2. Tigard Tyler (T2) Update – Utility Billing Communications Plan Rollout
Darren Black shared an overview of the Tyler Utility Billing Communication Plan which
consists of four phases. This includes a summary of materials, outreach strategy and
intended goals.
The Tyler project is being framed under the City Council of Modernize and Improve City
Services. There will be common color themes and visual themes to help direct the public to
Tyler communication messaging. There are a lot of people who see these communications,
but never touch utility billing, and the City does not want to give them the sense there is
Water Advisory Board (WAB) Minutes
SERVING TIGARD WATER SERVICE AREA
Page 2 of 8
something they need to be doing right now. In terms of messages there are some key points,
one of which is the goal to get people to eventually switch to on-line billing. The emphasis
will not be on Tyler, at most it will be mentioned that it is powered by Tyler.
Web Content: This phase has already been completed, as of the end of March. The team
created a webpage that will act as the source of truth for any and all information related to
utility billing and Tyler upgrades. The page is up now.
Points of Contact and Communications: The idea is this would be a place where residents
could pay their utility bills manually. There are posters at the mail drop off locations; two
located at City Hall and there will be one in King City. There will be a phone recording set
up stating this change is coming in September. On the utility bill itself there will be a note
letting residents know this September there will be changes to their utility bill, and a message
directing them to the webpage if they have questions. That same note will be written in both
English and Spanish.
Outward Communications: The team is just getting started on this phase. The idea here is
this would be for the residents who pay their bill using the auto-pay option. The team is
putting together a mass email that will go out to anyone that does on-line bill pay. There will
be a tent set up at the farmers’ market to answer any questions. Over the summer the team
hopes to do a newsletter column, social media posts and another email blast.
Education and Training: will happen right around release time and a little bit afterwards. The
city cannot assume that new technology is intuitive so ample resources will be provided for
people to get any questions they have answered. There will be an instructional video up on
the webpage on how to set up accounts. The team is hoping to have a library session for
people who want to come in person and hope to soon have a user guide on the webpage.
Overall timeline essentially runs from March to September. March is phase one and most of
phase two and into April. Next month is phase three mostly rolling out social media posts,
reporting, etc. Over the summer, the team has not quite nailed down the dates for
communications, newsletter, mailer, and social media posts. Around August and September,
they will start pushing the educational content and anything else referenced here.
Mr. Black then talked about how the team will be measuring the success of this project. They
will have a focus group for the big-ticket utility bill payers, the ones who have huge utility
bills, probably business owners. They are also providing QR codes on information posters
and will track how often each QR code gets scanned. Each QR code is unique so they can
Water Advisory Board (WAB) Minutes
SERVING TIGARD WATER SERVICE AREA
Page 3 of 8
tell where each one is being scanned from. Most importantly we are counting views on the
webpage itself. The main goal is to get as many residents as possible to see that webpage.
Mr. Drake stated a lot of people out there do not know the City of Tigard bills for King
City. He asked if there is a way to have on the notice that utility billing covers City of Tigard,
Durham, King City, and the unincorporated area. Torri Porter responded that this made
sense. Mr. Brewin stated that all the other utilities have phone staff working Monday
through Friday. Tigard does not have staff working in Utility Billing on Friday’s and noted
that if a customer had their water turned off, or if they have billing questions, there is no one
available for them to talk to on Fridays. He asked if there is anyway someone at City Hall
can cover these issues on Fridays. Chair Walkiewicz stated that while this is a point to raise,
it is a question that cannot be answered in the WAB meeting. Darren Black mentioned,
besides Public Works the entire city works Monday through Thursday. A decision of that
magnitude would need to be addressed by City Manager, Steve Rymer. Councilor Shaw
stated that Steve Rymer is aware of that situation, and he is working through how they can
accommodate Fridays.
Darren Black mentioned he is available to answer questions regarding billing in Tyler. He is
making sure bills are accurate, making sure each one of the rates are being applied as they
should be and that the bills are matching as they should. Chair Walkiewicz asked if residents
would need to set up a new account. Torri Porter stated they will have to set up a new
account for the new portal, but they will keep the same account number. If they are currently
set up for autopay, they will need to sign up for that again in the new system.
3. Water Supply Updates
Brian Rager briefly went over the February and March supply updates, and noted the report
was typical for this time of year. Councilor Shaw noted that usage has gone up in the last
couple of months, is it showing a possible trend. Mr. Rager stated this could be due to
population growth and less rainfall. Chair Walkiewicz stated that it is too early to label this as
a trend. Mr. Rager stated he would check into this and get back to the WAB with his
findings. Chair Walkiewicz mentioned the WAB might want to go on the tour with the
Clackamas River Water Providers. She found this extremely helpful. Councilor Shaw
suggested that this could be set up to include the entire board. Mr. Rager agreed and will
watch for the opportunity when announced by the Clackamas River Water Providers.

