Summary
The purpose of this Audit is to document the identified areas of strength and deficiencies in the management, operation and maintenance of the sewer collection system for YYYY – YYYY.
This review is separated into two sections: Section 1 - Monitoring and Measurement, and Section 2 - SSMP Compliance and Effectiveness. This review is completed as part of the monitoring measurement, program modifications and audit process as described in SSMP Sections 9 and 10, respectively.
Section 1 – Monitoring and Measurement
This section includes collecting and summarizing the necessary data to evaluate the performance of the collection system based on the key performance indicators presented in Section 9 of the SSMP and listed below:
Number of SSOs
i. Per year
ii. Dry weather
iii. Per year by cause
Annual miles of sewer flushing/cleaning
Actual versus scheduled cleaning
Annual miles of CCTV inspection
System rehabilitation and repairs made
Annual record of pump station maintenance work orders
1.1 Number of SSOs
The City’s SSOs are summarized in Tables 1, 2, and 3 and Figures A1 and A2 for years YYYY to YYYY and are illustrated in the corresponding Figure 2-1 in Appendix D.

Provide narrative explanation with respect to sewer flushing and CCTV maintenance program, manhole and lift station inspections. Is the City maintenance goals; what were actual vs. scheduled? Is the City seeing any correlation with reduction in SSOs? Provide explanation for trends (i.e. reduction in linear feet of CCTV due to reduction in staffing, equipment failure or out to maintenance, etc.).
1.3 Sewer System Repairs
Provide a description of additions and improvements made to the sanitary sewer collection system; also a narrative explanation as to how these were discovered (during preventative maintenance, SSO, complaint, etc.) or if they were planned CIP projects. This will be beneficial for SSMP effectiveness evaluation.

APPENDIX F
GLOSSARY OF TERMS
Category 1 – Discharges of untreated or partially treated wastewater of any volume resulting from an enrollee’s sanitary sewer system failure or flow condition that:
Reach surface water and/or reach a drainage channel tributary to a surface water; or Reach a Municipal Separate Storm Sewer System (MS4) and are not fully captured and returned to the sanitary sewer system or not otherwise captured and disposed of properly. Any volume of wastewater not recovered from the MS4 is considered to have reached surface water unless the storm drain system discharges to a dedicated storm water or groundwater infiltration basin (e.g., infiltration pit, percolation pond).
Category 2 – Discharges of untreated or partially treated wastewater of 1,000 gallons or greater resulting from an enrollee’s sanitary sewer system failure or flow condition that do not reach surface water, a drainage channel, or a MS4 unless the entire SSO discharged to the storm drain system is fully recovered and disposed of properly.
Category 3 – All other discharges of untreated or partially treated wastewater resulting from an enrollee’s sanitary sewer system failure or flow condition.
CIWQS – The California Integrated Water Quality System (CIWQS) is a computer system used by the State and Regional Water Quality Control Boards to track information about places of environmental interest, manage permits and other orders, track inspections, and manage violations and enforcement activities. CIWQS also allows online submittal of information by Permittees within certain programs and makes data available to the public through reports.
Enrollee – A public entity that owns or operates a sanitary sewer system and has submitted a complete and approved application for coverage under Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (WQO No. 2006-0003-DWQ) Event ID – A unique identifier assigned by the CIWQS SSO Database to each reported SSO or private lateral sewage discharge.
Lateral (Service Lateral) – The segment of pipe which connects a private home, building, or development to the publicly owned sewer main. The responsibility for maintaining a lateral can be solely that of the sewerage agency or private property owner; or it can be shared between the two parties. Local communities and land ownership dictate lateral responsibility and the basis for a shared arrangement, if it applies. See Lower Lateral and Upper Lateral for more detailed definitions.
Lower Lateral – That portion of a lateral usually from the property line or easement line to the sewer main. Sewer agencies are typically not be responsible for maintenance of this portion of the lateral. The lower lateral is typically owned and maintained by the property owner of the property it serves.

Terms and Definitions
Term Definition
Average dry
weather flow
(ADWF)
The average flow rate or pattern from days without noticeable inflow or infiltration response. ADWF usage patterns for weekdays and weekends differ and must be computed separately. ADWF is expressed as a numeric average and may include the influence of normal groundwater infiltration (not related to a rain event).
Basin Sanitary sewer collection system upstream of a given location (often a flow meter), including all pipelines, inlets, and appurtenances. Also refers to the ground surface area near and enclosed by pipelines. A basin may refer to the entire collection system upstream from a flow meter or exclude separately monitored basins upstream.
Depth/diameter
(d/D) ratio
Depth of water in a pipe as a fraction of the pipe’s diameter. A measure of the fullness of the pipe used in the capacity analysis.
Design storm A theoretical storm event of a given duration and intensity that aligns with historical frequency records of rainfall events. For example, a 10-year, 24-hour design storm is a storm event wherein the volume of rain that falls in a 24-hour period would historically occur once every 10 years. Design storm events are used to predict I/I response and are useful for modeling how a collection system will react to a given set of storm event scenarios.
Infiltration and
inflow
Infiltration and inflow (I/I) rates are calculated by subtracting the ADWF flow curve from the instantaneous flow measurements taken during and after a storm event. Flow in excess of the baseline consists of inflow, rainfall-responsive infiltration, and rainfalldependent infiltration. Combined I/I is the total sum in gallons of additional flow attributable to a storm event.
Infiltration,
groundwater
Groundwater infiltration (GWI) is groundwater that enters the collection system through pipe defects. GWI depends on the depth of the groundwater table above the pipelines as well as the percentage of the system that is submerged. The variation of groundwater levels and subsequent groundwater infiltration rates are seasonal by nature. On a day-today basis, groundwater infiltration rates are relatively steady and will not fluctuate greatly.
Infiltration,
rainfalldependent
Rainfall-dependent infiltration (RDI) is similar to groundwater infiltration but occurs as a result of storm water. The storm water percolates into the soil, submerges more of the pipe system, and enters through pipe defects. RDI is the slowest component of stormrelated infiltration and inflow, beginning gradually and often lasting 24 hours or longer.
The response time depends on the soil permeability and saturation levels.
Inflow Inflow is defined as water discharged into the sewer system, including private sewer laterals, from direct connections such as downspouts, yard, and area drains, holes in manhole covers, cross-connections from storm drains, or catch basins. Inflow creates a peak flow problem in the sewer system and often dictates the required capacity of downstream pipes and transport facilities to carry these peak instantaneous flows.
Overflows are often attributable to high inflow rates.

V&A Project No. 21-0295 vi
Peak Wet
Weather Flow
The highest daily flow during and immediately after a significant storm event. Includes sanitary flow, infiltration, and inflow.
Peaking factor
(PF)
PF is the ratio of peak measured flow to average dry weather flow. This ratio expresses the degree of fluctuation in flow rate over the monitoring period and is used in the capacity analysis.
Surcharge When the flow level is higher than the crown of the pipe, then the pipeline is said to be in a surcharged condition. The pipeline is surcharged when the d/D ratio is greater than 1.0.
Synthetic
hydrograph
A set of algorithms has been developed to approximate the actual I/I hydrograph. The synthetic hydrograph is developed strictly using rainfall data and response parameters representing response time, recession coefficient and soil saturation.

