FROM: Michael C. Van Milligen, City Manager
SUBJECT: Minimum Sanitary Sewer Rate Changes for Fiscal Year 2027
DATE: May 13, 2026
Water & Resource Recovery Center Director Deron Muehring is recommending City
Council approval of the ordinance amending Section 13-2C-3(C) of the Code of
Ordinances to adjust the minimum sanitary sewer charges by 9% in support of the
adopted Fiscal Year 2027 Budget.
Following adoption of the ordinance establishing the sanitary sewer rates per 100 cubic
feet and rate per each gallon, staff identified that the minimum sanitary sewer charges
were not adjusted as part of the ordinance amendment. The minimum sanitary sewer
charges should also reflect the same 9% increase adopted for the FY2027 sanitary
sewer rates to fully support the adopted FY2027 budget.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

SUBJECT: Minimum Sanitary Sewer Rate Changes for Fiscal Year 2027
DATE: May 12, 2026
INTRODUCTION:
The purpose of this memo is to recommend modification of Section 13-2C-3(C) of the
Code of Ordinances to adjust the minimum sanitary sewer charges for Fiscal Year 2027.
BACKGROUND:
The proposed FY27 minimum sanitary sewer rate adjustment is necessary to fund the
continued operation, maintenance, and long-term improvement of Dubuque's wastewater
collection and treatment system. This includes the daily operation of the Water &
Resource Recovery Center (WRRC), where wastewater from homes, businesses, and
industries is treated before being safely returned to the environment, as well as the
operation and maintenance of the City's 22 sanitary sewer lift stations and more than
300+ miles of sanitary sewer mains. These fees support essential services such as
treatment, pumping, cleaning, televising, repairs, regulatory compliance, laboratory
testing, odor mitigation, and emergency response.
On April 28, 2026, the City Council adopted the Fiscal Year 2027 budget. Also on April
28, 2026, the City Council adopted an ordinance establishing the schedule of sanitary
sewer rates per 100 cubic feet and rate per each gallon in support of the adopted FY2027
budget. The staff inemo associated with the previously adopted ordinance is attached for
reference. As outlined therein, the proposed 9% increase for FY27 will result in a $2.87
increase in the monthly sanitary sewer fee for the average household in Dubuque, based
on typical usage of 3,200 gallons of water per month as outlined in Table 1 below. As a
user fee, it is based on the amount of water used and corresponding wastewater
generated. For lower consumption households, those that might only use 2,000 gallons
per month, the current fee would be $19.92 per month. This would increase by $1.79 to
$21.71 per month as proposed in FY2026.

DISCUSSION
Following adoption of the ordinance establishing the sanitary sewer rates per 100 cubic
feet and rate per each gallon, staff identified that the minimum sanitary sewer charges
were not adjusted as part of the ordinance amendment. The minimum sanitary sewer
charges should also reflect the same 9% increase adopted for the FY2027 sanitary sewer
rates to fully support the adopted FY2027 budget.
The proposed ordinance amendment will adjust the minimum sanitary sewer charges by
9%, consistent with the sanitary sewer rate increases previously adopted by the City
Council for FY2027.
A marked-up version of the proposed ordinance amendment is attached to clearly identify
the changes proposed to the minimum sanitary sewer charges.
RECOMMENDATION:
I recommend amending Section 13-2C-3(C) of the Code of Ordinances to increase the
minimum sanitary sewer charges by 9% in support of the adopted Fiscal Year 2027
budget.
ACTION REQUESTED
I respectfully request passage of the attached ordinance amending Section 13-2C-3(C)
of the Code of Ordinances to adjust the minimum sanitary sewer charges for Fiscal Year
2027.

