3B. Domestic Water System
Description
The domestic water system will be
reviewed to accurately understand
and document all facilities, capacities,
and processes, as well as a developing
complete representation of the existing
domestic water distribution system.

The City’s domestic water system has
four sources entering the distribution
system: two MWD feeder services,
Santa Monica Well 1, and the Arcadia
Water Treatment Plant. Both MWD
connections are 24” diameter and can
maintain a hydraulic grade capable of
direct service to all three pressure zones
within the City’s service area. Typically,
the distribution system demand is
served between 30 - 40% through
these MWD connections, and the rest
is supplied from City owned ground
water wells. Multiple reservoirs are also
connected to the distribution system
including Riviera Reservoir, Mt Olivette
Reservoir, and San Vicente Reservoir. Figure 7. Potable Water System Map from 2020 Urban Water Management Plan 3C. Historical and Current Water Use
The City’s water consumption has dropped in recent
years due largely to conservation efforts by the City
across the customer base. Declines in consumption also
can result in additional water quality challenges due to localized areas of increased water age. Reviewing historical consumption data to identify trends in consumption based on location and customer class will be important for better understanding the future direction of water use. We will work with our partner Maddaus, who is currently looking at water use data as part of the conservation plan, to review finished water production for the entire system, pressure zone flows, and residential, commercial, and industrial customer metered usage. The difference between
production and billed usage will be used to determine
non-revenue water, which will also be broken out for each pressure zone. Minimal non-revenue water has historically been observed by the City (1.6% in 2016 and negative in more recent years – like due to metering inaccuracies), so calculated values will be corroborated with other reports and the City’s experiences to use the best estimate for modeling.

Once base demands are established, demand scaling
factors must be identified to extrapolate demands
allocated to each customer meter location to project
average, maximum daily, and peak hourly system flow
conditions unique to each pressure zone and customer
class. Our deep technical knowledge of modeling, demand forecasting and planning will ensure the results of this task provide realistic and practical factors throughout each hour of the day.

Seasonal, daily and hourly demands vary from
community to community based on variables, such as
climate, climate change, customer types, and areas of
irrigation based on economic factors. It is important that appropriate demand peaking factors be selected so that
water system improvements are not unduly oversized,
thus increasing costs and creating water quality concerns.

Our technical experts will work with the City to review the data to determine appropriate factors to use for each pressure zone while considering the impacts on systemwide peak demands.

Diurnal patterns reflect the varying usage of water
throughout a typical day and are important for
understanding not only the impact of peak demand
conditions on the performance of the distribution system, but also the impact of low demand periods on water
quality, which allows the City to better understand these and simulate improvements to address any challenges.

Representative demand patterns will be developed
for each pressure zone based on flow data and water
balances for each area.

In addition to average, max, and peak demand conditions, maximum day demand plus fire flow (MDD+FF) will
also be developed. One of the primary factors in sizing, operating and designing water distribution infrastructure is meeting specific capacity requirements to provide
adequate fire suppression. Various guidance manuals are relied on to support this, including AWWA M32, AWWA
M17, and NFPA 291, but many systems establish general
required fire flow guidelines depending on the customer type or land use type. Based on our team’s industry
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 29 E // 1.5 PROJECT WORK PLAN
expertise, and through coordination with the City, the correct MDD+FF demand will be identified for use during model development and system evaluations. This way the most appropriate fire suppression guidelines will be applied when sizing future capital improvements.
3D. Future Water Use
Modeling future demand projections is a critical component of recommending any improvements or changes to a water distribution system. This task will build off the Water Conservation Master Plan currently being developed by Maddaus.

Near term (2025) and far term (2040) planning horizons for future demands will be considered; demand projections under multiple future planning years will assist with prioritizing and sequencing recommended improvements projects for ECWA.

Based on the latest Urban Water Master Plan, demands may see an overall slight increase or relatively flat demand through 2040 due to balances of new developments and conservation efforts. Demand forecasts from this and other studies, along with information directly from the City, will be incorporated into final values by land use and pressure zone. This will also be combined with future development information like the recently adopted 6th Housing Elements.

Future demands will be allocated
in the model and maintained in
a logical scenario and alternative
hierarchy in the modeling
software. Future demands will
be differentiated from existing
demands using different demand
categories, different named
demand patterns (e.g., “20-year
Future Residential Demand
Pattern”), and appropriately
named scenarios, data sets,
and alternatives. The purpose
of careful naming conventions
for future demands is to assist
the various users of the model
in easily differentiating between
existing and future demands in
the model. Whereas existing
modeled demands are based on
detailed water billing information
and geospatial locating of water
customers, sets of assumptions,
estimations, and trend data are
incorporated into future demands.
3E - Current and Future Water Supply
Current and future water supply for the City will be analyzed such that they may be incorporated into the modeling and master planning effort. Based on the 2018 Sustainable Water Master Plan Update & 2020 Urban Water Management Plans, ground water makes up around 65% of the current potable water supply while the rest is imported from MWD connections.

Ground water currently comes from the Charnock, Olympic, Arcadia sub-basins through multiple ground water wells owned by the City. Arcadia Water Treatment Plant treats much of this ground water before discharging into the water distribution system. Limited recycled water is also utilized by the City through the Santa Monica Urban Runoff Recycling Facility; this flow currently makes up around 1% of the total water supply.

In the future, the City wants to increase groundwater utilization and reduce imported water. Groundwater increases are planned through a combination of Olympic well field restoration, groundwater recharging efforts, and Arcadia WTP expansion and enhancements. The City also anticipates an increase in non-potable recycled water use that may also help offset imported water usage. The City desires to have the first direct potable reuse (DPR) application in CA where water from the new AWTF would be distributed to customers, depending on future finalized DPR regulations. The City is also considering brand new water sources including new wells near the airport, and the option to consider desalination in the future; these may be considered and analyzed further in optional Task 7.1.

3F. Update Domestic Water System Hydraulic Model
Model updates consist of accurate representation
of system infrastructure, applying updated demand
allocation, factors and patterns, and matching model
reactions to changing conditions such as pump starts
and stops to recent SCADA system data. The purpose of
this task is to bring the model up-to-date with current conditions within the system and bring the model to a
level of detail aligned with current industry trends. This will be accomplished by the Arcadis team with a mindset for
future use of the model and allow for easy of long-term model maintenance by the City.

Following a review of the GIS database, any necessary
revisions to model pipes will be performed in collaboration with the City. The current industry trend is for modeled pipes to have a one-to-one relationship with the associated GIS database.

Arcadis has developed multiple tools to allow for a
seamless GIS-model interoperability, as well as ongoing improvements available in the existing built-in tools within InfoWater modeling software. We will develop a clear and concise process to maintain this GIS integration and make sure appropriate updates are passed to the respective
systems. Any tools necessary to do this will be provided to the City for long-term model maintenance.
3G. Domestic Water System Hydraulic Model Calibration and Analysis visualize the calibration results at multiple locations and for multiple scenarios.

2. Similarly, we have developed computer scripts which
directly read the InfoWater database of comparison of
multiple scenarios within the model. This visualization of comparison provides an efficient means to
understand the impact of any changes during
calibration from adjustment to adjustment.

3. We will work closely with City staff during the
calibration process to understand any anomalies and
develop solutions. In consultation with City staff, we
will use a macro and a micro calibration approach for
the model calibration. During workshops and progress
meetings, we will collaboratively develop a set of
criteria for macro and micro calibration. For example,
Figure 9. Examples of model connectivity challenges that need resolved during model updates Examples of quality assurance and adjustments of
horizontal piping assets that are common include:
• Topology, connectivity, disconnected pipes, parallel
pipes, and intersecting pipes
• Nodes in close proximity, disconnected nodes, pipesplit candidates • Hydrants and hydrant laterals (their inclusion,
representation, connectivity, and model attributes)
• Diameter discrepancies and model representation with
facility boundaries
Examples of model updates to vertical assets such as
pumps, tanks, and valves, include the following and any other updates deemed necessary through the model
calibration effort:
• Confirm pump simulations align with the recent pump
test data and perform any necessary updates
• Confirm valve position and settings align with available operational data
• Where possible, headloss curves may be added to
better represent remotely controlled positioning valves • All control valves (such as Pressure Reducing Valves) will be reviewed for correct sizes, configuration, and
settings.

Model calibration is believed by the water industry to be the most technically challenging aspect of modeling (per a survey by the AWWA Engineering Modeling Applications
Committee). We bring a proven approach and unique
tools that will accelerate the model calibration process.

Blending our depth of calibration experience with innovative approaches proposed specifically for this project, we feel our plan offers efficient and effective methods resulting in an exceptional model of the City water distribution system.

Our approach consists of the following calibration tools:

1. Our team has developed computer scripts to directly
read the InfoWater database and bring results into
Microsoft Excel and PowerBI for automated comparison
of calibration data. This, along with calibration SCADA templates developed by our team, will make it easy to
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 31 E // 1.5 PROJECT WORK PLAN
the criteria could be that pressure at a node is within 4 pounds per square-inch (psi) of the measured data. During macro calibration parameters like pressure zone diurnal curves and demand at a node can be adjusted to match model pressures to field observed data. Alternatively, during micro calibration parameters like pipe roughness factors will be adjusted to match model results to observed data. City staff will be updated and consulted with before and after any major updates.

Available SCADA and hydrant testing data from the City will be utilized for model calibration to represent conditions for at least a 24-hour time period. An option to extend the project to include field data collection (Task 7) is also included which would supplement the City’s available data with additional pressure and hydrant flow data; this would improve data available and thus may improve calibration results. The measure of model calibration is the primary tool to communicate the level of confidence and representativeness of the model computer simulations to the actual system. Common measures define a threshold allowable variation for each measurement or as percentage variance.

However, every system has facilities which are more critical for the model than others. Prior to model calibration, the Arcadis Team will conduct a workshop with City staff to define an innovative measurement of calibration, considering multiple factors such as shape of a curve, difference in actual values, and importance of facilities.

Figure 10. Hydraulic Model Calibration Process Schematic. Documenting the complete process is important to our team so that the City modelers and staff can reference this in the future, and for confidence and buy-in of model calibration and capabilities.

Once the model calibration is complete, we will create necessary scenarios and data sets within the model for existing system conditions, future system conditions/demands, and various system evaluations. Master plans require a number of model scenarios to be developed under a variety of demand conditions. The Arcadis team is highly experienced with creating organized hierarchical structures for dozens (and even hundreds) of model runs. We know and understand the importance of setting scenarios up correctly the first time and making sure that the structure is flexible to accommodate additional scenarios in a logical framework.

To support the City’s management of its water system, Arcadis will identify system performance level of service requirements. These level of service requirements typically consist of acceptable thresholds for pressure, velocity, headloss gradient, tank turnover, water age, and water quality concentrations. Any areas of low system performance as defined by the level of service criteria established for the system will be reviewed with the City to help collaborate on system improvements that will be included in the CIP.

Arcadis also places emphasis on providing an exceptional customer experience for our projects. For this project, in addition to paper maps for results presentation throughout the project, we propose to offer results presentation through interactive online map and Analytic and Collaboration Environment (ACE) dashboards hosted within ESRI’s ArcGIS Online . This will allow the City and Stakeholders the ability to see interactive model results outside of model software, customized to a specific login. While paper maps are a great tool to visualize systemwide model output, the use of these online dashboards with interactive maps allow the user to zoom, select a specific pipe or node and see detailed results.

This will be used by the project team throughout execution to collaborate and see specific model status and results; these will be available for one month following final project deliverables and can also be transferred to the City for continued use.

Figure 11. Arcadis’s Analytics & Collaboration Environment (ACE). In addition to paper maps, model results throughout the project will be communicated to the City through ACE which allows the City to understand model output through an interactive platform and to select and see model output for any individual asset. 3H. Water Quality Regulations Analysis
Water quality regulatory landscape continue to evolve at the national and state levels. Regulations affecting water systems continue to become more stringent. Arcadis’ water quality experts will assist the City to navigate and stay proactive. There are several key regulatory actions that could impact the City’s operations and maintenance through the planning horizon. Based on our understanding of the City’s system, the ones to focus on are 1,4-dioxane. The City currently treats for 1,4-dioxane and VOCs at Arcadia WTP. A progressive design build project to address 1,4-dioxane is also underway at Arcadia WTP.

Although unlikely to affect the drinking water system, per- and polyfluoroalkyl substances (PFAS) has been detected in the City stormwater and sewer flows feeding SMURRF so potential PFAS related regulations are another to keep track of. As an optional value-added service (see Task 7.4.4), Arcadis proposes to assess the potential for regulatory action under the Clean Water Act (CWA) and other regulations to affect discharges and examine potential alternatives for the management of RO concentrate and/or combined wastewater flows.