Executive Summary
Scope and Purpose
V&A Consulting Engineers (V&A) has completed sanitary sewer flow monitoring and rainfall monitoring with inflow and infiltration (I/I) analysis within the City of Manteca (City) collection system. Flow and rainfall monitoring was performed for over two (2) months, from March 18, 2022, to May 19, 2022.
Open-channel flow monitoring was performed at 18 sites. There were three general purposes of this study.
1. Establish the baseline sanitary sewer flows at the flow monitoring sites
2. Establish the peak flow condition during the rainfall events and estimate available sewer capacity.
3. Quantify inflow/ infiltration (I/I) at the applicable flow monitoring sites.
Monitoring Sites
The flow monitoring site locations were selected and approved by Stantec and the City of Manteca and are listed in Table ES-1 and shown in Figure ES-1.

Rainfall Monitoring
The cumulative precipitation over the flow monitoring period was 40% of the historical average. One rainfall event was defined as shown in Figure ES-2, noting the following items:
▪ Event 1 from March 27 – 28, 2022 contained the bulk of the rainfall during the monitoring period.
On average, approximately 0.72 inch of rain fell.
▪ Despite the relatively small rainfall amount, numerous sites showed inflow responses. Please see Section 3.3.2 for the Inflow results.
Figure ES-2. Rainfall Over Monitoring Period – Triangulated to City Centroid Site Flow Monitoring and Capacity Results
Peak measured flows, and the hydraulic grade line data (flow depths) are essential to understanding the capacity limitations of a collection system. The following capacity analyses terms are defined as follows:
▪ Peaking Factor: Peaking factor is defined as the peak measured flow divided by the average dry weather flow (ADWF). Peaking factors are influenced by many factors, including size and topography of the tributary area, flow attenuation, flow restrictions, characteristics of I/I entering the collection system, and hydraulic features such as pump stations.
▪ For this report, peaking factors are reported, and PF >5 are highlighted in RED1; however, the City should refer to City standards when evaluating peaking factors. Peaking factor data should be used at the discretion of the City Engineer.
▪ d/D Ratio: The d/D ratio is the peak measured depth of flow (d) divided by the pipe diameter (D).
The d/D ratio for each site was computed based on the maximum depth of flow for the study.
Standards for d/D ratio vary from agency to agency, but typically range between d/D ≤ 0.5 and d/D ≤ 0.75
1 WEF Manual of Practice FD-6 and ASCE Manual No. 62 suggests typical peaking factor ratios range between 3 and 4, with higher values possibly indicative of pronounced I/I flows.

Infiltration and Inflow Analysis
Flow monitoring basins are localized areas of a sanitary sewer collection system upstream of a given location (often a flow meter), including all pipelines, inlets, and appurtenances. The basin refers to the ground surface area near and enclosed by the pipelines. A basin may refer to the entire collection system upstream from a flow meter or may exclude separately monitored basins upstream. I/I analysis in this report will be conducted on a basin-by-basin basis. For this study, subtraction of flows was required to isolate the drainage areas of some flow monitoring basins. The flow monitoring basins and basin isolation equations used to define the limits of the basin boundaries are listed in Table ES-3.

The following inflow/infiltration analysis results are noted:
▪ Basins 4, 5, 13, and 14 were excluded from the I/I analysis because they are either 1) they are under the influence of a pump station or 2) they showed little I/I response. Basin 15 was also excluded because most of the peak I/I response were from upstream basins. ▪ Basins 1, 2, 8, 12, 16, and 17 showed a negligible amount of combined I/I, thus were ranked lowest for combined I/I.
▪ Inflow: Respectively, Basins 7, 6, and 18 had the highest weighted, normalized peak I/I rates, an indicator of high inflow upstream from the flow monitoring basin. Basin 7’s peak I/I was higher than the other basins, making it a priority if peak I/I is important for the City. ▪ Combined I/I: Respectively, Basins 7, 10, and 9 had the highest weighted, normalized combined rates, an indicator of high combined I/I upstream from the flow monitoring basin. ▪ Groundwater Infiltration: No evidence of GWI was found in any basin

Recommendations
V&A advises that future I/I reduction plans consider the following recommendations:
1. Master Plan and Model Implementation: This study focuses on inflow and infiltration generation; the study results can be used to update the master plan and compare it with previous model assumptions and flow monitoring results.
a. Verify Interconnections and Overflows: understanding the interconnections and overflows can help with the master plan, basin isolation, and I/I analysis.
2. Capacity Analysis: Five sites surcharged during the monitoring period, and four sites (sites 1,4,10, and 11) exceeded more than 0.5 feet about the pipe crown. Global capacity constraints will be addressed in the updated master plan. The following possible capacity concerns are noted:
a. no site exceeded 0.5 d/D average dry weather level.
b. 0.5 inch of sediment was found in site 9, and five (5) inches was found in site 11. c. Sites 1, 2, 4, 10, and 11 surcharged during this study. Among them, Site 11 had a high surcharge of 4.17 feet above the pipe crown. This is partially due to the high amount of sedimentation discovered inside the pipe. The surcharges did not always occur during wet weather.
d. Site 4 was a smaller diameter (18-inches) compared to upstream Site 9 (27-inches) and acted as a bottleneck.
3. Determine I/I Reduction Program: The City should examine its I/I reduction needs to determine its needs and goals for a future I/I reduction program.
a. if peak flows, sanitary sewer overflows, and pipeline capacity issues are of greater concern, then priority can be given to investigating and reducing sources of inflow within the basins with the greatest inflow problems. The highest inflow occurred within Basins 7, 6, and 18, where Basin 7’s peak I/I was higher than the other basins, making it a priority if peak I/I is important for the City.
b. if total infiltration and general pipeline deterioration are of greater concern, then the program can be weighted to investigate and reduce sources of infiltration within the basins with the greatest infiltration problems. The highest combined I/I occurred in Basins 7, 10, and 9.
Additionally, no basin showed evidence of excessive GWI.
4. I/I Investigation Methods: Potential I/I investigation methods include the following:
a. smoke testing.
b. mini-basin flow monitoring.
c. night-time reconnaissance work to (1) investigate and determine direct point sources of inflow, and (2) determine the areas and/or pipe reaches responsible for high levels of infiltration contribution.
d. CCTV inspection.
5. I/I Reduction Cost Effective Analysis: The City should conduct a study to determine which is more cost-effective: (1) locating the sources of inflow/infiltration and systematically rehabilitating or replacing the faulty pipelines; or (2) continued treatment of the additional rainfall dependent I/I flow.

1 Introduction
1.1 Scope and Purpose
V&A Consulting Engineers (V&A) was retained by Stantec and has completed sanitary sewer flow monitoring and rainfall monitoring with inflow and infiltration (I/I) analysis within the City of Manteca (City) collection system. Flow and rainfall monitoring was performed for over two (2) months, from March 18, 2022, to May 19, 2022. Open-channel flow monitoring was performed at 18 sites. There were three general purposes of this study.
1. Establish the baseline sanitary sewer flows at the flow monitoring sites
2. Establish the peak flow condition during the rainfall events and estimate available sewer capacity.
3. Quantify inflow/ infiltration (I/I) at the applicable flow monitoring sites .
1.2 Flow Monitoring Sites
Flow monitoring sites are defined as the manholes where flow monitors are secured and the pipelines in which flow sensors are placed. Capacity analysis and flow rate information are presented on a siteby-site basis.
The flow monitoring sites were selected and approved by Stantec and the City of Manteca. Information regarding the flow monitoring locations is listed in Table 1-1 and illustrated in Figure-1-1. Detailed descriptions of the individual flow monitoring sites, including photographs, are included in Appendix A.

