TASK 300 — FLOW MONITORING
This Task will conduct and evaluate flow monitoring to allow accurate estimates of existing and future system
flows so that the City can adequately plan to accommodate its future sewer needs. This task will include flow
monitoring of up to seven (7) locations by a Subconsultant. This task will be documented in TM No.2—Flow
Monitoring that will be included as an Appendix of the Plan. The task includes the following activities:
TA,SK3OOA[T|V|T|ES
301. Review and Update Sewer Service Area and Basins. Review existing sewer service area and basins based on
changes to parcels, collection system piping, and laterals information. It is anticipated the City will provide updated
information electronically. Update Sewer Basins and provide an updated map for City review and confirmation.
302. Identify Primary Collectors and Lift Stations. The City will identify primary collectors and lift stations for
potential flow monitoring and inclusion in the hydraulic model (Task 600). It is anticipated the collectors will be
"skeletonized" to only include pipes greater than 12-inch and 8-inch pipes needed to represent flow conditions from
sewer basins. To assist with future tasks, the City will need to provide invert elevations for the selected primary
collectors and information onLift Stations.
303. Identify Flow Monitoring Locations. Identify recommended locations in install temporary flow monitoring
devices in the gravity system at up five (5) locations to measure primary collectors and or Lift Stations south of I-
40S.Anadditiona|two(Z)flovvmonitorsnnphmarycoUectorsor|iftstationsvviUbeaddednorthnf|'4O5,as
directed by the City. Flow monitoring locations will be provided to the City to confirm their suitability for meter
installation.
3U4'Flow Monitoring ADS will provide temporary flmwmonitornguepvicesto[onsultanttocoUatthee(])
months of flow data up to seven (7). After completion of the monitoring, ADS will provide a Rain Dependent
Inflow & Infiltration (RDI/1) Analysis and an electronic report. The work will be performed in three phases as set
forth below:
a. Phase|-YNobi|ization
u' Site Locations ADS will work with the Consultant and the City toidentify/verify the seven h1
locations for monitor installations. Upon approval by the City, additional locations may be added per
the optional costs inthe budget.
a. Site Inve»tigation ' Once the installation sites are provided toADS, ADS field cevv(s)will perform
site investigations. ADS will utilize astandard two (z) person field crew for fieldwork and comply
with Federal standards for confined -space entry. The proposed flow monitoring location will be
located, inspected, and verified for hydraulic suitability. ADS will also check for debris inthe
manhole that could impact data quality and coordinate any required cleaning efforts with the City.
62
ADS field crews will look for evidence and signs oferratic flow patterns. ADS will also investigate
adjacent manholes inorder tuidentify the best monitoring locations.
I Site Reports Site reports will be generated upon completion of the site investigations. The site
reports will include a sketch of the general location, physical characteristics and diameters of the
proposed monitoring locations, manhole depths, flow measurements, and other comments
pertinent tuthe location such asany special traffic o/safety issues. Final site locations tobe
approved bvthe Consultant.
4. Equipment -ADS will utilize wireless ADS@ Model Triton+ T11 flow monitors during the course of this
project. Atypical monitor installation will include anultrasonic deothsenso/thatviUbemoontedat
the invert of the pipe, a redundant pressure depth sensor; and a Doppler velocity sensor also
mounted atornear the invert.
Monitor Activation Once installed, the monitor will beactivated and set totake readings at5-
minute intervals. ADS Field crews will take manual depth readings with a ruler and velocity readings
with a portable, instantaneous velocity meter in order to confirm the monitor is collecting accurate
data based onthe actual existing hydraulic conditions ateach location.
b. PhaseU Flow Monitoring
�. Flow Monitoring Once the monitors are installed and verified tobeinworking order, ADS will
monitor for a period of four (4) calendar months ("monitoring period"). This initial monitoring period
can be extended based on mutual consent and written agreement of additional work and price for
such additional work. Anticipated flow monitoring locations are listed in Table 1. Upon approval of
the City, the flow monitoring may be extended by up to two months per the optional costs in the
budget.
a. Data Collection and Equipment Maintenance - ADS will collect data from each monitoring location
remotely using telemetry on a daily schedule (for sites with good wireless signal). The ADS project
team will review the data weekly to ensure each monitor is running properly meeting the project
objectives as well ADS'standards. ADS Field Crews will perform site confirmations, site
maintenance which may include, cleaning the sensor(s), moving, changing or replacing any failed
component ateach monitor location.
3. Demobilization Field crews will continue data collections and confirmations (as necessary) until the
end ofthe monitoring period. Once authorized, crews will immediately begin removing the flow
monitors and deliver final data tuthe data analyst.
C. Phase III Data Editing, Analysis and Reporting
i. Data Analysis Upon completion ofthe monitoring period, atrained ADS Data Analyst will begin to
finalize the data collected for each monitoring location. The data analyst will directly calculate flow
using the continuity equation from recorded depth and average velocity data. Flow quantities as
determined bvthe continuity equation will beplotted.
z. S|i/icerRD|/|Analysis For each of the flow monitoring location, the analysis will characterize the
average dry weather flow conditions and RDI/l calculations for all significant wet weather events, an
assessment ofhydraulic performance under such conditions. The results ofdry weather and wet
weather performance will be plotted on maps of the sewer sheds to make it easier to understand
where RDI/I originates. The Shicer.com section of the Report will include the following items:
� Dry WeatherAnalysis — A characterization of the conditions observed during weekday and
weekend periods of the flow monitoring period during dry weather periods, excluding periods of
extended system recovery to previous rain events. Summarized as a time -series hydrograph of

