BOARD AGENDA ITEM 4a
TO: Board of Directors
FROM: Julie Ryan, Principal Engineer
MEETING DATE: August 2, 2018
ITEM – PROJECT NAME: Pump and Blower Efficiency Tests
REQUESTED BOARD ACTION: 1) Approve Proposal from Riventa for efficiency testing of 4
existing blowers at the Wastewater Treatment Plant for a total cost of $4,000; and, 2)
Approve Proposal from Riventa for efficiency testing of 30 existing pumps at 9 sewer
stations and 3 water stations for a total cost of $30,000.
DISCUSSION: In April 2018, staff invited Riventa to demonstrate their pump efficiency
testing service at the Luther Pass Pump Station. Historically, staff has tested the pump
efficiencies at this station on a quarterly basis, using a volumetric method (isolating and
drawing down the on-site storage tank). Riventa’s method is unique, in that it measures
the thermal increase in the temperature of the process water as it passes through a
pump as an indicator of the efficiency of the pump. The benefit of this method is that
neither a flow meter nor tank isolation is required to assess the pump efficiency, only
temperature gauges positioned near the pump inlet and outlet. The Riventa test was
performed free of charge, and the results were very close to the District’s historic
quarterly results. Based on the positive outcome of the demonstration, staff requested
that Riventa prepare a proposal to perform additional efficiency tests for the District.
The District’s Asset Management Program, which is currently in development, will
include a protocol for periodic testing of efficiency of its process equipment (in
particular, pumps and blowers). Pump and blower efficiency is not only important for
energy savings, but also as an indicator of equipment health. However, efficiency
testing can be a costly and time-consuming effort, and the District maintains nearly 200
individual pumps and blowers.
Staff has received two proposals from Riventa, with the following scopes of work:
1) Perform one-time efficiency tests on each of the four Wastewater Treatment
Plant (WWTP) blowers, to inform the ongoing WWTP Energy Audit ($4,000).
2) Perform one-time efficiency tests on 30 pumps at water and sewer field stations,
to inform pump station condition assessments and the development of the
District’s Asset Management Program ($30,000).

Originally, staff had intended to test only the 4 blowers and 25 sewer pumps. However,
after further discussion, staff has identified 3 water stations that it would also like to
include on this first round of testing. Beyond the WWTP blowers, the stations proposed
for testing, include the following:
Sewer
• Al Tahoe Sewer Pump Station (3 pumps)
• Tahoe Keys Pump Station (2 pumps)
• Bijou Pump Station (3 pumps)
• Johnson Pump Station (3 pumps)
• Upper Truckee Pump Station (3 pumps)
• Trout Creek Pump Station (2 pumps)
• Tallac Pump Station (2 pumps)
• Ski Run Pump Station (2 pumps)
• Bellevue Pump Station (2 pumps)
Water
• David Lane Booster Station (3 pumps)
• Keller Booster Station (2 pumps)
• Flagpole Booster Station (3 pumps)
The work will include an initial site visit to each station to assess the setup and identify
locations for the necessary ports for the temperature gauges. Then the consultant will
return to run the test after the setup is completed by District staff and will generate a
report for each pump. If this first round of testing is efficient, with good results and useful
data for future planning, then staff will consider incorporating periodic testing by an
outside consultant like Riventa into the Asset Management Program.
The blower and pump efficiency testing will be performed as Task Order No. 1 under a
new Master Services Agreement with Riventa, in an amount not to exceed $34,000.
SCHEDULE: As soon as possible
COSTS: $4,000.00 (ENERGY); $22,000 (AMPMPS); $8,000 (AMPMPW)

1 Introduction
Response to Julie Ryan, email 16th May 2018 with options STPUD would like to investigate, these
were;
Testing 4 blowers and advising on energy efficiency measures
Test 22 waste water pumps and advising on upgrade options
Test 8 clean water pumps and advising on upgrade options
Monitoring the efficiency of Luther Pass pumps and optimising the transmission line,
numerous pumps and a turbine on variable tariffs
2 Specification and costs
STPUD: Application
WWTP: Perform one‐time blower efficiency tests (3 utility fed, 1 diesel)
STPUD: Problem
The District has recently undergone a condition assessment on the existing 30‐yr old blowers, with
positive results, but no efficiency tests were performed. The existing blower system has very little
monitoring or control. The District is currently developing a work plan for a 12‐month Energy Audit
of the Blower System, to identify instrumentation and control improvements to increase energy
efficiency.
