water conservation efforts.
The 2009 Water Conservation Report was distributed to the Board. Mr. Goodrich noted that
unaccounted for water is at four percent, well under the industry standard of ten to fifteen
percent.
The upgrading of meters throughout the water service area and replacement of outdated water
lines in King City was discussed.

5. Proposed City of Tigard Water Capital Improvement Plan (CIP) Budget
The following documents were distributed to the Board:
1. Capital Improvement Plan —Water
2. Water Budget
3. Comparison of 2000 vs. 2011 Budget
Mr. Koellermeier discussed the Capital Improvement Plan and the projects contained in the
plan. The Tigard Budget Committee has approved the budget and the budget is on its way to
the Council for final adoption. The Budget Committee needs to approve a technical adjustment
related to the Sherwood Water Partnership on Monday. The adjustment means $1 million will be
reallocated from this fiscal year budget to next year's fiscal year budget.
Mr. Koellermeier relayed the highlights of the Comparison of 2000 vs. 2011 Budget document.
He noted staffing had decreased while the number of customers increased. The materials and
supplies have increased which means we are investing these dollars back into the system. The
cost of water has remained stable with only a 4.34 percent average increase per year over that
time period.
Commissioner Winn expressed concern that the Board did not have sufficient time to review the
Water Capital Improvement Plan. Mr. Koellermeier suggested the Commissioners send any
comments to him.
6. Sherwood Water Partnership, Pipeline from Wilsonville Water Treatment Plant
Mr. Koellermeier reported that there has been a change on the partnership agreement that is
coming to the Board. Sherwood has already bid out this project and is under construction. The
bids were very good in this financial climate and the project has seen substantial cost savings.
Tualatin has decided not to participate in the project, which gives Tigard access to more water.
Sherwood inquired if Tigard want to stay in at 10 million gallons per day (mgd) or buy up to 20
mgd capacity. The agreement is for 10 mgd: however, we will need 20 mgd. Tigard will commit
to buy 20 mgd of capacity. Tigard is currently cash poor so we will buy it over time as we sell
bonds.
Sherwood believes the pipeline will cost around $8.8 million including easements, construction
management, etc. The proposal for Tigard would be around $4.4 million to own half of the 40
mgd pipe capacity. Mr. Koellermeier recommends we go ahead with this. The pipe currently
terminates at the pedestrian bridge in Tualatin Community Park.
Mr. Koellermeier will have a legal written opinion with limits of law regarding the Tigard Charter
Amendment going to the Willamette River. Commissioner Winn expressed concern over the
requirement of taxpayers having to pay for this without a vote since it would entail taking water
from the Willamette River.
Commissioner Stone clarified that this 20 mgd Tigard portion is the most water that could be
bought from this pipeline. Parallel lines could be installed if more water was required in the
future.
Aside from Commissioner Winn's legal concerns, the Board expressed general support for the
project. Commissioner Stone stated it is inexpensive future planning and we could sell the water
if it was not needed.

Mr. Koellermeier will bring this back to the Board before bringing it before Council. It will be July
or August before the legal opinion is done and agreements are refined.
7. Water Supply Update
• Mr. Goodrich reported that water demand is currently 4 mgd.
• There is 219 mg in ASR storage, which is 102 days of supply. This should be adequate
for the peak period. ASR will be shut off at the end of May when we move from winter
interruptible supply.
• Tigard is purchasing .5 mg a day extra to get through July and August from the Portland
Water Bureau. This is the maximum amount that can flow through the system. Tigard
will pay the summer interruptible rate for all the water brought in as per the agreement,
which is at 66 percent cost.
• The Portland Water Bureau does not anticipate any water curtailment.
• There is a temporary pump station being built on 125th Avenue & Bull Mountain Road to
help supply the 710-foot zone during the summer while work is being done on 125`h
Avenue.
8. Informational Items
Commissioner Buehner reported on the selection of Red Oak Consulting to conduct the Water
Rate Study and Water System Development Charges Update. Council approved the contract
last night.
a. Update from Commissioner Buehner on Lake Oswego/City of Tigard Oversight
Committee activities
• A handout entitled Lake Oswego Water Treatment Plant Alternatives Study was
distributed to the Board. Commissioner Buehner summarized the handout and
different treatment options. The circles on the handout are transposed in the last
column for alternatives 2.1 and 2.2. Membrane proposals (the "3" options) were
removed from consideration. They take less oversight, but are more expensive. The
treatment options range from $65 million to $121 million. Alternative 2.2 is close to
the Wilsonville treatment plant. The Wilsonville treatment plant is the gold standard
for this area.
• The Joint Water Supply source water (Clackamas River) does not require the level of
treatment Wilsonville did for the Willamette River. These treatment plant options are
being considered for the future in case regulations change since more regulations
are anticipated. If the treatment plant only treated the water to high rate
sedimentation, it would meet drinking water standards. The questions providers have
to ask are:
o What is the level of service they want to provide to the customers?
o What level quality of water do you want to deliver?
o How certain do you want to be to meet future drinking water standards?
• Mr. Koellermeier stated the process of picking treatment method will be concluded in
June. Meetings are open to the public. A presentation of how this all came together
will be made at the joint IWB and City Council meeting.
• Citizens seem to be most concerned with taste and odor issues.
Commissioner Fowler left the meeting at 6:45 p.m.

