AGENDA ITEM: Wastewater and TMDL Compliance Program -Final Design
RFP 07-04
SUBMITTED BY: Donna Kaluzniak, Utility Director
DATE: March 13, 2009
BACKGROUND: The Department of Environmental Protection has created more stringent
requirements for the City's wastewater treatment plants due to the Total Maximum Daily Load
(TMDL) for nitrogen limits.
On September 10, 2007, the Commission awarded amulti-year contract with HDR Engineering Inc.
to complete engineering work needed to meet the TMDL requirements. HDR Engineering was the top
ranked firm with the strongest team based on depth of experience and variety of similar past projects.
This firm also had an excellent and well thought out project approach section.
HDR completed the preliminary design work and gave a presentation to the City Commission on
December 15, 2008. The most cost-effective way to meet the TMDL requirements includes
• Upgrading the existing Wastewater Treatment Plant #1 (1100 Sandpiper Lane) to meet
advanced treatment standards for nitrogen removal
• Constructing a force main and flow-shedding of existing lift stations to transfer flow from
Wastewater Treatment Plant #2 (739 Renault) to Wastewater Treatment Plant #1 and
• Properly abandoning Wastewater Treatment Plant #2.
The City Commission directed staff to negotiate a contract for final design of the recommended
improvements. Staff has been working with the engineer, and has negotiated the final design contract
in two sections:
• Force main, flow shedding and abandonment of Wastewater Plant #2 for a total of $388,433
• Upgrading the existing Wastewater Treatment Plant #1 to meet advanced treatment standards
for nitrogen in the amount of $678,719.
The total cost for Final Design for the Wastewater and TMDL Compliance Program is $1,067,152.
Included in the cost is evaluation of auxiliary generator power, odor control, and third-party value
engineering.
BUDGET: Funds in the amount of $1,100,000 are available in the Public Utilities Fund for the Final
Design for Wastewater and TMDL Compliance.

Gordon Grimes and John Collins. This project will focus on the project
goals, schedule, deliverables, facility maintenance issues and key contact
personnel.
2. Prepare for and conduct up to seven monthly status progress meetings.
Prepare meeting agendas for topics to be discussed. Review and comment
on meeting minutes. Monthly progress meetings will be coordinated with
percent level reviews in order to minimize meetings.
3. Prepare for and conduct up to three miscellaneous meetings pertaining to
the project. Prepare meeting agendas for topics to be discussed. Review
and comment on meeting minutes.
4. Prepare for and participate in a third party review of the forcemain and lift
station modification design. No review is expected for the decommission
of the Buccaneer WWTP.
5. Prepare for and conduct a presentation for the City Commission.
2.2 Pipeline and Pump Station Improvements to Transfer Flow to COAB # 1.
1. Based on the TMDL report that described various force main alternative
routes, the report deemed that three (3) routes were comparatively priced,
HDR will conduct up to two meetings with COAB and up to two meetings
with other stakeholders involved to establish the preferred route and any
needed easement acquisition. We may need HDR to meet with as many as
two (sets of) private property owners to discuss possible impacts of project
on them
2. Calculate the 20-year life cycle costs including capital and power costs for
pumping 100% of the Buccaneer WWTP flow versus the flow shedding
option presented in the TMDL Document. A spreadsheet analysis and
conclusions will be prepared on the analysis and presented to the OWNER
for acceptance
3. Design a maximum 12,800 linear feet of force main based on selected
route and flow to be transferred to COAB # 1. The design will incorporate
open cut, pipe bursting and/or horizontal directional drilling construction
measures where appropriate.
4. Design new pumping system upgrades needed to transfer flow from
Buccaneer WWTP to WWTP #1. The existing pump station and wetwell
at Buccaneer will be utilized and are sufficiently sized to install up to 3
pumps. The design of the pumping equipment will be based on
submersible pumps. The pump station will include new controls and
control panel in NEMA 4X - 316 stainless steel externally mounted
enclosure on a concrete housekeeping pad.
5. Evaluate the existing Buccaneer electrical feed for adequate size and make
recommendations if improvements are needed. If the existing electrical
system is undersized, HDR will assist the OWNER with coordination with
the power supplier. Any additional design for the electrical services is
considered additional service.