4. Proposed Water CIP
Joe Wisniewski discussed the Capital Improvement Plan budget projects for the next 6 years.
The FY25 outlook for projects shows what he believes can reasonably be accomplished.
Total cost for CIP projects is 280 million dollars, which includes all the projects in the
Water, Parks, Transportation, Facilities, Stormwater and Sanitary Sewer systems. The water
portion of the 6-year CIP is a total of 55.8 million dollars, and of that is a proposed amount
of 20 million dollars in FY25. It is a significant amount of work, but there are some very
large projects underway and coming up in FY25.
Some of the projects to highlight that are underway or funded for next fiscal year is the
completion of Reservoir 18 and Pump Station. This is to help with a lot of the growth in the
Bull Mountain area. The Engineering team is also starting the planning of reservoir 19,
which will serve the lower elevation portions of the southern side of Bull Mountain and the
expansion areas of River Terrace, as well as Kingston Terrace, which is within the King City
urban growth boundary expansion. For FY25, the focus will be to complete a siting and
feasibility study. The land purchase is budgeted, so once an ideal site is found, the purchase
can be made. The team will also watch for any opportunity where they can coordinate with a
land developer for the siting of the reservoir. Mr. Brewin asked if it would be an above
ground tank. Mr. Wisniewski stated the city prefers tanks to be at or below grade, seismic
requirements must be addressed regardless. Mr. Brewin asked instead of purchasing land, is
it feasible to put it in this unused park plan at Roy Rogers. Mr. Wisniewski stated the
elevation there is substantially lower than where the tank would have to be sited. The tanks
must be sited within the pressure zone range that it will serve. This tank will require an
elevation of between 380-410 feet. There is a significant elevation change there. The ideal
elevation band is near Orchard Park and some of the developed area off of 150th and it kind
of follows just behind the Art Rutkin school. The team is looking for approximately 2-5
acres to site the reservoir.
Mr. Wisniewski then talked about system plan addendums. The last water system plan was
adopted in 2020. With all the urban growth boundary expansions the city must complete
addendums to the system plan to address those areas. The addendum for Kingston Terrace
is under way, the King City site. The next addendum will address River Terrace 2.0. That
addendum will show the true needs of the system to serve that area. It will include a
financing plan, the System Development Charges (SDCs), the reservoir sizing, demand on
Water Advisory Board (WAB) Minutes
SERVING TIGARD WATER SERVICE AREA
Page 5 of 8
the treatment plant, and the role that aquifer storage and recovery (ASR) wells might play in
serving the area. The addendum should be complete by the end of FY25.
Mr. Wisniewski next talked about the Water Treatment Plant and the Raw Water Intake
Pump Station (RIPS) Generator project. He referenced the ice storm that took place a few
years ago, where power was lost at both facilities. This project will provide emergency
backup power. Lake Oswego is leading that project; Tigard is a partner through our IGA,
this is basically the funding for our ownership for that project. The ideal solution is a “plug
and play” where a portable generator can be deployed when needed. Lake Oswego is
looking at vendors that would be supplying the generator. Mr. Henschel asked if they have
looked at the PGE program, they have a fleet of 93 generators around the area that can be
deployed. Mr. Brewin asked if the backup is rechargeable, and if so, how is it charged. He
also asked if a solar array could charge it. Mr. Wisniewski stated they are still in design and
penciling out the ideal set up. The generators are mobile so they will likely be diesel-
powered. For the size of generator needed, solar would not be an option.
The next project discussed was the Water System Service Line Inventory, which is a
requirement of the Lead and Copper Rule revisions. The inventory work is almost finished.
If desired, Project Manager Ross Horton can provide a final wrap-up report to the WAB.
Mr. Brewin asked about the Rotary Plaza restroom project and, how many restrooms are
impacted by the project. Mr. Wisniewski stated there is just one restroom behind the coffee
shop. This project will address a problem where the city maintenance crews have to clean
the line multiple times per month. Mr. Brewin asked why the project will cost $360,000. Mr.
Wisniewski explained some details of the project and that it is also expensive to send the
sewer cleaning truck out so frequently to address the issue.
5. Proposed Water Operations Budget
Brian Rager discussed the Public Works water operations budget starting with an overview.
He discussed what the key accomplishments were for FY24 and the key investments and
goals for upcoming FY25. He briefly discussed some division overhead budgets, and big-
ticket items. Councilor Shaw asked if the personal services section included the FTEs for
vacant positions. Mr. Rager confirmed it does. Mr. Brewin asked how much of the total is
for benefits. Mr. Rager stated it is about 30%, which is all calculated by the finance
Department.
Water Advisory Board (WAB) Minutes
SERVING TIGARD WATER SERVICE AREA
Page 6 of 8
Mr. Rager went over water costs, which are based on anticipated usage and what the city will
pay to Lake Oswego. These costs are covered by the water rates.
Professional/Contractual budget costs. This line item is used to pay for consultants. It is also
used to pay for water testing, which is outsourced to another company. The Repair and
Maintenance line item is for water meters and replacement of water meters. Electricity, PGE
continues to raise rates, so we have to keep raising our costs. Mr. Henschel asked what
happen with the fire hydrant replacement every year, it seems to have stopped. Mr. Rager
stated there are some best management practices that are not being met right now, mostly
due to a few vacancies. We are not showing an increase in FTEs currently.
Special department expenses include franchise fee to the city, which every utility pays for
water sales within city limits. This also includes the rebates to King City, Durham, and
Tigard Water District for respective sales in those boundaries.
Indirect charges for overhead budgets. Every division has to pay certain percentages for
other services in the city. Finance is making some adjustments to the algorithm that
calculates these. Councilor Shaw asked Mr. Rager to confirm if the utilities were paying a
disproportionate share of the overhead costs. Mr. Rager confirmed that there were some
issues, one of which was in the Streets Division. There is a whole cost allocation plan that
finance controls which is based on a number of employees in each division. Because some of
the percentages were disproportionate in many divisions, they are working on fixing that.
Mr. Rager stated he was not sure if these were the final numbers or if things could change.
Overall, the indirect charges for water is going down 15%.
6. Approval of Minutes – December 13, 2023, and February 15, 2024
The WAB discussed the amendments for the December 13, 2023, meeting minutes which
include updating Councilor Shaw’s title. Chair Walkiewicz stated the primary changes for
December 13th minutes were to correct the meeting notes showing that Ken Henschel was
not yet an At-Large member (commissioner) of the WAB. Mr. Brewin mentioned #2 needs
to be updated to reflect Ken Henschel was not an At-Large member at that meeting. He also
mentioned #8 the adjournment portion needs to be amended to reflect Ken Henschel was
not an At-Large member at that meeting.