b. Update from Commissioner Winn on West Bull Mountain Technical Advisory
Committee Activities
• Commissioner Winn reported the committee is undergoing revisions to
accommodate several requests for change.
c. Updated from Commissioner Henschel on the Citizen Sounding Board activities
• Commissioner Henschel did not attend the meeting so there was no information
reported.
d. Water Treatment Plant Informational Tour— Mr. Goodrich will circulate dates and
preferable times. It was suggested that they meet at the West End Building.
9. Non-Agenda Items
Mr. Goodrich and Mr. Koellermeier are working on a public open house on June 24 at the West
End Building 5:00 or 5:30. The invitation will be in the Consumer Confidence Report (CCR)
which goes to all our customers and consumers. The purpose of this open house is to educate
the public on all the work that citizens and the expert panel have done and which treatment
options are going to be chosen. This is the first public hearing of the treatment plant decision
process.
Commissioner Buehner stated Ms. Newcomb, head of Citizens for Safe Water group, was at the
Willamette River Water Coalition (WRWC) meeting, she raised concerns about the ozone and
Granular Activated Carbon (GAC) treatment process.
Mr. Goodrich stated Red Oak Consulting will be at the June 15 joint Tigard Council/IWB meeting
giving a 30-minute overview of water rate SDC so we can bring everyone up to speed.
10. Future Agenda Items
• Future agenda items were not discussed.