TASK 400 — FLOW PROJECTIONS
The objective of this task is to develop the sewer flow projections for the sewer service area for the current (2019),
lO-year,and build -out (maximum density) scenarios. Sewer flows will bebased onthe flow monitoring inTask
300 and the City's demographic projections. A new hydraulic model will be created and used to estimate future
wet weather flows. The model will include the developed area south of 1405 and up to two (2) sewer basins north
of4O5. This will not be an all pipe model of the system. The information developed in this task will become
Chapter Flow Projections. This task includes the following activities:
TASK 4OOA(__TiV|T|E,S

4OZ.Update Service Area, Land Use, and Zoning. Basedon[ityp/ovideddata update mapping and
descriptions of existing and future service areas, land use, and zoning for the City Sewer Service Area. The Plan
will include both figures and text.
403. Demographic Projections. Allocate the existing and 10-year and build -out projection of sewered population
and employment provided by the City Planning Department to Sewer Basins. The 10-year growth rates will be
consistent with the Comprehensive Water Plan. The build -out projections are anticipated to be based on
Comprehensive Plan land use.
404. Design Storm. A design storm has been developed from a long term historical rainfall record at a number of
sites near the City. Rainfall data from the ongoing city monitoring program will be reviewed and evaluated to
determine if the design storm previously identified for wet weather flow modeling should be revised. The more
recent data will also be used to evaluate any local rainfall variability and trends. This review will be prepared to
prooidetheCityvvithadefensib|e^Design"sto/mthatemo|ates|oca|vveatherpatterns
405. Develop Existing Dry Weather Flows by Basin. Utilize existing land use maps to develop or confirm average
dry weather flows (ADWF) for the modeled sewer basins. The flows will be confirmed with the flow monitoring
data as well as the available flow data from the lift stations. Existing land use and currently served areas will be
used to estimate flow factors per acre per land use category. The flow factor will be customized to match the
observed existing ADWIF and will be used to develop flow projections. For basins without measured flow data,
flow factors will be assigned from a measured basin with similar land use characteristics.
406.Deve|op 10-year and Build -out Dry Weather Flows by Basin. The City's comprehensive plan and any
additional information on housing densities, commercial and industrial uses will be used along with the flow
factors developed in the above task to determine the ultimate development acreage and the ADWIF for build -out
conditions for uptosewer collection system.
407. Create Hydraulic Model. Using the most recent information from the City's GIS data, create a sewer system
hydraulic model using Innovyze lnfoSWIVIM software. The model will include the developed area south of 1405 and
up to two (2) sewer basins north of 40S. The model will include lift stations and primary collectors, and does not
include the laterals, branches, or smaller truck sewers serving individual parcels within the basins. The City's
existing GIS ArcView ".shp" files will be used to import the collection system data into the hydraulic model. If not
available in the G|S, the City will provide invert elevations at key locations to construct the model. Add |nft station
controls provided by the City to simulate realistic lift station operation. Estimate likely boundary conditions at
connections King County transmission mains, asrequired.
The up to seven (7) basins associated with flow monitoring will be further divided into mini -basins for sanitary and
wet weather loading in the model. These mini -basins will group parcels that contribute to common branches and
trunks, and will beconnected tothe modeled primary collector orlift station atthe appropriate location.
408. Meeting No4 - Hydraulic Model Creation.. Facilitate a meeting with City staff to review and confirm the
elements of the hydraulic model. City staff may be requested to perform field verification of model elements
based on this meeting.
409. Calibrate Existing Dry Weather and Wet Weather Flows. The existing dry and wet weather flows will be
calibrated based upon the flow monitoring data, and rainfall data provided by the City as well as additional data
available from the [ity's S[ADAsystem for optoseven (7) locations inthe collection system. Existing flow depths
and velocities will also bechecked and calibrated.
The first step istocalibrate the model todry weather flow conditions. Flow monitoring data will provide custom
hourly diurnal curves that establish the daily flow patterns for each metering basin. Model results will be
compared to measured flows to check for agreement between model results and measured flows. Model
parameters will be adjusted, as needed, to best match the flow monitoring and SCADA data. It is assumed that
the City will provide SCADA data in electronic format.