8. Non-Agenda Items – Review of Future Agenda Topics
Mr. Brewin asked if the backflow topic will be on the agenda for our next meeting. Mr.
Rager stated yes, we will be discussing that topic at the next meeting. Mr. Brewin asked who
the person is that will be handling that. Mr. Rager stated Hung Nguyen and Aaron Beattie
from Water. Councilor Shaw asked if the board received the State of the City invitation
which is happening on May 13, 2024, at Broadway Rose Theater at 6:00 pm. Shauna Large
will forward the email to the WAB group. Chair Walkiewicz asked Ms. Large if she had
created the potential future agenda topics spreadsheet. Ms. Large stated that she would ask
IT to set up a WAB Teams channel, which is where the spreadsheet will be saved. Chair
Walkiewicz stated she would like to see an overview of the Water Conservation Program as a
future agenda item. Chair Walkiewicz also mentioned the need to add the amounts of time
for each topic in the agenda and the meeting shouldn’t be longer than an hour and 15
minutes. Mr. Brewin mentioned the Emergency Management Plan, the water curtailment
plan in conjunction with our partners at Lake Oswego. Mr. Rager stated that the city has
that, and he will bring that to a future meeting. It is referenced as the Water management
Conservation Plan, and it was developed in partnership with Lake Oswego.

