SUBJECT: Discuss Proposed Revised General Budget for Fiscal Year 2020-

Executive Summary

The purpose of this report is to discuss proposed revised general budget for Fiscal Year

2020-21 and authorize the General Manager to submit it to Member Agencies for

approval.

Fiscal Impact

The impact to the member agency assessments is given below:

The recommendations in the proposed budget comply with SAM Strategic Plan Goal 3:

“Consider long-term costs and ensure that finances are stable and understandable by

the board, member agencies, and the public.”


On April 27th, the Board authorized the General Manager to submit to the member

agencies for approval the preliminary general budget for the fiscal year 2020-21 in the

form presented to the Board that evening. However, the member agency managers met

on April 28th and determined that the overhead charge of $180,000 should be removed

from the draft Collection budget (as an expense item) and from the general budget

(where it appears as a revenue item). This change reduces the expenditures in the

Collection budget by $180,000 and increases the assessments to be paid by the

member agencies under the general budget by the same amount, allocated as follows:

As the above chart shows the revised 2020-21 preliminary budget is still below the

2019-20 adopted budget by $107,365 or 1.44% vs $287,366 or 3.9% approved by the

Board on 4/27.

If the Board approves the removal of the overhead revenue item from the general

budget and the revised amounts of the member agencies’ respective assessments, they

will be set forth in the general budget submitted to the member agencies for their

approval.


Staff recommends the Board authorize the General Manager to submit the proposed

SUBJECT: Discuss Proposed Contract Collection Services Budget for FY

2020/21 and Authorize the General Manager to submit it to the

Participating Agencies for approval

Executive Summary

The purpose of the report is to discuss the contract collection services budget for FY

2020/21 and authorize the General Manager to submit it to the Participating Agencies

for approval

Fiscal Impact

The total cost to provide the Member Agency requested services for Fiscal Year

2020/21 is $672,373. This amount is payable to SAM as contract service fees from the

served agencies. This is an overall decrease in fees of $144,265 attributed to collection

systems contract maintenance for the agencies. The following table reflects the history

of fees for each agency for the past three years, the current year, and the upcoming

year.

Total $915,839 $793,961 $923,444 $816,638 $672,373 - $ 144,265 - 17%

The proposed budget is impacted mostly by the decision to remove $180,000 Overhead Charges. Upon review of the process with staff and accounting/budgeting consultants it was determine that the recent

25


Page 2


practice of allocating a portion of SAM Administrative Overhead costs to the Collection Budget should cease as it is more transparent to have those costs entirely attributed to the SAM General Budget Administrative costs. This decision is consistent with SAM’s goal of simplifying the budget process going forward. There is an increased cost to the proposed budget of approximately $46,000 which is almost entirely

attributable to costs incurred over the last year due to actual levels of “Hot Spot” cleaning required to

prevent pipeline plugging and expected to continue into the future.. The removal of the misapplied funds plus the added cost of Hot Spot cleaning requirements results in a net reduction of $144,265.00 compared

to last year’s approved budget for collections system maintenance services.

The pie-chart below details the allocation of the proposed budget for each Member Agency.


The recommendations in the proposed budget comply with SAM Strategic Plan Goal

5.6: “SAM is committed to providing quality collection system maintenance service for

the Coastside. It will seek to offer the type of agile and responsive service and cost that

wins that business. However, SAM resources should not be used to backstop collection

service without appropriate compensation and pre-planning so it does not impact SAM

operations and maintenance.”

SAM has provided collection system maintenance services to its member agencies

since 1988. The scope of services has changed over the years to meet regulatory

requirements and individual needs of the Member Agencies. While the cost allocation

methodology has changed over the years, the Member Agency Managers along with

the SAM Manager and consultants have worked together to develop a method of

allocation, beginning this year and hoped to be used in the future, based on the needed

services of each agency. The cost allocation presented reflect that method and those

needs.

Beginning July 1, 2020 the minimum service level provided by SAM will entail cleaning

at least fifty percent (50%) of the collection system’s pipelines, cleaning of designated

Hot Spots per an agreed upon schedule, provide lift station services as defined, provide

emergency response throughout the year and performance of reporting and planning as

needed to ensure all needs of each Member Agency’s service area collection system is

met.

The proposed budget includes obligations for wages and benefits as stipulated in

employment and bargaining contracts, utilities, fuel, rental equipment, insurance and

other expenses needed to perform all needed and required services.