1.3 Flow Monitoring Basins
Flow monitoring site data may include the flows of one or many drainage basins. Flow monitoring basins are localized areas of a sanitary sewer collection system upstream of a given location (often a flow meter), including all pipelines, inlets, and appurtenances. The basin refers to the ground surface area near and enclosed by the pipelines. A basin may refer to the entire collection system upstream from a flow meter or may exclude separately monitored basins upstream, requiring basin isolation (subtraction of upstream flows). The I/I analysis results will be presented on an isolated basin basis. The basins, basin attributes, and basin isolation equations are listed in Table 1-2. Flow site locations in relation to the drainage basins are also shown in Figure-1-1.

2 Methods and Procedures
2.1 Confined Space Entry
A confined space (Photo 2-1) is defined as any space that is large enough and so configured that a person can bodily enter and perform assigned work, has limited or restricted means for entry or exit , and is not designed for continuous employee occupancy. In general, the atmosphere must be constantly monitored for sufficient levels of oxygen (19.5% to 23.5%) and the presence of hydrogen sulfide (H2S) gas, carbon monoxide (CO) gas, and lower explosive limit (LEL) levels. A typical confined space entry crew has members with OSHA-defined responsibilities of Entrant, Attendant, and Supervisor. The Entrant is the individual performing the work. He or she is equipped with the necessary personal protective equipment needed to perform the job safely, including a personal four-gas monitor (Photo 2-2). If it is not possible to maintain line-of-sight with the Entrant, then more Entrants are required until line-of-sight can be maintained. The Attendant is responsible for maintaining contact with the Entrants to monitor the atmosphere using another four-gas monitor and maintaining records of all Entrants if there is more than one. The Supervisor is responsible for developing a safe work plan for the job at hand before entering.
2.2 Flow Meter Installation
V&A installed ISCO 2150 area-velocity flow meters for temporary monitoring within the collection system. ISCO 2150 meters use submerged sensors with a pressure transducer to collect depth readings and an ultrasonic Doppler sensor to determine the average fluid velocity. The ultra sonic sensor emits high-frequency sound waves, which are reflected by air bubbles and suspended particles in the flow.
The sensor receives the reflected signal and determines the Doppler frequency shift, which indicates the estimated average flow velocity. The sensor is typically mounted at a manhole inlet to take Photo 2-1. Confined Space Entry Photo 2-2. Typical Personal Four-Gas Monitor ATTACHMENT 2

advantage of smoother upstream flow conditions. The sensor may be offset to one side of the pipe to lessen the chances of fouling and sedimentation where these problems are expected to occur. Manu al level and velocity measurements were taken during the installation of the flow meters, and again when they were removed, and compared to simultaneous level and velocity readings from the flow meters to ensure proper calibration and accuracy. Figure 2-1 shows a typical installation for a flow meter with a submerged sensor.
Figure 2-1. Typical Installation for ISCO 2150 Flow Meter with Submerged Sensor
2.3 Flow Calculation
Data retrieved from the flow meters is placed into a spreadsheet program for analysis. Data analysis includes comparison to field calibration measurements as well as necessary geometric adjustments as required for sediment (sediment reduces the pipe’s wetted cross-sectional area available to carry flow).
Area-velocity flow metering uses the continuity equation:
𝑄 = 𝑣 ⋅ 𝐴 = 𝑣 ⋅ (𝐴𝑇 − 𝐴𝑆)
where Q: volume flow rate
v: average velocity as determined by the ultrasonic sensor A: cross-sectional area available to carry the flow
AT: total cross-sectional area with both wastewater and sediment AS: cross-sectional area of sediment

2.4 Measurement Error and Uncertainty
For traditional engineering applications, measurement “error” is explained as a difference between a computed, estimated, or measured value and the generally accepted true or theoretically correct value.
It can also be thought of as a difference between the desired and the actual performance of equipment.
For equipment, an error is usually expressed as a percentage relative to accuracy (i.e., “…the velocity sensor has an accuracy of ±2% of the reading…”).
However, for this study and flow monitoring applications, the cause of the measurement difference is important, and a distinction will be made between the equipment not performing to industry standards (“error”) and expected inaccuracies (“uncertainty”) associated with monitoring technology limitations.
Gauging “error” occurs when the equipment is not performing to industry standards. This can occur as a result of the following common categories of conditions that can be encountered at a wastewater monitoring site.
▪ Malfunctioning equipment (i.e., a sensor is damaged, battery life ends, or a desiccant canister becomes saturated)
▪ Improper equipment choice or maintenance (i.e., the selected gauging equipment technologies are incompatible with hydraulic conditions within the sewer, or excessive gravel deposits are allowed to accumulate around the sensors without being removed)
▪ Improper equipment calibration (i.e., depth and/or velocity measurements are incorrectly taken within the sewer, or equipment is allowed to drift out of calibration) ▪ Field conditions within the sewer (i.e., foaming at the water surface that “blinds” an ultrasonic depth sensor, or toilet paper catching and accumulating on a combination sensor, blinding the acoustic Doppler velocity meter)
For flow monitoring applications, gauging “uncertainty” is used to describe and quantify the expected inaccuracies that result from the limitations of the technologies that utilize indirect measurements to quantify wastewater flow.
It is important to try and install flow meters in “ideal” flow conditions. Ideal flow conditions are generally defined as laminar flow in a straight-through, constant-slope pipeline with no disturbances (elbows, tees, hydraulic shifts, etc.) 10 diameters upstream and five (5) diameters downstream from the flow monitoring location. If ideal flow conditions are met, then an expected uncertainty of final flow ATTACHMENT 2
Stantec City of Manteca Sanitary Sewer Flow Monitoring and Inflow/Infiltration Study 2022 Methods and Procedures V&A Project No. 21-0295 8
calculation from an open-channel flow meter may be approximately ±5%. In many situations, ideal flow conditions cannot be met, and uncertainties increase.
Flow Addition versus Flow Subtraction
Due to the uncertainties involved in subtracting flows of similar magnitudes, the addition of flows at multiple monitoring sites is usually preferred over subtraction of flows. Subtraction becomes an issue especially when the flow difference from the subtraction falls within the measurement uncertainty range of the two larger flow data sets (i.e., subtracting a large flow from another large flow to obtain a small difference).
This concept is best demonstrated by the following example:
Meter A measures 2.00 MGD of flow and has an expected uncertainty of ±5%, thus the uncertainty range of the flow measurement is ±0.10 MGD.
Meter B measures 2.50 MGD of flow and has an expected uncertainty of ±6%, thus the uncertainty range of the flow measurement is ±0.15 MGD.
Meter C measures 0.50 MGD of flow and has an expected uncertainty of ±8%, thus the uncertainty range of the flow measurement is ±0.04 MGD.
▪ Scenario 1 – Flow Addition
▪ Meter A + Meter B = 2.00 MGD (±0.10) + 2.50 MGD (±0.15) = 4.50 MGD (±0.25) ▪ Overall uncertainty = ±0.25 / 4.50 = ±5.6%
▪ For flow addition, the final uncertainty is essentially a weighted average of the component uncertainties.
▪ Scenario 2 – Flow Subtraction, Large Flow less Small Flow ▪ Meter B - Meter C = 2.50 MGD (±0.15) - 0.50 MGD (±0.04) = 2.00 MGD (±0.19) ▪ Overall uncertainty = ±0.19 / 2.00 = ±9.5%
▪ For flow subtraction, the final uncertainty will always be greater than the component uncertainties.
▪ When subtracting a small flow from a large flow, the resulting uncertainties can still be manageable.
▪ Scenario 3 – Flow Subtraction, Large Flow less a similarly Large Flow ▪ Meter B - Meter A = 2.50 MGD (±0.15) – 2.00 MGD (±0.10) = 0.50 MGD (±0.25) ▪ Overall uncertainty = ±0.25 / 0.50 = ±50%
▪ When subtracting similarly sized flow rates, the resulting uncertainties may not be manageable.
In this example, uncertainty of ±50% may be considered unacceptable for confident analyses.
Scenario 3 is a very “real-world” situation. The uncertainties for Meter A and Meter B are extremely reasonable (indeed, most flow monitoring service providers would be extremely pleased with true meter uncertainties of ±5% to ±6%). However, the reality of the math is clear, and the above example demonstrates the concept of flow subtraction and compounding or inflating uncertainty ranges.
ATTACHMENT 2