5. Water System Master Plan Presentation
Mr. Koellermeier introduced Senior Project Engineer Rob Murchison. Mr. Murchison introduced
the Corollo Engineering team, Nikki Pozos and Dave Kraska. After the IWB presentation, the
Water System Master Plan will go to the Tigard City Council for adoption. The Powerpoint is on
file in the IWB record.
Some information clarified during the presentation is as follows:
• The volume in ASR 3 is 2 to 2.5 million gallons per day recovery.
• Tigard has terminated the partnership agreement with the Joint Water Commission and
are now a wholesale customer able to purchase water if needed.
• The Corollo report is at the 50th percentile, the average projection or the midpoint; this is
not a worst-case or drought year scenario projection. Tigard would implement mandated
curtailment activities for severe climatic change. The City has two days of storage for
emergency use with the current reservoirs at average daily demand; this does not
include the future Cash Reservoir.
• The report incorporated stepped up conservation. Corollo examined prior year's per
capita usage and noticed a big reduction.
• Corollo did not take into account the additional 6 mgd from the Lake Oswego-Tigard
Water Partnership expansion because we are not under contractual obligation. If we
could acquire the additional 6 mgd, it would take us to 2040.
• Many of the older pump stations could be taken out of service because the older pump
stations are low capacity. The network of piping could be designed to have a lot of little
pump stations lifting the water from one to the next or replace little pump stations with
one reliable, modern designed station that is accessible at ground level and does not
have confined space entry and maintenance issues.
• The new pump stations are built to have a high level of reliability and redundancies so
there is still enough capacity if one pump went out. Maintaining old pump stations is a
major maintenance hassle and the capacity is so much smaller than what is needed.
• Hi Tor pump station capacity is good, however it does not have great reliability nor is it in
the best condition. It will be one of the last ones replaced.
• There are not a lot of pipes in poor condition that need replacing now. Properly installed
cast iron ductile pipes will last a long time and the Tigard area pipes are made of ductile
iron. Pipes that have problems are made of pvc or asbestos. As redevelopment happens
(i.e., Burnham and Main Streets), older pipes will be replaced.
• Security is addressed while doing projects. For instance, when existing reservoir
projects are proposed, all hatches are retrofitted for greater security including alarms;
and reservoirs are closely evaluated for other security measures, such as air vents.
• The telemetry system was updated in 2005-06. It is a dedicated, wireless radio. When
new sites are built, they are connected to this telemetry system.
• Tigard has water pipes under Bull Mountain Rd; however, COT does not have the $2
million to complete the improvement shown in the Master Plan. Washington County is
paving the road starting Monday. This is the most likely route of the pipeline. COT is
looking at alternative routes to avoid that route since it will be two to three years before
we can build the pipeline.
• A seismic evaluation was completed four years ago. COT does not have enough money
to do all the seismic upgrades. When we are working on a reservoir, we do a seismic
Intergovernmental Water Board Minutes April 14,2010
2
evaluation and figure out its vulnerabilities as part of the project. We did a vulnerability
assessment that identified the most critical facilities; this is where we will spend our
money first.
Mr. Murchison, Ms. Pozos, and Mr. Kraska David departed at 7:00 pm.
6. Proposed City of Tigard Water Capital Improvement Plan (CIP) Budget
Mr. Koellermeier said the CIP budget had not been completed by the City's finance department.
7. Water Supply Update
• Mr. Goodrich reported that water demand is currently 4.3 to 4.5 million gallons per day
(mgd). COT is still injecting into Aquifer Storage and Recovery (ASR) 1. This will be
completed by June 3. The goal is to reach 120 million gallons in storage.
• COT is contracting an additional .5 mgd from Portland Water Bureau (PWB) at a
summer interruptible water supply. This water will be sold to us at about 66% of
wholesale cost for the 60-day period from July through August. This is the maximum
capacity we have in our pipeline from PWB.
8. Process of How to Amend/Transfer Groundwater Registration Modification
Mr. Goodrich reported that the minor changes requested by TWD were accomplished. Staff
requests Member's sign the modification to get it to the Oregon Water Resources Department
(OWRD) by the April 25th deadline.
9. Informational Items
a. Update from Commissioner Buehner on Lake Oswego/City of Tigard Oversight
Committee activities
• Commissioner Buehner reported that the oversight committee survey results
commissioned by the public outreach program came back positive as far as
attitudes, water supply quality, understanding of where their water comes from, what
was known about the new project, if they knew their water rates were increasing, etc.
Our citizens are more informed than citizens in other areas, think the water system is
great, and understand what is going on. However, there was not a lot of support for
higher rates.
• They have been interviewing applicants to do the water rate study and system
development charge update to determine how to finance improvements for the Lake
Oswego plant. The committee recommended two firms to go to the next level of
interviews on April 20th. The consultant will be hired shortly thereafter. The new rates
need to be in place by Jan 2011.
b. Update from Commissioner Winn on West Bull Mountain Technical Advisory
Committee Activities
• Commissioner Winn reported the focus was on transportation this month. There was
not any discussion related to water.
10. Non-Agenda Items
• Commissioner Winn would like Mr. Goodrich to schedule another tour of the Lake
Oswego water treatment plant for the IWB, TWD, and anyone else who would like to be
included.
• COT will distribute an updated IWB roster once the new Durham representative is
appointed.
Intergovernmental Water Board Minutes April 14,2010

