrasonic thickness data is summarized in Tabl e 3-1. As shown in the table, the wall thickness loss for the ductile iron pipe and fittings, at th e locations that were tested, was mostly within manufacturing tolerances. There were four loca tions that the wall thickness was outside the tolerances, yet by what is considered a mino r degree. The maximum wall thickness loss was calculated to be 19%. However, the wall thicknes s at these locations was outside the manufacturing tolerances by only 0.014 inches.

3.3 Vibration Analysis Results
Vibration testing was performed on Motors and Pumps 1, 2, 4, and 5. Pump 3 was not operational and was not tested. The pumps were run between 78 to 87% speed during the test. System control limitations and high cavitation vibration at lower lo ads dictated that data only be collected at those speeds. General observations of the testing indicate that vibration levels are high on most motor and pump test locations, with many exceeding Internati onal Standards Organization (ISO) and Hydraulic Institute acceptance standards for operating levels. The high readings were directional, primarily in the in-line direction on both the motors and the pu mps. The highest readings on each pump system were typically in the pump lower bearing area. Pr edominant vibration frequency peaks were at two times the running speed. Reed theorizes that the stiffness of the pipe and pump supports may have a significant bearing on the severity of vibratio n. There was no indication of high-frequency mechanical or electrical peaks on any of the test points, indicating that there is minimum hydraulic noise and no apparent VFD issues. A summary of th e testing results is presented in Table 3-2. The full report from Reed Electric is attached is Appendix A.

Table 3-2. Buena Creek Pump Station Vibration Analysis Results MMotor OObservation
Motor/Pump 1 High directional levels in the inline direction from the motor bearings down to the pump bearings. This motor generally had the highest readings at all test points.

Motor/Pump 2 High directional levels in the inline direction from the motor bearings down to the pump bearings, but at lower levels than Pump 1.

Motor/Pump 3 Not tested.

Motor/Pump 4 Pump bearings showed a higher perpendicular relationship than the other pumps. While performing testing, the suction piping support for Pump 4 was found to be loose.

Motor/Pump 5 Generally comparable or lower levels of vibration compared to the other three pumps that were tested.

3.4 In-situ Soil Resistivity Results
Figure 3—1 shows the locations where soil resistivity testing was performed along the excess effluent and force main pipelines. A summary of the in-situ so il resistivity results is presented in Table 3-3.

The complete list of in-situ soil resistivity results is presented in Appendix B. The “resistivity to depth” at a given test site is the resistivity of the soil mass from grade down to the designated depth. Per Section 2.6, resistivities of 10,000 ohm-cm and greater can be considered negligible with regards to corrosion. The resistivities for the layers down to a depth of 7.5 - 10 feet on average are between 2,766 – 2,696 ohm-cm, with locations as low as 287 ohm-cm. This means the majority of the tested soils along the alignment are moderately to highly corrosive, with areas of very highly corrosive conditions. Per the provided record drawings, the de pth of cover for the pipelines ranges from about 5 to 7.5 feet below grade.

V&A Project No. 15-0024 Buena Creek Pump Station and Pipelines 25 Foreign utility investigation revealed a 16-inch co ncrete mortar lined and tape wrapped pipeline owned by Olivenhain Water District on Faraday Av enue (as noted on the brass tag at the cathodic protection test station). Based on the type of test station and the results of the potential testing, the pipeline is cathodically protected with a galvanic system. Current output from galvanic anode beds is low compared to that of typical impressed cu rrent anode beds, so galvanic systems are not considered to be a risk of interference.

Power utilities are primarily underground along the alignment routes evaluated. High voltage power lines cross the pipeline alignments on Melrose Dr ive between Sycamore Avenue and Mountain Pass Circle. High voltage alternating current can be reas on for concern when power lines parallel buried pipelines for long distances. This short crossing is noted, but is not of concern.

3.5 Soil Sample Analysis Results
The locations of the potholing where soil samples were collected are shown in Figure 3—2. Table 3-4 presents a summary of the laboratory analysis resu lts. Based on the guidelines in Section 2.7 the three soil samples were high to moderately corrosi ve. Site 3 is the most corrosive considering the high chloride concentration.