The following points are emphasized concerning the items of this section:
▪ For subtraction of flows, the overall uncertainty can be an inflated value that far exceeds the component uncertainties.
▪ The smaller the resultant flow from the subtraction equation, the larger the percentage uncertainty. ▪ Whenever possible, basins flows should be directly measured, rather than calculated as subtraction of two or more flow meters.
▪ If flow subtraction cannot be avoided, it is better to have the magnitudes of the component flows be as dissimilar as possible.
2.5 Average Dry Weather Flow Determination
For this study, four distinct average dry weather flow curves were established for each site location:
▪ Mondays – Thursdays
▪ Fridays
▪ Saturdays
▪ Sundays
Flows for many sites differ on Friday evenings compared to Mondays through Thursdays. Starting around seven (7) pm, the flows are often decreased (compared to Monday through Thursday). Similarly, flow patterns for Saturday and Sunday were also separated due to their unique evening flow pattern. This type of differentiation can be important when determining I/I response, especially if a rain event occurs on a Friday, Saturday, or Sunday evening.
Figure 2-2 illustrates varying flow patterns for Site 1 within a typical dry week.

2.6 Flow Attenuation
Flow attenuation in a sewer collection system is the natural process of the reduction of the peak flow rate through redistribution of the same volume of flow over a longer period of time. This occurs as a result of friction (resistance), internal storage, and diffusion along the sewer pipes. Fluids are constantly working towards equilibrium. For example, a volume of fluid poured into a static vessel with no outside turbulence will eventually stabilize to a static state, with a smooth fluid surface without peaks and valleys. Attenuation within a sanitary sewer collection system is based upon this concept. A flow profile with a strong peak will tend to stabilize towards equilibrium, as shown in Figure 2-3.
ATTACHMENT 2
Stantec City of Manteca Sanitary Sewer Flow Monitoring and Inflow/Infiltration Study 2022 Methods and Procedures V&A Project No. 21-0295 11
Figure 2-3. Attenuation Illustration
Within a sanitary sewer collection system, each individual basin will have a specific flow profile. As the flows from the basins combine within the trunk sewer lines, the peaks from each basin will not necessarily coincide at the same time, and peak flows may attenuate prior to reaching the treatment facility due to the length and time of travel through the trunk sewers. The sum of the peak flows of the individual basins within a collection system will usually be greater than the peak flows observed at the treatment facility.
2.7 Inflow / Infiltration Analysis: Definitions and
Identification
Inflow and infiltration (I/I) consist of stormwater and groundwater that enter s the sewer system through pipe defects and improper storm drainage connections and is defined as follows:
▪ Inflow: Stormwater inflow is defined as water discharged into the sewer system, including private sewer laterals, from direct connections such as downspouts, yard and area drains, holes in manhole covers, cross-connections from storm drains, or catch basins. ▪ Infiltration: Infiltration is defined as water entering the sanitary sewer system through defects in pipes, pipe joints, and manhole walls, which may include cracks, offset joints, root intrusion points, and broken pipes.
Figure 2-4 illustrates the possible sources and components of I/I.

Figure 2-4. Typical Sources of Infiltration and Inflow
Infiltration Components
Infiltration can be further subdivided into components as follows:
▪ Groundwater Infiltration: Groundwater infiltration depends on the depth of the groundwater table above the pipelines as well as the percentage of the system submerged. The variation of groundwater levels and subsequent groundwater infiltration rates are seasonal by nature. On a dayto-day basis, groundwater infiltration rates are relatively steady and will not fluctuate greatly. ▪ Rainfall-Dependent Infiltration: This component occurs as a result of stormwater and enters the sewer system through pipe defects, as with groundwater infiltration. The stormwater first percolates directly into the soil and then migrates to an infiltration point. Typically, the time of concentration for rainfall-related infiltration maybe 24 hours or longer, but this depends on the soil permeability and saturation levels.
▪ Rainfall-Responsive Infiltration is stormwater that enters the collection system indirectly through pipe defects, but normally in sewers constructed close to the ground surface such as private ATTACHMENT 2
Stantec City of Manteca Sanitary Sewer Flow Monitoring and Inflow/Infiltration Study 2022 Methods and Procedures V&A Project No. 21-0295 13
laterals. Rainfall-responsive infiltration is independent of the groundwater table and reaches defective sewers via the pipe trench in which the sewer is constructed, particularly if the pipe is placed in impermeable soil and is bedded and backfilled with granular material. In this case, the pipe trench serves as a conduit similar to a French drain, conveying storm drainage to defective joints and other openings in the system. This type of infiltration can have a quick response and graphically can look very similar to inflow.
Impact and Cost of Source Detection and Removal
▪ Inflow:
▪ Impact: Inflow creates a peak flow problem in the sewer system and often dictates the required capacity of downstream pipes and transport facilities to carry these peak instantaneous flows.
Because the response and magnitude of inflow are tied closely to the intensity of the storm event, the short-term peak instantaneous flows may result in surcharging and overflows within a collection system. Severe inflow may result in sewage dilution, resulting in upsetting the biological treatment (secondary treatment) at the treatment fac ility. ▪ Cost of Source Identification and Removal: Inflow locations are usually less difficult to find and less expensive to correct. These sources include direct and indirect cross -connections with storm drainage systems, roof downspouts, and various types of surface drains. Generally, the costs to identify and remove sources of inflow are low compared to potential benefits to public health and safety or the costs of building new facilities to convey and treat the resulting peak flows.
▪ Infiltration:
▪ Impact: Infiltration typically creates long-term annual volumetric problems. The major impact is the cost of pumping and treating the additional volume of water, and of paying for treatment (for municipalities that are billed strictly on flow volume). ▪ Cost of Source Detection and Removal: Infiltration sources are usually harder to find and more expensive to correct than inflow sources. Infiltration sources include defects in deteriorated sewer pipes or manholes that may be widespread throughout a sanitary sewer system.
Graphical Identification of I/I
Inflow is usually recognized graphically by large-magnitude, short-duration spikes immediately following a rain event. Infiltration is often recognized graphically by a gradual increase in flow after a wet-weather event. The increased flow typically sustains for a period after rainfall has stopped and then gradually drops off as soils become less saturated and as groundwater levels recede to normal levels. Real -time flows are plotted against ADWF to analyze the I/I response to rainfall events. Figure 2-5 illustrates a sample of how this analysis is conducted and some of the measurements that are used to distinguish infiltration and inflow. Similar graphs have been generated for the individual flow monitoring sites and can be found in Appendix A.

