INTRODUCTION
This memorandum requests the City Council set a public hearing on May 20, 2024, for
the Granger Creek Lift Station Improvements Project.
BACKGROUND
In 1998 the City began to extend sanitary sewer along Granger Creek, for the Dubuque
Technology Park development. The Granger Creek Interceptor Sewer (GCIS)
extension consisted of the Granger Creek Pump Station and approximately 17,600 LF
of both 20 inch and 18" diameter pipe. In 2015, the City extended the interceptor sewer,
continuing along Granger Creek and U.S. Highway 151/61, to the Dubuque Regional
Airport. The GCIS extension increased the sanitary Sewer Shed 4 to approximately
6,300 acres.
Since the GCIS and the extension to the Dubuque Regional Airport has been
completed, several adjacent areas in or near Key West have connected to the City's
sewer system, such as Table Mound Mobile Home Park, Kerrigan Heights Subdivision,
Truck Country, a portion of Twin Ridge Subdivision, and Silver Oaks Subdivision.
Tamarack Business Park and the City's Crossroads Industrial Park, along with other
adjacent parcels, are also able to be served by GCIS.
The City of Dubuque submitted a facility plan, based on the results of an intensive
evaluation of the existing interceptor collection and pumping systems that convey
sewage to the Water Resource Recovery Center (WRRC), to Iowa Department of
Natural Resources (IDNR), in September of 2021. The facility plan identified three
improvement projects related to the Granger Creek Interceptor Sewer System: Granger
Creek Lift Station Capacity Improvements, Twin Ridge Sanitary Sewer Extension and
lagoon abandonment and the Tamarack Sanitary Sewer Extension.
The Granger Creek Lift Station Improvements Project will increase the firm pumping
capacity of the existing Granger Creek Lift Station from 0.5 MGD to 2.9 MDG which will
provide the needed capacity to serve existing and proposed developments within sewer
shed 4.
DISCUSSION
The City selected Strand Associates, as the design consultant, for this project through
the RFP Process. The Granger Creek Lift Station Improvements design is based on the
approved IDNR Facility plan, for the Granger Creek Interceptor Sewer Improvements.
The increased pumping capacity is needed to serve additional areas that are now
served by the original Granger Creek Interceptor Sewer (constructed in 1998) and the
extension of the interceptor sewer to the Dubuque Regional Airport (constructed in
2015). The project will also provide upgrades to the existing Catfish Creek Lift Station.
The installation of the new Granger Creek Lift Station control equipment, within the
Catfish Creek Lift Station Building, will require some minor modifications to electrical
fixtures and the replacement of the existing HVAC system, to be code compliant.
The installation of the new control equipment, for the upgraded Granger Creek Lift
Station, will require the HVAC system to be replaced to ensure proper temperature
control, for all electrical components, and proper ventilation for personnel entering the
building. The new HVAC system will utilize some of the existing roof penetrations, used
by the existing system, but will require modifications to the existing openings along with
additional roof penetrations. The modified and additional roof openings will require the
replacement of the existing roofing system. The existing roofing system is in extremely
poor condition and is not able to be modified to accommodate the changes.
PROJECT SCHEDULE
The schedule for the project is as follows:

specifications, form of contract and estimated cost for the Granger Creek Lift Station
Improvements. I further recommend establishing the date of the public hearing and
authorizing the Engineering Department to advertise for bids.

All three of the projects identified in the facility plan are utilizing State Revolving Fund

Ridge sewer extension projects, are also utilizing SRF loan proceeds for Construction.
The construction of the third project identified in the Granger Creek Facility plan,
Granger Creek Lift Station Improvements, is funded utilizing a combination of a State
Revolving Fund (SRF) loan for a 20% match toward a $1,000,000 grant through the
EPA Community Grants Program.
The Granger Creek Lift Station Improvements project is utilizing the SRF loan program
funding for both design and construction. The SRF loan is being funded through
multiple Fiscal Year appropriations as detailed below:
