these areas. Initially, this information will be combined with the allowable
population density based on zoning and the projected uses to establish
future and ultimate demands.
3.2.1.3 Redevelopment Review - Review the potential for redevelopment with City
Staff and city planning documents. Develop an understanding of the
potential redevelopment impacts to the City water demands.
3.2.1.4 Estimate Future Demands - Combine current updated demand data
(acquired from billing data), with demand projections for undeveloped and
redevelopment areas to determine a best estimate of projected demand for
intermediate demand scenarios between existing and build -out conditions.
The following scenarios will be evaluated:
3.2.1.4.1 Present (baseline) (2017 — including near-term/CIP
improvements)
3.2.1.4.2 Intermediate 10 year (2027) planning period
3.2.1.4.3 Intermediate 10 year (2027) planning period including
regionalization
3.2.1.4.4 Ultimate Buildout (2035)
3.2.1.4.5 Ultimate Buildout (2035) including regionalization
These projected demands will be prepared as average annual demand
throughout the City. Demands will be applied to vacant parcels and parcels
identified as viable redevelopment candidates based on the land use.
Demand scenarios will include a reasonable/conservative estimate for use in
future planning for new developments. A table will be prepared using current
demand as a baseline for comparison. Demand values will be distributed as a
single demand split to one or more model junctions as described in Task

3.2.3.3 Provide historical billing data
3.2.3.4 Provide operation data for pressures, flows, and tank levels
3.2.3.5 Provide annual WTP production
3.3. Model Improvement
The model improvement task includes a comprehensive review of the existing model
configuration and operation with modifications provided to reflect changes that have taken
place in the system or in the system operations since the last master plan. Changes in the
system will be presented for visual review. New data sources will also be incorporated into the
revised system.
The updated model will be capable of evaluating changes in projected water demands,
pressure criteria, and fire flows, and the impacts of improvements to the distribution system.
Operational improvements will be made to the model based on new data on operation and on
improved model demand distribution, diurnal pattern assignments, physical layout, C -factors,
and major facility operations.
3.3.1. Following are the individual activities that are included in this task:
3.3.1.1 Update Svstem/GIS —The first component of this project involves
upgrading the hydraulic model to better represent current system
conditions. The pipe configuration in the model will be verified through
direct comparison to the GIS and the model will be updated to reflect the
current state of the distribution system, as detailed in the GIS. This will
likely be performed as complete rebuild using current GIS data, merged
with the key hydraulic features in the existing model (pumps, tanks, etc.)
that are not reflected in the GIS. This also includes conversion from the
existing hydraulic model format from H2O Net to Bentley Water Gems in
accordance with City requirements for future "real-time" water system
monitoring capability.
3.3.1.2 Distribute Demands - A key component of the demand development
process involves improvements to the current demand allocation in the
City's model. The budget developed for this task approach assumes that

the demands from each parcel will be proportionally split, using model
tools, to the existing model nodes on either end of the main linking these
nodes. This proportional split will be made using geocoded customer
billing points.
Current water demands will be used for establishing the baseline model.
There are three components of a complete demand allocation that will be
further developed using available data:
3.3.1.2.1 Average Demands - The annual average demand for every
customer will be linked to each parcel. This volume will be
developed by taking a year of data from the billing system and
assigning it directly to the meter location or parcel via
geocoding or another viable method. The demand values will be
assigned as described above using tools provided in the
modeling software suite.
3.3.1.2.2 Peaking Factors —Use the available operation data and
production data to identify the peak and minimum demand
periods and associated factors. These factors will be applied
universally to all demands to develop maximum and minimum
day scenarios. These different demand conditions will be
simulated using the scenario management capabilities of the
model and by changing the base operating parameters for
different alternatives that will then be associated with the
appropriate scenarios. Scenarios will be created for average
day, minimum day, maximum day, and peak hour demand
conditions. All of these scenarios will typically be operated in
extended period mode. The peak hour demand condition will be
simulated as the highest hour on maximum day, unless the peak
hour demand is consistently shown to not occur on maximum
day. In this case, the project team and the City will decide on
the best course of action to simulate this condition. These
scenarios will be created as children of the "Base" model that
will simulate actual, best known current conditions.
3.3.1.2.3 Unaccounted -for -water (UFW) — Billing data for an extended
period will be compared to operation data to estimate the
unaccounted -for -water volume (UFW) will be distributed across
the system based on discussions with City staff. Traditionally,
UFW demand is simply divided by the number of model nodes
and distributed evenly to each node. Performance of this task is
necessary for the successful documentation of water loss for