Figure 2-5. Sample Infiltration and Inflow Isolation Graph Analysis Metrics
After differentiating I/I flows from ADWF flows, various calculations can be made to determine which I/I component (inflow or infiltration) is more prevalent at a particular site and to compare the relative magnitudes of the I/I components between drainage basins and between storm events:
▪ Inflow – Peak I/I Flow Rate: Inflow is characterized by sharp, direct spikes occurring during a rainfall event. Peak I/I rates are used for inflow analysis. 2 ▪ Groundwater Infiltration (GWI): GWI analysis is conducted by looking at minimum dry weather flow to average dry weather flow ratios and comparing them to established standards to quantify the rate of excess groundwater infiltration.
▪ Rainfall-Dependent Infiltration (RDI): RDI Analysis is conducted by looking at the infiltration rates at set periods after the conclusion of a storm event. Depending on the particular collection system and the time required for flows to return to ADWF levels, different periods may be examined to determine the basins with the greatest or most sustained rainfall-dependent infiltration rates. ▪ Combined I/I: The combined inflow and infiltration are measured in gallons per site and storm event. Because it is based on combined I/I volume, it is used to identify the overall volumetric influence of I/I within the monitoring basin.
2 I/I flow rate is the real time flow less the estimated average dry weather flow rate. It is an estimate of flows attributable to rainfall. By using peak measured flow rates (inclusive of ADWF), the I/I flow rate would be skewed higher or lower depending on whether the storm event I/I response occurs during low-flow or high-flow hours.
ATTACHMENT 2

Normalization Methods
There are three ways to normalize the I/I analysis metrics for an “apples-to-apples” comparison among the different drainage basins:
▪ per-ADWF: The metric is divided by the established average dry weather flow rate and is typically expressed as a ratio. Peaking Factors are examples of using ADWF to normalize data from different sites.
▪ per-IDM: The metric is divided by the length of pipe (IDM [inch-diameter mile]) contained within the upstream basin. Final units typically are gallons per day (gpd) per IDM. ▪ per-ACRE: The metric is divided by the acreage of the upstream basin. Final units typically are gallons per day (gpd) per ACRE.
The infiltration and inflow indicators were normalized by the per-ADWF, and per-ACRE methods in this report, and these results will be shown in the following I/I analysis results sections. For basin rankings, the following weighting decisions are given:
▪ per-ADWF: It is noted that abnormal waste usage could result in low ADWF values, which could skew results and lead to possible misinterpretation of data. Per-ADWF values are known and valid and will be assigned 51% weighting towards final rankings.
▪ per-ACRE: Per-ACRE values are known and valid and will be assigned 49% weighting towards final rankings.

3 Results and Analysis
3.1 Rainfall Monitoring
Rain Gauge Locations
V&A analyzed rainfall data from a total of five publicly available private weather stations (PWS) on Weather Underground (WU)3, allowing for solid coverage over the collection system which has a diverse range of topographical features. Figure 3-1 illustrates the locations and labeling convention used for the five rain gauges and their relation to the flow sites and basins.
Figure 3-1. Location of Rain Gauges, Flow Sites and Basins 3 Weather Underground (wunderground.com) collects data from 180,000+ weather stations across the country, including Automated Surface Observation System (ASOS) at airports, personal weather stations (PWS), and Meteorological Assimilation Data Ingest System (MADIS) managed by the National Oceanic and Atmospheric Administration (NOAA). While V&A has no direct control over the rain gauges, V&A performs additional QA/QC on the data to ensure its suitab ility for use.

The one main rainfall event (3/27/22 – 3/28/22) that elicited a solid I/I response over the flow monitoring period is illustrated in Figure 3-2. It can be seen that the intensity of the identified rain event is much higher than other rain events during the study period.
Figure 3-2. Rainfall Monitoring – Triangulated to City Hall of Manteca Table 3-1 shows the precipitation of the identified rainfall event and whole monitoring period for each rain gauge. The data showed that intensity of rain event 1 is uniform across the region and its precipitation is about 60% of the total precipitation during the flow monitoring period.

Regional Rainfall Event Classification
It is important to classify the relative size of a major storm event that occurs throughout a flow monitoring period5. Rainfall events are classified by intensity and duration. Based on historical data, frequency contour maps for storm events of given intensity and duration have been developed by the NOAA for all areas within the continental United States (Figure 3-4).
Figure 3-4. NOAA Northern California Rainfall Frequency Map For example, the NOAA Rainfall Frequency Atlas 6 classifies a 10-year, 24-hour storm event at the rain gauge location NW as 2.19 inches. This means that in any given year, at this specific location, there is a 10% chance that 2.19 inches of rain will fall in any 24 hours.
From the NOAA frequency maps, for a specific latitude and longitude, the rainfall densities for peri od durations ranging from 1 hour to 20 days are known for rain events ranging from 1-year to 10-year intensities. These are plotted to develop a rain event frequency map specific to each rainfall monitoring site. Superimposing the peak measured densities for the rainfall events on the rain event frequency plot determines the classification of the rainfall event. Table 3-2 shows the peak classifications for each rain event at each rain gauge location. Figure 3-5 illustrates the rain event classification plot at gauge location Outer SSE as an example. The following items are noted:

The rainfall affecting the sanitary sewer collection system basins must be calculated based on the proximity to the rain gauge locations. The mean precipitation for each site’s upstream basin was calculated by taking data from the rain gauges and using the inverse distance weighting (IDW) method.
IDW is an interpolation method that assumes the influence of each rain gauge location diminishes with distance. The center of an upstream basin 7 is identified, and a weighted triangulated average is taken of the precipitation data from nearby rain gauge locations.
The IDW function is as follows:
7 Note that the full basin upstream of the site was used instead of the isolated basins as the rain data will be compared to t he flow at each site

3.2 Flow Monitoring
Regarding Pump Stations
In this study, four sites were found to be under the influence of pump stations, Site 4, Site 5, Site 13, and Site 14. Figure 3-7 and Figure 3-8 showcased the pump station’s influence and I/I during the rain event on Site 4 and Site 13 as an example. It can be observed that both sites exhibited significant flow spikes, however they are not related to the rain event. Given the purpose of this study, those two sites will be excluded from I/I analysis and ranking.

Average Flow Analysis
Average dry weather flow (ADWF) curves were established during dry days when I/I had the least impact on the baseline flow. Table 3-4 summarizes the dry weather flow data measured for this study. ADWF curves for each site can be found in Appendix A. In Table 3-4, the observed sedimentation during site visit are highlighted in RED. The table provides the collection system flow at the flow monitoring sites when there is no influence from the rain. Figure 3-9 shows a flow schematic of the average.

Peak Measured Flows and Pipeline Capacity Analysis
Peak measured flows and the hydraulic grade line data (flow depths) are important to understanding the capacity limitations of a collection system. The peak flows and flow levels are the peak measurements as taken across the entirety of the flow monitoring period. Peak flows and levels may not correspond to a rainfall event or occur at the same time.
The following capacity analysis definitions will be used:
▪ Peaking Factor (PF) is defined as the peak measured flow divided by the average dry weather flow (ADWF). Peaking factors are influenced by many factors, including size and topography of the tributary area, flow attenuation, flow restrictions, characteristics of I/I entering the collection system, and hydraulic features such as pump stations.
▪ For this report, peaking factors are reported, and PF > 5 are highlighted in RED8; however, the City should refer to City standards when evaluating peaking factors. Peaking factor data should be used at the discretion of the City Engineer
▪ d/D Ratio is the peak measured depth of flow (d) divided by the pipe diameter (D). The d/D ratio for each site is computed based on the maximum depth of flow for the study. Standards for d/D ratio vary from agency to agency but typically range between d/D ≤ 0.5 and d/D ≤ 0.75 ▪ For this report, d/D ratios > 0.75 are highlighted in RED; however, the City should refer to City standards when evaluating d/D ratios, to be used at the discretion of the City Engineer.
Table 3-5 summarizes the peak recorded flows, levels, d/D ratios, and peaking factors per site during the flow monitoring period. Results of note have been shaded in RED. Capacity analysis data are presented on a site-by-site basis and represents the hydraulic conditions only at the site locations ; hydraulic conditions in other areas of the collection system will differ.