For this Task 3H, Arcadis will track the following regulations with the focus on 1,4-dioxane. • Third Six-Year Review
• Fourth Unregulated Contaminant Monitoring Rule (UCMR4) • Fifth Unregulated Contaminant Monitoring Rule (UCMR5) • Lead and Copper Rule Revisions
• Potential Per- and Polyfluoroalkyl Substances (PFAS) related regulations • Hexavalent Chromium (Cr-6)
• 1,4-Dioxane
• Stage 3 M/DBP Rule
• Potential Arsenic Rule (California)
Additional to the above regulations, Arcadis will work with the City to identify other water quality related issues that may be of operational concerns such as nitrification. Our team will identify improvements that will be required to meet water quality regulations or solve water quality issues, and provide estimated capital costs and annual O&M.

3I - Capital Improvement Program
Development
Any areas of low system performance as defined by the level of service criteria established for the system will be reviewed and improvements identified to bring those areas into desired performance. Various alternatives will be reviewed to identify the optimal improvements considering capital and operations impacts. All recommended improvements will be discussed in detail with the City.

The ultimate deliverable of a master plan project is a
concise, defensible, economical and implementable Capital Improvement Program (CIP). The CIP will include identified hydraulic and other improvements and incorporate other
projects identified by the City. Arcadis will work with the City to develop a prioritized CIP with a reasonable payback period.

Planning level capital costs will be developed for all identified projects using recent bid tabs, project budgets and contractor costs to calculate unit costs for replacement or rehabilitation.

If the information is not available, Arcadis will develop unit costs based on experience with similar projects in California and/ or manufacturer’s cost opinions.
3J. Domestic Water System Hydraulic Model
Training
Water distribution system analysis has grown increasingly complex as both hardware and software functionality has allowed operators, engineers and utility manager to ask new and different questions. Arcadis regularly performs training on distribution system theory, software use,
model functionality, system analysis, and model
maintenance.

Training of the City’s staff on the model will be critical for its ongoing use. This task will include preparation of training materials, a modeling manual, three full-day
hands-on training sessions (24-hours) on InfoWater
Software and the City’s model use for up to 6 City staff. A custom training agenda will be developed and provided
for input and review by the City prior to development of the training content. Training provided by Arcadis includes a variety of instructor-led presentations, hands-on model use via exercises, review of training documentation and manuals, and question and answer sessions.

Task 4 Sewer Main Video Inspection
The City desires to perform a closed-circuit television (CCTV) inspection of approximately 2,000 ft of sewer pipes to support the Sewer Master Plan.

Arcadis will contract with National Plant Services, Inc. (NPS) to perform the CCTV inspection. The intent is to inspect the pipe using CCTV equipment to examine and record the internal condition of the pipe. A camera will be driven or pulled through each section of pipe, and the operator will stop the camera to observe at any abnormality or defect spotted as well as note laterals and waterline marks. Each lateral, defect, or other abnormality will be classified and documented per NASSCO PACP standards.

NPS owns and operates fifteen (15) CCTV Inspection vehicles.

Each truck is equipped with two (2) cameras and repair parts.

NPS will use a data capture software, and use NASSCO PACP coding when performing inspections. All cameras used will be able to pan 360 degrees of the pipe and have a minimum resolution of 720 x 480. Cameras will have auto focus and zoom as well as sufficient lighting. National Plant Services will notify the City and Arcadis whenever the camera will not pass or finds an imminent pipe failure.

Our Quality Control team will take the maps provided the by Arcadis and develop an inspection schedule with milestones that ensure the City timeline is met. Data will be compiled and reviewed by our QA/QC team in the office on a weekly basis. They will make sure that the video is captured in the correct format, that all the defects are properly noted per NASSCO PACP standards, that the overlays display the correct information, and that a quality product is delivered. Any inspections that do not pass our Quality Control standards will be re-inspected at our cost.

After setting up traffic control, the area around the manhole will be checked with a gas monitor to assure there are not Task 4 Objective:
• To conduct CCTV inspection of sewer pipes as
necessary to support the Sewer Master Plan
Task 4 Meeting:
• Pre-inspection Meeting
• CCTV Results Review Meeting

appendix.
toxic fumes present. If the manhole was sealed prior to opening, it will be resealed when it is closed. The inspection will begin at the uppermost manhole of the segment to be recorded.

The camera will be inserted into the line and the required information will be input into the software with the appropriate overlay. The camera will travel down the line at a rate no greater than 30 feet per minute. Defects, laterals, etc. will be noted per PACP guidelines. The daily footage and locations can be relayed to the City’s field manager daily or as frequently as desired.

The Quality Control Department will then gather all the data and merge into one database. This database along with corresponding videos, pictures, and log sheets will be submitted.

Along with the data, a summary will be provided using log sheets detailing the inspection. Each line segment will be represented along with the footages of defects, laterals, etc.

An Excel sheet will be provided that has the line segments with their ‘Quickscore’ rating and can be sorted to show all the ‘5’s, ‘4’s, etc. This will assist the City with laying out future CIP projects and determining immediate needs.

Task 5 Manhole Flow Monitoring
The reliability of a sewer model is fundamentally dependent on the quality of data applied to its calibration. To streamline the program and provide cost-efficiency, we will assist the City in optimizing the flow monitoring program to maximize its benefit and identify monitoring locations most suitable for model calibration. Past flow monitoring locations will be discussed with the City to determine if these sites are suitable for the proposed monitoring effort. By utilizing past locations, comparisons can be made directly as to the impact of growth and/or conservation efforts.

Arcadis, in collaboration with V&A, will provide temporary sewer flow monitoring services at 20 monitoring locations for a minimum of 14 days. The flow monitoring program will be conducted concurrently with rainfall monitoring at two (2) locations. Depth and velocity data as well as rainfall data will be recorded at 5-minute intervals. Accurate and reproducible flow metering data are critical to all subsequent evaluations and form the basis for refining the model calibration.

The City has indicated that 20 sites are to be flow monitored, and Arcadis will collaborate with the City to confirm the site selections. The traditional criteria for flow monitoring locations include:
• Past monitoring sites (pros and cons of each site)
• Critical locations in the sewer system
• Isolate a specific land use or area of interest where possible
• Has no drop connections, backwater conditions, and
hydraulic jumps
• Easy to access and avoids high-risk traffic locations • Avoids redundancy with permanent flow monitoring
locations
Planning and preparing for data collection is equally
important as collecting the information. This task will include a flow and rainfall monitoring data collection plan laying the foundation for all aspects of field data collection activities.

The data collection plan will formalize the flow and rainfall monitoring for the overall collection system so that an optimized level of monitoring data is available. The plan will outline procedures for evaluating the monitoring data and qualifying if enough suitable data has been collected for model calibration purposes.

Task 5 Objective:
• To conduct sewer flow monitoring to obtain field
data for hydraulic model calibration.

Task 5 Meetings:
• Flow Monitoring Locations Selection Meeting
• Flow Monitoring Results Review Meeting
Task 5 Deliverables:
• As an appendix to the Sewer Master Plan,
the flow monitoring and rainfall effort will
be documented. The appendix will include a
description of each site, the data quality review
findings and a database containing the flow and
rainfall data.

Arcadis’ proven approach to reviewing flow data on a regular basis will be utilized to ensure quality data is collected and to flag any suspect data for prompt field investigation and correction. Data will be analyzed to confirm flow rates are reasonable compared to the water consumption data and that the depth and velocity data responds reasonably to rainfall data. Using Arcadis’ rainfall analysis tool, the captured rainfall events will quickly be processed to identify the magnitude of each storm and to evaluate the spatial variability as the storm event moves across the City. These tools and this approach to reviewing data and proactively identifying suspect readings will increase the City’s confidence in the calibrated model. At the conclusion of the master plan study, the flow monitoring effort will be summarized in the report and the data will be provided to the City.

Task 6 Preparation of Sewer Master Plan
6A. Executive Summary
Interpreting the recommendations and findings in the
Sewer Master Plan is critical for the City to ensure long term growth needs are met. Recognizing that the City’s
leadership and stakeholders need to be able to effectively and efficiently understand the Master Plan, Arcadis
proposes to deliver tools that are accessible and convey the impacts of the various Master Plan components. The
executive summary document and ESRI Story Maps with
dynamic results will be developed similar to those found in the Water Master Plan (Task 3).
6B. Sanitary Sewer System Description
The City’s sanitary sewer system is tributary to the Coastal Interceptor Sewer (CIS) which discharges to the City of Los Angeles’ Hyperion Wastewater Treatment Plant (HTP).

Flow is monitored at two, permanent metering stations
at the upstream (LA-1) and downstream end (SM-1) of the City’s connections to the CIS. Within the City, there are approximately 150 miles of sewers (both gravity and force mains) and over 2,800 manholes. The sewers range in size from 4 to 70 inches and consist of primarily vitrified clay pipe (VCP). The Moss Avenue Pump Station (MAPS) has a
capacity of 26 MGD and moves flow along the CIS.

The current sanitary sewer system configuration will be reviewed and updated to reflect system improvements
since the 2017 Sanitary Sewer System Master Plan
(developed by HDR). The operation of the MAPS will
also be confirmed to ensure the pumping scheme and
capacities are represented in the model.
6C. Historical and Current Sewage Flow Rate
Arcadis will use flow monitoring data (Task 5), available historic data, and data from the three monitoring stations to estimate dry weather flow by using EPA Sanitary Sewer Overflow Analysis and Planning (SSOAP) toolbox. The
estimated dry weather comprises base wastewater flow
Task 6 Objective:
• To update the City’s sewer flow generation rate
and hydraulic model

(BWF) with weekday and weekend diurnal patterns and
groundwater infiltration (GWI). The Average Dry Weather Flow (ADWF) and Peak Dry Weather flows (PDWF) will
be calculated for each flow monitor. The estimated dry
weather flow components will then be distributed to the parcels based on water consumption data in collaboration with Task 3. Flow from each parcel will then be allocated to the manhole closest to the parcel centrode. Care will be taken to evaluate BWF rates are reasonable given the population and sources of flow, and the GWI components
will be compared to industry standards to flag suspect
sources and data. If rainfall events occur during the flow monitoring period, the flow data will be decomposed to
identify the Rainfall Derived Inflow and Infiltration (RDII) component. Understanding the RDII will allow for the
peak flows to be extrapolated to Peak Wet Weather Flow
(PWWF) to represent the influence of wet weather. If the current flow monitoring effort does not capture any wet weather events, historical rainfall from past monitoring efforts will be used in conjunction with data from past monitors or the City’s permanent monitoring stations.

The peaking factors will also be compared with factors used by neighboring and similar sized systems. The estimated peaking factors will be applied to each sewershed in
addition to the dry weather flows in the model.
6D. Future Sewage Flow Rate
Although the City’s service area is fairly built out, the potential for additional growth along with continued
water conservations efforts will impact future flow rates.

A population based approach to flow development is
appropriate because of the following:
• Requires fewer flow meters than land use approach
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 36 • Is used widely in southern California
• Supports future projects using per capita flow to
estimate future flows for development, plans, or designs.

Arcadis will use the City’s planning data (e.g. redevelopment) along with population projections to estimate future flows within the service area for both
the near term (2025) and long term (2040) horizons. The projected water demands from the service area will also be used to truth check future wastewater flow from the
service area. ADWF, PDWF and PWWF will be developed
for each sewershed for both planning horizons.
6E. Update Sewer System Hydraulic Model
Arcadis proposes to use the City’s GIS data supplemented by record drawings to incorporate recent sewer
improvement projects into the existing InfoSewer model.

The data will also be processed using Arcadis’ Data Profiler tool to flag missing or suspect attributes (such as missing diameters or incompatible inverts). The model will include all major trunk sewers and tributary sewers (6-inches
and larger) owned by the City. Special attention will be given to confirming the configuration of the MAPS in the model, as well as the two monitoring stations. Ensuring these components are not only properly constructed in
the model but also that the operating rules are simulated correctly will drive the confidence in the model’s ability to mimic flow rates.
6F. Sewer System Hydraulic Model Calibration
and Analysis
In keeping with EPA guidance, Arcadis’ approach relies
primarily on graphical “goodness of fit” comparisons of model and monitored data to assess model calibration.

In addition, we provide suggested quantitative figures
for assessing model calibration. Close collaboration with the City’s Operations staff is essential to our approach to model calibration. Calibration will be comprised of dry and wet weather calibration.

The flow data will be loaded into the models and
simulation will be performed for the period in which flows are monitored. The model or simulated results will be
compared to the observed flow monitoring data.

E // 1.5 PROJECT WORK PLAN
Dry Weather Calibration
At the temporary monitoring locations and three
permanent monitoring, the model will be calibrated to dry weather flows, including weekend and weekday diurnal
patterns and base ground water. Arcadis will:
• Verify that the model is routing dry weather flows
correctly. Review system for possible connectivity
errors.
• Compare measured and modeled flow depths
adjusting Manning’s “n” as needed, or identifying the
cause of discrepancies.

