MEMORANDUM
TO: Honorable Mayor and Members of the Common Council
FROM: Stephan M. Brand, Public Works Utility Bureau Manager
DATE: June 7, 2018
RE: Approve Engineering Services Agreement for
Contract 18-16 Wastewater Treatment Plant (WWTP) Digester Mixing System Upgrade /
Donahue & Associates, Inc. (Donahue) ($99,210)
BACKGROUND
The WWTP uses Anaerobic Digestion as part of the wastewater treatment process. This process was installed in
1994 as part of a plant upgrade project. A digester gas mixing system was originally installed with the project.
Over time, that system has lost efficiency and requires high levels of maintenance and energy use to keep it in
operation. This project will replace that system with a more efficient and maintenance -friendly mixing system. The
Digester Mixing System Upgrade project was identified as a high-priority project in the wastewater system asset
management plan completed in 2017.
ANALYSIS
Public Works staff issued a Request for Proposals to engineering consulting firms with the qualifications and
experience to evaluate digester mixing system alternatives and design a mixing system upgrade. Staff reviewed
the four (4) proposals received on a quality -based system to determine how well the proposals demonstrated the
firm's understanding of the project based upon the City's Request for Proposals and the site visits conducted during
the proposal stage. Two (2) firms rose to the top, based upon the quality of the proposals received. The proposed
level of effort and project cost were then factored into the design -making process, leading to the recommendation
of Donahue for this project.
FISCAL IMPACT
The Major Equipment Section of the 2017 Capital Improvement Program budgeted $300,000 for the design of this
project.
RECOMMENDATIONS
Chapter 12 of the Municipal Code of the City of Oshkosh provides that professional services of a specialized nature,
including engineering services, may be procured without the use of formal, sealed quotes. I have reviewed the
proposal and in accordance with Section 12-16 of the Code, I am hereby recommending the Common Council
approve this agreement.
Approved,

South Shore's anaerobic digester complex has
undergone multiple changes over the past 30 years
The digesters have been cleaned three times each,
and piping and equipment was added and
modified to transfer digested sludge to the Jones
Island WRF and to help mix the bottom cone area
of the digesters. The digester gas collection and
monitoring systems were modified and improved.
The facility has six active single -stage, high rate
anaerobic digesters. This includes four large
digesters (125 -foot diameter x 38 feet deep) and
two smaller digesters (1 10 -foot diameter x 21 feet
deep). The four large digesters used a compressed
digester gas draft tube (Atara) mixing system. The
two smaller digesters have four top -mounted draft
tube style mechanical propeller mixers. Both
digester mixing systems provide poor mixing,
resulting in a low volatile solids reduction rate
(VSR). Due to the poor mixing, the digesters' ability

to receive high strength waste and the benefit of
co -digestion would be limited if not prohibited.
Although the anaerobic digesters
have operated without upset, their
performance has been poor and
the volatile solids destruction was
only around 40%. Much of the poor
performance was attributed to the
ineffective mixing. Digester mixing
technologies have improved
dramatically in the past decade,
but mixing a digester that normally
contains hair, rags, grit, sand, and
debris is still very challenging.
Donohue evaluated the digestion process and
digester mixing alternatives.
The evaluation led to a Phase I Mixing
Improvements Project. Mixing systems were
constructed in two of the large digesters: linear
motion mixing in Digester 10 and pump and nozzle
mixing in Digester 12. The digestion performance in
these digesters was tested and evaluated over
several months and compared to the performance
of a poorly mixed digester. The results (see table
below) showed similar performance with each
mixing system although the linear motion mixing
system uses less energy. The project also evaluated
the reliability of the linear motion mixing system.
The system was the largest for the manufacturer
and uses three mixers (one mixer is the standard
design).

Fort Wayne's anaerobic digestion process includes
six 90 -foot diameter digesters that operate in the
mesophilic temperature range. Donohue &
Associates provided preliminary engineering to
evaluate the anaerobic digestion system. Donohue
addressed various issues associated with the system,
including an evaluation of digester mixing
alternatives.
The 90 -foot diameter, 27 -foot side water depth,
186,000 ft3 effective capacity of Digester No. 6
was taken out of service in 1996 due to a failing
cover. The replacement of the cover sparked an
investigation into the best mixing alternative for the
application.
Three alternatives for mixing the digester contents
were evaluated for upgrades to Digester No. 6:
compressed gas mixing, jet mixing, and mechanical
draft tube mixing.
The evaluation for Digester No. 6 showed that the
gas mixing system proposed the lowest present
worth cost, followed by jet mixing, and mechanical
draft tube mixing presenting with the highest
present worth cost.
Several workshops were held with City and plant
personnel to obtain their concerns and desires
regarding the design. Throughout these workshops,
Donohue was able to provide the City with
equipment and control strategies that fit the intent
of digester control and operation. After several
workshops with the Client and the Plant Staff, the jet
mixing technology was chosen due to the biological
benefits and the ease of maintenance.
The first phase of the overall improvements to the
Digester Complex mainly included the upgrade to
Digester No. 6. A new gas holder cover was
provided which increased digester gas storage on-
site and provided a
method of equalizing {
gas pressure in the -r
system. A new jet

sediment traps and connections for Digesters No. 3
and 4.
After the upgrades to Digester No. 6 were
complete, upgrades to the entire gas handling
system for the remaining digesters was considered.
Due to safety concerns, all digester gas piping
(ductile iron, steel, and fiberglass reinforced),
throughout the Digester Gallery and tunnels was
replaced. Construction of improvements to the
existing digester gas handling system included
provision of a new digester gas piping and valve
system, new combination pressure relief/vacuum
breaker safety valves on existing digester covers,
new condensate/sediment traps, and other digester
gas handling components. Construction required the
shutdown and tie-in to the existing digester gas
handling system.
The construction sequences and constraints allowed
the Plant to safely continue digestion operations
during construction. The constraints included the
number of digesters allowed to be taken out of
service at the same time (single digester shutdown
or multiple digester shutdown) and the duration
allowed for these shutdowns. Owner and Contractor
responsibilities during these shutdowns were
specified.

