SCOPE OF WORK
SEWER SYSTEM MANAGEMENT PLAN UPDATE
The following Scope of Work amends Attachment "A" of the August 28, 2007 Agreement for
Professional Services Contract between the City of Ukiah and Winzler & Kelly (hereinafter
referred to as "SSMP Contract"). The Scope of Work generally includes flow monitoring and
hydraulic modeling to augment Element 8 of the City's current SSMP.
Task 7 of the SSMP Contract (System Evaluation and Capacity Assessment Plan) is augmented
by the Scope of Work. Tasks 8 and 15 ("Capital Improvement Plan" and "Financial Plan",
respectively) are hereby removed from the SSMP Contract and should be completed under a
separate contract following completion of the Scope of Work.
Task No. 1- Project Management
1.1 Coordinate efforts of the project team and sub-consultants, monitor project schedule and
budget, and administer the Professional Service Agreement with the City.
1.2 A work plan will be prepared setting forth significant milestones and deliverables for
team members to ensure compliance with the established project execution strategy and
project goals. Revise the work plan following the "kickoff' meeting discussed below.
1.3 At the commencement of the Project, the Consultant will conduct a "kickoff' meeting
with City project staff at the City offices located at 300 Seminary Ave, Ukiah, to discuss
the following:
a. Introduction of Project Team for both Consultant and City.
b. Project scope, parameters, and schedule.
c. Identify specific tasks, goals, and milestones to be accomplished and discuss or
develop effective strategies to accomplish the project goals.
d. Review available documents.
1.4 Arrange for and meet with other City Departments and agencies in order to collect
information for the completion of the project. The City project team will participate in the
meetings on an as needed basis.
1.5 Prepare monthly progress reports summarizing the actual work performed, meetings
attended, unresolved project issues, and the status of each task's schedule and budget.
Progress reports will be submitted with monthly invoices.
1.6 Arrange for and participate in informal project meetings, conference calls, or e-mail
communications with the City project team members to review progress and to exchange
ideas and information. An allowance of a minimum of one meeting per every other
month is to be included in the project budget. However, the Consultant will be expected
to conduct as many meetings, conference calls, or participate in e-mail communications
to ensure that the needed exchange of information and ideas takes place in timely
manner.
1.7 Arrange for and participate in up to three (3) City Council meetings to facilitate public
involvement with the flow monitoring and modeling efforts.
Task No. 2 - System Evaluation and Capacity Assurance Plan (SECAP) Update
2.1 Evaluation of the sanitary sewer system including:
Flow monitoring
The purpose of the work is to develop flow generation rates for different sewerage basins.
Flow rates could be based on analysis of current land uses, infiltration/inflow (I/I)
evaluation, review of existing reports, and percent of metered water that is discharged to
the sewer system under different conditions.
Flow monitoring includes eight (8) flow meters installed for a duration of ten (10) weeks
during which time the flow meters will be periodically monitored and calibrated. Upon
coordination with the flow monitoring crew, the location of up to two (2) meters could be
relocated during the flow monitoring period. Collected flow monitoring data should be
evaluated near the completion of the 10-week period to assess the data's viability for
hydraulic modeling purposes. Flow monitoring beyond the 10-week period is not
included in this scope of work, but may be recommended based on evaluation of the
collected data.
Hydraulic Model
This scope includes the development of a hydraulic model for approximately 25 percent
of the existing collection system. This percentage generally represents trunk lines with
diameters equal to and greater than 10 inches. Some smaller diameter pipes may also be
modeled upon further evaluation of the collection system. Since the hydraulic model will
be built based on available record drawings, it may not be feasible to model portions of
the sewer collection system.
The hydraulic model will be MWH Soft H20Map, most current edition.
Features of the model will include the following inputs and results:
The model will incorporate necessary information into the hydraulic model including,
but not limited to: current City and County land use designations, existing sanitary
sewer system characteristics, sewer lift stations, calculated inflow and infiltration
flows, existing population data, and existing water usage data. Some augmentation of
existing record information may be necessary to model portions of the sewer
collection system. Field survey of the sewer collection system is not included in this
Scope of Work.
Development of synthetic hydrographs for each flow monitoring location for a 10-
year design storm.
2
0 Calibration to simulate the actual physical system under existing conditions.
® Determination of hydraulic capacity of modeled existing system components.
® Identification of existing hydraulic deficiencies and the sources that contribute to
peak flows.
2.2 Review Draft Sanitary Sewer Hydraulic Design Criteria included in the SSMP, including:
Applicable items as necessary to ensure adequate hydraulic capacity for dry weather
peak flow conditions and peak wet weather flows from an appropriate wet weather
event.
Average flow rate, peak flow rate, main line sizing, velocities, grades, depth of cover,
and other appropriate criteria.
2.3 Prepare Summary Report Including Hydraulic Capacity Enhancement Plan. Consultant
will submit three (3) hard copies and one electronic copy of the draft and final Summary
Report for review by the City.
® Identification of existing pipelines determined to be hydraulically-deficient.
® Analysis of remediation alternatives considering costs and associated benefits.
® Prioritization of deficiencies to be addressed.
2.4 Update System Evaluation and Capacity Assurance Plan Element in SSMP (Element 8).
Consultant will submit three (3) hard copies and one electronic copy of the draft and final
Summary Report for review by the City.
® Revise Element 8 of the current SSMP per the results of the flow monitoring and
hydraulic modeling of the existing collection system. Following the update to
Element 8, the City and District would update the State's online database for the SSO
program (CIWQS).
Services Not Included
® Analysis of future flows derived from General Plan growth. However, this analysis
should be completed during master planning wherein land use, population, and other
general plan projections would be considered.
Work covered under Tasks 8 and 15 of the SSMP Contract dated August 28, 2007.
Review and analysis of-CCTV records. However, condition assessment of the sewer
collection system should be completed during the master planning project.
Field survey of the sewer collection system. It is anticipated that additional field data
would enhance the accuracy of the hydraulic model, as the model would be primarily
based on record drawings. The collection of rim and invert elevations for key points
in the sewer collection system could be performed by City forces.
® CEQA documentation. The. City will need to provide documentation during the
master planning project for the connection between the master plan and build-out
assumptions in the City's current General Plan.