Wet Weather Calibration
Wet weather calibration will depend on the storms that
occur during flow monitoring. If storms are captured during the flow monitoring, wet weather calibration will consist of:
• Storm events at the installed flow meters on a single event basis.
• Adjusting parameters to simulate the rainfall-induced flow response of the system for each storm event.
• Adjusting hydrologic parameters as needed to
generate volume and peak flow.
• Comparing peak flow, total volume and surcharge
depth to develop a robust planning tool for future flow projections and system analyses.

If no significant rain events are captured during the flow monitoring period, wet weather calibration will not be
performed. Peaking factors will be used for capacity
analysis after validation from the permanent flow
monitoring data.
6G. Capital Improvement Program
Development
The development of a feasible and affordable Capital
Improvement Program drives the City’s ability to
proactively manage future growth and the impacts of
changes in the sewer system’s need to convey flow. To
achieve this, the Level of Service (LOS) goals and preferred future projects must be identified.

Level of Service Goals
Level of Service (LOS) goals are necessary to define
acceptable conditions for the City under specified
situations. The acceptability may change based on location, size of pipe, and weather conditions. Arcadis will work with the City to either establish or review existing LOS criteria that will be used to trigger recommended improvements.

Capacity Assessment or Analysis of System Deficiencies
Once the LOS goals are established, the calibrated model will be used to evaluate the collection system’s response during dry and wet weather events for both existing
conditions, 2025 and 2040 conditions.

The following dynamic scenarios will be created for
As the City has an existing sewer
model, we anticipate the physical
network is well developed and
validated. The fee estimate only
reflects the effort to incorporate
recent sewer projects as scoped. Any
hydraulic conflicts in the existing
model may result in additional effort
and will be discussed with the City.

• Average Dry Weather Flows
• Peak Dry Weather Flows
• Peak Wet Weather Flows
The recommended CIP and the resulting master plan will
provide a defensible and feasible pathway for the City to implement over the next 20 years. Understanding that
cost is a significant driver in the CIP, Arcadis will use recent bid tabs, regional costing tools and manufacturer’s cost opinions to develop costs for each project. Prioritization of each project will be aligned with the City’s goals and potential Water system projects. The CIP will include
identified hydraulic and other improvements and
incorporate other projects identified by the City. The
ultimate goal is to develop a unified CIP that includes a holistic approach to manage the City’s water and sewer
systems.
6H. Sewer System Map Preparation
The sewer system evaluation maps and dashboards using
the ArcGIS Online and Arcadis’ ACE platform will also be utilized similar to the Domestic Water Master Plan (Task 3). Sewer model results with interactive maps will allow the City and Stakeholders the ability to see results outside of model software and will support collaboration of the capital improvement program with the entire project team. 6I. Sewer System Hydraulic Model Training
Arcadis intends to help the City become familiar with the hydraulic models from the vetting process onward and
help build its understanding of the software as the project develops. Our goal is for the City’s staff to have a comfort level before the hand off occurs. Arcadis will advise the City of any hardware, software, or licensing requirements necessary to efficiently use the model for future system analysis.

While in-person training sessions are preferred as the
trainer can better read the room and provide more
efficient coaching and support, Arcadis is prepared to
provide virtual training, in lieu of or in addition to the inperson training. We have training materials ready-to-go for Innovyze software and others that can be tailored to the City’s specific requirements. The training will cover sanitary sewer system theory, software use, model
functionality, system analysis, and model maintenance.

The three-day training will include a variety of instructorled presentations, hands-on model use exercises, review or training documentation and manuals, and Q&A sessions.

As an alternative, Arcadis will offer the option of “learn as we go” training to allow the City’s staff to be trained as each step in the modeling task is completed. This
approach distributes the training across the duration of the project and allows the trainees to learn in more frequent, but shorter sessions. We have successfully used both
approaches and will work with the City to determine the ideal training method for their staff.

Arcadis will develop a Model Reference Manual to
identify details of the model facilities, controls, and model assumptions for each model provided. The manual will also address maintenance by identifying components, such as
defining triggers for updates, who performs the updates, and specific process for performing the updates.

Arcadis can also assist the City to coordinate the purchase of new model software packages.

DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 40 Task 7.1 – Alternatives Development
Arcadis regularly implements a phased evaluation
approach with stakeholder engagement throughout
the process so that relevant potential alternatives are considered, the evaluation criteria and criteria weighting are well-defined and are supported by all stakeholders. The evaluations will be based on hydraulic simulations (for both water and sewer as necessary) to evaluate if any additional infrastructure is necessary, such as transmission mains, tank mixing systems, and impacts to any pump operations and energy. Workshops will be conducted with the City
and stakeholders led by our team of technical experts
to discuss and summarize the criteria and weighting,
identification of all potential alternatives and screening to feasible alternatives for further evaluation and selection.

While final alternatives will be
determined based on discussions
with the City, Task 7.1 currently plans
to evaluate three water treatment
scenarios. Arcadis will collaborate with
the City team to further develop the
water treatment scenarios that could
include:

1. New groundwater treatment plant
at the Santa Monica Airport

2. Seawater desalination facility that
utilizes existing, permitted seawater
extraction wells, and a new
desalinization treatment facility

3. Integration of new potable reuse
supplies from regional partners (e.g.,
LADWP Operation Next treated
water augmentation at the airport
and/or MWDSC Regional Recycled
Water Program)
An evaluation matrix will summarize all
options, criteria and weighting so that it
is transparent how the selection for the
optimal alternative was made, and the
decision tool will be a dynamic Microsoft
Excel-based tool that will allow the City
to modify weightings should conditions
change in the future without having to
purchase and learn new software. Our
team of technical experts understands
E // 1.5 PROJECT WORK PLAN
the likelihood of unintended consequences as well. We will provide input to consider unintended consequences as a
result of distribution system changes.

We understand that often the best option is a
combination of improvements that together make up a
wining alternative (for example, combining the new water treatment plant at the airport with transmission main
improvements that support changes in water conveyance).

This matrix will be used to identify which combined set of options is the best alternative for the City moving
forward in order to achieve regulatory acceptance while also providing the most cost-effective, timely and efficient means to do so.

Task 7.2 – Supplemental CCTV Inspection
Additional CCTV Inspection locations will be identified based on City input and/or on review of the existing system information in GIS. Ideally additional inspections should be identified during the kickoff meeting to minimize the mobilization efforts of the CCTV subconsultant. The CCTV inspections will follow the procedures and deliverables outlined in Task 4.
- Only high-level analysis for Scenario 3
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 41 E // 1.5 PROJECT WORK PLAN
Task 7.3 – Supplemental Sewer Flow Monitoring
The scoped two-week flow monitoring program in Task 5 may not capture enough dry weather flow data or any significant rainfall events to support model calibration. This supplemental task allows the City to extend the flow monitoring period in two week increments at a minimum of 10 sites. A longer sewer flow monitoring program presents a greater opportunity to capture multiple rainfall events and will increase confidence in the development of ADWF and PDWF values. During the initial siting discussions in Task 5, the City and Arcadis will identify the 5 highest priority sites (of the 20 sites) should the supplement sewer flow monitoring task be authorized. If, after reviewing the initial two weeks of data, the City determines that the supplemental sewer flow monitoring should be conducted at new sites, Arcadis will work with the City to identify ideal sites. As done in Task 5, the supplemental flow monitoring data will be reviewed and utilized to support the modeling in Task 6.

Task 7.4 – Value Added Services
The City is interested in additional services that add value beyond the base scope, but will further support and enhance the domestic water and sewer master plans. The following subtasks are described further in detail that also highlight their benefits to the City:
; 7.4.1 - Field Data Collection
; 7.4.2 - Risk-based Domestic Water Master Plan
; 7.4.3 - Risk-based Sewer Master Plan
; 7.4.4 - Concentrate (Brine) Evaluation
; 7.4.5 - AMI Technical Assistance

7.4.1 Field Data Collection
The domestic water model will be calibrated to verify hydraulic representations are accurate before using it for any analysis or decision-making during Task 3. However, depending on the level of accuracy required for informed decision making, and the amount of distribution system data available, an optional field data collection task should also be considered to support calibration efforts.

The Arcadis team consisting of water distribution system experts with backgrounds in distribution operations, planning and engineering understand the importance of accurate and reliable field data for calibration of hydraulic and water quality models. Arcadis regularly performs and trains utility personnel on proper hydrant operation, performing hydrant flushing and flow testing, performing pressure and flow monitoring, and proper sampling for water quality measurement.

A field data collection plan will be developed and reviewed by all necessary stakeholders to incorporate feedback for an effective and accurate field data collection effort. Based on our understanding of the City’s water distribution system, we propose the following efforts for field data collection to support model calibration:
ƒ Pressure survey:
ο Up to 10 temporary hydrant pressure recorders (Trimble HPR-31) installed for a period of 1 week during Summer 2022 with security covers and a common keyed lock with keys provided to the City. ο Arcadis owns and maintains a fleet of over 120 hydrant pressure recorders, so additional recorders or additional duration can be provided at an additional project cost if needed. ƒ Hydrant Flow Testing:
ο A quantity of up to 10 hydrant fire flow tests will be performed throughout the City ο Select locations may also be identified for pipe roughness (Hazen-Williams C-factor) flow tests concurrent with fire flow testing locations. These will be located strategically so that this test is performed simply with the addition of another pressure recorder to the fire flow test.

A four-phase workflow will be implemented to ensure the correct data (quantity and location) is collected, the correct procedure is executed, and the appropriate documentation is recorded and communicated. The workflow consists of: Identify, Prepare, Execute and Record. The Identify phase will implement a scientific approach to selecting the correct locations for sample collection and measurement and the Prepare phase will well-equip the field teams for understanding specific location details. The Execute phase will consist of Arcadis experts supported by City operators performing the testing. In the Record phase specific information regarding the test, equipment, and location will be collected using mobile tools. The Arcadis Team will closely coordinate with the City to develop a proposed field data collection plan for calibration which will be submitted for approval by the City.

DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 42 E // 1.5 PROJECT WORK PLAN
Proper data collection is critical to successful model calibration, and our team brings industry-leading subject matter expert in hydrant flow testing, including our task lead Ben Chenevey. Mr. Chenevey has performed water distribution system testing at nearly 400 different locations across the nation and regularly trains field crews, utilities, federal agencies, and other consultants in proper flow testing.

Key considerations include test placement, equipment accuracy, and confirming a sufficient decrease from static to residual pressure for the test to be considered valid. Our team uses dashboards and analytics developed by performing hundreds of flow tests across the US and globally to understand test and data validity. In the photo here, two ports on a single hydrant were opened to achieve sufficient pressure drop. This is important in selecting proper test locations as well, so that good quality data can be collected for model calibration, while also considering and minimizing the amount of non-revenue water that is flowed out of the system for model calibration.

7.4.2 Risk-based Domestic Water Master Plan
Effective asset management is a critical component of a water master plans. Asset management provides the risk-based framework by which rehab & replacement (R&R) and growth projects are prioritized, and capital and operations budgets are developed and managed. Arcadis is a national leader in asset management and assists our clients in developing asset management programs to meet long-term customer service level objectives and develop risk-based prioritization and funding programs. It is anticipated that this optional task will use a structured asset management framework to complete a desktop condition assessment and risk-based prioritization of projects to ultimately feed into the domestic water CIP and master plan developed in the main scope (Task 3). Arcadis is a national leader in asset management with the skills to assist our clients in developing ISO 55000 compliant asset management programs and applying IIMM standards to meet their financial, sustainability, reliability, and level of service goals. Our asset management service offerings include strategy development, business planning, infrastructure condition assessment and capital and O&M planning. Our Arcadis staff lead and serve on AWWA and WRF Asset Management Committees at the National and Local Levels. We have recently contributed to AWWA Manual M77 Condition Assessment of Water Mains and will bring that experience on desktop risk assessment to this project.

For the desktop pipeline condition assessment, the Arcadis team has a proven approach and existing Renewal and Replacement Planning System (RRPS) tool that can be leveraged to complete the assessment as well as support the overall risk analysis process for all domestic water system pipeline assets. For the pipelines, the approach begins with an analysis of age, materials, diameters and past break history to understand potential factors causing failures such as corrosive soils, high groundwater tables, pressure surges, etc. Cohorts, pipelines with similar behavior will be established and deterioration curves generated based on estimated useful life per cohort. capacity and other service level failures can be integrated into the analysis through GIS. A demo of the Arcadis RRPS tool as well as an overview of the approach will be discussed during the kickoff meeting, and City input will be incorporated into the final methodology.

Features of the RRPS Decision Support Tool
RRPS Function Description
Asset Inventory Accepts full asset inventory from GIS and CMMS with asset ID and attribute information.

Effective Useful Life Assigns EUL based on asset class with an unlimited number of classes and creates deterioration curves. Data tables have reference EULs from previous projects.

Condition Assessment Follows full IIMM best practices for physical and performance scoring using a 1-5 rating and customized category weighting.

Consequence of Failure Also follows IIM best practices, including triple bottom line consequence of failure evaluation and redundancy allowances if desired.