Faced with increasing flows, aging infrastructure
and the inability to meet new regulatory limits, the
City retained Donohue to provide planning, design
and construction services to address the facility's
needs for a 20 -year planning period. The resulting
plant improvements increased average day
treatment capacity from 3.3 to 3.9 mgd and
addressed plant needs and deficiencies. Key
improvements included:

The City of Sun Prairie upgraded its 2.6 mgd
rotating biological contactors (RBC) plant with
tertiary filters and anaerobic digestion to a
3.6 mgd average, 16.7 peak biological
phosphorous removal activated sludge plant.
Donohue teamed with a local firm to provide the
overall recommended plan, design, and construction
of the plant upgrade including a conversion to
activated sludge treatment incorporating biological
phosphorus removal. Waste activated sludge
thickening on a gravity belt thickener prior to
anaerobic digestion minimizes volumetric loadings to
the digestion process and minimizes sidestream
phosphorus loads back to the biological phosphorus
removal process. The thickened waste activated
sludge is anaerobically digested along with primary
sludge.
To maximize digestion capacity and efficiency, the
existing secondary digester was converted to a
second primary digester, and pumped nozzle
mixing systems were installed in each tank for
complete mixing of their contents. In addition, the
digester complex is designed to accommodate
additional future facilities for Class A sludge
production by means of Temperature Phased
Anaerobic Digestion (TPAD).
kr '• 0wo Some of the digester gas is
used in a microturbine;
i however, most is used to heat
the digesters. Donohue
upgraded the gas handling
system and provided space
for additional microturbines in
the future as digester gas becomes available.
Other work included the replacement of the
electrical distribution and controls system. The
ventilation systems were upgraded to meet
NFPA 820 code requirements in process areas.
Net Zero Every Day: Co -Digestion to

Recovery Facility
City of Stevens Point, Wisconsin
Mike Gerbitz ✓ Jeremy Cramer

✓ Bill Marten Dave Goecks
✓ Joe Berktold
The City of Stevens Point owns and operates an
enhanced biological phosphorus removal activated
sludge water resource recovery facility (WRRF) that
discharges to the Wisconsin River. The plant has an
average day design flow capacity of 4.55 mgd
with an 11.8 mgd peak flow.
Gas production from the plant's digesters had been
exceeding fuel demands and, as a result,
approximately 53,000 cubic feet per month of
digester gas was being wasted to flare. The City's
Biosolids and Biogas Utilization Facilities Plan
prepared by others recommended using excess
digester gas to produce energy by combustion with
a 330 -kW engine -generator.
Donohue was selected to provide design services
for this system. During the preliminary design, a
review of plant loadings data found a significant
error between metered digester gas production
and theoretical digester gas production. At
Donohue's recommendation, the plant installed a
new digester gas flow meter which showed that
IDO N O H V E ■ Statement of Qualifications — 13 ■
■ 4.27.2018 1 City of Oshkosh WWTP Digester Mixing System Upgrades ■
actual digester gas produced was almost 50% less
than the Facilities Plan values.
At this reduced digester gas generation rate, the
originally proposed engine would have been
oversized and it may never have been capable of
running. Instead, Donohue designed the installation
of a 1 80 -kW engine -generator.
To further maximize the return on investment of the
engine -generator installation and increase energy
savings, Donohue recommended the City pursue
additional sources of high strength waste to increase
digester gas production.
To accommodate the high
strength waste, Donohue
designed the conversion
of an existing secondary
digester into a primary
'.:
digester. The digester has
ti—
a 50 -foot diameter with
a volume of
approximately 310,000
gallons.
The City selected a linear motion mixing system over
a pump and nozzle mixing system based on
anticipated lower energy consumption. Donohue's
design of the linear motion mixer on the existing
spiral guided gas holding cover is the first
installation of its kind. The cover was inspected,
rehabilitated, sandblasted and painted.
Donohue also designed a pump -nozzle mixing
system for a high strength waste receiving tank.

✓ Joe Berktold
Sheboygan's regional wastewater treatment facility
has been co -digesting high-strength industrial
wastes since 2005. Donohue has provided several
studies for enhancing biogas production and
beneficial reuse. The studies included micro -turbines,
engine generators, digester mixing, temperature -
phased digestion, and acid -methane digestion. The
City has implemented a number of these
alternatives, including the rehabilitation of digester
covers, digester mixing improvements, and biogas-
fueled micro -turbines.
The City wanted to improve volatile solids
destruction and biogas generation in three unmixed
primary digesters by installing new digester mixing
equipment. Each tank is 70 feet in diameter with a
volume of 750,000
gallons. Three
different mixing
technologies were
initially evaluated:
pumped jet mixing,
draft tubes, and linear
motion mixing. The
relatively higher capital cost and energy
requirements for the jet mixing system led to its
early elimination by the City. The draft tube mixers
and the linear motion mixers were both bid as
competing alternate designs.
The City ultimately selected linear motion digester
mixers over draft tube mixers due to their lower
installed cost and energy requirements. This newer
mixing technology provides excellent mixing while
consuming 50% less power than traditional draft
tubes.

