INDIVIDUAL PROJECT ORDER NUMBER 064512923
Describing a specific agreement between Kimley-Horn and Associates. Inc. (the Consultant). and the City
of Anna (the Client) in accordance with the terms of the fblaster Agreement for Continuing Professional
Services dated July 27"- 2021. which is incorporated herein by reference.
Identification of Project:
Project Name: Wastewater Master Plan Update
KH Project Manager: David Perkins, P.E.
Project Number: 064512923
Specific scope of basic Services:
Project Understanding:
This project consists of updating the existing wastewater master plan completed in 2022
Task 1 — Wastewater Master Plan Update
Kick -Off Meeting:
The Consultant will meet with the City for a formal kick-off meeting for the wastewater master plan. During
this meeting, data collection. the scope for each task. and City contacts will be discussed.
Data Collection:
The Consultant will coordinate .with the City to obtain the following data:
Wastewater Specific Data Collection
Physical Data
■ Lift Stations: total capacity, number of pumps, flow and head range. pump
curves, pump impeller elevation
■ Wastewater treatment plant average day and maximum day capacity
• Wastewater discharge records — Previous five (5) years
Current and historical population (annually)
Current and historical number and type of water connections ("monthly)
Wastewater treatment plant discharge (daily')
Lift station discharge (daily)
Specific commercial industrial meters (daily)
System Operational Parameters and Controls
Lift station pump control settings
• Historical maintenance data
Sanitary Sewer Overflow (SSO) History
Maintenance problem areas
Analvsis:
This task shall consist of compiling existing infrastructure information and demographics to update the
existing hydraulic sewer model for the Client. The model will be updated using industry standard sewer
modeling software such as ' SewerCAD" by Bentley. The model will consist of 10-inch and largerwastewater
lines. Consultant will use this model with the developed design criteria to identify infrastructure
improvements required to alleviate existing deficiencies and to serve future growth. The scope is
anticipated to be as follows:
rev 2021
Existing System Analysis
• Land Use Assumptions — Consultant will incorporate land use assumptions from the current
Comprehensive Plan Update.
• Design Criteria — Consultant will develop design criteria that meets Texas Commission on
Environmental Quality (TCEQ) regulations and industry design standards for:
Sewer line capacity
Lift station and force main capacity
• Existing Wastewater Demands — Consultant will utilize the City's existing wastewater discharge
data and field data to calculate the Clients existing and historical wastewater discharges. Tasks
will include:
Calculate historical and current average day, dry weather wastewater discharges for
the City and for the 10 wastewater basins.
Calculate historical and current average day, dry weather wastewater discharges by
each unique land use type.
Calculate a representative diurnal wastewater demand curve for the City and for each
wastewater basin.
_ Calculate wet weather wastewater discharges for the City and for each wastewater
basin for each unique rainfall event.
• Wastewater System Model — Consultant will update the City's wastewater system model to
represent the existing wastewater system and existing wastewater system demands. The
model will utilize existing infrastructure information, system operational parameters, and
available customer demand information. Tasks will include:
Evaluate system connectivity.
Confirm pipe and node parameters, such as pipe size, roughness factor, and node
elevation.
Confirm system components, such as lift stations, are shown in the model with the
correct location, connectivity, and geometry.
Confirm system operational parameters and controls.
_ Evaluate the distribution of existing demands.
• Model and Infrastructure Verification
Consultant will calibrate the model using flow monitoring data provided by the Client.
Consultant will coordinate with Client staff to verify that the existing infrastructure
matches the wastewater system model.
Perform a calibration analysis to compare model results with the recorded data.
Capital Improvement Plan
Wastewater System Analysis and Infrastructure Sizing — Consultant will utilize the wastewater
system model to determine existing infrastructure that does not meet the design criteria and to
size infrastructure to serve future growth. Tasks will include:
Determine sewer shed boundaries for the service area and establish a 1071' major
wastewater basin.
Identify infrastructure needed to alleviate existing system deficiencies.
Utilize future land use projections to prepare projected demand distributions and
incorporate into the model.
Execute the model to identify infrastructure improvements necessary to meet future
demands.
Develop flow rate or connection number triggers for each major wastewater projects
with a projected improvement year.
The following components will be evaluated and sized:
■ Transmission Lines
• Lift Stations
• Treatment Facilities
Capital Improvement Plan — Consultant will develop a wastewater Capital Improvement Plan
rev 1 02'.
that identifies projects to be constructed. Tasks will Include:
Develop capital improvements project list.
_ Develop opinions of probable construction cost for each project.
CIP Meeting
The Consultant will meet with the City to discuss the proposed CIP and preliminary cost projections. Any
comments will be incorporated into the final CIP and cost projections.
Report:
Consultant will update the Wastewater Master Plan report summarizing the findings of the analysis and the
recommendations.
• Prepare draft report for review and comment by Client.
• Prepare final report based on Client comments.
• The report is anticipated to include the following:
Executive summary
Introduction
Description of existing infrastructure
Design criteria and modeling methodology
Existing wastewater system deficiencies
_ Future land use and wastewater demand projections
Analysis and recommendations
Capital improvements plan
■ Opinion of probable construction cost
• Project description
Maps