3.6 Conclusions
Based on the results of the condition assessment, V&A presents the following conclusions:

1. The evaluated concrete surfaces are in good condition, rated VANDA Level 1.

2. Metal surfaces are in good condition with th e majority of the coating (about 90%) intact.

There is some copper piping that is significantly corroded (VANDA Level 3).

3. At most of the testing locations, the DIP is in good condition and is rated VANDA Level 1.

There were a few locations that showed wall thickness outside the manufacturing tolerances by what is considered a minor degree. No significant exterior corrosion or leaks were observed on the rest of the piping in the dr y well, which was outside the ultrasonic testing areas.

4. The inverted pendulum arrangement of the motor and pumps appears to be a significant issue with respect to seismic loading. However, seismic/structural analysis was not part of the project scope of work.

5. Vibration levels are high on most motor and pu mp test locations, with many exceeding ISO and Hydraulic Institute acceptance standards for operating levels.

6. The buried excess effluent and force main DI P are within a moderately to very highly corrosive soil environment.

3.7 Recommendations
Based on the conclusions of the condition assessment, V&A presents the following recommendations:

1. The evidence of groundwater infiltration on the concrete walls and the corrosive soil environment around the pump station warrant additional testing in the concrete pump room.

Testing to be considered includes:
a. Concrete core analysis to identify corrosion stimulants and concrete characteristics b. Determining placement of reinforcing steel
c. Identify corrosion potential on reinforcing steel and visually verify condition

2. Seal points of infiltration at the construction joints. It is recommended this be done after performing additional concrete testing to de termine the appropriate repair/rehabilitation approach.

3. Repair damaged coating on mechanical equipment and piping as needed. Prepare surfaces to remain per SSPC SP 2 to 3. Coat with a 100% solids epoxy or polyurethane coating system, such as Carboline Carboguard 890, PPG Amercoat Amerlock 400, or Tnemec Series N69 at 2 to 3 mils dry film thickness.

4. Clean the surfaces of the copper piping and determine if the replacement of copper piping is warranted.

5. Evaluate the seismic vulnerability of the motor and pump arrangement.

6. Reed Electric recommended the following actions for the pumps and motors based on the vibration analysis results:
a. #3 Motor & Pump: This unit had VFD drive or other electrical issues during the test. It will need to be scheduled for a retest when feasible.
b. The evidence of high vibration on all motor and pump structures warrants a full structural mode shape analysis, to allow proper definition of any resonance issues as they relate to structure, and should result in effective recommendations to adjust or change the supports, etc., to reduce the effect.
c. #1 Motor & Pump – The extremely high levels on this unit warrant prioritized scheduling of detailed analysis and correction. In the meantime, the stiffness of the pump supports should be inspected for rigidity (see typical pump supports, Figures 4 & 5).
d. #2 Motor & Pump – The high levels on this unit warrant scheduling of detailed analysis and correction. In the meantime, the stiffness of the pump supports should be inspected for rigidity.
e. #4 Pump – This units’ suction piping support was found loose, and should be adjusted.

7. Consider cathodic protection for buried metal pipi ng if it is to remain in service for the next 20 years. If a new pipeline is to be installed, alternative materials to metal or concrete, such as plastic, should be considered.

4.0 BUENA VISTA PUMP STATION
The BVPS is a 23.1-mgd pump station originally constructed circa 1986. The pumps and piping were rebuilt circa 1994. The force main within the pump station site was reconfigured circa 2013, including the addition of two new flow meter vaults and surge tanks. V&A conducted a visual assessment and ultrasonic thickness testing at the pump station on September 9, 2015. Reed Electric & Field Service conducted the pump and motor vibration tests on September 10, 2015. The findings of these studies are presented below.

4.1 Dry Well Visual Assessment
The interior concrete surfaces of the dry well (lower level pump room) generally appeared to be in good condition and exhibited minimal evidence of degradation (Photo 4-1). However, there were some notable observations and minor, isolated defects, such as the following:

1. There were several isolated areas where there was evidence of groundwater seeping in through the exterior walls of the dry well. So me of these areas appeared to have been abandoned penetrations that have been patc hed. Some locations showed rust-colored staining (Photo 4-2).

