Statement of Understanding
of the Project
The goal of theWastewater and Sewage Facilities Master Plan Update (WSFMP) is to update the recommendations of the
previous master plan and to provide an updated and prioritized CIP. THE CITY OF BARSTOW // CITYWIDE WASTEWATER AND SEWAGE FACILITIES MASTER PLAN CAROLLO // PROPOSAL // APRIL 2022
\\Io-bd-1\bd-data\Marketing\Pursuits\Client20(OCO)\Barstow\CitywideWW,Water&SewerFacilitiesMP\Prop0422\Indd\2-Statement of Understanding of the Project 1 STATEMENT OF UNDERSTANDING OF THE PROJECT
The City has requested proposals to update
your previous wastewater master plan.The
City has a strong growth potential, and has
received numerous development inquires in
recent years. The goal of theWSFMP is to
update the recommendations of the previous
master plan to include revised growth
assumptions within the planning area, and
to provide an updated and prioritized CIP to
provide reliable, cost-effective services for
existing and future customers.

In addition, the City would like to provide
integration with their hydraulic model and
geographic information systems (GIS), and
to conduct a planning level evaluation of the
wastewater treatment facilities, water reuse
potential, and funding options.

Development of thisWSFMP will require
addressing the following key challenges:
Coordination with the City’s planning
department and the development
community to develop realistic
growth assumptions.
Development of a prioritized CIP that is
flexible enough to accommodate future
changes in growth assumptions.

The challenge agencies encounter is how
to adapt their CIP to changes in growth
assumptions/timing. Change in the future is
a certainty, and that change will affect future
funding decisions.

Developing a master plan that provides the
ability to be nimble and respond to changes in
the timing and size of development projects is
key to project success. We will develop a new
CIP planning tool that is a complete summary
of your CIP projects. The projects are each detailed in separate worksheets, complete with a project summary, cost, and the growth triggers for the project. The project summary sheets are linked to an integrated CIP master summary table.

Our tool will update the timing of improvements/costs through a simple adjustment of the target completion date. All of these changes are seamlessly updated in the CIP summary table.

The City’s General Plan identifies likely areas for future development. A key to the success of this project is close consultation with the City’s planning department to understand the latest information on likely development patterns within the City.

Trigger plots will help “right size” your CIP
refining project definition and schedule to
adapt to changing conditions.

RELEVANT EXPERIENCE

CITYWIDE WASTEWATER MASTER PLAN UPDATE
City of Chino Hills, California
The Carollo team was selected to prepare and deliver a sustainable and affordable update to the City of Chino Hills’ (Chino Hills) Citywide Wastewater Master Plan that establishes baseline system condition and hydraulic capacity, as well as establishes CIP needs, and meets the City’s requirements for operational reliability and future growth. As part of this ongoing effort, Carollo developed a new wastewater model using Chino Hills’ latest GIS, developed a flow monitoring plan with detailed maps, installed 13 flow meters at key locations, calibrated the model to provide an accurate representation of the current system, and performed quality assurance and quality control (QA/QC) at key milestones.

The flow factors will be updated as part of this effort and will consider the ongoing water master plan so that planning assumptions align between reports. In addition, Carollo completed CCTV on 20 miles of pipeline and performed condition assessments of the City’s sewer system to develop a comprehensive understanding of system condition and propose a rehabilitation approach to increase the useful life of the current assets.

WATER, SEWER, AND WASTEWATER TREATMENT PLANT

MASTER PLANS
City of Lemoore, CA
In 2017, the City of Lemoore worked with Carollo to
prepare a combined water distribution, wastewater
collection, and wastewater treatment master plan.

The City had never completed a master plan for this
infrastructure. The water distribution system consists of 115 miles of active water pipelines, ranging from 1 to 18 inches in diameter; 10 active wells; 5 tanks; and 4 pump stations. The wastewater collection system includes 82 miles of active gravity sewer lines, ranging from 6 to 21 inches in diameter; 17 lift stations; and associated force mains. The WWTP has a capacity of 2 mgd and consists of four ponds.

