FROM: Dan St. John, F.ASCE — Director, Public Works and Utilities
Larry Zimmer, P.E. — Deputy Director, Public Works and Utilities
SUBJECT: Resolution Authorizing the City Manager to Execute a Professional Services
Agreement for Engineering Services for the Tertiary Process Upgrades at the Ellis
Creek Water Recycling Facility
RECOMMENDATION
It is recommended that the City Council adopt the attached Resolution Authorizing the City
Manager to Execute a Professional Services Agreement with Carollo Engineers for Engineering
and Design Services for the Tertiary Process Upgrades at the Ellis Creek Water Recycling
Facility.
BACKGROUND
Ellis Creek Water Recycling Facility ( ECWRF) has been in operation since early 2009 and
currently processes an average dry weather daily flow of 4.7 MGD (million gallons per day). The
plant, rated at 8 MGD overall, was designed to process up to 6.7 MGD of dry weather flow and
35 MGD during wet weather events when infiltration and inflow of stormwater to the wastewater
collection system is high. Overall, the plant has performed well and has consistently achieved
compliance with all requirements. To meet growing demands for reclaimed water, the plant's
tertiary filtration and reclaimed water disinfection processes requires upgrades. Since 2012, the
use of recycled water increased from zero to 22 million gallons per year for parks, schools and
open space. These demands are expected to grow as additional areas are added including the
recent addition of 10 holes at Rooster and Adobe Creek golf courses. The background of the
process to evaluate the upgrades was documented in the June 1, 2015 City Council staff report
(Attachment 4), in which the three improvement elements are discussed, including those for
solids digestion and processing and aeration of the activated sludge process. The June 1, 2015
staff report and City Council approval was for Element 1 — Solids Digestion and Processing
Upgrades.
The next step in the plan to upgrade ECWRF is to begin design on Element 2 - Tertiary
Treatment Upgrades. This element will add a second continuous backwash filter and install
ultraviolet (UV) equipment in the existing third channel. This will allow an increase to the
maximum summer -month reclaimed water deliveries to existing and future customers by
increasing through -put from the current daily maximum through -put of 4.3 MGD to 6.0 MGD.
This will allow the system to operate consistently within its average day design capacity and
reduce the number of days that the filters are currently operating near the maximum day design
capacity. Currently the filters operate near the maximum day design capacity for much of the
peak summer irrigation months. The maximum day demand on the tertiary system increased nine
fold in 2013 when the old secondary effluent system that supplied the legacy agricultural users
was moth balled and those demands were put on the tertiary system.
The City, in partnership with the North Bay Water Recycled Water Authority, submitted a State
Proposition 84 grant proposal that includes this project element, but was unsuccessful, Staff is
applying for Proposition 1 funding. Projects that are ready to proceed will be judged more
favorably and therefore, moving the element into the design phase should help in obtaining grant
funding.
DISCUSSION
In March 2013, the Public Works and Utilities Department solicited proposals for engineering
and design services for Ellis Creek Upgrades through a Request for Qualifications (RFQ). Seven
Statements of Qualifications (SOQ's) were received in April 2013 that addressed the firms'
wastewater treatment engineering expertise. The engineering services included in the RFQ were
very specialized and Petaluma firms do not have the expertise or the capacity to perform the
analysis and design. As a result of the initial RFQ process, the City hired one of the firms to
conduct the Headworks Design and Plant Assessment addressed earlier. A list of consultants
then was developed for the subject project, based on the previous SOQ proposal review. Three
consultants considered most qualified from the SOQ process were solicited for engineering and
design services through a Request for Proposal (RFP) on December 16, 2014. The three firms
were Brown and Caldwell, Kennedy- Jenks, and Carollo Engineers. Carollo Engineers was the
only firm to submit a proposal for the subject project.
Carollo Engineers has significant expertise in all areas of wastewater treatment facilities design,
permitting and operations. Their team has the expertise to address the City's needs, and is based
nearby in Walnut Creek. Previous clients include Napa Sanitation District, City of Santa Rosa,
City of South San Francisco, and City of San Mateo. Carollo Engineers have an intimate
knowledge of the ECWRF, having provided planning, design, and construction services for over
10 years in the development of the plant. Many of the Carollo team members, including the
proposed project manager, were involved in the original design of the facility. Carollo staff is
very familiar with current operations and maintenance staff, other local facilities, and the
regulators at the San Francisco Bay Water Quality Control Board. Furthermore, Carollo has
continued to provide support to the City since the plant was built, at times without requesting
compensation.