2. At a few other locations, such as the discharge manifold penetration from Pumps 4 and 5, there was apparently some type of injection foam or epoxy that had dripped down the wall, probably during construction (Photo 4-3). No evidence of infiltration was observed though.

3. The mortar below the pump baseplates has cracked or spalled in some locations, particularly on Pumps 4 and 5 (Photo 4-4).

The coatings on the pumps, piping, and valves we re generally intact, but again there were some notable observations and defects, such as the following:

4. There were numerous small chips in the co ating in some areas, particularly on the components at lower elevations, such as the pump volutes, pump stands, valves, and pipe supports (Photo 4-5).

V&A Project No. 15-0024 Buena Vista Pump Station 30

5. The coating has failed around the penetration of the check valve lever shafts (Photo 4-6).

This is probably due to leakage through the packing. There was minor surface corrosion of the valve body where the coating has failed.

6. The underside of the rectangular suction lines did not appear to be coated thoroughly at the wall penetrations from the wet well.

Photo 4-5. Typical coating condition on
piping at lower levels. Numerous small chips

Photo 4-6. Coating failure and apparent
leakage on check valves.

In general, the exterior of the dry well piping was in good condition, along with the coatings as noted above (Photo 4-7). The pipe supports also appeared to be in good condition. Notable observations and defects included the following:

7. One pipe spool on the discharge header from Pumps 1 and 2 had a direct-threaded tap at the top of the pipe, with coating failure and moderate external corrosion surrounding the tap (Photo 4-8). It appears that the threaded ta p may leak. This spool was also an isolated location of internal wall thickness loss, as note d below in Section 4.3. It may be that the corrosion was caused by installation of the ta p having damaged both the coating and lining on this spool.

8. Most of the flanged joints did not exhibit sign s of leakage, but there were stains emanating from the suction flange on Pump 4 (Photo 4- 9). There was also evidence of minor leakage from some of the check valve covers (Photo 4-10).

4.2 Meter Vault Visual Assessments
The two meter vaults showed moderate to extens ive groundwater seepage at several locations at various heights on the walls. Most of these locations were characterized by rust-colored staining. The floor of each vault was wet during the evaluation, wi th a slight amount of puddling in some areas.

Examples of the groundwater infiltration are show n in Photo 4-13 to Photo 4-16. This water may be brackish due to proximity to a nearby creek and lagoon. The chloride content in brackish water would tend to promote corrosion of the reinforcing steel in the walls, as well as items inside the vaults that may be immersed. It should be noted that the meter vaults are only a few years old.

The coating on the 24-inch DIP force main in the mete r vaults is peeling off the pipe at the concrete wall penetrations. There is surface corrosion on the DIP, particularly in the north meter vault (Photo 4-17). This coating failure and corrosion appears to be related to groundwater intrusion at the pipe penetrations. The wall penetration details shown on the “as built” drawings for the “Buena Vista Lift Station Force Main (VC-4) – Contract No. 55081” diff ered from the penetrations observed on-site.

The drawings show a sleeve with a waterstop ring embedded in the concrete, with mechanical expanding rubber seals (i.e., Link-Seals) and a sealant sealing the gap between the pipe and the sleeve. Instead the DIP force mains appear to have been directly embedded in the concrete walls and there may not be a waterstop ring. This woul d tend to explain the evidence of groundwater intrusion at the pipe penetrations.

The flow meter within each vault is equipped with a bare copper ground cable that attaches to a grounding ring at one of the meter flanges. The copper cables show a green copper oxide product on the surface, but generally appear to be intact. Th ere is greater and apparently ongoing oxidation at some of the connectors for the copper cables. Wher e the cables connect to the meter flanges, the moisture is dripping on the adjacent pipe flange and causing apparent coating failure and surface corrosion (Photo 4-18). In comparison with the corrosion observed at the connectors, the green oxide product on the cable itself does no t appear to be a significant concern. The ground cable is also zip- tied to the outside of another conduit and appears to be damaging the coating on the conduit.

