This Agreement is made and entered by and between AECOM Technical Services, Inc., 501
Sycamore Street, Suite 222, Waterloo, Iowa, hereinafter referred to as "ATS" and City of Waterloo,
715 Mulberry Street, Waterloo, Iowa, hereinafter referred to as "CLIENT."
IN CONSIDERATION of the covenants hereinafter set forth, the parties hereto mutually agree as
follows:
I. SCOPE OF SERVICES
ATS shall perform professional Services (the "Services") in connection with CLIENT's facilities
in accordance with the Scope of Services set forth in Exhibit A attached hereto.
II. ATS'S RESPONSIBILITIES
ATS shall, subject to the terms and provisions of this Agreement:
(a) Appoint one or more individuals who shall be authorized to act on behalf of ATS and
with whom CLIENT may consult at all reasonable times, and whose instructions,
requests, and decisions will be binding upon ATS as to all matters pertaining to this

(b) Use all reasonable efforts to complete the Services within the time period mutually
agreed upon, except for reasons beyond its control.
(c) Perform the Services in accordance with generally accepted professional engineering
standards in existence at the time of performance of the Services. If during the two
year period following the completion of Services, it is shown that there is an error in
the Services solely as a result of ATS's failure to meet these standards, ATS shall re-
perform such substandard Services as may be necessary to remedy such error at no
cost to CLIENT. Since ATS has no control over local conditions, the cost of labor and
materials, or over competitive bidding and market conditions, ATS does not
guarantee the accuracy of any construction cost estimates as compared to
contractor's bids or the actual cost to the CLIENT. ATS makes no other warranties
either express or implied and the parties' rights, liabilities, responsibilities and
remedies with respect to the quality of Services, including claims alleging negligence,
breach of warranty and breach of contract, shall be exclusively those set forth herein.
(d) ATS shall, if requested in writing by CLIENT, for the protection of CLIENT, require
from all vendors and subcontractors from which ATS procures equipment, materials
or services for the project, guarantees with respect to such equipment, materials and
services. All such guarantees shall be made available to CLIENT to the full extent of
the terms thereof. ATS's liability with respect to such equipment, and materials
obtained from vendors or services from subcontractors, shall be limited to procuring
guarantees from such vendors or subcontractors and rendering all reasonable
assistance to CLIENT for the purpose of enforcing the same.

WATERLOO SANITARY SEWER ANALYSIS - HYDRAULIC MODELING
CITY OF WATERLOO, IOWA
EXHIBIT A
A. PROJECT DESCRIPTION
The project consists of conducting computer modeling of the sanitary sewer system in the
City of Waterloo, Iowa. The model will be developed using XP-SWMM and include sanitary
sewers of 8 inches and larger in diameter, and the City's lift stations will be incorporated
into the model. Flow monitoring efforts conducted under a parallel effort will serve the dual
purpose of evaluating the system response to inflow and infiltration (1/1) as well as for
calibration of the sanitary sewer model. The model will be calibrated for dry and wet
weather flows, based on the collected flow meter information, and validated with known
anecdotal flooding and bypass information.
B. SCOPE OF SERVICES
The Scope of Services will encompass and include all detailed work, services, materials,
equipment, personnel and supplies necessary to provide regulatory requirement review,
collection and review of existing information, database review, GIS/model development,
hydraulic modeling, and project administration and meetings. The Scope of Services is
further defined as follows:
Project Development Plan and Regulatory Review
Task 1 - Develop Draft Project Plan. This document will describe the project goals and how
these goals will be achieved. It will describe the scope of services, schedule, milestones
and deliverables.
Task 2 - Attend project kickoff meeting.
Task 3 - Revise project plan based on comments from the kickoff meeting.
Task 4 - Regulatory Requirement Review. Review and summarize existing, pending, and
future regulatory requirements and project goals for future phases, including EPA directives
for this project.
Collection and Review of Existing Information
Task 5 - Review previous studies and modeling efforts.
Task 6 - Collect geographic information system (GIS), CADD and other digital data on the
existing sanitary sewer network (pipes and manholes), external database for inverts,
sanitary sewer service areas and catchments.