WDNR Experience
Donohue is a Wisconsin -based, wastewater -focused
specialty firm. As such, we have a long successful
history of working with the Department of Natural
Resources (WDNR). Our Project Manager, Mike
Gerbitz, began his wastewater career working as
an Area Wastewater Engineer with the WDNR.
Mike Gerbitz, Bill Marten, and Jeremy Cramer all
have direct first-hand experience working with the
Department throughout their 20+ year wastewater
careers. As such, they are well versed on the
relevant NR Codes, WDNR personnel, and the
WDNR approval processes.
If improvements are limited to mixing system
replacement, the Department and assigned
reviewers will likely view this Project as a simple
maintenance Project. As such, a formal review and
approval is not necessary, assuming you do not
intend to use funding from the Clean Water Fund.
Nevertheless, Donohue invariably submits the plans
and specifications to the Department for their
records and the public record. We recommend the
same for this Project. If proposed improvements add
a process, modify a process, or adjust capacity, the
WDNR requires a formal submittal and approval
prior to bidding.
The adjacent list demonstrates some of our
experience submitting to the Department and
receiving WDNR approval. Donohue typically
receives plan and spec approval from the WDNR
without any comments or required revisions. Recent
notable examples include the $45M major upgrade
for the City of Eau Claire, the $25M major upgrade
for the City of Whitewater, the $1 OM digestion and
drying system improvements for the City of
Kenosha, and the $15M digestion and drying
system improvements for the City of Sheboygan.

Design Process
This Section describes the measures the Donohue
Team will use to deliver accurate and reliable
Bidding Documents that define the construction
Work consistent with the City's understanding and
expectations.
Project Manager
Project success lies at the intersection of quality,
schedule, and budget. The Project Manager is
responsible for directing the Team to arrive at that
intersection. For this Project, Mike Gerbitz will be
our Project Manager. He is one of our most
experienced and accomplished project managers
with a strong record of delivering successful
projects, including the project we feature in this
Proposal (Eau Claire, WI).
Engineers and Operations
Specialists
The quality of the Bidding Documents is directly
linked to the talent and experience of the design
engineers producing those Documents. The
operating performance, reliability, and resiliency of
the process systems defined in the Bidding
Documents is directly linked to the talent and
experience of the process engineers and operations
specialist formulating those process systems. We
selected our Project Team with these linkages in
mind.
Our Project Team averages more than 20 years of
directly -related experience. Collectively, Bill Marten
— Lead Process Engineer, Jeff Wills — Lead
Mechanical Engineer, and Jeremy Cramer — Lead
Operations Specialist possess more than 80 years
of anaerobic digestion and biogas systems
experience. Quality hinges on the talent and
experience of critical Team members. We have
assembled an exceptionally talented and
experienced Team.
The Donohue System
As a specialized wastewater -focused engineering
firm, Donohue has developed a formal Design
Workflow with strategically -timed collaborative
and interactive workshops/meetings; well -
conceived, high-value deliverables; cost opinions;
and quality review points. This Workflow has
proven effective at fostering collaboration,
enhancing efficiency by performing tasks in the
proper "first things first" order, performing multiple
quality reviews throughout the design, and
delivering high-quality Bidding Documents in
accordance with the allowable time and budget.
This Workflow, tailored slightly for the unique
requirements of this Project, is shown in Figure 1 .
Designer Field Review
The Workflow denotes important events: the 60% -
and 90% -complete "Plans -in -Hand" Field Reviews
by the design engineers. These reviews are exactly
what the name implies: our lead engineers take the
design drawings in the field at these milestones to
field -verify existing conditions, confirm removals are
accurately denoted, review potential interferences,
and review construction sequencing. We're proud of
our commitment to these field reviews and are
convinced they enhance the quality of our Bidding
Documents.
Quality Reviews
Figure 2 shows that quality reviews will be
performed at the completion of each design stage
before proceeding to the next. The reviews will be
performed by three of our most talented,
experienced, and accomplished engineers: Phil
Englebert, Gary Cressey, and Dennis Dineen. They
possess more than 130 years of combined
wastewater design experience.

A decade ago, the City of Eau Claire operated a
regional wastewater treatment facility designed to
treat an average flow of 16 million gallons per day
(mgd) which had been de -rated to 11.5 mgd due to
its Rotating Biological Contactor (RBC) secondary
treatment process. The RBCs had numerous
challenges and were considered at the end of their
useful life.
Donohue provided the City with a 20 -year facilities
plan to upgrade the existing wastewater treatment
plant and two major lift stations. The facilities plan
recommendations were prioritized into two phases
for implementation, a lower cost first phase to meet
the City's immediate needs while delaying a more
extensive $30+ million second phase upgrade to
allow the City time to financially plan for it.
The first phase addressed the most critical needs of
effluent ammonia compliance and biosolids storage.
Donohue designed these improvements that came on
line in late 2008.
The second phase project included improvements to
the liquid and solids treatment train to address
other issues and upgrade the facility to meet the
challenges of future growth and regulatory
compliance. The existing RBC system was replaced
with an advanced biological nutrient removal
(nitrogen and phosphorus) activated sludge system
with innovative energy conservation features. The
improvements also included significant
upgrade/rehab of the plant's existing final
clarifiers, significant expansion and upgrade of the
plant's laboratory facilities, implementation of an
advanced SCADA automation and monitoring
system, and addition of significant odor capture
and control facilities.
Solids handling upgrades addressed existing issues
and new facilities, and included:
A third gravity belt thickener for waste
activated sludge (WAS), and new thickened
WAS and thickened digested sludge pumping
systems
Anaerobic digestion upgrades including energy
efficient linear motion mixers, jet nozzle
pumped mixing, and digester pumping/heating
system upgrades
Thickened biosolids storage upgrades including
a new jet nozzle pumped mixing system
Digester biogas system improvements including
new gas cleaning systems (for foam separation
and 1-12S, moisture and siloxane removal) and
new boilers and engine -generators (with heat
recovery) fueled using biogas
The second phase upgrades were completed in late
2014 and fully operational in early 2015. The
result has been the ability to go from around-the-
clock (three shifts) to single shift operations while
greatly enhancing the plant's data collection and
laboratory functions.