the TWDB as well as implementing corrective action measures
through the implementation of the Advanced Metering
Infrastructure (AMI) program in increase water accountability
which is required by TWDB as a condition of the funding
mechanism.
3.3.1.3 Review Diurnal Patterns - Review the diurnal demand patterns for each
customer type and update them, if necessary.
3.3.1.4 Verify Facility Operations - Assess the capabilities and limitations of the
existing hydraulic model, and identify required system improvements.
Pump operations will be reviewed so they reflect current operations at
each pumping location. Control valve operation and settings will be
verified with operational staff so that these devices are modeled as they
are operated. If operational settings change seasonally, these changes will
be noted and appropriate scenarios created to model the range of
conditions so that maximum day and minimum day demand scenarios are
appropriately handled from a control standpoint. Units will be modified as
needed for pumps, controls, etc.
3.3.1.5 Scenario Manaeement - Recommendations for how the scenario
management capabilities of the model will be used to support a wide
range of modeling activities will be developed. This will include
recommendations for applying both the scenario management tools and
facility sets to achieve the intended operations for different model runs.
The recommended and agreed upon scenario tree within the delivered
model will be created. The different modeled scenarios will include
descriptions on the conditions that each scenario represents.
3.3.1.6 As shown in the future demand development section above, the following
scenarios will be evaluated:
3.3.1.6.1 Present (baseline) (2017 — including near-term/CIP
improvements)
3.3.1.6.2 Intermediate 10 year (2027) planning period
3.3.1.6.3 Intermediate 10 year (2027) planning period including

Detailed Scope of Services
The system demand alternatives will also include the following subsets
that will be represented by the use of either global factors or different
diurnal patterns:
■ Average Day
■ Maximum Day
• Peak Hour (may be simulated as part of maximum day if
appropriate)
■ Minimum Day
The model will be operated in the following different analysis modes:
• Extended Period Simulations — Review of tank and reservoir use
and capability to maintain desired pressures and other "level -of -
service" indicators during the course of expected operations, such
as water age. All "normal" runs — average day, maximum day,
minimum day — for all scenarios will be made in extended period
mode.
• Steady State — Adequacy of pumping and conveyance for
maintaining system pressure based on TCEQ standards, including
35 psi for average conditions, with a 20 psi minimum at point of
delivery. High pressure will also be evaluated.
The distribution system components will vary from run to run consistent
with the modeled time frame. This will be performed using facility sets
instead of, for example, using open/closed status of pipes to change the
modeled features from one scenario to another. Facility sets will be based
on database queries rolled up into a single query set for each time frame.
Model time frames consistent with the different future demand scenarios
will be created as follows:
■ Base conditions (existing features only)
• CIP facilities (existing, less features to be removed, plus features
to be added at specified times in the CIP, for up to three modeled
future scenarios)
• Ultimate (existing facilities plus all CIP projects, less existing
facilities to be removed)

land use will be developed with the City.
3.2.1. The following detailed activities are the scope of services for this task:
3.2.1.1 Review and Update Proiections — This activity includes a brief review of the
data, assumptions, process and results of the water demand projections
from the prior master plans. A meeting will be scheduled with the City to
verify existing demands and discuss their plans for future water demands.
3.2.1.2 Development Review — Open, developable land in the service area will be
evaluated for development use and a demand estimate will be prepared for
these areas. Initially, this information will be combined with the allowable