Alkalinity: 22.44 ppm
Alkalinity is water's capacity
(buffering) to resist acidic
changes in pH or to neutralize
acid. A normal range for
alkalinity in finished drinking
water is 20-200 mg/L (indicated
by the blue shaded area). The
EPA Secondary Drinking Water
Regulations limit alkalinity only
in terms of total dissolved solids
not to exceed 500ppm.
pH: 7.68
pH is a numerical measure of
the acidity or alkalinity (base) of
a solution, measured on a scale
of 0 to 14. Neutral on the scale
is 7 (indicatd by the gray line in
the chart), below 7 is acidic and
above 7 is alkaline. For drinking
water, slighly base chemistry
(alkaline) provides anti-
corrosion properties to protect
water supply plumbing and
reduces the risks associated
with lead solder and copper
plumbing.
Water Temperature: 7.69C
(46F)
While water temperature can
have a major influence on
biological activity and organic
life in bodies of water, there is
not an EPA standard for the
temperature of finished
drinking water.
As you can see in the chart
above, the temperature of the
finished drinking water
fluctuates in tandem with the
temperature of the source water
(Clackamas River).

Chlorine Residual (0.2-4.0ppm boundary)Chlorine Residual: 1.13 ppm
Chlorine is a disinfectant used to
protect the public from virus,
bacteria, and other micro-
organisms. The maximum level
for chlorine in drinking water is 4
ppm and the minimum level
required is 0.2 ppm (indicated by
the yellow shaded area in the
chart above). The average
chlorine residual from July 2020
to current is 1.10 ppm.

Alkalinity: 22.0 ppm
Alkalinity is water's capacity
(buffering) to resist acidic
changes in pH or to neutralize
acid. A normal range for
alkalinity in finished drinking
water is 20-200 mg/L (indicated
by the blue shaded area). The
EPA Secondary Drinking Water
Regulations limit alkalinity only
in terms of total dissolved solids
not to exceed 500ppm.
pH: 7.72
pH is a numerical measure of
the acidity or alkalinity (base) of
a solution, measured on a scale
of 0 to 14. Neutral on the scale
is 7 (indicatd by the gray line in
the chart), below 7 is acidic and
above 7 is alkaline. For drinking
water, slighly base chemistry
(alkaline) provides anti-
corrosion properties to protect
water supply plumbing and
reduces the risks associated
with lead solder and copper
plumbing.
Water Temperature: 8.36C
(47F)
While water temperature can
have a major influence on
biological activity and organic
life in bodies of water, there is
not an EPA standard for the
temperature of finished
drinking water.
As you can see in the chart
above, the temperature of the
finished drinking water
fluctuates in tandem with the
temperature of the source water
(Clackamas River).

USGS Clackamas River Water Data
The following charts contain U.S. Geological Survey data collected from the Clackamas River. The charts on this
page show a comparison of the current month of data to that same month in the prior years, as well as an average
over those years. On the second page, those charts show the historical trends of each metric from January 2014
to current. Turbidity, a metric not yet defined in this report, is the relative clarity of a liquid. It is an optical
characteristic, measuring the amount of light scattered by material in the water, measured in nephelometric
turbidity units (NTU).