Cost Estimating Follows AACE Level 5 guidance
Rehabilitation vs Replace Considers rehabilitate versus replace based on risk, condition, location and EUL.

Project Definitions Assets are assigned to projects following a facility hierarchy, geography or programmatically by asset type, cost and risk.

CIP Scenarios Calculates system wide metrics for condition, risk and annual cost based on service level goals, set investment amounts or both.

DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 43 E // 1.5 PROJECT WORK PLAN
The Arcadis RRPS tool will be configured to evaluate the condition of the pipelines through a desktop analysis
leveraging the pipe attribute information available in
GIS, the past failure history from Cityworks or other files, interviews with knowledgeable staff and applying any
established service levels or industry standard decay
curves to determine what year replacement is required
to address physical condition. The outcomes from
hydraulic modeling will be incorporated in addition to staff interviews to score the other failure modes for the pipeline assets.

In addition to the likelihood of failure determined by
the desktop condition assessment, risk considers the
criticality or consequence of failure and the availability of redundancy to mitigate failure impacts. The risk scores normalize the evaluation and provide for an “apples
to-apples” comparison to prioritize projects for assets of different types and functions. The criticality criteria will be developed for the pipeline assets following the triple bottom line principal, which incorporates the economic, social and environmental impacts of a failure. Arcadis will provide examples of consequence scoring from similar
planning projects, including California utilities, to assist the City in developing the optimum scoring approach. Applying the scoring standards developed through collaboration
with the City, the Arcadis team will work to score asset criticality and risk. It is anticipated that all pipeline assets will be scored using GIS queries; the RRPS tool accepts input from this process and will calculate the overall risk score considering redundancy.

Based upon the pipeline asset condition and risk score
results, the domestic water master plan (Task 3) will be expanded with additional logical projects that are created and evaluated using the RRPS tool. For pipeline assets, the pipelines will be grouped by risk score, replacement year, and geography to identify specific pipes requiring replacement due to growth and condition. A workshop
will be held with the City to review the major alternatives evaluated for pipelines to review annual funding needs
for various service level scenarios to select the best fit for the City balancing funding, condition, and risk objectives.

The RRPS tool will be used to prepare the scenarios and for review with the City. Comments from the City will be incorporated into the final alternatives selections. Not only will these risk-based results and capital improvements
be incorporated into a more complete domestic water
master plan, but they can also subsequently be used
for asset management program work in the future.

7.4.3 Risk-based Sewer Master Plan
Effective asset management is also a critical component of a sewer master plans. Asset management provides the
risk-based framework by which rehab & replacement and
growth projects are prioritized, and capital and operations budgets are developed and managed. It is anticipated that this optional task will use a structured asset management framework to complete a desktop condition assessment
and risk-based prioritization of projects to ultimately feed into the sewer CIP and master plan developed in the main scope (Task 6). The same approach detailed in Optional
Task 7.4.2 (Risk-based Domestic Water Master Plan) will be followed with the sewer system to develop risk evaluations of all sewer mains.

For this desktop sewer main condition assessment, the
Arcadis team has a proven approach and existing Renewal and Replacement Planning System (RRPS) tool that can be leveraged to complete the assessment as well as support the overall risk analysis process for all sewer system
pipeline assets. Based upon the sewer main asset condition and risk score results, the sewer master plan (Task 6) will be expanded with additional logical projects that are
created and evaluated using the RRPS tool. Not only will these risk-based results and capital improvements
be incorporated into a more complete sewer master
plan, but they can also subsequently be used for asset
management program work in the future.

7.4.4 Concentrate (Brine) Evaluation
As a component of the City’s multifaceted effort to
become water-independent, it is expanding the production of water resources via potable reuse and brackish
groundwater desalination, both of which utilize reverse osmosis (RO) and generate a concentrate residuals stream.

The new RO systems at the SMURRF and AWTF will add
concentrate discharge flows to the sewer system, as will the expansion of the Arcadia WTP. However, because the
SMURRF treats both stormwater and coastal aquifer flows, while the AWTF purifies recycled wastewater – all with
concentrate water quality disparate from each other and the Arcadia WTP concentrate – these new RO systems will change the quality of the blended wastewater supplies.

Moreover, the additional concentrate from all three RO
systems will increase the percent contribution of more
saline supplies comprising the City’s wastewater, likewise altering the water quality. The additional concentrate flow will be somewhat moderated by the incorporation of Flow Reversal RO technology at the Arcadia facility to increase recovery, although the higher recovery will also intensify the concentrate quality.

Further compounding the combined concentrate (and
blended wastewater) quality variation, the SMURRF source water will fluctuate with stormwater flows, thus altering the quality of its brine intermittently, and the brackish groundwater supply treated at SMURRF is anticipated to
become more saline in future years. As a result, for the purposes of comprehensive planning, it is important
for the City to fully understand the impact of these
changes on both the quantity and quality of the
concentrate flows and their influence on collected
wastewater.

In assisting the City with this effort, Arcadis will first characterize the projected changes to the City’s sewer
flow – both quality and quantity – including the anticipated variability based on known SMURRF source water supply
boundary conditions and water quality data collected
under implementation of the SWIP. The potential impact
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 44 of increased groundwater salinization in the SMURRF
source water will also be evaluated. This fully characterized profile of the future concentrate / blended sewer flows will be compared to current sewer flows and quality
to understand the pending changes and assess the
potential for impact on the City’s discharge permits and/ or agreements with LA Sanitation & Environment (LASAN)
which receives the City’s wastewater at the Hyperion
Water Reclamation Plant.

Due to the known presence of PFAS in both the City
stormwater and sewer flows, Arcadis will also assess the potential for regulatory action under the Clean Water
Act (CWA), the Resource Conservation and Recovery Act
(RCRA), and the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) to affect
discharges (e.g., numerical limits, treatment, industrial pretreatment programs, etc.). This assessment will also examine potential alternatives for the management of RO concentrate and/or combined wastewater flows that may
be necessary as result of such regulatory action. A detailed technical memorandum will be generated to capture this
comprehensive concentrate evaluation, which may be
incorporated into the Master Plan Updates, at the City’s discretion.

7.4.5 AMI Technical Assistance
Project Understanding
Arcadis understands that the City has piloted three AMI systems over the last several years and is now ready to move forward with a full procurement and implementation for approximately 18,400 meters. We know this will be a turnkey project of a cellular AMI system implemented over the next two years. Our experienced AMI experts offer
services that will ensure the successful implementation of your AMI project and exploit it to achieve broader
goals. Our staff possesses deep technical and managerial experience in areas such as metering, customer service, engineering, information technology, and business
consulting. Arcadis’ role as Owner’s agent will streamline your implementation efforts and reduce overall project
risks. The following six areas described below provides detail on the consulting services we recommend for the
City’s AMI project. Arcadis is flexible to scope a project that meets your needs while achieving the key targeted
outcomes of the project.
“We can help the City meet its goals of
improving meter reading efficiency, move to
monthly billing, engage customers with water
usage and conservation efforts and validate
these efforts, as well as minimize water loss
through non-revenue water initiatives.”
1) System Selection Consulting and Contract
Negotiations
With the City’s release of an AMI System solicitation,
Arcadis can support the City’s evaluation team with the understanding of technical capabilities and proposed
pricing. We will provide clarity and explanation to support understanding of the responses, as well as a perform
a lifecycle pricing comparison to support the team’s
selection process. After vendor selection, Arcadis will provide AMI expertise to support the City with the contract development and contract negotiations. A strong contract is an important tool to manage risks that are inherent in an AMI project. Our experienced practitioners have negotiated multiple AMI contracts that cover all project elements.

E // 1.5 PROJECT WORK PLAN
Our efforts will result in a contract that is favorable to the City, specifically in areas such as:
3 product warranties and remedies
3 excessive failure warranties
3 system performance

2) Program and Project Management
Our role is owner’s agent for the City throughout the AMI project. Our project management services include items
such as schedule management, scope management
and change control, resource management, project risk
management, project documentation maintenance, and
conducting status meetings and developing status reports. 3) Public Outreach Support and Customer
Communication
The AMI system implementation effort will require
targeted and consistent communication to inform
stakeholders, excite them about the benefits, and garner their support for the transition to an AMI system. Arcadis typically recommends that a customer communication
program be initiated early in the project, starting with the development of a communication plan. To develop the
communication plan, our team will perform the following activities:
; Communication Planning Workshop. We will facilitate
a workshop with the City project team members
and Public Information Office stakeholders to gain
consensus among the decision makers about an
appropriate communication strategy. The outcome will
be the development of a Communications Plan.
; Communication Plan Development. We will draft a
communication plan which includes the key strategies,
tactics, and communications management. These
customer communications strategies will be aligned

7.4.6 Sewer Model Conversion
Scope of Work
The City currently uses Innovyze InfoSewer model to perform hydraulic analyses of its sanitary sewer system. The simulation of sewer system in the existing InfoSewer model is unsatisfactory and Innovyze is discontinuing InfoSewer software in the 2023-24 timeframe. The City is exploring alternatives to its existing software as part of the Sewer Master Plan Update effort. Arcadis has preliminarily recommended three feasible sewer system software alternatives including PCSWMM, Innovyze ICM and SewerGEMS for City’s consideration. The existing InfoSewer model must be converted to a compatible format for the selected software. The Scope of Work is structured to provide smooth transition from existing InfoSewer model to City selected software model.

Task 1- Sewer Model Conversion
Arcadis will convert the City’s existing InfoSewer sewer network model to the selected software model.

The task comprises of following steps:
 Determination of scenario and sewer networks
The existing InfoSewer model has 7 scenarios and respective sewer networks and loadings.

Arcadis will work with the City to determine the necessary scenarios and sewer networks for the project.
 Sewer network export
Arcadis will export the sewer network for each scenario from the existing InfoSewer model. The model export might be in the form of shapefiles or direct export to other software if compatible.  Processing of the exported format
Based on the software that the city selects, Arcadis will convert the exported sewer network to compatible format for import. This format might be InfoSWMM format or shapefiles depending on the selected software.
 Import of the sewer network
Arcadis will import the sewer network for all the scenario to the selected software.  Sewer network comparison
Once the import is complete, Arcadis will review and compare the imported model with the existing InfoSewer model to ensure model components and scenario were correctly imported.

Assumptions:
 City will provide complete sewer network model and related data as requested by Arcadis.

Deliverables:
 Model Conversion review meeting and meeting notes
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 This Scope of Work is structured to provide the City with SSMP compliance support services for the following tasks:

 Compliance gaps identified in the Draft 2022 SSMP not considered to fully address 2006 WDR and 2013 MRP requirements
 Recommendations for addressing compliance gaps at a minimum and for improving compliance with requirements associated with identified gaps, as warranted.

A draft review summary memorandum will be provided for review and comment by the City. Consultant will host a one-hour review meeting to address City comments and/or concerns; one final memorandum will be submitted that address comments as discussed in the review meeting.

Assumptions:
 City will provide a complete draft of the 2022 SSMP and associated records, as requested by the Consultant; gaps in content and/or records will be listed as compliance gaps unavailable for review in the summary memorandum.
 Anticipated schedule: 3 months from NTP
Deliverables:
 Kickoff meeting agenda and meeting minutes
 2022 Draft SSMP Review Summary Memorandum (one copy in word and PDF format)  Memorandum review meeting and meeting minutes
 2022 Final SSMP Review Summary Memorandum (one copy in word and PDF format) Task 2 – SSO Record Keeping Review
Consultant, in coordination with the City, will select up to six sewer overflow events between January 2020 and September 2022 for documentation compliance with CIWQS certified reports and record keeping requirements. Consultant will compare City event documentation files with certified event reports and current City OERP/WQMP record keeping requirements.

Consultant will identify areas of deficiencies, potential concern, strengths, and recommended improvements for the City to consider associated with current emergency response documentation.

This information will be documented in a record keeping summary memorandum. A draft review summary memorandum will be provided for review and comment by the City. Consultant will host a one-hour review meeting to address City comments and/or concerns; one final memorandum will be submitted that address comments as discussed in the review meeting.

3B. Domestic Water System
Description
The domestic water system will be
reviewed to accurately understand
and document all facilities, capacities,
and processes, as well as a developing
complete representation of the existing
domestic water distribution system.