RIV: Proposal

_A Aeration Blowers
STPUD: Application
Sewer & Clean Pump Stations: Perform one‐time pump efficiency tests at critical and/or expensive
sewer lift stations (22 pumps) and clean water stations (8 pumps)
STPUD: Problem
The District currently has no formal program for routine pump efficiency monitoring at its sewer
pump stations and certain clean pumping stations, and many have no (or inaccurate)
instrumentation making routine monitoring difficult. Pump efficiency monitoring allows the District
to assess pump health and make better decisions for rebuilding or replacement. Since many District
3
assets are of similar age, performance monitoring can help the District prioritize O&M and Capital
Projects.

BOARD AGENDA ITEM 4b
TO: Board of Directors
FROM: Julie Ryan, Principal Engineer
MEETING DATE: August 2, 2018
ITEM – PROJECT NAME: Luther Pass Power and Control Project
REQUESTED BOARD ACTION: Approve Proposal from the consultants, GHD, for
engineering services in an amount not to exceed $26,000.
DISCUSSION: In May 2017, the Board authorized a Scope of Work for GHD to perform
an evaluation of power quality data collected through the District’s SCADA system in
an amount not to exceed $54,956. The purpose of this project is to inform a long-term
solution to power quality issues that continue to be experienced at the site.
Since May 2017, GHD has been working with the District to extract the needed data
from the District’s SCADA system and to analyze the data. However, in their analyses,
GHD began to see problems with the data provided by the District, i.e., gaps and
inaccuracies. GHD has worked successfully with staff over the last several months to
resolve the issues with the data. However, the budget for the original work has been
depleted. At staff’s request, GHD has provided a letter explaining the problems with
the data, and requesting an additional $26,000 beyond the remaining project budget
to complete the power quality evaluation (see attached).
Because of the importance of this station, the deleterious effect that poor power quality
can have on the health of the station, and the ongoing cost associated with paying for
poor quality power, staff recommends that the Board authorize the additional work, to
be performed by GHD on a Time and Materials basis as an Amendment to their existing
Task Order #2 in an amount not to exceed $26,000.
SCHEDULE: As soon as possible
COSTS: $26,000

South Tahoe Public Utility District (STPUD)
1275 Meadow Crest Dr.
South Lake Tahoe, CA 96150
Julie,
GHD is submitting this fee proposal amendment request in order to continue providing professional
engineering services to prepare a Power Quality Study associated with the Luther Pass Pump Station.
Background
The District executed Amendment F to Task Order No. 2 on May 4, 2017 for GHD to provide electrical
engineering services to develop a Power Quality Study for Luther Pass Pump station. The current
approved fee for Amendment F to Task Order No. 2 is $54,956.
GHD’s original proposal included the assumption that the District would retrieve power quality data and
deliver the data to GHD in a mutually agreed to format.
Since initiating the project, GHD has been evaluating power quality data provided by the District. During
the power quality data evaluation process, GHD began to note that there were irregularities in the power
quality data provided by the District. Specifically, GHD noted that there were long durations of incomplete
power quality data sets where the data was essentially blank (data gaps).
Since noting the data gaps, GHD has been working with the District and the SCADA historian vendor
(Wonderware) in an attempt to resolve the issue with gaps in the retrieved data.
On 5/10/18, GHD met with the District, the District’s SCADA representative (Primex) and Wonderware to
develop a solution to enable power quality data to be extracted from the District’s SCADA Historian. The
meeting resulted in a workable solution provided by Wonderware that will enable the necessary data to be
extracted so that GHD can complete the power quality study.
Since the meeting on 5/10/18, The District has acquired the services of Primex to assist the District in
extracting the required power quality data from the SCADA Historian.
16
To-date, GHD has expended approximately $52,000 of the original budget of $54,956 issued as
Amendment F of task order No. 2. GHD’s time spent to-date on the Amendment F scope of work has
included parsing data provided by the District, evaluating partial power quality data sets, assisting the
District in attempting to extract data from the SCADA historian, and providing project management
support.