Development of the Capital Improvement Plan (CIP) typically occurs over the first two quarters of each fiscal year as input
to the annual city budgeting process. Lists of potential projects are informed by systems plans, Council and community
feedback, sta -identified needs, as well as from prior CIPs where projects lacked su cient funds.
Priority projects align with Strategic Plan goals, solve existing system operations and maintenance issues, create needed
infrastructure to serve existing or new customer demand, and provide reliable, sustainable systems.
Prioritization of potential projects occurs as follows:
1. Sta and subject matter experts evaluate potential projects
2. Advisory Committees review confirmed projects
3. Community feedback is received during Budget Committee hearings prior to CIP recommendation to City Council for
final budget adoption
All projects shown in the city’s six-year CIP represent high priorities, where funding is or likely will be available, and
where sta project management and delivery capacity is expected. Funding sources include city fees, taxes and charges,
as well as grants and other partner organization contributions. Funding availability assumptions are based on projected
revenues and rates, and the known or anticipated likelihood of acquiring outside grants and contributions. Projects listed
early in the six-year CIP, in fiscal year 2025 in this case, have the most secure funding, while projects in out-years have
less funding assurance; lists for these out-years may be revised in future CIPs based on best available information.
Grants and partnerships are important to funding and delivering city infrastructure. Resources provided through these
programs allow the city to address high-priority needs that they are unable to fund on their own. Unfunded and prioritized
projects may be selected for future grant or partnership opportunities.
The following pages show the CIP by system. Unfunded projects, shown at the end of each system table, are listed in
priority order. Project ranking, informed by strategic priorities such as safety, equity, opportunity, and funding available,
factor into project selection. The Projected Cost column is an estimate and will be updated as resources become
available.

96030 - 560-East Pressure Zone Consolidation Project (Formerly Bull Mountain Water Pipeline)
Project Need: Due to topographic limitations of Bull Mountain and varying times of past development, the 560-foot
pressure zone (PZ) is comprised of eight independent subzones around Bull Mountain: 560A-H. A 640-foot PZ also
serves customers on the west side of Bull Mountain. With the exception of the 560G subzone, water is supplied to the
640-foot PZ and 560-foot subzones from the upper pressure zone (713-foot PZ) via pressure reducing valves (PRVs).
The PRVs require regular maintenance and specialized training in order to operate them. Therefore, the 2020 Water
System Plan (WSP) recommended consolidating these subzones as much as possible. Additionally, the 2020 WSP also
identified a firefighting water deficiency in the 530-foot PZ and poor condition of Reservoirs 1-1 and 1-2.
Project Description: To improve water system operation and resiliency, portions of pressure zones will be
consolidated into a new 560-East Pressure Zone. Work will include installation of new piping on Bull Mountain Road
and across SW Pacific Highway to connect the different pressure zones. The project will also abandon Pump Station 1,
prepare a site plan for replacement of Reservoirs 1-1 and 1-2, and isolate obsolete equipment at Water Site 2.
Operations and Maintenance Impact: Minor increase in operations costs for new water line.
Prioritization: System Enhancement or Regulatory Requirement

96040 - Reservoir 18 and Pump Station
Project Need: System improvements are required to address storage and pumping deficiencies identified in the River
Terrace Water System Plan Addendum that was completed in conjunction with the planning for the development of
River Terrace 1.0.
Project Description: The project is for the design of a new water reservoir, associated new water lines, and
replacement of a temporary pump station for the city's 560-foot service area. The reservoir will be constructed on city-
owned Sunrise Park on the west side of Bull Mountain. A new permanent pump station will replace an existing
temporary pump station on the Reservoir 13 site to move water from the 410-foot to both the 560- and 713-foot
service areas. The project will provide additional storage and pumping facilities to address system deficiencies and
development demand in River Terrace.
Operations and Maintenance Impact: Significant increase in operation and maintenance for new reservoir and pump
station.

96046 - Red Rock Creek Waterline Relocation
Project Need: This project will be constructed after the Wall Street / Tech Center Drive connection project and will
provide domestic and fire services to properties served by the existing waterline currently located in Red Rock Creek.
Project Description: Abandon the existing 12-inch waterline running parallel to Red Rock Creek in place and connect
the dead-end waterlines in Wall Street and Tech Center Drive to create a system loop. In doing so, this will delete a
waterline railroad crossing.
Operations and Maintenance Impact: None.

96053 - Aquifer Storage and Recovery Well #2 and Well #3
Project Need: The Water System Plan has identified the need to expand the city’s Aquifer Storage and Recovery
program to meet its long-term water demands.
Project Description: The city’s Aquifer Storage and Recovery (ASR) program began in 2001 with the drilling of ASR 1.
In 2006, the city completed the construction of the ASR 2 facility and in 2007 the city drilled and tested ASR 3. This
project has three phases: (1) construction of new facilities to make ASR Well 3 operational; (2) replacement of electrical
devices with easier-to-maintain components in existing ASR 2 facilities; and (3) connection of two pressure zones to
improve storage and distribution from ASR 3.
Operations and Maintenance Impact: Operations staff will be able to manage summer peak demands more
efficiently in the future.