The City’s domestic water system has
four sources entering the distribution
system: two MWD feeder services,
Santa Monica Well 1, and the Arcadia
Water Treatment Plant. Both MWD
connections are 24” diameter and can
maintain a hydraulic grade capable of
direct service to all three pressure zones
within the City’s service area. Typically,
the distribution system demand is
served between 30 - 40% through
these MWD connections, and the rest
is supplied from City owned ground
water wells. Multiple reservoirs are also
connected to the distribution system
including Riviera Reservoir, Mt Olivette
Reservoir, and San Vicente Reservoir. Figure 7. Potable Water System Map from 2020 Urban Water Management Plan 3C. Historical and Current Water Use
The City’s water consumption has dropped in recent
years due largely to conservation efforts by the City
across the customer base. Declines in consumption also
can result in additional water quality challenges due to localized areas of increased water age. Reviewing historical consumption data to identify trends in consumption based on location and customer class will be important for better understanding the future direction of water use. We will work with our partner Maddaus, who is currently looking at water use data as part of the conservation plan, to review finished water production for the entire system, pressure zone flows, and residential, commercial, and industrial customer metered usage. The difference between
production and billed usage will be used to determine
non-revenue water, which will also be broken out for each pressure zone. Minimal non-revenue water has historically been observed by the City (1.6% in 2016 and negative in more recent years – like due to metering inaccuracies), so calculated values will be corroborated with other reports and the City’s experiences to use the best estimate for modeling.

Once base demands are established, demand scaling
factors must be identified to extrapolate demands
allocated to each customer meter location to project
average, maximum daily, and peak hourly system flow
conditions unique to each pressure zone and customer
class. Our deep technical knowledge of modeling, demand forecasting and planning will ensure the results of this task provide realistic and practical factors throughout each hour of the day.

Seasonal, daily and hourly demands vary from
community to community based on variables, such as
climate, climate change, customer types, and areas of
irrigation based on economic factors. It is important that appropriate demand peaking factors be selected so that
water system improvements are not unduly oversized,
thus increasing costs and creating water quality concerns.

Our technical experts will work with the City to review the data to determine appropriate factors to use for each pressure zone while considering the impacts on systemwide peak demands.

Diurnal patterns reflect the varying usage of water
throughout a typical day and are important for
understanding not only the impact of peak demand
conditions on the performance of the distribution system, but also the impact of low demand periods on water
quality, which allows the City to better understand these and simulate improvements to address any challenges.

Representative demand patterns will be developed
for each pressure zone based on flow data and water
balances for each area.

In addition to average, max, and peak demand conditions, maximum day demand plus fire flow (MDD+FF) will
also be developed. One of the primary factors in sizing, operating and designing water distribution infrastructure is meeting specific capacity requirements to provide
adequate fire suppression. Various guidance manuals are relied on to support this, including AWWA M32, AWWA
M17, and NFPA 291, but many systems establish general
required fire flow guidelines depending on the customer type or land use type. Based on our team’s industry
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 29 E // 1.5 PROJECT WORK PLAN
expertise, and through coordination with the City, the correct MDD+FF demand will be identified for use during model development and system evaluations. This way the most appropriate fire suppression guidelines will be applied when sizing future capital improvements.
3D. Future Water Use
Modeling future demand projections is a critical component of recommending any improvements or changes to a water distribution system. This task will build off the Water Conservation Master Plan currently being developed by Maddaus.

Near term (2025) and far term (2040) planning horizons for future demands will be considered; demand projections under multiple future planning years will assist with prioritizing and sequencing recommended improvements projects for ECWA.

Based on the latest Urban Water Master Plan, demands may see an overall slight increase or relatively flat demand through 2040 due to balances of new developments and conservation efforts. Demand forecasts from this and other studies, along with information directly from the City, will be incorporated into final values by land use and pressure zone. This will also be combined with future development information like the recently adopted 6th Housing Elements.

Future demands will be allocated
in the model and maintained in
a logical scenario and alternative
hierarchy in the modeling
software. Future demands will
be differentiated from existing
demands using different demand
categories, different named
demand patterns (e.g., “20-year
Future Residential Demand
Pattern”), and appropriately
named scenarios, data sets,
and alternatives. The purpose
of careful naming conventions
for future demands is to assist
the various users of the model
in easily differentiating between
existing and future demands in
the model. Whereas existing
modeled demands are based on
detailed water billing information
and geospatial locating of water
customers, sets of assumptions,
estimations, and trend data are
incorporated into future demands.
3E - Current and Future Water Supply
Current and future water supply for the City will be analyzed such that they may be incorporated into the modeling and master planning effort. Based on the 2018 Sustainable Water Master Plan Update & 2020 Urban Water Management Plans, ground water makes up around 65% of the current potable water supply while the rest is imported from MWD connections.

Ground water currently comes from the Charnock, Olympic, Arcadia sub-basins through multiple ground water wells owned by the City. Arcadia Water Treatment Plant treats much of this ground water before discharging into the water distribution system. Limited recycled water is also utilized by the City through the Santa Monica Urban Runoff Recycling Facility; this flow currently makes up around 1% of the total water supply.

In the future, the City wants to increase groundwater utilization and reduce imported water. Groundwater increases are planned through a combination of Olympic well field restoration, groundwater recharging efforts, and Arcadia WTP expansion and enhancements. The City also anticipates an increase in non-potable recycled water use that may also help offset imported water usage. The City desires to have the first direct potable reuse (DPR) application in CA where water from the new AWTF would be distributed to customers, depending on future finalized DPR regulations. The City is also considering brand new water sources including new wells near the airport, and the option to consider desalination in the future; these may be considered and analyzed further in optional Task 7.1.

3F. Update Domestic Water System Hydraulic Model
Model updates consist of accurate representation
of system infrastructure, applying updated demand
allocation, factors and patterns, and matching model
reactions to changing conditions such as pump starts
and stops to recent SCADA system data. The purpose of
this task is to bring the model up-to-date with current conditions within the system and bring the model to a
level of detail aligned with current industry trends. This will be accomplished by the Arcadis team with a mindset for
future use of the model and allow for easy of long-term model maintenance by the City.

Following a review of the GIS database, any necessary
revisions to model pipes will be performed in collaboration with the City. The current industry trend is for modeled pipes to have a one-to-one relationship with the associated GIS database.

Arcadis has developed multiple tools to allow for a
seamless GIS-model interoperability, as well as ongoing improvements available in the existing built-in tools within InfoWater modeling software. We will develop a clear and concise process to maintain this GIS integration and make sure appropriate updates are passed to the respective
systems. Any tools necessary to do this will be provided to the City for long-term model maintenance.
3G. Domestic Water System Hydraulic Model Calibration and Analysis visualize the calibration results at multiple locations and for multiple scenarios.

2. Similarly, we have developed computer scripts which
directly read the InfoWater database of comparison of
multiple scenarios within the model. This visualization of comparison provides an efficient means to
understand the impact of any changes during
calibration from adjustment to adjustment.

3. We will work closely with City staff during the
calibration process to understand any anomalies and
develop solutions. In consultation with City staff, we
will use a macro and a micro calibration approach for
the model calibration. During workshops and progress
meetings, we will collaboratively develop a set of
criteria for macro and micro calibration. For example,
Figure 9. Examples of model connectivity challenges that need resolved during model updates Examples of quality assurance and adjustments of
horizontal piping assets that are common include:
• Topology, connectivity, disconnected pipes, parallel
pipes, and intersecting pipes
• Nodes in close proximity, disconnected nodes, pipesplit candidates • Hydrants and hydrant laterals (their inclusion,
representation, connectivity, and model attributes)
• Diameter discrepancies and model representation with
facility boundaries
Examples of model updates to vertical assets such as
pumps, tanks, and valves, include the following and any other updates deemed necessary through the model
calibration effort:
• Confirm pump simulations align with the recent pump
test data and perform any necessary updates
• Confirm valve position and settings align with available operational data
• Where possible, headloss curves may be added to
better represent remotely controlled positioning valves • All control valves (such as Pressure Reducing Valves) will be reviewed for correct sizes, configuration, and
settings.

Model calibration is believed by the water industry to be the most technically challenging aspect of modeling (per a survey by the AWWA Engineering Modeling Applications
Committee). We bring a proven approach and unique
tools that will accelerate the model calibration process.

Blending our depth of calibration experience with innovative approaches proposed specifically for this project, we feel our plan offers efficient and effective methods resulting in an exceptional model of the City water distribution system.

Our approach consists of the following calibration tools:

1. Our team has developed computer scripts to directly
read the InfoWater database and bring results into
Microsoft Excel and PowerBI for automated comparison
of calibration data. This, along with calibration SCADA templates developed by our team, will make it easy to
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 31 E // 1.5 PROJECT WORK PLAN
the criteria could be that pressure at a node is within 4 pounds per square-inch (psi) of the measured data. During macro calibration parameters like pressure zone diurnal curves and demand at a node can be adjusted to match model pressures to field observed data. Alternatively, during micro calibration parameters like pipe roughness factors will be adjusted to match model results to observed data. City staff will be updated and consulted with before and after any major updates.

Available SCADA and hydrant testing data from the City will be utilized for model calibration to represent conditions for at least a 24-hour time period. An option to extend the project to include field data collection (Task 7) is also included which would supplement the City’s available data with additional pressure and hydrant flow data; this would improve data available and thus may improve calibration results. The measure of model calibration is the primary tool to communicate the level of confidence and representativeness of the model computer simulations to the actual system. Common measures define a threshold allowable variation for each measurement or as percentage variance.

However, every system has facilities which are more critical for the model than others. Prior to model calibration, the Arcadis Team will conduct a workshop with City staff to define an innovative measurement of calibration, considering multiple factors such as shape of a curve, difference in actual values, and importance of facilities.

Figure 10. Hydraulic Model Calibration Process Schematic. Documenting the complete process is important to our team so that the City modelers and staff can reference this in the future, and for confidence and buy-in of model calibration and capabilities.

Once the model calibration is complete, we will create necessary scenarios and data sets within the model for existing system conditions, future system conditions/demands, and various system evaluations. Master plans require a number of model scenarios to be developed under a variety of demand conditions. The Arcadis team is highly experienced with creating organized hierarchical structures for dozens (and even hundreds) of model runs. We know and understand the importance of setting scenarios up correctly the first time and making sure that the structure is flexible to accommodate additional scenarios in a logical framework.

To support the City’s management of its water system, Arcadis will identify system performance level of service requirements. These level of service requirements typically consist of acceptable thresholds for pressure, velocity, headloss gradient, tank turnover, water age, and water quality concentrations. Any areas of low system performance as defined by the level of service criteria established for the system will be reviewed with the City to help collaborate on system improvements that will be included in the CIP.

Arcadis also places emphasis on providing an exceptional customer experience for our projects. For this project, in addition to paper maps for results presentation throughout the project, we propose to offer results presentation through interactive online map and Analytic and Collaboration Environment (ACE) dashboards hosted within ESRI’s ArcGIS Online . This will allow the City and Stakeholders the ability to see interactive model results outside of model software, customized to a specific login. While paper maps are a great tool to visualize systemwide model output, the use of these online dashboards with interactive maps allow the user to zoom, select a specific pipe or node and see detailed results.

This will be used by the project team throughout execution to collaborate and see specific model status and results; these will be available for one month following final project deliverables and can also be transferred to the City for continued use.

Figure 11. Arcadis’s Analytics & Collaboration Environment (ACE). In addition to paper maps, model results throughout the project will be communicated to the City through ACE which allows the City to understand model output through an interactive platform and to select and see model output for any individual asset. 3H. Water Quality Regulations Analysis
Water quality regulatory landscape continue to evolve at the national and state levels. Regulations affecting water systems continue to become more stringent. Arcadis’ water quality experts will assist the City to navigate and stay proactive. There are several key regulatory actions that could impact the City’s operations and maintenance through the planning horizon. Based on our understanding of the City’s system, the ones to focus on are 1,4-dioxane. The City currently treats for 1,4-dioxane and VOCs at Arcadia WTP. A progressive design build project to address 1,4-dioxane is also underway at Arcadia WTP.

Although unlikely to affect the drinking water system, per- and polyfluoroalkyl substances (PFAS) has been detected in the City stormwater and sewer flows feeding SMURRF so potential PFAS related regulations are another to keep track of. As an optional value-added service (see Task 7.4.4), Arcadis proposes to assess the potential for regulatory action under the Clean Water Act (CWA) and other regulations to affect discharges and examine potential alternatives for the management of RO concentrate and/or combined wastewater flows.

For this Task 3H, Arcadis will track the following regulations with the focus on 1,4-dioxane. • Third Six-Year Review
• Fourth Unregulated Contaminant Monitoring Rule (UCMR4) • Fifth Unregulated Contaminant Monitoring Rule (UCMR5) • Lead and Copper Rule Revisions
• Potential Per- and Polyfluoroalkyl Substances (PFAS) related regulations • Hexavalent Chromium (Cr-6)
• 1,4-Dioxane
• Stage 3 M/DBP Rule
• Potential Arsenic Rule (California)
Additional to the above regulations, Arcadis will work with the City to identify other water quality related issues that may be of operational concerns such as nitrification. Our team will identify improvements that will be required to meet water quality regulations or solve water quality issues, and provide estimated capital costs and annual O&M.

3I - Capital Improvement Program
Development
Any areas of low system performance as defined by the level of service criteria established for the system will be reviewed and improvements identified to bring those areas into desired performance. Various alternatives will be reviewed to identify the optimal improvements considering capital and operations impacts. All recommended improvements will be discussed in detail with the City.