population density based on zoning and the projected uses to establish
future and ultimate demands.
3.2.1.3 Redevelopment Review - Review the potential for redevelopment with City
Staff and city planning documents. Develop an understanding of the
potential redevelopment impacts to the City water demands.
3.2.1.4 Estimate Future Demands - Combine current updated demand data
(acquired from billing data), with demand projections for undeveloped and
redevelopment areas to determine a best estimate of projected demand for
intermediate demand scenarios between existing and build -out conditions.
The following scenarios will be evaluated:
3.2.1.4.1 Present (baseline) (2017 — including near-term/CIP
improvements)
3.2.1.4.2 Intermediate 10 year (2027) planning period
3.2.1.4.3 Intermediate 10 year (2027) planning period including
regionalization
3.2.1.4.4 Ultimate Buildout (2035)
3.2.1.4.5 Ultimate Buildout (2035) including regionalization
These projected demands will be prepared as average annual demand
throughout the City. Demands will be applied to vacant parcels and parcels
identified as viable redevelopment candidates based on the land use.
Demand scenarios will include a reasonable/conservative estimate for use in
future planning for new developments. A table will be prepared using current
demand as a baseline for comparison. Demand values will be distributed as a
single demand split to one or more model junctions as described in Task
3.4.1.2.

City Staff Involvement
• Interactive meetings regarding model inputs and operation
• Planning meeting to determine expected development and determine demand
projections
• Provide historical billing data
• Provide operation data for pressures, flows, and tank levels
• Provide annual WTP production
3.3. Model Improvement
The model improvement task includes a comprehensive review of the existing model
configuration and operation with modifications provided to reflect changes that have taken
place in the system or in the system operations since the last master plan. Changes in the
system will be presented for visual review. New data sources will also be incorporated into the
revised system.
The updated model will be capable of evaluating changes in projected water demands,
pressure criteria, and fire flows, and the impacts of improvements to the distribution system.
Operational improvements will be made to the model based on new data on operation and on
improved model demand distribution, diurnal pattern assignments, physical layout, C -factors,
and major facility operations.
3.3.1. Following are the individual activities that are included in this task:
3.3.1.1 Update Svstem/GIS —The first component of this project involves
upgrading the hydraulic model to better represent current system
conditions. The pipe configuration in the model will be verified through
direct comparison to the GIS and the model will be updated to reflect the
current state of the distribution system, as detailed in the GIS. This will
likely be performed as complete rebuild using current GIS data, merged
with the key hydraulic features in the existing model (pumps, tanks, etc.)
that are not reflected in the GIS. This also includes conversion from the
existing hydraulic model format from H2O Net to Bentley Water Gems in
accordance with City requirements for future "real-time" water system
monitoring capability.
3.3.1.2 Distribute Demands - A key component of the demand development
process involves improvements to the current demand allocation in the
City's model. The budget developed for this task approach assumes that
[1P
KIT Professionals, Inc.
Page 5
Task Order No. 3
KIT's Scope of Services
[1,
KIT Professionals. Inc.
the demands from each parcel will be proportionally split, using model
tools, to the existing model nodes on either end of the main linking these
nodes. This proportional split will be made using geocoded customer
billing points.
Current water demands will be used for establishing the baseline model.
There are three components of a complete demand allocation that will be
further developed using available data:
3.3.1.2.1 Averaee Demands - The annual average demand for every
customer will be linked to each parcel. This volume will be
developed by taking a year of data from the billing system and
assigning it directly to the meter location or parcel via
geocoding or another viable method. The demand values will be
assigned as described above using tools provided in the
modeling software suite.
3.3.1.2.2 Peaking Factors —Use the available operation data and
production data to identify the peak and minimum demand
periods and associated factors. These factors will be applied
universally to all demands to develop maximum and minimum
day scenarios. These different demand conditions will be
simulated using the scenario management capabilities of the
model and by changing the base operating parameters for
different alternatives that will then be associated with the
appropriate scenarios. Scenarios will be created for average
day, minimum day, maximum day, and peak hour demand
conditions. All of these scenarios will typically be operated in
extended period mode. The peak hour demand condition will be
simulated as the highest hour on maximum day, unless the peak
hour demand is consistently shown to not occur on maximum
day. In this case, the project team and the City will decide on
the best course of action to simulate this condition. These
scenarios will be created as children of the "Base" model that
will simulate actual, best known current conditions.
3.3.1.2.3 Unaccounted -for -water (UFW)— Billing data for an extended
period will be compared to operation data to estimate the
unaccounted -for -water volume (UFW) will be distributed across
the system based on discussions with City staff. Traditionally,
UFW demand is simply divided by the number of model nodes
and distributed evenly to each node. Performance of this task is
necessary for the successful documentation of water loss for

