BOARD AGENDA ITEM 4a
TO: Board of Directors
FROM: Adrian Combes, Director of Operations
MEETING DATE: December 4, 2025
ITEM – PROJECT NAME: Lead Service Line Inventory
REQUESTED BOARD ACTION: 1) Approve Task Order No. 1A to Truepani, Inc. in the
amount of $18,100; and 2) Authorize General Manager to execute Task Order No. 1A.
DISCUSSION: The District is required under the Lead and Copper Rule to prepare a lead
service line inventory which identifies the material of water services on both the District
side of the meter and customer side of the meter. The District issued a Request for
Proposals (RFP) at the end of 2024 to engage a consultant to assist with the preparation
of the baseline inventory, develop a workplan to be approved by the Department of
Drinking Water, provide field survey support and prepare final reporting. The District
issued Task Order No. 1 to prepare the initial inventory and workplan.
The purpose of this item is to approve the remaining work which includes updating the
final inventory, preparing a final report and presentation, and continued project
management. The District did not utilize the consultant to assist with developing a plan
for the field surveys which saved approximately $30,000 from the original proposal. The
cost for the remaining amount of work to complete the inventory is $18,100. Staff
recommend that this Task Order amendment be approved so that the inventory may
be completed and submitted before the end of the calendar year.

BOARD AGENDA ITEM 6a
TO: Board of Directors
FROM: Adrian Combes, Director of Operations
MEETING DATE: December 4, 2025
ITEM – PROJECT NAME: Public Health Goals Report
REQUESTED BOARD ACTION: Hold a Public Hearing at 2:01 p.m. to receive public
comments regarding the 2025 Public Health Goals Report.
DISCUSSION: A Public Health Goals Report is required to be prepared by July 1, 2025, for
water utilities that have greater than 10,000 service connections and their water quality
measurements have exceeded any Public Health Goals (PHGs). PHGs are non-
enforceable goals established by the California Environmental Protection Agency (Cal
EPA) Office of Environmental Health Hazard Assessment (OEHHA). Public Health Goals
are different from Maximum Contaminant Levels (MCLs - the legal maximum level for
any contaminant in drinking water). Public Health Goals do not take into account
available treatment technologies, detection technology, or cost, whereas MCLs do
take those things into account.
If a constituent was detected in the South Tahoe Public Utility District’s (District) water
supply between 2022 and 2024 at a level exceeding an applicable PHG or Maximum
Contaminant Level Goal (MCLG), this report provides the information required by law.
Included is the numerical public health risk associated with the MCL and the PHG or
MCLG, the category or type of risk to health that could be associated with each
constituent, the best treatment technology available that could be used to reduce the
constituent level, and an estimate of the cost to install that treatment if it is appropriate
and feasible.

PUBLIC HEALTH
GOALS REPORT
SOUTH TAHOE PUBLIC UTILITY DISTRICT
JUNE 2025
Background
Provisions of the California Health and Safety Code §116470(b) specify that larger (> I0,000 service
connec#ons) water u#li#es prepare a special report by July I, 2025 if their water quality measurements
have exceeded any Public Health Goals (PHGs). PHGs are non-enforceable goals established by the
California Environmental Protec#on Agency (Cal EPA) Office of Environmental Health Hazard Assessment
(OEHHA). The law also requires that where OEHHA has not adopted a PHG for a cons#tuent, the water
suppliers are to use the maximum contaminant level goals (MCLG) adopted by the United States
Environmental Protec#on Agency (US EPA). Only cons#tuents which have a California primary drinking
water standard and for which either a PHG or MCLG has been set are to be addressed. (Reference No. 2
is a list of all regulated cons#tuents with the MCLs and PHGs or MCLGs).
There are a few cons#tuents that are rou#nely detected in water systems at levels usually well below the
drinking water standards for which no PHG nor MCLG has yet been adopted by OEHHA or US EPA
including Total Trihalomethanes. These will be addressed in a future required report a;er a PHG has
been adopted.
If a cons#tuent was detected in the South Tahoe Public U#lity District’s (District) water supply between
2022 and 2024 at a level exceeding an applicable PHG or MCLG, this report provides the informa#on
required by the law. Included is the numerical public health risk associated with the MCL and the PHG or
MCLG, the category or type of risk to health that could be associated with each cons#tuent, the best
treatment technology available that could be used to reduce the cons#tuent level, and an es#mate of
the cost to install that treatment if it is appropriate and feasible.
What Are Public Health Goals?
Public Health Goals (PHGs) are set by the California Office of Environmental Health Hazard Assessment
(OEHHA) which is part of Cal-EPA and are based solely on public health risk considera#ons. None of the
prac#cal risk-management factors that are considered by the US EPA or the California Division of
Drinking Water in se?ng drinking water standards (MCLs) are considered in se?ng the PHGs. These
factors include analy#cal detec#on capability, treatment technology available, benefits and costs. The
PHGs are not enforceable and are not required to be met by any public water system. MCLGs are the
federal equivalent to PHGs.
Water Quality Data Considered
All the water quality data collected by South Tahoe Public U#lity District between 2022 and 2024 for
purposes of determining compliance with drinking water standards was considered. This data was all
summarized in our 2022, 2023, and 2024 Consumer Confidence Reports. (Reference No. 3)
Guidelines Followed
The Associa#on of California Water Agencies (ACWA) formed a work group which prepared guidelines for
water u#li#es to use in preparing these newly required reports. The ACWA guidelines were used in the
prepara#on of our report. No guidance was available from state regulatory agencies.
Best Available Treatment Technology and Cost Es#mates
Both the US EPA and California Division of Drinking Water (DDW) adopt what are known as BATs or Best
Available Technologies which are the best-known methods of reducing contaminant levels to the
maximum contaminant level (MCL). Costs can be es#mated for such technologies. However, since many
PHGs and all MCLGs are set much lower than the MCL, it is not always possible nor feasible to determine
what treatment is needed to further reduce a cons#tuent downward to or near the PHG or MCLG, many
of which are set at zero. Es#ma#ng the costs to reduce a cons#tuent to zero is difficult, if not impossible.
It is some#mes not possible to verify by analy#cal means that the level has been lowered to zero. In
some cases, installing treatment to try and further reduce very low levels of one cons#tuent may have
adverse effects on other aspects of water quality.
Cons#tuents Detected That Exceed a PHG or a MCLG
The following is a discussion of cons#tuents that were detected in one or more of the District’s drinking
water sources at levels above the PHG, or if no PHG, above the MCLG.

