5. Water Supply Update and Other Information — Dennis Koellermeier
Mr. Koellermeier referred to the handout, an excerpt from an Oregonian newspaper article,
which he found interesting in that a water district on the other side of the Portland metropolitan
area is facing somewhat the same issue as this Board—will they exist and what will their
boundaries look like. This article was provided for background information to let this Board
know it is not alone.
Current Water Supply Issues -Mr. Koellermeier reported that our supply continues to be
adequate. Depending on the day, we have 10-20 percent reserve capacity this time.of year.
Tigard Water District 1 August 28, 2006
Water Sunnliers Information—This month Portland began the process of blending(10 percent
ground water with 90 percent Bull Run water) instead of using all of the stored water and then
going 100 percent on ground water. Because some of the users complained about a different
taste and some of the commercial users had to deal with chemistry changes in the water, they
adopted the policy three years ago of starting sooner using ground water and doing a blend.
In response to questions posed by Commissioner Froude, Mr. Koellermeier commented that he
thought in the past he had shared with the Board a model predicting three possible scenarios of
how long the Bull Run stored ground water would last as compared to the weather.
Mr. Koellermeier receives a monthly update showing where City of Tigard is on the curve
(reflecting high,medium and low use) and he will include a copy in the next board packet.
The Joint Water Commission(JWC) and Lake Oswego continue to provide water to the City of
Tigard. Lake Oswego struggles a little bit on these really hot days and the city expects that to
happen and it can work around that. Most of their issues are a result of old equipment and
facilities,which have been identified and addressed in the study we are doing with them, and
need to be updated to be more reliable during hot weather.
The ASR continues to provide water for Tigard. We have probably used about 75 percent of
the water now. By the end of September, Tigard will have used all the stored water and then
the recharge period starts. The City of Tigard injects for eight months,rests for a month and
then uses for three months.
Tigard's study with Lake Oswego continues to proceed. There will be an upcoming meeting
(date is still being worked out between the Lake Oswego and City of Tigard councils). The
IWB has been invited to attend this meeting that will be held some time mid-November. When
that date is determined, Mr. Koellermeier will share that information with this board. It is an
open meeting and the Tigard Water District board is welcome to attend. The meeting will be
held in Lake Oswego. Things continue to look positive. The City of Tigard is really on the
front end of a multi-chapter study and Mr. Koellermeier has seen two of the nine chapters. The
study is due in January.
The JWC plans to publish the draft environmental impact statement in November. There will
be about a four-month study and comment period.
The JWC and the Lake Oswego material will be available at approximately the same time and
Tigard will be able to compare that to the Portland contract(three points on the decision
process so decision makers can look at all those options at relatively the same time).
Commissioner Charles Radley asked Mr. Koellermeier what is the current percentage of
fluoridation. Mr.Koellermeier responded that the City of Tigard obtains about 1.5 mgd from
the JWC starting the middle of June through the first or middle of September,depending on
flow needs. By the time you blend 1.5 to 10 mgd,it brings the percentage down to
approximately.006. The issue is,it is not a perfect blend. We don't blend it before it comes
into the city and it doesn't get distributed evenly. There are pockets that have the complete
fluoridation load and it tapers down from there. As the City of Tigard does other monthly
testing,we also test for fluoride. Those results are plotted across the city. It is an after-the-

fact concentration issue but,by modeling,the City of Tigard can over time start to tell people
that generally in August in your neighborhood you can expect this much fluoride in the water.
Commissioner Delphine asked,what is the source of this fluoride? In response,
Mr. Koellermeier stated the City of Beaverton injects fluoride in all of their water.
Commissioner Delphine then asked,where do they get that fluoride from? Mr.Koellermeier
indicated he did not know who their supplier was,but that he could acquire that information.
Most of the questions about fluoride are concerns from parents who are administering fluoride
to their children and they want to make sure they don't overdose.
6. IWB Update—George Rhine/Janet Zeider
Commissioner Rhine reported there was an appeal for a refund on a residential leak. It was
resolved to split the remaining cost with the homeowner. The homeowner promptly fixed the
problem; it was expensive.
As a non-agenda item,Commissioner Rhine made comment to the IWB board that the board
ought to be proactive in deciding how it will handle the inclusion of the City of Bull
Mountain,if and when the vote is passed,rather than wait to the very end. Whether that is a
charter issue or whether they want to try and assign that to the TWB board to handle or what,
but somehow if the City of Bull Mountain is formed,then that entity needs to be a party to the
IWB. Commissioner Rhine indicated his comments were acknowledged. Because it was a
non-agenda item,there was no resolution.
7. Non-Agenda Items
When there is a light agenda,Mr. Koellermeier indicated he would like some direction from
the board as to whether they want to continue to meet or give him the authority to talk to the
Chair(or Vice Chair)to determine if a scheduled meeting could be cancelled. The board
members discussed their options regarding meeting practices making reference to by-laws,
state laws and Mr. Balfour's comments. As a suggestion,Mr. Koellermeier said we can
schedule monthly meetings. A week before the meeting,Mr.Koellermeier will discuss the
agenda with the Chair(or Vice Chair). If it is determined to be a light agenda, a decision may
be made to cancel the scheduled meeting. A meeting cancellation notice would be posted on
the web site and public buildings.
8. Set next meeting date—September 25,2006,at 7:00 p.m.
9. Adjournment
Commissioner Delphine motioned to adjourn,Commissioner Rhine seconded the motion, and
the board voted unanimously to adjourn the meeting at 7:30 p.m.