• Commissioner Henschel would like to be added to the IWB agenda to give updates
regarding the citizen sounding board.
• Mr. Koellermeier stated there are several boards with a lot of information. He suggested
we deal with them all from a technology standpoint. COT can email or create a website
for projects schedules, information, etc.
• Commissioner Winn would like the IWB to pay attention to the Robert's Rules of Order-
no side conversations.
• Commissioner Buehner announced that when COT gets the new rate study on board,
they would give a joint presentation to IWB, Tigard City Council, and Lake Oswego City
Council on June 15. She invited the TWD board members to listen to the presentation.
• Ms. Gaston stated that May 12 is the next IWB meeting. The regular June meeting has
been cancelled so the IWB can attend the June 15 meeting with the councils.
• Commissioner Henschel inquired about the status of the IGA. Commissioner Winn
informed the Board that COT has sent it to legal. Durham and King City are waiting until
COT does their legal review. Commissioner Henschel says TWD will begin reviewing at
their board level and may take to legal before COT finishes their legal review.
Commissioner Buehner would like to know when the attorneys will get it back. Mr.
Koellermeier will inquire and let the IWB know.
11. Future Agenda Items
• Future agenda items were not discussed.

EXECUTIVE SUMMARY
The Tigard Water Service Area includes the Cities of Durham and King City,a majority of the
City of Tigard and the Tigard Water District. The Public Works Water Division provides
drinking water to an estimated 57,658 people through 17,878 residential,commercial and
industrial service connections as of December 31, 2009.
This report will discuss some of these conservation measures as well as determine the gallons
per capita per day (gpcd) for the Tigard Water Service Area. Summary conclusions for the
2009 Water Conservation Report:
• Water sold for calendar year 2009 was 2,051 million gallons (MG) or 5.6 million
gallons per day (mgd) - (Table 1).
• Within the last 5 years,peak total water use was in calendar 2007 (2,114 MG or 5.8
mgd) —(Table 1). Purchased water(total production) for calendar 2009 was 2,134 MG
or 5.8 mgd—(Table 7).
• The difference between purchased water(production) and sold water (revenue) for
2009 was approximately 4%unaccounted or non-revenue water. Acceptable industry
standard is 10-15%non-revenue water.
• Population within the service area has increased 3.9% since 2005 (Table 8).
• Total water use steadily increased by 3.2% from 2005 to 2007 (2,049 MG in 2005;
2,114 MG in 2007) (Table 1);
• Then decreased by 5.3%in 2008 (2,002 MG in 2008),and has increased again by 2.4%
(2,051 MG in 2009) (Table 1).
• Comparing data from 2005 to 2009 indicates water use in at the 2005 usage. (fable 1).
• Average GPCD water use has increased 2.4%in the last 12 months (Table 1).
• Average water use for residential and multi-residential customers is approximately 80
gpcd (Table 6—Residential and Multiple Family units only).
• Average total water use (water revenue and non-revenue water) for the TWSA in 2009
is 105 GPCD (Table 8).
• Commercial water usage has decreased by approximately 8.7% since 2005 (Table 5).
• Industrial water usage has decreased by approximately 53.3% since 2005 (Table 5).
• Irrigation water use has decreased by approximately 20.5% since 2005 (Table 5).
• Single unit water usage has decreased approximately 3.2%since 2005 (Table 5).
• Multi-unit residence water usage has increased 2.7%since 2005 (Table 5).
• Single unit and Multi-unit residence water usage decreased approximately 3.6% since
2005,and increased 3.8%in the last 12 months (Table 6).
• Water consumption data over the last 5 years indicate a downturn in the economic
conditions within the TWSA starting in 2007; 2009 data support indications of an
improved economic condition.