In order to complete the power quality study, GHD is requesting a change to the original amendment cost
to make-up for the effort spent to-date assisting the District with gathering data and resolving issues with
the data provided by the District, which was not anticipated in the original proposed effort.
The following list is the LPPS task breakdown and status of previously authorized GHD tasks:
Task 1 - Project Management (COMPLETE)
Task 2, 3 and 4 - LPPS BODR (COMPLETE)
Task 5, 6, 7, 8, 9, 10, 11, 12 & 13 - LPPS Design (COMPLETE)
Task 14 - Funding Application Support (COMPLETE)
Task 15 - WWTP Transformer Evaluation and Design (COMPLETE)
Task 16, 16.1, 16.2 and 16.3 – Bid Phase Services (COMPLETE)
Task 17 and 17.1 – Construction Support Services (COMPLETE)
Task 17.2 – Office Engineering Services, Amendment C – Task Order 2 (NOT COMPLETE)
Task 17.2 currently has approximately $32,000 remaining of the original $446,157 budgeted for GHD
Office Engineering Services. Of the remaining budget, approximately $18,000 is set aside for developing
as-built drawings, which has yet to be initiated, pending delivery of the field marked-up drawings by the
contractor.
Proposed Amendment Change
The scope of work outlined within the original Amendment F to Task Order No. 2 is expected to remain
unchanged, with the exception that GHD intends to increase the evaluated data from 1.0 years’ worth of
data to a duration of 1.5 years.
In order to complete the Power Quality Study, GHD is requesting a supplemental amendment amount of
$40,000.
GHD would like to propose using the remaining Task 17.2 budget of approximately $14,000 to complete
the power quality study, which if permitted by the District to do so would require an additional amendment
of $26,000 to complete the work in progress.
The timeframe for completing the power quality study is anticipated to be 12-weeks of receiving the
complete District furnished power quality data.

BOARD AGENDA ITEM 4c
TO: Board of Directors
FROM: John Thiel, Engineering Department Manager
MEETING DATE: August 2, 2018
ITEM – PROJECT NAME: 2017 Fire Hydrant Service Expansion and Large Meter
Replacement Project
REQUESTED BOARD ACTION: Approve Change Order No. 3 to White Rock Construction
for the 2017 Fire Hydrant Service Expansion and Large Meter Replacement Project in
the amount of $19,957.38 and to extend the Contract Time by 55 days.
DISCUSSION: Change Order No. 3 addresses one final additional work item at the Fallen
Leaf Lake Sewer System which was not included in the original Contract and one item
to extend the Contract Time to complete this work.
The District directed White Rock Construction (White Rock) to complete this additional
work at Fallen Leaf Lake Sewer System because the District’s staff was fully engaged on
other projects, the needs were immediate due to the onset of homeowner and visitor
traffic at Fallen Leaf Lake, and the District’s ambitious schedule to continue the
abandonment of the problematic sewer vacuum system and replacement with new
electrical pump stations. Furthermore, this particular site was very challenging due to
steep slope, proximity to a power pole, and limited site constraints, as well as the need
for experience and equipment necessary for retaining wall construction.

BOARD AGENDA ITEM 6a
TO: Board of Directors
FROM: Julie Ryan, Principal Engineer
MEETING DATE: August 2, 2018
ITEM – PROJECT NAME: David Lane Booster Station Improvements
REQUESTED BOARD ACTION: Approve Proposal from Carollo Engineers for engineering
services in an amount not to exceed $215,300 to design mechanical and electrical
improvements for the David Lane Booster Station.
DISCUSSION: In May 2017, the Board authorized Task Order No. 8 for Carollo Engineers
(Carollo), to provide, in part, an assessment and design of water efficiency
improvements for seven of the District’s highest energy consuming booster stations.
One of those stations was the David Lane Booster Station, which serves most of the City
of South Lake Tahoe east of Pioneer Trail and Highway 50 interesection, including the
Heavenly Resort California Base Lodge and snow-making operations.