Once the dry weather calibration is completed, the wet weather calibration is conducted. Rainfall information will
aid in developing the required rainfall -derived infiltration/inflow (RDI/1) estimations that enter the collection
system during a storm event. Wet weather calibration consists of using three storms that occurred during the flow
monitoring period. It is recommended that the use of a single calibration period incorporating a number of
independent rainfall events should be considered whenever possible. Model results will be reviewed and adjusted,
asneeded, tobest match the flow monitoring, rainfall and SCADAdata.
The flows from unmetered basins will be developed as best possible using a mass balance between the available
data, and proportioned as best as possible based on development type, age, pipe material, and extent of
collection system components.
The hydraulic model will be calibrated in accordance with international modeling standards. The Urban Drainage
Group from the Chartered Institution of Water and Environmental Management (CIWEM) has established
generally agreed upon principles for model verification. The dry weather and wet weather calibration will focus on
meeting the recommendations on model verification contained in the "Code of Practice for the Hydraulic
Modelling of Urban Drainage Systems," published by CIWEM (November 2017).
410. Meeting No. 5 - Model Calibration. Consultant will conduct a workshop (Meeting No. 5) with the City to
summarize the model calibration results. Consultant will present the model calibration results for both dry and
wet weather scenarios, Summary tables will be presented that quantify the percent difference between the
measured data and the modeling results. Consultant will discuss calibration standards and confidence levels at the
workshop.
411. Hydraulic Model Creation and Calibration TM No.2. Consultant will summarize the model creation and
calibration in a Draft and Final TM. Anelectronic version ofdraft TK8will besent tothe City for review and
address City comments in a Final TM that will be included as an Appendix to the Plan.

determine the existing, 10-year, and build out flows peak wet weather flows for the sewer service area. Wet
weather flows will bebased onthe selected design storm.
413. Reclaimed Water. As required by Ecology, reclaimed water opportunities will be updated. The City currently
uses reclaimed water from King County's South Treatment Plant. The City's current use and potential future
customers will be summarized based on information provided by the City. No new analysis is anticipated for this
effort.
413.Draft Chapter 3— Flow Projections. Consultant wi I I summarize the sewer flow projections in Chapter 3: Flow
Projections. It is assumed the efforts in this Task will require a complete update of the Chapter with all new

TASK 300—FLOW MONITORING
This Task will conduct and evaluate flow monitoring to allow accurate estimates of existing and future system
flows so that the City can adequately plan to accommodate its future sewer needs. This task will include flow
monitoring of up to seven (7) locations by a Subconsultant. This task will be documented in TM No.I—Flow
Monitoring that will be included as an Appendix of the Plan. The task includes the following activities:
30I. Review and Update Sewer Service Area and Basins. Review existing sewer service area and basins based on
changes to parcels, collection system piping, and laterals information. It is anticipated the City will provide updated
information electronically. Update Sewer Basins and provide an updated map for City review and confirmation.
302. Identify Primary Collectors and Lift Stations. The City will identify primary collectors and lift stations for
potential flow monitoring and inclusion in the hydraulic model (Task 600). It is anticipated the collectors will be
"skeletonized" to only include pipes greaterthan 12-inch and 8-inch pipes needed to represent flow conditions from
sewer basins. To assist with future tasks, the City will need to provide invert elevations for the selected primary
collectors and information on Lift Stations.
303. Identify Flow Monitoring Locations. Identify recommended locations in install temporary flow monitoring

directed bythe City. Flow monitoring locations will be provided to the City to confirm their suitability for meter
installation.
304 - Flow Monitoring ADS will provide temporary flow monitoring services to Consultant to collect three (3)
months of flow data up to seven (7). After completion of the monitoring, ADS will provide a Rain Dependent
Inflow & Infiltration (RDI/1) Analysis and an electronic report. The work will be performed in three phases as set
forth below:
a. Phase I - Mobilization
�Site Locations ADS will work with the Consultant and the City toidentify/verify the seven (7)
locations for monitor installations. Upon approval by the City, additional locations may be added per
the optional costs inthe budget.
z. Site |nvesticiation_Once the installation sites are provided toADS, ADS field crew($will perform
site investigations. ADS will utilize astandard two (z) person field crew for fieldwork and comply
with Federal standards for confined -space entry. The proposed flow monitoring location will be
located, inspected, and verified for hydraulic suitability. ADS will also check for debris in the
manhole that could impact data quality and coordinate any required cleaning efforts with the City.