Task 7 - Collect information on customers, including but not limited to, connection points,
catchment areas, land use data, census data, and identified high water users. (It is
assumed, at a minimum, that land use and census data will be available in a digital format
that can be utilized by the project team.)
Task 8 - Collect pumping station information, including number of pumps, type, rated
capacity, pump curves, operational controls and pump run time/flow data. Assumes up to
20 pump stations will be evaluated within the model in detail. The other 6 pumps will be
modeled either as a point flow or smaller catchment that does not include pump details.
Task 9 - Collect anecdotal flooding and bypass information, including known basement
backup locations, bypass volumes and WWTP data.
Interceptor Database
Task 10 - Meet with WWTP Staff to discuss data sources and approach for developing the
project GIS components needed for modeling.
Task 11 - Review sanitary sewer system geodatabase for data gaps and errors using
queries. Use GIS and/or modeling tools to check and document data gaps and errors.
Task 12 - Make recommendations for the sanitary sewer system geodatabase
modifications/approach for model development.
GIS/Model Development
Task 13 - Develop digital relationship between the City GIS sanitary sewer inventory data
and the 1986 sanitary sewer system and data for roughly 9,000 data points (manholes).
Compare current GIS mapping to sanitary sewer map tiles that contain a manhole name
that matches a spreadsheet based on the 1986 Facilities Plan. Manually correlate the two
naming conventions by incorporating into a spreadsheet or database to develop a common
attribute name relative to the other naming convention.
Task 14 - Review CADD, GIS, as -built and other data sources to identify new and replaced
pipe network components since the 1986 study was completed. Develop database and
map/network information to incorporate into GIS/model.
Task 15 - Build network (pipes and manholes) with GIS. Starting with the City's GIS
system, incorporate the pipe information from the 1986 study by utilizing the common
attribute link developed in Task 13. Populate pipe diameter, material and invert information.
Incorporate new/replaced pipe network information developed under Task 14.
Hydraulic Modeling
Task 16 - Model Development:
a. Build network (pipes and manholes) with GIS utilizing comprehensive, City -
developed digital sanitary sewer system data.
b. Import sewer service areas and delineate catchments at flow meter
locations and pump stations.
c. Further delineate subcatchments in areas to develop flows within the
model, in some cases down to approximately one City block in size.
d. Intersect population coverage (census block or parcels) with
subcatchments. Estimate population per subcatchment.
e. Add subcatchments and population to model.
f. Add unit area and per capita flow parameters to model.
g. Add pumping stations and pump curves to model.
h. Add other appurtenances to the model.
i. Run and debug model.
Task 17 - Dry Weather Calibration:
a. Develop diurnal pattern for each of the 25 flow meters.
b. Add diurnal patterns to the model for weekdays and weekends.
c. Calibrate model for each meter location by adjusting per capita flow rates.
Add base flow where necessary.
Task 18 - Wet Weather Calibration:
a. Select a metered wet weather event for modeling, presumably the largest
event during the metering period.
b. Evaluate rainfall and rain gauge data and develop one or more rainfall
patterns for input into the model.
c. Review flow apportionment based on available flow data and level of
service flows.
d. Import flow data into the model for heavy water users or other sources not
explicitly modeled.
e. Calibrate isolated basins based on flow meter data.
f. Calibrate downstream meters requiring meter (flow) subtraction.
g. Calibrate pump stations based on collected data (assumes up to 20
locations).
h. Calibrate for up to 10 locations for bypassing/SSOs, assuming a significant
event occurs during monitoring.
i. Calibrate model hydraulics by adjusting hydraulic parameters, where
necessary, to account for sediment, downstream flow restrictions and other
significant losses.
j. Validate the model to another wet weather flow event. Adjust calibration
parameters, where necessary, to match validation event and calibration
event.
k. Validate the model to an event known to produce flooding and/or
bypassing. Rainfall data from the WWTP and other sources (e.g.,
WeatherUnderground.com) will be used.
I. Provide maps and develop technical memorandum documenting model
development, existing deficiencies, identification of future model needs and
application.