TO: Michael C. Van Milligen, City Manager
FROM: Deron Muehring, Water & Resource Recovery Center Director
SUBJECT: Sanitary Sewer Rate Changes for Fiscal Year 2027
DATE: April 23, 2026
INTRODUCTION:
The purpose of this memo is to recommend modification of Sections 13-2C-3(B) and 13-
2C-3(C)(7) of the Code of Ordinances, thereby adjusting the sanitary sewer rates as
proposed with the Fiscal Year 2026 budget.
DISCUSSION:
The proposed FY27 sanitary sewer rate adjustment is necessary to fund the continued
operation, maintenance, and long-term improvement of Dubuque's wastewater collection
and treatment system. This includes the daily operation of the Water & Resource
Recovery Center (WRRC), where wastewater from homes, businesses, and industries is
treated before being safely returned to the environment, as well as the operation and
maintenance of the City's 22 sanitary sewer lift stations and more than 300+ miles of
sanitary sewer mains. These fees support essential services such as treatment, pumping,
cleaning, televising, repairs, regulatory compliance, laboratory testing, odor mitigation,
and emergency response.
The proposed FY27 rate adjustment supports continued reinvestment in aging
infrastructure and system reliability. Planned investments include improvements to
treatment processes, replacement of obsolete controls and equipment, lift station
reliability upgrades, odor reduction measures, and facility planning efforts that will guide
future capital needs. These investments are necessary to maintain dependable service,
reduce the risk of failures, comply with environmental requirements, and position the utility
to meet future community needs.
The proposed adjustment also reflects the increasing cost of providing wastewater
service. Over the past decade, many of the core inputs required to operate wastewater
utilities have risen significantly faster than general inflation. Costs for electricity, natural
gas, chemicals, equipment, and construction have all increased materially, placing
upward pressure on the cost to maintain current service levels. At the WRRC specifically,
electricity costs have increased by more than 120 percent over the past ten years even
though the WRRC has reduced energy use per million gallons treated by approximately
20 percent over the past three fiscal years through improved operations and process
management. These are not discretionary costs—they are the essential inputs required
Scrvicc Pcoplc Intcgrity Rcsponsibility Innovation Tcamwork
Page 859 of 890
to pump wastewater, operate treatment processes, disinfect flows, manage solids, and
maintain system reliability.
The proposed 9% increase for FY27 will result in a $2.87 increase in the monthly sanitary
sewer fee for the average household in Dubuque, based on typical usage of 3,200 gallons
of water per month as outlined in Table 1 below. As a user fee, it is based on the amount
of water used and corresponding wastewater generated. For lower consumption
households, those that might only use 2,000 gallons per month, the current fee would be
$19.92 per month. This would increase by $1.79 to $21.71 per month as proposed in
FY2026.

To ensure rates remain aligned with peer communities across lowa, the proposed rates
are routinely benchmarked against the largest cities in the state that own and operate
their own wastewater treatment facilities. A comparison of the monthly sanitary sewer fee
for the average household is shown in the table below.

6 Sioux Cit $32.87
7 Ames $30.34

*Based on 5/8 Meter & 3,200 Gal
The average fee in Dubuque is 14.6% lower than the highest fee. And the average of the
other cities is 9.6% lower than the fee in Dubuque.
A comparison of average annual rate increases from FY20 to FY27, Dubuque's proposed
9% increase will result in an average annual rate increase of 6.4% over the period—
ranking it fourth highest (or fifth lowest) among the peer cities analyzed as reflected in
Table 2 below. While slightly above the group average of 5.2%, the increase reflects the
Scrvicc Pcoplc Intcgrity Rcsponsibility Innovation Tcamwork
Page 860 of 890
scope and scale of the planned infrastructure improvements, some of which are already
under construction.

5 Waterloo 5.8%

7 Daven ort 2.1%

Dubuque
Additionally, the composition of sewer revenue by user class can vary significantly from
city to city. In Dubuque, residential users account for approximately 52% of sanitary sewer
revenue, while industrial users contribute about 25%. In some peer communities,
industrial users may represent a larger share of the overall revenue, which can help offset
costs and reduce the financial burden on residential ratepayers. The breakdown is shown
in Table 3 below.
Table 4. Breakdown of sanitary sewer fee revenue by customer classification for FY2025 through March 25,2025.
Customer Percent Revenue
Classification Contribution
Residential 52%
Industrial 25%
Commercial 22%
Other 1%
Every dollar generated through sanitary sewer fees is reinvested directly into wastewater
collection and treatment systems. The proposed FY27 adjustment will help ensure the
City can continue providing safe, reliable, and environmentally responsible wastewater
service while responsibly addressing aging infrastructure, rising operating costs, and
future system demands.
RECOMMENDATION:
I recommend amending the City Code of Ordinances to increase the sanitary sewer fees
by 9% in support of the proposed Fiscal Year 2027 budget.