The following capacity analysis results are noted:
▪ Peaking Factors:
▪ Sites 6 and 13 had peaking factors over 5.
▪ Site 6 peak level, velocity, and flow occurred during a dumping event prior to a rainfall event, perhaps due to an industrial sewer release (see Figure 3-10). It occurred only once during the flow monitoring period of over 2 months, and probably does not need further investigation. ▪ The peaking factor of Site 13 may be skewed high due to low ADWF numbers. ▪ d/D Ratio:
▪ Sites 1, 2, 4 10, and 11 surcharged during the study. ▪ Site 11 surcharged 4.17 feet above the pipe crown.
Figure 3-11 and Figure 3-12 show bar graph summaries of the peaking factors and d/D ratios, respectively. Figure 3-13 shows the schematic diagram of the peak measured flows in each section with peak flow levels.

3.3 Inflow and Infiltration
Preface
Items relevant to the analysis in this study are noted below and referenced in Figure 3-14:
I/I Isolation: The I/I flow rate is the real-time flow less the estimated average dry weather flow rate (shown below as the RED line).
Inflow: Inflow is usually recognized graphically by large-magnitude, short-duration spikes immediately following a rain event. The peak inflow rate is the highest spike in the isolated I/I hydrograph immediately following the evaluated rainfall event.
RDI: RDI is typically taken as the average I/I flow rate measured approximately 24 to 36 hours after the rainfall event has concluded. For this study, no significant RDI was detected. Taking Site 6, for example, the I/I dropped to zero immediately after the peak of the rain event (see Figure 3-14). This may be due to the low permeability of soil, which failed to hold water during the rain event. As a result, no RDI study was conducted for this report.
Combined I/I: the totalized volume (in gallons) of both inflow and RDI over the course of a rainfall event (shown below as the orange area).

Inflow Results Summary
Inflow is storm water discharged into the sewer system through direct connections such as downspouts, area drains, cross-connections to catch basins, etc. These sources transport rainwater directly into the sewer system, and the corresponding flow rates are tied closely to the intensity of the storm. This component of I/I often causes a peak flow problem in the sewer system and often dictates the required capacity of downstream pipes and transport facilities to carry these peak instantaneous flows.
Table 3-6 and Figure 3-15 summarizes the peak measured inflow and inflow analysis results for the relevant flow monitoring basins; the top 3 ranked basins have been shaded RED. Figure 3-16 shows a summary of the inflow analysis results per basin.
The following inflow results are noted:
▪ Basins 7, 6, and 18 had the highest weighted, normalized peak I/I rates, an indicator of high inflow upstream from the flow monitoring basin; where Basin 7’s peak I/I was clearly higher than the other basins, making it a priority if peak I/I is important for the City. ▪ Basin 15 was excluded from the I/I analysis as most of its peak I/I response was from its upstream basins instead of the isolated basin. Basins 4, 5, 13 and 14 were also excluded due to the pump station influence.

Combined I/I Results Summary
Combined I/I analysis considers the totalized volume (in gallons) of both inflow and rainfall -dependent infiltration throughout a storm event.
Table 3-7 and Figure 3-17 summarize the captured Total flow rates. The “Top 3” basins for each category have been shaded in RED. Figure 3-18 shows the results on a map.
The following combined I/I results are noted:
▪ Respectively in order, Basins 7, 10, and 9 had the highest weighted, normalized combined rates, an indicator of high combined I/I upstream from the flow monitoring basin . ▪ Respectively in order, Basin 15 was excluded from the I/I analysis as most of its I/I response was from its upstream basins instead of the isolated basin. Basins 4, 5, 13 and 14 were also excluded due to the pump station influence.
▪ Basins 1, 2, 8, 12, 16, and 17 showed a negligible amount of combined I/I. “Negligible” means not quantifiable compared to regular noise.

Groundwater Infiltration Results Summary
ADWF can be expected to have a predictable diurnal flow pattern. While each site is unique, experience has shown that, given a reasonable volume of flow and typical loading conditions, the daily flows fall into a predictable range when compared to the daily average flow. If a site has a large percentage of groundwater infiltration occurring during the periods of dry weather flow measurement, the amplitudes of the peak and low flows will be dampened 9.
It can be useful to compare the low-to-ADWF flow ratios for the flow monitoring sites. A site with abnormal ratios, and with no other reasons to suspect abnormal flow patterns (such as proximity to a pump station, treatment facilities, etc.), has a possibility of higher levels of groundwater infiltration in comparison to the rest of the collection system.
Figure 3-19 plots the low-to-ADWF flow ratios10 against the ADWF flows for the relevant flow monitoring sites. The brown dashed line shows “typical” low-to-ADWF ratios per the Water Environment Federation (WEF). For this study, no basin showed evidence of ground water infiltration.
Figure 3-19. Minimum Flow Ratios vs ADWF11
10 The Minimum to Average flow ratio is calculated by taking the minimum flow and dividing by the ADWF value (using the Mon-Thu ADWF curve).
11 Due to attenuation, it should be expected that sites with larger flow volumes should not have quite the peakto-average and low-to-average flow ratios as sites with lesser flow volumes. This is why the WEF typical trend line’s slope is closer to 1.0 as the ADWF increases, as shown in the figure. -

Stantec City of Manteca Sanitary Sewer Flow Monitoring and Inflow/Infiltration Study 2022 Recommendations
V&A Project No. 21-0295 39
4 Recommendations
V&A advises that future I/I reduction plans consider the following recommendations:
1. Master Plan and Model Implementation: This study focuses on inflow and infiltration generation; the study results can be used to update the master plan and compare it with previous model assumptions and flow monitoring results.
a. Verify Interconnections and Overflows: understanding the interconnections and overflows can help with the master plan, basin isolation, and I/I analysis.
2. Capacity Analysis: Five sites surcharged during the monitoring period, and four sites (sites 1,4,10, and 11) exceeded more than 0.5 feet about the pipe crown. Global capacity constraints will be addressed in the updated master plan. The following possible capacity concerns are noted:
a. no site exceeded 0.5 d/D average dry weather level.
b. 0.5 inch of sediment was found in site 9, and five (5) inches was found in site 11. c. Sites 1, 2, 4, 10, and 11 surcharged during this study. Among them, Site 11 had a high surcharge of 4.17 feet above the pipe crown. This is partially due to the high amount of sedimentation discovered inside the pipe. The surcharges did not always occur during wet weather.
d. Site 4 was a smaller diameter (18-inches) compared to upstream Site 9 (27-inches) and acted as a bottleneck.
3. Determine I/I Reduction Program: The City should examine its I/I reduction needs to determine its needs and goals for a future I/I reduction program.
a. If peak flows, sanitary sewer overflows, and pipeline capacity issues are of greater concern, then priority can be given to investigating and reducing sources of inflow within the basins with the greatest inflow problems. The highest inflow occurred within Basins 7, 6, and 18, where Basin 7’s peak I/I was higher than the other basins, making it a priority if peak I/I is important for the City.
b. If total infiltration and general pipeline deterioration are of greater concern, then t he program can be weighted to investigate and reduce sources of infiltration within the basins with the greatest infiltration problems. The highest combined I/I occurred in Basins 7, 10, and 9.
Additionally, no basin showed evidence of excessive GWI.
4. I/I Investigation Methods: Potential I/I investigation methods include the following:
a. smoke testing.
b. mini-basin flow monitoring.
c. night-time reconnaissance work to (1) investigate and determine direct point sources of inflow, and (2) determine the areas and/or pipe reaches responsible for high levels of infiltration contribution.
d. CCTV inspection.
5. I/I Reduction Cost Effective Analysis: The City should conduct a study to determine which is more cost-effective: (1) locating the sources of inflow/infiltration and systematically rehabilitating or replacing the faulty pipelines; or (2) continued treatment of the additional rainfall dependent I/I flow.