The initial assessment concluded that not only is David Lane Booster Station in need of
instrumentation to allow better monitoring of pump efficiency and power consumption,
but also that the station would benefit greatly from new switchgear and an optimized
pumping system. The David Lane Pump Station also has several other needs, outside of
the scope of Carollo’s assessment.
• The station has been included on the Capital Improvement Plan for several years
to add improvements to the station’s emergency power capabilities.
• This past Spring, staff performed a pump efficiency test of the three pumps at the
station, and found pump 2 to fall short of expectation. Follow-on inspection
found severe damage to the impellor and pump casing interior.
• The station has a shake shingle roof, in need of replacement for fire protection.
• Staff has been in discussion with the California Tahoe Conservancy about the
proposed route of a multi-use pathway behind the station. To accommodate
this path, the rear and right side parcel boundaries would be adjusted.

The proposed project will address all of these station deficiencies.
Because of their familiarity with the Station’s needs, staff has requested that Carollo
provide a Proposal (attached) to design the mechanical and electrical improvements
for the station (including instrumentation). To make the best use of staff expertise, and
provide the best value to the District, civil and structural improvements for the Project
will be designed by District staff, and are excluded from Carollo’s Proposal.
The David Lane Booster Station Improvements Design will be performed as Task 13
under the District’s existing Master Services Agreement with Carollo. Staff recommends
that the Board authorize Task 13 in an amount not to exceed $215,300. This effort will be
funded, in part, by the El Dorado County Water Agency, pending approval of the
2018/19 Project List.
SCHEDULE: As soon as possible
COSTS: $215,300

TASK ORDER NO. 13
DAVID LANE BOOSTER PUMP STATION
IMPROVEMENTS PROJECT
South Tahoe Public Utility District
Background
The David Lane Booster Pump Station (David Lane BPS) boosts potable water from the Stateline Zone up
into the June Way Zone for general public use (year-round) and commercial snowmaking (during the winter
months). Historic water demand for the pump station ranges between approximately 280 gallons per
minute for domestic use (with a maximum day demand of 500 gpm), and 1,250 gpm when snow-making
demands are added. The District relies on David Lane BPS, in combination with the smaller Keller Booster
Pump Station, to deliver water to 707 of its 14,132 customers. David Lane BPS typically delivers 100 MG per
year, approximately 5% of the total annual water served by the District.
CONSULTANT is working on a Water Efficiency Improvements Project that aims to identify (and implement)
energy efficiency improvements at seven (7) of the District’s water distribution sites with the highest
historical power consumption, including the David Lane BPS. The District spends more money on power at
David Lane BPS than at any other booster station. The goals of the Water Efficiency Improvements Project
are as follows:
• To facilitate data collection for the site (through related flow, pressure, and power monitoring) to
inform future efficiency improvements
• To evaluate (and recommend) improvements to the pumping regime and other existing equipment
for near-term reduction of energy consumption
• To address demand variability issues
Through site investigation and ongoing (related) efforts with the District, it has been determined that facility
improvements at this station are necessary (in excess of those originally identified by the District for
enhanced energy efficiency). Upgrades discussed herein will provide for enhanced operational flexibility,
optimized energy consumption, and long-term system reliability. Additionally, packaging all improvements
in one contractor bid set (including planned standby generator improvements) will reduce the operational
impact (due to down time for construction) and enable efficiencies in the overall cost for design and
construction of improvements.
Scope of Services
The Scope of Services for this project (and the associated fee estimate) is based on a project scoping call
with the District (February 12, 2018) and follow-on conversations, and includes engineering services
associated with design and coordination of the following David Lane Pump Station improvements:
• Modification and/or replacement of existing pumps
• Replacement of switchgear and all downstream wiring and conduit
o Switchgear to be configured with automatic transfer switch and quick connects to facilitate
generator use (as needed)
34
TASK ORDER NO. 13
PAGE 2 of 5
• Replacement of flow and/or pressure instruments per recommendations of Final Water Efficiency
Upgrade Project BODR.