The services include final design and engineering services for the construction of a new, second
five cell continuous backwash filter system, addition of UV disinfection equipment for the third
channel of the existing UV system, two tertiary feed pumps to the existing filter feed pump
station, and addition of strainers to the pond pump station discharge. The tasks of the PSA
include background review, and conducting a basis of design workshop summarized in the
technical memorandum for $33,798. The final design is the largest task in the PSA for $321,814.
Bidding and engineering services during construction accounts for $141,074. Environmental,
support services, and project management complete the PSA at $79,424. The scope of work is
included in Attachment 2. Project and construction management services will be provided by
City staff. It is recommended that the Council award the subject PSA to Carollo Engineers based
on a not to exceed contract with a limit of $576,110.
With anticipated funding, the schedule for the tertiary process upgrades includes completing the
design and selecting a contractor by June 2016. The construction is estimated to take up to 9
months. The construction phase is scheduled to be completed by the middle of 2017.
The proposed action meets Council Goals: "Plan for and implement priority capital projects as
funding permits."

EXHIBIT A
ELLIS CREEK WATER RECYCLING FACILITY UPGRADE PROJECT
TERTIARY PROCESS UPGRADES
SCOPE OF WORK
CITY OF PETALUMA
AND
CAROLLO ENGINEERS, INC
(ENGINEER)
PROJECT UNDERSTANDING
The City of Petaluma (City) commissioned the new Ellis Creek Water Recycling Facility (WRF) in 2009.
Since the plant was put into operation, the City Public Works staff has recognized that several factors
have changed since the original plant design criterion was established. This includes:
• Higher than expected organics loading, that exceeds the liquid and solids process capacity.
• High strength waste (HSW) from local agricultural - related businesses might be more
economically treated locally at the WRF.
• The solids process equipment lacks redundancy, which makes the higher loadings more
problematic for plant operation and maintenance.
• The need for tertiary recycled water has increased due to the current drought and other factors,
such as serving agricultural users with tertiary treated water.
Based on these factors and limitations, the City has already undertaken assessments of the liquid and
solids processes at the WRF and envisioned three phases of improvements at the WRF. This scope
outlines the details of the Tertiary Process Upgrade project. Two additional phases will address solids
and high strength waste handling facilities upgrades and are addressed in a separate scope of work.
The Tertiary Process Upgrades project elements include:
1. Addition of a second 5 -cell continuous backwash filter system
2. Addition of UV disinfection equipment for the third channel of the existing UV system.
3. Addition of two tertiary feed pumps to the existing filter feed pump station.
4. Addition of filters or strainers to the pond pump station discharge to the filter inlet.
DETAILED PROJECT SCOPE
The following scope of services was prepared based on our understanding of the RFP, site visits, review
of available information, and discussions with City staff. It includes the scope of work for design through
bidding and Engineering Services During Construction. It is anticipated that Construction Management
will be provided by the City.
TASK 1— BACKGROUND REVIEW
The purpose of Task 1 will be to identify any additional information required for design, and any data
gaps. Additionally, this first task is critical to setting the design criteria and reliability /redundancy criteria
for the project and the facility.
A kickoff meeting will be conducted with City management, operations and maintenance, laboratory and
other key staff to review the scope of the design project, project elements, and obtain background

TO: Honorable Mayor and Members of the City Council through City Manager
FROM: Dan St. John, KASCE — Director, Public Works and Utilities
SUBJECT: Resolution Authorizing the City Manager to Execute a Professional Services
Agreement for Engineering Services for the Solids Process Upgrades at the Ellis
Creek Water Recycling Facility
RECOMMENDATION
It is recommended that the City Council adopt the attached Resolution Authorizing the City
Manager to Execute a Professional Services Agreement for Engineering Services for the Solids
Process Upgrades at the Ellis Creek Water Recycling Facility.