Technical Memorandum No. 1: Hydraulic Model Software Selection Manteca Wastewater Master Plan / 184031535 1
1 Introduction
The City of Manteca’s Wastewater Master Plan and Sewer Rate Study will focus on the sustainability of the City’s capability and capacity to convey and treat incoming wastewater flows.
In order to meet the goals of the Wastewater Master Plan, and in absence of an existing hydraulic model of the City’s existing collection system, one of the first steps of this plan is to select an analysis tool that best suits the objectives of this study and to support ongoing monitoring and assessment of the City wastewater infrastructure. The selection of hydraulic modeling software is an important long-term decision / investment to support these needs.
This memo summarizes a review of commercially available open-channel flow hydraulic models for the purposes of efficiently executing the Collection System components of the Wastewater Master Plan. This includes a high-level comparative review of the potential software candidate capabilities, licensing requirements, training needs, and costs, and to select the best fit for Manteca’s needs.
The potential software candidates that we have identified in this memo have varying strengths and limitations, and the selection of a particular software is often based on a combination of long-term modeling objectives, software capabilities and features, integration with other system software (CAD / GIS / Asset Management), end-user capabilities, software sustainability, and cost (to name a few). Note that the cost of most software packages is subscription-based and carry an annual fee, but in some cases can also vary in cost by model size (# of pipes) and software extension modules.
Manteca’s existing sewer collection system includes more than 5,000 GIS pipe links, with varying data completeness for physical attributes (invert elevations, etc). While it has not been decided if the model will be “full-pipe” or consolidated as a trunk model (i.e. 8” or 10” and larger sewers only), which will be further confirmed during the model development phase, the comparison of software costs will evaluate only software capable of modeling more than 5,000 pipes.
Stantec has a specialized, integrated team of hydraulic modelers with experience in developing, calibrating, testing, and analyzing computer models that simulate the hydraulics of wastewater collection systems. Our team has experience in the development, calibration and use of several different modeling platforms, including (but not limited to): DHI Mike+ (i.e., MikeUrban); Innovyze InfoSWMM & Infoworks ICM; CHI PCSWMM and other potential model platforms. Our team does not have commercial interests in any of the software candidates and have the capabilities to use any of the software reviewed.
There are several software developers for wastewater collection system models, including, but not limited to, Innovyze, Bentley, Danish Hydraulic Institute (DHI), Computational Hydraulics International (CHI), and the Environmental Protection Agency (EPA). Of this list, Innovyze, Bentley, and DHI offer multiple software platforms with varying capabilities, user interfaces, and computation engines. The following commentary provides a brief summary of each software - with the header providing a hyperlink to the developer website and developer sourced excerpts noted in “quoted italics”.
A detailed comparison matrix is included in Appendix A.

2 Software Candidates
2.1 EPA SWMM 5
EPA Stormwater Management Model (SWMM) 5
“EPA's Storm Water Management Model (SWMM) is used throughout the world for planning, analysis, and design related to stormwater runoff, combined and sanitary sewers, and other drainage systems. It can be used to evaluate gray infrastructure stormwater control strategies, such as pipes and storm drains, and is a useful tool for creating cost-effective green/gray hybrid stormwater control solutions. SWMM was developed to help support local, state, and national stormwater management objectives to reduce runoff through infiltration and retention, and help to reduce discharges that cause impairment of waterbodies.
SWMM is a Windows-based desktop program. It is open source public software and is free for use worldwide. SWMM contains a flexible set of hydraulic modeling capabilities used to route runoff and external inflows through the drainage system network of pipes, channels, storage/treatment units and diversion structures. These include the ability to do the following:
• Handle drainage networks of unlimited size.
• Use a wide variety of standard closed and open conduit shapes as well as natural channels. • Model special elements, such as storage/treatment units, flow dividers, pumps, weirs, and orifices.
• Apply external flows and water quality inputs from surface runoff, groundwater interflow, rainfalldependent infiltration/inflow, dry weather sanitary flow, and user-defined inflows. • Utilize either kinematic wave or full dynamic wave flow routing methods. • Model various flow regimes, such as backwater, surcharging, reverse flow, and surface ponding. apply user-defined dynamic control rules to simulate the operation of pumps, orifice openings, and weir crest levels.
• Percolation of infiltrated water into groundwater layers. • Interflow between groundwater and the drainage system. • Nonlinear reservoir routing of overland flow. Runoff reduction via LID controls.
SWMM accounts for various hydrologic processes that produce runoff from urban areas, which include the following:
• Runoff reduction via green infrastructure practices.
• Time-varying rainfall (precipitation) and evaporation of standing surface water. • Snow accumulation and melting.
• Rainfall interception from depression storage.
• Infiltration of rainfall into unsaturated soil layers. • Percolation of infiltrated water into groundwater layers Interflow between groundwater and the drainage system.
• Nonlinear reservoir routing of overland flow.”

The EPA SWMM5 software includes a very basic interface, without built-in GIS capabilities and does not have sophisticated model development and output tools. The EPA SWMM5 computational engine, however, as an open source code, is used by other software developers (xxxSWMM variants) that have developed integrated GIS-based interfaces with numerous capabilities and user tools to streamline model development, calibration, and output analysis of 1-D stormwater and wastewater collection system models.
The SWMM5 engine uses the RTK method to model rainfall dependent inflow and infiltration (RDII), by applying up to three (3) overlapping triangular unit-hydrographs against time that combine to simulate the short-term, medium-term, and long-term response of RDII entering the sewer system based on a rainfall timeseries. R represents a fraction of rainfall that enters the sewer system, T is the time from the onset of rain until the peak, and K is the ratio of the time to recession from the peak of the hydrograph to zero.
The RTK is a widely used method of simulating the RDII response in sewer collection systems and is used by all models evaluated in this memo, with the exception of Mike+ that when additional modules are purchased can also model physical hydrologic and subsurface parameters for the same purpose.
Hyperlink to more information on the RTK Method.
While the software is used extensively worldwide, and technical resources are available on-line, there is no developer support or training available for new users unfamiliar with the software.