The ultimate deliverable of a master plan project is a
concise, defensible, economical and implementable Capital Improvement Program (CIP). The CIP will include identified hydraulic and other improvements and incorporate other
projects identified by the City. Arcadis will work with the City to develop a prioritized CIP with a reasonable payback period.

Planning level capital costs will be developed for all identified projects using recent bid tabs, project budgets and contractor costs to calculate unit costs for replacement or rehabilitation.

If the information is not available, Arcadis will develop unit costs based on experience with similar projects in California and/ or manufacturer’s cost opinions.
3J. Domestic Water System Hydraulic Model
Training
Water distribution system analysis has grown increasingly complex as both hardware and software functionality has allowed operators, engineers and utility manager to ask new and different questions. Arcadis regularly performs training on distribution system theory, software use,
model functionality, system analysis, and model
maintenance.

Training of the City’s staff on the model will be critical for its ongoing use. This task will include preparation of training materials, a modeling manual, three full-day
hands-on training sessions (24-hours) on InfoWater
Software and the City’s model use for up to 6 City staff. A custom training agenda will be developed and provided
for input and review by the City prior to development of the training content. Training provided by Arcadis includes a variety of instructor-led presentations, hands-on model use via exercises, review of training documentation and manuals, and question and answer sessions.

Task 4 Sewer Main Video Inspection
The City desires to perform a closed-circuit television (CCTV) inspection of approximately 2,000 ft of sewer pipes to support the Sewer Master Plan.

Arcadis will contract with National Plant Services, Inc. (NPS) to perform the CCTV inspection. The intent is to inspect the pipe using CCTV equipment to examine and record the internal condition of the pipe. A camera will be driven or pulled through each section of pipe, and the operator will stop the camera to observe at any abnormality or defect spotted as well as note laterals and waterline marks. Each lateral, defect, or other abnormality will be classified and documented per NASSCO PACP standards.

NPS owns and operates fifteen (15) CCTV Inspection vehicles.

Each truck is equipped with two (2) cameras and repair parts.

NPS will use a data capture software, and use NASSCO PACP coding when performing inspections. All cameras used will be able to pan 360 degrees of the pipe and have a minimum resolution of 720 x 480. Cameras will have auto focus and zoom as well as sufficient lighting. National Plant Services will notify the City and Arcadis whenever the camera will not pass or finds an imminent pipe failure.

Our Quality Control team will take the maps provided the by Arcadis and develop an inspection schedule with milestones that ensure the City timeline is met. Data will be compiled and reviewed by our QA/QC team in the office on a weekly basis. They will make sure that the video is captured in the correct format, that all the defects are properly noted per NASSCO PACP standards, that the overlays display the correct information, and that a quality product is delivered. Any inspections that do not pass our Quality Control standards will be re-inspected at our cost.

After setting up traffic control, the area around the manhole will be checked with a gas monitor to assure there are not Task 4 Objective:
• To conduct CCTV inspection of sewer pipes as
necessary to support the Sewer Master Plan

toxic fumes present. If the manhole was sealed prior to opening, it will be resealed when it is closed. The inspection will begin at the uppermost manhole of the segment to be recorded.

The camera will be inserted into the line and the required information will be input into the software with the appropriate overlay. The camera will travel down the line at a rate no greater than 30 feet per minute. Defects, laterals, etc. will be noted per PACP guidelines. The daily footage and locations can be relayed to the City’s field manager daily or as frequently as desired.

The Quality Control Department will then gather all the data and merge into one database. This database along with corresponding videos, pictures, and log sheets will be submitted.

Along with the data, a summary will be provided using log sheets detailing the inspection. Each line segment will be represented along with the footages of defects, laterals, etc.

An Excel sheet will be provided that has the line segments with their ‘Quickscore’ rating and can be sorted to show all the ‘5’s, ‘4’s, etc. This will assist the City with laying out future CIP projects and determining immediate needs.

Task 5 Manhole Flow Monitoring
The reliability of a sewer model is fundamentally dependent on the quality of data applied to its calibration. To streamline the program and provide cost-efficiency, we will assist the City in optimizing the flow monitoring program to maximize its benefit and identify monitoring locations most suitable for model calibration. Past flow monitoring locations will be discussed with the City to determine if these sites are suitable for the proposed monitoring effort. By utilizing past locations, comparisons can be made directly as to the impact of growth and/or conservation efforts.

Arcadis, in collaboration with V&A, will provide temporary sewer flow monitoring services at 20 monitoring locations for a minimum of 14 days. The flow monitoring program will be conducted concurrently with rainfall monitoring at two (2) locations. Depth and velocity data as well as rainfall data will be recorded at 5-minute intervals. Accurate and reproducible flow metering data are critical to all subsequent evaluations and form the basis for refining the model calibration.

The City has indicated that 20 sites are to be flow monitored, and Arcadis will collaborate with the City to confirm the site selections. The traditional criteria for flow monitoring locations include:
• Past monitoring sites (pros and cons of each site)
• Critical locations in the sewer system
• Isolate a specific land use or area of interest where possible
• Has no drop connections, backwater conditions, and
hydraulic jumps
• Easy to access and avoids high-risk traffic locations • Avoids redundancy with permanent flow monitoring
locations
Planning and preparing for data collection is equally
important as collecting the information. This task will include a flow and rainfall monitoring data collection plan laying the foundation for all aspects of field data collection activities.

The data collection plan will formalize the flow and rainfall monitoring for the overall collection system so that an optimized level of monitoring data is available. The plan will outline procedures for evaluating the monitoring data and qualifying if enough suitable data has been collected for model calibration purposes.

Task 5 Objective:
• To conduct sewer flow monitoring to obtain field
data for hydraulic model calibration.

Task 5 Meetings:
• Flow Monitoring Locations Selection Meeting
• Flow Monitoring Results Review Meeting
Task 5 Deliverables:
• As an appendix to the Sewer Master Plan,
the flow monitoring and rainfall effort will
be documented. The appendix will include a
description of each site, the data quality review
findings and a database containing the flow and
rainfall data.

Arcadis’ proven approach to reviewing flow data on a regular basis will be utilized to ensure quality data is collected and to flag any suspect data for prompt field investigation and correction. Data will be analyzed to confirm flow rates are reasonable compared to the water consumption data and that the depth and velocity data responds reasonably to rainfall data. Using Arcadis’ rainfall analysis tool, the captured rainfall events will quickly be processed to identify the magnitude of each storm and to evaluate the spatial variability as the storm event moves across the City. These tools and this approach to reviewing data and proactively identifying suspect readings will increase the City’s confidence in the calibrated model. At the conclusion of the master plan study, the flow monitoring effort will be summarized in the report and the data will be provided to the City.

Task 6 Preparation of Sewer Master Plan
6A. Executive Summary
Interpreting the recommendations and findings in the
Sewer Master Plan is critical for the City to ensure long term growth needs are met. Recognizing that the City’s
leadership and stakeholders need to be able to effectively and efficiently understand the Master Plan, Arcadis
proposes to deliver tools that are accessible and convey the impacts of the various Master Plan components. The
executive summary document and ESRI Story Maps with
dynamic results will be developed similar to those found in the Water Master Plan (Task 3).
6B. Sanitary Sewer System Description
The City’s sanitary sewer system is tributary to the Coastal Interceptor Sewer (CIS) which discharges to the City of Los Angeles’ Hyperion Wastewater Treatment Plant (HTP).

Flow is monitored at two, permanent metering stations
at the upstream (LA-1) and downstream end (SM-1) of the City’s connections to the CIS. Within the City, there are approximately 150 miles of sewers (both gravity and force mains) and over 2,800 manholes. The sewers range in size from 4 to 70 inches and consist of primarily vitrified clay pipe (VCP). The Moss Avenue Pump Station (MAPS) has a
capacity of 26 MGD and moves flow along the CIS.

The current sanitary sewer system configuration will be reviewed and updated to reflect system improvements
since the 2017 Sanitary Sewer System Master Plan
(developed by HDR). The operation of the MAPS will
also be confirmed to ensure the pumping scheme and
capacities are represented in the model.
6C. Historical and Current Sewage Flow Rate
Arcadis will use flow monitoring data (Task 5), available historic data, and data from the three monitoring stations to estimate dry weather flow by using EPA Sanitary Sewer Overflow Analysis and Planning (SSOAP) toolbox. The
estimated dry weather comprises base wastewater flow

(BWF) with weekday and weekend diurnal patterns and
groundwater infiltration (GWI). The Average Dry Weather Flow (ADWF) and Peak Dry Weather flows (PDWF) will
be calculated for each flow monitor. The estimated dry
weather flow components will then be distributed to the parcels based on water consumption data in collaboration with Task 3. Flow from each parcel will then be allocated to the manhole closest to the parcel centrode. Care will be taken to evaluate BWF rates are reasonable given the population and sources of flow, and the GWI components
will be compared to industry standards to flag suspect
sources and data. If rainfall events occur during the flow monitoring period, the flow data will be decomposed to
identify the Rainfall Derived Inflow and Infiltration (RDII) component. Understanding the RDII will allow for the
peak flows to be extrapolated to Peak Wet Weather Flow
(PWWF) to represent the influence of wet weather. If the current flow monitoring effort does not capture any wet weather events, historical rainfall from past monitoring efforts will be used in conjunction with data from past monitors or the City’s permanent monitoring stations.

The peaking factors will also be compared with factors used by neighboring and similar sized systems. The estimated peaking factors will be applied to each sewershed in
addition to the dry weather flows in the model.
6D. Future Sewage Flow Rate
Although the City’s service area is fairly built out, the potential for additional growth along with continued
water conservations efforts will impact future flow rates.

A population based approach to flow development is
appropriate because of the following:
• Requires fewer flow meters than land use approach
DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 10538908 City of Santa Monica // 2022 Domestic Water & Sanitary Sewer Master Plan Updates // 36 • Is used widely in southern California
• Supports future projects using per capita flow to
estimate future flows for development, plans, or designs.

Arcadis will use the City’s planning data (e.g. redevelopment) along with population projections to estimate future flows within the service area for both
the near term (2025) and long term (2040) horizons. The projected water demands from the service area will also be used to truth check future wastewater flow from the
service area. ADWF, PDWF and PWWF will be developed
for each sewershed for both planning horizons.
6E. Update Sewer System Hydraulic Model
Arcadis proposes to use the City’s GIS data supplemented by record drawings to incorporate recent sewer
improvement projects into the existing InfoSewer model.

The data will also be processed using Arcadis’ Data Profiler tool to flag missing or suspect attributes (such as missing diameters or incompatible inverts). The model will include all major trunk sewers and tributary sewers (6-inches
and larger) owned by the City. Special attention will be given to confirming the configuration of the MAPS in the model, as well as the two monitoring stations. Ensuring these components are not only properly constructed in
the model but also that the operating rules are simulated correctly will drive the confidence in the model’s ability to mimic flow rates.
6F. Sewer System Hydraulic Model Calibration
and Analysis
In keeping with EPA guidance, Arcadis’ approach relies
primarily on graphical “goodness of fit” comparisons of model and monitored data to assess model calibration.

In addition, we provide suggested quantitative figures
for assessing model calibration. Close collaboration with the City’s Operations staff is essential to our approach to model calibration. Calibration will be comprised of dry and wet weather calibration.

The flow data will be loaded into the models and
simulation will be performed for the period in which flows are monitored. The model or simulated results will be
compared to the observed flow monitoring data.

E // 1.5 PROJECT WORK PLAN
Dry Weather Calibration
At the temporary monitoring locations and three
permanent monitoring, the model will be calibrated to dry weather flows, including weekend and weekday diurnal
patterns and base ground water. Arcadis will:
• Verify that the model is routing dry weather flows
correctly. Review system for possible connectivity
errors.
• Compare measured and modeled flow depths
adjusting Manning’s “n” as needed, or identifying the
cause of discrepancies.

Wet Weather Calibration
Wet weather calibration will depend on the storms that
occur during flow monitoring. If storms are captured during the flow monitoring, wet weather calibration will consist of:
• Storm events at the installed flow meters on a single event basis.
• Adjusting parameters to simulate the rainfall-induced flow response of the system for each storm event.
• Adjusting hydrologic parameters as needed to
generate volume and peak flow.
• Comparing peak flow, total volume and surcharge
depth to develop a robust planning tool for future flow projections and system analyses.

If no significant rain events are captured during the flow monitoring period, wet weather calibration will not be
performed. Peaking factors will be used for capacity
analysis after validation from the permanent flow
monitoring data.
6G. Capital Improvement Program
Development
The development of a feasible and affordable Capital
Improvement Program drives the City’s ability to
proactively manage future growth and the impacts of
changes in the sewer system’s need to convey flow. To
achieve this, the Level of Service (LOS) goals and preferred future projects must be identified.