96058 - Pipeline Renewal and Replacement Program (PRRP)
Project Need: The city’s water distribution system is comprised of approximately 276 miles of pipe, of which
approximately 25 percent is cast iron that can be at risk of leaks and breaks. The city has established the Pipeline
Renewal and Replacement Program (PRRP) because failure to proactively replace aging pipe can have catastrophic
financial implications. The 2020 Water System Plan recommended that the city address all distribution system pipes
within a 100-year timeframe.
Project Description: The PRRP was established in 2022. A desktop risk analysis of the water distribution system was
completed in 2023, identifying pipes with the highest breakage risk. The PRRP is also employing acoustic leak
detection to further refine the water distribution system risk assessment. In 2024, the PRRP will replace approximately
one mile of pipe. In 2025 and 2026, approximately two miles of pipe will be replaced annually. By 2027, it is anticipated
that the city will have built up the resources and efficiencies needed to replace approximately three miles of pipe per
year. At times, funds may be transferred from this program to individual capital projects to leverage opportunities to
replace water lines within other projects such as major street improvements.
Operations and Maintenance Impact: Increase in impact during annual construction activities; however, the program
will result in a net decrease in impact as older, leak-prone water lines are replaced.

96060 - Generator Replacement at Pump Station 1
Project Need: The current generator is approximately 35 years old. Because of its age, replacement parts are hard to
find, and maintenance costs are increasing. Additionally, a structural evaluation of the building in which the generator
is housed determined the building is not seismically resilient and likely to experience significant damage in the event
of an earthquake, likely rendering the generator useless. Aquifer Storage and Recovery Well #1 (ASR-1) is a critical
emergency source of drinking water and co-located with Pump Station 1. The current generator is not properly sized
to operate both ASR-1 and Pump Station 1. Electrical equipment needed to operate Pump Station 1 and ASR-1 is
approximately 50 years old and past its useful life.
Project Description: Critical electrical equipment will be replaced and moved to a new seismically-resilient location
adjacent to the ASR-1 wellhouse, including switchgear, automatic transfer switch, and generator. This will enhance
reliability and ensure this critical equipment is able to operate in case of emergency.
Operations and Maintenance Impact: Enhanced reliability and stability should reduce maintenance cost over time.

96063 - Pressure Zone Consolidation - Zones 560C and D
Project Need: Due to topographic limitations of Bull Mountain and varying times of past development, the 560-foot
pressure zone (PZ) is comprised of eight independent subzones: 560A-H. Water is supplied to these subzones from
the upper pressure zone (713-foot PZ) via pressure reducing valves (PRVs). The PRVs require regular maintenance and
specialized training in order to operate them. Therefore, the 2020 Water System Plan recommended consolidating
these subzones as much as possible.
Project Description: In order to connect the 560C and D subzones, the following work must be performed: demolish
the existing PRV at Greenfield Drive and SW 132nd Avenue and install a new PRV at Greenfield Drive and Benchview
Terrace (to provide fire flow, if modeling indicates it is necessary), install necessary piping connections to connect the
subzones, and demolish the historic pump station on SW 132nd Avenue.
Operations and Maintenance Impact: Expect some reduction in time and cost of system operations and
maintenance.

96064 - Reservoir 8-1 Structural Improvements
Project Need: In fall of 2020, exposed rebar was noted in multiple areas of the roof of Reservoir 8-1. A structural
condition assessment of the roof was immediately completed. The assessment determined that while roof failure is
not thought to be imminent, the roof itself is nearing the end of its usable life as cracks were noted along the
reinforcing grid spacing (i.e., structural rebar) on both the roof exterior as well as the roof interior. Cracks and
efflorescence on the roof interior indicate that the intrusion of external water is occurring, which poses a potential
contamination risk. Cracks were also noted along the interior roof beams, which may indicate potential overstresses in
the beams. A waterproofing epoxy coating will be applied to the roof exterior in the near term to prevent further
water seepage; however, further structural analysis and improvements must be considered to address the sagging of
the roof and cracking in the beams.
Project Description: A structural analysis will first be performed to determine the best course of action to address the
sagging roof and cracked beams. Following the analysis and design, construction activities will occur. Construction can
only be started once Reservoir 18 is complete and must be completed within one Fiscal Year as Reservoir 8-1 cannot
be offline during the peak summer season.
Operations and Maintenance Impact: Slight impact during construction activities in fiscal year 2026 as the reservoir
will be offline, but none once the reservoir is back in service.