Other than the isolated defects noted above, the DIP and flow meter, as well as their coatings, within each vault appear to be in good condition. However, the hold-down rods for the pipe supports in each vault may eventually cause coating failure and corros ion of the pipe at that location. The hold-down rods were applied directly over the coated DIP surface without any form of galvanic or vibration isolation (such as a rubber pad) in between.

The pipe support saddle in each vault has what ap pears to be a square galvanized steel baseplate bolted to a small concrete mortar pad. Despite th e galvanizing, the edges of the baseplate in each vault show evidence of corrosion (Photo 4-19). Th e corrosion may be due to water standing within the vaults, particularly if it is brackish water.

The plug valve downstream from each flow meter rests on a concrete support. The valve support in the north meter vault exhibits isolated spalling and corrosion of the reinforcing steel, probably due to insufficient depth of concrete cover (Photo 4-20).

The north meter vault drains to the south meter vault, which has a sump pump. The sump pump is connected to the discharge piping by a short length of rubber hose with cam-lock fittings at either end. The lower fitting is severely corroded or encrusted (Photo 4-21), while the upper fitting shows surface corrosion. The fittings appear to be aluminum, which is not corrosion-resistant in an environment with brackish water or seawater. The pump is plugged into a standard 120-volt outlet higher on the vault wall. The outlet box has surface corrosion along its lower edge and may not be watertight (Photo 4-22).

4.3 Ultrasonic Thickness Measurements
The ultrasonic thickness data is summarized in Tabl e 4-1. As shown in the table, the wall thickness loss for the DIP, at the locations that were tested , was within manufacturing tolerances, except at one location on the header downstream of Pumps 1 and 2. At this location, there appears to be a significant thickness loss of 0.167 inches, or 37% of the assumed nominal thickness. This spool also exhibited localized external corrosion, as noted above in Photo 4-8. The maximum wall thickness loss for the fabricated, rectangular steel suction lines was 9%, which is considered negligible considering the tolerances that may have been applicable (steel pipe made to ASTM standards often has a thickness tolerance of −12.5%).

4.4 Vibration Analysis Results
Vibration testing was performed on Motors and Pumps 1, 2, 4 and 5. There is no Motor or Pump 3 at the BVPS. The pumps were run at approximatel y 65% and near 100% speed. System control limitations only allowed data to be collected at ap proximately 65% speed on many of the pump test points. General observations of the testing indicate that vibration levels are reasonable on most motor and pump test locations, with the majority meeting ISO and Hydraulic Institute acceptance standards for operating levels. The highest readings were noted in the perpendicular direction on both the motors and the pumps. This appears to be due to a residual resonance issue. There was no indication of high-frequency mechanical or electric al peaks on any of the test points, pointing to minimum hydraulic noise and no apparent VFD issues. Predominant vibration frequency peaks were two, three, and six times running speed, felt primar ily to be the area of re sonant response on these structures. Reed believes the stiffening beams abov e the pumps to be related to reducing vibration.

However, it also appears likely that they were in stalled for seismic considerations. A summary of the testing results is presented in Table 4-2. The full report from Reed Electric is attached in Appendix A.

4.5 Conclusions
Based on the results of the condition assessment, V&A presents the following conclusions:

1. In general, the concrete interior surfaces of the dry well were in good condition (VANDA Level 1). There were, however, some isolated areas of groundwater infiltration, some with staining indicating possible corrosion of the reinforcing steel. The grout pads under the pump bases showed deterioration at the edges in some cases.

2. The coating on the piping was generally in go od condition at higher elevations, with numerous chips and other defects in the coating at lower elevations. Generally, there was minor surface corrosion where the coating was damaged. There was also one spool downstream of Pumps 1 and 2 that exhibited moderate external corrosion.

3. At most of the ultrasonic thickness testing location s, the dry well piping is in good condition, but there was one location on the header downstream of Pumps 1 and 2 that exhibited a significant thickness loss of 37%. This location also exhibited external corrosion. It is possible, though considered unlikely, that the pipe at this location was manufactured thinner than required by AWWA standards. No signific ant exterior corrosion or leaks were observed on the rest of the piping in the dry well, which was outside the ultrasonic testing areas.