Introduction
The Tigard Water Service Area includes the Cities of Durham and King City,a majority of the
City of Tigard and the Tigard Water District.The Public Works Water Division provides
drinking water to approximately 57,658 people through 17,878 residential,commercial and
industrial service connections as of December 31,2009.
Water conservation has historically been viewed as a temporary solution in times of drought
or other times when emergency water storage is necessary. It has not been until recently water
utilities are using conservation as a practical long-term option in which they are able to
downsize proposed infrastructure and save on operating costs. Common goals for
conservation programs include reducing water waste,optimizing system capacity,limiting
customer costs,and minimising environmental burdens associated with both water supply and
storm water management.An important component of conservation planning is an analysis of
all measures and incentives that could be applied to reduce water demand.
Developing a water-use profile for each customer category (residential,irrigation,commercial,
and industrial) can require a significant amount of data analysis. There are two types of
residential accounts, single unit and multi-unit. Single unit residential accounts have only one
meter per unit and multi-unit residential accounts have one master meter for multiple units.
Multi-units include apartment complexes,mobile home parks, some home owners
associations and condominiums. Understanding average annual demand versus daily demand,
outdoor uses versus indoor use,determining peak flows, searching out top users and
inefficient users,and determining other characteristics of water demand can be time
consuming and prove to be a complex task. Identifying where,when and how water is used is
a critical link to determining which conservation measure will yield the most reliable water
savings.
This report will discuss some of these conservation measures as well as determine the gallons
per capita per day (gpcd) for the Tigard Water Service Area.
Data Collection
The City of Tigard's Utility Billing(UB)Division provided the Water Division with bi-
monthly statements from 2005 to 2009.Information included the consumption of water sold
(revenue) to six different types of customers,in units of 100 cubic feet(748 gallons),as well as
the number of accounts billed that month.The six types of accounts are commercial,
industrial,irrigation,hydrant meters,residential and multi-unit. For the purposes of this
report,data is broken down monthly.
Beginning in 2008,UB found a way to report each account that was read within a certain
month. Because of this new technique,it has made data collection and results more accurate.
We went back to 2004 to re-analyze the data and compared it to what we were using before.
The difference was not significant but it was enough to change the historical consumption.
This report reflects the new data collection method which we will continue to use in future
reports.
The billing cycle has proven to be a challenge when comparing water purchased (from a
wholesale provider) to water sold (consumed) for a particular time period.Accounts are billed
on different monthly cycles,therefore an overall water summary would be inaccurate because
there would be customers that have consumed water but have not yet been billed. One option
3 1 P a g e - _ ----
to lessen the effects of this calculation is to take 12 months of data starting in January when
water sales are minimal.
Water Demand
The Water Division purchases water from two water sources: the City of Portland and the
City of Lake Oswego. It also uses water from two Aquifer Storage Recovery (ASR)wells and
a groundwater well to supplement water sources during peak summer demand.With the use
of the ASR wells,large amounts of supply water are purchased and stored during the winter
months when demand and costs are low. The water is used during the peak summer months
to meet critical high demand,emergency storage for customers and emergency storage for fire
suppression. Daily monitoring is recorded along with the storage differentials. The difference
between storage water(including ASR water) and metered supply water (purchased) result in
`Water Demand' (this is the total daily production demand for revenue and non-revenue water
used or consumed).
Results
The following results summarize annual consumption in several ways. When compared to
water demand data,the water revenue data (water consumption)was summarized in years
starting in January and ending in December of that calendar year. Monthly water consumption
data was compiled into spreadsheets for the years 2005-2009. The number of accounts and
units of water per month were collected. UB reports and water revenue (consumption) per
account was calculated for each month.After all UB data was entered,each account was
summarized by year in billing units (CCF=100 cubic feet=748 gallons) and then converted
into million gallons (Table 1). Table 2 also gives the water revenue (consumption) in
percentages.

Table 1 and Table 2 indicate that single unit and multiple-unit residential customers consume
the most water in the system, 83%of total water sales,and could have the largest impact on
water demand for the Tigard Water Service Area. Commercial and industrial accounts
4 1 P a g e
consume 13%of total water sales.According to the national average,20%to 40%of billed
urban water demand is for commercial and industrial water use. A portion of the City of
Tigard commercial buildings are within the Tualatin Valley Water District,and not supplied
within the TWSA.
Although comparing totals from year to year can show a general trend,it does not take into
consideration the change in the number of accounts.Table 3 shows the percentage of growth
per account for the years 2005-2009.A negative percentage represents a loss and positive
percentage represents a gain in number of accounts from the previous year.

Annual consumption per account was calculated by adding all water consumption for the
period by the total number of accounts per year. Please note the number of accounts per year
(Table 4)is a snapshot of the service area as of December 31,2009 as reported by UB.
Consumption per type of account can be a more accurate indication of water use within the
Tigard Water Service Area.