96065 - Water Meter Modernization
Project Need: The Tigard Water Service Area (TWSA) water meters require city staff to physically visit each to record
water usage. The existing water meters in Tigard are often beyond their expected lifespan and no longer record water
usage with sufficient accuracy. New water meter technology allows for more transparent and accurate water meter
readings, benefiting both the city and the customer. Implementing this project will increase customer service and
assist with leak detection reporting to reduce the waste of treated water and property damage resulting from leaks.
Project Description: The Water Meter Modernization Project will replace existing meters across the TWSA with new
meters that communicate electronically with Public Works and Utility Billing departments, streamlining the meter
reading process and allowing automated alerts to staff for potential meter issues or water leaks. The project will be
completed in phases. Phase one will include a pilot project with a small number of advanced water meters and a
thorough evaluation of available water meter technologies. An implementation plan will then be created based in part
on the results of the pilot project. Phase two will involve installing meters, radios, and communication equipment
across the TWSA.
Operations and Maintenance Impact: The impact is unknown at this time. Engineering and Operations staff are
currently undertaking a pilot project to understand better the full-scale project delivery method and resources
required to construct and operate the project. Depending on the pilot project recommendations, there could be
significant impacts on the operations and utility billing staff.

96067 - Water System Service Line Inventory
Project Need: The city is required to create an inventory of all water meter service lines in the Tigard Water Service
Area (TWSA) per the Environmental Protection Agency (EPA) Lead and Copper Rule Revisions (LCRR). The LCRR
were adopted in late 2021, and thus not addressed in the 2020 Water System Plan. This inventory must identify the
pipe material type of all water service lines in the TWSA, on both the public and private sides of the water meter.
The inventory is required to be submitted to the Oregon Health Authority (OHA) by October 2024 and updated
annually. If any service lines materials are unknown as of October 2024 or identified as being made of lead, a
service line replacement plan must be submitted to OHA for approval and then implemented.
Project Description: This project will create the inventory required by the LCRR and ensure compliance with EPA
and OHA regulations. The inventory creation will include review of historical records and physical investigations of
service lines connected to TWSA water meters. The project will also prepare the service line replacement plan as
necessary. All required documentation will be submitted to OHA by the October 2024 deadline.
Operations and Maintenance Impact: Physical investigations of water service lines will utilize Tigard water
maintenance crews to complete the work, temporarily increasing their workload during the physical investigation
period. Ongoing minor increase in operations staff workload to maintain and update the LCRR inventory.

96069 - Pump Station 8 Rebuild
Project Need: The 2020 Water System Plan identified Pump Station 8 as being near the end of its usable life and
Reservoir 8-3 for abandonment due to its age and limited storage capacity. In addition, Pump Station 8 is currently
split between two sites, which is abnormal: two pumps are on the north site with Reservoir 8-3 and three pumps are
located on the south site with the remaining Reservoirs 8-1 and 8-2. It was also determined that rebuilding Pump
Station 8 on the north site would be the best use of the property and advantageous for operations and maintenance
staff as all pumps would be co-located in one pump station.
Project Description: Reservoir 8-3 will be demolished and a new Pump Station 8 will be built on the north site. The
existing pump station vaults on the north and south sides will be properly demolished as well. This project cannot be
completed until the Reservoir 8-1 Structural Improvements (CIP #96064) has been completed, which in turn cannot
begin until Reservoir 18 (CIP #96040) is fully online.
Operations and Maintenance Impact: Slight decrease once Reservoir 8-3 is demolished. New pump station should
not impact operations and maintenance as same pumping capacity will be replaced.
Prioritization: System Enhancement or Regulatory Requirement