4. The bathroom drain piping and ventilation ducting exhibited various moderate-severity defects.

5. The meter vaults show moderate to extensive groundwater infiltration, with staining that indicates possible corrosion of the reinforcing steel. The vaults are only a few years old. The extent of staining may indicate that the water leaking into the vaults is brackish, which would promote corrosion.

6. The piping, pipe supports, sump pump fittings, and electrical items within the meter vaults also showed various defects that appear to be related to the grou ndwater infiltration, particularly if it is brackish.

7. Reed Electric identified several minor- to moderate-severity vibration issues and recommended that these be addressed during the next planned outage. 05/13/2025 C9 729 of 1078

4.6 Recommendations
Based on the conclusions of the condition assessment, V&A presents the following recommendations:

1. Monitor areas of infiltration within the dry we ll for increased evidence of infiltration or corrosion staining. Consider further evaluation of the concrete and reinforcing steel in areas where there is corrosion staining. Testing to be considered includes:
o Concrete core analysis to identify corrosion stimulants and concrete characteristics o Determining placement of reinforcing steel
o Identify corrosion potential on reinforcing steel and visually verify condition

2. Consider repairing the grout pads under the pump bases.

3. Recoat the exterior of the piping, at least at lower elevations, to prevent further corrosion.

The lower elevations are subject to more water splashing and dripping from operations and maintenance activities, which exacerbates any minor coating defects that may be present.

Prepare surfaces to remain per SSPC SP 2 to 3. Coat with a 100% solids epoxy or polyurethane coating system, such as Carbol ine Carboguard 890, PPG Amercoat Amerlock 400, or Tnemec Series N69 at 2 to 3 mils dry film thickness.

4. Calculate the minimum required thickness for the piping based on pressure, loading, etc.

Compare the minimum required thickness against the measured thicknesses in this report to determine the amount of further wall loss that can be tolerated, if any, before the integrity of the piping is impaired. With the results of th is analysis in mind, consider conducting the following activities to address corrosion and integrity of the dry well piping:
o Address the corrosion on the spool downs tream of Pumps 1 and 2. Replacing the spool is probably the most cost-effective option. When the piping is shut down and drained for this activity, consider using this opportunity to evaluate the interior of the remaining piping. This could be done using closed-circuit television (CCTV). This would provide further insight on the lining condition and corrosion inside the piping, which is expected to be localized.
o Ensure that there is a contingency plan and materials available in case of a piping leak or failure. The data indicated that there may be isolated areas of corrosion.

Consider the impact of a failure or leak. If the impact to operations is greater, the preparations should be more comprehensive, and further evaluation of the piping should be conducted.

5. Repair the bathroom drain piping and ventilation ducting connections.

6. Perform testing to quantify the extent of degr adation of the concrete and reinforcement in the two meter vaults. Testing to consider is similar to that recommended for the dry well.

Sample the water entering the vaults for resistivity and chloride content.

7. Address the electrical connections within the meter vaults (meter ground cables and power for sump pump). Replace corroded connectors with corrosion-resistant materials and take precautions for galvanic corrosion between dissimilar metals.

8. Replace the cam-lock fittings for the sump pump in the south meter vault. 05/13/2025 C9 730 of 1078

Pump Station Condition Assessments Draft Report

V&A Project No. 15-0024 Buena Vista Pump Station 39

9. Assuming that the groundwater entering the meter vaults is brackish (see sampling recommendation above), use materials and coat ings suitable for a marine environment for all items within the vaults.

10. Consider whether the groundwater may also be aggressive to the buried DIP force mains within the pump station site, review the construction details for the force mains to determine whether adequate corrosion protection was provided for the buried pipe. Consider conducting field evaluations to determine the co rrosivity of the soil and/or the condition of the buried DIP.