The performance of collection system maintenance is a very staff intensive activity

and, thereby, most costs (76%) as shown above are for wages and benefits for

personnel to perform the work. Other significant costs are insurance provided for the

Member Agencies related to their collection systems and rental equipment needed as

support for the work. All other costs combined are less than 5% of the total overall

budget.


Staff recommends that the Board of Directors authorize the General Manager to submit

the Contract Collection Services Budget for Fiscal Year 2020/21 to the participating

agencies for approval.

Technical Memorandum To: Kishen Prathivadi, PE

From: Tim Monahan, PE

Date: May 7, 2020

Re: DRAFT - Princeton Force Main Condition Assessment

Background Princeton Force Main (PFM) is part of the Intertie Pipeline System (IPS) that is owned and operated by the

Sewer Authority of Mid-Coastside (SAM). The IPS conveys wastewater collected in Montara, Moss Beach,

Princeton-by-the-Sea, and El Granada to SAM’s wastewater treatment plant (WWTP). Princeton Force

Main starts at the Princeton Pump Station and discharges into Montara Force Main (Figure 1). PFM is an

8-inch-diameter ductile iron pipe with polyethylene liner installed in 1979. Its total length is approximately

4,200 linear feet (LF). Two air release valves are located along the force main.

DRAFT Princeton Force Main Condition Assessment Technical Memorandum May, 2020 Page 2 of 14

In 2017, a series of breaks happened on Granada Force Main (GFM), which is also part of the IPS system.

These breaks resulted in reportable Sanitary Sewer Overflows (SSOs). Due to these breaks, SAM initiated

a thorough condition assessment on the rest of the force mains in the IPS system. Princeton Force Main

was scheduled to be assessed in 2019 - 2020, and Montara Force Main is scheduled to be assessed in 2020

- 2021. The purposes of the condition assessment is to determine the remaining useful life on the

pipelines and inform any replacement/rehabilitation needs.

Methodology The key to a successful condition assessment is to determine the pipe wall thickness as accurately as

possible. This involves removing a segment of the pipe or obtaining samples/coupons to be analyzed. This

requires that the pipeline to be taken out of service and drained. Due to the limited size of the Princeton

PS wet well and volume of wastewater contained in the PFM, this was not possible, therefore non-

destructive testing (NDT) methods were used. An Ultrasonic thickness (UT) gauge is typically used for

determine the thickness of the pipe wall. The limitation of using the UT gauge is that it only takes point

measurements and the overall pipe condition needs to be deduced from a limited number of readings.

Electromagnetic scanning is another NDT method that can be used in conjunction with the UT gauge. The

advantage of electromagnetic scanning is that it can scan a wider area and provide a more comprehensive

assessment of the pipeline’s condition. Both technologies require excavating to the force main, but they

allowed the PFM and Princeton Pump Station to remain in service.

The condition assessment was performed in two stages. is the first was a desktop assessment, including

hydraulic modeling of the Force Main using Bentley WaterCAD and researching soil conditions in the

pipeline’s surrounding area. The second stage involved excavating and exposing the pipeline at 3 locations

as shown in Figure 2., The test pits allowed SAM’s team of engineers to sample the soil and groundwater

surrounding the pipeline, perform visual inspection of the exterior, and perform determine the pipe’s wall

thickness by UT and electromagnetic scanning.

PFM Condition Assessment Team SAM retained SRT Consultants (SRT) to perform the condition assessment of the PFM. SRT assembled a

team of engineers, scientist, industry professionals, and a general contractor to conduct the assessment.

BAGG Engineers of San Jose, CA provided technical assistance, conducted soil and groundwater sampling

and analysis, and UT testing of the pipeline. Pipeline Inspection and Condition Analysis Corporation (PICA)

provided technicians and engineers for the electromagnetic scanning and pipe wall thickness assessment.

Andreini Brothers of Half Moon Bay, CA served as the general contractor and excavated the test pits,

install shoring, backfilled, and restored the pavement upon completion. The Ductile Iron Pipe Research

Association (DIPRA) was engaged to perform field observations and to provide expert opinions on pipe’s

condition. SAM conducted a kickoff meeting and site visit with all parties in December 2019 to introduce

the project background and facilitate communication and coordination. The actual field work was

performed in March 2020.

Field Testing The three excavation/test pit locations were chosen at the beginning, end, and middle of the force main

alignment. The excavations were conducted on March 9, 10, and 11, 2020. Each test pit was

approximately 10 feet long, 5 feet wide, and 7 feet deep. The force main in these pits was fully exposed

to allow the electromagnetic bracelet probe to scan the entire circumference of the pipe.