BACKGROUND
Ellis Creek Water Recycling Facility (ECWRF) has been in operation since early 2009 and
currently processes an average dry weather daily flow of 4.7 MGD (million gallons per day). The
plant, rated at 8 MGD overall, was designed to process up to 6.7 MGD of dry weather flow and
35 MGD during wet weather events when infiltration and inflow of stormwater to the wastewater
collection system is high. Overall, the plant has performed well and has consistently achieved
compliance with all requirements. More recently, the plant has experienced increases in organic
loading from industries experiencing a rebound with the economy and from recent development
projects. To meet these and other growing demands for reclaimed water, the plant is in need of
upgrades to three elements of its operation, namely: solids digestion and processing, tertiary
filtration and disinfection of reclaimed water, and aeration of the activated sludge process. In
addition, the City has the opportunity of promoting energy generation from bio- methane
produced in the solids processing system with upgrades to accommodate acceptance and
processing of high strength waste produced by local industry. This material is currently
disallowed and is being hauled to Oakland and other sites.
To better understand the wastewater treatment and reclaimed water needs of the community, the
City Council held a workshop on March 11, 2013, and has adopted in its goals: "Focus attention
on supporting food and beverage processing, manufacturing, and alternative energy business
clusters ". Subsequently, the Council approved the award of engineering services on July 15,
2014 to design the replacement of headwork screens that had proved ineffective in removing the
new generation of disposable wipes and other stringing materials. In addition, a review of the
plant was conducted to evaluate current loading trends and provide input to staff as to what
23
elements should be included in future plant upgrades. The review concluded that the plant does
at times operate above the "paper" design capacity for organic loading while remaining within
projected capacity for flow and suspended solids. The evaluation allowed staff to conclude that
the original plant is robust and designed conservatively because operations yield consistently
high water quality effluent that is discharged to the River or used for irrigation. On June 21,
2014, the Council awarded a procurement contract for the purchase of two new headworks
screens and on February 23, 2015, the contract to install the screens was awarded. That project
is currently in construction.
In April 2014, the City submitted a grant application for a California Energy Commission (CEC)
grant to modify the plant to allow generation of compressed natural gas (CNG) for use in the
transit and garbage fleet that was unsuccessful. The application process provided a thorough
investigation of the energy production potential of using high strength waste from industry to
boost bio- methane production and subsequent CNG use. It should be noted that the Council
approved modification of the Wastewater Capacity Fee Resolution on December 1, 2014, that
along with recent collection of other outstanding wastewater fees, has allowed the City to
generate nearly $5,000,000 to fund the upgrades addressed below.
Based on the investigations since the workshop, the following plant upgrades are recommended:
Element 1 - Solids Digestion and Processing Upgrades: Add second 550,000 gallon
anaerobic digester to mirror existing digester, two strainpress units to screen fine debris,
second gravity belt thickener, third thickened waste pump, and related piping, controls,
and heating equipment. The project will seek to enhance related systems including
replacement of the existing dewatered sludge conveyance system which has been
problematic, addition of a truck scale for biosolids hauling, and installation of a second
grit classifier for redundancy. The primary benefit will be to provide redundancy and
reliability to the operations since currently there is only one digester and one gravity belt
thickener. The second digester will provide a buffer to the current 15 day solids
detention time permit criteria where current operation hovers at 16 to 18 days and will
allow modification of activated sludge process to reduce oxygen demand and improve
aeration.
Element 2 — Tertiary Treatment Upgrades: Add second continuous backwash filter and
install ultraviolet (UV) equipment in existing thud channel. Will allow an increase to the
maximum summer -month reclaimed water deliveries to existing and future customers by
increasing through -put from the current daily maximum through -put of 4.3 MGD to 7.8
MGD and reduce the number of days that the filters are currently operating above their
average day design capacity but still below their maximum capacity. The maximum day
demand on the tertiary system increased nine fold in 2013 when the old secondary
effluent system that supplied the legacy agricultural users was converted to tertiary. The
City, in partnership with the North Bay Water Recycled Water Authority, has submitted a
State Proposition 84 grant proposal that includes this project element, and may apply for
Proposition 1 funding. Projects that are ready to proceed will be judged more favorably
and therefore, moving the element into the design phase should help in obtaining grant
funding.