12/31/2015 emaiL excerpts
Thanks for all your help with making our
treatment process work optimally. Dealing
with effluent results that have been near our
regulatory limits for so long it is nice to
see how low we can go. Last month our
efficiency for BOD and TSS were 97.4% and
98.2% respectively, and that was down from
our best ever of 98.8% and 99.2% earlier this
year. I look back at the genesis of this
project, which started over 10 years ago, and
to be where we are today is rewarding.
Donohue & Associates has obviously been a
significant part of this success, and I am
extremely satisfied with our choice in
engineering consultant for these projects.
Donohue has all of the expertise required for this project in-house. At his time we do not anticipate needing
site survey services. If those services are required, we will subcontract with a local surveyor approved by the
City.

4.27.2018 City of Oshkosh WWTP Digester Mixing System Upgrades
Project Approach
Project Understanding
The City of Oshkosh has provided effective
wastewater treatment for nearly 100 years. The
current regional wastewater treatment plant (Plant)
is now in its 5'" decade of operation. The Plant was
designed to treat an average -day flow of 35 mgd.
Today it receives and treats roughly 40% of this
design rating. Plant processes are oversized and
underloaded, and certain facility limitations
magnify the challenges inherent with operating an
oversized facility. Plant staff have met these
challenges, reliably producing permit -compliant
effluent while striving to minimize costs.
With an eye to the future, the City has developed a
stepwise improvement plan to remedy operating
and performance challenges. This Project is one of
the steps outlined in that plan: improving the
anaerobic digestion process. This Project will also
seal the step -feed boxes in the aeration basins.
Anaerobic Digestion Elements
The main purpose of this Project is to replace the
gas mixing system in the primary digesters with one
that enhances performance, operability, and
maintainability.
The existing gas mixing system is more than
20 years old, exacerbates foaming problems, and
is marginally effective when it is used to mix the
primary digesters. Because of foaming and poor
performance, the Plant staff does not operate the
gas mixing system in the two primary digesters
(Digester 1 and 2). The staff uses the gas mixing
system in the secondary digester/digested sludge
holding tank (Digester 3) to produce a consistent
and stable blend of digested sludge to the biosolids
dewatering process.
Because the Plant and digestion complex is
underloaded, the existing primary digesters
perform well, reliably providing good volatile solids
destruction and a steady supply of biogas for Plant
heating and the engine generator at the University
of Wisconsin -Oshkosh (UWO) biomass digester.
The lack of primary digester mixing does add
operating and maintenance challenges. One of the
more significant problems is a significant
accumulation of debris and scum at the upper levels
of the primary digesters. The debris load is
attributed to the effective size of the preliminary
fine screens, a lack of fine biosolids screening, and
a large debris load from street sweeping and
sewer -cleaning material accepted at the Plant. The
scum originates largely in the liquid treatment train.
Without effective primary digester mixing, biogas
attaches to these materials (debris and scum) and
causes it to float to the digester water surface. The
result, over time, is a buildup of 5 +/- feet of scum
and debris, which the Plant staff remove roughly
every five years by taking each digester out of
service for a thorough cleaning and inspection.
The Project will also provide structural repair to the
concrete and brick exteriors of the digesters. Years
of freeze -thaw cycles have taken their toll, causing
bricks to come loose.
Activated Sludge Elements
As part of its long-term plan to optimize the
operability and flexibility of the Plant's activated
sludge system, one of the elements of this Project is
aimed at eliminating the step -feed gates on the
aeration basins. These gates were part of the
original activated sludge system design, which back
in the 1970s, aimed to provide extreme
operational flexibility. During that era, many plants
were designed so they could be operated in a
plug -flow, step -feed, or contact -stabilization mode.
Experience has shown plug flow, with possible
provisions for biological nutrient removal (BNR),
sometimes with high-flow partial step -feed (in a
different configuration than the current one) provide
for optimal activated sludge treatment. The Plant
has never been operated in the step -feed mode.
This Project will eliminate the step -feed gates.
Anaerobic Digestion Approach
For decades, the wastewater treatment industry has
been considering and developing strategies and
designs to more effectively mix anaerobic digesters.
The marketplace continues to see new mixing
technologies.
DONOHUE Statement of Qualifications -20
■ 4.27.2018 1 City of Oshkosh WWTP Digester Mixing System Upgrades ■
Decades ago digesters were mixed with simple
propellers. Simple propellers evolved to internal
draft tubes. Then came the gas -mixing lances era,
which located all moving parts outside the digester
to enhance maintenance and accessibility. This style
of gas mixing, however, caused foaming. Foaming
led to external draft tubes, which are more
accessible than cover -mounted draft tubes, but also
reversible and, in some instances, equipped with
digester heating water jackets. Reversing external
draft tubes specifically addressed surface foam
and scum accumulation.
Gradually, over time, external draft tubes gave
way to pumped -nozzle mixing and variations of
concentrated or confined gas mixing (shearfusers
and large -bubble cannons). These systems provided
all moving parts at grade and outside the digester.
And most recently, the industry has embraced linear
motion mixers that provide steady, low-energy
mixing via an oscillating plunger installed at the
center of a circular digester. Real world lessons are
summarized below.
❖ Internal Draft Tube Mixing — Good mixing
performance. Moderate energy efficiency.
Vertical geometry limits water surface
variability. Roof -mounted. Poor equipment
access. Potential for reversing action to provide
surface agitation that breaks up surface scum
and foam. Relative capital cost is high.
❖ External Draft Tube Mixing — Good mixing
performance. Moderate energy efficiency.
Vertical geometry limits water surface
variability. Installed on digester periphery.
Digestion complex configuration may preclude
installation. Poor equipment access, but better
than internal draft tubes mounted in the center
of the roof. Potential for reversing action to
provide surface agitation that breaks up
surface scum and foam. Relative capital cost is
high.
❖ Gas Mixing — Generally being phased out of
the wastewater industry. Mixing performance
fails to realize the full capacity of the digestion
volume. Potential for localized problems like
struvite formation where the gas enters the
digester. Accommodates variable water surface
elevations. Good equipment access. Potential to
exacerbate foaming. Poor incorporation of
floating scum and foam. Relative capital cost is
low to moderate.
❖ Pumped -Nozzle Mixing — Widely employed
today for digester and sludge storage mixing.
Experience has revealed how to better operate
and control these systems when employed for
digester mixing. High -velocity nozzles offer a
unique ability to re -suspend deposits. Unless
equipped with variable frequency drives, this
high-intensity advantage can be a
disadvantage as too much mixing intensity can
exacerbate foaming issues. The wastewater
industry has learned, first by discharge valve
throttling and then by way of VFDs, how to
optimize this high-intensity mixing system. Many
facilities have elected to operate these mixing
systems intermittently. Moderate energy
efficiency when operated with a VFD or
intermittently. Good equipment access. Potential
for surface discharge to better entrain floating
scum and foam. Relative capital cost is high.
❖ Linear Motion Mixing — The most recent digester
mixing advancement. Over the last 5 to 10
years, this technology has proven to be an
acceptable and often preferred mixing
alternative. The consistent, 247 operation of
such low-energy mixing was first viewed
skeptically, but industry testing has
demonstrated that these simple, low-energy
systems provide good performance. Donohue
designed mixing system improvements for
several digesters at the Milwaukee
Metropolitan Sewerage District's South Shore
digestion complex. One digester was equipped
with linear motion mixing, the other pumped -
nozzle mixing. The side-by-side test results are
shown in Figure 3.
The District has elected to install linear motion
mixers in their remaining primary digesters. Full-
scale installations have confirmed that linear
motion mixers effectively mix digester volumes
and achieve similar digestion performance
levels as other mixing technologies, at a fraction
of the energy input. The challenge can be in
their installation: floating, variable level covers
being an issue, but one that can be overcome.
Roof -mounted equipment hinders accessibility.
No direct surface agitation to break up surface
foam and scum. Relative capital cost is low to
moderate.