the TWDB as well as implementing corrective action measures
through the implementation of the Advanced Metering
Infrastructure (AMI) program in increase water accountability
which is required by TWDB as a condition of the funding
mechanism.
3.3.1.3 Review Diurnal Patterns - Review the diurnal demand patterns for each
customer type and update them, if necessary.
3.3.1.4 Verify Facility Operations - Assess the capabilities and limitations of the
existing hydraulic model, and identify required system improvements.
Pump operations will be reviewed so they reflect current operations at
each pumping location. Control valve operation and settings will be
verified with operational staff so that these devices are modeled as they
are operated. If operational settings change seasonally, these changes will
be noted and appropriate scenarios created to model the range of
conditions so that maximum day and minimum day demand scenarios are
appropriately handled from a control standpoint. Units will be modified as
needed for pumps, controls, etc.
3.3.1.5 Scenario Manasement - Recommendations for how the scenario
management capabilities of the model will be used to support a wide
range of modeling activities will be developed. This will include
recommendations for applying both the scenario management tools and
facility sets to achieve the intended operations for different model runs.
The recommended and agreed upon scenario tree within the delivered
model will be created. The different modeled scenarios will include
descriptions on the conditions that each scenario represents.
As shown in the future demand development section above, the following scenarios
will be evaluated:
• Present (baseline) (2017 — including near-term/CIP improvements)
• Intermediate 10 year (2027) planning period
• Intermediate 10 year (2027) planning period including regionalization
• Ultimate Buildout (2035)
• Ultimate Buildout (2035) including regionalization
The system demand alternatives will also include the following subsets that will be
represented by the use of either global factors or different diurnal patterns:
Page 7
Task Order No. 3
KIT's Scope of Services
• Average Day
• Maximum Day
• Peak Hour (may be simulated as part of maximum day if
appropriate)
• Minimum Day
The model will be operated in the following different analysis modes:
• Extended Period Simulations — Review of tank and reservoir use
and capability to maintain desired pressures and other "level -of -
service" indicators during the course of expected operations, such
as water age. All "normal" runs — average day, maximum day,
minimum day — for all scenarios will be made in extended period
mode.
• Steady State — Adequacy of pumping and conveyance for
maintaining system pressure based on TCEQ standards, including
35 psi for average conditions, with a 20 psi minimum at point of
delivery. High pressure will also be evaluated.
The distribution system components will vary from run to run consistent with the
modeled time frame. This will be performed using facility sets instead of, for
example, using open/closed status of pipes to change the modeled features from
one scenario to another. Facility sets will be based on database queries rolled up
into a single query set for each time frame. Model time frames consistent with the
different future demand scenarios will be created as follows:
• Base conditions (existing features only)
• CIP facilities (existing, less features to be removed, plus features
to be added at specified times in the CIP, for up to three modeled
future scenarios)
• Ultimate (existing facilities plus all CIP projects, Tess existing
facilities to be removed)
• Operation Recommendation scenarios
Overall Modeling objectives include:

3.4. Model Verification
Backeround on Aooroach
After review of the model configuration has been completed and modifications to model
inputs have been performed and confirmed by the City, the hydraulic model will be verified.
The verification process depends on data collected from the distribution system that reflects