24
Element 3 — Aeration Upgrades: The organic loading of the plant with commensurate
increases in revenues has resulted from the adoption of "business friendly" policies. As a
result, the plant needs to either lower the oxygen demand of the activated sludge process
or add more air, or both. At this time, the pre - engineering work is underway to determine
the best course of action. It is believed, however, that one of the benefits of Element 1 is
that it will modify the existing process to reduce oxygen demand; however, other options
are also being investigated.
Energy Element — CNG Production Upgrades: As mentioned above, the City submitted a
CEC grant to help modify the plant for CNG production in an effort to allow the plant to
receive high strength waste (HSW) from food and beer industry customers. The element
will modify the existing septage receiving station to receive HSW and food waste, add a
second biosolids screw press and building, and associated site piping. Once completed, a
CNG generation and dispensing facility would be added to convert the bio- methane to
CNG to fuel City vehicles.
The next step in the plan to upgrade ECWRF is to move Element 1 - Solids Digestion and
Processing Upgrades into design. Should the Council choose to proceed, the project will be ready
for construction approximately one year after final design, environmental review, permitting and
bidding is completed. An award of a second professional services contract for Element 2 —
Tertiary Treatment Upgrades' will be placed on a future Council agenda to move that project
into design to enhance the chances of grant funding. Element 3 — Aeration Upgrades' is still
under study and may not be ready to proceed to design until the full benefits of Element 1 can be
evaluated after start up. The Energy Element — CNG Production Upgrades' will be evaluated
from an enterprise standpoint to assure that the costs can be borne by the industrial users who
would primarily be benefiting from the upgrades, net any energy production benefit the City
accrues.
DISCUSSION
In March, 2013, the Public Works and Utilities Department solicited proposals for engineering
and design services for Ellis Creek Upgrades through a Request for Qualifications (RFQ). Seven
Statements of Qualifications (SOQ's) were received in April 2013 that addressed the firms'
wastewater treatment engineering expertise. The engineering services included in the RFQ are
very specialized and Petaluma firms do not have the expertise or the capacity to perform the
analysis and design. As a result of the initial RFQ process, the City hired one of the films to
conduct the Headworks Design and Plant Assessment addressed earlier. A list of consultants
was then developed for the subject project, based on the previous SOQ proposal review. Three
consultants considered most qualified from the SOQ process were solicited for engineering and
design services proposal through a Request for Proposal (RFP) on December 16, 2014. The
three firms were Brown and Caldwell, Kennedy- Jenks, and Carollo Engineers. Carollo
Engineers was the only firm to submit a proposal for the subject project.
Carollo Engineers has significant expertise in all areas of wastewater treatment facilities design,
permitting and operations. Their team has the expertise to address the City's needs, and is based
nearby in Walnut Creek. Previous clients include Napa Sanitation District, City of Santa Rosa,
City of South San Francisco, and City of San Mateo. Carollo Engineers have an intimate
knowledge of the ECWRF, having provided planning, design and construction services for over
25
10 years in the development of the plant. Many of the Carollo team members, including the
proposed project manager, were involved in the original design of the facility. Carollo staff is
very familiar with current operations and maintenance staff, other local facilities, and the
regulators at the San Francisco Bay Water Quality Control Board. Furthermore, Carollo has
continued to provide support to the City since the plant was built, at times without requesting
compensation.
The services include complete design and engineering services during construction for a new
anaerobic digester, gravity belt thickener, strain press, pumps, modifications to the existing
methane digester, heating and mixing equipment, upgrades to the sludge conveyance equipment,
and addition of a truck scale and redundant grit classifier. The tasks of the PSA include
background review, design assumptions, criteria workshops and summaries for $88,330. The
final design is the largest task in the PSA for $534,623. Bidding and engineering services during
construction account for $253,630. Environmental, support services, and project management
complete the PSA at $123,297. The scope of work is included in Attachment 2. Project and
construction management services will be provided by City staff. It is recommended that the
Council award the subject PSA to Carollo Engineers based on a not to exceed contract with a
limit of $999,880.
The schedule for the solids process upgrades includes completing the design and selecting a
contractor by April 2016. The construction is estimated to take up to 10 months. The
construction phase is scheduled to be completed by the beginning of 2017.
The proposed action meets Council Goals: "Plan for and implement priority capital projects as
funding permits ", and "Focus attention on supporting food and beverage processing,
manufacturing, and alternative energy business clusters."