Level of Service Goals
Level of Service (LOS) goals are necessary to define
acceptable conditions for the City under specified
situations. The acceptability may change based on location, size of pipe, and weather conditions. Arcadis will work with the City to either establish or review existing LOS criteria that will be used to trigger recommended improvements.

Capacity Assessment or Analysis of System Deficiencies
Once the LOS goals are established, the calibrated model will be used to evaluate the collection system’s response during dry and wet weather events for both existing
conditions, 2025 and 2040 conditions.

The following dynamic scenarios will be created for
As the City has an existing sewer
model, we anticipate the physical
network is well developed and
validated. The fee estimate only
reflects the effort to incorporate
recent sewer projects as scoped. Any
hydraulic conflicts in the existing
model may result in additional effort
and will be discussed with the City.

• Average Dry Weather Flows
• Peak Dry Weather Flows
• Peak Wet Weather Flows
The recommended CIP and the resulting master plan will
provide a defensible and feasible pathway for the City to implement over the next 20 years. Understanding that
cost is a significant driver in the CIP, Arcadis will use recent bid tabs, regional costing tools and manufacturer’s cost opinions to develop costs for each project. Prioritization of each project will be aligned with the City’s goals and potential Water system projects. The CIP will include
identified hydraulic and other improvements and
incorporate other projects identified by the City. The
ultimate goal is to develop a unified CIP that includes a holistic approach to manage the City’s water and sewer
systems.
6H. Sewer System Map Preparation
The sewer system evaluation maps and dashboards using
the ArcGIS Online and Arcadis’ ACE platform will also be utilized similar to the Domestic Water Master Plan (Task 3). Sewer model results with interactive maps will allow the City and Stakeholders the ability to see results outside of model software and will support collaboration of the capital improvement program with the entire project team. 6I. Sewer System Hydraulic Model Training
Arcadis intends to help the City become familiar with the hydraulic models from the vetting process onward and
help build its understanding of the software as the project develops. Our goal is for the City’s staff to have a comfort level before the hand off occurs. Arcadis will advise the City of any hardware, software, or licensing requirements necessary to efficiently use the model for future system analysis.

While in-person training sessions are preferred as the
trainer can better read the room and provide more
efficient coaching and support, Arcadis is prepared to
provide virtual training, in lieu of or in addition to the inperson training. We have training materials ready-to-go for Innovyze software and others that can be tailored to the City’s specific requirements. The training will cover sanitary sewer system theory, software use, model
functionality, system analysis, and model maintenance.

The three-day training will include a variety of instructorled presentations, hands-on model use exercises, review or training documentation and manuals, and Q&A sessions.

As an alternative, Arcadis will offer the option of “learn as we go” training to allow the City’s staff to be trained as each step in the modeling task is completed. This
approach distributes the training across the duration of the project and allows the trainees to learn in more frequent, but shorter sessions. We have successfully used both
approaches and will work with the City to determine the ideal training method for their staff.

Arcadis will develop a Model Reference Manual to
identify details of the model facilities, controls, and model assumptions for each model provided. The manual will also address maintenance by identifying components, such as
defining triggers for updates, who performs the updates, and specific process for performing the updates.

Arcadis can also assist the City to coordinate the purchase of new model software packages.

Arcadis regularly implements a phased evaluation
approach with stakeholder engagement throughout
the process so that relevant potential alternatives are considered, the evaluation criteria and criteria weighting are well-defined and are supported by all stakeholders. The evaluations will be based on hydraulic simulations (for both water and sewer as necessary) to evaluate if any additional infrastructure is necessary, such as transmission mains, tank mixing systems, and impacts to any pump operations and energy. Workshops will be conducted with the City
and stakeholders led by our team of technical experts
to discuss and summarize the criteria and weighting,
identification of all potential alternatives and screening to feasible alternatives for further evaluation and selection.

While final alternatives will be
determined based on discussions
with the City, Task 7.1 currently plans
to evaluate three water treatment
scenarios. Arcadis will collaborate with
the City team to further develop the
water treatment scenarios that could
include:

1. New groundwater treatment plant
at the Santa Monica Airport

2. Seawater desalination facility that
utilizes existing, permitted seawater
extraction wells, and a new
desalinization treatment facility

3. Integration of new potable reuse
supplies from regional partners (e.g.,
LADWP Operation Next treated
water augmentation at the airport
and/or MWDSC Regional Recycled
Water Program)
An evaluation matrix will summarize all
options, criteria and weighting so that it
is transparent how the selection for the
optimal alternative was made, and the
decision tool will be a dynamic Microsoft
Excel-based tool that will allow the City
to modify weightings should conditions
change in the future without having to
purchase and learn new software. Our
team of technical experts understands
E // 1.5 PROJECT WORK PLAN
the likelihood of unintended consequences as well. We will provide input to consider unintended consequences as a
result of distribution system changes.

We understand that often the best option is a
combination of improvements that together make up a
wining alternative (for example, combining the new water treatment plant at the airport with transmission main
improvements that support changes in water conveyance).

This matrix will be used to identify which combined set of options is the best alternative for the City moving
forward in order to achieve regulatory acceptance while also providing the most cost-effective, timely and efficient means to do so.

Task 7.2 – Supplemental CCTV Inspection
Additional CCTV Inspection locations will be identified based on City input and/or on review of the existing system information in GIS. Ideally additional inspections should be identified during the kickoff meeting to minimize the mobilization efforts of the CCTV subconsultant. The CCTV inspections will follow the procedures and deliverables outlined in Task 4.

Task 7.3 – Supplemental Sewer Flow Monitoring
The scoped two-week flow monitoring program in Task 5 may not capture enough dry weather flow data or any significant rainfall events to support model calibration. This supplemental task allows the City to extend the flow monitoring period in two week increments at a minimum of 10 sites. A longer sewer flow monitoring program presents a greater opportunity to capture multiple rainfall events and will increase confidence in the development of ADWF and PDWF values. During the initial siting discussions in Task 5, the City and Arcadis will identify the 5 highest priority sites (of the 20 sites) should the supplement sewer flow monitoring task be authorized. If, after reviewing the initial two weeks of data, the City determines that the supplemental sewer flow monitoring should be conducted at new sites, Arcadis will work with the City to identify ideal sites. As done in Task 5, the supplemental flow monitoring data will be reviewed and utilized to support the modeling in Task 6.

Task 7.4 – Value Added Services
The City is interested in additional services that add value beyond the base scope, but will further support and enhance the domestic water and sewer master plans. The following subtasks are described further in detail that also highlight their benefits to the City:
; 7.4.1 - Field Data Collection
; 7.4.2 - Risk-based Domestic Water Master Plan
; 7.4.3 - Risk-based Sewer Master Plan
; 7.4.4 - Concentrate (Brine) Evaluation
; 7.4.5 - AMI Technical Assistance

7.4.1 Field Data Collection
The domestic water model will be calibrated to verify hydraulic representations are accurate before using it for any analysis or decision-making during Task 3. However, depending on the level of accuracy required for informed decision making, and the amount of distribution system data available, an optional field data collection task should also be considered to support calibration efforts.

The Arcadis team consisting of water distribution system experts with backgrounds in distribution operations, planning and engineering understand the importance of accurate and reliable field data for calibration of hydraulic and water quality models. Arcadis regularly performs and trains utility personnel on proper hydrant operation, performing hydrant flushing and flow testing, performing pressure and flow monitoring, and proper sampling for water quality measurement.

A field data collection plan will be developed and reviewed by all necessary stakeholders to incorporate feedback for an effective and accurate field data collection effort. Based on our understanding of the City’s water distribution system, we propose the following efforts for field data collection to support model calibration:
ƒ Pressure survey:
ο Up to 10 temporary hydrant pressure recorders (Trimble HPR-31) installed for a period of 1 week during Summer 2022 with security covers and a common keyed lock with keys provided to the City. ο Arcadis owns and maintains a fleet of over 120 hydrant pressure recorders, so additional recorders or additional duration can be provided at an additional project cost if needed. ƒ Hydrant Flow Testing:
ο A quantity of up to 10 hydrant fire flow tests will be performed throughout the City ο Select locations may also be identified for pipe roughness (Hazen-Williams C-factor) flow tests concurrent with fire flow testing locations. These will be located strategically so that this test is performed simply with the addition of another pressure recorder to the fire flow test.

A four-phase workflow will be implemented to ensure the correct data (quantity and location) is collected, the correct procedure is executed, and the appropriate documentation is recorded and communicated. The workflow consists of: Identify, Prepare, Execute and Record. The Identify phase will implement a scientific approach to selecting the correct locations for sample collection and measurement and the Prepare phase will well-equip the field teams for understanding specific location details. The Execute phase will consist of Arcadis experts supported by City operators performing the testing. In the Record phase specific information regarding the test, equipment, and location will be collected using mobile tools. The Arcadis Team will closely coordinate with the City to develop a proposed field data collection plan for calibration which will be submitted for approval by the City.

Proper data collection is critical to successful model calibration, and our team brings industry-leading subject matter expert in hydrant flow testing, including our task lead Ben Chenevey. Mr. Chenevey has performed water distribution system testing at nearly 400 different locations across the nation and regularly trains field crews, utilities, federal agencies, and other consultants in proper flow testing.

Key considerations include test placement, equipment accuracy, and confirming a sufficient decrease from static to residual pressure for the test to be considered valid. Our team uses dashboards and analytics developed by performing hundreds of flow tests across the US and globally to understand test and data validity. In the photo here, two ports on a single hydrant were opened to achieve sufficient pressure drop. This is important in selecting proper test locations as well, so that good quality data can be collected for model calibration, while also considering and minimizing the amount of non-revenue water that is flowed out of the system for model calibration.

7.4.2 Risk-based Domestic Water Master Plan
Effective asset management is a critical component of a water master plans. Asset management provides the risk-based framework by which rehab & replacement (R&R) and growth projects are prioritized, and capital and operations budgets are developed and managed. Arcadis is a national leader in asset management and assists our clients in developing asset management programs to meet long-term customer service level objectives and develop risk-based prioritization and funding programs. It is anticipated that this optional task will use a structured asset management framework to complete a desktop condition assessment and risk-based prioritization of projects to ultimately feed into the domestic water CIP and master plan developed in the main scope (Task 3). Arcadis is a national leader in asset management with the skills to assist our clients in developing ISO 55000 compliant asset management programs and applying IIMM standards to meet their financial, sustainability, reliability, and level of service goals. Our asset management service offerings include strategy development, business planning, infrastructure condition assessment and capital and O&M planning. Our Arcadis staff lead and serve on AWWA and WRF Asset Management Committees at the National and Local Levels. We have recently contributed to AWWA Manual M77 Condition Assessment of Water Mains and will bring that experience on desktop risk assessment to this project.

For the desktop pipeline condition assessment, the Arcadis team has a proven approach and existing Renewal and Replacement Planning System (RRPS) tool that can be leveraged to complete the assessment as well as support the overall risk analysis process for all domestic water system pipeline assets. For the pipelines, the approach begins with an analysis of age, materials, diameters and past break history to understand potential factors causing failures such as corrosive soils, high groundwater tables, pressure surges, etc. Cohorts, pipelines with similar behavior will be established and deterioration curves generated based on estimated useful life per cohort. capacity and other service level failures can be integrated into the analysis through GIS. A demo of the Arcadis RRPS tool as well as an overview of the approach will be discussed during the kickoff meeting, and City input will be incorporated into the final methodology.

Features of the RRPS Decision Support Tool
RRPS Function Description
Asset Inventory Accepts full asset inventory from GIS and CMMS with asset ID and attribute information.

Effective Useful Life Assigns EUL based on asset class with an unlimited number of classes and creates deterioration curves. Data tables have reference EULs from previous projects.

Condition Assessment Follows full IIMM best practices for physical and performance scoring using a 1-5 rating and customized category weighting.

Consequence of Failure Also follows IIM best practices, including triple bottom line consequence of failure evaluation and redundancy allowances if desired.

Cost Estimating Follows AACE Level 5 guidance
Rehabilitation vs Replace Considers rehabilitate versus replace based on risk, condition, location and EUL.

Project Definitions Assets are assigned to projects following a facility hierarchy, geography or programmatically by asset type, cost and risk.

CIP Scenarios Calculates system wide metrics for condition, risk and annual cost based on service level goals, set investment amounts or both.

The Arcadis RRPS tool will be configured to evaluate the condition of the pipelines through a desktop analysis
leveraging the pipe attribute information available in
GIS, the past failure history from Cityworks or other files, interviews with knowledgeable staff and applying any
established service levels or industry standard decay
curves to determine what year replacement is required
to address physical condition. The outcomes from
hydraulic modeling will be incorporated in addition to staff interviews to score the other failure modes for the pipeline assets.