Arsenic
The contamina#on of a drinking water source by arsenic can result from either natural or human
ac#vi#es. Arsenic is an element that occurs naturally in rocks and soil, water, air, plants and animals.
Volcanic ac#vity, the erosion of rocks and minerals, and forest fires are natural sources that can release
arsenic into the environment. Although about 90 percent of the arsenic used by industry in the United
States is used for wood preserva#ve purposes, arsenic is also used in paints, drugs, dyes, soaps, metals
and semi-conductors. Burning fossil fuels and waste, paper produc#on, glass manufacturing, cement
manufacturing, mining and smel#ng can also release arsenic. While arsenic can no longer be used in
making pes#cides and weed killers, the US EPA is aware that these substances have contributed to
drinking water contamina#on.
The PHG for Arsenic is 0.004 micrograms per liter (ug/L or parts per billion). The MCL or drinking water
standard for arsenic is 10 ppb. The District detected arsenic levels above the PHG but not exceeding the
MCL in the discharge from eight (8) District Wells listed below. The average of the samples taken
between 2022 and 2024 are shown in the table below.
Well Arsenic (ppb)
2022 - 2024 Average
Arrowhead #3* 3.2
Bakersfield 8.2
Bayview 2.0
Elks Club #2 1.3
Helen #2 6.2
South Upper Truckee #3 1.7
Sunset 3.8
Valhalla 1.9
* Arrowhead Well #3 is equipped with wellhead treatment for Arsenic removal and the level reported is a;er
treatment
Some people who drink water containing arsenic in excess of EPA’s standard over many years may
experience skin damage or circulatory system problems and may have an increased risk of ge?ng cancer.
OEHHA has determined that the health risk associated with arsenic is an increased risk of cancer.
Numerical health risk data provided by OEHHA determined the health risk associated with the PHG is
one (1) excess case of cancer in a million people and the health risk associated with the MCL is two and a
half (2.5) excess cases of cancer in 1,000 people over life#me of exposure.
The best available technology for arsenic treatment is Ac#vated Alumina, Coagula#on/Filtra#on, Lime
So;ening, Ion Exchange and Reverse Osmosis. These treatment methods would require more
consulta#on beyond the scope of this report to determine the appropriate treatment for each well site.
Some of the well sites do not have enough land to install/construct a wellhead treatment facility,
therefore acquisi#on of land and associated piping to the facility would be required.
For the purpose of this report, adsorp#on using iron oxide will be selected because that is what the
District u#lizes at the Arrowhead Well to remove arsenic. Treatment for the wells listed above (excluding
Arrowhead Well #3) is es#mated to have an annualized capital and opera#on and maintenance (O&M)
cost could range from approximately $3,000,000 to $4,000,000 per year1. That would result in an
assumed increased cost for each water customer ranging from $215 to $285 per year.
1 Estimate based on Cost Estimates for Treatment Technologies from 2012 ACWA Survey
Uranium
Uranium is a naturally occurring radioac#ve element that is found in many types of rocks. Uranium is
found in ground and surface waters due to its natural occurrence in geological forma#ons.
The PHG for Uranium (U) is 0.43 picoCuries per liter (pCi/L). The MCL or drinking water
standard for Uranium is 20 pCi/L. The District detected uranium levels above the PHG but not exceeding
the MCL in the discharge from ten (10) District Wells listed below. The average of the samples taken
between 2022 and 2024 are shown in the table below:
Well Uranium (pCi/L)
2022 - 2024 Average
Al Tahoe #2 1.18
Arrowhead #3 13.4
Bakersfield 8.57
Bayview 0.92
Elks Club #2 1.67
Glenwood #5 5.87
Helen #2 7.37
South Upper Truckee #3 0.78
Sunset 8.03
Valhalla 0.93
Some people who drink water containing uranium in excess of the MCL over many years may have
kidney problems or an increased risk of ge?ng cancer. Numerical health risk data provided by OEHHA
determined the health risk associated with the PHG is one (1) excess case of cancer in a million people
and the health risk associated with the MCL is five (5) excess cases of cancer in 100,000 people over
life#me of exposure.
The best available technology for Uranium treatment is Coagula#on/Filtra#on, Ion Exchange, Lime
So;ening and Reverse Osmosis. These treatment methods would require more consulta#on beyond the
scope of this report to determine the appropriate treatment for each well site. Some of the well sites do
not have enough land to install/construct a wellhead treatment facility, therefore acquisi#on of land and
associated piping to the facility would be required.
For the purpose of this report, ion exchange will be selected for treatment. The disposal of the spent
media for Uranium treatment is complex due to the radioac#ve nature of the element which can result
in a wide range in O&M cost. Ion Exchange for the wells listed above is es#mated to have an annualized
capital and O&M cost could range from approximately $4,000,000 to $8,000,000 per year2. That would
result in an assumed increased cost for each water customer ranging from $286 to $571 per year.
2 Estimate based on Cost Estimates for Treatment Technologies from 2012 ACWA Survey
PFOA
Star#ng in the 1940s, perfluorooctanoic acid (PFOA) was widely used in industrial applica#ons and
consumer products, including carpets, rugs, upholstered furniture and non-s#ck cookware. PFOA has
also been present in some firefigh#ng foams used at airports, firefighter training facili#es and military
airfields. Notably, PFOA in nons#ck cookware and PFOS in stain and water-repellant fabrics and in fire-
figh#ng foams. The manufacture of these chemicals was phased out in the US following concerns about
their extreme persistence in the environment and their detec#on in virtually all human blood serum
samples, however, may s#ll be present in some imported products. Although levels in the environment
have declined from their peak around the year 2000, PFOA and PFOS con#nue to be present in the
environment and are found in California drinking water.
The US EPA’s MCL for PFOA is 4 ppt (parts-per-trillion), and the PHG for PFOA is 0.007 ppt. The District
detected PFOA levels above the PHG but not exceeding the MCL in the discharge from one (1) District
Well listed below. The average of the samples taken between 2022 and 2024 are shown in the table
below:
Helen Well #2 – 3.1 ppt
OEHHA has determined that the health risk associated with PFOA is an increased risk of cancer.
Numerical health risk data provided by OEHHA determined the health risk associated with the
PHG is one (1) excess case of cancer in a million people.
The best available technology for PFOA treatment is Ion exchange, granular ac#vated carbon, reverse
osmosis and nanofiltra#on. These treatment methods would require more consulta#on beyond the
scope of this report to determine the appropriate treatment.
For the purpose of this report, granulated ac#vated carbon will be selected for treatment. The capital
cost for granulated ac#vated carbon wellhead treatment would likely be between $3,000,000 to
$5,000,000 due to the need for a building and poten#ally addi#onal land. That would result in an
assumed increased cost for each water customer ranging from $15 to $21 per year.
Recommenda#ons For Further Ac#on
The drinking water quality of the South Tahoe Public U#lity District meets all State of California, Division
of Drinking Water, and US EPA drinking water standards set to protect public health. To further reduce
the levels of the cons#tuents iden#fied in this report that are already significantly below the health-
based Maximum Contaminant Levels established to provide “safe drinking water,” addi#onal costly
treatment processes would be required. The effec#veness of the treatment processes to provide any
significant reduc#ons in cons#tuent levels at these already low values is uncertain. The health protec#on
benefits of these further hypothe#cal reduc#ons are not clear and may not be quan#fiable. The District
is developing a Water Supply Master Plan and evalua#ng public health goals and poten#al for wellhead
treatment be considered as a part of that process.

2022, 2023 AND 2024
South Tahoe Public Utility District
C O N S U M E R C O N F I D E N C E R E P O R T 2 O 2 2
IS MY WATER SAFE? Yes. Last year, as in years
past, your tap water met all U.S.
Environmental Protection Agency (EPA)
and state drinking water health standards.
The South Tahoe Public Utility District
vigilantly safeguards its water supplies, and
we are proud to report that our source
water has not violated a maximum
contaminant level or any other water
quality standard.
Some people may be more vulnerable
to contaminants in drinking water than
the general population. Immuno-
compromised persons such as persons
with cancer undergoing chemotherapy,
persons who have undergone organ
transplants, people with HIV/AIDS or other
immune system disorders, some elderly,
and infants can be particularly at risk
from infections. These people should seek
advice about drinking water from their
health care providers. EPA/Centers for
Disease Control (CDC) guidelines on
appropriate means to lessen the risk of
infection by Cryptosporidium and other
microbial contaminants are available
from the USEPA’s Safe Water Drinking
Hotline (1-800-426-4791).
WHERE DOES MY WATER COME FROM? There
are 11 active drinking water wells and 4
standby wells which supply more than
14,000 homes and businesses. All our
drinking water is pumped from
underground aquifers. No water is taken
from Lake Tahoe or any other surface
water source.
SOURCE WATER ASSESSMENT AND
PROTECTION The District continues to work
diligently to protect and maintain our
groundwater quality and adequate water
supply. The District’s Groundwater
Management Plan (California Water Code
Section 10750) was adopted on
December 4, 2014, and is on file with the
California Department of Public Health
(CDPH).
You may view the document by visiting
the District’s website at www.stpud.us or
by requesting a copy by calling Customer
Service at 530-544-6474.
The District has an ongoing drinking
water source development program that
seeks potential drinking water well
locations. Due to the volume of the
average annual Sierra snowpack and
Lake Tahoe itself, our aquifer has a
significant recharge capability.
HOW DO CONTAMINANTS GET INTO
DRINKING WATER? Drinking water, including
bottled water, may reasonably be
expected to contain at least small amounts
of some contaminants. The presence of
contaminants does not necessarily indicate
that water poses a health risk. More
information about contaminants and
potential health effects can be obtained
by calling the Environmental Protection
Agency's (EPA) Safe Drinking Water Hotline
(1-800-426-4791). The sources of drinking
water (both tap water and bottled water)
include rivers, lakes, streams, ponds,
reservoirs, springs, and wells. As water
travels over the surface of the land or
through the ground, it dissolves naturally
occurring minerals and, in some cases,
radioactive material, and can pick up
substances resulting from the presence of
animals or from human activity. Microbial
contaminants, such as viruses and bacteria,
may come from sewage treatment plants,
septic systems, agricultural livestock
operations, and wildlife. Inorganic
contaminants, such as salts and metals,
can be naturally occurring or result from
urban stormwater runoff, industrial, or
domestic wastewater discharges, oil and
gas production, mining, or farming.
Pesticides and herbicides may come from
a variety of sources such as agriculture,
urban stormwater runoff, and residential
uses. Organic chemical contaminants,
including synthetic and volatile organic
chemicals, are by-products of industrial
processes and petroleum production, and
can also come from gas stations, urban
stormwater runoff, agricultural application,
and septic systems. Radioactive
contaminants can be naturally occurring
or be the result of oil and gas production
and mining activities. Many of these
contamination sources do not exist in Lake
Tahoe. In order to ensure that tap water is
safe to drink, the United States
Environmental Protection Agency (USEPA)
and the California Department of Public
Health (DPH) prescribe regulations that limit
the amount of certain contaminants in
water provided by public water systems.
Food and Drug Administration (FDA)
regulations establish limits for contaminants
in bottled water which must provide the
same protection for public health.
HOW CAN I FIND OUT MORE? The information
contained in the Consumer Confidence
Report may not answer all the questions
you may have about the quality of the
South Tahoe Public Utility District’s drinking
water supply. If you would like more
detailed information, please call the
District Laboratory at 530-543-6231 or
check our website at www.stpud.us.
The District is governed by an elected
five-member Board of Directors. Board
meetings are held on the first and third
Thursday of each month at 2 p.m. at the
Customer Service Facility located at 1275
Meadow Crest Drive. All meetings are open
to the public and the District
encourages our customers to attend, ask
questions, and provide feedback.
RESULTS OF RADON MONITORING Radon is a
radioactive gas that cannot be seen,
tasted, or smelled. It is found throughout
the U.S. Radon can move up through the
ground and into a home through cracks
and holes in the foundation. Radon can
build up to high levels in all types of homes.
Radon can also get into indoor air when
released from tap water from showering,
washing dishes, and other household
activities. Compared to radon entering the
home through soil, radon entering the
home through tap water will, in most cases,
be a small source of radon in indoor air.
Radon is a known human carcinogen.
Breathing air containing radon can
lead to lung cancer. Drinking water
containing radon may cause an increased
risk of stomach cancer. If you are
concerned about radon in your home, you
can test the air in your home. For
additional information on radon, call your
state radon program or the EPA’s Radon
Hotline (800-SOS-RADON).
RESULTS OF VOLUNTARY MONITORING
See data sheets.
REGARDING ARSENIC Arsenic is a naturally
occurring substance that is sometimes
found at low levels in drinking water,
particularly groundwater. The South Tahoe
Public Utility District has an active Arsenic
monitoring program, as well as a pilot
Arsenic removal system in one of its wells.

WATER QUALITY DATA TABLE The table below lists all
the drinking water contaminants detected
which are applicable for the calendar year of
this report. The presence of contaminants in the
water does not necessarily indicate that the
water poses a health risk. Unless otherwise
noted, the data
presented in this table is from testing done in
the calendar year of the report. The EPA or
the State requires us to monitor for certain
contaminants less often than once per year
because the concentrations of these
contaminants do not change frequently.
ADDITIONAL CONTAMINANTS In an effort to ensure
the safest water possible, the State has required
us to monitor some contaminants not required
by Federal regulations. Of those contaminants
only the ones listed on the last page under
“Additional Contaminants” were found in your
water.

SOCs (Synthetic Organic Compounds) are mostly human-
made carbon-based chemicals. They are used as pesticides,
defoliants, fuel additives and as ingredients in the
manufacture of many other compounds. Some of the more
well-known ones include PCBs, Atrazine, Florene, Dioxins and
Caffeine. SOC’s health effects include damage to the
nervous system and cancer risks. The District last tested for
these chemicals in 2021.
ADDITIONAL MONITORING As part of an ongoing evaluation
program called UCMR (Unregulated Contaminant Monitoring
Rule), the Environmental Protection Agency requires the
District to monitor a number of additional contaminants/
chemicals. Information collected through this monitoring
provides information for future decisions on drinking water
standards.
UCMR-3 The District was required to monitor our source water
for 28 chemical contaminants. The first round was completed
in August 2014 and the second round in February 2015. In the
absence of identifiable industrial sources, these contaminants
are naturally occurring in our watershed. Chlorate is an
exception and is a degradation product of the disinfectant
used by the District for drinking water.
UCMR-4 In this round of UCMR, the District was required to
monitor for 18 chemical contaminants, as well as the Total
Organic Carbon (TOC) content in our Source Water. The first
round was completed in January 2019 and the second round
in July 2019. These contaminants included metals like
Germanium, volatile Pesticides and their byproducts such as
alpha-HCH, volatile Alcohols like 1-Butanol and Tar/Oil
byproducts like Quinoline.
The District also tested its distribution system for 9 disinfection
byproducts, collectively known as Haloacetic Acids (HAA9).

IS MY WATER SAFE?
Yes. Last year, as in years past, your tap
water met all U.S. Environmental
Protection Agency (EPA) and state
drinking water health standards. The
South Tahoe Public Utility District
(District) vigilantly safeguards its water
supplies, and we are proud to report
that our source water has not violated
a maximum contaminant level or any
other water quality standard.
Some people may be more
vulnerable to contaminants in drinking
water than the general population.
Immuno-compromised persons such
as persons with cancer undergoing
chemotherapy, persons who have
undergone organ transplants, people
with HIV/AIDS or other immune system
disorders, some elderly people, and
infants can be particularly at risk from
infections. These people should seek
advice about drinking water from
their health care providers.
EPA/Centers for Disease Control
(CDC) guidelines on appropriate
means to lessen the risk of infection
by Cryptosporidium and other
microbial contaminants are available
from the EPA’s Safe Water Drinking
Hotline(1-800-426-4791).
WHERE DOES MY WATER COME FROM?
The District’s network of 11 active and 2
standby wells supplies water to over
14,000 homes and businesses. All
drinking water is pumped from the
aquifer beneath our feet – the Tahoe
Valley South Subbasin. More information
about our aquifer and groundwater
management can be found at
www.stpud.us/drinking-water.
SOURCE WATER ASSESSMENT AND
PROTECTION
The District continues to work diligently
to protect and maintain our
groundwater quality and adequate
water supply. The District’s Groundwater
Management Plan (California Water
Code Section 10750) is on file with the
California Department of Public Health
(CDPH). You may view the document
by visiting the District’s website at
www.stpud.us or by requesting a copy
by calling Customer Service at 530-544-
6474. The District has an ongoing
drinking water source development
program that seeks potential drinking
water well locations. Due to the volume
of the average annual Sierra snowpack
and Lake Tahoe itself, our aquifer has a
significant recharge capability.
HOW DO CONTAMINANTS GET INTO
DRINKING WATER?
Drinking water, including bottled water,
may reasonably be expected to
contain at least small amounts of some
contaminants. The presence of
contaminants does not necessarily
indicate that water poses a health risk.
More information about contaminants
and potential health effects can be
obtained by calling the Environmental
Protection Agency’s Safe Drinking
Water Hotline (800-426-4791). The
sources of drinking water (both tap
water and bottled water) include rivers,
lakes, streams, ponds, reservoirs, springs,
and wells. As water travels over the
surface of the land or through the
ground, it can dissolve naturally
occurring minerals and, in some cases,
radioactive materials, and can pick up
substances resulting from the presence
of animals or from human activity.
Microbial contaminants, such as viruses
and bacteria, may come from sewage
treatment plants, septic systems,
agricultural livestock operations, and
wildlife. Inorganic contaminants, such as
salts and metals, can be naturally
occurring or result from urban storm
water runoff, industrial or domestic
wastewater discharge, oil and gas
production, mining, or farming.
Pesticides and herbicides may come
from a variety of sources such as
agriculture, urban storm water runoff,
and residential uses. Organic chemical
contaminants, including synthetic and
volatile organic chemicals, are by-
products of industrial processes and
petroleum production, and can also
1
South Tahoe Public Utility District
C O N S U M E R C O N F I D E N C E R E P O R T 2 O 2 3
come from gas stations, urban storm
water runoff, and septic systems.
Radioactive contaminants can be
naturally occurring or be the result of oil
and gas production and mining
activities. In order to ensure that tap
water is safe to drink, EPA prescribes
regulations which limit the amount of
certain contaminants in the water
provided by public water systems. The
Food and Drug Administration (FDA)
regulations establish limits for
contaminants in bottled water which
must provide the same protection for
human health.
RADON MONITORING
Radon is a naturally occurring gas
present in some groundwater. Inhaled
radon has been linked to lung cancer
and may pose a health risk when
inhaled after the release from water into
the air. This inhalation could occur
during showering, bathing, washing
dishes, or washing clothes. The radon
gas released from drinking water is a
relatively small part of the total radon
found in air. One major source of radon
gas is from the soil, where the gas can
seep through the foundations of homes.
It is not clear whether ingested (i.e.
taken through the mouth) radon
contributes to cancer or other adverse
health conditions. If you are concerned
about radon in your home, tests are
available to determine the total
exposure level. For additional
information on home testing call your
state radon program or EPA’s Radon
Hotline (800-SOS-RADON).
REGARDING ARSENIC
While your drinking water meets EPA’s
standard for arsenic, it does contain
low levels of arsenic. EPA’s standard
balances the current understanding of
arsenic’s possible health effects
against the costs of removing arsenic
from drinking water. EPA continues to
research the health effects of low
levels of arsenic, which is a mineral
known to cause cancer in humans at
high concentrations and is linked to
other health effects such as skin
damage and circulatory problems.
INFORMATION ABOUT LEAD
If present, elevated levels of lead can
cause serious health problems,
especially for pregnant women and
young children. Lead in drinking water
is primarily from materials and
components associated with service
lines and home plumbing. The District is
responsible for providing high quality
drinking water but cannot control the
variety of materials used in plumbing
components. When your water has
been sitting for several hours, you can
minimize the potential for lead
exposure by flushing your tap for 30
seconds to 2 minutes before using the
water for drinking or cooking. If you are
concerned about lead in your water,
you may wish to have your water
tested. Information on lead in drinking
water, testing methods, and steps you
can take to minimize exposure is
available from the Safe Drinking Water
Hotline or at
www.epa.gov/safewater/lead.
HOW CAN I FIND OUT MORE?
If you would like more detailed
information on your drinking water,
please call Dan Arce in the District
Laboratory at 530-544-6474 x6231 or
check our website at www.stpud.us.
The District is governed by an
elected five-member Board of
Directors. Board meetings are held on
the first and third Thursday of each
month at 2 p.m. at 1275 Meadow Crest
Drive, South Lake Tahoe. All meetings
are open to the public and the District
encourages our customers to attend,
ask questions, and provide feedback.

WATER QUALITY DATA TABLE The table below lists
the drinking water contaminants monitored for
the calendar year of this report. The presence
of contaminants in the water does not
necessarily indicate that the water poses a
health risk. Unless otherwise noted, the data
presented in this table is from testing done in
the calendar year of the report. The EPA or
the State requires us to monitor for certain
contaminants less often than once per year
because the concentrations of these
contaminants do not change frequently.
ADDITIONAL CONTAMINANTS In an effort to ensure
the safest water possible, the State has required
us to monitor some contaminants not required
by Federal regulations. These contaminants are
listed on Page 5 under “Additional Monitoring”.
None were found in your water.

ADDITIONAL MONITORING As part of an ongoing evaluation
program called UCMR (Unregulated Contaminant Monitoring
Rule), the Environmental Protection Agency (EPA) requires
water agencies to monitor additional
contaminants/chemicals. Data collected through this
monitoring provides information for future decisions on
drinking water standards.
UCMR-5 Water agencies are required to sample for 30
additional chemicals between 2023 and 2025. This includes
the metal Lithium and 29 chemicals collectively known as
PFAS (per- and polyfluoroalkyl compounds). For a detailed
explanation on the toxicity of these chemicals please visit:
www.epa.gov/pfas. The District sampled each of its water
sources at least two times between 2023 and 2024. Some
sources were sampled more often to confirm results.
NATIONAL PFAS STANDARDS In April 2024, the EPA established
drinking water standards for five specific PFAS chemicals,
including Maximum Contaminant Levels (MCL). The MCLs and
monitoring results are expressed in Parts per Trillion (ppt). One
part per trillion is equivalent to one second in 32,000 years. Of
the drinking water wells tested, only one of the regulated
chemicals (PFOA) was detected at one well. This well was
tested four times in 2023/2024 and this chemical was below
the EPA MCL limit three out of the four times. This well supplied
less than 5% of the District’s drinking water in 2023.

Presented By
South Tahoe Public Utility District
Our Commitment
The South Tahoe Public Utility District (District) is pleased to present to you this year’s annual water quality
report. This report is a snapshot of last year’s water quality covering all testing performed between January 1
and December 31, 2024. Included are details about your sources of water, what it contains, and how it compares to
standards set by regulatory agencies. Our constant goal is to provide you with a safe and dependable supply of drink-
ing water. We want you to understand the efforts we make to continually improve and protect our water resources.
Where Does My Water Come From?
The District’s network of 11 active wells supplies water
to over 14,000 homes and businesses. All your drink-
ing water is pumped from the aquifer beneath our feet – the
Tahoe Valley South Subbasin. More information about our
aquifer and groundwater management can be found at stpud.
us/drinking-water.
Important Health Information
Some people may be more vulnerable to contami-
nants in drinking water than the general population.
Immunocompromised persons such as persons with cancer
undergoing chemotherapy, persons who have undergone organ
transplants, people with HIV/AIDS or other immune system
disorders, some elderly, and infants, can be particularly at risk
from infections. These people should seek advice about drink-
ing water from their health-care providers. U.S. Environmental
Protection Agency (U.S. EPA)/Centers for Disease Control
and Prevention (CDC) guidelines on appropriate means to
lessen the risk of infection by Cryptosporidium and other
microbial contaminants are available from the Safe Drinking
Water Hotline at (800) 426-4791 or epa.gov/safewater.
Substances That Could Be in Water
The sources of drinking water (both tap water and bottled
water) include rivers, lakes, streams, ponds, reservoirs,
springs, and wells. As water travels over the surface of the
land or through the ground, it dissolves naturally occurring
minerals and, in some cases, radioactive material and can pick
up substances resulting from the presence of animals or from
human activity.
Contaminants that may be present in source water include:
Microbial Contaminants, such as viruses and bacteria, that
may come from sewage treatment plants, septic systems,
agricultural livestock operations, and wildlife.
Inorganic Contaminants, such as salts and metals, that can be
naturally occurring or result from urban stormwater runoff,
industrial or domestic wastewater discharges, oil and gas
production, mining, or farming.
Pesticides and Herbicides that may come from a variety of
sources such as agriculture, urban stormwater runoff, and
residential uses.
Organic Chemical Contaminants, including synthetic and
volatile organic chemicals, that are by-products of industrial
processes and petroleum production and can also come from
gas stations, urban stormwater runoff, agricultural application,
and septic systems.
Radioactive Contaminants that
can be naturally occurring or the
result of oil and gas production
and mining activities.
To ensure that tap water is safe
to drink, the U.S. EPA and the
State Water Resources Control
Board (SWRCB) prescribe
regulations that limit the amount
of certain contaminants in
water provided by public water
systems. U.S. Food and Drug
Administration regulations and California law also establish
limits for contaminants in bottled water that provide the same
protection for public health.
Drinking water, including bottled water, may reasonably
be expected to contain at least small amounts of some
contaminants. The presence of contaminants does not
necessarily indicate that water poses a health risk. More
information about contaminants and potential health effects
can be obtained by calling the U.S. EPA’s Safe Drinking Water
Hotline at (800) 426-4791.

this report, or for any questions
relating to your drinking water, please call Dan Arce,
Laboratory Director, at (530) 544-6474, ext. 6231.
Source Water Assessment and Protection
The District continues to work diligently to protect and maintain our groundwater quality and an adequate water sup-
ply. The District’s Groundwater Management Plan (California Water Code, section 10750) is on file with the California
Department of Public Health (CDPH). You may view the document by visiting the District’s website at stpud.us or request a
copy by calling customer service at (530) 544-6474. The District has an ongoing drinking water source development program
that seeks potential drinking water well locations. Due to the volume of the average annual Sierra snowpack and Lake Tahoe
itself, our aquifer has a significant recharge capability.
Groundwater in South Lake Tahoe is generally of excellent quality, though it has faced threats from both natural and human-
made contaminants. Methyl tert butyl ether (MTBE) and tetrachloroethylene (PCE) plumes in the South Y area led the
District to remove affected wells from service and develop new, uncontaminated sources. Naturally occurring arsenic, uranium,
and gross alpha particle activity have been found in parts of the aquifer, with one District well requiring arsenic treatment to
meet water quality standards. Infiltration basins used for stormwater recharge also pose potential risks, but these are effectively
managed through careful well siting, design, and wellhead treatment.
Testing for Radon
Our wells were last monitored for radon in 2023 and test results were below the maximum contaminant level (MCL). Radon is
a naturally occurring radioactive gas that you cannot see, taste, or smell. It is found throughout the U.S. Radon can move up
through the ground and into a home through cracks and holes in the foundation. Radon can build up to high levels in all types of
homes. Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activi-
ties. Compared to radon entering the home through soil, radon entering the home through tap water will, in most cases, be a small
source in indoor air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water
containing radon may also cause increased risk of stomach cancer. If you are concerned about radon, test the air in your home. Testing
is inexpensive and easy. You should pursue radon removal if the level of radon in your air is 4 picocuries per liter (pCi/L) of air or
higher. There are simple ways to fix a radon problem. For additional information, call California’s Radon Program at (800) 745-7236,
the U.S. EPA’s Safe Drinking Water Hotline at (800) 426-4791, or the National Safety Council Radon Hotline at (800) 767-7236.
Community Participation
The District is governed by an elected five-member board of directors. Board meetings are held on the first and third Thursday of
each month at 2:00 p.m. in the District boardroom at 1275 Meadow Crest Drive. All meetings are open to the public, and the
District encourages our customers to attend, ask questions, and provide feedback.
What Are PFAS?
Per- and polyfluoroalkyl substances (PFAS) are a group of
manufactured chemicals used worldwide since the 1950s
to make fluoropolymer coatings and products that resist heat,
oil, stains, grease, and water. During production and use,
PFAS can migrate into the soil, water, and air. Most PFAS do
not break down; they remain in the environment, ultimately
finding their way into drinking water. Because of their wide-
spread use and their persistence in the environment, PFAS are
found all over the world at low levels. Some PFAS can build
up in people and animals with repeated exposure over time.
The most commonly studied PFAS are perfluorooctanoic acid
(PFOA) and perfluorooctanesulfonic acid (PFOS). PFOA and
PFOS have been phased out of production and use in the
United States, but other countries may still manufacture and
use them.
Some products that may contain PFAS include:
• Some grease-resistant paper, fast food containers/wrappers,
microwave popcorn bags, pizza boxes
• Nonstick cookware
• Stain-resistant coatings used on carpets, upholstery, and
other fabrics
• Water-resistant clothing
• Personal care products (shampoo, dental floss) and
cosmetics (nail polish, eye makeup)
• Cleaning products
• Paints, varnishes, and sealants
Even though recent efforts to remove PFAS have reduced the
likelihood of exposure, some products may still contain them.
If you have questions or concerns about products you use in
your home, contact the Consumer Product Safety Commission
at (800) 638-2772. For a more detailed discussion on PFAS,
please visit atsdr.cdc.gov/pfas/index.html.
Arsenic Regulation
Arsenic contamination of drinking water sources may
result from either natural or human activities. Volcanic
activity, erosion of rocks and minerals, and forest fires are
natural sources that can release arsenic into the environment.
Although about 90 percent of the arsenic used by industry is
for wood preservative purposes, it is also used in paints, drugs,
dyes, soaps, metals, and semiconductors. Agricultural applica-
tions, mining, and smelting also contribute to arsenic releases.
Arsenic is usually found in the environment combined with
other elements such as oxygen, chlorine, and sulfur (inorganic
arsenic) or carbon and hydrogen (organic arsenic). Organic
forms are usually less harmful than inorganic forms.
Low levels of arsenic are naturally present in water--about 2
parts arsenic per billion parts water (ppb), so you normally
take in small amounts of arsenic in the water you drink.
Some areas of the country have unusually high natural levels
of arsenic in rock, which can lead to unusually high levels of
arsenic in water.
In January 2001, the U.S. EPA lowered the arsenic MCL from
50 to 10 ppb in response to new and compelling research
linking high arsenic levels in drinking water with certain forms
of cancer. All water utilities were required to implement this
new MCL in January 2006.
Removing arsenic from drinking water is a costly procedure but
well worth the expenditure considering the health benefits. For
a more complete discussion, visit the U.S. EPA’s arsenic web
page, epa.gov/dwreginfo/drinking-water-arsenic-rule-history.
Test Results
The following tables list the drinking water contaminants monitored for the calendar year of this report, unless otherwise noted. The presence of contaminants in the water does not
necessarily indicate that the water poses a health risk. The U.S. EPA and SWRCB require us to monitor for certain contaminants less often than once per year based on results of
previous testing. The District monitors for more contaminants than are listed in these tables. Contaminants not detected during testing are not shown in the tables.
The state recommends monitoring for certain substances less than once per year because the concentrations of these substances do not change frequently. In these cases, the most recent
sample data is included, along with the year in which the sample was taken.
The District participated in the fifth stage of the U.S. EPA’s Unregulated Contaminant Monitoring Rule (UCMR5) program by performing additional tests on our drinking water. UCMR5
sampling benefits the environment and public health by providing the U.S. EPA with data on the occurrence of contaminants suspected to be in drinking water to determine if it needs
to introduce new regulatory standards to improve drinking water quality. Unregulated contaminant monitoring data is available to the public, so please feel free to contact us if you are
interested in obtaining that information. If you would like more information on the U.S. EPA’s Unregulated Contaminant Monitoring Rule, please call the Safe Drinking Water Hotline
at (800) 426-4791 or visit https://www.epa.gov/dwucmr/learn-about-unregulated-contaminant-monitoring-rule.

Lead in Home Plumbing
Lead can cause serious health effects in people of all ages, especially
pregnant people, infants (both formula-fed and breastfed), and
young children. Lead in drinking water is primarily from materials
and parts used in service lines and in home plumbing. The District
is responsible for providing high-quality drinking water and remov-
ing lead pipes but cannot control the variety of materials used in
the plumbing in your home. Because lead levels may vary over time,
lead exposure is possible even when your tap sampling results do not
detect lead at one point in time. You can help protect yourself and
your family by identifying and removing lead materials within your
home plumbing and taking steps to reduce your family’s risk. Using a
filter certified by an American National Standards Institute-accredited
certifier to reduce lead is effective in reducing lead exposures. Follow
the instructions provided with the filter to ensure it is used properly.
Use only cold water for drinking, cooking, and making baby formula.
Boiling does not remove lead from water.
Before using tap water for drinking, cooking, or making baby formula,
flush your pipes for several minutes. You can do this by running your
tap, taking a shower, or doing laundry or a load of dishes. If you have
a lead or galvanized service line requiring replacement, you may need
to flush your pipes for a longer period. If you are concerned about lead
and wish to have your water tested, contact the District’s laboratory
at (530) 544-6474, ext. 6231. Information on lead in drinking water,
testing methods, and steps you can take to minimize exposure is
available at epa.gov/safewater/lead.
To address lead in drinking water, public water systems were required
to develop and maintain an inventory of service line materials by
October 16, 2024. Developing an inventory and identifying the
location of lead service lines is the first step for beginning to replace
lead service lines and protecting public health. While no lead water
service lines have been identified in the District’s system to date,
service lines with unknown materials are still being assessed. More
information about the District’s lead service inventory may be found at
stpud.us/water-service-line-inventory. Please contact us at (530) 544-
6474 if you would like more information about the inventory or lead
sampling that has been done.
Public Health
Goals Report -
2025
Adrian Combes
Director of Operations
Public Health Goals Overview
•The California Health and Safety Code requires that water
districts with more than 10,000 service connections prepare a
special report if their water quality measurements exceed any
Public Health Goals.
•Public Health Goals are non-enforceable goals established by
California EPA’s Office of Environmental Health Hazard
Assessment.
•Public health goals are based solely on public health risk
considerations and do not consider practical risk management
factors like detection capability, treatment technology available,
benefits and costs.
•As a water district, we are required to meet maximum
contaminant levels (MCLs), but not public health goals.
Public Health Goals vs. MCLs
•Maximum Contaminant Levels (MCL) are set by the U.S.
Environmental Protection and by the California State Water
Resources Control Board.
•An MCL is the highest level of a contaminant that is legally
permitted in public drinking water.
•MCLs are set based on the best available technology for
treatment, detection capability, benefits, and costs.
•As a water district, we are required to meet maximum
contaminant levels (MCLs), but not public health goals.

MEETING DATE: December 4, 2025
ITEM – PROJECT NAME: Sewer Force main Hydraulic Analysis and Air Release Valve
Assessment
REQUESTED BOARD ACTION: (1) Approve the proposed Scope of Work by Schaaf and
Wheeler for Force main Hydraulic Analysis and Air Release Valve Assessment; and (2)
Authorize the General Manager to execute Task Order No. 1 with Schaaf and Wheeler
in the amount of $254,133.
DISCUSSION: The South Tahoe Public Utility District (District) owns and operates 40
wastewater pump stations connected through approximately 48 miles of force main
piping. Much of this infrastructure was constructed between 1955 and 1971 and
includes numerous air release, vacuum, and combination air/vacuum valves (ARVs)
that are essential to maintaining reliable force main operation and preventing air
entrainment, surging, and other hydraulic instabilities. Many of these assets are at or
beyond their expected service life and require varying levels of rehabilitation or
replacement in the near future.
To address these challenges, the District advertised a Request for Proposals (RFP) and
received one Proposal from Schaaf & Wheeler, Consulting Civil Engineers (Shaaf &
Wheeler) to perform a comprehensive Force main Hydraulic Analysis and ARV
Assessment. District staff worked with Shaaf & Wheeler to refine the scope of this effort
and the proposed work will evaluate the hydraulic performance and operational risks
associated with 25 selected force mains and pump stations, identify deficiencies in ARV
functionality or placement, and develop a prioritized Rehabilitation and Replacement
(R&R) Plan for implementation in the District’s Capital Improvement Program (CIP).

The proposed scope of work includes four primary tasks:
(1) Data collection and review;
(2) Force main and ARV hydraulic and transient analysis;
(3) Development of a prioritized rehabilitation and replacement plan including
standard details, technical specifications, and operation and maintenance
procedures; and
(4) Project management and coordination.
The resulting deliverables will provide the District with a data-driven understanding of
system risks, detailed improvement recommendations, and standardized design and
maintenance resources for future ARV projects.
The total fee for this work is $254,133 on a time-and-materials, not-to-exceed basis.
Execution of the Master Services Agreement with Schaaf & Wheeler will be completed
prior to execution of this Task Order. Work is anticipated to begin in December 2025 and
be completed by December 2026.
This assessment represents a critical first step toward modernizing the District’s
pressurized wastewater conveyance system, improving operational reliability, and
extending the service life of key infrastructure assets.

Project Summary
The South Tahoe Public Utilities District (District) currently owns, maintains, and operates 40
wastewater pump stations, covering approximately 48 miles of force main in the District.
Construction materials for the existing force mains include asbestos cement, steel, and PVC pipe
with ~139 air release valves that have been cataloged to date.
Most of the existing force mains were constructed between 1955 and 1971. Exceptions to this
include the Fallen Leaf Lake force mains (constructed between 1979 and 1983) and the Flanders,
Gardner Mountain, Ponderosa, and Ski Run force mains, which were constructed after 1997. The
District needs evaluation, assessment, and planning for near term capital improvements for force
mains and associated air release valves, vacuum valves, and combination air/vacuum valves
(collectively referred to as ARVs) that need to be added or are at or beyond their design life. The
District specific goals for this project includes the following:
▪ Force Main Operation Reliability
o Confirm the quantity and location of ARVs
o Confirm the functionality of existing ARVs
o Identify hydraulic inefficiencies and operational risks for selected force mains
▪ Prioritization of Capital Improvements
o Provide short-term and long-term improvement and maintenance projects based
on observed condition and modeled performance assessment of force mains and
ARVs
▪ System Optimization
o Identify locations where new ARVs are needed including sizing recommendations
o Identify locations where existing ARVs can be removed or relocated
▪ Constructability and Practical Long-Term Maintenance Strategies
o Develop strategies to minimize cost and system disruption
o Assess the constructability and associated costs for selected sites and
improvement strategies
o Review station specific bypassing or flow storage methods required for selected
sites
o Provide detailed template technical specifications and standard details to be
used for future improvement projects
The District provided Schaaf & Wheeler with additional data for review including ARV records, as-
built drawings, GIS data, and the sanitary sewer master plan. We will provide a preliminary

Project Scope
Based on the Request For Proposal and the District identified needs, Schaaf & Wheeler proposes
the following scope of services.
Task 1: Data Collection and Review
The consultant will gather and review the available provided by the District. This task will rely on
the existing knowledge of the District for system as a prelude to any authorized field work by
Schaaf & Wheeler. The District will perform the initial field work based on the results of Task 1.2
and at the consultant’s request.
Task 1.1: Data Collection and Review
Schaaf & Wheeler will review available data, including existing sewer force main as-built
drawings, profiles, and operational SCADA data. This includes our review of the District sewer
model(s) to additionally identify transient modeling data needs.
Task 1.2: Data Gap Identification and Request List
We will submit a data request to the District that identifies data gaps for the selected pump stations
and force mains in Exhibit B. The District will review and prepare any additional data and field
work that is reasonable to find and collect.
Task 1.3: Data Gathering Results Technical Memorandum (Draft/Final)
A draft Data Gathering Results Technical Memorandum will be prepared and submitted to the
District for review. The memorandum will organize and present the collected and reviewed data
and will include data gaps and the workplan assumptions for filling those gaps as needed to
complete Task 2. The memorandum will also document Schaaf & Wheeler ’s recommendations
for methodology and software for force main transient analysis.
Schaaf & Wheeler will incorporate the District review comments into a final memorandum that will
confirm the pump station and force main analysis performed in Task 2.
Task 1.4 (Optional): Additional Field Reconnaissance and/or Meetings
Schaaf & Wheeler has allocated up to one week of optional field reconnaissance effort as needed
to fill data gaps that are found from the initial data review or for specific ARV’s identified in Exhibit
B that need observation and data collection. It is likely that any authorized field work by the
consultant would occur in the Spring of 2026.

Task 2: Force Main/ARV Analysis
Schaaf & Wheeler will perform a hydraulic analysis, including transient conditions, for the 25
identified sewer pump stations and force mains to verify that existing ARVs are properly located,
sized, potential ARV abandonment, and to identify potential new locations for ARVs.
Recommendations for changes in valve type, size, location, and access will be included in a draft
technical memorandum for the District review and comment.
Task 2.1: Develop Force Main Models and Surge Analysis
Schaaf & Wheeler will conduct a hydraulic and transient analysis of the selected pump stations
and force mains using the method, data, and assumptions identified in Task 1. The results will be
used in Task 2.2 and for developing the technical memorandum in Task 2.3.
Task 2.2: Develop ARV Sizing and Type
Recommended valve sizes for existing and potential new ARVs will be provided. The risks for
over pressurization or vacuum conditions will be identified based on the results of the hydraulic
and transient analysis in Task 2.1.
Task 2.3 : Develop Analysis Results, Findings, and Recommendations Technical
Memorandum
The technical memorandum will include methodology for valve assessment, maps and figures
showing valve locations, recommended valve sizing and valve types, supporting calculations, and
modeling output results will be prepared and submitted to the District for review and comments.
The District review comments will be incorporated into a final memorandum that will confirm the
pump station and force main analysis performed in Task 2.