11. Reed Electric recommended the following actions for the pumps and motors based on the vibration analysis results:
o The evidence of historical vibration issues based on the need for dampeners on all motor and pump structures necessitates the frequent periodic monitoring of the vibration, to assure that the stiffness of the arms does not change significantly with time or maintenance.
o #4 Motor – If a motor inspection is forecast , this would be the prioritized unit for mechanical disassembly and inspection.
o #5 Motor & Pump – If a unit inspection is fo recast, this would be the prioritized unit for motor bearing inspection and pump impeller inspection. o #2 Pump – The pump dampener structures and piping supports should be inspected for rigidity.

5.0 RACEWAY PUMP STATION
The RPS was constructed circa 1988 and is a 1.9 mgd pump station. The station was replaced in 2007. V&A conducted a visual assessment and ultraso nic thickness testing at the pump station on September 11, 2015. The findings of these studies are presented below.

5.1 Visual Assessment
The majority of exterior surface of pump piping ha s no signs of corrosion. The exterior coating is in good condition. There is corrosion staining and cr acked coating on conduits near the pump piping.

The concrete reservoir has cracking and staining in dicating possible infiltration or exfiltration at some of those areas. The concrete at the guard rail connections is cracked and damaged by spalling.

The embedded guardrail post was not coated with a coal tar and PVC sleeve in order to isolate it from the concrete. There is no horizontal reinforcing steel on the outer wall of the curb which also allowed the corroding railing to cr ack the concrete. Examples of the defects are shown in Photo 5-1 through Photo 5-6.

5.2 Ultrasonic Thickness Measurements
The ultrasonic thickness data is summarized in Tabl e 5-1. As shown in the table, the wall thickness loss for the DIP and fittings, at the locations that were tested, was mostly within manufacturing tolerances. At three locations the wall thickness was outside the tolerances by what is considered a minor degree. The maximum wall thickness loss was calculated to be 18% for the DIP and 21% for the fittings. However, at these locations, the wall thickness was outside the manufacturing tolerances by only 0.028 inches or less.

5.3 Conclusions
Based on the results of the condition assessment, V&A presents the following conclusions:

1. There is potential infiltration/exfiltration at cr acks in the concrete reservoir. The concrete surface is in good condition though (VANDA Level 1). The concrete has spalled at the base of the guardrail around the concrete reservoir due to a lack of insulation between the aluminum and concrete material.

2. The coating on the electrical box supports has failed and the concrete is damaged at the base. There is corrosion staining on the electrical box and conduits.

3. The surface of the piping is in good condition, with the majority of the coating (about 90%) intact. The coating on the flange near the Pump 3 discharge pipe has failed though, leading to the exposed metal surface to have moderate corrosion (VANDA Level 3).

4. At most of the testing locations, the pipe and fittings are in good condition. There were a few locations that showed wall thickness outsid e the manufacturing tolerances by what is considered a minor degree. The pipe spools that showed this increased wall thickness loss were assumed to have been manufactured th icker than Class 53 (minimum required for flanged DIP per AWWA C115). Overall, while there may have been a minor thickness loss at a few locations, it does not appear to have been to a significant degree. The piping and fittings are rated a VANDA Level 1.

5.4 Recommendations
Based on the conclusions of the condition assessment, V&A presents the following recommendations:

1. Seal points of infiltration/exfiltration within the concrete reservoir

2. Install a grout or sealant at the base of the aluminum posts and slope it so that water runoff is allowed to flow away from the embedded section.

3. Replace corroded conduits.

4. Recoat or replace the corroded metal flange near the Pump 3 discharge pipe.

5. Recoat piping and electrical equipment as ne eded. Prepare surfaces to remain per SSPC SP 2 to 3. Coat with a 100% solids epoxy or po lyurethane coating system, such as Carboline Carboguard 890, PPG Amercoat Amerlock 400, or Tnemec Series N69 at 2 to 3 mils dry film thickness.

1 BUENA CREEK SEWAGE PUMPS VIBRATION ANALYSIS

FOR CONDITION ASSESSMENT

TEST SETUP:

1. Instrumentation: An ADASH 4-channel data recorder and analyzer was utilized along with three magnetic- mount accelerometers and a laser speed tachometer (see typical Motor monitoring setup, Figure 1).

