CITY OF LODI,
FOR
SEWER MASTER'PLAN
Y -
PURPOSE
The rima ose for the preparation of this sewer master" plan is
P rY PurP P P P
to. provide for the orderly addition to the existing wastewater collection
� .
aad transport system to provide adequate service.for existing and,future
populations within the City of Lodi planning area. The.secondary purposes
areto provide engineering `support _regarding the. collection
_.
system to the EIR consultant for the Moratorium Study Area and to 'evaluate
;
the physical condition of the collection system in the Eastside Sewer Study
Area.
F
SCOPE OF WORK .
t
To execute the purpose of this study, the following scope of work will
be :completed.
i
Task 100,— Sewer Master Plan
To prepare an overall Sewer; Master Plan `or the City of Lodi .seryiceq:
area, the following specific'tasks will be undertaken.
>101 Using_the existing and future population �land and zoning
_use,
3
provided by the City,'develop unit wastewater contribution by use
,
`,.
type that reflects the actual measured flow at the White Slough
T
j.
wastewater- treatment facility. ,Also develop,minimum, peak, and
}
wet wyather flow= ratios and -project future system flows
�.
102 Develop a hydraulic model:of the existing collection system using
i
the Black :&.Veatch "SEWER" program 'The model will include the
`
i;
basic main and submain;'system but '.not.'collection'sewers. J' The .l
=
network will be reviewed and approved by the City.
_
103
Run the model to calibrate it with plant influent records.
;$
Perform subarea calibrations for flow data at nine ,key locations
in the City. Flowmeters will be provided by Black &.,Veatch but
A
installed and removed by city staff under the direction of the
engineer. _
104
,Develop standard sewer system design criteria to guide city staff
g{
in the review 'of development plans.
105
Using future .flows, run the "SEWER" model to identify system
deficiencies as the .City grows. Also, summarize the overall
.
i
conditions of .the existing syste<as based upon interview with City
..
staff.
106
Develop recommendations for system improvements including size,
routing,and cost to accommodate future growth. Plans shall be
based upon design standards and natural contours as defined by
14
_
USGS_mapping. ,.
107
For three large undeveloped areas identified by city staff,
develop specific recommendations for providing collection sewers._
108
Develop a recommended sewer maintenance plan.
109
.Provide a:draft'report for. City review.
110
Incorporate City comments into a final draft for City review..
Ill
Incorporate, City comments regarding the final draft and prepare
'the, final report for printing.'.: 'lave" the number of final' copies•
`
required,,by the City printed and delivered. Actual printing will
be`billed.separately.
I12
A user program manual, data files, and user subroutine will be
a
developed and'provided.the City, to, allow city staff :to run'the.
SEWER" model_by telephone"modum access to the Black & Veatch
,.
computer.
'
113
Provide the City staff- with training, hardware computer analysis,
and start—up assistance to get the model operational from City
i
offices.
-`
114
Provide �'four,;review meetings with city, staff as follows:-
a.`'' Interviews with maintenance personnel.
b. ' Review of flow :projections',design standards, and analysis
of existing system.

d. Review of final report.
Task 200
- Apartment Moratorium Study Area
F-;
To
provide engineering support to the City's EIR consultant for the
Apartment
Moratorium Study Area, the following specific tasks will be
undertaken.
201

Study Assumptions'.
mak.
This scope of work is based upon the following assumptions:
o Work will;be concurrent with the EIR water system and traffic_-
s
consultants for.the Apartment Moratorium Study.
o Population, growth, land use,, and zoning to be incorporated into,
n
the :master. plan Will be prepared: by. others.
o Existing sewer. maps are up-to-date and accurate. Any required
field verifications will be performed by the City.
P48m4 -4-
x
s
o The industrial collection system will not be addressed in the
�r
study.
o Work will not include detailed inspection/evaluation of each pump
`
i
station.'
'
o Final report printing will be paid by the City at cost.
SCHEDULE
Tasks 101, 102, 103, 104, and 108 can be completed in 8 weeks of
notice to proceed. The schedule then becomes dependent upon the EIR
consultant and the completion of Task 200. Once Task 200 is completed, a
draft sewer master plan can be completed in an additional 6 weeks. Without
the delay for Task 200, a draft of the sewer master pian would be complete
u is
in 16 weeks.
