INTRODUCTION
The purpose of this memo is to request authorization to release a request for proposals
(RFP) for the Design of the Granger Creek Pump Station Upgrade Project.
BACKGROUND
Over 60 years ago the City of Dubuque started to invest in sanitary sewer infrastructure
to protect the health of its citizens and to serve the growth that had occurred and was
occurring along its western City limits. The Catfish Creek Interceptor Sewer (CCIS) was
constructed in 1956, which allowed the City to extend sanitary sewers to property
owners within the sewershed. The Catfish Creek Pump Station (CCPS) and Water
Pollution Control Plant, now referred to as Water and Recourse Recovery Center
(WRRC), were constructed in the late 1960's. Since the late 1960's, the community has
grown and expanded to the west. The City has invested in renovations and
replacements at WRRC and CCPS to meet state and federal regulations, and to
adequately serve the expanding community.
In 1998 the City began extending sanitary sewer along Granger Creek, to the Dubuque
Technology Park. The Granger Creek Interceptor sewer extension consisted of the
Granger Creek Pump Station and approximately 17,600 feet of both 20-inch and 18-
inch diameter pipe. The pump station was designed to be upgraded as needed to
accommodate growth within the sewershed (sewershed 4). The Granger Creek Pump
Station pumps the flow from the lower Granger Creek Interceptor Sewer up to the
Catfish Creek Pump Station. The Current firm pumping capacity of the Granger Creek
Pump station, is 0.94 million gallons per day (MGD).
The City of Dubuque submitted a facility plan to Iowa Department of Natural Resources
(IDNR) in September of this year (2021). It identified three projects related to the
Granger Creek Interceptor Sewer System. One of the three projects is to upgrade the
capacity of the Granger Creek Pumping Station, from 0.94 MGD to 2.9 MGD. The
facility plan is based on the results of an intensive evaluation of the existing interceptor
collection and pumping systems that transport sewage to the Water Resource Recovery
Center (WRRC).
DISCUSSION
The selected consultant will be expected to complete the contracted scope of work
within a specified timeframe, under the general direction and coordination of the City's
Engineering Department, as authorized by the City Council. The goal is to complete the
engineering design and initiate the public bidding process for construction by July 5,
2022.