2. Test Locations: The sensors were mounted on the Motor Upper, Motor Lower, Pump Upper, and Pump Lower bearings, in the Inline, Crossline (Perpendicular), and axial directions for each of the tests (see test layout schematic, Figure 2).

3. Test Conditions: The units were run between 78-87% load under normal operating mode. System control limitations and high cavitation vibration at lower loads dictated that data only be collected at that condition. The following data was recorded for each test:
a. overall velocity and displacement vibration
b. velocity spectrum plots
c. filtered amplitude/phase measurements (where the tach was available) See a table of overall velocity levels for each test point in Figure 6, and charts showing comparative levels on Pages 11 -14.

OBSERVATIONS:

4. General:
a. Vibration levels are high on most motor and pump test locations, with many exceeding ISO and Hydraulic Institute acceptance standards for operating levels. b. In general, the high readings were very directional, primarily in the In-Line (Parallel) direction on both the Motors and Pumps. The highest readings on each pump system were typically in the Pump Lower bearing area. This was felt to be due to a residual system resonance issue, which appears to be sensitive to piping support stiffness (see and typical motor-pump layout, Figure 3). c. In general, there was no indication of high-frequency mechanical or electrical peaks on any of the test points, pointing to minimum hydraulic noise, and no apparent VFD issues. d. Predominant frequencies peaks of vibration was 2X running speed, felt primarily to be the area of resonant response on these structures.

5. Specific Units:
a. #1 Motor-Pump – This unit showed high directional levels in the inline direction from the motor bearings down to the pump bearings. The predominant frequency of vibration was the 2X running speed peak (see all #1 bearing inline spectrums Figure 7). This motor generally had the highest readings at all test points (see level comparison charts, Pages 11– 14). b. #2 Motor-Pump – This unit showed similar high directional levels in the inline direction from the motor bearings down to the pump bearings, though at lower levels, with the same predominant frequency (see all #2 bearing inline spectrums Figure 8, and level comparison charts, Pages 11– 14). c. #4 Pump – the pump bearings showed a higher perpendicular relationship than the other pumps. 05/13/2025 C9 739 of 1078

2 RECOMMENDATIONS:

1. #3 Motor & Pump: This unit had VFD drive or other electrical issues during the test. It will need to be scheduled for a retest when feasible.

2. General Monitoring: The evidence of high vibration on all motor and pump structures warrants a full structural mode shape analysis, to allow proper definition of any resonance issues as they relate to structure, and should result in effective recommendations to adjust or change the supports, etc., to reduce the effect.

3. #1 Motor & Pump – The extremely high levels on this unit warrant prioritized scheduling of detailed analysis and correction. In the meantime, the stiffness of the pump supports should be inspected for rigidity (see typical pump supports, Figures 4 & 5).

4. #2 Motor & Pump – The high levels on this unit warrant scheduling of detailed analysis and correction. In the meantime, the stiffness of the pump supports should be inspected for rigidity.

5. #4 Pump – This units’ suction piping support was found loose, and should be adjusted.

1 BUENA VISTA & SEWAGE PUMPS VIBRATION ANALYSIS

FOR CONDITION ASSESSMENT

TEST SETUP:

1. Instrumentation: An ADASH 4-channel data recorder and analyzer was utilized along with three magnetic- mount accelerometers and a laser speed tachometer (see typical Pump monitoring setup, Figure 1).

3. Test Conditions: The units were run at ~65% and near 100% load. System control limitations only allowed data to be collected at ~65% load on many of the pump test points. The following data was recorded for each test:
a. overall velocity and displacement vibration
b. velocity spectrum plots
c. filtered amplitude/phase measurements (where the tach was available) See a table of overall velocity levels for each test point in Figure 5, and charts showing comparative levels on Pages 12 – 15.