Figure 3 — Full -Scale, Side -by -Side Digestion Results at

Donohue designed digester mixing systems for the South
Shore WRF: one linear motion mixing system and one
pumped -nozzle mixing system. The test results showed linear
motion mixing consumes less energy input per unit of volatile
solids destroyed (or energy output). The District has elected
to installed linear motion mixers on their other primary
digesters.
The Donohue Project Team has extensive experience
with all of the above digester mixing technologies.
We've seen them come into the market, seen them
evolve, and seen the results. We've evaluated them,
we've tested them, we've operated them, and
we've designed them. We can confidently say that
the Donohue Team, the specific engineers and
operations specialists assigned to this Project, all
located in close proximity to Oshkosh, bring an
exceptional and unique level of real-world
experience with all of the potential mixing
technologies. Moreover, we can confidently say that
these talented and experienced engineers and
operations specialists will work closely and
collaboratively with the Plant staff to deliver the
"right" system, as the City and Donohue choose to
define the "right" balance of performance,
efficiency, operability, maintainability, and cost.
From our site visits and discussions with you, we feel
you've picked the right mixing technologies for
consideration: draft tubes, jet mix, and linear
motion. Many considerations will factor into defining
the right technology for the Oshkosh Plant. The
foundation of our approach to this Project is a
comprehensive and highly collaborative evaluation.
The product of that evaluation is information.
Information the City needs to select the "right"
mixing system.
The right technology isn't always a single
technology. Our Eau Claire project provides an
example of this. For that project, linear motion
mixing was the right technology for the smaller,
primary digesters, and pumped -nozzle mixing was
the right technology for their larger secondary
digester.
All areas in a treatment facility, in one form or
another are connected. Factors beyond the digester
will be considered, factors from other parts of the
Plant. Our Team's experience, and in particular that
of our people with first-hand operations
experience, bring a plant -wide perspective to these
evaluations and decisions. The City will live with the
mixing decision for the next 30-40 years. The
decision must be well thought-out and broadly
considered. Our engineering and operations Team
will help you do that.
Debris loading is one example of a whole -plant
challenge that might be worth considering as part
of this digester mixing evaluation. Debris gets into
the digesters now, it will get into them in the future,
and debris can cause problems with any mixing
system (some more so than others). As part of our
evaluation, we'll include approaches to address this
debris issue, to get it out and keep it out. We'll
look at strategies to do that with the current Project
or as a future improvement. Possible solutions
include enhanced preliminary screening, with new
screens or a cost-effective retrofit to your current
screens, better street -sweeping and sewer -cleaning
debris management, or strategic sludge -stream
screening. Figure 4 shows a simple street -sweeping
and sewer -cleaning debris acceptance and
management system we designed for the Fox River
Water Pollution Control Center (Brookfield, WI).
We know debris is a problem, and together we can
find good solutions to getting it out and keeping it
out.
Other examples include inter -related digester
modifications to optimize your process. This Project
might be the time to consider more holistic digestion
system matters like those discussed below and
illustrated in Figure 5.
❖ Passive overflows from the primary digesters to
the secondary digester, maximizing digestion
volume, efficiency, and operational simplicity,
while eliminating scum and foam trapping and
accumulation;
DQNQHUE Statement of Qualifications -22
4.27.2018 City of Oshkosh WWTP Digester Mixing System Upgrades
❖ Operating the secondary digester as a primary
digester during periods when one of the
primaries is out of service;
❖ Alternative robust digester feeding strategies,
both during normal conditions and atypical
conditions;
❖ Fixing the primary digester covers to the
sidewalls and extending the skirt lengths to
better accommodate roof -mounted mixing
technologies, passive overflows, and liquid level
variability; and/or
❖ Replacing the secondary digester mixing system
with a more robust or effective technology.
We know the above items are not specifically
required in your Scope of Services; however, we
feel this Project might be the right time to consider
these matters and, at a minimum, develop the
"right" long-term plan for the digestion complex.
Improvements beyond the mixing system could be
added to the design phase of this Project or
deferred to a future phased implementation. This
Project will provide the capital costs or budgetary
placeholders required for future capital planning.
Figure 4 - Street -Sweeping and Sewer -Cleaning Debris
Acceptance and Management System. Donohue worked
with the City of Brookfield, WI to design this simple system
to receive, contain, and dewater street -sweeping and
sewer -cleaning debris. This system can also be used to
accept and receive FOG and debris removed from
wastewater pumping stations. The disposable fabric allows
water to drain out, but prevents debris from recycling to the
Plant. When dry, the City has the material hauled to a
landfill.
Our approach to the digester mixing component of
this Project, and the Project as a whole, is to use a
highly experienced, Wisconsin -based, Team of
engineers and specialists to work closely with you to
effectively evaluate alternatives and help you make
well-informed and well -conceived decisions for the
Plant and its future. Our proposed Team
understands the technologies and how they and
digestion "fit" within the whole Plant. Our Team has
operated digestion complexes and mixing systems.
This unique and important perspective will help
ensure that the improvements advanced to design
and construction will strike the right balance
between simplicity, operability, maintainability and
flexibility for the future.

