Background
The original Task Order(TO)provides engineering services for Carollo Engineers, Inc.(Carollo)to update and
calibrate the City's wastewater model and the City's potable water model to existing infrastructure and
operating conditions.This amendment adds new tasks to use the calibrated models to evaluate immediate
system needs.Carollo understands that the City is also interested in the identification and timing of future
needs(a Master Plan),however,that stage will be covered under a separate assignment.
The scope changes and proposed additions are as follows:
TASK 1 PROJECT MANAGEMENT AND MEETINGS
Amendment to Subtask 1.2—Project Management and Communication
Time to perform project management activities for an additional duration(four months),along with
corresponding communication.
Amendment to Subtask 1.2—Project Kickoff Meeting and Progress Meetings
Two(2)additional progress meetings(in person),one for each system,will be added for the coordination
and presentation of additional tasks.
(No amendment to Subtask 73)
TASK 2—DATA COLLECTION AND ANALYSIS
Amendment to Subtask 2.4—GIS Data&Coordination
Using successive versions of the City's GIS database,Carollo will update both the potable water distribution
and wastewater collection system models to address data gaps and inconsistencies identified in the initial
datasets,with particular focus on pipe diameters and material attributes.
Model elements within both the potable water and wastewater models will also be renamed and reindexed
to align with the Asset IDs provided in the City's GIS shapefiles,improving consistency between the models
and the City's asset management records.
New Subtask 2.8—Flow Meter Package and Installation
Carollo will coordinate the procurement and installation of a clamp-on flow meter and associated
transducers on a wastewater force main near the intersection of N.Congress Avenue and Savannah Lakes
Drive,as requested by the City.
The cost of the flow meter and related vendor services are as follows:
1. The proposed equipment to be procured on behalf of the City includes the following:One unit of
Flexim F401 flow meter(tem 410011-20)
2. Two sets of flow transducers(items 411020-2 and 411021-2)
3. One unit of Flexim Power Pack PP026NN backup battery(item 412060-6)
First Amendment to Task Order No. GESUT-3C-03-25 —Carollo Engineers, Inc. Page 6 of!!
The selected vendor will deliver the equipment to the project site and provide installation,start-up,and
operational support services,including on-site training for City staff on equipment installation.operation,
data interpretation,and use of the associated data visuali_ation software(Fluxdiag).
Following installation,Carollo will conduct site visits,as needed,to download,review,and process flow
monitoring data collected upstream of Master Lift Station 317.
(No Change to Subtasks 2.1,22,2 3,and 25 through 2 7)
TASK 3-HYDRAULIC MODELS CONVERSION AND UPDATE
Amendment to Subtask 3.1—Gravity Main and Force Main Extensions In Wastewater Model
Under the original Task Order(TO),Task 3.1 did not include updates to portions of the collection system
upstream of gravity mains due to the absence of recorded invert elevations at manholes,which are required
for gravity system modeling.
• To address this limitation,Carollo identified lift stations and force mains that could be incorporated
into the wastewater model and calibration effort if invert elevation data for selected upstream
gravity segments were made available.Based on this assessment,the City proposed to provide the
necessary records and amend the scope to include the following additional system components:3.6
miles of gravity segments,with its manholes,
• 27 additional lift stations (for a total of 131 simulated lift stations),
• 27.9 additional miles of force main that are connected upstream of the identified gravity segments
(for a total of 75.3 miles),
With the inclusion of these data,Carollo will update the wastewater hydraulic model to incorporate the
identified gravity pipe segments and manholes,the additional upstream lift stations,and the associated
interconnecting force mains,and will integrate these elements into the overall model calibration effort.
Amendment to Subtask 3.3—Addition of New Lift Stations Operational Attributes
Pump curves,pump control(on/off)levels,logic controls/operational rules consistent with information
provided will be included in the wastewater model.
(No amendment to Subtasks 32,3.4,3.5,and 3.6)
TASK 4--HYDRAULIC MODELS CALIBRATION AND EXISTING SCENARIOS
Amendment to Subtask 4.1—Calibrating with Additional Infrastructure in the Dry Weather
Calibration
In addition to the effort to physically include infrastructure in the model,calibration of the model with this
new infrastructure operating in current dry weather conditions is also required.Carollo will adjust appropriate
variables such as flow allocations and diurnal patterns, lift station operation settings, roughness coefficients in
this infrastructure,as in the originally anticipated infrastructure,to calibrate the model.
First Amendment to Task Order No. GESUT-3C-03-25 —Carollo Engineers, Inc. Page 7 of 11
Amendment to Subtask 4.2-Calibrating with Additional Infrastructure in the Wet Weather
Calibration
Carollo will adjust inflow and infiltration potential in this infrastructure and its upstream sewersheds,as in the
originally anticipated infrastructure,to calibrate the model to wet weather conditions.
(No amendment to Subtask 43)
TASK 5—DELIVERABLES AND DOCUMENTATION -Amendment
The work performed under this amendment will generate additional model results and supporting
documentation that build upon and complement the deliverables established under the original scope of
services.These results will support a more forward-looking planning framework and provide an enhanced
technical basis for future master planning efforts.