The electromagnetic scanning bracelet (Figure 3) was used at each test pit location. This device uses

“through transmission” to detect both inner and outer wall loss and other defects. Each bracelet probe

scan covers a 9-inch swath of the pipe wall in the axial direction. Multiple scans were performed on the

same pipe segment to achieve a 360-degree image. The readings generated by the bracelet probe were

calibrated by simultaneously taking UT gauge readings.

Results and Discussion The following sections present the results of the hydraulic study and field condition assessment of the

PFM.

Desktop Assessments Results A hydraulic model was developed in WaterCAD to simulate pressure and flow in the 8 inch diameter force

main under normal operating conditions. Although WaterCAD is typically used for water distribution

system modeling, it is suitable for this application since the force main is a pressurized pipe. A friction loss

factor of 120 was used to calculate headloss in the Hazen-Williams equation in order to simulate aging

ductile iron. The elevation of the force main is based on the record drawings, and the ground elevation

was calibrated using GIS data from San Mateo County. The discharge line pressure in the Montara Force

Main was estimated based on the average reading of a pressure gauge installed on the Princeton Force

Main near its connection to the Montara FM at Highway 1. The average pressure reading was

approximately 15 psi.

The modeling results show that during normal operation, the PFM is fully pressurized because its elevation

gradually increases from the pump station to the discharge point. There are only a few high points where

it crosses the Dennison Creek and near its discharge point.

A desktop assessment of the local geology and seismicity performed by BAGG Engineers shows that the

site is underlain by Pleistocene age Marine-Terrace deposits, which are sand and gravel deposited on

uplifted marine-abrasion platforms along the coast. No earthquake faults cross the PFM alignment. The

probability of a major earthquake (Mw>6.7) with respect to the distance of active faults from the site are

shown in Table 1.

Field Assessment Results

Test Pit 1 The results from soil and groundwater sampling showed that the subsurface materials have a good

consistency. Five of the seven samples taken showed moderate corrosivity, and the other two samples

can be classified as mildly corrosive. The groundwater samples show negligible amount of chloride and

sulfate, and they all have pH close to 7. The resistivity of groundwater is classified as mildly to moderately

corrosive. The pipe wall loss detected using bracelet probe and UT gauge ranges from 15% to 49%.

Test Pit 1 Test pit 1 is located on Stanford Avenue near West Point Avenue, approximately 220 feet from the

Princeton Pump Station. The subsurface consists of an approximately 2-foot thick dark brown sandy clay

on top and an approximately 5-foot thick yellowish brown sandy lean clay and/or clayey sand. The force

main was uncovered at approximately 5 feet deep. Table 2 shows the results of soil sampling.

Soil sample TP-1-4 was obtained close to the force main. This sample was taken because signs of soil

oxidation were observed during excavation (Figure 4), and it was reported to have a pH value of 5.4.

AWWA C-105 assigns a point of 0 for pH values from 4 to 6.5, which suggests that although the soil

surrounding the pipe at this location is acidic, its corrosion effect on ductile iron pipe is limited. The

amount of chloride and sulfate detected in the soil is negligible, and no sulfide was detected. The

resistivity of soil at test pit 1 indicates that it is mildly to moderately corrosive.

Figure 4. Subsurface Soil Oxidation at Test Pit 1

Groundwater was encountered at approximately 5 feet deep in Test Pit 1. The results of groundwater

sampling (shown in Table 3) indicate that the groundwater is mildly corrosive.

The existing force main is assumed to be Class 52 based on advice from DIPRA. This means that it has a

pipe wall thickness of 0.33 inches. Approximate 3.8 feet of force main was scanned at test pit 1. The

bracelet probe initially detected outside diameter (OD) pitting at 4 locations. Some sections of the pipe

wall is generally thinner than the nominal thickness due to casting tolerance2. Carbonization3 was also

observed on the pipe exterior wall in Test Pit 1. After the surface carbon layer was carefully removed,

pitting on the exterior wall (Figure 5) was revealed at the locations pin-pointed by the bracelet probe,

which proved its accuracy. Note, the contractor applied bituminous coating on all the pitting areas after

bracelet probe scan was completed to protect the pipe from corrosion.

2 Casting tolerance is included in the nominal pipe wall thickness, and is typically 0.05 inches. Therefore the measured pipe wall thickness is expected to be between 0.28 and 0.33 inches Pressure Class 52 pipes. 3 When the ferrous material leached out of ductile iron, only a thin shell made of carbon deposit is left behind on the exterior pipe wall.