• Communication system upgrades recommended in the recent Communication Study (Carollo, final
report addendum pending), with the following additional improvements per District request:
o New PLC and RTU systems, configured for local facility control and collection of the
following data for transmission to the District’s SCADA network: flow, pressure, and energy
use metrics (kW, kWh, real-time efficiency monitoring). The feasibility of implementing the
following control modes will also be evaluated: “tank turnover mode” and “time-of-use
mode”.
CONSULTANT will complete planning and design of proposed improvements at the David Lane BPS. This
effort will consist of the following tasks.
Task 1 – Project Management and Meetings
CONSULTANT will develop and implement administrative procedures that will be used to plan and monitor
the progress of the project through the duration of the contract.
Task 1.1 – Project Administration. The overall project scope, schedule, budget, and subconsultant
coordination will be managed under this task. This task includes the preparation of monthly progress reports
to keep the DISTRICT informed about CONSULTANT’S project progress, including comparison of baseline
scope, budget, and schedule metrics against current activities. The fee associated with this task assumes
project completion within twelve (12) months.
Task 1.2 – Project Kickoff Meeting. CONSULTANT will lead a Project Kickoff Meeting at the DISTRICT’s
office, and prepare advance agenda with discussion topics, information needs list, and necessary
decisions/feedback to limit project delay. CONSULTANT will also prepare minutes summarizing workshop
discussion with decisions memorialized in a Decision Log that will be updated through project completion.
Task 1.3 – Project Progress Calls. CONSULTANT will coordinate monthly conference calls to report project
progress by the team, discuss any issues that may arise over the course of the project, and receive DISTRICT
feedback regarding preferred direction. The fee associated with this task assumes that progress calls will not
be conducted on months that design review workshops are scheduled.
Task 1.4 – Design Review Workshops. CONSULTANT will lead design review workshops with the purpose of
communicating design intent to the DISTRICT’s staff and collecting feedback regarding design
modifications for the associated deliverable. Project challenges and issues will be discussed and addressed
during these meetings. The fee associated with this task assumes participation of 3 CONSULTANT staff at
each of the following design review workshops:
• Draft Basis of Design Report Review Workshop
• 60% Design Review Workshop
• 90% Design Review Workshop
Task 1 Deliverables: Project progress reports, monthly invoices, meeting minutes.
TASK 2 – Basis of Design Report
Carollo will prepare a Basis of Design Report (BODR) that documents existing conditions, project goals,
design criteria, and alternative analyses including cost comparisons of key project elements,
recommendations, project implementation, and schedule. At a minimum, the BODR will address the
following items:
35
TASK ORDER NO. 13
PAGE 3 of 5
• Detailed analysis of the pump alternatives recommended in the in the Water Efficiency Upgrade
Project BODR. These include:
o Option 1: 2-1,250 gpm, 30 HP; 1-500 gpm, 75 HP (replace two existing pumps with larger
pumps and motors)
o Option 2: 3-500 gpm, 75 HP (replace Pump 2 in-kind)
o Option 3: 1-1,250 gpm, 300 HP; 2-500 gpm, 75 HP (replace one existing pump with larger
pump and motor)
The option that provides the most advantageous upgrade (in terms of energy efficiency, reliability of
operation, and overall cost) will be recommended for implementation.
• Pipe replacement needs to accommodate a reduced liquid velocity from 8 feet per second (fps)
to 5 fps, consistent with the District’s standard for design of new pipes under normal flow
conditions.
• Preliminary site layout with size and location of major mechanical equipment locations.
• Starting analysis for large pumps (300 HP).
• Electrical system sizing, and preliminary layout of system upgrades. This will include an electrical
system sizing with use of soft-starts on large pumps (300 HP), as appropriate.
• Options for differently sized emergency standby generators (not permanently housed on-site),
including replacement of the existing 250 KW generator plug (as needed), and addition of a
second plug for a larger standby generator (to be sized based on final load following selection of
pump upgrade options).
• Control system options (programmable logic controllers, instruments, communications and
control logic).
• Estimated construction schedule and construction sequencing plan.
• Estimate of probable construction costs for facility upgrades.
CONSULTANT’s internal quality management program will be initiated during the preparation of the BODR.