Two summary sections will be added to the Draft and Final Technical Memorandums:
• Water and Wastewater System Assessments Summary
• Business Case Scenarios Summaries
The hydraulic models deliverables(in sewerGEMS and WaterGEMS format)will include one additional
scenario per business case evaluated.Refer to New Task 6 and New Task 7 for a list of scenarios.
NEW TASK 6—WATER AND WASTEWATER SYSTEM ASSESSMENTS
The objective of completing the performance assessments is to identify hydraulic deficiencies with respect to
City's standard level of service,standard service standards,and industry performance criteria,to define and
prioritize capital investment needs.Because the models utilized for these analyses will not yet include future
scenarios(which are typically developed in Master Plans),the identified needs will all be considered
"immediate".Priority will be assessed by evaluating 1)how sustained in a 24-hour simulation a deficiency with
respect to the criterion is,and 2)the approximate number of customers(accounts)affected.When
deficiencies may be solved using operational optimization strategies,such strategies will be tested in the
model and suggested to the City when found feasible.These assessments are intended to provide a reliable
technical basis for identifying/understanding and addressing issues and to respond to regulatory agency
inquiries with confidence.Aside from being useful to assess the system needs,these scenarios will be useful
in the future to evaluate potential infrastructure and project proposals.
As part of this effort system deficiencies,capacity limitations,and risks associated with the duration and
location of the deficiencies,will be evaluated across dry-weather and wet-weather conditions for the
wastewater system,and across average,maximum,and peak demands for the potable water system.
New Subtask 6.1—Wastewater Collection System Assessment
The following assessments will be completed using the calibrated wastewater hydraulic model:
• Identify lift station capacity exceedances under dry and wet weather scenario and determine
associated pump replacement or upgrade needs.
• Evaluate force main capacity under both dry-weather and wet-weather conditions.
First Amendment to Task Order No. GESUT-3C-03-25 —Carollo Engineers, Inc. Page 8 of 11
Capital improvement projects will be proposed to resolve identified performance and capacity constraints.If
options to improve the identified deficiencies by changing operations are identified,the model will be used
to test such options and a list of selected suggestions provided.
New Subtask 6.2—Water Distribution System Assessment
The following will be completed using the calibrated water hydraulic model:
• Assessment of the existing distribution and transmission pipelines relative to typical municipal
design standards,including velocity and pressure criteria,to assess system performance and
identify potential capacity or operational constraints.
• Identification of restrictions and headloss within the existing distribution system,including
constraints at canal crossings.
Capital improvement projects will be proposed to resolve identified performance and capacity constraints.If
options to improve the identified deficiencies by changing operations are identified,the model will be used
to test such options and a list of selected suggestions provided.
NEW TASK 7—BUSINESS CASE SCENARIOS
The main goal of these scenarios and their analyses is to generate operational and management strategies
that work hydraulically and promote economic sustainability for the City.The additional scenarios can also be
used to respond to regulatory agency inquiries with certainty and to test alternative business-case
assumptions.Under this amendment,only business case scenarios that evaluate existing infrastructure will be
evaluated.Future scenarios(which require flow and demand projections and their allocation)are not
induded and will be developed and assessed to identify future needs for capital improvement under a
different work assignment.
New Subtask 7.1—Wastewater Collection System Business Case Scenarios
Assignments proposed include:
• Assess the impacts of inflow and infiltration(I/I)on pumping and force main capacity.
• Evaluate lift station pumping efficiency based on pump starts per hour,wet well retention times,
and pump on/off control logic under severe wet weather flow conditions.
• Assess the ability of the collection system to convey flows to the SCRWWTP using diversion and
isolation valves under emergency operating conditions.
• Evaluate the impacts associated with changes in large customer demands and a septic-to-sewer
conversion scenario.
Findings for each of the above scenarios will be listed and potential solutions, both from an operational and
capital improvement standpoint,will be provided.
Subtask 7.2—Potable Water Distribution Business Case Scenarios
Scenarios will be developed with the aim of completing the following:
First Amendment to Task Order No. GESUT-3C-03-25 —Carollo Engineers, Inc. Page 9 of 11
• Evaluate water quality based on water age for the existing system and under conditions where
the system is served by a single treatment facility(3 scenarios).
• Evaluate the ability to serve the City using a single water treatment plant(WTP), including
impacts on interconnections with neighboring utilities.
• Assess fire flow availability throughout the distribution system.
• Evaluate the impacts associated with systemwide increases or decreases in water demand.
Findings for each of the above scenarios will be listed and potential solutions,both from an operational and
capital improvement standpoint,will be provided.
PROJECT SCHEDULE
The original contract schedule,which was preliminarily adjusted in July 2025,anticipated project completion
by the end of March 2026.
Several tasks included in this amendment have already been completed,including flow meter procurement,
additional GIS data processing and usage, and the gravity main,force main,and lift station extensions in the
wastewater model.For the remaining scope of work,it is anticipated that new tasks will require
approximately three additional months to complete following the work under the original PO,as in Table 2.