AGENDA ITEM # 8B
MARCH 23, 2009
6. The HDR initially assumes that the existing Buccaneer emergency
generator, fuel system and automatic transfer switch have sufficient
capacity for the master pump station improvements and can be utilized for
standby power. HDR will verify this assumption during preliminary
design and make any recommendations required to upgrade this system if
needed. Specific emergency power and fuel system design is excluded
from the scope of services. However, the emergency generator, fuel tank
and control/transfer switch panel will be relocated as a part of the design
in order to make lift station site more compact..
7. Prepare Construction Project Manual. HDR will utilize HDR front-end
documents and technical specifications. HDR anticipates two construction
contracts with separate bids for this project. One project will include the
pump stations and pipelines. The second project will include the
decommissioning of the Buccaneer WWTP. Modifications to this
assumption will result in additional services to change the construction
project manual and contract documents.
2.3 WWTP # 1 Master Lift Station Improvements. It is assumed that the existing
pumping and control system is adequate for 3.0 MGD -AADF plant flow,
however, additional wetwell capacity is anticipated to be required. HDR will
design a new wetwell based on future peak hour flows of approximately 7,900
gpm or 5.0 MGD -AADF. HDR will verify the existing pumping capacity versus
the proposed pumping capacity. Up to two site visits will be provided for the
purpose of detailing the existing LS pump vault and piping dimensions and
inventory existing LS power demands and generator. The design will include
verification of existing system hydraulics to the screens at the head works,
proposed hydraulics with recommendations for lift station improvements as well
as the civil, structural, electrical, and instrumentation and control system design.
2.4 Shed flow from Buccaneer collection system to WWTP # 1 system: As
defined in the TMDL Document, one aspect of decommissioning the Buccaneer
WWTP was to flow shed a portion of the Buccaneer collection system flow directly
to WWTP #1. HDR will perform the following services as part of this task:
1. The route proposed in the TMDL Compliance report was to utilize a
portion of the existing force main system (8" FM) along Mayport Road
between Assisi Lane and Lewis Street. The existing force main will be
extended with new 8" PVC pipe to the existing wet well of the Master
Lift Station at WWTP#1. The work will include designing a maximum of
3,7001inear feet of new force main and may incorporate any combination
of open cut, jack and bore or horizontal directional drilling construction
measures where appropriate.
2. Determine with COAB and other stakeholders what new connections, if
any, that may be needed along the new force main.
3. Perform a spreadsheet evaluation of the system hydraulics for up to 10
existing lift stations with flow to be diverted to COAB # 1 and identify
potential pump modifications. The HDR will provide a list of pump

improvements identified. It is assumed that the existing pump station
structures and wetwells are adequate in terms of size and structural
integrity. No condition assessment activities are required or included in
this scope. The modifications required will be considered as maintenance
activities and no permitting will be required. No drawings will be provided
for the work effort. It is assumed that all pumps are self-priming Gorman
Rupp pumps and the power requirements remain the same as currently
exist for each pump station. No additional electrical design or evaluation
is required or included in this scope of services.
2.5 Decommission and Demolition of Buccaneer WWTP: As the upgraded Master
Lift Station at Buccaneer WWTP is completed and placed into operation, the
Buccaneer WWTP can be decommissioned and demolished. The Buccaneer
facility will be completely out of service when this activity is performed. This
project will be advertised as a separate project and will follow the forcemain/Lift
station improvement projects. The associated activities for the decommissioning
and demolition are as follows:
1. Conduct one meeting with FDEP to discuss the requirements for
decommissioning and demolition of the Buccaneer WWTP.

ATTACHMENT NO. 1
SCOPE OF WORK
ODOR CONTROL AND AUXILIARY POWER AND FUEL EVALUATIONS
A. Odor Control Evaluation
As part of the 30% Preliminary Engineering Report, JCEA will collect, organize,
interpret and summarize information to develop an understanding of the odor control
needs at the COAB WWTP No. 1. In order to identify the potential odor causing
compounds at the plant, both liquid and gas phase sampling is recommended.
Based on the location of WWTP No. 1, the close proximity of adjacent residential homes,
and the potential redevelopment of the Royal Palms community, a more detailed
sampling approach is recommended as opposed to vendor provided sampling for
hydrogen sulfide gas. This level of sampling will provide the OWNER with the data to
develop an odor control strategy that will address the full range of potential odor causing
compounds. Activities to be performed include the following:
Schedule and conduct one site reconnaissance visit to visually assess WWTP No.
1. Previous discussion with COAB suggests that the odors sources include the
existing headwork's influent structure, solid handling, and secondary clarifiers.
The COAB shall attend and provide operational input on known or suspected odor
sources, plant processes, and provide input for other questions from JCEA.
2. Develop an odor control-sampling plan. It is assumed that COAB staff will
conduct the sampling within atwo-week period after the site reconnaissance visit.
The sampling will consist of the following:
Over atwo-day period, at approximately 9:00 am and 3:00 pm each day, OWNER
crewmembers will obtain grab samples for the following gas phase wastewater
parameters at WWTP No. 1 at the locations identified in the sampling plan:
a. Hydrogen sulfide -two (2) samples during each sampling event, eight (8)
total samples
b. Amines -two (2) samples during each sampling event, eight (8) total
samples
c. Mercaptans -two (2) samples during each sampling event, eight (8) total
samples
d. Ammonia -two (2) samples during each sampling event, eight (8) total
samples
Sampling should be performed during any expected odorous periods. JCEA assumes
that the OWNER will perform the sampling and that JCEA or other team members
will require no field services.