The BODR will be submitted for DISTRICT review, and a preliminary design review workshop will be
organized to obtain DISTRICT feedback (per Task 1.4). DISTRICT comments on the Draft BODR will be

BOARD AGENDA ITEM 6b
TO: Board of Directors
FROM: Julie Ryan, Principal Engineer
MEETING DATE: August 2, 2018
ITEM – PROJECT NAME: Main Zone District Metered Areas
REQUESTED BOARD ACTION: Approve Proposal from Carollo Engineers for engineering
services in an amount not to exceed $82,600 to design District Metered Areas within the
Main Zone of the Water Distribution System.
DISCUSSION: In August 2017, the Board authorized Task Order No. 11 for Carollo
Engineers (Carollo), to provide hydraulic modeling services for the water distribution
system. Because of their familiarity with the District’s water model, gained over the last
year, staff has requested that Carollo now provide a proposal (attached) to use the
water model to develop a plan to break the District’s Main Zone into District Metered
Areas (DMA’s) to allow future tracking of water losses within this area. The proposal also
includes design of a prototype flow monitoring station, which can be deployed in the
field in the future, as funding becomes available.
With the installation of customer meters well underway, and advanced metering
infrastructure (AMI) online, for the first time the District will be able to track consumption
of water by its customers. To fully leverage the power of the AMI system, which provides
consumption data in real-time (on an hourly basis), the Engineering Department
recommends that the District develop a Water Loss Tracking System. This tracking
system would use flow meters to measure the quantity of water delivered to defined
areas of the distribution system, and compare the quantity delivered to the quantity
consumed within that area through all the new customer meters to identify real water
losses. A Water Loss Tracking System will have multiple benefits to the District:
• help the District reduce water losses
• help pinpoint leak response efforts
• help extend the life of its buried assets
• facilitate active management of system pressures
• meet new State Standards for the Water Loss Tracking

There are nearly 7,000 customers in the Main Zone, and more than 100 miles of water
main, making it difficult to use zone-wide water loss data to help pinpoint leaks. Staff
expects that there will be between 8 and 12 DMA’s established within the Main Zone
(with 16 to 30 monitoring stations) at full buildout. Each monitoring station is expected
to consist of a vault (containing a flow meter) and an above-grade control panel
(housing control and communication devices). The DMA’s could be installed all at
once, or in phases, depending on funding availability.
The DMA design will be performed as Task 12 under the District’s existing Master Services
Agreement with Carollo. Staff recommends that the Board authorize Task 12 in an
amount not to exceed $82,600. This effort will be funded, in part, by the El Dorado
County Water Agency, pending approval of the 2018/19 Project List.

TASK ORDER NO. 12
STATELINE ZONE DMA DEMARCATION
South Tahoe Public Utility District
Background
The DISTRICT has proposed the creation of district metered areas (DMAs), each consisting of 500 to 2,000
service connections within the Stateline/Main Zone. This would result in the creation of between 4 and 20
DMAs, allowing the DISTRICT to isolate (and repair) leakage within the distribution system. The goal will be
to configure each DMA so that it is served through two pipelines (each equipped with flow metering), thus
maximizing hydraulic conditions for reliable supply to each DMA and allowing the close monitoring of water
loss within the DMA.
Scope of Services
As requested by the DISTRICT, CONSULTANT will provide support for development of the Stateline DMAs
through a series of interactive steps. This will consist of the following tasks.
Task 1 – Conceptual Layout of DMAs
In coordination with DISTRICT staff, CONSULTANT will develop up to three (3) conceptual layouts for
recommended DMAs within the Stateline Zone. The intention for the conceptual layouts is that each DMA
will be served by two pipelines, each connected to the transmission main located outside of the DMAs.
CONSULTANT will identify the isolation valves that would need to be closed and locations for isolation valves
to create the DMAs. In the development of these conceptual layouts, CONSULTANT will evaluate options that
maximize flow into the DMA. CONSULTANT will hold an on-site meeting with DISTRICT staff to discuss the
proposed DMAs and collect initial feedback.