ADS field crews will look for evidence and signs oferratic flow patterns. ADS will also investigate
adjacent manholes inorder toidentify the best monitoring locations.
3. Site Reports Site reports will be generated upon completion of the site investigations. The site
reports will include asketch ofthegene/a||ooation,physica|chanacte/ishcsanddiamete/softhe
proposed monitoring locations, manhole depths, flow measurements, and other comments
pertinent tothe location such asany special traffic orsafety issues. Final site locations tobe
approved bvthe Consultant.
4. Equipment ADS will utilize wireless ADS@ Model Triton +T11 flow monitors during the course of this
project. A typical monitor installation will include an ultrasonic depth sensor that will be mounted at
the invert of the pipe, a redundant pressure depth sensor; and a Doppler velocity sensor also
mounted atornear the invert.
S. Monitor Acivati»n Once installed, the monitor will beactivated and set totake readings at5-
minute intervals. ADS Field crews will take manual depth readings with a ruler and velocity readings
with a portable, instantaneous velocity meter in order to confirm the monitor is collecting accurate
data based onthe actual existing hydraulic conditions ateach location.
bPhaseU Flow Monitoring
z. Flow Monitoring Once the monitors are installed and verified to be in working order, ADS will
monitor for a period of four (4) calendar months ("monitoring period"). This initial monitoring period
can be extended based on mutual consent and written agreement of additional work and price for
such additional work. Anticipated flow monitoring locations are listed in Table :L. Upon approval of
the City, the flow monitoring may be extended by up to two months per the optional costs in the
budget.
u. Data Collection and Equipment [Maintenance ADS will collect data from each monitoring location
remotely using telemetry on a daily schedule (for sites with good wireless signal). The ADS project
team will review the data weekly to ensure each monitor is running properly meeting the project
objectives aswell ADS`cLandardc ADS Field Crews will perform site confirmations, site
maintenance which may include, cleaning the sensor(s), moving, changing or replacing any failed
component ateach monitor location.
3. Demobilization Field crews will continue data collections and confirmations (as necessary) until the
end ofthe monitoring period. Once authorized, crews will immediately begin removing the flow
monitors and deliver final data tothe data analyst.
C. Phase III Data Editing, Analysis and Reporting
i. Data Analysis Upon completion of the monitoring period, a trained ADS Data Analyst will begin to
finalize the data collected for each monitoring location. The data analyst will directly calculate flow
using the continuity equation from recorded depth and average velocity data. Flow quantities as
determined bythe continuity equation will beplotted.
z. Sk/icerRD08nay$s For each of the flow monitoring location, the analysis will characterize the
average dry weather flow conditions and RDI/l calculations for all significant wet weather events, an
assessment of hydraulic performance under such conditions. The results of dry weather and wet
weather performance will be plotted on maps of the sewer sheds to make it easier to understand
where RDI/l originates. The Shicer.com section of the Report will include the following items:
� Dty WeatherAnalysis — A characterization of the conditions observed during weekday and
weekend periods of the flow monitoring period during dry weather periods, excluding periods of
extended system recovery toprevious rain events. Summarized asatime-series hydrog/aphof

TASK 400 — FLOW PROJECTIONS
The objective of this task is to develop the sewer flow projections for the sewer service area for the current (2019),
l0-year,and build -out (maximum density) scenarios. Sewer flows will bebased onthe flow monitoring |nTask
300 and the City's demographic projections. A new hydraulic model will be created and used to estimate future
wet weather flows. The model will include the developed area south of 1405 and up to two (2) sewer basins north
of4O5. This will not be an all pipe model of the system. The information developed in this task will become
Chapter Flow Projections. This task includes the following activities:
401. Data Acquisition. Data requests will be provided at the kick-off meeting and as needed throughout the
project. The City will provide:
• Current Nprogram.
r Summary ofNprojects completed since the 20l3Plan.
• Sewer connections bycustomer class.
• Sewer conservation flow reduction rate.
° Map with direct connections toKing County wastewater system.
w Data on number, horsepower, capacity, design point for all pumps at the City's Lift Stations.
• Lift Stations run time.
• City Planning Department existing and future populations and employment based on PSRC's 2040 Vision