In addition to the likelihood of failure determined by
the desktop condition assessment, risk considers the
criticality or consequence of failure and the availability of redundancy to mitigate failure impacts. The risk scores normalize the evaluation and provide for an “apples
to-apples” comparison to prioritize projects for assets of different types and functions. The criticality criteria will be developed for the pipeline assets following the triple bottom line principal, which incorporates the economic, social and environmental impacts of a failure. Arcadis will provide examples of consequence scoring from similar
planning projects, including California utilities, to assist the City in developing the optimum scoring approach. Applying the scoring standards developed through collaboration
with the City, the Arcadis team will work to score asset criticality and risk. It is anticipated that all pipeline assets will be scored using GIS queries; the RRPS tool accepts input from this process and will calculate the overall risk score considering redundancy.

Based upon the pipeline asset condition and risk score
results, the domestic water master plan (Task 3) will be expanded with additional logical projects that are created and evaluated using the RRPS tool. For pipeline assets, the pipelines will be grouped by risk score, replacement year, and geography to identify specific pipes requiring replacement due to growth and condition. A workshop
will be held with the City to review the major alternatives evaluated for pipelines to review annual funding needs
for various service level scenarios to select the best fit for the City balancing funding, condition, and risk objectives.

The RRPS tool will be used to prepare the scenarios and for review with the City. Comments from the City will be incorporated into the final alternatives selections. Not only will these risk-based results and capital improvements
be incorporated into a more complete domestic water
master plan, but they can also subsequently be used
for asset management program work in the future.

7.4.3 Risk-based Sewer Master Plan
Effective asset management is also a critical component of a sewer master plans. Asset management provides the
risk-based framework by which rehab & replacement and
growth projects are prioritized, and capital and operations budgets are developed and managed. It is anticipated that this optional task will use a structured asset management framework to complete a desktop condition assessment
and risk-based prioritization of projects to ultimately feed into the sewer CIP and master plan developed in the main scope (Task 6). The same approach detailed in Optional
Task 7.4.2 (Risk-based Domestic Water Master Plan) will be followed with the sewer system to develop risk evaluations of all sewer mains.

For this desktop sewer main condition assessment, the
Arcadis team has a proven approach and existing Renewal and Replacement Planning System (RRPS) tool that can be leveraged to complete the assessment as well as support the overall risk analysis process for all sewer system
pipeline assets. Based upon the sewer main asset condition and risk score results, the sewer master plan (Task 6) will be expanded with additional logical projects that are
created and evaluated using the RRPS tool. Not only will these risk-based results and capital improvements
be incorporated into a more complete sewer master
plan, but they can also subsequently be used for asset
management program work in the future.

7.4.4 Concentrate (Brine) Evaluation
As a component of the City’s multifaceted effort to
become water-independent, it is expanding the production of water resources via potable reuse and brackish
groundwater desalination, both of which utilize reverse osmosis (RO) and generate a concentrate residuals stream.

The new RO systems at the SMURRF and AWTF will add
concentrate discharge flows to the sewer system, as will the expansion of the Arcadia WTP. However, because the
SMURRF treats both stormwater and coastal aquifer flows, while the AWTF purifies recycled wastewater – all with
concentrate water quality disparate from each other and the Arcadia WTP concentrate – these new RO systems will change the quality of the blended wastewater supplies.

Moreover, the additional concentrate from all three RO
systems will increase the percent contribution of more
saline supplies comprising the City’s wastewater, likewise altering the water quality. The additional concentrate flow will be somewhat moderated by the incorporation of Flow Reversal RO technology at the Arcadia facility to increase recovery, although the higher recovery will also intensify the concentrate quality.

Further compounding the combined concentrate (and
blended wastewater) quality variation, the SMURRF source water will fluctuate with stormwater flows, thus altering the quality of its brine intermittently, and the brackish groundwater supply treated at SMURRF is anticipated to
become more saline in future years. As a result, for the purposes of comprehensive planning, it is important
for the City to fully understand the impact of these
changes on both the quantity and quality of the
concentrate flows and their influence on collected
wastewater.

In assisting the City with this effort, Arcadis will first characterize the projected changes to the City’s sewer
flow – both quality and quantity – including the anticipated variability based on known SMURRF source water supply
boundary conditions and water quality data collected
under implementation of the SWIP. The potential impact

source water will also be evaluated. This fully characterized profile of the future concentrate / blended sewer flows will be compared to current sewer flows and quality
to understand the pending changes and assess the
potential for impact on the City’s discharge permits and/ or agreements with LA Sanitation & Environment (LASAN)
which receives the City’s wastewater at the Hyperion
Water Reclamation Plant.

Due to the known presence of PFAS in both the City
stormwater and sewer flows, Arcadis will also assess the potential for regulatory action under the Clean Water
Act (CWA), the Resource Conservation and Recovery Act
(RCRA), and the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) to affect
discharges (e.g., numerical limits, treatment, industrial pretreatment programs, etc.). This assessment will also examine potential alternatives for the management of RO concentrate and/or combined wastewater flows that may
be necessary as result of such regulatory action. A detailed technical memorandum will be generated to capture this
comprehensive concentrate evaluation, which may be
incorporated into the Master Plan Updates, at the City’s discretion.

7.4.5 AMI Technical Assistance
Project Understanding
Arcadis understands that the City has piloted three AMI systems over the last several years and is now ready to move forward with a full procurement and implementation for approximately 18,400 meters. We know this will be a turnkey project of a cellular AMI system implemented over the next two years. Our experienced AMI experts offer
services that will ensure the successful implementation of your AMI project and exploit it to achieve broader
goals. Our staff possesses deep technical and managerial experience in areas such as metering, customer service, engineering, information technology, and business
consulting. Arcadis’ role as Owner’s agent will streamline your implementation efforts and reduce overall project
risks. The following six areas described below provides detail on the consulting services we recommend for the
City’s AMI project. Arcadis is flexible to scope a project that meets your needs while achieving the key targeted
outcomes of the project.
“We can help the City meet its goals of
improving meter reading efficiency, move to
monthly billing, engage customers with water
usage and conservation efforts and validate
these efforts, as well as minimize water loss
through non-revenue water initiatives.”
1) System Selection Consulting and Contract
Negotiations
With the City’s release of an AMI System solicitation,
Arcadis can support the City’s evaluation team with the understanding of technical capabilities and proposed
pricing. We will provide clarity and explanation to support understanding of the responses, as well as a perform
a lifecycle pricing comparison to support the team’s
selection process. After vendor selection, Arcadis will provide AMI expertise to support the City with the contract development and contract negotiations. A strong contract is an important tool to manage risks that are inherent in an AMI project. Our experienced practitioners have negotiated multiple AMI contracts that cover all project elements.

E // 1.5 PROJECT WORK PLAN
Our efforts will result in a contract that is favorable to the City, specifically in areas such as:
3 product warranties and remedies
3 excessive failure warranties
3 system performance
3 service levels
2) Program and Project Management
Our role is owner’s agent for the City throughout the AMI project. Our project management services include items
such as schedule management, scope management
and change control, resource management, project risk
management, project documentation maintenance, and
conducting status meetings and developing status reports. 3) Public Outreach Support and Customer
Communication
The AMI system implementation effort will require
targeted and consistent communication to inform
stakeholders, excite them about the benefits, and garner their support for the transition to an AMI system. Arcadis typically recommends that a customer communication
program be initiated early in the project, starting with the development of a communication plan. To develop the
communication plan, our team will perform the following activities:
; Communication Planning Workshop. We will facilitate
a workshop with the City project team members
and Public Information Office stakeholders to gain
consensus among the decision makers about an
appropriate communication strategy. The outcome will
be the development of a Communications Plan.
; Communication Plan Development. We will draft a
communication plan which includes the key strategies,
tactics, and communications management. These
customer communications strategies will be aligned
with the project timeline.

Task 3 – System Acceptance Planning
Arcadis will work with the City and the vendors to develop a testing strategy and approach that will define the test phases to be performed, the level of testing within each phase, the test data strategy, testing environments, testing tools, testing procedures and the sign-off process. The plan will also describe the process by which the testing results will be reported and communicated to the broader project team.

The required testing phases for the project will be defined in the plan, which will include:
 End-to-End Integration Testing
o Objective. Integrated system testing verifies that all application components are working as a complete solution rather than merely in isolation. This includes testing all system interfaces, such as meter installation, meter reading and billing operations. Goal is to confirm the integration is passing data from the endpoint to the utility system accurately and per specification.
o When. This testing will begin after AMI software has passed AMI headend confirmation testing, integration development is complete, and a specified number of AMI enabled endpoints are installed.
o Responsible Party. Integration testing is performed by the AMI vendor and CIS vendor. Arcadis will provide facilitation and oversight.  User Acceptance Testing
o Objective. User acceptance testing confirms the functionality and capabilities by use case are working as expected.
o When. This testing will begin after integration testing is completed and accepted, and when an agreed upon number of AMI endpoints are installed.

DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 DocuSign Envelope ID: D940A0DF-4128-4831-9C25-2183562C1776 o Responsible Party. This testing is led by the City (and is a great training opportunity).

Arcadis will provide facilitation and oversight.
 System Acceptance
o Objective. System acceptance confirms the AMI end-to-end system performance meets the agreed upon acceptance criteria.
o When. This evaluation begins at the conclusion of user acceptance testing and is monitored until the evaluation timeframe has concluded. o Responsible Party. This evaluation is led by the City. Arcadis will provide oversight and technical guidance. Issue resolution may be required by AMI vendor, installation contractor, or CIS vendor.
o NOTE: The framework for system acceptance testing will be used again during final system acceptance testing.

The Arcadis team will support the City on the software testing processes, which should include the following:
 Test Script Design, Planning and Tracking. The Arcadis testing team will provide technical advice to the City team throughout the design, planning and testing process.

7.4.6 Sewer Model Conversion
Scope of Work
The City currently uses Innovyze InfoSewer model to perform hydraulic analyses of its sanitary sewer system. The simulation of sewer system in the existing InfoSewer model is unsatisfactory and Innovyze is discontinuing InfoSewer software in the 2023-24 timeframe. The City is exploring alternatives to its existing software as part of the Sewer Master Plan Update effort. Arcadis has preliminarily recommended three feasible sewer system software alternatives including PCSWMM, Innovyze ICM and SewerGEMS for City’s consideration. The existing InfoSewer model must be converted to a compatible format for the selected software. The Scope of Work is structured to provide smooth transition from existing InfoSewer model to City selected software model.

Task 1- Sewer Model Conversion
Arcadis will convert the City’s existing InfoSewer sewer network model to the selected software model.

The task comprises of following steps:
 Determination of scenario and sewer networks
The existing InfoSewer model has 7 scenarios and respective sewer networks and loadings.

Arcadis will work with the City to determine the necessary scenarios and sewer networks for the project.
 Sewer network export
Arcadis will export the sewer network for each scenario from the existing InfoSewer model. The model export might be in the form of shapefiles or direct export to other software if compatible.  Processing of the exported format
Based on the software that the city selects, Arcadis will convert the exported sewer network to compatible format for import. This format might be InfoSWMM format or shapefiles depending on the selected software.
 Import of the sewer network
Arcadis will import the sewer network for all the scenario to the selected software.  Sewer network comparison
Once the import is complete, Arcadis will review and compare the imported model with the existing InfoSewer model to ensure model components and scenario were correctly imported.

Assumptions:
 City will provide complete sewer network model and related data as requested by Arcadis.

Deliverables:
 Model Conversion review meeting and meeting notes

 Task 1 Review of 2022 Draft SSMP for Compliance
 Task 2 SSO Record Keeping Review
In addition, the following two optional tasks for SSMP compliance support services are included in this scope of work for future consideration by the City:
 Task 3 Review Support for SSMP Revisions (Adoption of New WDR) (Optional Services for Future Consideration)
 Task 4 Training and Exercises (Optional Services for Future Consideration) Task 1 – Review of 2022 Draft SSMP for Compliance
Consultant will host a one-hour SSMP Compliance Review Kickoff meeting with the City to discuss scope, schedule, and current documents and records required for completing a compliance review of the 2022 Draft SSMP with applicable regulatory requirements.

Consultant will complete a review of the most current SSMP (2022 draft version in progress) for compliance with 2006 WDR and 2013 MRP requirements. Consultant will produce a review summary memorandum with a brief list of key findings and concerns for the following:
 Compliance gaps identified in the Draft 2022 SSMP not considered to fully address 2006 WDR and 2013 MRP requirements
 Recommendations for addressing compliance gaps at a minimum and for improving compliance with requirements associated with identified gaps, as warranted.

A draft review summary memorandum will be provided for review and comment by the City. Consultant will host a one-hour review meeting to address City comments and/or concerns; one final memorandum will be submitted that address comments as discussed in the review meeting.

Assumptions:
 City will provide a complete draft of the 2022 SSMP and associated records, as requested by the Consultant; gaps in content and/or records will be listed as compliance gaps unavailable for review in the summary memorandum.
 Anticipated schedule: 3 months from NTP
Deliverables:
 Kickoff meeting agenda and meeting minutes
 2022 Draft SSMP Review Summary Memorandum (one copy in word and PDF format)  Memorandum review meeting and meeting minutes