Phase of this Project. The purpose is to help the City
develop, not only the right mixing strategy, but also the
right long-term digestion complex plan.
Biogas Utilization Approach
Biogas produced by the digestion process can be
burned in three end uses: boilers at the Plant
(Boilers), an engine at the University of Wisconsin -
Oshkosh (UWO), and the flare at the Plant (Flare).
Biogas flow to these different end users is controlled
with pressure -controlled, mechanically -actuated
diaphragm valves. The operating pressure range
for the biogas system accommodates release to the
UWO, the Flare, and the safety relief valves to
Do N o H U E Statement of Qualifications - 23
4.27.2018 City of Oshkosh WWTP Digester Mixing System Upgrades ■
atmosphere. The relatively poor sensitivity of the
mechanical valves makes it difficult to operate or
control these end uses within the available pressure
range, resulting in undesired biogas flow to lower -
priority end uses.
During the evaluation phase of the Project, we look
forward to discussing and potentially evaluating
with the City an alternative biogas utilization control
system that will address the current pressure -related
stability challenge. Rather than using a pressure -
based control strategy, we have successfully
employed a cover -height control strategy that
allows the biogas system to operate at a constant
pressure. This simple strategy has proven stable and
reliable. A simple schematic is shown in Figure 6.
We envision the end-use priority being 1 - the
Boilers, 2 - the UWO, and 3 - the Flare. The boiler
system would get biogas flow irrespective of the
cover position. As biogas accumulates and the cover
rises to operator set -points, electrically -actuated
valves would modulate sequentially allowing only
the desired amount of biogas to flow to the UWO
and then the flare.

Figure 6 - Cover -Height Biogas Control Strategy. Rather
than using pressure to control biogas end use, this strategy
uses the position of the cover, relative to the water surface,
to define the biogas end users. The biogas system then
operates at a relatively constant pressure. We successfully
employed this strategy at the Fort Wayne Water Pollution
Control Facility.
Step -Feed Channels Approach
At first glance, blocking off the old step -feed
channels is relatively straightforward. But our
whole -Plant understanding, and in particular our
understanding of activated sludge systems and how
to optimize them for normal and extreme wet -
weather events, will allow us to help you with some
initial thoughts/planning related to future activated
sludge improvements. In particular, as we evaluate
blocking off these channels, we will work with you to
consider how your two parallel activated sludge
trains can be optimized down the road, to best
meet current loadings while also being adept at
handling current wet-weather/peak flow periods
without sacrificing performance. And how the trains
and any planned future modifications will lend
themselves to future changed conditions, such as new
unplanned for loads, or how best to handle
phosphorus - continued chemical, biological, or a
mix - and how each fits into digestion, dewatering,
and other plant considerations.
We know one key will be making all four of your
secondary clarifiers available for either aeration
train, but other considerations may include things
like selector zones for filament/SVI control or BNR,
or high-flow step -feed in an alternate configuration
from the Plant's original design. Again, our Project
Team brings significant experience in all of these
aspects. While this is a small part of this Project, we
feel it's an important added element to the service
we will provide.

experienced person, not a committee. Our Project
Manager, Mike Gerbitz, will be the person
responsible for leading the Donohue team to satisfy
City requirements and preferences, coordinating
between the City and the Donohue Team, and
keeping the City well informed of Project progress
and issues. The methods he will use are briefly
discussed below.
Communication
Mike Gerbitz, our Project Manager, will be the
primary conduit for communications from the City to
Donohue and from Donohue to the City. As design
progresses, Donohue and the City may establish a
communication protocol that allows designers to e-
mail City staff directly; however, the protocol will
require Mike Gerbitz be copied.
Monthly Status Reports
Each month, Mike Gerbitz will prepare and provide
Status Reports that accompany our invoices. The
format of these Reports will be specifically tailored
to the City's requirements. Before submitting the first
Report, Mike will work with the City to establish the
format. An example three-page Status Report is
provided after this page. This Status Report was
Proposed Fee
Our proposed fee is itemized on the next page.
We developed this fee consistent with the Scope of
Services outlined in this Proposal.
The Design Phase fee assumes the Bidding
Documents will define Work associated with a new
external draft tube mixing system. This fee may be
adequate for other mixing systems; however,
depending on the specific mixing system and
required ancillary improvements associated with it,
the fee may need to be revised slightly.
prepared for a project Mike is currently managing
with the Western Lake Superior Sanitary District.
[For that project, Bids were opened April 12, 2018.
The Donohue estimate was $1 8.35MM. The three
bids were $16.98MM, $18.35MM, and
$19.45 MM.]
Progress Meetings
We propose to conduct six Progress Meetings and
one Workshop. The purpose of the Meetings is to
discuss relevant Project -related administrative,
technical, and operational matters, and review work
products in various stages of completion. The
primary focus of these Meetings is to foster
collaboration and information sharing; however,
they will also provide the City an opportunity to
review our progress.
E -Mail
The City and Donohue will establish communication
protocols at the Kickoff Meeting, including the
Owner and Donohue personnel that will receive
important e-mails. Communications worthy of the
Project archives will be sent to the Project e-mail list.
The Subject line of each e-mail will include a pre-
defined Project identifier (e.g., Oshkosh — DIGMIX —
subject) to help all parties search and organize
Project e-mails.
In addition to our fee worksheet, the next page also
includes some metrics that we think provides
relevant perspective.
We want to work with the City of Oshkosh on this
important Plant project. If you have any questions
related to this fee proposal or require additional
information, please contact our Project Manager,
Mike Gerbitz, 920-889-4000 or
mgerbitz@donohue-associates.com.