and employment provided by the City Planning Department to Sewer Basins. The 10-year growth rates will be
consistent with the Comprehensive Water Plan. The build -out projections are anticipated to be based on
Comprehensive Plan land use.
404. Design Storm. A design storm has been developed from a long term historical rainfall record at a number of
sites near the City. Rainfall data from the ongoing city monitoring program will be reviewed and evaluated to
determine if the design storm previously identified for wet weather flow modeling should be revised. The more
recent data will also be used to evaluate any local rainfall variability and trends. This review will be prepared to
provide the City with a defensible "Design" storm that emulates local weather patterns
405. Develop Existing Dry Weather Flows by Basin. Utilize existing land use maps to develop or confirm average
dry weather flows (ADWF) for the modeled sewer basins. The flows will be confirmed with the flow monitoring
data as well as the available flow data from the lift stations. Existing land use and currently served areas will be
used to estimate flow factors per acre per land use category. The flow factor will be customized to match the
observed existing ADWF and will be used to develop flow projections. For basins without measured flow data,
flow factors will be assigned from a measured basin with similar land use characteristics.
406. Develop 10-year and Build -out Dry Weather Flows by Basin. The City's comprehensive plan and any
additional information on housing densities, commercial and industrial uses will be used along with the flow
factors developed in the above task to determine the ultimate development acreage and the ADWF for build -out
conditions for optosewer collection system.
407. Create Hydraulic Model. Using the most recent information from the City's GIS data, create a sewer system
hydraulic model using Innovyze InfoSWMM software. The model will include the developed area south of 1405 and
up to two (2) sewer basins north of 405. The model will include lift stations and primary collectors, and does not
include the laterals, branches, or smaller truck sewers serving individual parcels within the basins. The City's
existing GIS ArcView ".shp" files will be used to import the collection system data into the hydraulic model. If not
available in the GIS, the City will provide invert elevations at key locations to construct the model. Add lift station
controls provided by the City to simulate realistic lift station operation. Estimate likely boundary conditions at
connections King County transmission mains, asrequired.
The up to seven (7) basins associated with flow monitoring will be further divided into mini -basins for sanitary and
wet weather loading in the model. These mini -basins will group parcels that contribute to common branches and
trunks, and will heconnected tothe modeled primary collector orlift station atthe appropriate location.
408. Meeting No4 - Hydraulic Model Creation.. Facilitate a meeting with City staff to review and confirm the
elements of the hydraulic model. City staff may be requested to perform field verification of model elements
based on this meeting.
409. Calibrate Existing Dry Weather and Wet Weather Flows. The existing dry and wet weather flows will be
calibrated based upon the flow monitoring data, and rainfall data provided by the City as well as additional data
available from the City's SCADA system for up to seven (7) locations in the collection system. Existing flow depths
and velocities will also bechecked and calibrated.
The first step istocalibrate the model todry weather flow conditions. Flow monitoring data will provide custom
hourly diurnal curves that establish the daily flow patterns for each metering basin. Model results will be
compared to measured flows to check for agreement between model results and measured flows. Model
parameters will be adjusted, as needed, to best match the flow monitoring and SCADA data. Itisassumed that
the City will provide SCADA data in electronic format.

aid in developing the required rainfall -derived infiltration/inflow (RDI/1) estimations that enter the collection
system during a storm event. Wet weather calibration consists of using three storms that occurred during the flow
monitoring period. It is recommended that the use of a single calibration period incorporating a number of
independent rainfall events should beconsidered whenever possible. Model results will bereviewed and adjusted,
asneeded, tobest match the flow monitoring, rainfall and S[ADAdata.
The flows from unmetered basins will be developed as best possible using a mass balance between the available
data, and proportioned as best as possible based on development type, age, pipe material, and extent of
collection system components.
The hydraulic model will be calibrated in accordance with international modeling standards. The Urban Drainage
Group from the Chartered Institution of Water and Environmental Management (ClWEM) has established
generally agreed upon principles for model verification. The dry weather and wet weather calibration will focus on
meeting the recommendations on model verification contained in the "Code of Practice for the Hydraulic
K8ode||ingofUrbanDrainageSystems,^pob|ishedbyOVYEK4(November2Ol7).
410. Meeting No. 5 - Model Calibration. Consultant will conduct a workshop (Meeting No. 5) with the City to
summarize the model calibration results. Consultant will present the model calibration results for both dry and
wet weather scenarios. Summary tables will be presented that quantify the percent difference between the
measured data and the modeling results. Consultant will discuss calibration standards and confidence levels at the
workshop.
411. Hydraulic Model Creation and Calibration TM No.2. Consultant will summarize the model creation and