AGENDA ITEM # 86
MARCH 23, 2009
3. Upon completion of the sampling, JCEA will evaluate and prepare a
recommendation for odor control improvements, which will be summarized in the
Preliminary Engineering Report. The recommendation will include one site plan
schematic showing the location of the odor control equipment with respect to unit
operations, narrative of the equipment components and requirements, and a
budgetary cost for construction including associated engineering costs. The data
and product information will be included as an appendix within the Preliminary
Engineering Report. Up to two gas phase odor control systems will be considered
for the evaluation.
4. In order to effectively complete the evaluation and minimize engineering costs,
JCEA will base the evaluation upon the Siemens line of odor control equipment
which has numerous examples of proven and cost effective odor control systems
within the Florida, the United States, and Internationally. Should the OWNER
elect to proceed with the design, preparation of construction bidding documents
for the odor control system, the Siemens system will not be a sole source item,
and JCEA will provide documents, which allow for a competitive bid. During the
ensuing design, JCEA will coordinate with other vendors as well to confirm
product suitability and budgetary quotes from prospective vendors. This
evaluation is intended to provide the OWNER with an odor control solution for
WWTP No. 1 and is not intended to serve as an evaluation of the available odor
control systems in the market.
B. Auxiliary Power and Fuel System Evaluation
As part of the 30% PER, JCEA will perform an evaluation on the existing auxiliary
power and fuel systems at the COAB WWTP No. 1. The purpose of the evaluation is to
confirm whether the existing auxiliary power and fuel systems are adequate for use at
WWTP No. 1 for the proposed plant expansion and to investigate the possibility of
combining the three power sources and three generators into one power source and
generator. The evaluation will consider the following:
1. Review and evaluation of existing auxiliary power and fuel systems with respect
to existing electrical loads and the proposed electrical loads associated with the
plant expansion. The combined electrical load calculations will be used to
confirm whether the existing generators can be used as permanent generators for
the plant expansion. The age and condition of the existing generators will also be
considered in recommending to either replace or refurbish. The evaluation will
also investigate the requirements and siting options for new auxiliary power and
fuel system and one supply source. The new system will consist of one single
generator with automatic transfer switch, above ground double walled fuel tank
and piping, one day tank, and automated leak detection and alarm system.
2. Prior to initiating the evaluation, JCEA will schedule and facilitate a kickoff
meeting at the plant with designated WWTP No. 1 operations staff. The purpose
of the meeting is to assess the information available for the study. JCEA

representatives will tour the plant and interview plant operations and maintenance
staff with respect to emergency power operations to identify where problems may
exist in the existing emergency power system. JCEA will prepare meeting
minutes and will present to the County a list of additional information required for
the study.
3. JCEA will analyze the existing conditions at the WWTP No. 1 based on available
information provided by COAB. The analysis will include a cost comparison
made between the existing electrical and generator system as it is now operated
versus the cost of the new system. Capital and operation and maintenance costs
and the meter demand charges will be considered. It will also include a review
and summary of information from the following existing documentation.
a. As-Builts drawings of the Plant
b. O&M Manuals for process equipment and operating protocol for generator
use.
c. Electrical Utility bills showing meter demand charges and O&M costs for
the operation of the existing system for the previousl2-month period.
d. Electrical load list identifying the use, motor Hp, KVA, Power factor,
amps, voltage, motor frame, RPMs, status of the load during an
emergency, GPM or ACFM pump rate, location in the plant and power
source location that is being serviced by each generator
e. Generator list showing manufacture, Kw size, RPM, and transfer switch
manufacture, size and fuel storage capacity at WWTP No 1 and the
Buccaneer WWTP.
4. JCEA will review the power service feeds at the site and provide
recommendations on any modifications that may be beneficial for the plant
expansion.
5. JCEA will use the U.S. Environmental Protection Agency Bulletin 430-99-74-001
titled "Design Criteria for Mechanical, Electric and Fluid System and Component
Reliability" as a guidance document for the evaluation.
6. As part of the PER, JCEA will summarize the requirements and costs for
emergency generation systems, and will provide a schematic level electrical one
line diagram reflecting the use of the recommended auxiliary power and fuel
system and associated design criteria to be implemented at WWTP No. 1.