OBSERVATIONS:

4. General:
a. Vibration levels are reasonable on most motor and pump test locations, with the majority meeting ISO and Hydraulic Institute acceptance standards for operating levels. b. In general, the highest readings were noted in the Cross Line (Perpendicular) direction on both the Motors and Pumps. This was felt to be due to a residual system resonance issue, which was likely the reason for the stiffening beams on both the Motor and Pump structures (see and typical motor and pump layouts, 3 & 4).
c. In general, there was no indication of high-frequency mechanical or electrical peaks on any of the test points, pointing to minimum hydraulic noise, and no apparent VFD issues. d. Predominant frequencies peaks of vibration were 2X, 3X, and 6X running speed, felt primarily to be the area of resonant response on these structures.

5. Specific Units:
a. #4 Motor – This motor showed some unusual multiple harmonics of running speed on the Motor Upper bearing (see Motor Upper Perpendicular spectrum Figure 6). This motor generally had the highest readings at all test points (see level comparison charts, Pages 12 – 15). b. #5 Motor & Pump – This motor has a high 6X peak on the Motor Upper bearings, with some high- frequency peaks indicative of bearing looseness (see Motor Upper Perpendicular spectrum Figure 7).

Additionally, the Pump Upper bearing shows some indication of cavitation noise, and is the only pump in the plant to exhibit this, though only at low load (see Pump Upper Perpendicular spectrum, Figure 8). c. #2 Pump – the pump Upper bearing has a high 4X peak at 65% load. Most of this pump’s test points are higher than the other pumps (see Pump Perpendicular spectrum, Figure 9). 05/13/2025 C9 753 of 1078

2 RECOMMENDATIONS:

1. General Monitoring: The evidence of historical vibration issues based on the need for dampeners on all motor and pump structures necessitates the frequent periodic monitoring of the vibration, to assure that the stiffness of the arms does not change significantly with time or maintenance.

2. #4 Motor – If a motor inspection is forecast, this would be the prioritized unit for mechanical disassembly and inspection.

3. #5 Motor & Pump – If a unit inspection is forecast, this would be the prioritized unit for motor bearing inspection and pump impeller inspection.

4. #2 Pump – The pump dampener structures and piping supports should be inspected for rigidity.

DATA

1. A summary table of overall velocity levels for each position at each test load is shown in Figure 5.

2. Charts showing comparison levels for each position at the different loads is shown on Pages 12 - 15.

3. Spectrum Waterfall plots for each position are available if requested.

Vista, CA 92084
Subject: City of Vista - Grinder Replacement at Raceway Pumping Station Dear Mr. Pedroza:

This letter report highlights Carollo's investigation into installation of new grinders at the City of Vista's (City) Raceway Pump Station (RWPS).

BACKGROUND
The RWPS is a sewage lift station with a design capacity of 2.1 million gallons per day (mgd).

As wastewater enters the RWPS, it passes through a sewage grinder prior to entering the pump station wet well. The grinder consists of two shafts of cutters that spin in opposite directions.

The cutters shred large debris and rags to prevent "pump ragging," which occurs when rags wrap around the pump impellers. Pump ragging can damage the pumps, motors and variable frequency drives (VFD) downstream. If the grinder is offline, or removed for servicing, the flow is diverted to a PVC pipe rack that requires labor-intensive manual cleaning by Encina staff.

Under current operations, the Moyno grinder has been out of service for over six months and is currently having a complete motor rebuild. The pipe rack allows rags to pass through intact and has resulted in at least one instance of a pump ragging. The ragging was sever enough to result in significant damage to the pump VFD and required replacement. Replacement of the existing set-up with a grinder in each channel is desired.

DESIGN CRITERIA
Each grinder should be able to match the existing pump station capacity so that redundancy is maintained for each of the influent channels. The existing channels are 4.25 feet (ft.) wide by

1.9 ft. long with a maximum water depth of 2.47 ft. The channels are separated by a concrete wall and a weir that diverts flow to the bar screen (or second grinder) channel as needed.

Installation of mechanical equipment in each channel does increase the risk of a pump station overflow if both devices were to fail. New grinders should be capable of motor submersion to allow an overflow bypass in the event of failure.

ALTERNATIVES
Two JWC Environmental Open Channel Grinders have been evaluated for use at RWPS, the 30005 Series Wipes Ready Muffin Monster and the Wipes Ready CMD Series Channel 05/13/2025 C9 825 of 1078