•Task 1 Deliverables: Map of Proposed DMAs (electronic)
Minutes from Conceptual DMA Layout Review Workshop (electronic)
Task 2 – Initial Hydraulic Modeling of DMAs
After approval of the conceptual layouts for the DMAs by DISTRICT staff (Task 1), CONSULTANT will
perform hydraulic modeling for the DMAs within each conceptual layout. The model runs will consist of:
•Maximum day demand (MDD) at existing conditions to identify system pressures and ability for
tanks to refill prior to formation of the DMAs (baseline)
•MDD with DMAs to identify degradation in system pressures and ability for tanks to refill due to
creation of DMAs
•MDD plus fire flow at existing conditions to identify existing fire flow conditions
•MDD plus fire flow with DMAs to identify degradation in the ability to deliver fire flow due to
creation of the DMAs
One conference call will be held with the DISTRICT to discuss initial hydraulic modeling results.
•Task 2 Deliverables: Maps showing system pressures and fire flow delivery capacity with and
without DMAs (electronic)
43
TASK ORDER NO. 12
PAGE 2 of 4
Task 3 – Modification of DMAs
After the initial hydraulic model runs are completed, CONSULTANT will propose modifications to the DMAs
to minimize their impact to system pressures, tank refilling, and fire flow delivery and update the hydraulic
model results accordingly.
CONSULTANT will present the modified DMAs to the DISTRICT via conference call and collect associated
feedback.
• Task 3 Deliverables: Updated MDD maps for system pressure and fire flow (electronic)
Task 4 – Confirmation of DMAs
After there is general agreement on the DMA layout, CONSULTANT will develop and run water age model
runs of the DISTRICT’s distribution system, one with and one without the proposed DMAs. Water age will be
used as a proxy for water quality; thus, the goal for this exercise will be to confirm that the DMAs will not
have a significant increase in water age due to the creation of DMAs. CONSULTANT has included budget for
one additional modification to the DMAs and updating the maps.
• Task 4 Deliverables: Map for water age under existing system conditions and with DMAs, updated
maps with system pressure and fire flow
Task 5 – Review of Flow Metering Technology and Communication Options
CONSULTANT will review the available flow metering technology to measure flow for use in calculating
water loss within the developed DMAs. As a function of this task, CONSULTANT will investigate
communication options appropriate for transmitting flow data to the DISTRICT’s supervisory control and
data acquisition (SCADA) system. It is assumed, based on recent (related) efforts associated with the
Pressure Reducing Valve (PRV) Upgrade Project BODR, that data transfer will be accomplished through
cellular communication, though additional effort is warranted here to determine whether data collection will
be better served (for this purpose) through the DISTRICT’s advanced metering infrastructure (AMI) network.
CONSULTANT will prepare a matrix of up to three (3) different flow metering technologies and three (3)
communication options (including cellular, AMI, and radio), for DISTRICT review/feedback. For this
evaluation, it is assumed the DISTRICT will connect to existing nearby utility power connections and/or seek
new service through the power utility.
This task will include the development of options for installing the metering vaults within the DMA service
areas, with consideration to the DISTRICT’s existing standards.
CONSULTANT will present the flow metering and communication options to the DISTRICT, along with
metering vault options and recommendations, via conference call.
Findings and recommendations for this task will be delivered as described in Task 6.
Task 6 – Basis of Design Report
CONSULTANT will prepare a Draft Basis of Design Report (BODR) summarizing the findings and
recommendations for efforts completed under Tasks 1 through 5, as well as a draft cost estimate for
construction of proposed improvements (including comparative costs for Task 5 items). The cost estimates
will be based on available quantity take-offs, manufacturer’s quotes, and experience incorporating similar
project elements in other projects. Estimates will be prepared to a level of accuracy consistent with the
standards of the AACE International.
44
TASK ORDER NO. 12
PAGE 3 of 4
CONSULTANT will present the findings and recommendations at a BODR Workshop, where the DISTRICT’s
comments will be collected for incorporation into a preliminary set of typical design details, and into the
Final BODR (following DISTRICT review/approval of the typical design details).
CONSULTANT will prepare a preliminary set of typical design details for a prototype station based on
DISTRICT-feedback received during the BODR Workshop. The design details will be prepared for the
DISTRICT’s use/modification (as necessary) to procure the construction of up to 20 similar stations
envisioned for the Stateline Main Zone (via DISTRICT-prepared bid documents and a District-designated
engineer as Engineer of Record). The design details (structural/mechanical and electrical/instrumentation)
will incorporate selected facility options discussed at the BODR Workshop, and a draft set will be prepared
for District review/feedback. District comments received on the draft design details will be incorporated into
a final set of design details, which will be submitted in electronic (CAD) format and also incorporated into
the Final BODR.