When discussing daily residential water use,it is most often discussed in terms of gallons per
account per day (Table 5) or gallons per capita day (gpcd) (Table 6 and Table 7). Below are three
methods to calculate the gpcd value. Each method produces a different gpcd value dependant
on the variables. Using different methodologies allows for cross referencing and validation of
trending information.
5 1 P a g e
Method 1: UB Information: Total Consumption vs. Number of Overall Accounts

Single unit 216 217 218 203 209
Per person (RES) 86 87 88 81 84
In Table 5,the gallons per account per day were derived from UB revenue data.The
consumption per account was calculated from taking overall water consumption and dividing
by the total number of accounts for each year,which was then divided by 365 to get usage per
day. To find the gallons per capita per day,the single unit residential value was divided by 2.5
(the average number of people living in a single family home in Washington County based on
Portland State University Population Research Data). This information is provided to track
trends in different types of accounts,especially relating to single and multiple residential units
which would not be indicated in other methods.
Industrial account usage dropped significantly in 2006 due to a business pulling out of Tigard
and shipping their business overseas. In 2007,the consumption rose due to Clean Water
Services using an abnormal amount of water.
Method 2: UB Information and Population: Total Consumption vs. Population

Overall total gpcd 101 101 101 95 97
Gallons per capita per day (gpcd) can also be calculated using population instead of number of
accounts.Table 6 presents two different ways to calculate the gpcd using population. The
"Multi-unit&single unit gpcd"was calculated from the total consumption from both the
single and multi-unit residences which was then divided by the projected population for the
corresponding year. From this method it shows per capita use per day is 80 gallons in 2009, 3
gallons more per person per day than the previous year.The"Overall total gpcd"was
calculated from the total consumption from both the single and multi-unit residences but also
includes consumption from the commercial,industrial,irrigation,hydrant meter accounts.
This value was then divided by the population,which produces a per capita consumption per
day of 97 gallons in 2009.
6 1 P a g e
Method 3:Water Demand and Population:Water Demand vs. Population
This is the standard method recommended by the American Water Works Association
(AWWA) for calculating per capita water use. It is also the easiest method since it is a
function of total water demand (revenue and non-revenue water) divided by total estimated
population.Wholesale water data was compiled from spreadsheets that were updated daily
with the amount of water the City of Tigard purchases from each wholesaler.Table 7 displays
the monthly overall totals from the last 5 years.

The gallons per capita per day using this method is calculated from the water demand data
(Table 7) and dividing each year's water demand by estimated population (Table 8).
Production data information (Table 8) indicates the per capita use per day for 2009 was 101
gallons (Table 8);however,these calculations included both revenue and non-revenue
(unaccounted water use or loss).

Since 2005,water usage for single unit and multi-unit residential customers had been
decreasing (Graph 5 and 6). However,in 2009 we saw a substantial increase in both multi-unit
and single unit water usage. This sudden decrease and increase may have been due to the
most recent economic recession starting in 2007. Eighty three (83%) percent of all water
consumption was used by single unit (61%) and multi-unit (22%) residential customers
91Pagc
(Graph 7). Single unit and multi-unit residences could potentially save the most water per
account and lower the per capita use because they make up the majority of the water usage.

Discussion
The average per capita use can vary greatly between communities for any number of reasons
including,but not limited to:
• Climate differences
• Mix of single and multi-unit residences
• Commercial and industrial uses
• Household sizes;lot sizes;public uses
• Income brackets or local economic conditions
• Age and condition of distribution system (water losses)
According to Amy Vickers in the Handbook of Water Use and Conservation (2001) "the
combined indoor and outdoor water use in a single-family American household is estimated to
average 101 gallons per capita per day (gpcd)." In 2009,the Tigard Water Service Area single-
family household (using single unit residential account data only) had an estimated average of
84 gpcd (Table 5).
Per capita water use in multi-unit dwellings tends to be less,ranging from 45 to 70 gpcd based
on national data,because these households usually use little or no water outdoors and have
fewer fixtures and appliances. It is difficult to accurately estimate the Tigard Water Service
Area multi-unit gpcd because of the limited data available. The number of persons per unit
per multi-unit account is not known and turnover is expected but not calculated.
Conclusions
Based on the data provided in this report,the annual water demand for the Tigard Water
Service Area has increased 2 million gallons from 2005 figures,indicating a relatively flat
consumption. See Executive Summary on page 2 for further conclusions and analysis.
