AGENDA TITLE: Adopt Resolution Authorizing City Managerto Execute Additional Professional
Services Task Order with West Yost Associates, of Davis, for White Slough Water
Pollution Control Facility Discharge Permit Compliance Activities ($198,000) and
Appropriating $250,000
MEETING DATE: June 3,2009
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt a resolution authorizing the City Managerto execute an
additional professional services task order with West Yost Associates,
of Davis, for White Slough Water Pollution Control Facility discharge
permit compliance activities in the amount of $198,000 and
appropriating $250,000.
BACKGROUND INFORMATION: White Slough WPCF is experiencing significant biosolids storage
capacity limitations during winter months and the potential loss of
future land application options during warm months due to permit
requirements. The proposed biosolids storage and dewatering
facilities will allow for removal of biosolids during periodswhen they cannot be land applied. Additional
operational goals include:
• Providing additional biosolids storage capacity; and
• Providing the capability to remove one biosolids storage lagoon from service and perform
maintenance while the plant remains in operation.
Constructing a biosolids dewatering and storage facility will assist the City of Lodi in meeting future
discharge permit requirements and provide additional biosolids handling capacities. The structure will
consist of an 8 -foot high platform with a steel canopy roof for the dewatering equipment and the chemical
feed equipment. The dewatering equipmentwill consist of two skid -mounted rotaryfan presses.
Appurtenant facilities will include piping, pumps, and covered storage bays for the dewatered sludge.
The estimated cost of construction is $3.5 million that will be paid from the bond proceeds for the
White Slough WPCF construction projects. The projectwill be constructed in early 2010.
The White Slough WPCF Master Plan developed priorto the 2003 Phase 1 Improvements project
anticipated that biosolids may become an issue during future permit applications and discussed the
dewatering facility.
Staff is requesting an additional task order to the existing MasterAgreement with West Yost Associates
be approved for professional services for the design work necessary for this facility to be constructed
(proposal attached). West Yost Associates has designed the Phase 1 through 3 construction projects
and is uniquely qualified to design the biosolids dewatering and storage facilities. This may be the final

SUBJECT: Proposal for Engineering Services —Biosolids Dewatering Facilities for
White Slough WPCF, Lodi, CA
Dear Charlie:
We appreciate this opportunity to provide a proposal for completing design work on the Biosolids
Dewatering and Storage Facilities, and we look forward to working with you on this important
project for the White Slough WPCF.
BACKGROUND
White Slough is experiencing significant capacity limitations in biosolids storage Lagoon No. 2.
The City of Lodi (City) has recently completed concrete lining of Storage Lagoon No. 1 and the
structural portion of a sludge pump station. In the near future, the City intends to complete the
mechanical and electrical equipping of the sludge pump station and construct a dewatering
facility and a dewatered biosolids storage facility.
West Yost Associates (WYA) completed a preliminary design effort for these facilities in
April, 2008. The resulting documents consisted of two technical memorandums and preliminary
plan and section drawings. The preliminary drawings are attached to this proposal. Technical
Memorandum No. 1 (April 16, 2008) presented an analysis of present and projected future
biosolids production rates for the Lodi plant. Technical Memorandum No. 2 (May 12,200 8) was
an examination of the cost of three alternative approaches to dewatering and dewatered solids
handling. The preliminary design also included initial sizing of the sludge pump, the lagoon
mixers, and the rotary fan press dewatering units.
PROJECT UNDERSTANDING
We understand that the City intends to complete construction of the sludge pump station, construct a
dewatering facility, and construct a biosolids storage facility which includes two months of biosolids
storage, as recommended in Technical Memorandum No. 2. The dewatering and storage facilities are
to be located west of the digester complex and south of the sludge storage lagoons, on land that was
used for the soil stockpile duiing Phase 3 construction. Dewatered and stored biosolids will either be
land applied using a custom spreading service, typically prior to planting in spring and fall, or
disposed of off-site by a contracted service provider.

SCOPE
WYA will provide engineering design for biosolids pumping, dewatering and storage facilities.
The design will include:
1. Detailed mechanical design and electrical design of the sludge pump station. We
expect the design to include the capability to start the sludge pump in a low -head,
recirculating mode in order to establish flow, and the capability to flush sludge piping
with recycled water. The design will also include recycled water piping to the
dewatering facility. Because the sludge pump will see a wide range of sludge
consistencies with varying solids concentrations, the pump will be equipped with a
variable -frequency drive;
2. Design of the dewatering facility. The dewatering facility will consist of an
approximately 5,000 -gallon temporary storage tank for pumped sludge; two rotary fan
press skids with integral sludge pumps, polymer injection and controls; and a screw
conveyor for transferring dewatered solids to the storage facility. We expect to design
the dewatering facility to allow for the selection of either Prime Solutions or Fournier
rotary presses, both of which were pilot tested at White Slough. We expect the facility
to be an open, steel -framed structure. The dewatering facility will also include a small
heated prefabricated building for polymer storage and dispensing;
3. Design of the biosolids storage and loading facility. The structure is expected to
consist of three approximately 50 -foot wide concrete bays of varying lengths. We
expect the roof structure to be a conventional steel structure, however, we will
examine the possibility of using a pre-engineered/pre-fabricated roof design as a cost-
saving measure; and
4. Grading and paving design for truck access to the biosolids storage facility. We expect
access to be from the south, via the road leading to the NCPA facility.
Task 1. Prepare 75 Percent Complete Design Submittal
We will prepare a 75 percent complete design submittal. The 75 percent complete design
submittal will include process & instrumentation diagrams, site plans, overall structural and
mechanical plans, and an updated estimate of probable construction cost. Six (6) sets of
documents will be submitted for review. This submittal is intended to allow City staff and other
members of the project team to review and comment on the design approach prior to completing
detailed design of each project component. WYA will perform a general quality assurance review
of all documents prior to submission. Task 1 includes the following:
1. Attend design kickoff and site inspection meeting, and attend up to two additional
meetings or site inspections;
2. Provide Civil, Structural, Mechanical and Electrical drawings and Process and
Instrumentation Diagrams (P&IDs) at the 75 percent complete design level; and
3. Provide drafts of Division 0 and Division 1 Technical Specifications.

Task 2. Prepare 100 Percent Complete Design Submittal
We will prepare a 100 percent complete design submittal for final review and comment by the City
and plant staff. The 100 percent complete design submittal will reflect all comments regarding the
75 percent complete submittal, and will be a complete biddable set. Final drawings will be
submitted on polyester film and in electronic (AutoCAD 2007) format. Final specifications will
be submitted on printer -ready letter size paper, and in electronic (Microsoft Word 2003) format.
Task 2 includes the following:
1. Revise 75 percent complete design documents to reflect City and WYA design team
review comments; and
2. Prepare Division 2 through Division 16 Technical Specifications.
Task 3. Cost Estimate
On completion of the design we will provide an opinion of the probable cost of construction.
Task 4. Project Management
This task consists of tracking progress, schedule, and budget; coordinating with subconsultants; and
ensuring that the City's expectations are met in all aspects of the project. WYA's internal project
management tools will be utilized to provide timely, detailed accounts of budget status to the project
manager. Project progress will be tracked by the project manager on a regular basis and compared to
the schedule and budget status to control costs and ensure timely delivery of services.
ASSUMPTIONS
Our proposal is based on the following assumptions:
• No environmental compliance is included.
• No city building department review or compliance is included.
• Design services during construction are not included.