The Final BODR will incorporate DISTICT feedback received at the BODR Workshop, final typical design
details, and an updated cost estimate.
• Task 6 Deliverables: Draft Basis of Design Report (electronic)
Final Basis of Design Report (electronic, plus 10 hardcopies)
Task 7 – Project Management and Meetings
CONSULTANT will perform the overall management of the project defined herein following
CONSULTANT’s typical procedures for resource allocation, scheduling of work, quality assurance/quality
control, and invoicing. The overall project scope, schedule, and budget will be managed under this task.
This task includes preparation of monthly progress reports to keep the DISTRICT informed about
CONSULTANT’S project progress, including comparison of baseline scope, budget, and schedule metrics
against current activities.
The budget associated with this task includes two (2) on-site meetings with DISTRICT staff (as identified in
Tasks 1 and 5), up to four (4) conference calls (as identified in Tasks 2, 3, and 5, plus one additional for as-
needed discussion), and project completion within six (6) months.
• Task 7 Deliverables: Project progress reports, monthly invoices.
Assumptions/Exclusions
This Scope of Services is based on the following assumptions and exclusions:
• The fee associated with this scope considers the development of design details for all DMAs as one
concerted effort, occurring over a 6-month (maximum) period from receipt of Notice to Proceed to
submittal of the final BODR.
• Project deliverables will include the Draft BODR, preliminary typical design details, and the Final
BODR. The fee associated with this scope does not include the preparation of design drawings,
review of District-prepared design packages, or bid/construction phase assistance. Typical design
details will not include provisions necessary to capture and integrate the instrument signals into
SCADA.
• No environmental documentation and/or permit efforts are included in this Scope of Services.

BOARD AGENDA ITEM 6c
TO: Board of Directors
FROM: Daniel Arce, Laboratory Director
MEETING DATE: August 2, 2018
ITEM – PROJECT NAME: Ion Chromatograph Instrument Purchase
REQUESTED BOARD ACTION: 1) Find the High Pressure Ion Chromatograph from Thermo
Scientific, to be the sole brand instrument for use in the District Laboratory; and,
2) Authorize purchase of the High Pressure Ion Chromatograph instrument from the sole
provider, Thermo Fisher Corporation, in the estimated amount of $ 61,811, plus sales tax.
DISCUSSION: The Laboratory’s (Lab) current Ion Chromatograph instrument was
purchased in 2007. It is the primary instrument the Lab uses to measure nutrients such as
Nitrates and Phosphates. These are crucial to regular monitoring of the wastewater
treatment process as well as measuring the District’s quality of recycled water delivered
to Alpine County. In particular, Indian Creek Reservoir has strict regulatory requirements
regarding Phosphate which must therefore be measured at very low levels. The District’s
yearly monitoring of Drinking Water Wells also requires that the Lab measure many
anions at low concentrations which include chemicals like Fluoride, Bromide and
Chloride.
The District used to have a Service Contract Agreement with Dionex which provides
phone support as well as occasional preventive maintenance visits for the Lab’s current
instrument. Dionex informed the District earlier this year that they will no longer support
this instrument.
Ion Chromatographs require that the column used be replaced periodically at a cost of
approximately $1,000. The rate at which the Lab’s current instrument uses these
columns has increased dramatically from approximately one per year to approximately
one every four months.
Staff recommends the purchase of the High Pressure Ion Chromatograph unit from
Thermo Fisher Scientific because it is a superior unit with which the Lab staff is familiar
and for which some parts and consumables can be shared with the old instrument.

The Laboratory staff, therefore, requests that the Board approve the purchase of a new
High Pressure Ion Chromatograph at an estimated cost of $61,811, plus tax. The
Laboratory will maintain the current instrument in working order so that staff may still use
it for monitoring of chemistries which do not require very low detection limits such as soil
extracts.
This item has been reviewed by the District’s Purchasing Agent.