Carollo constructed a hydraulic model of the City’s wastewater collection system, which was calibrated against temporary flow monitoring data collected as part of the project. The findings of the collection system analysis were used to develop a set of recommended pipeline and lift stations upgrades and a staged capital improvement program for the City’s collection system.

KING CITY WASTEWATER FACILITIES PLAN AND

COLLECTION SYSTEM MASTER PLAN
City of King City, CA
In 2016, to determine the overall impact on future sewer rate increases, the City of King City retained Carollo to complete an evaluation of its collection system and wastewater
treatment facilities. Faced with mounting maintenance
requirements for the domestic pond-based system, potential for future regulations, difficulty meeting existing treatment requirements, and the desire to produce recycled water, the City decided it was time to upgrade its existing system to a modern, tertiary treatment facility.

Carollo developed a collection system hydraulic model for the City’s collection system, which was calibrated to dry and wet weather flow monitoring data collected as part of the project. The Wastewater Facilities Plan and Collection System Master Plan resulted in a capital improvement program that was used as the basis for a rate study. The resulting rate increases will fund the first phase of treatment plant improvements and the various collection system improvements.

THE CITY OF BARSTOW // CITYWIDE WASTEWATER AND SEWAGE FACILITIES MASTER PLAN CAROLLO // PROPOSAL // APRIL 2022
\\Io-bd-1\bd-data\Marketing\Pursuits\Client20(OCO)\Barstow\CitywideWW,Water&SewerFacilitiesMP\Prop0422\Indd\5-Scope 8 SCOPE
Task 1 – Data Collection and Existing/Future
Service Area Characteristic Identification
Carollo will review available relevant reports and other data for use in this project, as well as other relevant information. We will develop a data collection table that will be presented at the project kickoff meeting and will update the data collection table as items are received.

We will also update the City on outstanding items
remaining for the project. Carollo will review all relevant planning documents related to land use (including
residential, commercial, and industrial/cannabis sector uses), growth projections, and planned developments.

Based on this review, the land use categories and
acreage will be updated and used to determine existing
and future wastewater flow projections. Carollo will
coordinate with City staff on major developments that
will be included in the WSMPU, including a project
meeting with the City’s planning department.
Assumptions: Future growth will be generally based
on the sphere of influence (SOI), however, the City
may identify specific growth areas outside the SOI
as appropriate.
Deliverables: Data collection list (PDF and Excel file format); maps and data related to existing and future
study area land use (native file format and PDF).

Task 2 – Identify Wastewater Flows and
Sewer System
As part of this task, Carollo will summarize historical average and peak wastewater flow rates, and will
develop wastewater flow projections in five year
increments through 2040. In addition, we will categorize the City’s collection system facilities as local, collector, trunk, or interceptor pipes, and will identify/describe major interceptor reaches.
Deliverables: Maps and data related to wastewater
flows and the sewer system (Excel format and PDF –
wastewater categories and reaches will be provided
in GIS format).

Task 3 – Flow Monitoring
As part of this task, the Carollo team will provide
temporary flow monitoring services for a period of
two weeks, including at least one holiday, at locations selected by Carollo and the City. Based on our initial
review of the City’s collection system mapping, we have assumed that 16 flow meters will be installed as part
of this task.
Assumptions: Assumes no fee permits and that
traffic control services (plans and field controls) are not necessary beyond basic Watch manual type
controls at low traffic sites that can be handled
directly by an ADS two person crew (no flagging,
lighted arrowboard, 18 cones, and six signs).
Deliverables: Flow monitoring maps (GIS and PDF);
electronic flow monitoring data (Excel); and a flow
monitoring report (PDF).

Task 4 – Hydraulic Model Development and
Interceptor Capacity Analysis
Carollo will update the City’s existing collection system hydraulic model, re-allocate wastewater flows into
the model, and re-calibrate the model based on the