Wastewater Treatment Facility Improvements, Faribault, Minnesota. Project Manager:
Donohue designed a wastewater treatment facility upgrade for this rapidly growing
community of approximately 20,000 people with two large food production industries. The
treatment facility consists of the following unit processes: raw wastewater screening, raw
wastewater pumping, aerated grit removal, primary settling, fixed -film roughing filters,
activated sludge, secondary settling, gaseous chlorine disinfection, de -chlorination, primary
sludge pumping, waste activated sludge thickening, anaerobic digestion, liquid biosolids
storage, and roughing filter ventilation with odor control. The upgrade included new RAS
and WAS pumping; new aerated WAS storage; new WAS thickening structure with a 2-M
gravity belt thickener; anaerobic digestion system improvements complete with new heating
system boilers and heat exchangers; liquid and gas piping improvements, NFPA 820 code
compliance, digester mixing, and a gas -holding digester cover.
Biosolids Evaluation, Sioux City, Iowa. Project Manager: Currently evaluating several
improvements to biosolids processing at the 16-mgd Sioux City WWTF, including sludge
hydrolysis process alternatives, digestion upgrades, and dewatering process alternatives.
The evaluation also includes phosphorus and nitrogen management alternatives associated
with sidestreams from solids dewatering, including struvite harvesting technologies, ammonia
stripping, and sidestream nitrification or Anammox treatment. Conclusions from the
evaluations, based on life cycle cost comparisons documented in technical memoranda, will
be incorporated into a Biosolids and Biogas Master Plan for the City.
Wastewater Treatment Facility Upgrades, Marion, Indiana. Process Engineer: Evaluated
alternatives to address age-related deficiencies and improve wet -weather treatment
capacity at this 21-mgd wastewater treatment facility. This project was prompted by the
requirements of a Long -Term Control Plan (LTCP). This facility consists of two parallel
activated sludge treatment plants (North and South), solids thickening, and anaerobic
digestion. Capacity increasing alternatives included preliminary treatment enhancements,
raw wastewater pumping enhancements, primary treatment expansion, conventional
activated sludge system expansion, Bio Actiflo activated sludge, disinfection expansion
(gaseous chlorine, liquid chlorine, and UV), and flow equalization.
Biosolids Dewatering and Drying Improvements, Sheboygan, Wisconsin. Project
Principal: Project included the design of biosolids dewatering and drying facilities at the
56-mgd Sheboygan Regional Wastewater Treatment Plant. The project included preparing
owner procurement documents for the City to purchase major pieces of process equipment
and then preparing plans and specifications for a contractor to install the procured
equipment and other support facilities. The project added screw press dewatering
equipment, cake sludge pumping, a medium temperature belt dryer, biosolids cooling and
transport equipment, and a biosolids storage silo with a nitrogen blanket for fire
suppression. Nitrogen is generated onsite using a rotary screw compressor and membrane
separation system.
Solids Handling Upgrade, Gary, Indiana. Quality Control Reviewer: Donohue designed a
solids handling upgrade for the Gary Sanitary District's 30-mgd wastewater treatment
facility. The upgrade included three gravity belt thickeners, four belt filter presses, polymer
systems, three gravity belt feed pumps, and three belt filter press feed pumps.