96070 - ASR Expansion Feasibility Study
Project Need: Under the city’s aquifer storage and recovery (ASR) limited license, the city has the ability to drill and
install up to five ASR wells. Three ASR wells have been drilled since the limited license was obtained in 2000 and serve
as the city’s back-up resilient water source. With anticipated population growth and increasing water demand, the city
will will optimize operation of its existing ASR wells to meet increased water demand and evaluate if the development
of additional ASR wells is feasible.
Project Description: The first phase of this project will utilize the City’s hydrogeologist of record to perform an
evaluation of current ASR well operations and to prepare a new operational plan to meet projected increased water
demands. In the second phase of this project, the City’s hydrogeologist of record will assist staff in locating potential
sites for additional ASR wells. In addition, test wells will be drilled by a qualified driller in order for the hydrogeologist
to determine suitability of the well for ASR purposes. Therefore, the second phase study will include both consultant
and drilling services.
Operations and Maintenance Impact: None.

96071 - Water Management and Conservation Plan
Project Need: The purpose of a Water Management and Conservation Plan (WMCP) is to serve as a guide for the
development and implementation of programs and policies to ensure sustainable use of water resources in the city.
The WMCP will provide a description of the water system, identify the water source(s) used, and explain how the city
will manage and conserve supplies to meet future demands.
Project Description: Prepare a WMCP that evaluates the management and conservation measures that the city can
undertake. The WMCP must consider water that can be saved through conservation practices as a source of supply to
meet growing demands if the water saved is less expensive than developing a new supply. The plan represents an
integrated resource management approach to securing the city’s long-term water supply.
Operations and Maintenance Impact: None.

96072 - Water System Plan
Project Need: The city conducts water system planning every five to ten years. The current Water System Plan was
adopted in December 2020. The 2020 Water System Plan identified a piping seismic backbone that would be used to
move water throughout the city if a major seismic event were to occur. A fifty-year water distribution system seismic
plan will develop a strategy for seismically hardening that backbone.
Project Description: The Water System Plan is a comprehensive study of the city’s water source as well as storage
and delivery systems and will be used to guide future water utility discussions. Develop a plan for seismically
hardening the backbone identified in the 2020 Water System Plan. The plan should also include further seismic
analyses of Pump Station 5 and Reservoir 13 and develop a fifty-year capital improvement plan. The Water System
Plan has a 20-year planning horizon and is predicated on the city’s projected population growth during that time.
Operations and Maintenance Impact: None.

96075 - Lake Oswego / Tigard Water Supply Extension
Project Need: The 2020 Water System Plan projected that as population increases, Tigard’s current supply allotment
from the Lake Oswego/Tigard (LOT) water partnership of 14 million gallons per day (MGD) will not be adequate to
continue to supply firm capacity to meet projected maximum daily demand (MDD) by 2029. Therefore, system
improvements must be complete and fully online by 2029 in order to continue to provide uninterrupted service to
customers.
Project Description: System improvements are needed to alleviate hydraulic restraints in the system in order to
increase the LOT supply from 14 MGD to 18 MGD. Work will include adding a finished water pump at the LOT water
treatment plant (cost share with Lake Oswego), installation of approximately 5,600 linear feet of 36-inch diameter pipe
from Waluga Reservoir to SW Bangy Road, installation of the sixth pump at Pump Station 5, and installation of
approximately 250 linear feet of 24-inch diameter pipe to cross under Fanno Creek.
Operations and Maintenance Impact: Minor increase in operational costs to maintain new pump at Pump Station 5.

96076 - Reservoir 19
Project Need: The 2020 Water System Plan identified the need for a new reservoir in the 410-pressure zone to serve
the growing southwestern portion of the water system and allow for aging reservoir infrastructure to be
decommissioned. In addition, the Water System Plan Addendum that is currently being completed for the Kingston
Terrace expansion area has indicated that the new reservoir must be constructed by 2029 to meet current
development timelines.
Project Description: The first part of this project includes a Siting Feasibility Study and Land Acquisition for the
proposed Reservoir 19. Due to the rapid development occurring in the 410 pressure zone elevation, the available
property for a reservoir is limited. The goal for this project is to acquire property for the reservoir prior to residential
development occurring which would cause displacement in the future if the acquisition phase were delayed. The
project scope will be adjusted to include Reservoir Design and Construction in later years.
Operations and Maintenance Impact: Minor impact for maintenance.