UT gauge readings were taken by PICA and BAGG to verify the bracelet probe readings on the pipe wall

thickness. The pipe wall thickness at each pitting location are shown in Table 4.

UT readings from PICA and BAGG are relatively close to each other, which confirmed that the bracelet

probe was able to read the pipe wall thickness fairly accurately. The pipe wall loss ranged from 12% to

33%. Considering that the PFM is a 40-year old pipeline, the wall loss percentage is considered acceptable.

Test Pit 2 Test pit 2 is located on California Avenue near the corner of Yale Avenue at approximately Station 25+50

on the PFM alignment. The subsurface at test pit 2 is similar to that at test pit 1 (see Figure 6). The force

main at this location is at a depth of approximate 4 feet.

Figure 6. Princeton Force Main at Test Pit 2

Two soil samples were taken at test pit 2 at depth of 2.25 ft and 4.75 ft. Table 5 shows the results of soil

sampling at this location.

The resistivity in the soil sample at depth of 2.25 feet is relatively low. However, this soil does not come

in direct contact with the force main pipe and therefore would not be a cause of pipe corrosion. The soil

that is in direct contact with the force main, at depth of 4.75 ft, shows only moderate corrosivity. The soil

pH at this location at both depths are close to neutral. Chloride and sulfate are negligible and no sulfide

was detected.

Groundwater sample was also taken at test pit 2, and the results are shown in Table 6.

Table 6. Groundwater Sampling Results at Test Pit 2

pH 7.2

Chloride (mg/Kg) 84

Sulfate (mg/Kg) 56

The resistivity in groundwater is relatively low, but pH is neutral and negligible amount of chloride and

sulfate were found in the groundwater sample. The overall corrosivity of groundwater at this location is

classified as mildly to moderately corrosive.

The force main in test pit 2 has a bell-spigot joint and bracelet probe could not perform scan over that

joint. Therefore, two groups of scans were conducted separately on either side of the pipe joint. The total

scanned length is approximately 2.1 feet. The bracelet probe detected three OD pitting locations on the

bell side and 2 OD pitting locations on the spigot side (Figure 7 and Figure 8).

The force main in test pit 2 shows similar wall loss ratio to test pit 1, with the exception of second OD

pitting. However, the area of actual pitting is fairly small and wall loss is not over 50%.

Test Pit 3

Test pit 3 is located near the discharge point of PFM on the south side of Highway 1. The force main is

located at approximately 4 feet deep. The subsurface condition at test pit 1 is similar to the other two test

42


pits. Two soil samples were taken at depth of 3 feet and 5 feet, and the sampling results are shown in

Table 8.

Resistivity at these soil samples indicates a moderate corrosivity. The pH is shown to be neutral. The

amount of chloride and sulfate is negligible, and sulfide was not detected.

Groundwater was sampled at test pit 3 and the results are summarized in Table 9.

The resistivity of groundwater sample also showed moderate corrosivity, close to neutral pH and

negligible amount of chloride and sulfate. A total of 2.4 feet of pipe segment was scanned at test pit 3.

The bracelet probe detected OD pitting at 3 different locations, and further UT readings were taken by

PICA and BAGG. The readings are summarized in Table 10.

3 (24.0, 10.0) 0.274 0.196 17% - 41% 0.220 – 0.248

The UT readings from PICA and BAGG don’t match very well at the 3rd pitting location, where a higher

percentage of wall loss ratio was reported by PICA. However, similar to the 2nd pitting location in test pit

2, this pitting has relatively small area.

43


The soil sampling results showed that the overall corrosivity can be considered as mild to moderate. The

groundwater sampling showed similar results. Among 12 OD pitting locations, the wall loss ratio ranges

between 15% and 49%. Only 2 of the 12 pitting locations showed a wall loss over 40%.

Conclusion The desktop and field condition assessment shows that the PFM is overall in good condition. Several

localized areas have higher wall loss ratio (41% and 49%), but given the age of this pipe, the amount of

wall loss is the industry acceptable range. A typical useful life of 100 years for ductile iron pipe could still

be expected of PFM. In addition, the surrounding soil and groundwater of PFM is only mildly to moderately

corrosive, and therefore is not a major cause for further exterior pipe wall corrosion.

It is recommended to monitor the pipeline and conduct another similar assessment in the next 10 years

to determine the rate of wall loss. During normal operation and maintenance, it is recommended to

maintain air release valve(s) on the force main regularly and replace them as necessary to assure optimal

performance.