JEREMY C. CRAMER
PROJECT EXPERIENCE
Mr. Cramer has 20 years of wastewater and water treatment experience. Throughout his
career, he has been involved in the management, operation, and maintenance of both
wastewater and water treatment facilities. Under his guidance, two different wastewater
facilities have been recognized for operation and performance and have won Utility of the
Future Awards from WEF. He has also overseen the operation and maintenance of sanitary
lift stations, stormwater lift stations, and water wells. Mr. Cramer has had a tremendous
amount of experience in the area of wastewater treatment with a focus area in anaerobic
digestion, biological nutrient removal, and energy efficient operations.
Biosolids Operations, Stevens Point, Wisconsin. Chief Operator/Wastewater
Superintendent: Mr. Cramer played a large role in keeping biosolids costs down. While at
the Stevens Point facility, he was able to reduce the combined polymer and hauling costs
by approximately $40,000.00 annually. The polymers cost savings were achieved by
modifying the dose point and keeping polymer dilution water at a consistent temperature
throughout the year along with keeping the digester feed temperature and total and
volatile solids consistent. Volume reduction of biosolids was achieved by developing a
creative way to decant supernatant off of liquid sludge storage tanks (not mixing the tanks
until needed and using a movable mechanism to get to clear decant layers). This volume
reduction allowed for substantial savings in hauling costs. Mr. Cramer was also able to work
with several area farmers and get hundreds of acres WI DNR approved for land
application and was able to set up a biosolids land application program that was careful
to not apply too much phosphorus on field sites.
Biosolids Operations, Fond du Lac Wastewater Treatment Facility, Fond du Lac,
Wisconsin. Wastewater Superintendent: Mr. Cramer was able to change the amount of
biosolids that were land applied verse land filled dramatically. Prior to Mr. Cramer's arrival
approximately 70 percent of the facility's biosolids were landfilled and the remaining 30
percent was land applied. During his tenure at the facility this was changed to 70 percent
land applied and 30 percent land filled which led to great cost savings for the Fond du Lac
facility. Mr. Cramer implemented a biosolids program that focused on biosolids being
beneficially reused.
Energy Efficient Operations, Fond du Lac Wastewater Treatment Facility, Fond du Lac,
Wisconsin. Wastewater Superintendent: Mr. Cramer was instrumental in operating this 8
mgd average daily flow facility as energy efficient as possible. Under Jeremy's direction
and operational changes at the Fond du Lac wastewater facility, several energy efficient
savings were realized. Several operational changes included moving the dissolved oxygen
set point down to 1.0 mg/L and lowering the pressure set point of the aeration system,
modifying the influent pumping scheme, taking basins and tanks out of service that were not
needed, maximizing biological nutrient removal, changing out lights to LED lights, installing
a UVT sensor to operate the UV system more efficiently and ensuring the CHP unit was
running continuously. The monthly electric bill was reduced by approximately $10,000 per
month. Natural gas usage and costs were also reduced at the Fond du Lac facility, a
reduction of approximately $60,000 per year was achieved by making better use of the
facilities extra biogas. Natural gas savings were realized by ensuring the CHP unit was
running and that the hot water was being used effectively and making gas piping
modifications to all the plant boilers to better utilize biogas. Mr. Cramer was instrumental
in the decision to pursue and implement a side stream ammonia removal process that would
not only reduce energy consumption at the facility but would also save carbon to drive both
denitrification and biological phosphorus removal.
High Strength Waste/Substrate Acceptance Programs, Stevens Point, Wisconsin. Chief
Operator/Wastewater Superintendent: While in Stevens Point, Mr. Cramer developed a

Water Pollution Control Plant Upgrades, Fort Wayne, Indiana. Lead Structural Engineer:
Design of primary clarifier and other plant upgrades at the Fort Wayne Water Pollution
Control Plant (WPCP), including preparation of plans and specifications. This project was
Phase 2 of a proposed 7 -phase upgrade plan. The Phase 2 project consisted of four new
146 -foot diameter primary clarifiers, a below -grade primary sludge and scum pump room
connected to the existing plant by tunnels, a new limestone -faced Primary Clarifier Control
Building, a new limestone -faced Phosphorus Removal Facility, conversion of the existing
Chlorine Building to a Hypochlorite Storage Building, demolition of the existing primary
clarifiers, extension of the primary effluent conduit to the existing aeration basins,
modifications to the aeration basin influent system that included a redundant alternate
distribution system, modification to the existing administration building, and modification to
the existing secondary clarifier complex. The new structures are pile -supported due to soft
soils at the site.
Wastewater Treatment Plant Upgrades, Eau Claire, Wisconsin. Project Manager/Lead
Structural Engineer: The project consisted of a major upgrade to the Otter Creek Lift Station,
a new sludge storage tank, and an effluent pH control system at the wastewater treatment
plant. As part of the Otter Creek Lift Station improvements, a transient analysis was done
on the existing 10,000 -foot long dual 24 -inch force mains. The results of the analysis show
how the use of surge relief valves in the pump station and vacuum relief valves along the
force main route affected the surge pressures that develop in the force main under power
failure and normal operation and how the additions to, or modification of, the existing
system would reduce the water hammer effects and pump header movement experienced
at the lift station.
Mississippi River Wastewater Treatment Plant Improvements, St. Charles, Missouri.
Lead Structural Engineer: The project consisted of a new raw wastewater screening building,
modifications to existing grit handling facilities, conversion of existing primary clarifiers to
aerobic selectors, expansion of the blower building, a new 133 -foot diameter secondary
clarifier, a new W3 water system, a new final effluent pump station, modifications to the
existing sludge dewatering building, a new sludge storage tank, a new sludge thickening
building, a new 80 -foot by 230 -foot sludge storage building, and a new storage garage.
Most of the new structures are pile -supported due to soft soils at the site.
Wastewater Treatment System Improvements, Lincoln, Illinois. Lead Structural Engineer:
The project consisted of new preliminary treatment facilities to house grit removal, screening,
and raw water pumping; a new stormwater intake structure; modifications to primary
clarifiers; new scum pump stations; modifications to aeration basins; new aeration basins;
new circular secondary clarifier; new RAS pump station; modifications to digesters;
modifications to sludge storage building; modifications to sludge drying beds including
adding pre-engineered metal building cover; new sludge dewatering building to house belt
press and chemical storage; modifications to service building; and new pre-engineered
wood truck storage building. The challenge of this project was to fit the new facilities within
a highly congested site and modify the existing facilities while keeping the plant in
operation.
Water Pollution Control Plant Improvements, Fort Wayne, Indiana. Lead Structural
Engineer: Design of Preliminary and Secondary Treatment Facilities improvements at the
Fort Wayne Water Pollution Control Plant, including preparation of plans and
specifications. This project was Phase 1 of a proposed 7 -phase upgrade plan. The Phase 1
project consisted of new preliminary treatment facilities, new septage receiving facilities,
modifications to the influent interceptor sewers, modifications to the secondary treatment
facilities, and new flood control facilities. The preliminary treatment facilities included fine
screening in three 5 -foot wide by 40 -foot deep influent channels, a four -pump 60-mgd raw
wastewater pump station (expandable to a six -pump 100-mgd pump station), two vortex
grit removal basins, and grit handling equipment.