2.2 Innovyze:
“Innovyze provides the industry's largest global offering of stormwater, sewer network, and flood modeling solutions – designed to meet the needs of your project and organization.” Our evaluation of potential candidates from Innovyze include only InfoSWMM and Infoworks ICM as they are the most prevalent options from this developer. Innovyze is also the vendor for the InfoSewer* and XPSWMM* software however were excluded as they may be phased out by Innovyze within the next 5 years or so.
2.2.1 INFOSWMM
InfoSWMM (Innovyze)
InfoSWMM is a “static 1D modeling within ArcGIS for capacity analysis and planning of gravity sewer systems” and largely an integrated front-end interface and GIS-based application with numerous capabilities and user tools to streamline model development, calibration, and output analysis for EPA’s SWMM5 computational engine (capabilities noted above under EPA SWMM5). The model can import and export to/from EPA SWMM 5, and does not limit model size to a fixed number of links (pipes). The developer interface and tools significantly improve efficiency and accuracy in model development, error checking, calibration, and output analysis.
The developer offers different “packages” (at varying price points) that “Tailor[s] InfoSWMM to your requirements with Modules, Suite Extensions, or the standalone version:
InfoSWMM Suite package:
• Calibrator: Automate model calibration
• DWF Allocator (Dry Weather Flow): Apportion dry weather flow from GIS elements • Designer: Optimize system design and costs
• Conduit Storage Synthesizer: Capture system storage for simpler forcemain models • Subcatchment Manager: Automate runoff models directly from terrain • Risk Assessment Manager: Compute flood risk and damage InfoSWMM Executive Suite package:
• Pond Design Manager: Extract and design storage systems • RDII Analyst (Rainfall-Derived Inflow and Infiltration): Decompose measure flow into model RTK inputs (R, T, K parameters for RDII prediction)
• NetVIEW (exporting to GIS / Google Earth)”
The InfoSWMM software is popular among other large municipal agencies throughout the US, and the developer offers extensive support and training opportunities. The pricing of this software is moving to an annual fee subscription service, and is anticipated to cost upwards of $10,000/year (awaiting developer quote, to be confirmed…).

Technical Memorandum No. 1: Hydraulic Model Software Selection Manteca Wastewater Master Plan / 184031535 5
2.2.2 INFOWORKS ICM
Infoworks ICM (Innovyze)
Infoworks ICM is Innovyze’s flagship hydraulic modeling platform, based on a proprietary computational engine, that integrates 1D collection system modeling with 2D surface modeling - typically found in a combined sewer system that is heavily impacted by direct surface inflows, ponding and CSOs. Infoworks offers a 1-D only Sewer Edition (SE), specifically for wastewater collection systems that do not require the integration and conveyance of surface flows.
This software includes very sophisticated GIS-based model development and analysis tools, including notable advanced hydrologic parameters and response models for rainfall dependent inflow and infiltration (RDII) simulation, real-time control, calibration and visualization and output capabilities. It is used by many large municipal agencies throughout the US, but due to its advanced capabilities is also one of the most complicated commercial models and most expensive on the market. The pricing of this software is moving to an annual fee subscription service, and is anticipated to cost upwards of $15,000/year (awaiting developer quote, to be confirmed…).
2.3 Bentley: SewerGEMS
SewerGEMS (Bentley)
SewerGEMS is a versatile software from Bentley that uses a proprietary computational engine that has the ability to use kinematic wave (steady state and extended period simulations with no surcharging or backflow), gradually varied flow solver, or the dynamic wave 1-D St. Venant equations using either an implicit dynamic solution or an explicit dynamic solution (SWMM5 engine). The model interface can be used in several ways, either as a stand-alone interface, or integrated within ArcGIS, AutoCAD, MicroStation, or OpenRoads Designer (Civil license). It includes many useful model development tools including a sewage (load) allocation module, calibration modules, and offers one of the most robust scenario management capabilities of any commercially available software. The output result visualization capabilities of SewerGEMS are not as sophisticated when compared to other software (InfoWorks, InfoSWMM, PCSWMM), and the model cannot be exported to a SWMM5 file for use in other platforms, requiring model users to have a subscription to the software.
Pricing for Bentley’s OpenFlows SewerGEMS software is based on an annual subscription, with a starting fee for a 5,000 pipe model is $7,638/year increasing to over $10,000/year for a 10,000 pipe limit.

2.4 DHI: Mike+
Mike+ (DHI)
Mike+ is a very sophisticated hydraulic modeling software that has the ability to integrate both water distribution system modeling and open-channel flow modeling (sanitary and storm) within the same platform. This software is the successor to MikeUrban, its predecessor, used by many large municipal agencies throughout the world. It is a GIS-based program that activates various software modules that hosts and pulls physical model attributes and input parameters from a detailed structure of related geodatabases and solution engines. The software has ability to model complex systems using dynamic wave computations with real-time control (RTC) capabilities and using either the RTK RDII models or a more complex simulation that models physical hydrologic and subsurface parameters to derive RDII responses. Mike+ is meant for use by expert-level users and extensive software documentation and developer support is available.
The cost of the Mike+ base license that includes only the SWMM module for open channel flow is approximately $3,000/year (the base license does not integrate with ArcGIS), and approximately $10,400/year if the Collection System Modules (includes ArcGIS, SWMM+Mike1D Pipeflow, and Rainfall Runoff, Control and Transport extensions).
2.5 CHI: PCSWMM
PCWMM (CHI)
PCSWMM is a complete interface and suite of analysis tools for the SWMM5 engine. It is a stand-alone GIS interface that offers support for over 50 GIS/Shapefile formats, importing / exporting functions for excel, topological tools for model development, digital elevation models, automatic watershed delineation, and access to map services from Microsoft and other web map services. PCSWMM offers unlimited model size and complexity, and can use distributed computing systems to solve large model computations if necessary. It includes very sophisticated model development and error checking routines, time series management and output visualization tools and other analysis tools that streamline the analysis of collection system performance. It is also one of the most user-friendly software available, offers extensive training and support, as well as access to widely used open-source codes, peer-reviewed journals and OpenSWMM community posts.
PCSWMM also has 1D and 2D modeling capabilities (to model surface flows in either combined sanitary or stormwater networks), and also can be used as an interface for water distribution modeling using the EPANET hydraulic model engine. PCSWMM’s scenario management tools are extensive and useful in managing multiple scenarios, but considered rudimentary and not as transparent when compared to SewerGEMS.
The PCSWMM is priced at approximately $1,200/year for the Professional 1D version and approximately $1,800/year for the Professional 2D version.

4 Comparison and Ranking Matrix
A simple comparison matrix was developed to rank each of the software against each other using a relative weighting system that attempts to consider our knowledge of Manteca’s needs for this project and for the sustainability of managing the ongoing and future performance of the collection system. Many criteria were evaluated, including several criteria under 5 main performance areas including:
• GIS interaction Criteria
• Modeling Capabilities
• Engineering Criteria
• User Interfacing Criteria
• Commercial Criteria
The weighting value (importance to Manteca) of each Technical Criteria was based on the following:

5 Conclusion
Based on this analysis, the highest rank (yet lowest cost at $1,200/year) software is PCSWMM.
The 2nd highest ranked software is InfoWorks ICM, however the costs are significantly higher for this and the remaining candidates.
Based on our previous experience in completing similar projects in central California (Concord, Merced, Grass Valley, Lincoln, etc) and throughout North America, we can confidently recommend the use of PCSWMM to the City of Manteca as a cost-effective, user friendly, yet very powerful modeling software that uses based on the EPA SWMM engine. We are very confident in the PCSWMM model software as it will save significant time and effort in the model development and future system analysis for this study.
We trust this memo provides the City with an objective review of available hydraulic models available for use on the Manteca Wastewater Master Plan, and if you have any questions or concerns, we are available at your convenience to discuss.
