4. Water Supply Update
Mr. Goodrich reported:
■ Average water use for the month of November was 4.11 million gallons per day
(mgd). This amount was slightly above November 2011 water use.
■ Injection into aquifer storage and recovery (ASR) #2 is accruing at a rate of about
1000 gallons per minute. To date ASR#2 has approximately 15 million gallons of
water stored. Once ASR#2 has reached its targeted storage goal of 200-250
million gallons, the City of Tigard (COT) will begin injecting into ASR#1.
■ ASR#3 is in design. Construction will begin in fiscal year 2014.
5. City of Tigard Future Water Supply Development—Dennis Koellermeier
Mr. Koellermeier reported:
• The City of Sherwood recently completed the construction of water pipelines
and facilities from the Willamette River Treatment Plant in Wilsonville to
Sherwood's water distribution system.
■ In order to evaluate future Willamette River water supply scenarios for the
Tigard Water Service Area,Tigard contracted with Murray, Smith &Associates
(MSA). MSA provided a conceptual analysis of the following scenarios:
➢ Supply development in partnership with Wilsonville and Sherwood.
➢ Major regional supply development with partners.
Brian Ginter,P.E., Murray Smith &Associates, Inc. gave a PowerPoint presentation
titled the Future Water Supply Development Concept Analysis. The presentation is on
file in the IWB record.
Presentation highlights:
■ Mr. Ginter discussed the two scenarios. Both would:
➢ Connect the Willamette River supply to Tigard's 10-Million-Gallon
Reservoir.
➢ Deliver 25 mgd to the COT in the year 2030.
■ Scenario 1-Supply Development in Partnership with Wilsonville and Sherwood.
➢ Tigard may participate in the expansion of existing infrastructure and
buy into excess capacity when available.
➢ Existing infrastructure was built in good economic times, and there is a
firm number on the cost, so the potential buy in would be lower than
scenario 2.
➢ Total Estimated Project Cost,Year 2030 Dollars - $170.6 million
■ Scenario 2-Major Regional Supply Development with Partners.
➢ Costs and elements will vary depending on the number of regional
partners.
➢ Infrastructure is not constructed and is still at the conceptual stage.
➢ Significant transmission costs can be anticipated.
➢ Willamette River Water Treatment Plant expansion would require
construction of a new facility running parallel to existing treatment
plant.
➢ Potential partners are Sherwood,Wilsonville, Hillsboro,Tualatin and
Tualatin Valley Water District (TVWD).
➢ Total Estimated Project Cost,Year 2030 Dollars - $371.4 million
Mr. Ginter discussed the different phasing options of the two scenarios.
Mr. Koellermeier stated the Lake Oswego partnership is projecting a total project cost of
$230 million in 2016 dollars. Tigard will likely be responsible for a little more than 50
percent of this cost.
The board discussed Tigard's Charter. It requires Tigard voters to approve the
Willamette River supply before it can be used as a drinking water source for Tigard
citizens.
Mr. Koellermeier stated:
■ The PowerPoint presentation was for informational purposes.
■ The Sherwood/Wilsonville partnership is the most economical scenario.
■ COT will likely need to decide whether to pursue the Sherwood/Wilsonville
partnership within the next 18 months. A financial commitment (of
approximately$5 or $6 million) would be required if Tigard moves forward with
this scenario.
■ Currently COT has no legal obligation to participate in the
Sherwood/Wilsonville partnership.