Task 3.1: District Engagement on R&R Plan
We will engage with the District in developing the R&R Plan. This task assumes up to a total of
four virtual or in-person, one-hour meetings. This task includes the preparation for meetings and
meeting notes. These meetings are specific to the R&R Plan and incorporated into the general
coordination meetings in Task 4.2. The development of the R&R Plan is addressed in Tasks 3.2
through 3.4.
Task 3.2: Develop Risk Analysis, Conceptual Designs, Construction Sequencing, and
Approach Cost Analysis for R&R Plan
Schaaf & Wheeler will develop and review risk criteria and the results of Task 2 with the District
before prioritizing rehabilitation or replacement projects.
The R&R Plan will include conceptual designs and maintenance/construction sequences for
implementing rehabilitation projects without service interruptions. The R&R will include bypass
pumping and/or wet well storage constructability guidance to include:
• Bypass pumping plans or wet well detention for each recommended project
• Site-specific calculations for bypass flow and pump sizing
• Conceptual bypass pipe routing
• Safety considerations
• Backup and redundancy methods
Task 3.3: Develop Standard Details and Specifications for R&R (Draft/Final)
Schaaf & Wheeler will work with the District to develop templates for technical specifications and
standard details for District use in standardization of R&R projects. The standard details and
technical specifications will be suitable for incorporation into future contract documents for
improvement projects with minor alterations and edits. The technical specifications will
incorporate provisions for bypass pumping and/or holding flows at wet wells.
Task 3.4: R&R Approach Cost -Benefit Analysis and Engineers Opinion of Probable
Construction Costs (Draft/Final)

BOARD AGENDA ITEM 6d
TO: Board of Directors
FROM: Mark Seelos, Water Resources Manager
MEETING DATE: December 4, 2025
ITEM – PROJECT NAME: Relinquishment of Unused Legacy Water Rights
REQUESTED BOARD ACTION: Adopt Resolution No. 3324-25, revoking six unused water
rights on file with the State Water Resources Control Board.
DISCUSSION: With the acquisition of the Meyers Water Company and Tahoe Paradise
Water Company in the 1960s, the South Tahoe Public Utility Water District was granted
six water rights to the Upper Truckee River and a tributary of Saxon Creek. These rights
have never been used, and the licensed points of diversion lack infrastructure to divert,
treat, and distribute water. Thus, the District seeks to file formal requests to revoke these
water rights with the State Water Resources Control Board. The District is currently
pursuing a 10,808 acre-foot water right to Lake Tahoe under Water Rights Application
No. A023393.

A RESOLUTION BY THE BOARD OF DIRECTORS
OF THE SOUTH TAHOE PUBLIC UTILITY DISTRICT AUTHORIZING AND DIRECTING ITS STAFF
TO REQUEST THE REVOCATION OF CERTAIN SURFACE WATER RIGHTS
WHEREAS, the South Tahoe Public Utility District (“STPUD”) currently holds water
rights A018021, A018030, A018031, A018038, A018039, and A019629, originally
acquired from Tahoe Paradise Water Company, allowing for diversions from the
Upper Truckee River, Coyote Creek, and an unnamed tributary to Saxon Creek;
and
WHEREAS, STPUD has never developed facilities to divert, treat, or distribute water
under these water rights, and intake, treatment, and distribution infrastructure do
not exist; and
WHEREAS, due to water quality, quantity, and environmental constraints, it is not
cost-effective or practical to exercise these water rights, and the District is instead
pursuing a water right under A023393 to Lake Tahoe for 10,808 acre-feet; and
WHEREAS, in accordance with Water Code and State Water Resources Control
Board regulations, STPUD may request the revocation of water rights that are no

unexpected or high-priority infrastructure needs that arise during construction. The
District has successfully used As-Needed bid items in the past to complete critical work
with contractors who are already mobilized in the area, even when the work falls
outside the specific scope of their primary project. This approach minimizes mobilization
costs, shortens response time, and leverages existing contractor resources to address
issues before they escalate. The work described in this item is being completed under
the As-Needed Services bid schedule and was identified by District field staff based on
recent conditions in the system. This project is being brought forward as an unplanned
waterline improvement project due to the recent failure history and condition of the
existing main.
The proposed work includes installing approximately 545 feet of 12-inch C900 waterline
along Sacramento Avenue from El Dorado Avenue to Placer Avenue. The work
includes replacing two fire hydrants and six domestic water services, as well as two
system tie-ins and the abandonment of the existing steel water main.
Over the past month, the existing steel water main has experienced five leaks, two of
which occurred in an extremely shallow section of pipe. Because of the shallow depth,
these connections are exposed to live loading from vehicle traffic and will be further
stressed by snow removal equipment this winter. A failure at this location could result in
a major leak and flooding of nearby homes on El Dorado Avenue.

Historical records identify three earlier leaks on this segment; however, staff observed
two additional repair bands during recent work, indicating at least ten leaks have
occurred on this main. Replacement of the waterline is necessary to address the
immediate operational and liability risks and to remove aging steel infrastructure that is
not currently included in the 10-year CIP.
The anticipated contractor cost for this work is $300,100.

TO: Board of Directors
FROM: Richard Jones IV, Collections & Effluent Operations
Supervisor
MEETING DATE: December 4, 2025
ITEM – PROJECT NAME: 2026-2027 Sewer Line Spot Repair and Lateral Abandonment
Services
REQUESTED BOARD ACTION: 1) Reject all bids received for 2026-2027 Sewer Line Spot
Repair and Lateral Abandonment Services; and 2) Authorize staff to revise the bid
documents as needed to re-advertise the Project.
DISCUSSION: After publicly advertising on October 31, 2025, at 10:00 a.m. two bids were
received for Sewer Line Spot Repair and Lateral Abandonment Services. Bids were
opened on November 24, 2025 at 10:00 a.m. The apparent low bid has been deemed
non-responsive for failure to submit the bid documents electronically as required by the
Instruction to Bidders. The next lowest responsive bid substantially exceeds the
available budget and is not in the best interest of the District to award.
No contract award is recommended as rejection of both bids and re-advertising are in
the best interest of the District at this time. Re-advertising costs are minimal and within
the approved operating budget.
The District’s Purchasing Agent has reviewed this item.
SCHEDULE: Upon Board Approval
COSTS: TBD
ACCOUNT NO: 10.22.6055
BUDGETED AMOUNT AVAILABLE: $177,987.22 (2025/26); Assume similar budget for
(2026/27); $25,000/year from California Tahoe Conservancy

From: Kilty Devine, Purchasing Manager
Subject: 2026-27 Sewer Line Spot Repair and Lateral Abandonment Services Bid
Background
On Monday, November 24, 2025, at ten o’clock A.M. the District received and opened
two (2) sealed bids via the District’s electronic bidding format for the above-referenced
project. As read, bids ranged from $288,875.00 to $814,505. See attachment for the bid
tabulation.
Bid Review and Determination
Robotic Sewer Solutions, Inc. (RSS)- as-read low
• Determination: Non-Responsive
• Basis: RSS submitted its signed bid documents by mail rather than electronically
through PlanetBids, contrary to the solicitation requirement of “electronic
submission only” as outlined in the Invitation to Bid and the Instructions to
Bidders. This is a material deviation affecting the integrity of the competitive
process. The mailed hard-copy has been retained as part of the record.
Nor Cal Pipeline Services (NCPS)- as-read next low bidder
• Determination: Responsive
• Pricing: NCPS is 307% above the estimated bid value and exceeds the available
budget. Award at this price is not in the District’s best interest.
Recommendation
The recommendation is to reject all bids and re-advertise promptly.
